Clinical and patient-centered outcomes post non-surgical periodontal therapy with the use of a non-injectable anesthetic product: A randomized clinical study.

Aim: The aim of this study was to determine the impact of different full-mouth decontamination (FMD) protocols on the effectiveness of an intrapocket anesthetic gel in periodontal maintenance patients.
Methods: Patients undergoing the periodontal maintenance program and with the need for FMD participated in this study. Patients were randomly allocated to non-surgical periodontal therapy (NSPT) with either a preparatory 15-day decontamination phase, including chlorhexidine mouth rinse and domiciliary hygiene instructions (modified FMD: test group), or without it (FMD: control group). In both groups, NSPT was performed with the aid of a non-injectable anesthetic gel. Clinical and patient-related outcomes were recorded during a 6-month follow-up period.
Results: Sixty patients completed the 6-month study. Both groups experienced relevant clinical improvements after NSPT, but the test group showed a significant change in periodontal parameters already after the initial 15-day preparatory period, and overall significantly better results in periodontal outcomes when compared with the control group at the last 6-month follow up: the gingival index was 2.07 ± 1.25 in the control group and 1.13 ± 0.51 in the test group. Less pain and dental-related anxiety were perceived by patients in the test group showing a 6-month mean visual analog scale of 2.13 ± 1.25 in the control group and 1.13 ± 0.83 in the test group.
Conclusion: The present study suggested that the modification of the standard FMD could improve the clinical efficacy of non-injectable anesthetic, along with patients' short- and mid-term appreciation and compliance.
