To examine and compare practitioners' judgements of risk of future pathology associated with pathology-free disease asymptomatic third molars.
10 oral and maxillofacial surgeons and 18 family dentists (90% male) with experience ranging from 5-28 years.
Participants were presented with periapical radiographs of 36 asymptomatic, disease-free mandibular third molars and were informed of the age and sex of the patients and the degree of eruption of the third molars. Participants were asked to assess likelihood of future pathology in general, and more specifically, likelihood of root resorption, pericoronitis, periodontitis, cystic change and neoplasia if the third molar was left in situ.
There was significant variation between the 28 raters but not between the two groups. Excepting assessment of future cystic change, there was no evidence that oral and maxillofacial surgeons and family dentists rated the 36 cases in consistently different ways.
Practitioners varied very considerably in their judgment of the risks of pathology associated with asymptomatic disease-free third molars. Specialisation, did not account for this variation.
检查并比较从业者对无症状且无病变的第三磨牙未来发生病变风险的判断。
10名口腔颌面外科医生和18名全科牙医（90%为男性），从业经验在5至28年之间。
向参与者展示36例无症状、无病变的下颌第三磨牙的根尖片，并告知患者的年龄、性别以及第三磨牙的萌出程度。要求参与者评估总体上未来发生病变的可能性，更具体地说，评估如果第三磨牙保留在原位，发生牙根吸收、冠周炎、牙周炎、囊性改变和肿瘤形成的可能性。
28名评估者之间存在显著差异，但两组之间无差异。除了对未来囊性改变的评估外，没有证据表明口腔颌面外科医生和全科牙医对这36例病例的评分方式存在持续的差异。
从业者对无症状且无病变的第三磨牙发生病变风险的判断差异很大。专业领域并不能解释这种差异。
