Over 5% of the world's population has disabling hearing loss. The oral health of the disabled may be disused for the reason of the disabling condition, a challenging disease or the limited access to oral health care.
The objectives of the study were to assess the prevalence of dental caries and periodontal status of institutionalized hearing impaired (HI) children in Khordha district of Odisha.
A descriptive cross-sectional study on the HI children was conducted in Khordha district, Odisha. Type III examination procedure was conducted to assess the oral health status of the children. Statistical analysis was performed by Chi-square test and Student's t-test, and the significance level was fixed at P < 0.05.
The final population consisted of 540 HI children out of which 262 (48.5%) were male and 278 (51.5%) were female, 285 (52.8%) children had severe hearing loss and 227 (42.0%) had profound hearing loss. Bleeding on probing was found in 72 (13.3%) female children as compared to 57 (10.6%) male children. While 131 (24.3%) female children had calculus, 124 (23.0%) male children had the same condition. Total caries prevalence was 19.3%. Statistically highly significant difference was found for mean decayed teeth (DT), missing teeth decayed, missing filled teeth (FT) (P < 0.001), while for mean FT there was no statistically significant difference according to age groups. Statistically highly significant difference was found for mean DT, extracted teeth and decayed, extracted, filled teeth (P < 0.001).
An improved accessibility to dental services as well as dental health education is necessary to ensure the optimum dental health within the reach of these less fortunate children.
全球超过5%的人口患有致残性听力损失。残疾人的口腔健康可能因致残状况、具有挑战性的疾病或获得口腔保健服务的机会有限而被忽视。
本研究的目的是评估奥里萨邦科德哈地区机构化听力受损（HI）儿童的龋齿患病率和牙周状况。
在奥里萨邦科德哈地区对HI儿童进行了一项描述性横断面研究。采用III型检查程序评估儿童的口腔健康状况。通过卡方检验和学生t检验进行统计分析，显著性水平设定为P<0.05。
最终研究对象为540名HI儿童，其中262名（48.5%）为男性，278名（51.5%）为女性，285名（52.8%）儿童患有重度听力损失，227名（42.0%）儿童患有极重度听力损失。与57名（10.6%）男性儿童相比，72名（13.3%）女性儿童探诊出血。131名（24.3%）女性儿童有牙结石，124名（23.0%）男性儿童有相同情况。总龋齿患病率为19.3%。在平均龋牙（DT）、缺失牙、龋失补牙（FT）方面发现统计学上的高度显著差异（P<0.001），而在平均FT方面，各年龄组之间没有统计学上的显著差异。在平均DT、拔牙数和龋拔补牙方面发现统计学上的高度显著差异（P<0.001）。
为确保这些不幸儿童能够获得最佳口腔健康，有必要改善牙科服务的可及性以及开展口腔健康教育。
