Objective: to assess the characteristics associated withtemporomandibular disorders (TMD) and their impacton oral health-related quality of life (OHRQoL) of institutionalizedelderly people. Subjects and method: itwas a cross-sectional study performed in 30 private institutionsfor the elderly. The data collected included theTMD questionnaire and clinical evaluation assessed bythe Research Diagnostic Criteria/TemporomandibularDisorders (RDC/TMD), as well as the OHIP-49 questionnairefor OHRQoL. Results: twenty-four institutionsaccepted to participate in the study (n = 375 with 133fit for answering both questionnaires). Considering thecharacteristics, tinnitus was the most frequent symptomreported, while 98.5% of the research participants didnot present myofascial pain. Disc displacement wasobserved in 26.3%, while 93% of individuals did notpresent chronic pain. Severe depression was found in23.3% of the elderly with 24.1% presenting moderatelevels of non-specific physical symptoms, includingpain. Poisson regression analysis showed that the characteristicsreported were associated with a negativeimpact on OHRQoL. Conclusion: the domain-specificanalysis showed that all domains were affected negativelyby TMD characteristics and higher levels of depressionare associated with a negative impact on OHRQoL. (AU)

Therapies for bruxism: a systematic review and network meta-analysis (protocol).

BACKGROUND: Bruxism is a sleep disorder characterized by grinding and clenching of the teeth that may be related to irreversible tooth injuries. It is a prevalent condition occurring in up to 31% of adults. However, there is no definitive answer as to which of the many currently available treatments (including drug therapy, intramuscular injections, physiotherapy, biofeedback, kinesiotherapy, use of intraoral devices, or psychological therapy) is the best for the clinical management of the different manifestations of bruxism. The aim of this systematic review and network meta-analysis is to answer the following question: what is the best treatment for adult bruxists? METHODS/DESIGN: Comprehensive searches of the Cochrane Library, MEDLINE (via PubMed), Scopus, and LILACS will be completed using the following keywords: bruxism and therapies and related entry terms. Studies will be included, according to the eligibility criteria (Controlled Clinical Trials and Randomized Clinical Trials, considering specific outcome measures for bruxism). The reference lists of included studies will be hand searched. Relevant data will be extracted from included studies using a specially designed data extraction sheet. Risk of bias of the included studies will be assessed, and the overall strength of the evidence will be summarized (i.e., GRADE). A random effects model will be used for all pairwise meta-analyses (with a 95% confidence interval). A Bayesian network meta-analysis will explore the relative benefits between the various treatments. The review will be reported using the Preferred Reporting Items for Systematic Reviews incorporating Network Meta-Analyses (PRISMA-NMA) statement. DISCUSSION: This systematic review aims at identifying and evaluating therapies to treat bruxism. This systematic review may lead to several recommendations, for both patients and researchers, as which is the best therapy for a specific patient case and how future studies need to be designed, considering what is available now and what is the reality of the patient.

Rehabilitation of severely worn teeth: A systematic review.

OBJECTIVES: The aim of this systematic review was to evaluate the treatment performance/longevity of dental materials/techniques indicated to restore teeth with severe wear. MATERIALS AND METHODS: A systematic literature search was conducted to select retrospective studies (cohort and case series) and prospective studies that evaluated or compared techniques/materials to restore teeth with severe wear. A search was conducted in Medline (via Pubmed - June 2015) with no limits for publication year or language to identify clinical studies. Two reviewers independently selected studies, extracted data and assessed the risk of bias of randomized controlled trials included. The annual failure rate (AFR%) of restorations was calculated for each study. RESULTS: A total of 511 articles were found and 23 studies were eligible for full-text analysis; hand search included 7 more papers. From the 30 studies, 12 were eligible for the review. Most of these studies presented good performance of the restorations in teeth with severe wear. AFR ranged from 0.4% (microhybrid) to 26.3% (microfilled) for direct resin composite, 0% to 14.9% for indirect resin composite and 2.7% for porcelain veneers. CONCLUSION: There is no strong evidence to suggest that any material is better than another. Direct or indirect materials may be feasible options to restore severely worn teeth.

Reabilitação oral do desgaste dentário severo com resina composta

Introdução: a utilização de resinas compostas diretas tem sido ampliada devido a melhoras tanto nas propriedades adesivas quanto nas propriedades físicas dos materiais. Aprimoramentos técnicos também fizeram com que os compósitos passassem a ser utilizados inclusive na reabilitação de casos de extensas perdas de tecidos dentários, mostrando um bom desempenho clínico em estudos longitudinais. As reabilitações das lesões não cariosas tendem a aumentar na clínica odontológica, em função de uma maior longevidade de indivíduos que mantiveram a sua dentição natural, especialmente naqueles casos em que um desgaste dentário severo (DDS) tenha ocorrido em função de atrição, erosão, abrasão ou por combinações dessas. Objetivos: apresentar um apanhado das técnicas disponíveis para o uso de resinas compostas diretas (RCDs) aplicáveis na reabilitação de pacientes que tenham DDS, bem como descrever essas técnicas, discutindo suas vantagens e desvantagens. Revisão de literatura: uma busca na literatura previamente realizada apontou que as RCDs têm indicação para tratamentos conservadores em casos com DDS. Considerações finais: as técnicas diretas estão indicadas como uma alternativa para esse tipo de reabilitação porque apresentam longevidade aceitável, com um bom nível de satisfação por parte dos pacientes e baixo custo biológico e financeiro.

Should occlusal splints be a routine prescription for diagnosed bruxers undergoing implant therapy?

Despite the documented excellent clinical performance of dental implants, concerns linger regarding the best way to protect the restored dentition in patients with bruxism. This is because of the risk of occlusal overload that is reported to cause biological and biomechanical failures in the implant-prosthesis system. To better distribute occlusal loads to the rigid components of the prosthesis and to the interface between bone and implant during parafunctional movements, several dentists prescribe acrylic resin occlusal splints for nocturnal use by patients considered at risk. However, it is unclear whether this recommendation is based on scientific evidence or expert clinical opinion. This report reflects our effort to employ the systematic review protocol to assess whether there is scientific evidence to recommend an occlusal splint in bruxers after implant therapy.

Acid foods and soft drinks dental erosive potential: warning messages or not? / Potencial erosivo dental de alimentos acidos y bebidas no alcohólicas: ¿existen mensajes de advertencia?

This Communication aims to present the issue of dental erosion in another point of view. Considering the increasing rate of incidence of this dental injury among children and adults, the narrative raises the question about the danger of indiscriminate intake of certain acidic foods and beverages which are scientifically proven as one of the causes of dental erosion, as well as the complete neglect of information by the food industry about these products. The authors present some points that still remain in doubt in this topic and some approaches, which should be taken to alert the population about the relation between acidity of food and dental erosion

El objetivo del presente estudio es abordar el tema de la erosión dental desde otro punto de vista. Al tener en cuenta la creciente tasa de incidencia de esta lesión dental en niños y adultos, el trabajo plantea la pregunta sobre el peligro de la ingesta indiscriminada de ciertos alimentos ácidos y bebidas que han sido identificados científicamente como una de las causas de la erosión dental, como asimismo, una completa falta de información por parte la industria alimentaria sobre estos productos. Se presentan algunos puntos que aún quedan en duda referente a este tema y algunos enfoques que se deben tomar para alertar a lapoblación acerca de la relación entre la acidez de los alimentos y la erosión dental

Resilient Attachments as an Alternative to Conventional Cast Clasp Removable Partial Denture: 3-Year Follow-up.

The present clinical report describes the prosthodontic management for a patient with uncontrolled bleeding and diabetes mellitus treated with a maxillary complete denture and a mandibular partial fixed dental prosthesis designed to interface with a removable cast framework partial denture retained by 2 ERA attachments. This approach was undertaken to improve both retention and stability of the distal extension Kennedy Class I removable partial denture. The rehabilitation provided better anterior esthetics than if treated with a conventional clasp retained removable partial denture, by employing a simple, practical design and offering a significant biomechanical advantages, restoring both oral health and function. Thus, this treatment modality, involving an ERA system and transfixation in fixed crowns, is an effective treatment and can be indicated as a clinical alternative for edentulous and partially edentulous patients with systemic disorders or for patients in economic situations that might preclude implant-based rehabilitation.

Can we close large prosthetic space with orthodontics?

For years, the treatment for the replacement of a missing tooth was a fixed dental prosthesis. Currently, implants are indicated to replace missing teeth due to high clinical success and with the advantage of not performing preparations in the adjacent tooth. Another option for space closure is the use of orthodontics associated to miniscrews for anchorage allowing better control of the orthodontic biomechanics and especially making possible closure of larger prosthetic spaces. Thus, this article describes two cases with indications and discussion of the advantages and disadvantages of using orthodontics for prosthetic spaces closure. The cases herein presented show that it is possible to close an space when there are available teeth in the adjacent area. It can be concluded that when a malocclusion is present there will be a strong trend to indicate space closure by orthodontic movement as it preserves natural teeth and seems a more physiological approach.
