Mapeo del piso de cámara pulpar de primeros molares superiores permanentes mediante tomografía axial computarizada

The relationship between the shape of the pulp floor determines the number of root canals found in a dental piece. The first investigations date back to 1978 by Sergio Acosta et al, as well as in 2004 by Krasner and Rankow; At present, this type of study helps to detect the canals found in the dental organ, even more so in the upper first molar, whose internal root anatomy is complex, especially to determine the presence of a second mesiopalatine canal (MB2). Aim: To determine by computerized axial tomography (CBCT) the main characteristics of the floor of the pulp chamber of the upper first molars. Materials and Methods: Descriptive and cross-sectional observational approach study in which 123 CBCTs were observed, the CBCT cohort was from the first to the last day of May 2023, to obtain a probabilistic sample of 107 CBCTs, in cut. axial at the cementoenamel limit. Results: Of the 187 upper molars examined, the most frequently found shape was the "Y" shape in 164 molars, of which between 3 and 4 canals were visualized, followed by the "four" shape observed in eleven teeth, as well as well as the "triangular" shape in six dental pieces, the "7" shape in four dental pieces and only the T and rectangular shapes were observed in 1 dental piece. Conclusions: The different anatomical features of the "rostrum canalium" in the upper first molars were determined by CBCT, the predominant pulp floor shape was the "Y" shape in dental organ 16.
