A comparison of the dental status and treatment needs of older adults with and without chronic mental illness in Sevilla, Spain
2012
Objectives: To study the dental status and treatment needs of institutionalized older adults with chronic mental illness compared to a non-psychiatric control sample. Study Design: The sample size was 100, in which 50 were psychogeriatric patients (study group; SG) classified according to DSM-IV, with a mean age of 69.6 ± 6.7 years, and 50 non-psychiatric patients (control group; CG), with a mean age of 68.3 ± 6.9 years. Clinical oral health examinations were conducted and caries were recorded clinically using the Decayed, Missing and Filled Teeth Index (DMFT). Results were analyzed statistically using the Student’s t-test or analysis of variance. Results: Caries prevalence was 58% and 62% …
Prevalence of enamel defects in primary and permanent teeth in a group of schoolchildren from Granada (Spain)
2012
Objective: The purpose of this study was to determine and compare the prevalence and presentations of developmental defects of the enamel (DDE) in the primary and permanent dentitions of a group of healthy schoolchildren residing in Granada (Spain). Study Design: A total of 1,414 healthy schoolchildren were examined using modified DDE criteria for recording enamel defects. Results: The prevalence of DDE of any type was 40.2% in primary dentition and 52% in permanent dentition (p<0.033). Of the 31,820 primary and permanent teeth examined in the study, 699 (4.1%) primary and 1,232 (8.3%) permanent teeth had some form of DDE. Diffuse opacity was the most common type of DDE observed in primary …
Accuracy of the estimation of dental age in comparison with chronological age in a Spanish sample of 2641 living subjects using the Demirjian and Nol…
2016
Age estimation is an important procedure in forensic medicine and is carried out for a number of reasons. For living persons, age estimation is performed in order to assess whether a child has attained the age of criminal responsibility, in scenarios involving rape, kidnapping or marriage, in premature births, adoption procedures, illegal immigration, pediatric endocrine diseases and orthodontic malocclusion, as well as in circumstances in which the birth certificate is not available or the records are suspect. According to data from the UNHCR (United Nations High Commissioner for Refugees), the number of people seeking refugee status continued to increase in the last years, driven by the w…
Validity of demirjian and nolla methods for dental age estimation for Northeastern Turkish children aged 5?16 years old
2012
Objective: To evaluate the applicability of Demirjian and Nolla methods for northeastern Turkish population. Material and Method: A retrospective study was performed on panoramic radiographs of 673 subjects aged 5–15.9 years. The mean dental age (DA) according to the Demirjian and Nolla methods were compared to the mean chronological age (CA). Results: The mean CA of the study sample was 10.37±2.90 and 10.03±2.81 years for females and males, respectively. Using the Demirjian method, the mean estimated DA was 11.26±3.02 years for females and 10.87±2.96 years for males. For Nolla method, the mean estimated DA was 9.80±3.41 and 9.53±3.14 years for females and males, respectively. The mean diff…
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…
Primary double teeth. A retrospective clinical study of their morphological characteristics and associated anomalies
2000
Aim. To investigate the relationship between morphology and position of double teeth, and the occurrence of other dental anomalies in the same subjects and in their siblings. Sample of children and methods. Fifty-three double teeth in a group of 50 Spanish children were included in the study. All of these children were examined clinically and had radiographs and photographs taken at the time of examination. Twenty-two of the children had a total of 30 siblings who were also examined for the presence of anomalies. Results. Of the 50 subjects, 47 had one and three subjects had two double teeth. Statistically there were no significant differences in occurrence between boys and girls, left and …
Sex estimation by tooth dimension in a contemporary Spanish population.
2020
Aim: Sex determination is a fundamental step in the biologic profile reconstruction of unknown individuals. Teeth are frequently recovered intact, even in case of natural or mass disasters, fires, crashes or accidents. Therefore, they are very valuable in sex determination in a forensic and anthropological context. The objective of this study is to identify a method for sex determination using the mesio-distal widths of permanent teeth, in a contemporary Spanish sample. Method: The mesio-distal dimensions of permanent teeth were obtained from study casts derived from patients seeking treatment at the orthodontic clinic of the Universidad Europea de Valencia. A total of 210 patients were inc…
Decayed, missing and filled teeth and dental anomalies in long term survived leukemic children: a prospective controlled study
2011
Objective: The aim of this prospective controlled study is the comparison between long-term children survived leukaemia and a control group in terms of the decayed, missing or filled permanent teeth (DMFT) and dental anomalies. Study design: Fifty-two long term children survived leukaemia, aged from 8 to 15 years (27 females, 25 males; mean age 11.5 years) were evaluated for the possible effects of the anti-leukaemic therapy on dental development and compared to a control group of 52 healthy children (27 females, 25 males, mean age 11 years). All long-term children who survived were at least 24 months in continuous complete remission. The study of the dental status with a routine oral exami…
Oral health in 6-year-old schoolchildren from Berisso, Argentina : falling far short of WHO goals
2010
Objectives: Dental diseases in children have been reduced in recent decades in developed countries, although trends remain unclear in other countries. Oral healthcare in Argentina is based on demand and depends on a patient's health insurance coverage. The objective of this study was to determine the oral health situation of the population of six-year-olds in Berisso, Buenos Aires province (Argentina). Study design: A cross-sectional observational study was performed on schoolchildren from public and private schools. The following factors were evaluated: DMFT, DMFS, dft, dfs, significant caries (SiC), filled, decayed and missing teeth, and the prevalence of caries in both primary and perman…
Bulk filling of Class II cavities with a dual-cure composite: Effect of curing mode and enamel etching on marginal adaptation.
2014
Objectives: This study attempted to find a simple adhesive restorative technique for class I and II cavities on posterior teeth. Study Design: The tested materials were a self-etching adhesive (Parabond, Coltene/Whaledent) and a dual-cure composite (Paracore, Coltene/Whaledent) used in bulk to restore the cavities. Class II MO cavities were performed and assigned to 4 groups depending on the orthophosphoric acid (H3PO4) conditioning of enamel and polymerization method used (chemical or dual). Specimens were subjected to quantitative marginal analysis before and after thermo-mechanical loading. Results: Higher percentages of marginal adaptation at the total margin length, both before and aft…
