Background/AimInjuries to the primary dentition affect children's esthetics, function, and mental health. They may also affect the development of the permanent teeth. The knowledge of dentists about deciduous tooth trauma is rarely evaluated. The aim of this study was to evaluate the knowledge and attitude of dentists in China regarding traumatic dental injuries to primary teeth.Material And MethodsA self-administered online questionnaire containing questions on demographic data and knowledge based on a clinical scenario was given to a purposive sample of dentists, recruited by a non-probability convenience sampling method. The chi-square test was used for statistical analysis, with the significance level set at P <.05.ResultsA total of 394 out of 409 dentists provided valid data. There was no significant difference in demographic data. Questions about the treatment of hard dental tissue injuries in primary teeth presented a correct-response rate of 66.4%, with the highest correct-response rate for enamel fracture (n = 368, 93.4%) and lowest for complicated crown-root fracture with pulp exposure (n = 104, 26.4%). Questions about treatment of luxation injuries in primary teeth presented a correct-response rate of 66.6%, with subluxation presenting the highest correct-response rate (n = 391, 99.2%). Factors associated with higher correct-response rates were specialist disciplines, educational qualifications, workplaces, experience of injured teeth treated, and educational experience about primary tooth trauma. No significant differences were found in the correct-response rates of dentists with different years of work experience. Lack of cooperation from children was considered a major obstacle for treatment. Special lectures and Internet courses were the most preferred methods of obtaining knowledge.ConclusionThe results suggest that it is necessary to enhance dental trauma education for dentists in China. More attention needs to be paid to trauma in primary dentition to ensure adequate treatment for traumatized primary teeth.© 2020 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.
