BACKGROUND/AIMS: The prevalence of work-related oral trauma is underestimated because minor dental injuries are often not reported in patients with several injuries in different parts of the body. In addition, little data are available regarding their characteristics. The aim of this epidemiological study was to determine the prevalence, types and characteristics of occupational traumatic dental injuries (TDIs) in a large working community.
MATERIALS AND METHODS: Work-related TDIs that occurred during the period between 2011 and 2013 in the District of Genoa (Northwest of Italy, 0.86 million inhabitants) were analyzed. Patients' data were obtained from the National Institute for Insurance against Accidents at Work database.
RESULTS: During the 2 years period, 112 TDIs (345 traumatized teeth) were recorded. The prevalence was 5.6‰ of the total amount of occupational trauma. The highest prevalence was found in the fourth and fifth decades of life (OR=3.6, p<0.001) and males were injured more often than females (70.5% vs 29.5%, OR=2.8, p<0.001). Service and office workers represented 52% of the sample and construction/farm/factory workers and craftsmen were 48%. TDIs involved only teeth and surrounding tissue in 66% of cases, or in combination with another maxillofacial injury in 34%. They were statistically associated with construction/farm/factory workers group (Chi2 p<0.01). Crown fracture was recorded in 34.5% of cases, subluxation/luxation in 10.7%, avulsion in 9%, root fracture in 3.8% and concussion in 3.5%. Thirty-two subjects (28.6%, 133 teeth, OR=4.3, p<0.001) presented at least 1 traumatized tooth with previous dental treatment. Among 212 (61.4%) traumatized teeth, 67.5% were upper incisors, 17.5% were lower incisors, 3.3% were upper canines, 1.9% were lower canines and 9.9% were bicuspids and molars.
CONCLUSIONS: Work-related TDIs had a low overall prevalence and fractures were the most frequent dental injury. Age, gender and pre-exiting dental treatments represented risk factors for work-related TDIs. This article is protected by copyright. All rights reserved.
