In randomised trials, internal validity is defined as ‘‘the extent to which the design and conduct of a study are likely to have prevented bias’’ [1,2]. In conducting such trials, trialists try to prevent selection bias through randomisation and allocation concealment (defined as ‘‘the process used to ensure that the person deciding to enter a participant into a randomised controlled trial does...

STATEMENT OF PROBLEM Interest in posterior partial coverage restorations has increased because these restorations provide a more conservative treatment option than traditional cohesively based restorations; however, material selection has been a controversial topic in the current literature. PURPOSE To evaluate the fracture resistance of posterior partial coverage restorations restored with d...

Objective: The purpose of the current study was to evaluate clinical, radiographic and mounted study cast assessment of the abutment on designing of fixed partial denture. Patient & method: The present study was limited to patients who treated by postgraduate students of Conservative Department, School of Dentistry/Faculty of Medical Sciences between January 2014 to February 2015. A total numbe...

Dental traits have long been assumed to be under selection in mammals, based on the macroevolutionary correlation between dental morphology and feeding behaviour. However, natural selection acting on dental morphology has rarely, if ever, been documented in wild populations. We investigated the possibility of microevolutionary selection on dental traits by measuring molar breadth in a sample of...

Finite element analysis (FEA) is a computational technique of growing popularity in the field of comparative biomechanics, and is an easily accessible platform for form-function analyses of biological structures. However, its rapid evolution in recent years from a novel approach to common practice demands some scrutiny in regards to the validity of results and the appropriateness of assumptions...

STATEMENT OF PROBLEM The distal offset placement of a single implant to replace a single tooth would overcome the shortcomings of the placement of a single wide implant in the posterior region. However, long-term evaluation is still-lacking. PURPOSE The purpose of this study was to evaluate the long-term outcomes of patients treated with a single tooth restoration supported by a distal-offset...

BACKGROUND Caries, enamel hypoplasia, molar incisor hipomineralization, amylogenesis imperfecta, dentine dysplasia, hypophosphatasia and other dental disorders lead to tooth mineralization disturbances and structural abnormalities, decreasing masticatory organ functions. Dental disorders in sheep can lead to premature slaughter before they have attained final stage of their reproductive life an...

Tooth morphometry is known to be influenced by cultural, environmental and racial factors. Tooth size standards can be used in age and sex determination. One hundred models (50 males & 50 females) of normal occlusion were evaluated and significant correlations (p<0.001) were found to exist between the combined maxillary incisor widths and the maxillary intermolar and interpremolar arch widths. ...
