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, ...

This research sought to define a facial anthropometric pattern that characterizes individuals from the City of Corrientes. Objectives: Obtain the facial morphometry of individuals of both sexes and determine its prevalence. To determine the most frequent types of maxillary arches in the sample. To analyze the facial variation through the morphometric index in relation to the shape of the maxillary arch. Materials and methods: This study was observational, descriptive, and crosssectional. The facial morphometric modification was analyzed in relation to the shape of the upper dental arch, which was presented by a group of 50 patients of both sexes, born in the city of Corrientes, Argentina with an age range between 18 to 40 years, who voluntarily attended for his attention to the FOUNNE University Dental Hospital and the Rossi Candia SAPS dependent on the Municipality of the City of Corrie...

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...

Objectives: Identify the histological characteristics of bovine dentin using histological technique by decalcification with Masson's Trichrome staining. Materials and Methods: This was an observational and descriptive study using units of analysis. Bovine teeth were used, which were subjected to a decalcification technique and Masson's trichrome staining. Microscopic observation and registration of the structures was carried out. Results: In the microscopic observation of the teeth subjected to decalcification, dentin, predentin and the structural organization of the tubular and peritubular dentin were observed. The odontoblasts arranged in a palisade with the odontoblastic process included within the dentinal tubule and the periprocedural space. The presence of interglobular dentin is not observed in areas of coronary dentin. The histomorphological pattern corresponding to dentin-preden...
