Mechanical influence of thread pitch on orthodontic mini-implant stability

Brazilian Oral Research, 2015
The aim of this study was to evaluate the effect of pitch distance on the primary stability (PS) of orthodontic mini-implants (MIs) in artificial bone. Twenty experimental MIs were allocated to two groups, according to their geometric design: G1(30oX 0.6

Distal Upper Molar Force Distribution With Clear Aligners Using Different Anterior Teeth Anchorage Setups: A Finite Element Study. [PDF]

Orthod Craniofac Res
ABSTRACT Objective The notion that clear aligners alone can distalize upper molars without affecting anterior teeth is inaccurate. Although strategies such as Class II elastics, tooth‐movement sequencing, and attachment variations have been investigated to mitigate unwanted side effects, temporary anchorage devices have demonstrated potential for ...

Comparative efficacy of novel bioactive glass versus sodium fluoride toothpaste for dentin hypersensitivity

Journal of Periodontology, EarlyView.
Abstract Background This first‐in‐human clinical study aimed to evaluate the safety and efficacy of a bioglass incorporated in a toothpaste, in reducing dentin hypersensitivity (DH) compared to a sodium fluoride (NaF) toothpaste over a 2‐week period. Methods A double‐blind, randomized, parallel‐arm, proof‐of‐concept clinical trial was conducted with 46

Cyotoxicity of Etidronate as an Endodontic Chelator Against Periodontal Ligament Fibroblast

Australian Endodontic Journal, EarlyView.
ABSTRACT Etidronic acid (HEBP) causes fewer alterations in dentine and can be used mixed with sodium hypochlorite during root canal preparation. This study investigated the cytotoxicity effects of the HEDP and EDTA on human periodontal ligament fibroblast cells. Primary culture was established from human periodontal ligament tissue of one donor and was
