Adjunctive glycine powder air-polishing for the treatment of peri-implant mucositis: an observational clinical trial.

OBJECTIVES: The aim of this study was to make a comparative evaluation of professional oral hygiene with or without the adjunct of glycine air-powder system for the treatment of peri-implant mucositis. METHODS: After the application of inclusion and exclusion criteria, patients were divided in two groups: in control group, patients were treated with professional oral hygiene manoeuvres (POH) while in the test group, glycine air-powder system (SGA) was adjuncted to professional oral hygiene. Probing depth (PD), bleeding index (BI) and plaque index (PI) were measured at baseline, and 3 and 6 months after the treatment. RESULTS: A total of 30 patients (15 per group) were selected for the study. In POH e SGA group, PD was, 2.86 ± 0.37 and 3.00 ± 0.36 mm at baseline, 2.90 ± 0.53 and 2.62 ± 0.50 mm after 3 months, 2.96 ± 0.56 and 2.41 ± 0.54 mm after 6 months, respectively, significantly lower in SGA group in the last follow-up visit. In both groups, both PI and BI decreased over time. CONCLUSIONS: The present reports showed that both techniques were useful for the treatment of peri-implant mucositis. In the test group (with glycine powder), a significant reduction of probing depth was observed.

Topical application of 1% chlorhexidine gel versus 0.2% mouthwash in the treatment of peri-implant mucositis. An observational study.

OBJECTIVE: The aim of this study was to compare the use of two chlorhexidine-based antimicrobial agents as an adjunct to mechanical therapy for the treatment of peri-implant mucositis. MATERIALS AND METHODS: Thirty patients with peri-implant mucositis were included in the study and randomized in two groups. In addition to mechanical therapy, group A was treated with chlorhexidine 0.2% mouthwash, while group B was treated with chlorhexidine 1% gel. Probing depth, plaque index and bleeding index were recorded at each scheduled follow-up visit: ten days, 1 month and 3 months after giving the patients the assigned formulation. Patients had to fill in a questionnaire investigating their satisfaction and ease of use of the product. RESULTS: A total of 23 patients (13 in group A and 10 in group B) attended all the follow-up visits. Chlorhexidine 0.2% mouthwash and chlorhexidine 1% gel were equally useful in the treatment of peri-implant mucositis leading to the reduction in inflammatory parameters. Probing depth decreased over time in both groups. Patients showed preference for gel formulation even if they found it more difficult to use. CONCLUSIONS: Adjunctive treatment with different chlorhexidine formulations was beneficial to the treatment of peri-implant mucositis. Besides, no differences could be found between 0.2% mouthwash and 1% gel.

Evaluation of chlorhexidine 0.05% with the adjunct of fluoride 0.05% in the inhibition of plaque formation: a double blind, crossover, plaque regrowth study.

OBJECTIVE: The aim of this study was to evaluate the effect of mouthrinses containing 0.05% chlorhexidine + 0.05% fluoride solution on early dental plaque regrowth. MATERIALS AND METHODS: Thirty periodontally healthy subjects were included in the study. A crossover 4-day plaque regrowth protocol was adopted. The test product was initially used in 15 patients, while a placebo was administered to the other 15 patients. Then, after a washout period, each patient used the other product. No other oral hygiene manoeuvre was allowed. Full-mouth plaque and bleeding scores (FMPS and FMBS) were evaluated at baseline and after 4 days. RESULTS: All subjects completed the study. The mean age was 27 ± 8.4 years. Five patients were smokers with a mean daily consumption of 1 ± 2.5 cigarettes. FMPS at baseline was 8.0 ± 4.4 for control group and 7.9 ± 3.8 for test group, without significant difference. After the 4-day plaque regrowth the mean FMPS significantly increased to 31.9 ± 16.5 and 36.3 ± 16.1 for control and test group, respectively (no significant difference between the two groups). CONCLUSIONS: The test product was safe and well tolerated by subjects. The similar outcomes of the two experimental groups suggest that the two products have an equivalent effect on early dental plaque regrowth. Studies with longer follow-up are needed to clarify whether there is a beneficial long-term effect of daily rinses with the tested solution.

Clinical evaluation of an implant maintenance protocol for the prevention of peri-implant diseases in patients treated with immediately loaded full-arch rehabilitations.

OBJECTIVE: The aim of this prospective study was to assess the outcomes of an implant maintenance protocol for implants supporting a full-arch rehabilitation. MATERIALS AND METHODS: Sixty-one patients (28 women and 33 men) treated with immediately loaded full-arch rehabilitation, both mandibular and maxillary, supported by a combination of two tilted and two axial implants, were included in the study. Patients were scheduled for follow-up visits every 6 months for +2 years, then yearly up to 4 years. Each patient received professional oral hygiene treatment and detailed oral hygiene instructions. During each visit, modified plaque index, bleeding index and probing depth were assessed. The presence of peri-implant tissue inflammation was also evaluated. RESULTS: Mean observation time, considering both mandible and maxilla, was 18.3 months ranging from 6 months to 5 years. Both plaque and bleeding indexes frequency decreased over time. Probing depth was stable (2.46 ± 0.5 mm at 4 years). Only three implants were lost due to peri-implantitis (1.4% at 12 months), whereas the incidence of peri-implant mucositis was less than 10% in each considered period. CONCLUSIONS: The adoption of a systematic hygienic protocol is effective in keeping low the incidence of peri-implant mucositis as well as in controlling plaque accumulation and clinical attachment loss.
