Objectives: To identify the anatomical characteristics of human permanent natural dental pieces from the incisor group. Materials and Methods: The study was observational, descriptive, and cross-sectional. 96 incisors collected between 2015 and 2020 were analyzed, belonging to the Morphoteca of Introduction to Dentistry at the Faculty of Dentistry of the National University of the Northeast - Corrientes, Argentina. The teeth were grouped by location in the arch and observed using a metal base magnifying glass with a flexible arm, a 90 mm 3x glass lens. Digital photographic registration and anatomical description of the Upper Central Incisor (UCI), Upper Lateral Incisor (ULI), Lower Lateral Incisor (LLI), and Lower Central Incisor (LCI) were performed. The crown shape was determined through Crespi’s classification: quadrangular, trapezoidal with a larger base at the cervical, trapezoida...

Objective. To verify the thickness of dental hard tissues at present. Methods. Observational, descriptive and cross-sectional study. Ninety four human permanent teeth existing in the library of the Faculty of Dentistry of the National Northeast University were collected during 2004-2014, these were free of injuries and restorations, with full crowns and root were used. Eight samples from each group (incisors, canines, premolars, and molars) were selected to measure the thickness of hard tissues of incisal, occlusal, central, cervical, and apical thirds. A Model AA flat vice and carborundum discs were used in a Dremel 4000 micromotor to make longitudinal cuts in the mesiodistal direction of each selected piece and the surface was polished with a pumice stone until minimum thickness was obtained. The measurement was made in millimeters with a digital microscope, resolution up to 2M pixel, ...
