Cross-sectional analysis of dental treatment under general anaesthesia in hospitalised Western Australian children in 2018–19.

Objective: To date, there has been little research that has comprehensively analysed dental treatment under general anaesthesia (DGA) at Perth Children's Hospital (PCH) for dental emergencies (dental pain and sepsis). This cross-sectional descriptive analysis of the PCH dental department analysed the demographic of children admitted and the type of treatment used, and assessed the cost. Methods: This was a retrospective descriptive study analysing the dental records of patients ranging from 2 to 16 years of age at PCH in Western Australia. Of the 310 cases randomly selected from the 2018–19 study period, 202 were admitted for DGA. Two outcome measures were derived: cumulative count of treatment mix and cost analysis. Results: The mean (±s.d.) age at the time of admission was 6.2 ± 2.6 years and the mean (±s.d.) decayed (d/D), missing, (m/M) and filled (f/F) teeth (dmft/DMFT) was 2.1 ± 0.8. Of the 429 teeth affected, 282 were molars. Treatments were grouped therapeutically; of the 856 treatments performed, 465 were extractions (54%). The total cost, consisting of direct and indirect costs, was A$313 823, and equated to an approximate mean (±s.d.) of A$1554 ± 109 per case. Conclusion: Untreated dental caries was the most common cause for hospital admission. Most cases presenting at the emergency department were young children (<7 years old) who underwent extractions under DGA. What is known about the topic?: The Child Dental Benefits Schedule (CDBS) was introduced to improve access and affordability to oral health care for children without private dental insurance. However, a significant number of children are still being admitted to hospital for emergency dental treatment. What does this paper add?: Despite the availability of the CDBS, untreated dental caries remains one of the most common reasons for dental emergency in the PCH. What are the implications for practitioners?: Not only are direct costs a burden on the health budget, but indirect and intangible costs also affect children and their families. [ABSTRACT FROM AUTHOR]
