Association of tobacco use and periapical pathosis - a systematic review
ABSTRACT Walter C, Rodriguez FR, Taner B, Hecker H, Weiger R. Association of tobacco use and periapical pathosis - a systematic review. International Endodontic Journal. ABSTRACT: The aim was to review the current evidence regarding an association between tobacco use, that is, cigarette smoking, and periapical pathosis. A systematic MEDLINE search of articles published prior to October 2011 (4th) was conducted using the keywords 'smoking and endodontics OR smoking and periapical index'. The study selection, data preparation and validity assessment were conducted by two reviewers. Nine studies fulfilled the inclusion criteria and represented data from 3008 individuals. The studies differed with respect to (i) study design, (ii) radiographic techniques, (iii) assessment of periapical pathosis, (iv) classification of smoking characteristics and/or (v) potential confounders accounted for in the analyses. Five of six cross-sectional studies revealed a significant positive association (OR 1.35-16.8) between periapical pathosis and current cigarette smoking. One of three longitudinal studies indicated an increased risk (OR 1.7) of root treated teeth for current smokers. The substantial heterogeneity of the included studies limited their interpretation. Further, well-designed studies are required to investigate the association between tobacco use and periapical pathosis.

ABSTRACT: OBJECTIVES: To evaluate the association between cigarette smoking and the frequency of apical periodontitis in female and male patients seeking treatment at the University of Basel (KREBS Project). MATERIALS AND METHODS: This cohort study included full-mouth periapical radiographs of 161 subjects, including 66 current smokers, 26 former smokers and 69 individuals who had never smoked. The periapical region of all teeth was radiographically evaluated using the Periapical Index (PAI) score. Generalised linear mixed-effects models using the logit link were performed. RESULTS: The frequency of apical periodontitis differed based on gender and smoking status. Current male cigarette smokers with <10 or ≥10 pack years showed frequencies of apical periodontitis of 12 % and 5.5 %, respectively, compared to 3.8 % in individuals who had never smoked. The corresponding data for female smokers were 5.7 % and 7.2 % in smokers with <10 or ≥10 pack years, respectively, versus 5.2 % in individuals who had never smoked. The factors "prevalent coronal restoration" (p < 0.001), "prevalent root canal treatment" (p < 0.001) and "quality of root canal filling" (p < 0.001) were significant predictors for apical periodontitis. After adjustment for quality of root canal filling cigarette smoking was not associated with apical periodontitis in current female and male smokers with <10 or ≥10 pack years (p > 0.05). CONCLUSION: Smoking status did not predict apical periodontitis in females and males in this sample group. CLINICAL RELEVANCE: With respect to quality of root canal filling, tobacco use may not be a significant predictor for apical periodontitis.Clinical Oral Investigations 12/2012; 17(8).

ABSTRACT: Background The treatment of periodontal-endodontic lesions is challenging due to the involvement of both periodontal and endodontic tissues.Objective To evaluate the treatment options and outcomes of periodontal-endodontic lesions.Material and methodsA systematic literature search was performed for articles published by 12 May 2013 using electronic databases and hand search. Two reviewers conducted the study selection, data collection and validity assessment. The PRISMA criteria were applied. From 1087 titles identified by the search strategy, five studies and 18 case reports were included.ResultsClinical studies and case reports were published from the years 1981 to 2012. A pronounced heterogeneity exists among studies regarding applied treatment protocols and quality of reporting. In all clinical studies, comprising 111 teeth, a non-surgical root canal treatment (RCT) was performed as initial treatment step. Non-surgical and/or a surgical periodontal therapy was applied in some studies without reevaluation of the endodontic healing. Probing pocket depth reductions were reported in all included studies, comprising the data from 74 teeth at follow-up.ConclusionsA sequential treatment with root canal treatment as a first treatment step appears to be reasonable. An adequate time for tissue healing is suggested prior to reevaluation.This article is protected by copyright. All rights reserved.Journal Of Clinical Periodontology 04/2014; 41(8).
