Relationship between an Oral Health Risk Assessment Using a Salivary Multi-Test System and Woman’s Subjective Oral Health Symptoms and Sleep Disorder

Abstract

Saliva is used as a diagnosis and monitoring tool for various diseases because it can maintain the balance of the oral ecosystem and reflect the physiological and pathological state of the body. Because women suffer more fatigue than men because of physiological, psychological, and social factors, individual management strategies are needed to evaluate mental health and oral diseases. Therefore, this study examined the oral health risk level from seven saliva factors using a saliva multi-test system for adult women to confirm the possibility of screening for sleep disorders. The saliva of 83 adult female participants was surveyed along with a self-reported questionnaire consisting of seven subjective oral health symptoms and three questions about sleep disorders. Seven saliva factors were evaluated using the saliva multi-test system (SiLL-Ha ST-4910) to assess the oral health risk levels. In the tooth health risk groups, the acidity was high, while the buffering capacity was low (p < 0.001). The periodontal health risk groups showed significant differences in acidity, occult blood, leukocytes, proteins, and ammonia (p < 0.05). The oral malodor risk group had higher levels of cariogenic bacteria, occult blood, leukocytes, and ammonia (p < 0.05). In groups with ‘irregular sleep times’ and ‘insomnia’, the acidity was high, and the buffering capacity was low (p < 0.001). This study confirmed the relevance of saliva factors and sleep disorder. Therefore, an evaluation using saliva was confirmed for oral health risk assessments and as an early screening tool for sleep disorders.
