Evolution of dental arches characteristics in two age groups
2005
Introducción: Se comparan las características dimensionales de las arcadas dentarias entre dos grupos de edades diferentes, adolescentes y adultos jóvenes, para analizar las variaciones asociadas a la edad, sexo y a la influencia del tratamiento ortodóncico. Material y método: Se utilizaron dos muestras: 88 pares de modelos de escayola de adolescentes (edad media 14,05 años) y 65 de adultos (edad media 22,15 años). Se usó un método digital para la medición de los diámetros mesiodistales de los dientes, distancias intercaninas e intermolares, longitudes de las arcadas y se obtuvo el apiñamiento dentario inferior. Para el análisis estadístico se agruparon las muestras de cada grupo de edad po…
Association between maxillary and mandibular apical base lengths and severity of dental crowding or spacing in Class II malocclusion subjects: An
2018
Background Anterior crowding/ spacing are one of the major problems that inspire patients to undergo orthodontic treatment. Several factors associated with anterior crowding/ spacing includes arch width and length, mesio-distal tooth diameter and proportions. The aim of the present study was to evaluate the relationship of maxillary and mandibular base lengths to the amount of anterior dental crowding/ spacing in patients with complete class II malocclusions. Material and methods A retrospective study was done with 152 patients who were divided into four groups according to the severity of pre-treatment dental crowding/spacing present in the mandibular arch. Measurements were performed on t…
Analysis of Predisposing Factors for Rapid Dental Calculus Formation.
2020
Background: Calculus accumulation varies widely between individuals. Dental calculus has been associated with the principal periodontal diseases. The aim of this study was to analyze individual characteristics, and salivary and microbiological parameters among patients considered to be rapid calculus formers and patients who form calculus slowly. Methods: Individual characteristics were recorded in a sample of 74 patients (age, sex, smoking, periodontal diagnosis, and dental crowding), as well as salivary parameters (unstimulated saliva flow, pH, and biochemical analysis of saliva) and microbiological parameters (by means of semi-quantitative polymerase chain reaction (PCR) analysis).
