Treatment of peri-implant mucositis: Adjunctive effect of glycine powder air polishing to professional mechanical biofilm removal. 12 months randomized clinical study.

INTRODUCTION: To evaluate the adjunctive effect of glycine-powder air-polishing (GPAP) to full-mouth ultrasonic debridement (Fm-UD) in the treatment of peri-implant mucositis, and to determine the impact of implant and patient-level variables for disease resolution. METHODS: Individuals with a diagnosis of peri-implant mucositis were consecutively included in this randomized parallel arm clinical study. All the participants received a session of Fm-UD. Only implants allocated to the test group were additionally treated with GPAP. Clinical assessments were recorded at baseline, at 3 and at 12 months following intervention. The primary outcomes were complete disease resolution (DR1), defined as absence of bleeding sites at probing per implants, and partial disease resolution (DR2), measured as the presence of less than two bleeding sites at probing per implant. A final logistic multivariate regression model was built to evaluate the predictive role of implant and patient-level variables on DR. RESULTS: Fifty two patients and 157 implants were included. Both groups displayed significant reduction in the extent of bleeding on probing and plaque levels. At 12 months, DR1 was achieved in 16% and 27% of participants for the test and the control group respectively. IDR1 was best predicted by the number of bleeding sites (OR = 2.7, p = 0.04) and the greatest PPD value (OR = 2.7, p = 0.05), while IDR2 by the prosthetic connection (OR = 2.59, p = 0.02), the mean PPD (OR = 2.23, p = 0.04), the FMBS (OR = 4.09, p = 0.04), and number of implants (OR = 4.59, p = 0.02). CONCLUSIONS: Despite significant improvements of clinical signs of peri-implant inflammation, the use of GPAP appears to have no adjunctive effect as compared with Fm-UD alone in the achievement of DR. Elevated initial levels of bleeding and PD predicted inferior likelihood of reaching disease resolution. The present randomized parallel arm clinical study was registered on Clinicaltrials.gov and received the following registration number: NCT05801315. This clinical trial was not registered prior to participant recruitment and randomization (https://register.

COVID-19 and dental workers: The Italian Society of Periodontology and Implantology (SIdP) survey.

OBJECTIVES: To evaluate the proportion of COVID-19 infections among a population of Italian Dental workers across different geographical area of Italy and to analyze the impact of both the preventive measures/strategies adopted and the psychological influences. SUBJECTS AND METHODS: The current cross-sectional survey was administered with a web-based form. To be eligible for the study, participants had to be 18 years and being dentists or dental hygienists members of the Italian Society of Periodontology and Implantology (SIdP). A 23-item questionnaire concerning positiveness to COVID-19, clinical strategies and psychological attitude within the pandemic was administered. Sub-group analysis was conducted according to geographical macro-area. RESULTS: A total of 790 dentists and dental hygienists were included. A total of 4.7% participants developed a positive diagnosis to COVID-19. The Northwest of Italy experienced almost double of COVID-19-positive participants (p < 0.05). Preoperatory mouthwashes together with natural air change/ventilation were the most frequent approaches used to prevent COVID-19 outbreak. Positive and proactive attitudes were predominant among participants. Only a reduced proportion feels some concerns for the future. CONCLUSIONS: Prevalence of positive COVID-19 among dental workers in Italy was double in Northwest area in comparison with the whole country proportion. Preventive strategies comprise mainly ultrasound reduction and preoperative mouthwashes.
