المستخلص: 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

المستخلص: 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

المستخلص: 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.
