Efficacy of Adjunctive Chlorhexidine in non-surgical treatment of Peri-Implantitis/Peri-Implant Mucositis: An updated systematic review and meta-analysis

Abstract

Objective: The current review aimed to assess the efficacy of adjunctive chlorhexidine (CHX) in the non-surgical treatment of peri-implantitis/peri-implant mucositis.
 Methods: PubMed, Embase, Science Direct, CENTRAL, and Google Scholar databases were searched up to 10th March 2022 for relevant randomized controlled trials or controlled clinical trials.
 Results: Fourteen studies were included. Meta-analysis revealed significantly lower probing depths in peri-implant mucositis patients using CHX adjuncts as compared to controls (SMD: -1.49 95% CI: -2.56, -0.42 I2=95% p=0.006). However, the same effect was not noted in peri-implantitis (SMD: -1.18 95% CI: -0.04, 2.40 I2=96% p=0.06). CHX was not found to improve bleeding of probing in peri-implant mucositis while sufficient data was unavailable for peri-implantitis. Results on other outcome variables were conflicting.
 Conclusion: Evidence on the efficacy of adjunctive CHX for peri-implant mucositis is conflicting. Similarly, strong conclusions on the effect of CHX for peri-implantitis cannot be drawn due to limited number of studies. Overall, there seems to be a trend of non-significant impact of CHX on outcomes of peri-implant mucositis as well as peri-implantitis.

Titanium surfaces with biomimetic topography and copper incorporation to modulate behaviors of stem cells and oral bacteria

“…In the oral environment, more than 500 microbial strains play different roles in the oral biofilm formation and peri-implantitis ( Brunetti et al, 2023 ; Ye et al, 2023 ). Many studies have demonstrated that there is a higher risk of pathogens colonization on the susceptible implant surface during the initial 6 h after surgery ( Jin et al, 2019 ; Agarwalla et al, 2022 ), thus making the antimicrobial effects on the first day vital to clinical success.…”

Decision-making on peri-implant mucositis management and treatment approaches

“…Moreover, mechanical debridement supplemented with chlorhexidine (CHX) application resulted in similar improvement as compared to mechanical debridement only. 14,44,45,46 In addition to these methods, various adjunctive treatments have been considered, including antimicrobial photodynamic therapy, antiseptic injections, systemic and local antibiotics, probiotics, and antiseptic mouthwashes 47 (Fig. 1).…”

Eficácia do chip de gluconato de clorexidina na terapia da peri-implantite

“…Por isso, o uso de antimicrobianos locais inseridos diretamente na bolsa, são uma alternativa para elevar a concentração do fármaco utilizado (JOHN et al, 2015;YE et al, 2023). O chip de CHX é um chip reabsorvível com 2,5 mg de CHX incorporado em uma matriz de gelatina hidrolisada reticulada.…”
