Introduction: Unilateral or bilateral distal-extension removable partial dentures present complex biomechanics. The movements in different directions, associated with the alveolar ridge shape and soft tissue resilience can lead to damaging forces on the supporting structures. The association between implants / removable partial denture aims to provide better mechanical and biological properties to the stomatognathic system. Objective: The aim of this paper was to review the articles about the effect of implant support on distal extension removable partial dentures. Literature review and conclusion: Studies have shown that this combination provides greater support, retention and stability to the prosthesis, thus limiting their approach movement toward supporting tissues and providing functional and psychological comfort to patients.

Objective: The aim of this study was to evaluate the pH of calcium hydroxide (CalenTM) when associated or not with chlorhexidine 0.4%, and when associated with chlorhexidine with the addition of 20% or 10% of alphatocopherol (AchéTM), assessed in several periods of time. Methods: Fourty dentine tubes 20 mm, properly standardized, were made from bovine anterior teeth roots. Following, a perforation was achieved in the roots distal face at 7 mm from the cervical radicular line by using a #1/2 carbide bur. After complete root sealing is made, except in the perforation local, the radicular canals were filled with one of the following associations: Group I – Calen®; Group II – Calen™ with chlorehxidine at 0.4%; Group III – Calen™ with chlorhexidine at 0.4% with the addition of 20% (weight) of alhatocopherol compound and Group IV – Calen™ with chlorhexidine at 0.4% with the addition of 10% (weight) alphatocopherol. After cervical sealing is accomplished, the roots were immersed in water MiliQ and the pH, assessed in 24h, 7, 14, 21, 28 and 45 days. Results and Conclusion: In all periods tested, the pH of the calcium hydroxide (Calen™) was similar to the pH of the calcium hydroxide (Calen™) associated with chlorhexidine 0.4% and 10% alphatocopherol (p > 0.05). The association of 20% alphatocopherol obtained the pH lower than the association with 10% (p < 0.05). The pH of the association with chlorhexidine was similar to the pure calcium hydrocide (Calen™) after the 14th day (p > 0.05) only. Therefore, on the 45th day, this difference was significant again (p < 0.05).

Esse artigo tem como objetivo demonstrar o restabelecimento estético do sorriso obtido por meio da associação de facetas diretas e fibra de reforço. As fibras de reforço são utilizadas como alternativa para substituição de elementos dentários perdidos e possuem indicações precisas, sendo empregadas em diversas especialidades da Odontologia, devido à sua capacidade de aumentar a resistência à tração dos compósitos, o que aumenta a resistência à compressão das fibras. Para o completo restabelecimento do sorriso, muitas vezes é necessário reanatomizar os dentes adjacentes, considerando as condições em que esses se apresentam. Sendo assim, o profissional deve ter conhecimento para aplicação correta da técnica e restabelecimento da estética ao paciente.

Periodontitis is a chronic inflammatory disease that results in the destruction of teeth and their supporting tissues with subsequent tooth loss. The replacement of missing teeth for implant-supported restorations has proven to be a highly predictable treatment method with good long-term prognosis. However, some consequences of tooth loss prevents dental implant placement in an ideal position, where regenerative procedures are necessary for this type of rehabilitation. Less invasive procedures such as conventional prosthesis emerge as a therapeutic option in cases where there is enough bone structure for implants and patient´s non-acceptance for invasive procedures. Thus, this paper aims to present the resolution of rehabilitation through a noninvasive and multidisciplinary treatment. One female patient referred to the clinic presented maladaptive bilateral mandibular fixed prostheses, endodontic lesions, gingival recession, and root sensitivity. For proper resolution of this case, an association among osseointegrated implants, fixed partial prosthesis, tooth extraction, and aesthetic periodontal procedures with the use of subepithelial connective tissue graft was proposed. After two years, the patient shows excellent aesthetics and chewing. Within the limits of this scenario, this paper discusses the various factors that may affect the choice of a particular treatment modality for the rehabilitation of edentulous single spaces.

Com o avanço das técnicas e materiais restauradores, o cirurgião-dentista tornou-se capaz de solucionar problemas estéticos de forma conservadora. Esse relato de caso descreve a associação das técnicas de microabrasão e fechamento de diastemas com resinas compostas diretas. A paciente do sexo feminino, 16 anos de idade, foi encaminhada pelo ortodontista à clínica de Dentística Restauradora para o fechamento de diastema. Após anamnese e exame clínico detalhado, constatou-se, também, a presença de manchas brancas de fluorose na face vestibular dos dentes anterossuperiores, sendo também proposto o procedimento de microabrasão. Por meio de modelos de estudo da paciente, foi realizado o enceramento diagnóstico, de forma a simular o fechamento dos diastemas. O modelo encerado foi moldado com silicona de condensação para servir como guia de orientação durante os procedimentos restauradores. O tratamento resultou na elevação da autoestima da paciente, pela obtenção de um sorriso mais harmonioso por meio da associação de técnicas estéticas conservadoras.

A total of 350 commercial Bovans White laying hens were used to evaluate the association of carbohydrases and phytase in enriched diets and its effects on performance and egg quality of laying hens. The experiment used a randomized design with five treatments and seven replicates. The treatments were: 1. Positive control without added enzymes and without nutrient enrichment, 2. Negative control (NC) 1 with 1.5% and 6% AME (kcal/kg) enrichment for corn and soybean meal respectively, 2% crude protein (CP) enrichment, and digestible limiting digestible amino acids plus the full matrix for the phytase enzyme; 3. NC 2 with 1.5% and 6% AME (kcal/kg) enrichment, respectively, for corn and soybean meal and 2% crude protein (CP) enrichment, and digestible limiting amino acids plus the sparse matrix for the phytase enzyme, 4. NC 1 supplemented with 100 g ton(-1) carbohydrase and 30g ton(-1) phytase, 5. NC 2 supplemented with 100 g ton(-1) carbohydrase and 30g ton(-1) phytase. According to the results, the positive control treatments, NC1 and NC2, with or without enzyme supplementation, showed guaranteed performance for feed intake, egg yield, weight, egg loss and shell quality.
