Abstract Treatment of oral vascular anomalies (OVA) has focused on minimally invasive techniques rather than radical surgery. We investigated the efficacy and safety of diode laser using the photocoagulation technique in the management of OVA. Forty-seven subjects with OVA were treated with forced dehydration with induced photocoagulation (FDIP) using diode laser (808 nm/4.5 W). This series consisted mostly of male (63.8%) and non-white (63.8%) patients with a mean age of 57.4 years. Varices (91.5%), venous malformations (6.4%), and hemangiomas (2.1%) with a mean size of 7.1 (±4.9) mm were the conditions treated. OVA presented as a nodular lesion (63.8%) involving mainly the lower lip (46.8%). Pulsed laser mode was used as standard and the number of applications varied from one to four sessions, with the majority requiring only one (83%) FDIP session. Kaplan-Meier analysis revealed that complete clinical healing can occur on the 15th day (n=9/29.5%), followed by the 20th (n=6/45.5%), and 30th (n=7/70.5%) days. Postoperative edema was observed in 31 (66%) patients, and recurrence of the lesion occurred in two (4.2%). Based on the data on complete clinical healing, minimal patient discomfort, and satisfactory esthetic results, we can confirm that FDIP by diode laser is a promising candidate for the safe and efficacious treatment of OVA.

RESUMO A displasia cemento-óssea florida é um subtipo de lesão fibro-óssea que geralmente aparece nos ossos gnáticos de mulheres negras de meia idade. Clinicamente a displasia cemento-óssea florida é assintomática. Os aspectos radiográficos mostram uma área radiolucente com várias massas de estruturas radiopacas, tipicamente encontradas próximas às raízes dos dentes. O tratamento é requerido quando ocorre infecção devido à exposição da lesão na cavidade oral. Em casos mais severos, dor e deformidade podem estar presentes. Concomitante a higiene oral, visitas de rotina ao dentista são recomendadas ao indivíduo afetado. O objetivo deste estudo foi apresentar o caso clínico de uma mulher de 24 anos de idade, cor da pele branca com diagnóstico de displasia cemento-óssea florida com acompanhamento de 13 anos. Algumas alterações no padrão radiográfico foram observadas, como a mineralização progressiva da lesão. Tratamento ortodôntico foi realizado em um serviço privado. Não foi realizado exodontia. Esta alteração era esperada, pois a displasia cemento-óssea florida tem diferentes estágios de desenvolvimento. É sugerido, portanto, que a presença da displasia cemento-óssea florida não impediu o sucesso do tratamento ortodôntico.

ABSTRACT Florid cemento-osseous dysplasia is a subtype of fibrous-osseous lesion that commonly appears in the jaws of middle-aged black women. Clinically, the florid cemento-osseous dysplasia is asymptomatic. The radiographic aspect shows a radiolucent area with several masses of radiopaque structures, typically found in the toothbearing areas. Usually, the diagnosis is made during routine radiographic examination. The treatment is required when infection occurs due to exposure of the lesion in the oral cavity. In these severe cases, pain and facial deformity may be present. Commitment oral hygiene and routine dental visits for check-up are recommended for individuals affected. The objective of this study was to present a clinical case of a 24-year-old white woman with florid cemento-osseous dysplasia, who had been under surveillance for 13 years. Some changes in the radiographic pattern were observed as the orthodontic treatment was carried out in a private service. No tooth extraction was performed. This change is expected because florid cemento-osseous dysplasia has different radiographic aspects that correspond to the different developmental stages of the lesion. It is suggested, however, that the presence of florid cemento-osseous dysplasia did not preclude the success of the orthodontic treatment.

Abstract The aim of this study was to investigate the prevalence of oral and maxillofacial lesions among children from representative regions of Brazil. A retrospective descriptive study was conducted. Biopsy records comprising the period from 2000 to 2015 were obtained from the archives of three Brazilian oral pathology referral centers. A total of 32,506 biopsy specimens were analyzed, and specimens from 1,706 children aged 0–12 years were selected. Gender, age, anatomical location and histopathological diagnosis were evaluated. Descriptive statistics was carried out. Likelihood ratio tests were used to evaluate the association between the categorical variables. The level of significance was set at 0.05. The post-hoc test was used to identify the subgroups that significantly differed from one another, and the Bonferroni correction was applied. A total of 1,706 oral and maxillofacial lesions were diagnosed in pediatric patients, including 51.9% girls. Oral mucocele was the most prevalent reactive/inflammatory lesion (64%). The most commonly affected sites were the lips (34.5%) and mandible (19.9%). A significant association was observed between age and the group of lesions of the oral cavity (p < 0.001), and between age and anatomical location (p < 0.001). Pediatric oral and maxillofacial lesions were frequent and showed wide diversity, with the prevalence of mucocele. Knowledge of oral lesions is important for pediatric dentists worldwide, since it provides accurate data for the diagnosis and oral health of children.
