Perfil dos pacientes geriátricos portadores de prótese total

This study had the purpose to evaluate 240 records of patients assisted by the disci¬pline of Complete Denture course of the Dental Scholl - Araçatuba Campus - UNESP, in the period from 1980 to 2001 , when each patient was sixty years old or more at the time of the rehabilitation. The characteristics analyzed were the origin city , the sex , the marital status, general health , the color and commercial mark of the selected artificial teeth and the type of prosthesisEste estudo teve como propósito avaliar uma amostra geriátrica de 240 prontuários de pacientes, atendidos pela disciplina de Prótese Total da Faculdade de Odontologia de Arkatuba- UNESP, no período de 1980 a 2001, considerando-se que cada individuo apresentava sessenta anos ou mais na época de seu atendimento.As características de cada paciente foram analisadas quanto a cidade de origem, o sexo, o estado civil, estado de sande geral,a cor dos dentes selecionados e o tipo de prótese confeccionada. Concluiu-se que a maioria dos pacientes pertenciam ao sexo feminino, que a doença mais frequente foi a hipertensão arterial e que o tipo de Prótese mais confeccionada foi a bimaxilar

Evaluation of biomaterials with and without platelet-rich plasma: a histometric study using beagle dogs

Abstract Aim: To compare the alveolar bone repair process using biomaterial in dogs with and without the incorporation of platelet-rich plasma. Methods: Six beagles were used. Bilateral extractions of the three mandibular premolars were performed. Bio-Gen(r) was applied in the first alveolus, the clot was maintained in the second alveolus and Genox(r) was applied to the third alveolus. PRP was added to all alveoli on the left side only. The dogs were submitted to euthanasia after 30, 60 and 90 days and submitted to histological analysis for the determination of mean area of new bone formation. Tukey's post test was used in the statistical analysis. Results: Significant increase in bone formation occurred in Bio-Gen(r) + PRP when compared with the other groups at 30 and 90 days. In the evaluation at 60 days, no statistically significant differences among the groups were found. Conclusions: The Bio-Gen(r) biomaterial led to the best bone repair and the combination of platelet-rich plasma accelerated the repair process

Sealing agent reduces formation of single and dual-species biofilms of Candida albicans and Enterococcus faecalis on screw joints at the abutment/implant interface.

The aim of this research was to evaluate the efficacy of a commercial sealing agent at the abutment/implant interface against microleakage of single and dual-species biofilms of Candida albicans and Enterococcus faecalis into external hexagon (EH) and Morse taper (MT) prosthetic connections. A total of 216 samples of implants and their abutments were tested. Six groups (n = 36) were evaluated based on biofilm and period of incubation (7 and 14 days). The implant connections EH and MT (n = 18) were divided according to the use of the material (n = 9) (EH-T and MT-T: with the sealing agent; EH-C and MT-C: control). The biofilms were analyzed by microbial counting (CFU/mL) and SEM analysis and photographs of the material in the screw joints were also taken. Data were analyzed by Student t test, two-way ANOVA and Bonferroni test. For the single-species biofilms, there was a significant reduction in the growth of E. faecalis when compared MT-C and MT-T or EH-C and EH-T at 7 and 14 days. The same was observed for C. albicans biofilms. For dual-species biofilms of E. faecalis and C. albicans, the sealing agent was more effective in preventing microbial infiltration into the MT connection at 14 days, while microbial infiltration did not occur into EH connections even in absence of the sealing agent for both periods of evaluation. Overall, these data suggest that the presence of the sealing agent reduces or eliminates the microleakage of E. faecalis and C. albicans biofilms into the implants regardless of the period of incubation

Avaliação da alteração dimensional e porosidades em resinas acrílicas entre métodos de polimerização convencional e por microondas

Dental perforations are artificial voids which communicate the root canal system with the adjacent tissue. Despite the fact they may cause irreversible damage, the proper therapeutic approach enhance prognosis. Besides an accurate diagnose, a biocompatible and tight seal is desirable to attain success. Among other materials, Mineral Trioxide Aggregate (MTA), due to its excellent biological, physical and chemical properties, brings a new perspective in thThe proposit of this study was to evaluate the linear dimensional change and the ocorrency or not of porosities in four types of acrylic resin for denture bases. There were analysed the acrylic resins of trademarks: Classico, QC 20, Vipi Dent and Classico Onda Cryl. The polimerization methods differed among: conventionals, according to manufacturer’s recomendations, and by microwave energy, with or without chemical polishing, in proper equipment of Termotron trademark. treatment of perforations.O propósito deste estudo foi avaliar a alteração dimensional linear e ocorrência ou não de porosidades em quatro tipos de resina acrílicas. Foram analisadas as resinas acrílicas de marca comercial: Clássico, QC 20, Vipi Dent e Clássico Onda Cryl. Os métodos de polimerização variaram entre: convencionais, recomendados pelos frabricantes, e através de energia de microondas, com ou sem polimento químico, em aparelho próprio da marca comercial Termotron
