Background: The oral condition can functionally, socially and psychologically influence the quality of life. Oral dryness often occurs in the elderly due to the presence of systemic diseases and medications, which favors the development of many lesions and complaints, including dental caries, candidiasis, retention of full removable denture, taste disturbance and it enforces a change in nutrition.

Objectives: The aim of this study was to assess the impact of oral dryness on oral health-related quality of life in older subjects.

Oral health condition and occurrence of depression in the elderly.

Depression can affect oral health as a result of neglecting oral hygiene procedures, cariogenic nutrition, avoidance of necessary dental care which leads to an increased risk of dental caries and periodontal disease.Assessment of the relationship of oral health parameters with depression.

The Co-Occurrence of Sexsomnia, Sleep Bruxism and Other Sleep Disorders.

Background: Sleep sex also known as sexsomnia or somnambulistic sexual behavior is proposed to be classified as NREM (non-rapid eye movement) parasomnia (as a clinical subtype of disorders of arousal from NREM sleep-primarily confusional arousals or less commonly sleepwalking), but it has also been described in relation to REM (rapid eye movement) parasomnias.

Methods: The authors searched the PubMed database to identify relevant publications and present the co-occurrence of sexsomnia and other sleep disorders as a non-systematic review with case series.

Results: In the available literature the comorbidity of sexsomnia and other sleep disorders were reported mainly in case reports and less in case series.
