Some studies have shown a relationship between temporomandibular disorders (TMD) and dysphonia, as well as quality of life in oral health.
The purpose of this study was to investigate the correlation between severity of vocal self-perception and TMD severity and the correlation between oral health-related quality of life impairment and TMD severity.
Thirty-three women aged 20 to 40 years, with or without complaint of dysphonia, were recruited at the Bauru campus of the University of São Paulo, Brazil, and the local community. All participants were subjected to an investigation of quality of life related to dental and speech aspects by the application of Oral Health Impact Profile-short form (OHIP-14) and the Voice-Related Quality of Life (V-RQOL) protocol. Also, a questionnaire was applied to detect the presence and severity of TMD.
There was significant correlation between TMD and quality of life for all aspects analyzed in the oral health protocol, except for function and physical limitation (p>0.05). There was negative correlation between TMD and voice-related quality of life in the total score (p=0.007) as weel as physical (p=0.008) and socio-emotional aspects (p=0.017). In addition, there was statistically significant correlation between TMD and vocal self-perception (p=0.037).
There is an association between TMD severity, voice-related and oral health-related quality of life. It is important to investigate in future studies the vocal self perception as well as the oral and voice conditions in patients with TMD.
摘要：一些研究表明，颞下颌关节紊乱（TMD）与发音障碍以及口腔健康的生活质量之间存在一定关系。
目的：本研究旨在探讨嗓音自我感知严重程度与 TMD 严重程度之间的相关性，以及口腔健康相关生活质量受损与 TMD 严重程度之间的相关性。
材料和方法：在巴西圣保罗大学的 Bauru 校区和当地社区，共招募了 33 名年龄在 20 至 40 岁之间、有或没有发音障碍的女性。所有参与者都接受了口腔健康相关的生活质量评估，包括通过应用口腔健康影响简表（OHIP-14）和嗓音相关生活质量（V-RQOL）量表进行的口腔和语音方面的评估。此外，还应用问卷来检测 TMD 的存在和严重程度。
结果：在口腔健康协议中分析的所有方面中，TMD 与生活质量之间均存在显著相关性，除了功能和身体限制方面（p>0.05）。在总分（p=0.007）以及身体（p=0.008）和社会情感方面（p=0.017），TMD 与嗓音相关的生活质量之间存在负相关。此外，TMD 与嗓音自我感知之间存在统计学显著相关性（p=0.037）。
结论：TMD 严重程度与嗓音相关和口腔健康相关的生活质量之间存在关联。未来的研究中，有必要进一步调查 TMD 患者的嗓音自我感知以及口腔和嗓音状况。
