In 2003, reports came about that identified cases of osteonecrosis of the jaws in patients being treated with bisphosphonate medications, such as zoledronic acid (Zometa, Novartis, East Hanover, NJ), pamidronate (Aredia, Novartis, East Hanover, NJ), alendronate (Fosamax, Merck and Co., Whitehouse Station, NJ), and risedronate (Actonel, Proctor & Gamble Pharmaceuticals, Cincinnati, Ohio) for a variety of diagnoses, typically metastatic breast cancer, multiple myeloma, and osteoporosis. The first report, an abstract presented by a member of the ...

In my previous editorial (CRANIO, Vol. 27, No. 2, pp 73-74), I discussed some of my ideas on how to not just survive but thrive in hard economic times. I would like to say that things have improved in this country but, from my perspective, I feel that the situation is worse than ever.

Our country is polarized. Instead of coming together, we seem to be more apart than ever. We have politicians who would ...

Anterior crossbite (ACB) malocclusions are frequent; however, its characteristic functional features have not been fully described. The purpose of this study was to determine the characteristics of habitual mandibular open-close motion in children with ACB of their primary dentition. Two groups of children were selected for study; 17 with ACB (eight boys and nine girls; four years one month to seven years one month) and 19 with normal occlusion (eight boys and 11 girls; four ...

This study was undertaken to characterize jaw motion during mastication in children with primary dentition and to compare jaw motion with that in adults. The means and the variances of the traditional parameters for the chewing cycle, i.e., duration, excursive ranges and 3-D distances of travel at the lower incisor, molars and condyles were analyzed and compared in 23 children and 25 female adults. The duration of opening in children was significantly shorter than ...

This study evaluated the use of a fixed orthodontic appliance in treatment of temporomandibular disorder (TMD) compared to the use of an intra-oral splint. Fifty (50) adult patients, with confirmed anterior disk displacement with reduction in at least one temporomandibular joint (TMJ), were divided into three groups: 20 patients treated with AR splint (Group I); 20 patients treated with a fixed orthodontic appliance (Group II) and 10 patients who underwent no treatment (Control Group). Joint ...

The aim of this study was to determine the effect of tooth clenching and grinding on anterior temporalis electromyographic (EMG) activity. The sample included 30 healthy subjects with natural dentition and bilateral molar support, 15 with bilateral canine guidance and 15 with bilateral group function. An inclusion criterion was that subjects have to be free of signs and symptoms of any dysfunction of the masticatory system. Bipolar surface electrodes were located on the left and ...

It is not uncommon for practitioners who treat craniofacial pain to see patients with undiagnosed throat and submandibular pain. Usually, these patients will already have been seen by their primary care physician and frequently, several others doctors including otolaryngologists, oral and maxillofacial surgeons, and even neurologists. Far too often these patients have three common features: 1. they have endured multiple expensive diagnostic tests; 2. they have received treatment of multiple courses of antibiotics; and 3 ...

The specific aims of the study were to determine (1) the mean condylar path inclination (CP) and Bennett angles (BA) in occlusally healthy dentate subjects and (2) whether there was right-left asymmetry of CP and BA. Eccentric movements of three mm and five mm from reference positions were recorded for 45 subjects using a Cadiax system. The mean right CP angles: 48.8±8° (three mm) and 48.2±7° (five mm); the mean left ...

Synovial chondromatosis of the temporomandibular joint (TMJ) is a rare lesion characterized by the presence of loose bodies in the glenoid fossa. Swelling, unilateral pain, occlusal changes, clicking, crepitation, deviation, and limited mandibular function are the most common characteristics, although this combination is not always apparent. Radiopacities of the TMJ should be thoroughly investigated as some signals and symptoms may be not present or combined, taking months or even years to confirm a diagnosis. A ...
