Dental anomalies in a Portuguese population
2013
The aim of this study was to evaluate the prevalence and pattern of agenesis, supernumerary teeth, impacted teeth and transpositions, as well as the relation between them, in a Portuguese sample.The study sample consisted of 2888 patients, observed between 2005 and 2009 at the Dentistry Clinic of the Instituto Superior de Ciências da Saúde-Norte (ISCSN, Portugal). The study included evaluation of the following parameters: agenesis of all teeth, supernumerary teeth, impacted permanent teeth and tooth transposition. The age range varied from 7 to 21 years. In order to study the absence of the third molar, subjects aged below 14 years were excluded. Statistical analysis was performed using SPS…
Nonsyndromic cleft lip and palate, gastric cancer and tooth agenesis
2018
Background To determine the frequency of nonsyndromic cleft lip and/or palate (NSCL/P) in first-degree relatives and to analyze the prevalence of tooth agenesis in patients with gastric cancer. Material and Methods This cross-sectional, observational, case-control study included 798 patients attended at hospital Santa Casa in Montes Claros, Minas Gerais and Alfa Institute of Gastroenterology of the Federal University of the Minas Gerais. Information on basic demographic data and tooth agenesis of both groups and their family history of NSCL/P in first-degree relatives were evaluated. The collected information was stored in a database and analyzed using statistical program SPSS® version 21.0…
Dental anomalies inside the cleft region in individuals with nonsyndromic cleft lip with or without cleft palate
2015
Background Individuals with non syndromic cleft lip with or without cleft palate (NSCL±P) present high frequency of dental anomalies, which may represent complicating factors for dental treatment. The aim of this study was to investigate the prevalence of dental anomalies inside cleft area in a group of Brazilians with NSCL±P. Material and Methods Retrospective analysis of 178 panoramic radiographs of patients aged from 12 to 45 years old and without history of tooth extraction or orthodontic treatment was performed. Association between cleft type and the prevalence of dental anomalies was assessed by chi-square test with a significance level set at p≤ 0.05. Results Dental anomalies were fo…
Frequency and characteristics of tooth agenesis among an orthodontic patient population
2009
Purpose: The objectives of this study were to investigate the prevalence and characteristics of tooth agenesis and the associated skeletal morphology and arch widths in a group of Turkish patients seeking orthodontic treatment. Material and Methods: We designed a retrospective study composed of pre- and post-treatment panoramic radiographs and lateral cephalometric films of 3,341 patients (2,040 females and 1,301 males). Tooth agenesis was evaluated for hypodontia and oligodontia -excluding the third molars- from the orthopantomograms. The significance test for the differences in the skeletal morphology between hypodontia and non-hypodontia patients was performed using the Pearson chi-squar…
