Objetivo: Avaliar se um colutório com triclosan (Bexident Gengivas) apresenta vantagens clínicas relativamente a um placebo na fase de suporte do tratamento periodontal. Materiais e métodos: Foi realizado um estudo piloto em 14 pacientes em fase de manutenção da terapia periodontal. Os pacientes foram aleatoriamente distribuídos por dois grupos (Bexident GengivasÒ e placebo), tendo sido avaliados numa consulta inicial e 3 meses após a utilização bi-diária do produto. Os parâmetros analisados foram placa bacteriana, hemorragia gengival, hemorragia à sondagem, profundidade de sondagem, posição da margem gengival e perda de inserção. A análise estatística foi realizada através de testes não paramétricos, recorrendo à base de dados SPSS (IBM Statistics v.24, SPSS Inc, Chicago, IL). Resultados: O Índice Percentual de Placa Simplificado diminuiu no grupo de teste 7,885% (p=0,428) e no grupo de controlo 2% (p=0,8339). O Índice Gengival Simplificado diminuiu no grupo de teste 2,015% (p=0,604) e no grupo de controlo 3,036% (p=248,00). O Índice Percentual de Hemorragia diminuiu no grupo de teste 3,314% (p=0,575) e aumentou no grupo de controlo 0,261% (p=0,955). Para o grupo de teste, o valor médio de profundidade de sondagem (PS) (p=0,121) e de perda de inserção (PI) (p=0,796) diminuíram. O valor médio de recessão gengival (RG) aumentou (p=0,200). No grupo de controlo, o valor médio de PS (p=0,286) e RG (p=0,525) diminuíram. A inserção periodontal aumentou 0,2343mm (p=0,485). A distribuição de localizações segundo a PI manteve-se estável no grupo de controlo. No grupo de teste, as localizações com perda de inserção menos severa aumentaram, não significativamente. Para o dente que inicialmente apresentava maior PS, o grupo de teste apresentou menos variações. Não existiram diferenças estatisticamente significativas entre grupos. Conclusão: A utilização bi-diária de um colutório com triclosan durante um período de 3 meses não trouxe vantagem clínica à terapia de manutenção periodontal.
Objetive: Evaluate if a mouthrinse containing triclosan (Benxident Gengivas) has clinical advantages in relation to a placebo rinse in the maintenance phase of periodontal therapy. Materials and methods: A pilot study was conducted in 14 patients in the maintenance phase of periodontal therapy. The patients were allocated to one of two groups (Bexident GengivasÒ and placebo) and were evaluated initially and 3 months after rinsing with the designated product twice a day. The observed parameters were, plaque, gingival bleeding, bleeding on probing, pocket depth, position of the gingival margin and loss of attachment. The statistical analysis was performed with non-parametric test and the SPSS database (IBM Statistics v.24, SPSS Inc, Chicago, IL). Results: The Simplified Plaque Index decreased in the test group 7,885% (p= 0.428) and 2% (p= 0.8339) in the control group. The Simplified Gingival Index decreased in the test group 2,015% (p= 0.604) and 3,036% (p= 248.00) in the control group. The Bleeding on Probing decreased in the test group 3,314% (p= 0.575) and increased 0,261% (p= 0.955) in the control group. For the test group, the mean value of probing depth (PD) (p= 0.121) and attachment loss (AL) (p= 0.796) decreased. The mean gingival recession (GR) value increased (p= 0.200). In the control group, mean PD (p= 0.286) and GR (p= 0.525) decreased. Periodontal attachment increased 0.2343mm (p= 0.485). The distribution of locations according to AL remained stable for the control group. In the test group, there was a non-significant increase in the locations with less severe attachment loss. For the tooth that initially presented higher PS, the test group presented less variations. There were no statistically significant differences between groups. Conclusion: Rinsing twice a day with a mouthwash containing triclosan for 3 months did not bring any clinical advantage to periodontal supportive care.
