Effect of molar root fusion on radiographic bone loss

The aim of this investigation was to verify if there was an association between root fusion in molars and radiographic interproximal bone loss. Intra-oral radiographs of 810 molars from 102 subjects were obtained. All radiographs were taken by the same operator under standardized conditions. A 0.5 cm orthodontic wire was fixed tho the film to allow correction for distortion. Fused molars (FM) were compared to non-fused molars (NFM) with regard to the root length, the distance from the cementum-enamel junction to the alveolar bone crest and the bone loss percentage. The measurements were performed by two calibrated investigators. The prevalence of root fusion was 18.64%. Fifty-nine individuals (57.8%) presented at least one fused molar, which was compared to NFM from the same individuals. There was no significant difference between fused and non-fused molars according to the mean root length, the distance from cementum-enamel junction to alveolar bone crest and the bone loss percentage. The authors concluded that molars with radiographic evidence for root fusion do not exhibit more interproximal bone loss than NFM

Lesão de células granulares congênita: relato de caso / Congenital granular cell lesion: a case report

A lesão de células granulares congênitas ou epúlide congênita é uma lesão rara, que acomete recém-nascidos (RN) e ocorre predominantemente no rebordo alveolar superior. Essa lesão apresenta comportamento benigno, e não há relatos na literatura de recidiva. Nós descrevemos o caso de uma RN de ciinco dias de vida, apresentando lesão na mucosa gengival mandibular com dificuldades para alimentação. O tratamento realizado constou de uma excisão cirúrgica sob anestesia geral, e o exame histológico mostrou presença de células granulares.

Congenital granular cell lesion, or congenital epulis, is a rare lesion occurring in the newborn and arising predominantly from the maxillary alveolar ridge. It presents a bening behavior and no cases of recurrence have been reported. We report the case of a girl aged five days, who presented with a large mass arising in the gengival mucosa of the mandible, causing difficulty in feeding. The treatment was a surgical excision under general anesthesia and histological examination revealed large granular cells.

Tratamento cirúrgico da macroglossia: relato de 2 casos / Surgical management of macroglossia: discussion of 2 cases

Macroglossia é uma doença de etiologia múltipla, classificada como verdadeira ou relativa, podendo ser congênita ou adquirida. A redução cirúrgica da língua é um procedimento incomum, indicado para correção de alterações funcionais ou estéticas. Pode estar associada à mordida aberta anterior, à protrusão bimaxilar e à instabilidade no tratamento ortodôntico e ortodôntico-cirúrgico. Neste artigo, são descritos dois casos de deformidade dentofacial e má oclusão classe III de Angle associada à macroglossia relativa, submetidos à cirurgia ortognática e glossectomia parcial.

Congenital or acquired macroglossia - the abnormal enlargement of the tongue - is a pathological condition of multiple etiology, and may be classified as acquired or congenital. Surgical reduction of the tongue is an uncommon procedure that, however, may be required for functional and aesthetic reasons. Enlarged tongue is thought to be an etiological factor in anterior open bite, bimaxillary protrusion, and instability after orthodontic and orthodontic-cum-surgical treatment. This article describes two patients with dentofacial deformities and Angle Class III malocclusion associated with relative macroglossia, treated with orthognathic surgery and partial glossectomy.
