Aims: Periodontitis is one of the most widespread diseases worldwide. Many efforts have been made to increase the efficacy of periodontitis therapy as much as possible. Recently, minimally invasive nonsurgical techniques (MINST) were introduced in the periodontal field as an alternative to minimally invasive surgical techniques (MIST). This clinical audit aims to evaluate the results of MINST in the initial phase of treatment for periodontitis. Materials and methods: One hundred seven patients with periodontitis who were treated with MINST between 2013 and 2017 and reevaluated after 2 months were included in this clinical audit. The primary outcome analyzed was the proportion of pocket closure. The secondary outcomes were tooth extraction before active periodontal therapy, full-mouth plaque score (FMPS) change, full-mouth bleeding score (FMBS) change, average probing pocket depth (PPD) reduction, and average clinical attachment level (CAL) gain between the baseline and reevaluation values. Results: A total of 2,407 teeth were included in the analysis. At the patient level, the treatment resulted in a mean pocket closure rate of 71.6 ± 15.7% for sites with an initial PPD ≥5 mm. The treatment was statistically significantly (p < 0.001) more effective with respect to the primary outcome compared with expected values reported in a recent meta-analysis (57%). The subgroup analysis revealed statistically significant differences between single and multirooted teeth and between shallow (5–6 mm) and deep pockets (≥7 mm) at the baseline. Conclusion: Nonsurgical periodontal therapy with MINST achieved satisfactory results that were better than expected based on the scientific literature. Single-rooted and shallow pockets showed the best proportion of pocket closure at the reevaluation after treatment. Clinical significance: Minimally invasive nonsurgical techniques can be the treatment of choice when approaching periodontally diseased patients with nonsurgical periodontal therapy.
