Abstract(s)
Objetivo: avaliar a influência do tipo de incisão, utilizado na cirurgia de terceiros molares mandibulares, na incidência de complicações periodontais, nos segundos molares adjacentes.
Materiais e métodos: estudo prospetivo randomizado aberto, em pacientes com indicação de exodontia de terceiros molares mandibulares inclusos. Os 20 pacientes da amostra foram distribuídos de forma aleatória, onde 11 foram submetidos à remoção cirúrgica, utilizando uma incisão em envelope e os restantes 9 por meio de uma incisão trapezoidal. O preenchimento da informação relativa à identificação do paciente e às características da exodontia, foi realizado no dia da cirurgia, e a saúde periodontal dos segundos molares foi analisada no momento da exodontia (T0), oito dias (T1), um mês (T2) e três meses (T3) após a exodontia. Os parâmetros periodontais avaliados foram o índice de placa, o índice gengival, a profundidade de sondagem e o nível ósseo alveolar. Os dados recolhidos foram analisados através do software SPSS Statistics® v. 23.0.
Resultados: realizaram-se 20 exodontias em pacientes com uma média de idades de 21,20 ± 3,35 anos, 8 do sexo masculino e 12 do sexo feminino. Independentemente do tipo de incisão, o índice de placa, é, em média, significativamente inferior, em T3. Não foram encontrados resultados estatisticamente significativos entre as variáveis dependentes, índice de placa, índice gengival, profundidade de sondagem, e os dois tipos de incisão. No entanto, em T3, o nível ósseo alveolar é, em média, significativamente superior, quando utilizada a incisão trapezoidal (p=0,020).
Conclusão: não existem diferenças estatisticamente significativas entre o tipo de incisão e os parâmetros índice de placa, índice gengival e profundidade de sondagem. Por outro lado, a incisão trapezoidal está significativamente associada a um aumento da perda óssea alveolar, em distal do segundo molar adjacente.
Objective: the aim of this study was to evaluate the effect of flap design on the periodontal status of the second molar after lower third molar surgery. Materials and methods: prospective randomized open-label study, including patients with indication for included mandibular third molar extraction. The 20 patients in the sample were randomly assigned, 11 underwent surgical removal using an envelope flap and the remaining 9 patients with a trapezoidal flap. The information, corresponding to the patient's identification and the characteristics of the exodontia, was performed on the day of surgery, and the periodontal health of the second molars was analyzed at the time of extraction (T0), eight days (T1), one month T2) and three months (T3) after the extraction. The periodontal parameters evaluated were plaque index, gingival index, depth of probing and alveolar bone level. The data collected were analyzed using software SPSS Statistics® v. 23.0. Results: a total of 20 third molars were extracted. The mean patient age was 21.20 ± 3.35 years, 8 males and 12 females. Regardless of the type of incision, the plaque index is, on average, significantly lower in T3. No statistically significant results were found between the dependent variables, plaque index, gingival index, depth of probing, and the two types of incision. However, in T3, the alveolar bone level is, on average, significantly higher, when using the trapezoidal incision (p=0.020). Conclusion: there are no statistically significant differences between the type of incision and the parameters plaque index, gingival index and depth of probing. On the other hand, the trapezoidal incision is significantly associated with an increase in alveolar bone loss, distal to the adjacent second molar
