Efeito de um colutório contendo chá verde e ácido hialurônico sobre a saúde peri-implantar

RESUMO

O objetivo desse estudo foi avaliar um colutório à base de chá verde e de ácido hialurônico em pacientes portadores de próteses do tipo protocolo superior ou inferior com pelo menos seis meses em função. Dos 20 pacientes envolvidos no estudo, 17 finalizaram o acompanhamento de dois meses (15 mulheres e dois homens), sendo que nove utilizaram o colutório-teste e oito utilizaram o colutório-controle. Esses pacientes apresentaram 112 implantes no total, sendo que sete apresentaram próteses protocolos superiores, sete apresentaram próteses protocolos inferiores e três apresentaram próteses protocolos superiores e inferiores. Foram analisados quatro sítios por implantes (mesial, vestibular, distal e palatino-lingual) no período baseline e após 60 dias do início da utilização dos colutórios: 1) Profundidade de sondagem (PS); 2) Nível da margem peri-implantar (NMP); 3) Nível clínico de inserção (NCI); 4) Índice de inflamação (II); e 5) Índice de biofilme (IB). Os pacientes apresentavam inflamação peri-implantar e má condição de higiene oral no início do estudo, e todos os pacientes apresentaram redução no IB e II. Os pacientes que utilizaram o colutório-teste apresentaram redução da inflamação em relação aos pacientes que utilizaram o colutório-controle no período de 60 dias. O colutório à base de chá verde e ácido hialurônico promoveu redução da inflamação, que foi associada à redução da quantidade de biofilme em pacientes com próteses totais suportadas por implantes dentários.

Palavras-chave – Biofilme oral; Controle químico; Implantes dentários; Inflamação.

ABSTRACT

The objective of this study was to evaluate a mouthwash based on green tea and hyaluronic acid in patients with complete, arch fixed implant-supported prostheses with at least 6 months in function. Of the 20 patients involved in the study, 17 completed the 2-month follow-up (15 women and 2 men), with 9 using the test mouthwash and 8 using the control mouthwash. These patients presented a total of 112 implants, with 7 patients having upper total arch prostheses, 7 patients with lower total arch prostheses and 3 patients with upper and lower total arch prostheses. Four implant sites were analyzed (mesial, buccal, distal and palatine-lingual) at baseline and after 60 days after the beginning of the mouthwash use: 1) Probing depth (PD); 2) Peri-implant margin level (PML); 3) Clinical attachment level (CAL); 4) Inflammation index (II); and 5) Biofilm index (BI). Patients presented peri-implant inflammation and poor oral hygiene at baseline, and all patients had a reduction in IB and II at the 60-day period of follow-up. Patients who used the test mouthwash showed reduced inflammation compared to patients who used the control mouthwash after 60 days. The mouthwash based on green tea and hyaluronic acid promoted a reduction in inflammation that was associated with a reduction in the amount of biofilm in patients with total arch prosthesis supported by dental implants.

Key words – Oral biofilm; Chemical control; Dental implants; Inflammation.
