Effect of dental visit frequency on dental caries experience and oral health factors in schoolchildrenBackground: The present study determined the effect of dental visit frequency on dental caries experience and oral health factors in schoolchildren.Methods: This study was carried out on 188 adolescents (14-16 years old) of both gender who attending Selcuk University Faculty of Dentistry in Konya, Turkey. Mean DMFT (decay, missing and filling tooth) , plaque and gingival index scores were identified for every indivudual. The WHO (World Health Organization) criteria and bitewing radiographs were utilized to diagnose the carious status of the subjects. Data on age, gender, dental visit frequency, oral health habits, parental educational status and mean family income were collected by a questionnaire completed by the subjects. Subjects were divided into two groups according to dental visit frequency (regular and irregular) after recording all data. Chi-square test was used for statistical analyze.Results: The sample consisted of 47 subjects for regular and 141 for irregular group, respectively. The significant association was found with dental visit frequency and age of first dental visit (p<0.001), mean caries (p<0.001) and filling (p=0,029) teeth, plaque index (p=0,005), toothbrushing frequency (p=0,004) and brushing before bedtime (p=0,013). There were no significant association with dental visit frequency and gender (p=0,308), mean missing teeth (p=0,421), mean DMFT (p=0,183), gingival index (p=0,05), usage dental floss (p=0,101) and mouthwash (p=0,155), mother (p=0,084) and father (p=0,489) educational level and mean family income (p=0,768). Conclusion:It is tought to regular dental visit is extremely important for children's oral care and in terms of reducing the overall caries risk.

Background: The mandible, the largest and strongest bone in the face, is the only bone in the skull that does not have a sutural joint. Before starting surgical procedures and clinical approaches, it is necessary to know the anatomy of this region well. Materials and methods: It is a radiology-based morphometric study in which retrospectively scanned images of adult individuals in the 20-50 age range, whose results are normally reported using CT (Conical Beam Computed Tomography) {n=212}. Tomographic images, photographed with Planmeca ProMax3DMid ProFace brand CBCT device, was examined using the Planmeca Romexis 4.6.2.R licensed program. Mandibular incisure angle and gonial angle of the mandible were measured from those images. Gender and age-related comparisons were performed. Results: In all groups, the relationship between the right incisure angle and the right gonial angle was determined as a weak positive relationship, but was found to be statistically significant. The Gonial angle is larger in females on both sides of the jaw than in males. In the study of changes in correlation between mandibular incisure and gonial angle depending on age groups, a statistically significant positive correlation was found in the group that we can call young adults, while a significant difference was not observed in the middle age group and the group that we can call old age. Conclusions: Age and gender-based reference values of gonial angle of mandible and mandibular incisure angle were determined. It is the first study in the literature in which the size and shape of the Incisure angle is evaluated on a cross-population and gender basis. We believe that these angles will have many benefits from a clinical point of view.
