Successful restorations are dependent on the efficiency of the light-curing unit, the intensity of light, and its wavelength. This study evaluated the efficacy of LED light-curing units in private dental clinics in Tehran.&nbsp;</p> <p><strong>Materials and Methods:</strong> In this descriptive cross-sectional study, 320 light-curing devices in different private dental clinics were randomly evaluated. The radiometer (light-testing-meter) measured Light intensity, and also dust on the fan and cracks or scratches on the filter were directly observed. Moreover, the age of the device, the frequency of changing the bulbs and satisfaction of the dentist concerning the light-curing unit were recorded in questionnaires. Data were analyzed for Spearman correlation and t-test using SPSS software with p&lt;0.05 as the level of significance.</p> <p><strong>Results:</strong> The results showed that the intensity of 53.75% units was more than 300 mW/cm<sup>2</sup>. The power of 30.3% of curing light units was between 200 and 300 mW/cm<sup>2</sup>, and 15.9% had lower than200 mW/cm<sup>2</sup>. The light intensity has a negative relation with the age of the unit, frequency of bulb changing, and scratches on the filter and dust on the fan.</p> <p><strong>Conclusion: </strong>The results proved that the light intensity of about 46% of light-curing units, used in private dental practices and clinics, were inadequate. Since factors such as ageing of the light-curing devices, frequency of bulb replacement, increasing the amount of dust on the fan and scratches on the filter reduces the light intensity; therefore, regular quality control of these devices is necessary.</p> Nazanin Forghani ##submission.copyrightStatement## http://journalijrrd.com/index.php/IJRRD/article/view/30100 Sat, 07 Sep 2019 00:00:00 +0000 Assessment of Oral Health Knowledge and Behavior Related to Oral Hygiene Status among Selected Secondary School Students in Kasese District, Western Uganda http://journalijrrd.com/index.php/IJRRD/article/view/30101 <p><strong>Aims: </strong>Good oral health is essential for the well-being of Human being. However lack of knowledge, guidance and poor oral hygiene practices may lead to poor oral hygiene and predispose one to oral health diseases. This study assessed oral health knowledge and behavior related to oral hygiene status among selected secondary school students in Kasese District, Western Uganda.</p> <p><strong>Study Design:</strong>&nbsp; A descriptive cross sectional study was carried out among students from selected secondary schools of Kasese District, Western Uganda. Stratified sampling technique was used to recruit 278 participants among students of the selected secondary schools.</p> <p><strong>Methodology:</strong> Data was collected using closed and open ended questionnaires. The dependent variable was based on the participant’s responses if he/she had any decayed, missing or filled teeth <strong>(</strong>DMFT). Bivariate analysis was used to compute crude odds ratios for predisposing factors. The significant variables were then included in the multivariate model to obtain adjusted odds ratios for risks factors associated with occurrence of DMFT.</p> <p><strong>Results:</strong> Out of 278 participants interviewed, 108 (38.8%), 95% CI= (0.3325-0.4468) students had DMFT. There was a statistical significant relationship between the level of the knowledge and behavior of the students and their oral health status. For the Students who had never visited a dentist (95% CI; 1.177-3.315, aOR = 1.975, p=0.010) and those who brushed their teeth once a week (95% CI; 1.226-31.161, aOR = 6.180, p=0.027) were found to be more at risk of developing DMFT.</p> <p><strong>Conclusion:</strong> Poor oral health hygiene among secondary school students was significantly associated with frequency of brushing teeth and failure to visit a dentist. There is need to increase oral health education in secondary schools in order to encourage students to visit dentists regularly as well as improving the frequency of brushing teeth as this will positively impact on oral health behaviors and status.</p> Isaak Wavamunno, Adamu Almustapha Aliero, Alkali Bashir, Theophilus Pius, Collins Atuheire, Ibrahim Ntulume ##submission.copyrightStatement## http://journalijrrd.com/index.php/IJRRD/article/view/30101 Tue, 22 Oct 2019 00:00:00 +0000
