AIM This study evaluates the relationship between occlusal interferences and premature contacts and bruxism by determining the relationship between unassisted and assisted nonworking interferences. MATERIALS AND METHODS In this study, 60 subjects (14 males and 46 females) that consisted of 30 bruxers (7 males, 23 females) and 30 nonbruxers (7 males, 23 females) were selected after completion ...

Numerous factors help to conserve the dentition of elderly patients, such as healthy food habits, a strong physical constitution, and a good quality of life. The aim of this study was to define a model that takes into account the integration of both the structural and functional aspects of a healthy dentition. Twenty-three patients aged at least 75 years were recruited. The patients were requir...

AIM This was to investigate the incidence of dental caries on the occlusal surface of the first permanent molars of schoolchildren, and also the associated sociodemographic, behavioural and biological risk factors. MATERIALS AND METHODS A three-year longitudinal study on dental caries of the occlusal surface of the first permanent molars was carried out in 224 children between 9 and 11 years ...

BACKGROUND AND AIMS Bruxism is defined as a habitual nonfunctional forceful contact between occlusal tooth surfaces. In younger children bruxism may be a consequence of the masticatory neuromuscular system immaturity. The aim of this study was to assess the prevalence of bruxism and investigate the relationship between occlusal factors and bruxism among preschool children. MATERIALS AND METHO...

4Reader, Department of Periodontics, JCD Dental College Sirsa, Haryana, India. ABSTRACT The goal of any prosthetic procedure must include the establishment of a functional occlusion. It is known that natural teeth have periodontal ligament receptors that protect the teeth from excessive occlusal forces, which can cause trauma to supporting tissues and bone. Although many factors are involved in...

We used functional near-infrared spectroscopy to measure prefrontal brain activity accompanying the physical sensation of oral discomfort that arose when healthy young-adult volunteers performed a grinding motion with mild occlusal elevation (96 μm). We simultaneously evaluated various forms of occlusal discomfort using the visual analogue scale (VAS) and hemodynamic responses to identify the s...

The aim of this study was to determine the correlation between the static and dynamic occlusal factors in patients with anterior disk displacement (DD) and to compare it with occlusion in asymptomatic individuals. The study included a group of 40 patients with DD (median age 35.5) and a control group of 25 students of dental medicine (median age 23.4). In all subjects, the position, i.e. DD was...

Sufficient Cause vs. Causal Factor Clark’s (1991) comment that “a high percentage of patients who have a naturally occurring ‘occlusal abnormality’ do not exhibit TM disorder” discloses that a distinction between the concepts “sufficient cause” and “causal factor” has not been made. This criticism applies also to the review by DeBoever et al. (2000). The conclusion should have read: “The litera...
