Dor orofacial e qualidade de vida de adultos

To determine the prevalence and intensity of orofacial pain in adults that participated in a health program at Ribeirão Preto. Methodology: The study was conducted by a self-administered questionnaire, with 19 questions in 99 people aged 18 to 66 years. The method used for data collection was the index Oral Impacton Daily Performances (OIDP), which evaluated the six months preceding the survey, pain experiences in the mouth, teeth or dentures and how these factors interfere with daily activities. Statistical analysis was performed using Epi Info version 3.4. Results: The majority of the adults who participated in this survey (52.5%) reported having an excellent or good oral health, reported having problems with their teeth (60.6%), no problems with the gums (77.8%), no bad taste in mouth (77.8%) or bad breath (77.8%). Among the participants of the study, 56.6% felt orofacial pain in the last six months and the pain were more frequently caused by cold or hot liquids (30.3%), spontaneous pain (17.2%), during the mouth opening (17.2%), pain in the face (13.1%) and ATM (13.1%). Regarding the severity rate, the highest proportion varied from mild to moderate. Conclusions: Even observing a low severity of orofacial pain, its prevalence was high, which probably has a negative effect on life quality of these people.

Responsabilidade do profissional da saúde no esclarecimento equivocado do paciente para obter o seu consentimento livre e esclarecido

Ao paciente é necessário fornecer esclarecimentos sobre as possibilidades terapêuticas, apresentando os riscos, benefícios, prognóstico e custos de cada alternativa possível e indicada. Esta é uma determinação ética e jurídica. Não obstante, o profissional da saúde detém o conhecimento clínico/técnico/científico, e determina quais informações serão (ou não) fornecidas. O paciente decide submeter-se a um tratamento, fornecendo o seu Consentimento Livre e Esclarecido com base nos dados a ele apresentados. Infelizmente, pode ocorrer de alguns profissionais não fornecerem todas as informações necessárias a uma tomada de decisão esclarecida ou, depois de obtido o consentimento do paciente, apresentarem-lhe informação que cause sua desistência do tratamento inicialmente aceito. Esta última informação, se pertinente, e não se tratando de fato superveniente, deveria ter sido fornecida inicialmente. Porém, a informação pode não ser de todo verdadeira, e levar o paciente a decidir baseado, por exemplo, em riscos apresentados e mensurados de forma equivocada. A reabilitação crânio-facial da Articulação Têmporo-Mandibular (ATM), por meio de prótese de ATM, é indicada em muitas situações. Amiúde, pacientes que necessitam de tais próteses apresentam problemas funcionais e estéticos; a expectativa gerada com a reabilitação é grande. Este trabalho apresenta um caso e discute questões éticas e legais, incluindo a responsabilidade civil, do fornecimento parcial e inadequado de esclarecimentos a um paciente.

Associação de prótese fixa, implantes e estética periodontal para reabilitação de pacientes parcialmente edêntulos

Periodontitis is a chronic inflammatory disease that results in the destruction of teeth and their supporting tissues with subsequent tooth loss. The replacement of missing teeth for implant-supported restorations has proven to be a highly predictable treatment method with good long-term prognosis. However, some consequences of tooth loss prevents dental implant placement in an ideal position, where regenerative procedures are necessary for this type of rehabilitation. Less invasive procedures such as conventional prosthesis emerge as a therapeutic option in cases where there is enough bone structure for implants and patient´s non-acceptance for invasive procedures. Thus, this paper aims to present the resolution of rehabilitation through a noninvasive and multidisciplinary treatment. One female patient referred to the clinic presented maladaptive bilateral mandibular fixed prostheses, endodontic lesions, gingival recession, and root sensitivity. For proper resolution of this case, an association among osseointegrated implants, fixed partial prosthesis, tooth extraction, and aesthetic periodontal procedures with the use of subepithelial connective tissue graft was proposed. After two years, the patient shows excellent aesthetics and chewing. Within the limits of this scenario, this paper discusses the various factors that may affect the choice of a particular treatment modality for the rehabilitation of edentulous single spaces.

Reabilitação estético-funcional sobre implantes agulhados e endósseos

This report shows the resolution of a case study whose aim was promote the aesthetic and functional rehabilitation of upper left hemi-arch over endosseous and needle implant prostheses. To improve the position of the needle implants, we performed the bucco-palatal bending of needles splinting them with composite resin; we removed the screwed implant prosthesis in the regions of the premolars (24 and 25) and molar (26). The mini-abutments of the last two implants were replaced, and in the first premolar and canine, we used cemented abutments due to implant angulation having planned soldering because of implant size and contact with one needle implant that could interfere with intimate contact bone/implant damaging biomechanics. Pick-up impressions were performed with an open tray, using a retractor cord in the needle implants and respective transfer copings. Therefore, models were related on semi-adjustable articulator after a face-bow recording and interocclusal indexes. After working cast fabrication and try-in of infra-structures, these were adjusted and related into the articulator again. Then, after ceramic build-up, adjustments, finishing, and torque, chemically-activated resin cement was applied on units 21 to 24. At the end of the case, we concluded that a good aesthetic and functional rehabilitation depends on thorough knowledge of techniques for each clinical situation.

Importância do tratamento estético periodontal na reabilitação protética

Gingival recession is a common deformity that affects a large number of people. This condition is frequently associated with esthetic complains and may lead to dental hypersensitivity. Thus, various surgical procedures have been proposed to provide root coverage. Since the 1950s, free and pedicle gingival grafts have been greatly used for treating gingival recession. However, after the 1985 Miller gingival recession classification, and with the development of other appropriated techniques that use subepithelial connective tissue grafts, gingival recession treatments have resulted in more predictable outcomes, especially with respect to Class I and II sites, i.e., in the absence of interproximal bone loss. This article reported the importance of aesthetical periodontal treatment in the prosthetic rehabilitation of a patient with a class I gingival recession with 3 mm of vertical extension in the superior canine. The treatment plan consisted of root coverage using subepithelial connective tissue graft (SCTG) associated with construction of new prosthesis.

Técnica estrutural: confecção de pilar personalizado cerâmico para otimizar a estética

Na reabilitação protética com implantes, a reconstituição das características anatômicas do tecido peri-implantar é fundamental para a obtenção de uma estética ótima. Como os componentes metálicos não transmitem a luz, fazem com que os pacientes com fenótipos gengivais finos apresentem uma coloração escurecida, resultante da limitação estética desses componentes. Pilares cerâmicos (alumina ou zircônia) têm sido utilizados para resolver esse problema, os quais possibilitam a complementação com próteses metal free. A indústria fornece, para alguns sistemas, componentes pré-fabricados cerâmicos a serem personalizados por desgastes e componentes personalizados confeccionados com sistemas CAD/CAM e CAD/MAN. Tendo em vista as limitações de algumas das conexões desses componentes, o objetivo desse estudo é apresentar a técnica laboratorial para confecção de um pilar personalizado cerâmico realizado sobre pilar UCLA de sobrefundição. Concluiu-se que a utilização da cerâmica feldspática proporciona ótima estética, boa transparência, resistência mecânica, baixo custo, melhor capacidade adesiva, com utilização de cimentos resinosos, e, principalmente, técnica de amplo domínio dos laboratórios.

Impacto dos problemas de saúde bucal na qualidade de vida de gestantes

Objectives: 1) to evaluate the impact of oral health problems on the quality of life of pregnant women by the simplified Oral Health Impact Profile (OHIP-14) questionnaire as well by the presence of dental caries, periodontal disease and denture use/need; 2) to correlate the sociodemographic variables and the oral health conditions revealed in the clinical examinations with the OHIP-14. Method: In addition to the application of the OHIP-14 questionnaire, clinical examination of the oral conditions (CPI - community periodontal index, DMFT and prosthetic evaluation) was performed on 51 pregnant women, who sought dental treatment between April 2008 and August 2010 at the Preventive Dentistry Clinic. Descriptive analyses were made for sample characterization, bivariate analysis (chi-square or Fisher’s exact tests) and multiple logistic regressions at a 5% significance level to assess the correlation between the impact of oral health on the quality of life of pregnant women and the socio-demographic and clinical variables. Results: The OHIP-14 data showed a lesser impact of oral health on the women’s quality of life. The mean DMFT was 12.8; 70.6% of the pregnant women presented dental calculus and 58.8% needed prostheses. The association between OHIP-14 data and last dental visit and DMFT remained in the final regression model (p<0.05). Conclusion: Caries experience of the pregnant women was considered high. Most of them needed prostheses and presented dental calculus. The OHIP-14 presented a low impact on this population and was significantly influenced by the last dental visit and the DMFT index.

Estudo de propriedades da resina acrílica termoativada por energia de micro-ondas frente às variações nos procedimentos de inclusão

On heat cured acrylic resins by microwaves energy the action of electromagnetic waves on methylmethacrylate promote the polymerization process. However, part of this energy is absorbed by the gypsum present in the flask and the function of this gypsum is to maintain the characteristics of specimen, nevertheless is unknown in the literature as the amount of water present in this gypsum affects the characteristics of acrylic resin. The proposal of this study was verified if dried gypsum influenced in some properties of the acrylic resins thermally activated by microwaves: presence of porosity, microhardness, roughness, flexural strength and dimensional change. Two different types of acrylic resin for complete denture were utilized: Lucitone 550 e Vipi-Wave and groups were formed: Lucitone 550, polymerization by microwave energy without gypsum treatment; Lucitone 550, polymerization by microwave energy with pretreatment gypsum; Vipi-Wave by microwave energy without gypsum treatment; Vipi Wave, polymerization by microwave energy with pretreatment gypsum; Lucitone 550 control group polymerization in hot water bath. For both situations were performed analysis of microhardness and porosity three different metallic shaped specimens were formed with followed dimensions: 2,0x2,0x2,0cm (8cm3); 2,0x2,0x1,0 (4cm3) e 2,0x2,0x0,5 (2cm3). Standardized wax specimens was used to prepare groups (n=9) and included in glass fiber flasks. The gypsum dry was made by microwave oven cycle (10min and 600W) and then the flasks were maintained in dry oven during two hours. Polymerizations of specimens were made and then polished. Wax patterns #7 obtained from the metal were embedded in plastic flask and following the processes of pressing and polymerization of the resin according to established groups. To evaluate the flexural strength, specimens 65mm x 10mm x 3.0mm from metallic patterns in bar format were made. ...

Estudo clínico comparativo da manutenção do aprofundamento de sulco nas vestibuloplastias mandibulares, através das técnicas de tuneilização submucosa e epitelização secundária

For some time, oral surgeons have tried several surgical procedures to improve the alveolar ridge for prosthetic appliance construction. The techniques used for this purpose are divided into four groups: submucosal vestibuloplasty; secondary epithelization; soft tissue grafting and transpositional flaps. Twenty patients who had problems to wear dentures due to unsatisfactory retention and stability were selected at the Oral and MaxilloFacial Surgery and Traumatology Clinic of Dental School of São José dos Campos. They were divided in two groups and operated by submucosal vestibuloplasty using stents and secondary epithelization vestibuloplasty by Clark's technique and were evaluated twelve months after operations in relationship of the sulcus depth. The results were obtained by clinical and radiological examination before and after surgery, and they are similar to those found in the literature reaching satisfactory functional judgement
