title: Parental perception versus the presumption of the occurrence of dentoalveolar trauma in their children

description: ABSTRACT Objective: This cross-sectional, observational study sought to ascertain the perception of parents vis-à-vis the presumption of a dentoalveolar trauma, with regard to the main sequelae, social relationships, expected reactions of the children, and the feelings of the child. Methods: A total of 74 parents were selected at random, who were presented with six color photographs taken from a book, having the clinical appearance of traumatic injury. The responses were recorded with the aid of a voice recorder and were transcribed and stratified using semantic approximation. The data were tabulated using the SPSS software program and evaluated using descriptive statistics. Results: The main sequelae ascribed to dentoalveolar trauma by the parents were as follows: loss of the tooth (43%) and damage to the permanent tooth (18%). The majority of parents believed there would be no change in terms of the children’s relationship with their parents (68.9%), while for 54.1%, there might be some alienation by children in the neighborhood, and for 90.5%, schoolchildren might tease or make fun of them. Of the expected reactions, 86.5% of parents believed their child would feel differently in relation to their friends, because of their appearance. With regard to feelings, for 85.1%, the trauma could lead to the children experiencing shame or embarrassment, 79.7% replied shyness or introversion, and 60.8% sadness. Conclusion: It was concluded that the loss of a tooth and the risk of involvement of the permanent successor tooth germ were the main sequelae ascribed by the parents. Dentoalveolar trauma may have a detrimental effect on the social relationships of the children with others in the neighborhood, and mainly at school, and they may feel differently towards their friends on account of their appearance. Moreover, the children may experience shame or embarrassment, shyness or introversion, and sadness.

title: Dental bleaching gels do not alter the surface roughness and microhardness of feldspathic porcelain

description: ABSTRACT Objective: To evaluate whether two different bleaching gels affect the microhardness and surface roughness of feldspathic ceramic specimens, in vitro. Methods: A total of 48 feldspathic porcelain IPS In Line (Ivoclar-Vivadent) discs (16/treatment group) were immersed in distilled water (Group I, Untreated control, UN), or treated with the bleaching gels: Opalescence (15% carbamide peroxide; OPA) and Opalescence Xtra Boost (38%hydrogen peroxide; OPAXB), for 1h or 6h daily for 14 days. Surface roughness (Ra) and microhardness (Knoop, or KNP) measurements were made before and after treatment, and data were subjected to statistical analysis by paired Student’s t-test (p &lt; 0.05). Results: Treatments using Opalescence and Opalescence Xtra Boost did not altered surface roughness (p=0.6199861) or microhardness (p=0.14286744) of the feldspathic porcelain tested in this study. Conclusion: Bleaching treatments using Opalescence and Opalescence Xtra Boost may be suitable for treatment in patients having ceramic prosthodontic treatment. Conclusion: Bleaching treatments using Opalescence and Opalescence Xtra Boost may be suitable for treatment in patients having ceramic prosthodontic treatment.

title: Quality of models supplied to dental laboratories for the fabrication of partial removable denture framework

description: ABSTRACT Objective The aim of this study was to evaluate the models and plannings of metallic framework of removable partial prosthesis sent to dental laboratories in the city of Recife. Methods: The physical and technical conditions of plaster models were sent by the dentists to 4 dental laboratories. All models were examined, photographed and recorded on a form according to the research objective. Results: A total number of 235 models sent by dental surgeons were used to prepare the metallic structure, in which none of the models presented surveying nor the path of insertion. Out of the 235 models, 41 (17.44%) presented serious failures, such as positive and negative bubbles, broken dental elements, direct retainers and damaged edentulous areas. With respect to the planning, only 22 (9.35%) models were presented with the metallic framework planning, but in an unsatisfactory way. Regarding mouth preparation, no model presented a guide plane, and only 6.8% of models had rests seats, but incorrectly prepared. Conclusion: The models evaluated presented poor quality, lack of planning and no mouth preparation. This shows the need for dental surgeons to be aware of the appropriate prosthesis models and plannings in order to ensure a satisfactory and long-term rehabilitation of the patient, as well as preserving the remaining mouth structures.

title: Dental management of a child with a rare bone disorder: a case report with a six-year follow up

description: ABSTRACT Osteogenesis imperfecta is a rare genetic disorder involving abnormal type I collagen composition that compromises bone and collagen-rich tissues. Individuals with Osteogenesis imperfecta exhibit oral and systemic abnormalities, including dentinogenesis imperfect. The purpose of the review is to report a clinical case of a nine-year-old boy diagnosed with Osteogenesis Imperfecta type III, focusing on dental and occlusal aspects. The case report was developed at the outpatient clinic at the School of Dentistry of the Federal University of Minas Gerais, in Southeastern of Brazil. The clinical oral examination revealed Angle Class III malocclusion and anterior crossbite. It was also observed the presence of dentinogenesis imperfect in both primary and permanent teeth. Radiographic analysis showed the presence of completed obliterated pulp chambers in both dentitions. Dental treatment included oral hygiene counseling, dental extraction, fluoride therapy and restorations. The child was followed up for a period of six years and then referred to the orthodontic outpatient clinic at the same university for the treatment of malocclusion. Early dental care is important to the prevention or interception of oral diseases, such as dentinogenesis imperfect and malocclusion, as well as the improvement of dental esthetics in cases of Osteogenesis Imperfecta.

title: Use of dental services by psychoactive substances users at the Psychosocial Alcohol and Drug Care Centers in the Greater Vitoria area, ES

description: ABSTRACT Objective The use of and access to dental services in Brazil are unevenly distributed, despite governmental efforts to make the national health system universal and egalitarian. This study aims to evaluate the access to and use of dental services by psychoactive substances users at the Centros de Atenção Psicossocial Álcool e Drogas (Psychosocial Alcohol and Drug Care Centers) in the Greater Vitoria area, ES. Methods A transversal study was conducted with 280 participants. Five scripts were used for data collection, one for socio-demographic data and health perception, another for oral health, along with the Oral Health Impact Profile, the Alcohol Smoking and Substance Involvement Screening Test, and the World Health Organization Quality of Lifeinstrument. Data were displayed infrequency tables. The association between demographic factors with drug use, frequency of use and quality of life was tested using Fisher’s test. The Odds Ratio was used to determine the strength of the association. Results Dental services were used 32.14% of the study population and individuals at high risk for crack dependence were 2.3 times more likely not to use dental services in previous 6 months. Conclusion The study population showed a satisfactory utilization of the dental services offered while individuals at higher risk of crack addiction used them much less frequently.

title: Do denture teeth dimensions match natural anterior teeth?

description: ABSTRACT Objective To compare dimensions of natural maxillary anterior teeth and several denture teeth molds and also address differences between genders. Methods A single examiner with a digital caliper measured dental casts of 41 males and 55 females in order to determine CIW (central incisor width), CIL (central incisor length) and WS (width of anterior teeth on a straight line). In addition, WC (width of anterior teeth on a curve) was measured with a flexible ruler. These parameters were also observed on three denture teeth mold charts: Premium Pala, Vivodent and Trilux. The comparison between genders was analyzed using Student’s t-test (?=.05), while absolute frequencies within several ranges were used to compare natural and denture teeth. Results CIW, CIL, WS and WC obtained from males were significantly higher than those found for females (p&lt;0.05). CIW of nearly half of natural and denture teeth were within 8.0–8.5 mm. Almost half of natural teeth presented CIL values within 10.6–11 mm, while the highest frequency of denture teeth was observed within 9.6–10 mm. The majority of natural and denture teeth presented WS values within 42 to 49 mm. Only one denture teeth chart described WC values, which were mainly observed within 44–51 mm, while the majority of WC values obtained from natural teeth ranged from 48 to 55 mm. Conclusion Some commercially available denture teeth present dimensions not observed in natural teeth. Teeth dimensions in function of gender differences must be considered when selecting denture teeth.

title: Oral conditions and the impact on quality of life of morbidly obese and bariatric patients

description: ABSTRACT Objective The aim was to evaluate the prevalence of dental caries, periodontal disease and edentulism in morbidly obese and bariatric patients, and to verify the oral health impact on quality of life. Methods We evaluated 33 morbidly obese patients (G1) and 50 patients submitted to bariatric surgery (G2). The DMFT, CPI, prosthetic status and prosthetic need for edentulism were used to analyze oral conditions. The impact of oral health on quality of life was assessed using the OIDP questionnaire. Results CPOD were G1: 9.0±7.0 and G2: 13.3±8.0 (p= 0.020). The dental calculus was the worst periodontal condition G1: 72.7% and G2: 80.0% (p= 0.752). The majority of G1 and G2 patients did not use (p = 0.878) and did not need (p= 0.132) dental prosthesis. The mean of OIDP was G1: 11.2±23.8 and G2: 14.16±23.8 (p= 0.089). Conclusion It concluded that bariatric patients have a higher prevalence of dental caries and the need for dental prostheses is related to the impact of oral health on the quality of life of obese patients.

title: Prevalence of dental anomalies and bone alterations in children’s panoramic radiographies

description: ABSTRACT Objective To verify the prevalence of dental anomalies in terms of number, position and shape, and the presence of bone alterations, through analysis of panoramic radiographs. Methods This study evaluated dental anomalies and bone alterations in children aged 6 to 12 years-old, detected on panoramic radiographies recorded in the radiographic database of the Federal University of Espírito Santo between 2012 and 2016. Clinical and demographic information were registered. Dental records were retrieved to obtain the medical history involving syndromes or other diseases that may interfere with the anomalies and alterations. Chi-square and exact Fischer’s statistical tests were performed. Results There were alterations in 83 out of 301 panoramic radiographs analyzed. There were 169 anomalies or alterations (mean of 2,04±1,38 anomalies/patient), involving 201 teeth. The most prevalent anomaly was tooth impaction (26.63%), which affected the canines more frequently, followed by hypodontia (24.26%), more often found in the second premolar, and both affected mostly females. Hyperdontia and radiolucent lesions showed the same prevalence (18.93%), the most affected teeth were those of the anterosuperior region and the first mandibular molars, respectively. The least prevalent anomalies were dilaceration (7.69%), taurodontism (2.37%) and radiopaque lesions (1.18%). Bone alterations were significantly more found in mandible and in the posterior region, which confirms the prevalence in the lower molars. Conclusion Although there was no statistically significant difference regarding sex, there was a high prevalence of anomalies and alterations in our study population, which indicates the importance of its diagnosis by means of a panoramic x-ray examination.
