Clinical TrialTreatment of severe drooling with botulinum toxin in amyotrophic lateral sclerosis and Parkinson's disease: efficacy and possible mechanisms.
Drooling in neurodegenerative diseases is associated with social impediment. Previous treatments of drooling have little effect or are effective but with severe side effects. Therefore, there is a need to test new methods such as the use of botulinum toxin type A (BTX-A). ⋯ Inhibition of acetylcholine release from postganglionic parasympathetic nerve endings by injection of BTX-A into salivary glands seemed useful for secondary sialorrhoea, although cyclic variations in flow may occur, possibly due to transitory sprouting and regeneration.

Comparative StudyRisk factors associated with incidence and persistence of signs and symptoms of temporomandibular disorders.
To analyze whether gender, self-reported bruxism, and variations in dental occlusion predicted incidence and persistence of temporomandibular disorder (TMD) during a 2-year period. ⋯ This 2-year prospective observational study indicated that self-reported bruxism and variations in dental occlusion were linked to the incidence and persistence of TMJ signs and symptoms to a higher extent than to myofascial pain.

Comparative StudyAnalysis of masseter muscle oxygenation and mandibular movement during experimental gum chewing with different hardness.
The purpose of this study was to analyze masseter muscle oxygenation changes and mandibular movements in the experimental chewing of gums with different hardness. ⋯ The results suggest that the harder texture of gum enlarges chewing motion and increases chewing velocity, with an increase in the contribution of anaerobic metabolism to energy yield in masseter muscle. Differences in the responses to gum hardness may indicate individual differences in muscle fatigue tendencies when chewing harder foods.

Oral health impact on quality of life in an adult Swedish population.
Oral health has a major impact on general quality of life. The aspects of oral health that are most important for each individual vary, and quality of life is a construct and not a measurable variable. The aim of this study was to describe the impact of oral health on quality of life in an adult Swedish population. ⋯ In this Swedish population, a number of individuals, young and old, experienced oral problems that had an impact on their well-being.

Alexithymia refers to a personality construct that is characterized by impoverishment of imagination, poor capacity for symbolic thought, and inability to experience and describe feelings. Our aim was to investigate the association of alexithymia and dental anxiety in patients attending dental practice. A further aim was to discover whether gender differences exist in this association when adjusting for the effect of age. ⋯ In a sample representing Finnish adult dental patients, alexithymia was associated with dental anxiety.
