Management of asymptomatic impacted wisdom teeth: A multicentre comparison

This study was carried out to assess the opinions of clinicians (general practitioners and oral and maxillofacial surgeons) regarding the management of unerupted Mandibular Asymptomatic Impacted Wisdom Teeth (MAIWT) at two centres: Glasgow Dental Hospital and School and its affiliated institutions and Prince Philip Dental Hospital and its affiliated institutions in Hong Kong. Twenty four clinicians, twelve from each centre, of whom six were oral and maxillofacial surgeons (OMS) and six general dental practitioners (GDP) participated in this investigation. The orthopantomographs of 21 cases mere used in the study and were examined by each clinician to investigate the management of unerupted MAIWT was recorded using a custom written questionnaire. Hong Kong clinicians showed a greater tendency towards extraction of MAIWT in comparison to Glasgow clinicians. The difference was statistically significant. The data indicates a significant difference between Hong Kong OMS and Glasgow OMS and between Hong Kong OMS and Hong Kong GDP, with Hong Kong OMS showing a greater tendency towards extraction. This study proved the diversity of opinions in one of the most common dento-alveolar procedures. The dilemma to extract or retain MAIWT still exists and controversy is likely to remain. The difference in the rationale of management regimes between the centres are discussed. The medico-legal and financial issues are investigated.
