Abstract

Background: Extraction of periodontally compromised or strategically non-important teeth is often an integral part of non-surgical periodontal treatment (NSPT). This study evaluated the association between the status of adjacent teeth and the outcome of NSPT on molars. Methods: Charting data of patients with generalized chronic periodontitis receiving NSPT in 2012–2014 were included. The association between initial clinical parameters and significant clinical improvement, including the reductions of probing pocket depth (PPD) and clinical attachment loss (CAL), in molar teeth with severe periodontitis after NSPT was assessed by a generalized linear model and logistic regression. Results: ≥7 mm PPD and <2 mm gingival recession (REC) at the tooth level, and ≥7 mm PPD, ≥7 mm CAL and <2 mm REC at the site level, were associated with significant clinical improvement. Absence or extraction of an adjacent tooth achieved an additional 0.22–0.23 mm and 0.60–0.83 mm clinical improvement. Among the interproximal sites, ≥7 mm PPD, <2 mm REC, ≥7 mm CAL, <Degree II furcation involvement, and absence of an adjacent tooth were associated with significant clinical improvement. Conclusion: Absence or extraction of teeth during NSPT significantly improves the PPD and CAL of the adjacent periodontal sites of molars.

Highlights

Periodontitis is a chronic infectious disease of the periodontium that affects over 50% of the adult population in Taiwan [1]
The exclusion criteria were: (1) had fewer than 16 teeth at re-evaluation of non-surgical periodontal treatment (NSPT); (2) the initial periodontal status did not fulfill the definition of generalized chronic periodontitis according to the classification defined by the American Academy of Periodontology in 1999 and updated in 2015 [13]; (3) was recorded as a smoker during NSPT; (4) no record of systemic diseases affecting periodontal health or wound healing; (5) had a record of taking antibiotics, anti-inflammatory drugs, or drugs affecting wound healing during the course of NSPT
The data from this study revealed that the absence or extraction of a tooth adjacent to periodontitis-affected molars during NSPT contributed to improved treatment outcomes (Tables 3 and 4) and supported the argument that the absence of adjacent teeth could provide additional benefits to NSPT on molars

Summary

Introduction

Periodontitis is a chronic infectious disease of the periodontium that affects over 50% of the adult population in Taiwan [1]. Several guidelines have been established, based on large-scale evaluation of the interaction between clinical periodontal parameters and disease progression, to predict the prognosis of periodontitis-affected teeth and subsequent treatment planning [2,4,5,6,7]. Extraction of periodontally compromised or strategically non-important teeth is often an integral part of non-surgical periodontal treatment (NSPT). The association between initial clinical parameters and significant clinical improvement, including the reductions of probing pocket depth (PPD) and clinical attachment loss (CAL), in molar teeth with severe periodontitis after NSPT was assessed by a generalized linear model and logistic regression. ≥7 mm PPD, ≥7 mm CAL and
