The conservative approach to managing unerupted lower premolars -- two case reports.
General dental practitioners frequently refer patients with unerupted premolars for specialist management. The frequency of unerupted lower second premolars in 15-year-old children has been cited as high as 9.7%. Two cases are discussed involving unilateral unerupted premolars, which initially appear to be in unfavourable positions. The first patient was referred at 16 years of age and presented with an unerupted lower left first premolar positioned along the lower border of the mandible. The second patient presented with an unerupted distally inclined, horizontally positioned second premolar impacting on the roots of the first permanent molar. Both cases were reviewed without any treatment, and both premolars erupted into excellent positions. This raises important questions concerning the possible treatment options for such teeth as well as the timing of any interceptive treatment. In cases where premolars are unerupted or impacted, a multidisciplinary approach is indicated involving orthodontics, paedodontics and oral surgery to establish the optimal treatment plan.
