| Abstract: | ObjectiveThe aim of this 1-year follow-up randomized control trial was to compare the clinicoradiographic status of implants that were disinfected with antimicrobial photodynamic therapy (aPDT) and 0.2% chlorhexidine gel immediately before prosthesis delivery.MethodsForty-five partially edentulous patients with implants placed in the region of missing mandibular first molars and a history of periodontal diseases were included. Immediately before prosthesis delivery, patients were divided into three groups. In groups 1 and 2, implant abutment disinfection (IAD) was performed using aPDT and 0.2% chlorhexidine immediately before prosthesis delivery. In Group-3, IAD was performed using a steaming protocol. Peri-implant modified plaque index (mPI), modified gingival index (mGI), probing depth (PD) and crestal bone loss (CBL) were assessed at 1 year of follow-up. Power analysis was done and group comparisons were done. Logistic regression analysis was done to corelate clinical parameters with demographic variables. P<0.01 was considered statistically significant.ResultsIn total, 15, 15, and 15 implants were present among patients in groups 1, 2 and 3, respectively. There was no statistically significant difference in peri-implant mPI, mBoP, PD and CBL in all groups (Table 2). None of the patients had periodontal disease and there was no statistically significant correlation between peri-implant clinicoradiographic parameters with age, toothbrushing and flossing habits, and duration of implants in function. Eighty percent, 86.7% and 100% individuals in groups 1, 2 and 3, respectively reported that they were brushing teeth twice daily. Flossing of interproximal spaces once daily was reported by 66.7%, 73.3% and 66.7% individuals in groups 1, 2 and 3, respectively.ConclusionAs long as oral hygiene is stringently maintained after implant prosthesis delivery, IAD can be performed using aPDT, 0.2% CHX gel or steam-disinfection. |
