Oral Health Status, Treatment Needs and Oral Health Related Quality of Life among Hearing Impaired Adults in Riyadh City, Saudi Arabia

Abstract

The primary objective was to determine the oral health status and treatment needs among hearing-impaired (HI) adults. Second, to assess the relationship between the oral health variables and oral health-related quality of life (OHRQoL) by using General Oral Health Assessment Index (GOHAI)-Ar questionnaire among HI adults in Riyadh city, Saudi Arabia. A total of 146 HI adults between the age groups of 18-21, 22-25, and >25 years were included in the study. A convenient sampling technique was used to obtain the study sample. Oral health condition was recorded by using oral hygiene index-simplified (OHI-S), plaque index (PI), and gingival index (GI). The WHO methodology was used to record dental caries and treatment needs. The Saudi Arabian version of GOHAI-Ar questionnaire was used to gather information with regard to OHRQoL. A sign language expert communicated information between HI and investigator while answering the questionnaire. More than half of the HI had fair OHI-S (55.2%) and PI score (54.2%), while 60.1% of HI had moderate gingival inflammation. The prevalence of dental caries (82.2%) and treatment needs (85.6%) were found to be high. Mean oral hygiene scores between Saudi and non-Saudi nationals [(1.64) vs (1.12), p = 0.041] showed significant differences. Missing and filled teeth showed significant differences across different age groups (p = 0.000). The mean GOHAI-Ar was found to be low (14.44 ± 9.59). Spearman's test showed a significant positive correlation between the GOHAI-Ar score and the toothbrushing method (r = 0.164, p = 0.047). Toothbrushing time, oral hygiene material, last visit to dentist, OHI-S score, PI score, decayed, missing, and decayed missing filled teeth (DMFT) scores were negatively correlated with GOHAI-Ar. Speech was the main concern for the HI. There was a fair oral hygiene, moderate gingival inflammation, high caries experience, and treatment needs with low GOHAI-Ar scores indicating poor OHRQoL among HI.
