Resumen
Introduction: The radicular grooves are defined as an anomaly of embryological origin, also considered morphological defects present in different teeth at the root level, the presence of these radicular grooves can trigger anatomical complications and generate difficulty or failure for the clinician during endodontic or periodontal treatments.
Objective: To establish the prevalence of root grooves in the first lower premolars and their relationship with the anatomical variations of the duct system from the analysis of tomographic images and with stereomicroscopy.
Materials and methods: A descriptive analytical cross-sectional study was carried out, 126 lower first premolars were selected, obtained from the tooth bank of the Santo Tomás University. CONE BEAM tomographic images (CBCT) were obtained with a resolution of 75 microns with an exposure time of 1 minute, the size of the FOV 8x9 and the Carestream program and the Cs3dimaging program were used, observations were made with a Leica model 2000 Z45L zoom stereomicroscope. The following parameters were recorded: presence and number of radicular grooves, groove location, extent and depth according to the Arizona State University dental anthropology scoring system (ASUDAS), the configuration of the root canal system present according to the Vertucci classification was described to determine the relationship between the sucos and the internal configuration. Data were analyzed using the chi-square test and Fischer's exact using the Stata 15 program.
Results: The frequency of root grooves in the first lower premolars was (40.48%), most of the grooves were located in the middle and apical third of the mesial root surface. Regarding the configuration of the canal system evaluated with the Vertucci classification, a considerable percentage of the teeth (65.87%), 83 teeth, presented type I conduits.
Conclusions: This investigation showed that the configuration of the root canal system is related to the presence of root grooves, complex configurations such as Vertucci type V is related to the presence of root grooves, on the contrary, Vertucci type I configurations presented less presence furrows and its depth was not marked.
