Island populations tend, by their nature, to be more endogamous, so dental traits that appear to be hereditary, such as third molar agenesis, could easily exhibit relatively high frequencies [69].
In all, 10 paraffined and five frozen specimens of healthy oral mucosa were obtained from patients who had undergone routine oral surgical procedures (such as impacted third molars, metaprotesic reactive epithelial hyperplasia, etc).
Conclusions: This study was designed to provide baseline health-related quality of life information with which to compare other surgical procedures frequently needed in orthodontic treatment, such as removal of third molars and exposure of impacted teeth.
The authors explained the results by stating that in Wales, a protocol was developed which provides guidelines to decide whether or not to extract third molars, whereas such protocol is not widely accepted in Sweden.
Only 55% correctly recognized the risks for ischaemic heart disease and just 6.7%, the risk of deep-vein-thrombosis. Traditional experience can also be a poor judge of the efficacy of treatments such as the widespread prophylactic removal of pathology-free impacted third molars to prevent cysts and tumours, resorption of second molars, caries and periodontal problems.
If a study also included the investigation of the maturity of any of the incisors, or of the first and third molars, they were not considered here because these teeth are usually fully developed in the pre-pubertal growth phase or are very late, such as for the third molars.
Retained asymptomatic third molars and risk for second molar pathology.
Twelve third molars were selected.
Third molars were excluded from our assessment.
Agenesis of third molars was excluded [117].
