Perfil das condições sistêmicas e bucais de usuários de próteses removíveis atendidos em um Serviço de Medicina Bucal

A presença de doenças sistêmicas, uso de medicamentos, e uso de próteses removíveis, entre outros fatores, podem alterar o equilíbrio fisiológico da cavidade bucal favorecendo o estabelecimento de diversas alterações e/ou patologias bucais. Assim, o estudo das prevalências destes fatores, nos pacientes odontológicos, tornam-se importantes pois devem ser considerados para elaborar o diagnóstico e definir a conduta terapêutica. Com o objetivo de delinear um perfil, avaliamos os prontuários de 500 usuários de próteses removíveis atendidos no Serviço de Medicina Bucal da Faculdade de Odontologia de Araraquara - UNESP. Analisamos os dados referentes a: características da população e das próteses removíveis, prevalência das doenças sistêmicas, uso de medicamentos e diagnóstico final das patologias ou alterações bucais. Os resultados obtidos nos permitem concluir que a maioria (74%) dos usuários de próteses removíveis eram mulheres brancas; metade da população pertencia a faixa etária de 41 a 60 anos e, quase a metade (49,2%) usava a combinação de prótese total superior e inferior. As doenças sistêmicas foram relatadas por 57,2% da amostra e a prevalência maior foi de doenças do sistema cardiovascular (25,4%). A maioria (60,4%) da população relatou uso de medicamentos e, dentre os mais freqüentes, a prevalência maior foram dos cardiovasculares (26,4%). A prevalência de patologias ou alterações bucais foi de 99,6%, sendo as relacionadas ao uso de próteses removíveis as mais freqüentes. Dentre estas, a candidose crônica atrófica ocorreu em 81,8% da população estudada e a hiperplasia fibrosa em 29,2%.

Considerações clínicas em implantes imediatos

The biological principles of osseointegration caused the rehabilitation treatment with osseointegrated implant become a safe, well alternative accepted by the dental community for the high success rate, allowing the preparation of functional and aesthetic prostheses in edentulous and partial patients. We passed the initial phase of functional vision for an aesthetic approach, too, depending on the demands of the patient and the quest for excellence by professionals. Over these last years, implant treatment has undergone many changes in surgical and prosthetic protocols. The less invasive surgical techniques and the development of restorative materials, especially ceramics allow the prosthetic rehabilitation of high functional quality and aesthetics. The installation of implants in sockets immediately after extraction of teeth involved by fracture, periodontal disease, endodontic lesions, is part of the arsenal of techniques for rehabilitating a number of advantages that we get to the outcome of multidisciplinary treatment. For this, we must consider several criteria in its planning as a fundamental unit, adjacent teeth, multiple losses, system, form and number of implants, type of retention of the prosthesis components, the patient expectation of the outcome perspective, gingival biotype, standard of ridge resorption, the smile line, etc. occlusal analysis. With the three-dimensional placement of the implant can immediately join the biological processes of repair of the socket, implant osseointegration, speeding treatment time. Much has been made by companies in the surface treatment of endosseous implants to be osseointegration shortened and restorative procedures started earlier, bringing benefits to the patient and professional. Among the main advantages we can emphasize the preservation of the structures adjacent to the teeth replaced, minor resorption of bone tissue involved...

Subjective assessment of adhesives usage by complete denture wearers in a brazilian population

The information about the knowledge and usage of denture adhesives is still limited, particularly in Brazilian populations. Objective: The purpose of this study was to investigate the aspects related to the use or nonuse of denture adhesives by complete denture wearers. Material and method: Questionnaires were applied to 100 bimaxillary complete denture wearers concerning their usage of denture adhesives. The survey was carried out according to three categories: those who had never tried adhesive, those who had tried adhesive at least once but no longer used it, and those who currently used it. Result: Of the 100 participants, 80% had never tried adhesives, 16% had tried at least once but no longer used it and 4% had used on a regular basis. Conclusion: Within the limitations of this study, the results of this subjective assessment suggest that within the participants that had never tried adhesives, 77.5% inform that the adhesive is not needed, and all participants who regularly use it inform its efficiency.

Estudo prospectivo sobre a utilização de próteses totais implantossuportadas em pacientes edêntulos

The objective of this study was to evaluate the impact of replacing conventional mandibular complete dentures by complete fixed dentures on the oral health-related quality of life and kinesiographic parameters of maxillary edentulous patients. Material and Methods: edentulous patients (n = 16) received one set of new complete dentures and after the intraoral adjustments and adaptation period (30 days), the Brazilian version of Oral Health Impact Profile for assessing edentulous subjects (Ohip-Edent) was used to evaluate the oral health-related quality of life (OHQOL) of the participants. Additionally, the kinesiograph instrument K6-I (Myotronics Research Inc., Seattle, WA) was used to record opening and closure range of movement, mandibular movement, and the pattern of maxillary complete denture movement on chewing. Afterwards, the patients had their mandibular complete dentures replaced by a complete fixed denture and the same evaluation protocol was performed after 3 and 6 months. Ohip-Edent responses were analyzed using Wilcoxon's test for repeated measures (α = .05) and Kinesiographic data using the Student´s t test (α = .05). Results: The Ohip-Edent showed an improvement of general oral health-related quality of life after 3 and 6 months of the treatment with complete fixed dentures. Kinesiographic recordings revealed a significant increase on maximum mandibular movements of vertical opening and no differences for the movement of the maxillary complete denture on chewing after treatment with complete fixed dentures was observed. Conclusion: the installation of complete fixed dentures improved the OHQOL and changed mandibular movements, with increases in vertical amplitude of maximal opening.

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.
