Resumo
Introdução: A morbilidade associada à zona dadora de enxertos de tecido conjuntivo é um dos principais problemas na cirurgia de recobrimento radicular. Recentemente, as membranas de L-PRF têm sido aplicadas na zona dadora, de forma a acelerar a cicatrização e melhorar o pós-operatório.
Objetivo: O objetivo deste estudo é avaliar clinicamente o efeito do L-PRF na cicatrização do palato e nível de dor pós-operatória.
Materiais e Métodos: Este estudo contou com a participação de 18 pacientes com recessões gengivais, indicados para cirurgia de recobrimento radicular. Os pacientes foram distribuídos de forma aleatória em 2 grupos: O grupo controlo (com esponja hemostática no palato), composto por 6 participantes e o grupo de estudo (L-PRF no palato), constituído por 12 participantes. Após a cirurgia foram realizadas consultas de
follow-up ao 7º, 14º e ao 21º dia após a cirurgia. Os parâmetros avaliados nessas consultas foram: complicações pós-operatórias; qualidade do encerramento da ferida cirúrgica; nível de dor e consumo de analgésicos;
Resultados: No grupo de estudo houve uma maior redução da deiscência da ferida cirúrgica ao longo de T1, T2 e T3 (p 0,05) comparativamente ao grupo controlo.
Relativamente à dor, não se observaram diferenças estatisticamente significativas entre os dois grupos em T1 e T2, no entanto em T3 (p= 0,04) os resultados demostraram uma diminuição estatisticamente significativa da dor percecionada pelos pacientes do grupo de estudo. Os participantes do grupo de controlo relataram um maior consumo de analgésicos durante o período pós-operatório comparativamente ao grupo de estudo.
Conclusão: Tendo em conta os resultados e as limitações deste estudo, conclui-se que a utilização da membrana de L-PRF no palato pode afetar positivamente a cicatrização e reduz a morbilidade pós-operatória.
Introduction: Morbidity associated with the donor zone of connective tissue grafts is one of the main problems in root coverage surgery. Recently, L-PRF membranes have been applied to the donor zone in order to accelerate healing and improve the post-operative period. Aim: The aim of this study was to clinically evaluate the effect of L-PRF on palatal healing and post-operative pain levels. Materials and Methods: This study involved 18 patients with gingival recessions indicated for root coverage surgery. The patients were randomly assigned to 2 groups: the control group (with haemostatic sponge on the palate), made up of 6 participants, and the study group (L-PRF on the palate), made up of 12 participants. Follow-up appointments were held on the 7th, 14th and 21st days after surgery. The parameters assessed at these visits were: post-operative complications; quality of surgical wound closure; level of pain and consumption of analgesics. Results: Palate dehiscence was analysed in terms of length, width and height and it was found that in the study group there was a greater reduction in surgical wound dehiscence over T1, T2 and T3 (p 0.05) compared to the study group. With regard to pain, statistically there were no differences between the two groups at T1 and T2, however at T3 (p= 0.04) the results showed a statistically significant reduction in the pain perceived by patients in the study group. Participants in the control group reported higher consumption of analgesics during the post-operative period compared to the study group. Conclusion: Taking into account the results and limitations of this study, it is concluded that the use of L-PRF membrane on the palate improves postoperative morbidity.
