The influence of auditory and visual information on the neuromuscular control of chewing crispy food.

The influence of auditory and/or visual information on the neuromuscular control of chewing a crispy food was investigated. Participants chewed biscuits of three different levels of crispness under four experimental conditions: no masking, auditory masking, visual masking, and auditory plus visual masking. The order of the four masking condition blocks was randomized. The sound of chewing was masked by loud sounds on a headphone, and visual masking of the food was achieved by closing the eyes. Mechanical tests were performed on the biscuits to determine their characteristics, yield force, and sound production. Skull vibration, jaw-muscle activity, and jaw movement were measured while the subjects chewed and swallowed the food. Auditory and/or visual masking did not have a significant effect on skull vibration, muscle activity, and number of chewing cycles until swallowing. However, auditory and/or visual masking significantly increased the chewing cycle duration, but only for the participants who started the experiments with auditory and/or visual masking. The other participants were not influenced by masking. The memory of the unmodified stimuli helped these subjects to maintain their habitual chewing rate in later trials.

Oral health impact profile and prosthetic condition in edentulous patients rehabilitated with implant-supported overdentures and fixed prostheses.

The complexity of rehabilitation for totally edentulous patients makes it necessary to devise treatment strategies that meet the patients' expectations in terms of function, esthetic, psychological, and social aspects. The aim of this study was to i) compare the satisfaction of edentulous patients who had been rehabilitated with implant-supported overdentures and fixed prostheses in the mandible, and ii) assess the technical aspects of the prostheses in relation to patient satisfaction. This was a cross-sectional study involving 30 patients, 15 of whom had been rehabilitated with implant-supported overdentures and 15 who had been treated with fixed prostheses. The patients answered the OHIP-EDENT questionnaire, validated for the Brazilian Portuguese language, to assess satisfaction. Also, patients underwent clinical examination to assess the condition of their prostheses. Statistical analysis using the Mann-Whitney U-test revealed no significant differences in satisfaction between patients with overdentures and those with fixed prostheses. Likewise, Fisher's exact test demonstrated no significant differences in patient satisfaction concerning the condition of the prostheses as evaluated by the prosthodontist. It was concluded that both types of prostheses were perceived as being equally satisfactory by edentulous patients, and that the condition of the prostheses did not influence individual satisfaction in terms of rehabilitation.

Prótese fixa maxilar sobre implantes tipo protocolo modificada: gengiva destacável retida por encaixes / Modified implant-supported fixed maxillary prosthesis: removable gingival veneer retained with attachments

Este trabalho relata um caso clínico de reabilitação protética dental em um paciente edêntulo total superior com prótese fixa tipo protocolo sobre seis implantes, porém modificada com o acréscimo de uma gengiva destacável e retida por encaixes de semiprecisão. Esta alternativa reabilitadora fornece ao paciente a funcionalidade e o conforto dos dentes fixos, bem como mantém a estética facial pelo apoio do lábio, mantém fonação adequada e possibilita correta higiene peri-implantar e da prótese, através de gengiva destacável retida por encaixes. Concluímos que as reabilitações fixas maxilares sobre implantes do tipo protocolo, modificadas pelo acréscimo de uma gengiva destacável, são uma ótima alternativa para os casos de severa atrofia vestibular do rebordo alveolar da maxila...

This study reports a clinical case of prosthetic rehabilitation of a patient with a totally edentulous maxilla using a fixed prosthesis supported by six implants, but modified by the inclusion of a removable gingival veneer retained with attachments. This alternative provides a rehabilitation model as functional and comfortable as the fixed prosthesis, enhancing facial aesthetics (reestablishing lip support) and phonetics and facilitating patient access for proper periimplant hygiene and prosthesis cleaning. We concluded that implant-supported fixed maxillary restorations, modified by the inclusion of a removable gingival veneer, come as a great alternative in cases of severe maxillary alveolar ridge atrophy...

Sindrome de sjogren: relato de caso / Spogrens syndrome: case report

Objetivos: Apresentar um caso clínico enfantizando a abordagem terapêutica realizada pelo cirurgião dentista com a finalidade de melhorar a qualidade de vida dos pacientes acometidos pela Sindome Sjogren. Descrição do caso: Paciente feminina com síndrome de Sjogren encaminhada para reabilitação protética apresentava ressecamento da face, olhos, lábios e toda mucosa bucal. Queixava-se de dificuldade para falar, mastigar e engolir. Foi realizada a adequação bucal e foram dadas instruções relacionadas à dieta alimentar. Para a reabilitação do espaço edentado tipo classe III de Kennedy, optou-se por uma prótese parcial removível convencional com redentores extracoronários. Foi prescrito flúor em forma de bochecho diário e gel oral umidificador, duas vezes ao dia. Foi delineado um programa de acompanhamento e manutenção para a paciente pudesse manter, com sucesso, a saúde bucal estabelecida. Conclusões: A síndrome de sjogren compreende anormalidades em diversos setores do organismo, incluindo a saliva, que desempenha importante papel na fisiologia e biologia do ser humano. Portanto, a interdisplinaridade, com envolvimento do cirurgião dentista, é exterma importância para o sucesso terapêutico desta doença.
