Cluster headache following dental treatment: a case report

Shoji Y

J Oral Sci, 2011 Mar;53(1):125-7.

Cluster headache is a neurovascular disorder characterized by attacks of severe and strictly unilateral pain presenting in and around the orbit and temporal area. Attacks occur in series lasting for weeks or months separated by remission periods. An individual attack lasts 15-180 min with a frequency of once every other day to as often as 8 times per day. Ipsilateral radiation of the headache to orofacial regions, including the teeth, is not unusual. The area of involvement may obscure the diagnosis and lead to irreversible and unnecessary dental treatment. A case in which cluster attacks occurred immediately after a dental procedure is described.

Background: Saliva is a readily accessible biofluid that is important for the overall quality of life, func-tionally essential in the chewing, swallowing, tasting, regulation mouth flora and prevention of caries. The aim of this study is to assess the global metabolomic profile of saliva in healthy Malaysian adults. Methods: As a first step to determining and understanding the metabolomic profile of saliva in healthy Malaysian adults, we have collected saliva samples of 50 adults and measured the salivary metabolite to establish a profiling metabolite data, Human Metabolome Database (HMDB). Metabolites concentrations of saliva in healthy subjects were measured by using 1H NMR spectroscopy. Results: The results showed there was no significant inter-individual variations of the key metabolites observed among the healthy Malaysian adults and there was no significant variation of the metabolites between female and male subjects. Conclusion: The metabolomic profile of saliva in healthy Malaysian adults could be used to establish the metabolomic database and used as a comparison for future study of the saliva of specific diseases.

Fulltext Migraine masquerading as temporomandibular disorders: a case report

Migraine is a common disabling primary headache disorder. Ipsilateral radiation of pain to orofacial regions, including teeth, jaws and temporomandibular joints, although not a common complaint, could occur. The area of involvement may obscure the diagnosis and lead to unnecessary dental treatment. A case is presented in which a patient initially sought dental care for left jaw pain that radiated to her left maxillary teeth and temple region and she was also experiencing discomfort in the left masticatory musculature. Subsequently a medical consult diagnosed migraine headache without aura and fortunately unnecessary dental treatment was not done. The key issue here is the complexity of the Trigeminal nerve when the dentist is assessing a patient for dental or other orofacial pain complaints and dental pathology has been ruled out. Equally as important is the dentist taking thorough medical history since a patient may not tell a dentist about a “headache” because the pain is in the teeth and/or jaws. And, perhaps most important is the final differential diagnosis whether made by the dentist or medical care provider.

Occlusal force and occlusal contact reestablishment with resin-bonded fixed partial dental prostheses using the Dahl concept: A clinical study

STATEMENT OF PROBLEM: Space creation for a metal retainer of the resin-bonded fixed partial dental prostheses (RBFPDPs) with the Dahl concept remains controversial because of the lack of clinical studies.

PURPOSE: The purpose of this clinical study was to investigate the occlusal force and occlusal contact reestablishment of RBFPDPs cemented at an increased occlusal vertical dimension (the Dahl concept) and to evaluate the factors affecting them.

MATERIAL AND METHODS: A prospective clinical study was carried out on 28 participants receiving cantilevered RBFPDPs at an increased occlusal vertical dimension at the Faculty of Dentistry, University Teknologi MARA. Maximum occlusal forces were recorded at precementation, postcementation, and 12-week review visit by using pressure indicating film, while occlusal contact reestablishment was assessed at the precementation stage and 12-week review visit by using shim stock foils. The Wilcoxon signed-rank and chi-squared tests were used for statistical analysis (α=.05).

RESULTS: Significant differences were found for maximum occlusal force between the precementation and the postcementation and between the postcementation and the 12-week review of RBFPDPs (P.05).

CONCLUSIONS: Overall, occlusal force was reestablished after 12 weeks, and occlusal contact was completely reestablished in most participants after placement of RBFPDPs at an increased occlusal vertical dimension.

Fulltext Effect of age on bite force

This study compared bite force in adults older than 60 years with that of young adults. The participants were 20 healthy adults (9 men) older than 60 years (median age, 66 years) and 44 healthy young adults (22 men; age range, 18-25 years; median age, 22 years) at the International Medical University, Malaysia. All participants had at least 20 teeth, and bite force was measured and evaluated using the Dental Prescale system. Average (SD) bite force was 420.5 (242.0) N for the older adults and 541.4 (296.3) N for the young adults. Although mean bite force was higher for the young adults, the difference was not significant. These findings suggest that bite force is unaffected by age in adults with adequate dentition.
