“…Among these factors, physiological variation and anomalies of morphology/anatomy of teeth have been described as local conditions that promote the onset of periodontal diseases. The first ones include the variations in the anatomical characteristics of radicular surfaces, such as the length, the width, the degree of root taper, the presence of root concavity, the root proximity, whereas the second ones, include marginal ridge discrepancies, cervical enamel projections, pits and grooves on tooth surfaces [ 5 , 6 , 7 , 8 , 9 ].…”

Background: The aim of this cross-sectional study was to (i) determine the prevalence and distribution of developmental grooves in a young population and (ii) to evaluate the local periodontal conditions. Methods: Two hundred and fifty-one students with a mean age of 22.9 ± 4.7, attending the School of Dentistry and Dental Hygiene of Vita-Salute San Raffaele University (Milan, Italy) were included. The subjects underwent a clinical evaluation by two calibrated examiners. The following clinical parameters were recorded for each site presenting a radicular groove and for each corresponding site on an adjacent tooth used as control: probing pocket depth, plaque index, bleeding on probing, recession depth. Results: The prevalence of radicular grooves at patient and tooth level was 15.9% and 5%, respectively. When compared to control sites, the number of teeth with a radicular groove that presented plaque and bleeding on probing was higher. The logistic regression analysis showed that the presence of radicular grooves was significantly associated with the presence of plaque (OR, 6.14, p < 0.001) and of bleeding on probing (OR, 2.91, p = 0.01). Conclusions: The presence of radicular grooves increases the possibility of developing gingival inflammation by acting as a plaque retentive factor.
