Spontaneous corrections in orthodontic anomalies can sometimes be expected, when all hindrances are eliminated, and the relevant teeth are given every freedom. Although there seems to be no exact explanation for the corrections some speculations are presented. Advantages and disadvantages are discussed.
Line drawings of facial profiles and color photographs of dentitions were evaluated subjectively by 1,150 parents, 72 general practictioners of dentistry, and 54 orthodontists with regard to the normality and abnormality in dentofacial morphology and the need for orthodontic treatment. A significant difference was found between the evaluations of the parents and the professional groups in ten of the 11 facial profiles and in seven of the 11 photographs of dentitions. In general, the parents considered more of the examples acceptable and not requiring orthodontic treatment than did the professional groups. The dentists and orthodontists deviated significantly in their ratings onjy in their judgement of "ugly duckling" example (picture 22, higher abnormal rating by the dentists) and the profile example 10 (higher abnormal rating by orthodontists). number of orthondontists may have associated the conditions in picture 10 with a Class II, Division 2 malocclusion and, as such, scored it abnormal.
