Resumo
A exodontia de terceiros molares inferiores é uma prática comum nas clínicas odontológicas, porém o pós-operatório inerente a esta cirurgia apresenta dor, edema e trismo. Algumas das posições de inclusão do terceiro molar podem acarretar comprometimento periodontal nos segundos molares adjacentes. Com isso o presente trabalho buscou desenvolver através deste estudo clínico controlado, um protocolo com o laser de baixa intensidade para aplicação no pós-operatório das exodontias de terceiros molares mandibulares, de modo a minimizar os sinais e sintomas e melhorar os parâmetros periodontais dos segundos molares adjacentes. O laser empregado foi o Photon Laser III – DMC, São Carlos, SP/Brasil – como meio de condução o vermelho, com comprimento de onda 660 nm, potência útil de 30 mW, meio ativo AsGaAl. Sessenta pacientes de ambos os gêneros, com necessidade de exodontia dos terceiros molares, em classificações padrões de posição, foram randomizados em três grupos para análise – Grupo I: 10J/cm2, Grupo II: 30J/cm2 e Grupo III: Sham, e acompanhados pelo período de 6 meses. A análise do trismo e edema facial no pós-operatório e do nível clínico de inserção encontraram diferenças estatísticas significantes entre os grupos que receberam a terapia laser quando comparado ao grupo sham. Portanto, a utilização do laser de baixa intensidade como terapia adjuvante após a exodontia de terceiros molares demonstrou efetividade. Sendo que o Grupo I se destacou, após seis meses de avaliação.
The extraction of lower third molars is a common practice in dental clinics, but the postoperative period inherent to this surgery presents pain, edema and trismus. Some of the inclusion positions of the third molar can lead to periodontal involvement in the adjacent second molars. The aim of this study was to develop a low-intensity laser protocol for the post-operative treatment of mandibular third molar extractions in order to minimize the signs and symptoms and to improve the periodontal parameters of the second molars adjacent. The laser used was Photon Laser III - DMC, São Carlos, SP / Brazil - as red conduction medium, with wavelength 660 nm, useful power of 30 mW, active medium AsGaAl. Sixty patients of both genders, in need of third molar extraction in standard position classification, were randomized into three groups for analysis - Group I: 10J / cm2, Group II: 30J / cm2 and Group III: Sham, and monitored for the period of 6 months. The analysis of trismus and facial edema in the postoperative and the clinical level of insertion found significant statistical differences between the groups that received the laser therapy when compared to the sham group. Therefore, the use of the low intensity laser as an adjuvant therapy after third molar extraction was effective. As Group I stood out after six months of evaluation.
