The Relationship between Root Concavities in Premolars and Mandibular Molars and Chronic Periodontitis: A Tomographic Study
Journal Title: International Journal of Contemporary Medical Research - Year 2017, Vol 4, Issue 8
Abstract
Introduction: Root concavities accumulate plaque by hindering effective cleansing predisposing to periodontitis. CBCT scans provide high-resolution images that display root concavities and alveolar bone defects. The aim of this study was to correlate the impact of root concavities in premolars and mandibular molars with chronic periodontitis. Material and methods: Three dimensional reconstruction in CBCT was used to observe root concavities and alveolar bone defects in mesial and distal sites of 235 premolars and mandibular molars from 20 patients. Results: The incidence of root concavity was 100% and 70% in mesial and distal sites of maxillary first premolars. In mandibular molars the incidence was 95-100%. The agewise distribution of concavities was not statistically significant. Males showed more concavities and more bone loss as compared to females. Probing depth and clinical attachment loss of teeth with root concavities were significantly higher than those without(p < 0.05). Ramp bone defects were dominant for teeth without concavities, while craters were seen for teeth with concavities (p < 0.05). Conclusion: Root concavities of the premolars and mandibular molars were associated with periodontal disease and interproximal alveolar bone defects.
