Adyani‐Fard D, Kim T‐S, Eickholz P. Interproximal bone loss at contra‐lateral teeth with and without root canal filling in periodontitis patients. J Clin Periodontol 2011; 38: 269–275. 38: 269–275. doi: 10.1111/j.1600‐051X.2010.01657.x. Abstract Aim: The purpose of this study was to test the hypothesis that teeth that are adequately endodontically treated develop more periodontal bone loss than their contra‐lateral counterpart without root canal filling (RCF) in relation to the restoration margin (RM) in periodontitis patients. Methods: In 53 periodontitis patients (26 females; 34–73 years of age), 66 pairs of radiographs were sampled. Each pair of radiographs depicted one pair of contra‐lateral teeth: one with and one without RCF. All radiographs were digitized. Using a PC program the linear distances cemento‐enamel junction (CEJ) or RM to the alveolar crest (AC) and CEJ/RM to bony defect (BD) were measured at the site of most pronounced bone loss. Comparisons were made according to RCF, RM, site (mesial/distal), jaw and tooth type (anterior/posterior). Results: The study showed statistically significant differences for the distance CEJ/RM–BD only for tooth type (anterior: 6.17±3.01 mm, posterior: 5.03±2.59 mm, p =0.044; without RCF: 5.14±2.82 mm, RCF: 5.57±2.70 mm, p =0.159; without RM: 5.67±2.98 mm, RM: 5.16±2.61 mm; p =0.322; mesial: 5.62±2.98 mm, distal: 5.06±2.24 mm; p =0.238; maxilla: 5.55±3.04 mm, mandible: 5.20±2.52 mm; p =0.486). Conclusions: Teeth with endodontic treatment failed to exhibit more bone loss than endodontically untreated teeth.
