Following experience with several clinical trials, the semantic, logical, and statistical properties of the Clinical Global Impressions Scale (CGI-ECDEU, 1976; CIPS, 1986) were investigated. It was concluded that the CGI in its present version (a) may induce inconsistent rating behavior, (b) contains redundant information, (c) consists of items which exhibit ...

It can be as important to quantify lack of tenderness, as tenderness. Palpation detects tenderness only; dolorimeters with a limited scale restrict ability to assess variations in thresholds at clinically nontender sites. Such variations must be measured if we are to evaluate generally acting factors affecting tenderness. We measured thresholds ...

Interincisor angulation is commonly held to be a critical factor in determining overbite depth, where there is incisor contact. In this study significant correlations between these variables were found in Class II, division 2 malocclusions although interincisor angle explained less than a third of the variance in overbite depth. It ...

According to several studies on human populations, the mandible deviates on opening significantly more often to the left than to the right. An association between the asymmetry of opening and handedness has been suggested. The present study of 143 left-handed Finnish conscripts showed no significant difference from the asymmetry reported ...
