Abstract

The mentophysical disease causes diseases in digestive, respiratory, circulating systems, including chronic pain, through combined reactions from different individual characteristics, mental stress and temperamental factors. The most common symptom related to orofacial area is pain and the contributive factors include biological, behavioral, environmental, social, emotional, recognitive factors. These factors affect the course of the symptom according to individual's character and human nature. In pain, sleep acts as a contributive factor, and pain could bring about sleep disturbance and vice versa. Deterioration of sleep quality would act as a factor that aggravates mental stress. Therefore, relatively accurate and simple mental examinations and sleep quality test should be carried out for the patients with symptoms related to orofacial area. This study evaluated the mental state in relation to the sleep quality which could affect orofacial pain. The number of poor sleeper was 18 in male subjects, and 1 in female subjects and PSQI global index was higher in male($6.11{\pm}2.38$) than female($4.67{\pm}2.18$). SCL-90-R index showed no sex difference. Poor sleeper showed significantly high value in SOM, O-C, I-S, ANX, PHOB, PSY, GSI, PST. When SCL-90-R T scores were compared according to sleep quality, higher the subjective sleep quality score, O-C and I-S showed significant increase. As sleep disturbances score increased, PAR, PSY, PST showed statistically significant increase. In comparison of SCL-90-R T score according to daytime dysfunction, statistically significant increase in DEP, ANX, HOS, PHOB, PAR, GSI was observed. Therefore, the quality of sleep and psychological status have a high correlation. This is likely to influence chronic pain in the orofacial field. As a result, clinicians treating orofacial pain should evaluate the sleep quality and psychological status of the patient. Further studies of larger sample sizes including various age, occupation, and pain groups are necessary in order to apply the results to clinical practice.

정신신체질환은 개개인의 서로 다른 성격, 정서적 스트레스에 대한 반응과 기질적인 요소 등이 함께 반응하여 소화기계, 순환기계, 호흡기계 및 근골격계 등에 수많은 질환을 야기하며, 그 중에 만성통증도 역시 포함한다. 구강안면 영역의 증상으로 내원하는 이유 중 가장 많은 비율을 차지하는 것은 통증이며 증상에 영향을 주는 기여요인은 생물학적 요인, 행동요인, 환경요인, 사회요인, 정서요인, 인지요인 등을 포함한다. 이러한 기여요인은 개인의 성격, 인성에 좌우되어 증상의 경로에 영향을 미치게 된다. 통증에 있어 수면은 하나의 기여요인으로 작용하며, 통증은 수면장애를 가져오거나 악화시키기도 하며, 수면장애 역시 통증을 악화시킬 수 있다. 수면의 질의 저하는 정서적 스트레스를 가속화 시킬 수 있는 한 요인으로 작용할 수 있다. 이에 구강안면 영역에 증상을 보이는 환자에게 비교적 정확하고 간단하게 시행할 수 있는 수면의 질 평가 및 정신 검사를 필히 시행하여 평가해야 한다. 본 연구는 PSQI를 통한 수면의 질 평가와 간이정신진단검사(SCL-90-R)를 비교 평가하여 수면과 정서적, 심리적 상태와의 관계를 규명하고자 하였으며, 다음과 같은 결과를 얻었다. poor sleeper 는 남자가 18명, 여자가 1명이었으며, PSQI 총수면 지수는 남자에서 $6.11{\pm}2.38$, 여자에서 $4.67{\pm}2.18$로 나타났다. SCL-90-R 지수는 남녀간 차이를 보이지 않았고 poor sleeper에서 신체화(SOM), 강박증(O-C), 대인예민성(I-S), 불안(ANX), 공포불안(PHOB), 정신증(PSY)에서 유의성 있게 높은 평균치를 보였으며 전체 심도지수(GSI), 표출증상합계(PST)가 유의성 있게 높았다. 또한 수면의 질에 따른 SCL-90-R의 T-점수는 주관적 수면의 질이 나쁠수록 강박증(O-C), 대인 예민성(I-S)에서, 수면장애가 심할수록 편집증(PAR), 정신증(PSY), 표출증상합계(Positive symptom total, PST)가, 주간수면장애에서는 우울(DEP), 불안(ANX), 적대감(HOS), 공포불안(PHOB), 편집증(PAR), 전체 심도지수(GSI)에서 유의하게 높은 평균치를 보였다. 이와 같이 수면의 질과 정서적 상태는 서로 밀접한 연관성을 지닌다고 할 수 있으며, 이는 구강안면 영역의 만성 통증에 영향을 미치리라 생각된다. 이에 구강안면통증을 다루는 임상가들은 환자의 수면의 질과 정서적 상태에 대해 적절히 평가하는 것이 반드시 필요하며, 추후 구강안면통증에 있어 수면과 정서적, 심리적 인성관계에 대한 연구가 더 필요하리라 사료된다.
