Background and aims. Predicting the teeth eruption time is a valuable tool in pediatric dentistry since it can affects scheduling dental and orthodontic treatments. This study investigated the relationship between the eruption time of first primary and permanent teeth and the variation in the eruption time considering socioeconomic status (SES) in a 9-year population- based cohort study.Materials and methods. 307 subjects were examined at bimonthly intervals during the first and second years of life and then at six-month intervals until the eruption of first permanent tooth. Eruption times of primary and permanent tooth were recorded for each child. A modified form of Kuppuswamy’s scale was used to assess the SES.Results. Among 267 subjects completed all follow-ups, the eruption time for first primary and permanent teeth indicated a direct strong correlation; in that one month delayed or early eruption of firstprimary tooth resulted in 4.21 months delayed or early eruption of first appearing permanent tooth (r = 0.91, n = 267, P <0.001). No significant correlation was observed between the eruption time of first primary and first permanent teeth and SES (P = 0.67, P = 0.75, respectively).Conclusion. The eruption timing for the first primary tooth had a correlation with the first permanent tooth eruption tim-ing, while SES did not have any influence on eruption times.

Oral health status is one of the health-related priorities in Iran. The present study was conducted with the aim to systematically review the status of oral health in Iran using the decayed, missing, filled teeth (DMFT) index. In this meta-analysis, all data available on DMFT were reviewed and 35 published studies were included in the study based on search strategy. To estimate overall DMFT and perform the meta-analyses, Comprehensive Meta-Analysis (CMA) software was used. Of all 876 articles, 35 were included in the study. A total of 21849 individuals were included in the meta-analysis. The overall DMFT index was 3.65 [95% confidence interval (CI), 3.01-4.34]. In addition, this rate was 2.30, 8.60, and 3.85 among children, adults, and children with mental/physical disabilities with (CI 95%, 1.76-2.95), (CI 95%, 6.10-9.60), and (CI 95, 2.98-4.80), respectively. Mean DMFT in the assessed published data was higher than that set forth by the World Health Organization (WHO). Further planning and taking effective preventive measures to improve the oral health status seems necessary.

Background and aims. There is no report on the apoptotic impact of Allium sativum L.(Garlic) on the oral squamous cell carcinoma (KB); hence, this study was designed to survey the apoptotic effects of garlic fresh juice (GFJ) on the KB cells.Materials and methods. MTTassay (MicrocultureTetrazolium Assay) was carried out to evaluate the cytotoxicity of GFJ on KB cells. Furthermore, TUNEL(Terminal deoxynucleotidyltransferase-mediated dUTP nick end labeling)and DNA fragmentation tests were performed to determine if GFJ is able to induce apoptosis in KB cells. Also a standard kit was used to assess caspase-3 activity in KB cells. Also western blotting was employed to evaluate the effect of GFJ on Bax:Bcl-2 ratio.Results. Significant cytotoxic effects were observed for the minimum used concentration (1μg/mL) as calculated to be 77.97±2.3% for 24 h and 818±3.1% for 36h of incubation (P < 0.001). Furthermore, TUNEL and DNA fragmentation tests corroborated the apoptosis inducing activity of GFJ. Consistently, after treating KB cells with GFJ(1μg/mL), caspase-3 activity and Bax:Bcl-2 ratio were raised by 7.3±0.6 and (P <0.001) folds, respectively.Conclusion. The results of this study advanced that GFJ induces apoptosis in the KB cells through increasing caspase-3 activity and Bax:Bcl2 ratio which could be attributed to its organo-sulfurcomponents.

IntroductionThe COVID 19 pandemic had a significant psychological impact worldwide. Health care workers (HCWs) were the most affected because of the pandemic burden and occupational exigencies.ObjectivesTo describe epidemiological characteristics of HCWs with post COVID19 anxiodepressive disorders.MethodsA descriptive cross-sectional study was carried out. It included HCWs of a university hospital who consulted the Occupational Medicine Clinics for the three-month post-COVID‘s medical visit. The study was carried out during the period March 2020 to January 2022. The data was collected using a questionnaire including socio-occupational and medical characteristics. Psychometric evaluation was carried out using « the Hospital Anxiety and Depression Scale »ResultsWe have collected 164 HCWs. The sex ratio (M/F) was 0.29. The average age was 41±9.8 years. They belonged to the pneumology (27%), intensive care (11%) and biology laboratory (11%). The prevalence of anxiety and depression was 34% and 30% respectively. We found an association between sleep disorders and anxiety (p=0.000), OR=5 IC95%[2.4-10.3] and depression (p=0.000), OR= 4 IC 95%[2.0-9.3]. We found an association between anxiety and persistent fatigue (p=0,000), OR=4[2,0-8,6], anxiety and concentration and memory difficulties (p=0,000), OR=3 IC 95%[1,7-6,9]. Referral to psychiatric consultations were done in 16% of the cases.ConclusionsPost-COVID anxiety disorders were frequent among HCWs and associated with neurocognitive disorders. Psychiatric support and early treatment are necessary to prevent mental deterioration.Disclosure of InterestNone Declared
