ABSTRACT
INTRODUCTION: Our aim in this study was to investigate the frequency, distribution, sex differences, and characteristics of supernumerary teeth in a referred Turkish population. METHODS: A total of 2599 patients' panoramic radiographs (1360 girls, 1239 boys) were evaluated, including children in both the mixed and the permanent dentitions. Their mean age was 8.6 +/- 0.23 years. Number, location, classification, side, and impaction of supernumerary teeth were evaluated. Furthermore, the development of these teeth was evaluated. RESULTS: Eighty-four supernumerary teeth were found on 69 radiographs; 9 were deciduous and 75 were permanent teeth. Most supernumerary teeth were in the premaxillary region (67%). Mesiodens (n = 43) was the most frequent supernumerary tooth (51.2%). This was followed by the maxillary lateral incisor (15.5%), the mandibular premolar (14.3%), the maxillary canine (9.5%), the maxillary premolar (6%), the mandibular lateral incisor (2.4%), and the mandibular canine (1.2%). Sixty-two (73.8%) supernumerary teeth were impacted. The male-female ratio was 1.13:1, which was not statistically significant. CONCLUSIONS: The prevalence of supernumerary teeth in Turkish children was 2.7% in this study.

OBJECTIVE: To determine the most appropriate oral hygiene motivation method (OHMM) for orthodontic patients with fixed appliances. MATERIALS AND METHODS: A total of 150 orthodontic patients, scheduled for their regular controls, were included in this study. The patients were divided into five groups (n = 30) according to the verbal OHMM and instructed as follows: only verbal information (V), verbal information with demonstration on model (M), verbal information with demonstration on model and self application by the patient (M+A), verbal information using the illustration catalog (I), and verbal information using the illustration catalog and self application by the patient (I+A). All of the applications of the patients were made under the supervision of the clinicians. The periodontal parameters (plaque index [PI], gingival index [GI], and bleeding on probing [BOP]) were recorded at the baseline (before the instructions of the OHMM), 1 week later, and 4 weeks after the OHMM. RESULTS: All periodontal parameters showed significant decreases after 4 weeks in all OHMM groups (P < .05). I+A group has significantly lower PI scores and BOP percentages than the other groups (P < .05) after 4 weeks. The difference between the V group and M+A, I, and I+A groups in the GI scores were significant (P < .05), and the I+A group has presented the lowest GI score. CONCLUSIONS: The OHMM applied by the patients under the supervision of the clinician seemed to be more successful in the elimination of plaque and inflammatory symptoms in patients with fixed appliances.

Pseudoxanthoma elasticum (PXE) is an inherited disorder that has both autosomal recessive and autosomal dominant pathways and is characterized by severe malformation of elastic and collagen fibers. Clinically, 3 main groups of systemic findings involving skin, eye, and vessels emerge in the symptoms. In this report, we present the case of a patient with PXE who has agenesis of most of the permanent teeth. No previous reports in the English literature have mentioned oligodontia in PXE. Our treatment plan consisted of extraction of the upper left deciduous canine followed by fixed orthodontic treatment. Further prosthodontic rehabilitation was planned to restore the edentulous area.
