Abstract AIMS: This case-control study was conducted to analyze the association of periodontitis with risk predictors i.e. education status, brushing habits and past dental visits in systemically healthy patients. MATERIALS AND METHODS: A total of 1097 systemically healthy, non-tobacco using patients with age ≥18 years who reported to periodontology department were included. The demographic details and dental care pattern of the patients were extracted from the records of periodontology department and their frequencies were formulated. The association of three predicting factors i.e. education status, brushing habits and past dental visits was assessed on SPSS using binary logistic regression analysis. RESULTS: A total of 471(42.9%) patients were diagnosed with periodontitis. Higher frequency of periodontitis was observed in patients who were male and >50 years of age. Subjects with ≥ 12 years of education, regular brushing habits and regular past dental visits showed greater odds of being safe from periodontitis. CONCLUSIONS: A positive association between the study variables and periodontitis was observed, which will help the clinicians in prediction of periodontitis in systemically healthy, non-smoking individuals. It also indicates a need of tailor made dental educational and awareness programs for prevention and control of periodontitis in systemically healthy individuals.

Aim: This case-control study was conducted to analyze the association of periodontitis with risk predictors i.e. age, gender, education status, brushing habits and past dental visits in systemically healthy patients. Materials and Methods: The study included total of 1097 systemically healthy, non-tobacco using patients with age ≥ 18 years that reported to periodontology department from year 2018. The demographic details and dental care pattern of the patients were extracted from the records of periodontology department, and their frequencies were formulated. The association of five study variables i.e. age, gender, education status, brushing habits and past dental visits was assessed using forward step-wise logistic regression analysis. Results: Total of 471(42.9%) patients were diagnosed with periodontitis. Higher frequency of periodontitis was observed in patients who were male and ≥ 50 years of age. Regression analysis showed that the subjects with < 50 years of age, ≥ 12 years of education, regular brushing habits and regular past dental visits had greater odds of being safe from periodontitis. Conclusion: Since the population chosen for this research was systemically healthy, non-tobacco using individuals, a high prevalence (42.9%) of periodontitis was observed indicating the need to analyze the factors other than systemic conditions contributing in prevalence of periodontitis. Furthermore, a positive association between study variables and periodontitis was observed in this research, which will help the clinicians in prediction of periodontitis in systemically healthy, non-tobacco using individuals.

AbstractA case-control study was conducted to evaluate the association between maternal age and parity and dizygotic (DZ) and monozygotic (MZ) twinning, respectively. Mothers of all twins born alive in Denmark in 1984 or 1985 were included into the study as cases, and a random sample of mothers of singletons were controls. Data on maternal age at delivery and number of previous births were collected from the Danish Medical Birth Register. By means of logistic regression analysis, a significant and positive association was found betwen maternal age and DZ twinning, and a significant and negative association between parity and MZ twinning. No association was found for parity and DZ twinning, nor for maternal age and MZ twinning. The study suggests that human MZ twinning has predictors too, as has DZ twinning. The finding has implications for zygosity classification in future twin research.

The aim of this retrospective case-control study is to determine a possible correlation between breathing mode and craniofacial morphology. The study was carried out in the Department of Pedodontics,Iuliu Hatieganu University of Medicine and Pharmacy, Cluj-Napoca, Romania. The sample comprised 80 patients, age between 6 and 13 years, which were divided in two groups based on respiratory pattern: control group composed of 38 nasal breathing children and case group composed of 42 oral breathing children. Three quantitative craniofacial parameters were measured from the frontal and lateral photos: facial index, lower facial height ratio and upper lip ratio. The statistical analysis showed a significant higher facial index (p=0.006*) and an increase lower facial height (p=0.033*) for the oral breathers group. No differences in facial morphology were found between genders and age groups, when comparing the data between the same type of respiratory pattern children. Spearman�s rho Correlation show a significant positive correlation (p=0.002*) between facial index and lower facial height and a significant negative correlation between facial index and upper lip (p=0,005*). Long faces children are more likely to develop oral breathing in certain conditions, which subsequently have a negative effect on increasing the lower facial height by altering the postural behavior of mandible and tongue.
