- Abstract: Introduction: Root grooves are considered a risk factor for periodontal disease. The purpose of this study was to measure the length of the root of lower central incisors (LCI). as well as the width and depth of the concavities oftheir proximal surfaces. Material and methods: The width and depth of root concavities, as well as root length, were evaluated in 90 LCI. AlI teeth were measured using a digital contour measuring instrument (Contracer@) for the root grooves and a digital calliper for evaluating root length. Results: After statistical analysis (tStudent and Kruskal-Wallis Anova tests, p<0.05) it was possible to confirm: the mean root length on its distal surface (13.88 :t 1.47 mm) and on its mesial surface (13.76:t 1.50 mm). Concavities were present in 100% of the samples; concavities were found 2 mm, coronalIy from the CEJ, at the CEJ, and at alI root surface. The concavities were wider than deeper; on the mesial surface, the greatest width was 1.877 mm and the greatest depth was 0.135 mm; on the distal surface the greatest width was 1.717 mm and the greatest depth was 0.118 mm. Conclusion: The distal surface ofthe lower central incisor is the longest. The root concavities on the proximal surfaces are present in 100%; the greatest width and depth was at 6 mm apicalIy from the CEJ at both sides, which corresponds to the root middle, third. One must get acquainted to the morphological variations of roots to enhance diagnosis, prognosis and treatment
