The aims of this study were firstly to determine the fate of unerupted permanent maxillary incisor teeth following
supernumerary tooth removal and secondly to make recommendations regarding the management of such incisor teeth following
supernumerary tooth extraction. STUDY DESIGN: This is a retrospective study..
Records of children attending the
Departments of Paediatric Dentistry, Edinburgh Dental Institute, Lothian Primary Care NHS Trust and Dundee Dental Hospital, Tayside
University Hospitals Trust between 1995 and 2002 were examined with regard to non-eruption of one or both maxillary central incisors
in association with supernumerary teeth requiring surgical removal. Subsequent permanent maxillary incisor eruption was recorded and
in those cases of incisor non-eruption, further surgical interventions were noted.
In all 118 sets of patient records were
included in the study (87 males, 31 females) with a mean age at presentation of 8.8 years (range 5.3-11.6 years). Failure of eruption of
the associated permanent maxillary central incisor teeth occurred in 27 of cases, in relation to both conical and tuberculate
supernumerary teeth. All tuberculate supernumerary teeth associated with non-eruption cases were palatally placed and 59
were adjacent to maxillary incisors with near complete apex formation. To facilitate incisor eruption in these cases, 41 required
surgical exposure of the non-erupted incisor tooth and 59 required surgical exposure with bonding of an orthodontic bracket and
gold chain for orthodontic traction.
Non-erupted permanent maxillary incisor teeth with near complete apical formation,
associated with palatally placed, tuberculate-shaped supernumerary teeth, may benefit from having an orthodontic bracket and gold
chain placed at the same time as the surgical procedure to remove the supernumerary tooth to facilitate future orthodontic
