Background Hall technique preformed metal crowns (HTPMCs) have been increasing in use recently, but little is currently known about their use by specialists.Aim To investigate the views and usage of HTPMCs by UK specialist paediatric dentists.Design This was a prospective questionnaire-based study, distributed online to all specialists on the British Society of Paediatric Dentistry email list between July and September 2014.Results Ninety-four questionnaires were completed. The majority of respondents, 65% (61) worked in teaching hospitals, followed by community dental services, 37% (35). Ninety-six percent (89) reported that they used HTPMCs in their practice. Fifty-eight percent (54) used HTPMCs as a treatment option for restoring symptomless carious primary molars, and 15% (14) only when unable to provide conventional restoration. Twenty-three percent (21) used HTPMCs as the treatment of choice. Only 4% (4) of respondents never used them. Sixty percent (53) had been using HTPMCs for over five years. Seventy-six percent (68) would consider placing HTPMCs under inhalation sedation, and 26% (23) under general anaesthesia. Over 90% (85) believed that HTPMCs are suitable for undergraduate teaching, general practice, postgraduate training and specialist practice.Conclusion HTPMCs are widely used among specialist paediatric dentists in the UK.
背景 预成金属冠（HTPMCs）的霍尔技术最近使用越来越多，但目前对于专科医生使用此类冠的情况知之甚少。
