Influence of low insertion torque values on survival rate of immediately loaded dental implants: A systematic review and meta-analysis.

Aim: The aim was to systematically evaluate the effect of low insertion torque values on the survival rate of immediately loaded dental implants.

Materials And Methods: The protocol was registered with PROSPERO (ID CRD42020189499). An electronic search was performed in PubMed, Embase, Web of Science, and Cochrane Central Register of Controlled Trials until June 2022 in English and Spanish.

Periodontal response to a tricalcium silicate material or resin composite placed in close contact to the supracrestal tissue attachment: a histomorphometric comparative study.

Objective: Subgingival dental restorations and periodontal health have been studied for many years; however, there is a low histological evidence on the behavior of new materials in the supracrestal tissue attachment. The aim of this study is to analyze the periodontal response when a tricalcium silicate material (TSM) or composite margin restorations is placed to 0.5 mm and 1.

Long-term clinical evaluation of Dyract compomer in the restoration of non-caries cervical lesions: A 20-year retrospective study.

Objective: The restoration of non-caries cervical lesions has long been a challenge. Until recently, compomers were the restorative materials of choice. The aim of this in-vivo study was to evaluate the long-term clinical performance of Dyract restorations in non-caries cervical lesions.

Mechanical properties related to the microstructure of seven different fiber reinforced composite posts.

Purpose: The aim of this study was to evaluate the mechanical properties (bending strength and hardness) of seven different fiber reinforced composite posts, in relation to their microstructural characteristics.

Materials And Methods: Two hundred eighty posts were divided into seven groups of 40, one group for each type of post analyzed. Within each group, 15 posts were subjected to three-point bending strength test, 15 to a microhardess meter for the Knoop hardness, and 10 to Scanning Electron Microscope in order to determine the diameter of the fibers and the percentage of fibers embedded in the matrix.

Retrospective evaluation of posterior composite resin sandwich restorations with Herculite XRV: 18-year findings.

Objective: The aim of this retrospective study was to evaluate the long-term clinical outcomes of posterior composite resin sandwich restorations, and secondarily to assess the influence of potential factors on survival and causes of failure.

Method And Materials: Two hundred and four posterior Herculite XRV restorations due to primary caries performed between 1991 and 1997 were included. The restorations were assessed after 18 years, by two calibrated examiners, according to USPHS criteria.
