Abstract: This in vitro study was conducted to evaluate and compare the efficiency of XP - endo Finisher, EndoActivator sonic irrigation system and the NSK Varios ultrasonic irrigation system in removing dentin debris at three levels of root canals and to compare the percentage of dentin debris among the three levels for each irrigation system. Sixty freshly extracted upper molar teeth with straight palatal root canals were used in this study. All canals were prepared with ProTaper NEXT rotary files to size X4, 1mm from the anatomic apex with irrigation of 1 ml 2.0% NaOCl between the files. After that the samples were randomly distributed into three groups of twenty samples each, irrigated with 1 ml 2.0% NaOCl, followed by irrigant activation for 60 seconds with three different irrigation systems; group one, by using the XP - endo Finisher; group two, by sonic irrigation using the EndoActivator system; and group three, by ultrasonic irrigation using the NSK Varios, then all the groups received a final rinse of 5 ml 2.0% NaOCl. After the final rinse, the roots were split longitudinally into two parts and photographed with a professional digital camera. The digital images were then transferred into a computer and opened in Adobe Photoshop CC 2015 software and the canal was magnified 200x. The percentage of dentin debris remaining at the apical level (0 - 3mm), the middle level (3 - 6mm) and the coronal level (6 - 9mm) was calculated by dividing the number of pixels occupied by the dentin debris at each level by the number of pixels representing the entire canal area. Data were analyzed statistically by ANOVA and LSD at 1% and 5% significant levels. This study showed that cleaning the canal with the XP - endo Finisher or NSK Varios ultrasonic irrigation system resulted in significantly cleaner canals (P<0.01) than the EndoActivator sonic activation system at all canal levels. The XP - endo Finisher resulted in cleaner canals than the NSK Varios ultrasonic irrigation system at all levels, but the difference is not statistically significant (P>0.05). The apical level of all the canals showed a greater amount of dentin debris (P<0.01) compared to the middle and coronal levels, regardless of the irrigation device used.

Abstract: t is important to analyze and compare the stresses induced in different composite material types during load application to know which type of composite will behave as preferred under the loading in the same circumstances. This study aimed at measuring and comparing the stress induced in Filtek ™ Z350 XT (3M ESPE) composite, Tetric EvoCeram ® (ivoclar vivadent) composite and BRILLIANT ™ NG (Coltène/Whaledent) composite experimentally and numerically.Experimental analysis included cavity preparation in the Brass block with a concave (U - shape) cavity which represent a proximal cavity preparation. This cavity was used as a mold for sample preparation. The internal line and point angles of the cavity (mold) were rounded and the dimensions of the cavity (mold) were 10mm × 10mm × 10mm (Total height of the box × Width of the top side of box × Length of the top side of box). The internal diameter of “U” was 5 mm at the base of the box. The mold was used to prepare forty five samples, fifteen samples for each type of composite material. So, three groups were prepared : Group A filled with Filtek ™ Z350 XT composite material, Group B filled with Tetric EvoCeram ® composite material and Group C filled with BRILLIANT ™ NG composite material.Electrical strain gauge (Tokyo Sokki, Japan) was embedded in composite material horizontally at the same level in each sample. Static load of 50 N was applied perpendicular to the center of the occlusal surface of composite restoration in each sample testing. The strain gauge was connected to a Wheatstone bridge with a signal amplifier which measures the strain during load application and gives the amplified signal from (0 to 4.8 volt) to LabJack data acquisition where a stream software give the final values of strain with the aid of a scaled equation of voltage. Then, the von Mises stress (effective stress) was calculated by using equations. Numerical analysis was done by using ANSYS 16.1 - (2015) (finite element tool) software that was used to create the 3 - Dimensional models represented the same materials and dimensions used experimentally. The physical characteristics of the composite models were inserted in the software which included Elastic modulus and Poisson’s ratio (?). Analysis was selected in a finite element method according to boundary conditions. A mesh size and an element size were estimated during the study. The stresses were calculated at static load of 50 N with the ANSYS 16.1 - (2015) software.The data were analyzed statistically by One - way ANOVA test and Least Significant Difference (LSD) test. One - way ANOVA test and LSD test results showed that there was a highly significant difference (P<0.001) presented between groups A and B, groups A and C and between groups B and group C. The Stress induced in BRILLIANT ™ NG composite after load application was the lowest stress value followed by Tetric EvoCeram ® composite and followed by Filtek ™ Z350 XT composite which was the highest stress value experimentally and numerically.

Abstract: Although investigators have evaluated the microleakage of porcelain laminate veneers, there is insufficient data regarding the durability of porcelain laminate veneers bonded to existing composite fillings. The aim of this study was to evaluate the microleakage of porcelain veneers restorations fabricated from two types of CAD/CAM ceramic blocks bonded to teeth with or without composite class V composite filling.Forty eight sound, crack - free human maxillary first premolar extracted for orthodontic reasons were selected for this study. Teeth were divided randomly into.2 main groups, which further divded into 2 groups (12 sample each). Group A1 : IPS e.max CAD veneers with standardized class V composite filling, Group A2 : IPS e.max CAD veneers, Group B1 : VITA Suprinity veneers with standardized class V composite filling, Group B2 VITA Suprinity veneers. The class V cavities was restored with nanofilled composite (Filtek™ Z350 XT, 3M ESPE). Standard veneer preparations were made using Ceramic veneer burs system (Keramikveneers. de, Komet). All the veneers were milled by CAD/CAM technology (CEREC MC XL, inLab SW 15, Sirona Dental Systems) Composite fillings (groups A1 and B1) were sandblasted with alumina oxide.Porcelain veneers were cemented in place using light - cured resin cement (Rely Veneer Cement, 3M ESPE), Then the specimens were stored at 37? in distilled water for 2 weeks. Then mechanical load cycling (50,000 load cycle of 49 N at 2.5 Hz) and thermocycling procedure (500 cycles of 5 - 55 Co with 20 sec dwell time) were done. The specimens’ crowns were immersed in 2% methylene blue dye for two days, then mounted in clear acrylic before sectioning with a 0.35 mm microtome. Microleakage percentage were recorded using stereomicroscope and ImageJ program. Results were checked for normality of distribution (Kolmogorov - Smirnov test and Shapiro - Wilk test), and were analyzed with twoway ANOVA and independent samples t - tests. Two way ANOVA shows the significant effect of type of ceramic restoration and the highly significant effect of composite filling, however, the interaction between the main factors was non - significant. The results showed that the lowest mean of microleakage percentage was recorded for group A2 (4.6058% ± 1.5091) which considered statistically significant compared to group B2 (6.105%±1.456), and statistically highly significant compared to group A1 (6.6075%±1.3259) while group B1 recorded the highest mean of microleakage percentage (7.3158%±1.38713). In conclusion, the type of ceramic restoration and the presence of class V filling both had significant effects on microleakage of porcelain veneers. IPS e.max CAD veneers had significantly lower microleakage percentages compared to VITA Suprinity veneers. The presence of class V composite filling within the cervical finishing line of porcelain veneers had a highly significant higher microleakage percentage compared to groups without composite filling.

Vertical root fracture is one of the most frustrating complications of root canal treatment, which often results in tooth extraction. The aim of this in vitro study was to compare the effect of different Nickel Titanium instruments (ProTaper Universal, EndoSequence, ProTaper Next and RECIPROC) on the dentinal wall in term of dentinal defects.Seventy - five straight palatal roots of freshly extracted human maxillary first molars teeth were used in this study, the palatal roots were sectioned at 11 mm from the apex and wrapped with two layers of aluminum foil, then placed in the center of elastic silicon mold. Fifteen roots were left unprepared to serve as a negative control group, the remaining 60 roots were divided into 4 groups, each group contained 15 roots : • Group I was prepared by rotary ProTaper Universal system.• Group II was prepared by rotary EndoSequence system.• Group III was prepared by rotary ProTaper Next system.• Group IV was prepared by reciprocating RECIPROC system.All canals were prepared to MAF # 40. After each file size of the (rotary files) or after three pecking motion of the (reciprocating files), the file was removed from the canal and the canal was irrigated with 1 ml of 2% of sodium hypochlorite. All files were cleaned periodically to prevent clogging of flutes during instrumentation. The canal remained patent by insertion size 15 K - file.When the instrumentation was completed, the roots were then embedded in a clear acrylic resin blocks and each root was sectioned into three levels : apical, middle and coronal. All samples were examined from coronal direction under Stereomicroscope. The number and the type of dentinal defects were recorded and classified. The collected data was tabulated and subjected to statistical analysis using chi - square test.The EndoSequence group showed the lowest number of dentinal defects followed by ProTaper Next group and then ProTaper Universal group. The highest number of dentinal defects were observed in RECIPROC group. Chi - square test showed that there were highly significant differences among groups (P < 0.01). The results showed a non - significant difference between EndoSequence and Protaper Next group (p > 0.05), and a significant difference with ProTaper Universal group (P < 0.05) and a highly significant difference with RECIPROC group (P < 0.01). The ProTaper Next group showed a significant difference with ProTaper Universal group and a highly significant difference with RECIPROC groups. There was no significant difference between RECIPROC and ProTaper Universal groups.

Abstract: الربو القصبي المزمن يمثل مشكله صحيه جديه في كل العالم وهو عادة يبدا في عمر الطفوله ويبقى المريض في كثير من الاحيان يتعاطى العلاجات المستنشقه مدى الحياة.انتشار الربو القصبي يزداد في كثير من دول العالم مما يجعله احد الامراض المعيقه والمهدده للحياة باعتبا | Asthma is a serious global health problem that usually starts in childhood and continues along patient’s life and most of them have to take inhaled therapy lifelong. The prevalence of asthma is rising in many countries of the world, making asthma one of the most disabling and life threatening diseases effecting patients with different age groups and social classes with variable clinical spectrums and outcomes starting from mild to severe disabling syndrome rendering nonproductive individuals to severe life threatening and sometimes fatal disease. Those patients continue inhaled steroid therapy for long duration, considered by GINA as first line treatment , however such a treatment is associated with local adverse effects on oral tissues, and one of the main concerns is the development of oral candidiasis, a chronic, potentially invasive, infection of oral tissues with fungus candida species resulting in failure of treatment. The scientific interests about such a serious complication have been raised over the past years and debates continued as the candida is considered one of the normal flora of the oral cavity in most of healthy population, however oral candidiasis in pathogenic forms still occur in immunocompromised patients including asthmatics on inhaled corticosteroid therapy.Aim of the study1. To investigate the effect of inhaled corticosteroid therapy in form of Beclomethasone Dipropionate250 microgram/dose CFC free in asthmatic patients on salivary candidal shed estimating by Real Time quantitative Polymerase Chain Reaction (RT qPCR) applied on direct unstimulated saliva samples.2. Evaluation of this shed as prediction of occurrence of oral candidiasis. Patients, Materials and MethodsThis study was conducted at Al Zahraa consultational Asthma and Allergy center - Baghdad Al Karkh Health Directorate from September 2013 to February 2014.The included patients were divided into 3 groups. Group A included asthmatic patients on inhaled Beclomethasone therapy, group B included asthmatic patients that never used any form of inhaled steroid therapy and group C was those asthmatic patients on inhaled Beclomethasone therapy who developed oral candidiasis. All patients were receiving two daily doses. The same exclusion forma was applied to choose Group D who were control healthy individuals. Each included patients and control cases were instructed to give saliva samples in the standard way and samples taken for estimation of candidal count by real time quantitative Polymerase Chain Reaction.Results During the study period, 698 patients were examined, however only 63 patients were included in the study. Those 63 were classified as follows : 28 patients were found on group, 28 were found on group B and only 7 patients were found on group C and 20 cases were selected in group D as a control.Group C patients were having the highest salivary candidal shed (mean=58.7x106 cn/ml) and longest duration of asthma (Mean=2718 days) and longest duration of Beclomethasone therapy (Mean=2224 days) and this was significantly higher than other groups (p<0.05).Group A patients were having the second highest rank after group C in regard of salivary candidal shed and both duration of asthma and Beclomethasone therapy. Inside each group, duration of asthma and duration of Beclomethasone therapy were associated with moderate positive correlation with salivary candidal shed (R>0.5).Age difference between groups were insignificant and age factor had no correlation with salivary candidal shed inside the groups.Discussion : Salivary candidal shed over the groups was directly related to the duration of inhaled Beclomethasone therapy and duration of asthma. They are significantly higher (p<0.01) as we go further from each group to the next, both appear as the reason behind increased candidal shed in groups A and C.The salivary candidal shed curve will gave us a very useful tool for follow up those patients on inhaled steroid therapy ,In addition , predict the risk of developing oral candidiasis and when to interfere prior to the establishment of Oral Candidiasis state as that we have noticed in the group C, in which it was recommended to stop inhaled steroid therapy and the patients would lose the benefits of the therapy.Conclusions1. Resting saliva samples with realtime quantitative PCR was a rapid and accurate tool in diagnosis of oral candidiasis.2. Salivary Candidal Shed could be used as a tool in predicting oral candidiasis in asthmatic patients on inhaled Beclomethasone therapy.3.Longer duration of asthma and longer duration of Beclomethasone therapy were associated with increased salivary candidal shed and established oral candidiasis have the highest amount of shed.4. Candida albicans are present in the oral cavity of any individual of our population

Abstract: Resin composites have improved greatly since their introduction and are now the materials of choice for most of the restorations. This study was conducted with aim of comparing in vitro the marginal adaptation of three different, low shrink, direct posterior composites Sonic fill™ (nanohybrid composite), Filtek™ P90 (Silorane - based composite) and Filtek™ Z350 (nanofill composite) of a standardized Class V cavity after thermoal cycling. Sixty sound, freshly extracted human premolars were prepared with standardized Class V cavities. The specimens were divided into three groups of twenty teeth each according to the material used : Group A : The teeth were restored with Sonic fill™ posterior composite unidose capsules, Group B : The teeth were restored with a silorane - based posterior composite (FiltekTM P90), Group C : The teeth were restored with nanofill methacrylate - based composite (Filtek™ Z350 XT).After specimens were stored in distilled water at 37°C for 7 days, all specimens were subjected to thermocycling at (5° to 55 °C), then immersed in 2% methylene blue dye for 24 hours. For each group microleakage at the occlusal and gingival regions was estimated by determining dye penetration using scoring system under steromicroscope (10X). The statistical analysis of the results showed that, Filtek™ P90 silorane based composite exhibited the lowest mean of microleakage, with statistically highly significant difference (P < 0.01) when compared with Sonicfill™ composite and Filtek™ Z350 XT nanofill composite. On the other hand, the results of this study showed that Sonic fill™ composite exhibited no significant difference (P > 0.05) as compared with Filtek™ Z350 XT nanofill composite. Also, the results in this study showed that there is a highly significant difference (P < 0.01) in dye penetration between occlusal and gingival regions for each group

Abstract: اضطرابات المفصل الفكي الصدغي تشير الى مصطلح مركب يحتوي على عدة حالات تتضمن المفصل الصدغي,التركيبات المحيطة او كلاهما.اضطرابات المفصل الفكي الصدغي هي مجموعة اعراض معقدة اكثر من كونها حالة معينة واحدة, ويعتقد انها تنتج من عدة عوامل مثل : العوامل الجينية, ال | Tempromandibular disorders is a collective term, embracing several clinical problems involving the muscles of mastication, temporomandibular joint (TMJ), or both.Tempromandibular disorders is a symptom complex rather than a single condition, and it is thought to be caused by multiple factors like : genetic, developmental and metabolic.TMDs form a cluster of related disorders with common symptoms which include localized pain, limited or asymmetric movement, and clicks or grating on opening.Psoriatic arthritis is a chronic inflammatory arthropathy that affects patients with psoriasis. Psoriatic arthritis is most commonly a seronegative oligoarthritis found in patients with psoriasis and therefore occurs more commonly in patients with tissue type HLA - B27. The clinical findings for Tempromandibular Psoriatic arthritis are pain, tenderness, limitation of movement , joint stiffness, clicking as the jaw is opened or closed, difficulty in opening the mouth, locking of the jaw,and crepitations. These findings are essentially the same as for Tempromandibular disorders.• Objective of the study : • To determine the extent of tempromandibular joint involvement in patients with psoriatic arthritis.• To correlate between clinical findings and radiographic finding.Materials and method : In this study 98 patients were selected ,50 male and 48 female, their age ranged between(18 - 68)years. They were collected at Al - yarmook teaching hospital/department of dermatology during the period from ( NOV 2014 - May 2015).They were diagnosed as having psoriatic arthritis by a dermatologist according to (Moll and Wright diagnostic criteria 1973).These patients were sent to rheumatoid factor test RF to exclude the presence of rheumatoid arthritic disease, then the patients were exposed to CT scanning for the Tempromandibular joint in Al - Yarmook teaching hospital for screening the involvement of TMJ with psoriatic arthritis by the presence of any radiographic changes such as erosion, flattening,osteophyte and sclerosis in the condylar head.Results : The result of the study showed that the mean age of psoriatic arthritic patients in TMJ was (44.2) years, and the female percentage was (48.4%) and the male was (51.6%). Psoriatic arthritis in TMJ showed high significance in the unilateral side symptoms (100%) it was significant in patients with positive family history (54.8%), and non significant in the right/left ratio (41.9%). Oligo type was found in twenty six patients (83.9%) with significant p - value. Clinically, all symptoms including clicking, tenderness and tempromadibular joint pain were highly significant, limitation showed (54.8%), TMJ pain showed (64.5%) and tenderness showed (54.8%).Radiologically : CT scan showed sensitivity for erosion in TMJ (54.8%), for osteophyte (32.3%), for condylar flattening (16.1%) and for sclerosis (9.7%) while specificity for all were (100%). Association between clinical symptoms and radiological changes showed non significant correlation. Conclusions : Psoriatic arthritis of TMJ has been found oftenly unilateral (oligo type). Female/ male ratio is about 1 : 1. nearly 50% of patients were having limitation in mouth opening. Most of the patients were having positive family history.The development of psoriatic arthritis in TMJ is related to the duration of the disease. Plaque psoriasis is the most associated type with the psoriatic arthritis in TMJ. Most of patients with psoriatic arthritis show psoriatic nail changes. The most radiographic findings found in patients with psoritic arthritis was erosion in the condylar head. There is association between clinical and radiologic findings for psoriatic arthritis in TMJ.

This study was performed to compare the marginal fit changes and facture resistance of metal ceramic crowns constructed from Ceramill Sintron metal coping veneered with three different porcelain veneering materials (Vita Master Koromikos VMK, Willi Geller Creation CC and GC initial MC). Also evaluating the influence of thermocycling on load at fracture value. The method included the use of master brass die which was milled to represent the prepared maxillary central incisor. Sixty metal copings were milled directly using Ceramill Sintron blank, then divided randomly into three groups. Each group consist of twenty metal copings, then veneered with porcelain : VITA for group A, Creation for group B and GC for group C. The marginal gap was measured before and after porcelain veneering for each group using travelling light microscope, then marginal fit changes was calculated. Fracture resistance test was done by Instron®, the master die was duplicated to sixty analogs then each analog was fixed into acrylic base. After that each crown was cemented onto the corresponding die analog using zinc phosphate cement. Ten samples of each group were subjected to compressive loading to fracture and other ten subjected to thermocycling followed by compressive loading to fracture.The result showed that GC group was highly significant different from other tested groups in marginal fit changes, whereas there was no significant different between VITA and Creation group. While there was significant difference among tested group at (P < 0.01) in fracture resistance, and the effect of thermocycling process did not significantly reduce the load at fracture for all groups.This study concluded that GC group present the least marginal fit changes, while the fracture resistance was highest for VITA group follow by Creation then GC. Thermocycling reduce load at fracture but not significantly.

Abstract: تحضير قناة الجذر يشمل كلا من تشكيل وتوسيع المساحة اللبية بالاضافة الى تطهيرها من الجراثيم، من دون اي خطا اجرائي هو من اقصى درجات التفضيل. حديثا، في مجال تطبيقات حشوات الجذور، ادوات النيكل تيتانيوم اصبحت تستخدم بصورة شائعة لتنظيف وتشكيل قناة الجذر. ادوات ا | Root canal preparation includes both shaping and enlargement of the endodontic space in conjunction with its disinfection, without any procedural error is of the utmost preference. Recently, in endodontic practice, the nickel - titanium instruments are used commonly for the preparation of the root canal space. Nickel - titanium instruments are much more flexible than stainless steel files and have superior cutting efficiency. Super - elasticity of nickel - titanium rotary instruments allows the clinicians to produce the desirable tapered root canal form with a reduced tendency to canal transportation and instrument fracture. The target of this study was to measure and compare the canal transportation and centering ability of iRaCe and ProTaper NEXT nickel titanium instruments with ProTaper Universal instruments in simulated curved canals at different levels and compare canal transportation and centering ability among different levels for each tested instrument.Sixty simulated curved canals of 40°curvature were randomly divided into three groups of twenty canals each; the first group (group A) was prepared with iRaCe instruments, the second group (group B) was prepared with ProTaper NEXT instruments and the third group (group C) was prepared with ProTaper Universal instruments. The canals were prepared to an apical size 30 by crown - down instrumentation technique. Removal of material was measured at five different levels : at the canal orifice (O), half way to the orifice in the straight sections (HO); the beginning of the curve (BC); the crest of the curve (AC); the end point (EP). Pre - and post - operative photos of the simulated canals were taken in a standardized technique at magnification of 40X. An assessment of canals shape has been determined using Photoshop CC 2014 and AutoCAD 2014 software program. The data of canal transportation as well as centering ratio were analyzed statistically using Shapiro - Wilk, ANOVA and LSD tests.Within the limitation of this study, it is shown that canals preparation with the three designs of NiTi instruments produced canal transportation. However, the iRaCe instruments showed a significantly less canal transportation and a significantly better centering ability than both ProTaper NEXT and ProTaper Universal instruments at all levels of measurements, followed by ProTaper NEXT instruments that showed a significantly less canal transportation and significantly better centering ability at all levels when compared with ProTaper Universal, while the ProTaper Universal instruments showed the highest values of canal transportation and the worst ability to stay centered in the canals at all levels. Considering the direction of canal transportation, the iRaCe instruments showed minimal transportation towards inner aspect of canal at coronal and at the apex of curve and towards outer aspect of canal at middle, beginning of curve and at the end point of the preparation, while ProTaper NEXT instruments were showed transportation usually towards the inner aspect of the canal at middle part of the canal and towards the outer aspect at coronal, beginning of curve, apex of curve and at the endpoint of the preparation, while ProTaper Universal files were usually towards the inner aspect at middle part of the canal and towards the outer aspect at coronal, beginning of curve, apex of curve and at the endpoint of the preparation.

Abstract: اضطرابات المفصل الصدغي والاضطرابات الفموية يبدو انها مشكلة متكررة في المجتمعات الحديثة. ويرتبط الباثولوجيا السببية المفصل الصدغي الى العضلات، واقواس الاسنان، ودواعم الاسنان. وتشمل الاسباب الرئيسية على حد سواء العوامل الفيزيولوجية المرضية والنفسية وا | Bagkground : The temporomandibular disorders (TMD) and oral parafunctions seem to be a frequent problem in modern societies. The etiopathology of the temporomandibular joints is related to muscles, teeth arches, and periodontium. Their main causes involve both pathophysiological and psychosocial factors. In the literature, a significant impact of the psychoemotional factor is reported, comparable to the impact of other factors concerning physical health such as systemic diseases, malocclusions, loss of teeth, and traumas. Stress, fatigue, anxiety, depression, sleep disorders, and a fast pace of life affect negatively the human psyche.Aim of study : The aim of the study was to assess the prevalence of temporomandibular disorders (TMD) and oral parafunctions, as well as their correlation with psychoemotional factors among dental students by using diagnostic criteria (DC/TMD).Subjects, materials and methods : the sample’s size of 407 students (169 males and 238 females) of dental college (100 fifth stage , 102 fourth stage ,99 third stage and 106 second stage ). Firstly students subjected for stress questionnaire (perceived stress scale - 10) , secondly they subjected to different clinical and questionnaire measures according to diagnostic criteria of temporomandibular disorders DC/TMD (axis1) which have standerized series of diagnostic tests based on clinical signs and symptoms , finally the dental students subjected for oral parafunctions questionnaire using oral behavior checklist.Results : the results obtained from this study showed that the prevalence of TMDs was significantly greater among students with oral parafunctions. We also observed that the prevalence of TMDs according to DC/TMD was higher among students with headache.In this study, the prevalence of psycho - emotional stress , TMD according to DC/TMD and oral parafunctions were higher in females than males and in fifth stage greater than other stages.Conclusion : • the prevalence of TMDs according to DC/TMD were significantly higher among females than males.• Oral parafunctions ( bruxism , cheek/lips biting , objects biting and nail biting ) showed greater prevalence in fifth stages than others and higher in females than males • In all stages females showed greater prevalence of psycho - emotional stress than males and among students of fifth stage the prevalence of psycho - emotional stress was higher than other stages.
