Morphometric and morphologic evaluation of the mental foramen in relation to age and sex: an anatomic cone beam computed tomography study

Objective: The aim of this study was to assess the vertical and horizontal position, angle, and diameter of the mental foramen (MF) according to sex and age by cone beam computed tomography in a Turkish patient population. Methods: Cone beam computed tomography records of 192 consecutive patients consisting of 106 women and 86 men were examined, retrospectively. The vertical and horizontal positions of MF, angle and diameter of MF, and distance from MF to the alveolar crest and the base of the mandible were evaluated with respect to sex and age groups. Results: There were statistically significant differences in the distance of MF to the alveolar crest according to age groups. When we compared the right and left sides, we have only found out statistically significant differences in the angles of MF and that it was higher in the left side. Conclusions: From our results, the detection of the position of MF can provide detailed information for preoperative treatment planning (for surgery and dental implant surgery procedures), especially in the mandibular premolar region

Evaluation of enamel pearls by cone-beam computed tomography (CBCT)

Objective: The aim of this study was to evaluate the frequency of enamel pearls according to population, sex and tooth groups on Cone-Beam Computed Tomography (CBCT) or Dental Volumetric Tomography (DVT) scans of patients, retrospectively. Study Design: In this study, 15185 teeth belonging to 768 patients, 430 female and 338 male, was performed cross-sectional examination by CBCT. The volumetric Computed Tomography used in the study is Newton FP based on flat-panel. The data were analyzed with Pearson chi-squared test. Results: Enamel pearls were detected in 36 subjects (4.69%). Of these enamel pearls, 19 were detected in male and 17 were in male. There was no statistically a significant association between prevalence of enamel pearls and sex. All of enamel pearls were detected in molar teeth, for prevalence 0.83%. Conclusion: All of enamel pearls are found upper and lower molar teeth, especially the most commonly in maxillary second and third molars. © Medicina Oral S. L

Oral findings in children with celiac disease

Aim: To investigate whether Turkish children with celiac disease (CD) show dental enamel defects (DEDs), recurrent aphthous stomatitis (RAS), teeth missing, and xerostomia, and to compare the results with age- and sex-matched healthy children

Do children with Wilson's disease have distinct craniofacial morphology? A cephalometric study

WOS: 000322417900011PubMed ID: 23759337Objectives: Patients with Wilson's disease (WD) develop osseous changes such as osteoporosis, spontaneous fractures, areas of sclerosis and demineralization of maxillary and mandibular bones, and neurologic symptoms including swallowing dysfunctions, which may affect dento-facial growth. However, dento-maxillo-facial structures of these patients have never been investigated. The present study aimed to discover if subjects with WD have different dentofacial structures. Methods: Lateral cephalometric films of 13 children (5 males and 8 females) with WD and of 15 normal subjects (6 males and 9 females) were evaluated. Mean ages of the patients and controls were 12.62 +/- 3.09 years and 12.01 +/- 1.38 years, respectively. Lateral cephalometric cranial films of all subjects were taken in the same cephalostat in a habitual and unstrained body posture. Thirteen linear and 11 angular parameters were measured to describe the craniofacial characteristics of the subjects. Results: Statistical analysis showed that there is no statistically significant difference between parameters of normal children and children with WD, with the exception of palatal plane inclination. The inclination of palatal plane was higher in children with WD than in normal subjects. Conclusions: Children with WD and healthy children have approximately the same dento-maxillo-facial structures. However, increased palatal plane inclination may be a finding of WD
