Industrial Noise and Tooth Wear - Experimental Study
UNLABELLED Tooth wear is a complex multifactorial process that involves the loss of hard dental tissue. Parafunctional habits have been mentioned as a self-destructive process caused by stress, which results in hyperactivity of masticatory muscles. Stress manifests itself through teeth grinding, leading to progressive teeth wear. The effects of continuous exposure to industrial noise, a "stress...
متن کاملTooth mobility and periodontal therapy.
Data collected as part of an 8-year longitudinal study on periodontal therapy involving 82 patients and 1974 teeth were analyzed to determine if tooth mobility influenced the result of treatment. For each patient, pocket depth, attachment level and tooth mobility were scored clinically at the initial appointment, and once a year for 8 years following periodontal therapy. The treatment consisted...
متن کاملTooth Growth in Experimental Scurvy
1. The incisor teeth of guinea pigs have a constant rate of growth in health. 2. Deprivation of Vitamin C causes the teeth to cease growing. Readministration of the vitamin restores the growth. 3. Administration of small amounts of antiscorbutic substance results in rates of growth roughly proportional to dosage. 4. Under standard experimental conditions used in the testing of foodstuffs for an...
متن کاملDevelopment of a device to simulate tooth mobility.
OBJECTIVES The testing of new materials under simulation of oral conditions is essential in medicine. For simulation of fracture strength different simulation devices are used for test set-up. The results of these in vitro tests differ because there is no standardization of tooth mobility in simulation devices. The aim of this study is to develop a simulation device that depicts the tooth mobil...
متن کاملEffect of Intra-Canal Direct Current Electric Stimulation on Orthodontic Tooth Movement: An Experimental Study in Canines
Objectives: The purpose of this study was to evaluate whether intra-canal application of controlled direct electric current (DEC) could accelerate the amount of orthodontic tooth movement (OTM) in young adult mixed breed dogs. Methods: Fourth premolars of both jaws of five young adult mixed breed dogs were divided into two groups of control and experimental groups. Orthodontic force...
