BACKGROUND/AIM: Little is known about adult dental trauma experience at the population level. The aim of this study was to estimate the prevalence and associations of dental injuries in New Zealand (NZ) adults. MATERIALS AND METHOD: Information about dental and orofacial trauma in a representative sample of NZ adults (ages 18-94) was collected in a national oral health survey. As well as self-reported information, the maxillary six anterior teeth were examined for signs of dental trauma. Survey weights were used.
RESULTS: Of the 40.9% (95% CI 37.6, 44.2) who reported previous orofacial trauma, 69.1% (95% CI 64.3, 73.5), or just over one-quarter of the sample, reported that this included a dental injury. More males than females had experienced orofacial trauma (51.3% [95% CI 45.8, 56.8] and 31.4% [95% CI 27.9, 35.1] respectively). The most common injury was a "chipped or broken tooth" (66.6%, 95% CI 60.6, 72.1). Almost three-quarters had sought treatment. Clinical examination revealed an overall trauma prevalence of 23.4% (95% CI 21.0, 26.0) with more males than females affected. Some 14.9% (95% CI 12.8, 17.2) had one injured tooth, while 6.5% (95% CI 5.2, 8.1) had two injured teeth. The maxillary central incisors were the most frequently affected. Most participants with clinical signs of trauma had only one of the six maxillary teeth affected. The most common clinical dental trauma observation was evidence of "treatment" or an "untreated enamel fracture", and these were more common among males and those aged 35-44 years.
CONCLUSION: Traumatic dental injuries constitute an important public health issue. More emphasis on preventing them in the NZ adult population is warranted, and public awareness of State-funded cover for dental injuries may need to be bolstered to enable equitable access for injury care. Overall, a greater emphasis on prevention and the importance of initial care for dental injuries could reduce the individual and societal burden.
