Oral health status, behavior, and practices among hearing impaired children attending a specialized school in Jordan.

Aims: To assess the oral health status and related factors among hearing impaired schoolchildren.

Methods: A cross-sectional study among 115 hearing impaired schoolchildren enrolled at the School of the Deaf in Jordan. The World Health Organization (WHO) methodology and criteria were applied to collect data on caries, gingival bleeding. The WHO classification modified by Andreasen et al. was used to record traumatic dental injuries (TDIs). Sociodemographic data, oral health practices, and oral health related quality of life information were collected using a structured questionnaire.

Results: The prevalence of caries among the study sample was 84.3%, the dominating component was untreated dental caries. Mean decayed, missing, filled primary teeth (dmft) was 8 in the primary dentition and 3.62 in the mixed dentition, mean Decayed, Missing, Filled permanent Teeth (DMFT) was 1.38 in the mixed dentition and 2.87 in the permanent. The overall mean of gingival bleeding percentage among the whole study sample was 70.38%. the prevalence of TDIs was of 11.3% and mostly caused by falls.

Conclusions: The prevalence of dental caries and caries experience, rate of gingival bleeding and dental trauma in children with hearing impaired individuals are high compared to figures observed in studies conducted among Jordanian schoolchildren with normal hearing. Dental diseases impact the quality of life of these individuals.
