CBCT detected more cases of PIR than panoramic radiography. The mandibular third permanent molar was the most commonly affected tooth.

The MSVs of the UCLP patients showed a statistically significant decrease compared to those of the controls ( P < .001). There was also a significant difference in the MSVs of the cleft and noncleft sides of the UCLP patients ( P < .05).

CBCT can be useful for diagnosing PIR defects because it provides an accurate representation of internal dental anatomy. SCANNING 38:442-447, 2016. © 2016 Wiley Periodicals, Inc.

The aim of this study was to investigate whether or not the Nolla method is appropriate for Turkish children for the determination of the dental age (DA). A group of 719 children between the ages of 6 and 18 years were included in the study. DAs from orthopantograms by the Nolla method were estimated. The results obtained were compared with chronologic age (CA). Paired t and the Wilcoxon tests were performed. Both genders were underestimated in dental maturity when compared with the reference samples in total (-0.3 years) (p<0.01). The differences in girls were statistically significant in total and in all groups except for 7-7.9. The differences in boys between the CAs and DAs were not statistically significant in total and in all groups except for 7-7.9 and 8-8.9. Although the accuracy of this method was suitable for boys, according to our findings, it was not suitable for girls.

The results of this study showed that DA of patients with sagittal skeletal malocclusions was approximately twice more advanced when compared with patients without sagittal skeletal anomaly patterns.

The aim of this study was to investigate whether or not the Greulich-Pyle (GP) method is adequate for Turkish children. A group of 767 individuals (425 girls and 342 boys) between 7 and 17 years were studied. Bone age (BA) from plain radiographs of left hands and wrists by GP standards was estimated. The total mean differences between BA and chronological age (CA) for girls and boys were found to be 0.20 and -0.13 years, respectively. There were significant differences between BA and CA in age groups 7-, 8-, 10-, 11-, 12-, 13-, 15-, and 16-year-olds for girls and 7-, 10-, and 12-year-olds for boys. The results of this study suggest that the mean differences between BA and CA are low enough to be of no practical significance, and thus, for the time being unless any other methods will be proved more useful, this method could be used in all age groups.

Objective:To isolate Helicobacter pylori (HP) from the dental plaque of a selected group of children and to compare the oral and salivary findings of patients with those of a healthy control group.Methods:A total of 70 children aged 5–15 years were included in this study. An intraoral examination was performed for each patient, and dental plaque and saliva specimens were collected for analysis. Oral health conditions, nutritional habits, tooth brushing frequency, saliva pH levels, flow velocity, and buffering capacities were noted. The Kruskal–Wallis test was used for comparison of the DMFT and dft index. The significance level was set at p=0.05.Results:The prevalence of HP in dental plaque was higher in study group than controls (p<0.05). There were no significant differences between groups with respect to DMFT and dft scores, nutritional habits, tooth brushing frequency, saliva pH level or flow velocity (p>0.05). Meanwhile, the buffering capacity of saliva was lower in HP gastritis patients (p<0.05).Conclusion:There was a high prevalence of HP in dental plaque; thus, the oral cavity may be an important reservoir for HP. Good oral hygiene could be a positive contributor to the treatment of gastritis.
