Abstract：
OBJECTIVE: Individuals with special needs requiring special care are more vulnerable to oral health problems. Sign language is a communication medium and language of instruction for individuals with hearing impairments. The purpose of this systematic review and meta-analysis was to assess the effectiveness of sign language-based educational interventions compared to other educational interventions in improving the oral health of hearing-impaired individuals.
METHODS: PubMed, Scopus, Embase, and Cochrane Central Register of Controlled Trials databases were searched without any restriction on the publication date. Analytical and experimental studies that evaluated and compared the effectiveness of sign language with other educational intervention groups such as videos, posters etc were included.
RESULTS: Initially, 5568 records were identified. Three relevant publications from India were eligible and included in the systematic review and meta-analysis. Differences were reported in favour of sign language over other interventions concerning plaque status, gingival health, and oral hygiene status.
CONCLUSIONS: Sign language-based interventions were found to be effective. However, further studies in different locations and populations are required to support their effectiveness.

摘要：
目的：有特殊需要需要特殊护理的人更容易受到口腔健康问题的影响。手语是听力障碍个人的交流媒介和教学语言。这项系统评价和荟萃分析的目的是评估与其他教育干预措施相比，基于手语的教育干预措施在改善听力受损者口腔健康方面的有效性。
方法：PubMed，Scopus,Embase,和Cochrane中央对照试验注册数据库的搜索没有任何限制的发布日期。分析和实验研究，评估和比较手语的有效性与其他教育干预组，如视频，海报等都包括在内。
结果：最初，确定了5568条记录。来自印度的三份相关出版物符合资格，并纳入系统评价和荟萃分析。据报道，与其他有关斑块状况的干预措施相比，手语有所差异，牙龈健康，和口腔卫生状况。
结论：发现基于手语的干预措施是有效的。然而,需要在不同的地点和人群中进行进一步的研究以支持其有效性。
