Extraction of third molars in cases of anticipated crowding in the lower jaw

The Role of Mandibular Third Molars on Lower Anterior Teeth Crowding and Relapse after Orthodontic Treatment : A Systematic Review

“…The presence of the third molars was not correlated with more severe anterior tooth crowding in most of the studies [3, 5, 6, 12, 14, 17-19]; however, some of them described 4 The Scientific World Journal [2,13,15,16]. Sheneman found more dental stability in orthodontically treated subjects with congenitally missing third molars when compared with subjects with either unerupted or erupted third molars at five-year follow-up [13].…”

“…Seven articles that were first selected by the title for further evaluation could not be found, mainly because the year of publication was very old. Thus, a total number of 12 controlled studies were included in the review (Table 1) [2,3,5,6,[12][13][14][15][16][17][18][19]. The quality assessment of the selected studies revealed a high risk of bias in most of the articles, either because the relative items assessed were inadequate or because they were unclearly described.…”

“…The absence of the third molars in functional occlusion was due to extractions, impaction, or agenesis. One prospective longitudinal study did not divide the subjects into groups but used one side of the mandible as a control for the opposite side [15]. Subjects were followed up to detect the development of anterior tooth crowding for a defined period of time [2,5,15].…”

Subjects were followed up to detect the development of anterior tooth crowding for a defined period of time [2,5,15]. The retrospective longitudinal studies were carried out retrieving the clinical charts and dental models of orthodontically treated or untreated patients and assessing the association between the presence or absence of the third molars and the development of anterior tooth crowding [6,13,14,[16][17][18].…”

Indications d'avulsion des dents de sagesse mandibulaires dans le cadre militaire

“…Un exemple est prégnant dans le cadre de la prise de décision d'extraction par les chirurgiens dentistes : certains praticiens pensent que l'éruption des troisièmes molaires mandibulaires serait à l'origine du chevauchement des dents mandibulaires. L'implication des dents de sagesse dans l'encombrement dentaire est discutée depuis des décennies et aucune étude n'a apporté de preuve irréfutable, pourtant de nombreuses dents de sagesse sont encore extraites pour ce motif [108][109][110][111] . Par contre, si l'attitude pratique du corps médi-cal varie beaucoup, il n'en va pas de même des patients qui, conformément à ce que l'on peut penser, penchent très largement en faveur de la conservation de leurs dents de sagesse [112] .…”
