Objective. To evaluate characteristics of smile related to visibility in individuals with cleft lip, alveolus, and palate. Design. Cross-sectional. Setting. HRAC/USP, Brazil. Patients. Individuals with repaired complete unilateral cleft lip and palate (n = 45), aged 15–30 years. Interventions. Frontal facial photographs were obtained in natural and forced smiles (n = 135). Six specialists in periodontics evaluated the photographs as to the smile line, thickness, and curve of the upper lip. Main Outcome Measures. The cleft area was compared with the contralateral region. Results were expressed as percentages and means. The findings were compared between groups of periodontists. Results. Statistically significant relationship was observed in the smile line between examiners and between natural and forced smiles, regardless of the association with the cleft side. The lip was thicker at rest and thinner in the forced smile, as also evaluated by the group not experienced with cleft care. The curve of the upper lip in natural and forced smiles was considered as close to straight by both groups, regardless of the cleft. Conclusion. The smile in individuals with clefts was regarded as average for both cleft and noncleft sides. The thickness was characterized as average to thin, being thinner in forced smile and when analyzed by the group not experienced with cleft care. In the average, the curve of the upper lip was considered as straight. The present study elucidates some characteristics related to the smile in individuals with repaired unilateral cleft lip, alveolus, and palate.

OBJECTIVE : To clinically evaluate the effects of diode laser, Gallium-Aluminum-Arsenide laser (GaAlAs), on the pain and edema after secondary alveolar bone graft. DESIGN : Case-control, double-blind study. Setting : Institutional tertiary referral hospital. Participants : The sample was composed of 60 individuals with complete unilateral cleft lip and palate, of both genders, aged 9 to 15 years, submitted to secondary alveolar bone graft. MAIN OUTCOME MEASURES : The individuals were divided into an experimental group (patients irradiated with diode laser GaAlAs, energy density of 4 J/cm(2), power of 100 mW, and wavelength in the infrared spectrum, for 10 seconds per point on 10 points, adding up to a dose of 40 J/cm(2)) and a placebo group (simulated laser application for 60 seconds per point, also on 10 points). Applications were made on the receptor site immediately postoperatively and after 24 and 48 hours. The pain and edema were assessed preoperatively and at each application. RESULTS : The two groups presented increase in pain and edema in 24 and 48 hours. No statistically significant difference was found between groups. CONCLUSIONS : According to the present methodology, the use of low-level laser to control the pain and edema in the postoperative period of secondary alveolar bone graft was not effective.

Resumo 60 ratos machos (Rattusnorvegicus, albinus, Wistar), receberam ligadura de algodão na região subgengival de um dos primeiros molares inferiores (lado teste) para indução da doença periodontal experimental. O primeiro molar contra-lateral foi utilizado como controle (boca dividida) Após os períodos de 3, 7, 14 e 21 dias de indução da doença periodontal, 40 animais foram eutanizados, e as amostras de 10 animais por período foram fixadas e submetidas ao procedimento histológico de rotina para avaliação histométrica e ensaio de imunohistoquímica para os marcadores de fenótipo mesenquimal indiferenciado (CD146, CD105 e CD166). Os mesmos ensaios foram realizados em outros 20 animais que receberam tratamento periodontal básico após 21 dias de indução da doença. Esses animais foram eutanasiados 3 (n=15) e 7 (n=15) dias pós-tratamento para realização de análise histométrica e imunohistoquímica.
