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.

Objective To determine whether there is a relationship between congenitally bilaterally absent maxillary lateral incisors (BAMLIs) and skeletal anomalies and/or normal variants. Materials and Methods The records of 86 patients (62 girls, 24 boys; age 12–17 years) with congenitally BAMLIs and 86 patients (55 girls, 34 boys; age 13–18 years) without any dental or skeletal anomalies were collected and evaluated retrospectively. The study was based on the evaluation of lateral cephalometric and orthopantomographic radiographs. Posterior arch deficiency of the atlas bone (PADA); atlanto-occipital ligament calcification, known as “ponticulus posticus” (PP); and interclinoid ligament calcification, known as “sella turcica bridging” were recorded for each participant. Pearson χ2 and Fisher exact tests were used to evaluate and compare skeletal anomalies and/or normal variants between patients with BAMLIs and the control group. Results The prevalence of cervicovertebral anomalies and/or normal variants seen in the lateral cephalometric radiographs was higher in patients with BAMLI than in the control group. The prevalence of PP was lower and that of PADA was higher in patients with BAMLIs than in the control group (P < .05). Conclusion The prevalence of PADA was increased and that of PP formation was decreased in patients with BAMLIs. There was a significant relationship between skeletal anomalies and/or normal variants.
