RESUMO
This study compared the presence of headache and bruxing behavior among 133 craniomandibular disorder patients (CMD) referred to the The Center For the Study Of Craniomandibular Disorders and to the presence of headache and bruxing behavior occurring in 133 controls seeking routine dental care. Both patients and controls were consecutive referrals to the clinic occurring over a three year period. The mean age of the CMD group was 38 years (range 28-42), and the mean age of the controls was 37 years (range 25-44). The information gathered included questionnaire and clinical examination. Different types of headaches, signs and symptoms of CMD, and bruxing behavior were assessed both in the CMD group and in the corresponding control group. Results of this study showed that bruxing behavior and headache pain were significantly more prevalent in the CMD group (57%, 76%) than in the corresponding control group (37%, 49%). Of the three types of headache observed, tension and combination headaches were more prevalent in the CMD group (n = 48 = 36% and n = 37 = 28%). Migraine headache was more prevalent in the CMD group (n = 16 = 12%) than in the control group (n = 3 = 2%). It was concluded that headache and bruxing behavior predominated in CMD patients. This data reinforces the need to assess headache pain and signs and symptoms of bruxing behavior in CMD patients, particularly in those suffering chronic facial pain and headache.

Periodontal disease in the domestic cat may assume debilitating and serious consequences; however, little is known of the biochemical composition or metabolism of feline gingiva in health or disease. In this report the chemical composition and metabolism of gingival lipids from inflamed an non-inflamed sites is presented and compared to other species with naturally occurring periodontitis. The neutral and phospholipid composition of feline gingiva was found to be distinct from that of porcine and human. As a measure of de novo lipid synthesis, the total incorporation of 14C-acetate into fractionated lipid components was determined and revealed an approximate 2 to 3 fold decrease in inflamed versus non-inflamed gingiva. The decrease in 14C-acetate incorporation appeared to result from a 2-fold increase in free acetate pools in inflamed compared to non-inflamed gingival samples, since total lipase and phospholipase activity were comparable in inflamed and non-inflamed gingiva and total lipid composition was not changed between inflamed and non-inflamed sites. These data are similar to those reported for periodontally involved human gingival tissue and suggest a common effect of periodontal inflammation on lipid metabolism in both species.
