Objective: To compare the soft tissue thickness of the chin in individuals with different patterns of facial growth on lateral cephalic radiographs of the digital skull in individuals between 18 and 45 years of age. Material and Methods: a correlational study was carried out evaluating 160 lateral radiographs using a 13.3-inch screen using AutoCAD 2020 software obtained from a radiological center in the city of Cuenca, in the period 2019. It was divided into four groups according to the pattern of facial growth (SN / G-Gn): Low, Medium Low, Medium High and High and the thickness of the soft tissues of the chin was measured sagittally at the Pogonion, Gnation and Menton level of the bone structures at their respective points in soft tissues. The Spearman Rho correlation was used to evaluate the means of the thickness of the soft tissues of the chin and facial pattern, for the comparison b...

Objective: To assess the presence of microorganisms on the surfaces of sterile instruments in the periodontics area of a university pre-professional practice clinic. Materials and methods: A descriptive and observational study, in which 100 randomly selected samples of periodontics instruments were selected. The samples collected were analyzed using cultures on specific media, including blood agar, Sabouraud agar, and eosin methylene blue agar, which enabled the primary identification of four classes of microorganisms: Gram-positive cocci, Gram-positive bacilli, Gram-negative bacilli, and yeasts. Results: Of the instruments analyzed, 19% (n = 19) were contaminated. The highest contamination rate was observed in Gracey 3/4 periodontal curettes, with 30% (n = 12), in which only gram-positive cocci were identified, with no positive results for gram-positive bacilli, gram-negative bacilli, o...
