Biomechanics of internal connection in mandibular implant-supported prosthesis under effect of loadings and number of implants: A 3D finite element analysis.

Introduction: The success of bone-implant prostheses depends on several factors, among them an adequate distribution and passive adaptation of occlusal loading.

Objective: this study evaluated the stress distribution in mandibular implant-supported prosthesis with internal connection morse taper interface, under effect of number of implants (4 or 5) and loadings (bilateral 100 N, bilateral 300 N).

Materials And Methods: the virtual models were subjected to analysis by 3D finite element method, across four experimental conditions.

Simplified ethanol wet-bonding technique: an alternative strategy for resin-dentin bonding in root canals.

The objective of this study was to evaluate the effect of the simplified ethanol wet-bonding technique on luting of posts to intraradicular dentin. The effect was assessed by push-out bond strength testing and confocal laser scanning microscopic analysis. Thirty endodontically treated roots were distributed into 3 groups (n = 10): water wet-bonding; stepwise ethanol wet-bonding; and simplified ethanol wet-bonding.

Comparison of Bite Force with Locking Plates versus Non-Locking Plates in the Treatment of Mandibular Fractures: A Meta-Analysis.

 Mandibular fractures represent a high percentage of all facial fractures, and the bite force is a fundamental parameter to measure the actual mandibular function and, subsequently, the masticatory efficiency and quality of life.  The purpose of the present systematic review was to verify if there is any difference in the bite forces of patients with mandibular fractures fixed by locking or non-locking plates, testing the null hypothesis of no difference in this parameter.  A systematic review of the literature was conducted using four databases (PubMed, Virtual Health Library, Web of Science and Science Direct) without restrictions as to publication date or language.

Relationship between sjögren syndrome and periodontal status: A systematic review.

Objective: This study aimed to examine whether Sjögren syndrome (SS) is related to periodontal status.

Study Design: A systematic review was performed on the basis of PRISMA (PROSPERO: CRD42017055202). A search was performed in the PubMed/MEDLINE, LILACS, Web of Science, and Science Direct databases.

Effects of propolis on lingual mucosa response of hamsters submitted to experimental carcinogenesis.

Objective: To assess the tissue reaction of the lingual mucosa in hamsters submitted to daily, alternating, topical applications of 9,10-dimethyl-1,2-benzanthracene (DMBA) and a commercial brand of an ethanol propolis extract (EPE).

Methods: A total of 60 hamsters were divided into three groups with two experimental periods (13 and 20 weeks). The lateral edge of the tongue was submitted to daily, alternating, topical applications of 0.

Effect of propolis on mast cells in wound healing.

Wound healing is divided into three phases: inflammatory, proliferative and remodeling. Mast cells participate in all these phases. The aim of the present study was to determine the effects of propolis on the population of mast cells in oral surgical wounds in comparison to the results obtained with dexamethasone.
