RESUMO
Com o aumento pela busca por procedimentos estéticos na Odontologia, o profissional busca alternativas para obter uma melhor previsibilidade dentro dos tratamentos cirúrgicos periodontais. O presente estudo buscou comparar a cicatrização após o recobrimento radicular, através da técnica de deslize coronal do retalho associado com o enxerto de tecido conjuntivo subepitelial, em uma região que recebeu a cirurgia e a aplicação de laser de baixa intensidade, em uma paciente com recessões RT1 de Cairo bilateral em maxila. O protocolo utilizado foi o de laser vermelho (660 nm) 30 J/cm² durante 30 segundos, 1,2 J por ponto, 40 mW, durante quatro dias. As regiões foram operadas em épocas diferentes e, portanto, acompanhadas clinicamente e fotografadas por um período entre um mês de pós-operatório até 26 meses. Clinicamente, foi possível concluir que a região que recebeu a terapia de fotobiomodulação pareceu ter uma melhor cicatrização e, consequentemente, ficou esteticamente mais favorável em um menor período quando comparada à região em que foi realizada apenas a cirurgia.
Palavras-chave – Autoenxerto; Gengiva; Laser; Cicatrização.
ABSTRACT
There is an increasing search for esthetic procedures in dentistry. Clinicians choose alternatives to increase predictability of periodontal surgical procedures, in order to obtain better esthetics. The present clinical case report compared wound healing in two sites in the same patient after root coverage with coronally advanced flap technique with subepithelial connective tissue graft. Both recessions were Cairo’s RT1 in maxilla premolars. One site received photobiomodulation with low intensity laser therapy: red laser (660 nm), 30 J/cm², 30 s, 1,2 J at each point, 40 mW, 4 days (48-hour interval). Wound healing was registered with photography during 26 months. The sites receiving photobiomodulation were better healed and it reached a better esthetics result in a shorter period compared to the non-irradiated site.
Key words – Connective tissue; Laser; Healing.
