“…Here, we propose the use of photoacoustically induced streaming and secondary cavitation to achieve improved cleaning efficacy in the apical region of the periodontal and peri-implant pockets. Laser-induced cavitation has already been applied to remove biofilm in infinite volumes and in endodontics [21] , but has not been used for biofilm removal in the constrained narrow geometries characteristic of periodontal or peri-implant pockets. In this study, we used a prefabricated narrow wedge system with one of the boundaries made of polydimethylsiloxane (PDMS) to mimic a periodontal or peri-implant pocket.…”

“…Due to the high absorption coefficient of Er:YAG in aqueous medium, laser light is efficiently absorbed in a very small volume of irrigant, resulting in photoacoustic cavitation, which activates the flow of the irrigant and brings it to the distal parts of the irrigation system [ 15 , 16 , 17 , 18 , 19 , 20 , 21 ]. We showed recently that non-contact photoacoustic fluid streaming and cavitation with Er:YAG-SSP laser modality can effectively remove biofilms from infinite volume geometries [ 22 , 23 ]. Although the results from a large infinite volume geometry are encouraging [ 15 , 16 , 24 , 25 , 26 , 27 ], it is less well known how biofilms can be removed from confined and difficult to access volumes.…”

The disinfection and removal of biofilm from titanium dental implants remains a great challenge in oral medicine. Here we present results of novel photoacoustic irrigation laser modalities for biofilm removal in model geometries mimicking the peri-implant pocket. The efficacy of single pulse (Er:YAG-SSP) and dual pulse (Er:YAG-AutoSWEEPS) photoacoustic irrigation modalities were determined for Enterococcus faecalis biofilm decontamination from titanium surfaces in narrow cylindrical and square gap geometries. The density of bacteria as well as the number of live bacteria were determined prior and after different photoacoustic treatments. Both SSP and AutoSWEEPS photoacoustic irrigation techniques removed at least 92% of biofilm bacteria during the 10 s photoacoustic treatment. The effectiveness of cleaning was better in the narrow square gap geometry compared to the cylindrical geometry. The dual pulse Er:YAG-AutoSWEEPS photoacoustic irrigation showed better results compared to SSP modality. No chemical adjuvants were needed to boost the effectiveness of the photoacoustic irrigation in the saline solution. The results imply that photoacoustic irrigation is an efficient cleaning method for debridement and decontamination in narrow geometries and should be considered as a new therapeutic option for the treatment of peri-implant diseases.

ObjectiveTo assess which decontamination method(s) used for the debridement of titanium surfaces (disks and dental implants) contaminated with bacterial, most efficiently eliminate bacterial biofilms.Material and MethodsA systematic search was conducted in four electronic databases between January 1, 2010 and October 31, 2022. The search strategy followed the PICOS format and included only in vitro studies completed on either dental implant or titanium disk samples. The assessed outcome variable consisted of the most effective method(s)—chemical or mechanical— removing bacterial biofilm from titanium surfaces. A meta‐analysis was conducted, and data was summarized through single‐ and multi‐level random effects model (p < .05).ResultsThe initial search resulted in 5260 articles after the removal of duplicates. After assessment by title, abstract, and full‐text review, a total of 13 articles met the inclusion criteria for this review. Different decontamination methods were assessed, including both mechanical and chemical, with the most common method across studies being chlorhexidine (CHX). Significant heterogeneity was noted across the included studies. The meta‐analyses only identified a significant difference in biofilm reduction when CHX treatment was compared against PBS. The remaining comparisons did not identify significant differences between the various decontamination methods.ConclusionsThe present results do not demonstrate that one method of decontamination is superior in eliminating bacterial biofilm from titanium disk and implant surfaces.
