A smaller study but nicely done with approximately three dozen participants. Probably one of the first of its kind that showed through quantitative sensory testing that post-menopausal women suffering from burning mouth syndrome respond more to noxious thermal stimuli applied to the tongue. The study may support the hypothesis that fluctuations in sex hormones affect somatosensory function in the trigeminal distribution. This is especially so in women in the late post-menopausal stage and affected by BMS.
A thorough and well written comprehensive narrative review of the orofacial manifestations of two most prevalent autoimmune diseases, namely rheumatoid arthritis and systemic lupus erythematosus. Special mention should be made of the fact brought out in this article that the prevalence of RA in general population is 1% ! Considering the fact that one out of every hundred patients a dental clinician sees in his general practice has RA, the food for thought is what percentage of patients seen in an orofacial pain specialty practice would have RA? It is conceivable that this percentage will be much higher. The article brings to attention of the OFP specialists the significance of systemic factors in the causation of orofacial pain.
Obstructive sleep apnea has been known to be associated with sleep related bruxism. This study measuring apnea-hypopnea index (AHI) and sleep bruxism index (SBI) showed no correlation between AHI and SBI. The patients with severe apnea showed a tendency to have higher bruxism index. However, there was no correlation between AHI and SBI.
In the orofacial pain field, traditionally, the masseter muscle has been divided into superficial and deep layers. The possibility of a third layer was mentioned in a few historical texts. This anatomical study is probably the first of its kind that showed a distinct third layer of the masseter muscle. The existence of the third layer is consistent in every human cadaver examined; the muscle layer is attached on the medial surface of the zygomatic process of the temporal bone to the root and posterior margin of the coronoid process. The arrangement of the fibers suggests its involvement in stabilizing the mandible by elevating and retracting the coronoid process.
This narrative review summarizes the data on the effect of light on migraine patients. Light has been reported as a trigger for migraine attacks. This article shows that photophobia being an early manifestation is a false attribution, contrary to this belief. Migraineurs are not equally photophobic to all wave bands of the light spectrum. With regards to this, the suggestion is to use human-centric lighting (“integrative lighting”) that mimics natural daylight, and thereby avoiding harmful light wave bands.
