Autopercepção e condições de saúde bucal em gestantes

This study ev aluated oral health indic ators by determining the pr evalence of dental c aries, periodontal diseases, prosthetic conditions and need in pr egnant women; identifi ed self-perceived oral health status and evaluated association bet ween variables. A clinical examination was performed in fi fty pregnant women assisted in the Preventive Dentistry Clinic-FOAr-UNESP using traditional oral health indicators: DMFT, C ommunity Periodontal Index ( CPI) and pr osthetic c onditions. A semi-struc tured questionnair e was applied to identify oral health perception and to collect sociodemographic variables. For data analysis, pregnant women were allocated in three groups according to their oral health perception (good, fair, poor) and compared according to clinical variables by the Kruskal-Wallis and Dunn tests. DMFT was high, all of them showed periodontal changes, most do not use and do not r equire any type of prosthesis; 36% considered their oral appearance as good. There was signifi cant diff erence between groups for the DMFT index and prosthetic need. It may be concluded that despite dental caries experience of pregnant women was found to be high, the prosthetic need have been detected in most of them and the presence of calculus was observed in all the volunteers, the majority considered their oral health status satisfactory.

O uso de rhBMP-2 para aumento ósseo maxilar: relato de caso clínico

The bone resorption in the anterior maxilla, due to its aesthetic importance, can be considered one of the challenges in implant dentistry. Autogenous bone graft is the most indicated bone augmentation procedure, aiming an implant supported rehabilitation.. Alternatively, some other graft procedures can be done with homogenous and xenogenous bone graft, biomaterials and different associations. Additionally to the mentioned biomaterials, the bone morphogenetic protein (BMP), specially the rhBMP-2, which was characterized as a bone osteoinductor, and consecutively, a potential autogenous graft substitute, with previsibility and no necessity of association to other biomaterial. The objective of this study is to present a single case using the rhBMP-2 for bone augmentation.

Considerações gerais sobre prótese fixa adesiva

The success rate of resin-bonded fixed partial dentures is directly related to the adhesive system and the tooth preparation design for good retention. These resin-bonded bridges represent a prosthodontic alternative, based on their costeffectiveness, conservative techniques, and ease of laboratory manufacturing. Through a thorough review of the literature, this study aimed to report on cavity designs, types of materials used, and the advantages and disadvantages of the resin-bonded fixed partial denture. One of significant advantages of the resin-bonded fixed partial dentures is the conservation of the tooth structure, whereas its main disadvantage includes aesthetic limitations, given that the alloy may in fact be visible. Preparation design, cement type, and casting alloy type, as well as surface treatment, are among the factors that influence the longevity of resin-bonded fixed partial dentures. Treatments with resin-bonded fixed partial dentures present a bright outlook regarding the conservation of tooth structures, as well as a high level of success.

Reabilitação oral de paciente com sequela cirúrgica utilizando a técnica da zona neutra: relato de caso clínico

Objective and Case report: The purpose of this paper is to describe the neutral zone technique in a patient with oral deformity on the right labial commissure due to the resection of an oral cancer, enhancing the difficulty resulting from mouth limited opening and the use of tissue conditioner material to determine the neutral zone. Complete denture was obtained through this technique, providing good retention and stability which made functional rehabilitation feasible to patient of his or her masticatory function. Final considerations: The neutral zone technique in complete dentures will determine a specific intraoral area for tooth position and denture base contour where the forces generated by lips, cheeks and tongue are neutralized. The objective of this technique is to provide an alternative approach for patients who presented an historic instability of lower complete denture: atrophic ridge, oral deformities and also with disorder problems. An oral rehabilitation using this technique improves comfort to the patient providing retention and stability of mandibular complete dentures.

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.

Reconstrução imediata de fenestração peri-implantar com enxerto autógeno em bloco de ramo mandibular

Alveolar wall fenestrations are common during implant placement. The aim of this paper is to report a case where a peri-implant bone fenestration was reconstructed immediately after implant placement by an autogenous mandibular bone block. A male patient was referred to the Department of Surgical and Integrated Clinics to substitute his Kennedy´s Class IV removable partial denture for an implantsupported fixed prosthesis. A peri-implant bone fenestration at the buccal wall was seen at the region of 12, being reconstructed by a mandibular bone block secured by a bicortical screw. Six months later the surgical procedures, an implant-supported complete fixed partial prosthesis was developed. The autogenous bone block harvested from the mandibular ramus was a safe alternative to reconstruct the peri-implant bone defect such as fenestration types.

Fechamento de fístula buco-sinusal usando tecido adiposo bucal

The Oro-antral Fistula is a common pathologic event, which occurs an opening or communication of the maxillary sinus with the oral cavity through dental extractions of upper posterior elements whose roots have close relationship with the maxillary sinus. This study aims to clarify the Surgeon Dentist about the possible etiological factors responsible for Oro-antral Communication, to identify its clinical and radiographic signs, to explain the Buccal Fat Pad’s anatomy and functioning and to describe the surgical technique adopted front of these cases. For this, the authors present a case of a patient who had a fistula in the region where there was a dental extraction of the upper posterior element. The treatment of Oro-antral Fistula using the buccal fat pad provides to be a safe and effective surgical method, because this element presents a rich blood supply and easy access. Many authors have found that this method have a broad application, large index of success, lower risk of infection, provides a comfortable post-operative for the patient. However, it needs to be done properly so that you have minimum incidence of failures, and this requires some caution on the part of professional.

Impacto do uso de fita adesiva na qualidade de vida de pacientes institucionalizados e usuários de próteses totais convencionais

Objective: Evaluate the impact of the use of strip adhesive over the quality of life of institutionalized patients and wearers of complete dentures. Material and method: Twenty-nine institutionalized patients wearers of complete denture were selected to this study and after a clinical exam, a questionnaire (adjusted and based upon the index of Oral Health Impact Profile and Oral Health-Related Quality of Life, OHIP and OHQOL) was applied to evaluate issues related to epidemiological conditions (gender and age), quality of life (pain, discomfort, functional limitations, phonetic, social, psychological and esthetic), taste and notion of implant treatment. Following this part, the patients received instruction to use the strips adhesives (Corega Fita Adesiva, Glaxo-Smith-Kline, Rio de Janeiro, Brazil), considering three in maxillary prosthesis and two in the lower prosthesis during a period of 30 days. After this period, all the patients were recall and the questionnaire was reapplied; add some adhesive performance questions, to compare the results before and after the adhesive use in terms of percentage. Result: After the adhesive strips use there were improvement of the functional, social and physcological limitation aspects, but without percentual increasement of phonetic and esthetics aspects. The results showed 65.5% of the answers stating adhesive maintenance between 6-12 hours, easy removal (68.9%), and without change the taste (89.6%). The notion for implant treatment was decreased changing from 75.8 to 37.9% after the adhesive use. Conclusion: The results enhanced a positive impact over quality of life of the respondents after the strip adhesive use, showing decrease of pain and discomfort, mainly of inferior dental prosthesis.
