Abstract

Aims: To evaluate the oral hygiene and gingival health among secondary school students and to find ifthere was any variation between age and sex groups in Mosul City Centre. Material and Methods: Asample of 630 students aged 16–18 years old (278 males, 352 females) were examined using plaqueindex score and gingival index. The clinical examinations were carried out in the school using planemouth mirrors, WHO periodontal probes to detect the dental plaque and gingival health. Results:Showed that the mean plaque score for the total sample was 0.96, the plaque index increased with age.Females reported less mean plaque scores than males with statistically significant difference betweenthem. The mean gingival score was 0.56 for the total sample and it increased with age. There was asignificant difference between males and females. The study revealed that 35.9% of the total sampledid not brush their teeth. Therefore the objective of dental health education to those subjects is to brushtheir teeth regularly and to improve the effectiveness of oral hygiene practice. Conclusion: Periodontaldisease is indirectly related to the exposure of bacterial plaque for long time which calls forcoordinated planning of preventive strategies and urgent priorities

Abstract

An analysis was performed on the treated water from two water treatment plants in Baghdad city. This analysis was used to evaluate the stability of the treated water from these plants and that will flow in the distribution system to consider its corrosivity. The variation in water stability with time and distance from the north to the south of Baghdad was indicated. The analysis showed that the flowing water in the distribution system in Baghdad is corrosive to very corrosive water by calculating Ryznar stability index (RI). In Al- Karkh WTP in the north, RI maximum ranged between 7.958 to 9.403 where RI minimum ranged between 7.03 to 7.915. Where in the south Al-Rasheed WTP, RI maximum ranged between 7.119 to 8.63 and RI minimum ranged 6.679 to 7.994. The corrositivity of water decreased in the water flowing down stream. The water quality parameters affecting RI was discussed which were calcium, alkalinity, total dissolved solids and pH.

Abstract

Background: Polycystic ovary syndrome (PCOS) is one of the most common endocrine disorders affecting women in their reproductive age.It is characterized by anovulation or oligo-ovulation and hyperandrogensim.Androgen excess is the central defect in polycystic ovary syndrome. It is a complex disorder affects general health in addition to oral health.This study aimed to assess the gingival health status among a group of women with polycystic ovary syndrome as well as to estimate the levels of salivaryfree testosterone in unstimulated saliva in relation to gingival health condition.Materials and methods: Sixty two women with an age range 20-25 years old and with a body mass index range18.5-24.9 (normal weight) were included in this study. They were divided into two groups; the study group which included thirty one women with polycystic ovary syndrome, those women.nattended Babylon Teaching Hospital/ Infertility Center and the control group which included thirty one women with regular menstrual cycles,without clinical or biochemical features of hyperandrogenism and ultrasound exclusion of polycystic ovary (without polycystic ovary syndrome). Collection of unstimulated salivary samples was carried out under standardrizedconditions, salivary free testosterone levels were estimated. Plaque index of Silness and Lӧe (1964) was used to assess dental plaque. While gingival index of Lӧe and Silness (1963) was used to assess gingival inflammation. Data analysis was conducted through the application of the (SPSS version 18). The analysis of data included: Mean, Standard deviation, t-test, Pearson Correlation (r), Receiver Operative Characteristics Curve (ROC curve).Results:Results showed that the mean value of plaque index was found to be higher in the control group (1.18±0.03) than that in the study group (1.00±0.08) with statistically highly significant difference (p<0.01).While the mean value of gingival indexwas higher among the study group (1.52±0.06)than that in the control group (1.31±0.05)with statistically highly significant difference (p<0.01).Salivary levels of free testosterone among women with polycystic ovary syndrome (44.12±1.37 pg/ml) were found to be higher than that of control (18.50±0.87) with statistically highly significant difference (p<0.01).The results in this study showed that the correlations between salivary free testosterone with the oral variables (plaque index, gingival index) were statistically not significant (P>0.05).In order to assess the specificity and sensitivity of the use of salivary free testosterone as a diagnostic tool, statistical analysis of Receiver Operative Characteristics Curve (ROC) was used and predictive Value Measurmentswere done in this study. The results showed that the area under the curve for salivary free testosterone test was (1.000) with highly significant p-value (p<0.01). The best optimal cut off point for salivary free testosterone was (30.86) with (100%) sensitivity and specificity, indicating a very good predictive capacity for using salivary free testosterone as a marker for the diagnosis of polycystic ovary syndrome.Conclusions : It was concluded that gingival inflammation was high among women with polycystic ovary syndrome. Furthermore, salivary levels of free testosterone were found to be high among women with polycystic ovary syndrome

Abstract

Information about soil consolidation is essential in geotechnical design. Because of the time and expense involved in performing consolidation tests, equations are required to estimate compression index from soil index properties. Although many empirical equations concerning soil properties have been proposed, such equations may not be appropriate for local situations. The aim of this study is to investigate the consolidation and physical properties of the cohesive soil. Artificial Neural Network (ANN) has been adapted in this investigation to predict the compression index and compression ratio using basic index properties. One hundred and ninety five consolidation results for soils tested at different construction sites in Baghdad city were used. 70% of these results were used to train the prediction ANN models and the rest were equally divided to test and validate the ANN models. The performance of the developed models was examined using the correlation coefficient R. The final models have demonstrated that the ANN has capability for acceptable prediction of compression index and compression ratio. Two equations were proposed to estimate compression index using the connecting weights algorithm, and good agreements with test results were achieved.

ان معرفة خصائص الانضمام للتربة مهم في التصميم الجيوتقني. نظرا للوقت والنفقات المتضمنة في إجراء اختبارات الانضمام، فإن المعادلات التجريبية التي تتضمن مؤشرات خصائص التربة مطلوبة لتقدير مؤشر الانضغاط. وعلى الرغم من اقتراح العديد من المعادلات التجريبية المتعلقة بخصائص التربة، فإن هذه المعادلات قد لا تكون مناسبة للحالات المحلية. الهدف من هذه الدراسة هو إقامة علاقة ارتباط بين خصائص الانضمام والخصائص الفيزيائية للتربة المتماسكة. وقد تم استخدام الشبكة العصبية الاصطناعية (ANN) للتنبؤ بمؤشر ونسبة الانضغاط من الخصائص لأكثر بساطة. تم استخدام مئة وخمسة وتسعين نتيجة اختبار انضمام للتربة التي تم أخذ عيناتها من مواقع البناء المختلفة في مدينة بغداد. استخدمت 70٪ من هذه النتائج لتدريب نماذج الـ(ANN) وباقي النتائج قسمت بالتساوي للاختبار والتحقق من صحة نماذج الـ(ANN). تم فحص أداء النماذج الرياضية المطورة باستخدام معامل الارتباط R. وقد أظهرت النماذج النهائية قدرة الـ(ANN) على التنبؤ باؤشر الانضغاط ونسبة الانضغاط بشكل مقبول. تم اقتراح معادلتين لتقدير مؤشر الانضغاط باستخدام خوارزمية أوزان الربط (connecting weights algorithm)، وتم التوصل إلى تقارب جيد مع نتائج الاختبار

Abstract

Background Periodontal health at the restorative gingival interface continues to represent one of the most diffcult challenges. Unfortunately, they only mimic the physical and morphological aspects of teeth, as they are limited by the absence of the ‘ideal material’ that would provide characteristics similar to the normal tooth structure. Aims To determine the influence of class II amalgam and composite restorative materials on plaque accumulation, gingivitis and periodontal pocket depth. Materials and Methods One hundred patients were included in the study. The age ranged between (21-24) years old. The sample was composed of two groups (50 patients each), with an equal ratio of males and females. The tested restoration types were: amalgam class II (MO) and composite class II (MO) of 2-3 years. The following periodontal parameters: plaque index (PI), gingival index (GI) and pocket depth (PD) in mm were recorded for each restored tooth compared with non-restored tooth on the other side of the mouth as a control. Results The results showed that amalgam induce the higher means of plaque, gingivitis and pocket depth compared with composite. The mean of the three parameters, as compared to control group, were statistically higher in the restored amalgam surfaces (p<0.05). For composite restoration the means of the three parameters were also higher but not in signifcant levels for both plaque index and gingival Index, except for pocket depth of the restored surfaces were signifcantly higher than the controlled surfaces. However, there were no signifcant differences in the ranks of the three mesial indices of patients having amalgam in comparison with those having composite. Conclusion This study suggests that composite restorations did not have a signifcant advantage on periodontal health over amalgam restorations for Class II posterior teeth.

Abstract

Diabetes mellitus plays a substantial role in the dentition and oral health. Oral manifestation identified with Diabetes mellitus may have a strong inclination to periodontal disease. This study was to assess the relation of salivary pH, flow rate, and buffer capacity with severity of periodontitis among patients with type 1 diabetes mellitus in comparison with healthy volunteers. A study was conducted on 58 volunteers (aged 18-25 years), of them 28 volunteers had type I diabetes mellitus (study group), and 30 volunteers were health persons with absence of medical conditions that could decrease salivary flow (control group) from both genders. Stimulated whole saliva was collected, salivary flow rate (ml/min), pH, and buffer capacity were measured and they examined orally to evaluate the plaque index according to Sinless and Lӧe (1964) and the calculus index according to Green and Vermillion (1964), all information recorded. There were a significant difference (p-value<0.01) in plaque index in the diabetic group in compared with heathy group, while the calculus index shown no differences. The salivary pH decreased significantly (p<0.045) in diabetic group in compared with heathy group, while other parameters (salivary flow rate and buffer capacity) had no effect. There were no differences in both genders.Periodontitis can be seen in the same severity in both genders, and in diabetic patients more than the normal individuals. The clinical indicators of periodontitis that observed in diabetic patients are more common than the normal individuals.
