13. Indicators of the risk mechanics for Class-I and Class-II amalgam and composite resin restorations
AIM: To determine indicators of prognosis for mechanical risks of amalgam and composite resin restorations in permanent teeth. METHODS: Thirty-nine adult patients with direct clinical, photographic, radiographic and model examinations. A total of 256 restorations were classified as "not satisfactory," with Bravo or Charlie values according to the modif

14. Evaluation of the adaptation of zirconia-based fixed partial dentures using micro-CT technology
The objective of the study was to measure the marginal and internal fit of zirconia-based all-ceramic three-unit fixed partial dentures (FPDs) (Y-TZP - LAVA, 3M-ESPE), using a novel methodology based on micro-computed tomography (micro-CT) technology. Stainless steel models of prepared abutments were fabricated to design FPDs. Ten frameworks were produced wi

15. Microleakage in combined amalgam/composite resin restorations in MOD cavities
AIM: To compare marginal seal at tooth-material and material-material interfaces in the proximal box in combined amalgam/composite resin restorations. METHODS: Mesio-occlusal-distal (MOD) cavities were prepared in 35 premolars and permanent molars with carbide bur. The distal proximal box was restored with amalgam (Permite, SDI) until reaching the height of

16. Marginal adaptation of class V composite restorations submitted to thermal and mechanical cycling
Objective This study evaluated the effect of the margin location and an adhesive system on the marginal adaptation of composite restorations. Material and Methods Class V cavities were prepared in bovine teeth with the gingival margin on the dentin and the incisal margin on the enamel. The cavities were restored with a micro-hybrid composite resin using an

17. Avaliação de próteses fixas sobre implantes com diferentes níveis de ajuste pilar/prótese: efeito da ciclagem termomecânica sobre diferentes parafusos protéticos e análise fotoelástica da transmissão de tensões / Evaluation of fixed implant-supported prostheses with different levels of abutment/prosthesis fit: the effect of thermomechanical cycling on different abutment screws and photoelastic analysis of stress transmission
O objetivo deste estudo foi verificar os efeitos da ciclagem termomecânica sobre parafusos protéticos, convencionais de titânio e com cobertura de carbono, usados para fixação de próteses parciais fixas com desajuste de 150µm entre pilar e prótese, utilizando próteses sem desajuste como controle. Após ciclagem termomecânica das próteses, foram ve

18. Stress distribution and screw detorque analysis : influence of misfit and alloy types in cast implant retained frameworks / Avaliação das tensões e do destorque de parafusos : influência do desajuste marginal e dos tipos de metais em infraestruturas protéticas retidas por implantes
O objetivo neste estudo foi avaliar a distribuição das tensões geradas aos implantes modificados, por meio de análise extensométrica e força de destorque dos parafusos de retenção protética, de acordo com o tipo de metal da infraestrutura (Titânio comercialmente puro - Ti c.p ou Cobalto-Cromo - Co-Cr) e presença ou ausência de desajuste vertical

19. A new portable vibrator for plaster pouring: effect on the marginal fit at cylinder-abutment
OBJECTIVE: The aim of this study was to test a new portable vibrator for plaster pouring (developed for this purpose), comparing the effect of its use on the accuracy of working cast of implant-supported restorations to the conventional vibrator. MATERIAL AND METHODS: From a master cast with 2 implants, 30 transfer moldings were made randomly and divided int

20. Impact of adhesive and photoactivation method on sealant integrity and polymer network formation
We evaluated the influence of photoactivation method and hydrophobic resin (HR) application on the marginal and internal adaptation, hardness (KHN), and crosslink density (CLD) of a resin-based fissure sealant. Model fissures were created in bovine enamel fragments (n = 10) and sealed using one of the following protocols: no adhesive system + photoactivation

21. 56-month clinical performance of Class I and II resin composite restorations
OBJECTIVE: This study evaluated the 56-month clinical performance of Class I and II resin composite restorations. Filtek P60 was compared with Filtek Z250, which are both indicated for posterior restorations but differ in terms of handling characteristics. The null hypothesis tested was that there is no difference in the clinical performance of the two resin

22. Two-year clinical evaluation of three adhesive systems in non-carious cervical lesions
OBJECTIVES: Adhesive systems are continuously being introduced to Dentistry, unfortunately often without sufficient clinical validation. The aim of this study was to evaluate the clinical performance of cervical restorations done with three different adhesive systems. MATERIAL AND METHODS: 158 non-carious cervical lesions of 23 patients were restored with a

23. A randomized double-blind clinical trial of posterior composite restorations with or without bevel: 1-year follow-up
OBJECTIVE: This randomized double-blind clinical trial compared the performance of posterior composite restorations with or without bevel, after 1-year follow-up. MATERIAL AND METHODS: Thirteen volunteers requiring at least two posterior composite restorations were selected. Twenty-nine cavities were performed, comprising 14 without bevel (butt joint) and 15

24. Interfacial adaptation of an epoxy-resin sealer and a self-etch sealer to root canal dentin using the System B or the single cone technique
O objetivo deste estudo laboratorial foi avaliar comparativamente a adaptação na interface obturação/dentina em canais mesiais de molares inferiores obturados com System B, tanto com guta percha/ThermaSeal Plus como com Resilon/Real Seal SE. Os canais mesiais de 60 molares inferiores foram modelados utilizando o sistema rotatório K3, realizando o batent
