Osteoarthritis of the temporomandibular joint and increase of the horizontal condylar angle: a longitudinal study.

Objective: Our previous study of patients with unilateral temporomandibular joint (TMJ) osteoarthritis (OA) showed that the affected joints had greater horizontal condylar angle (HCA) compared with the contralateral unaffected joints. However, it was unclear whether the HCA changes preceded or were the result of OA changes. The aim of this longitudinal study was to investigate the relationship between HCA and OA progression.

The Incidence of Second Mesiobuccal Canals Located in Maxillary Molars with the Aid of Cone-beam Computed Tomography.

Introduction: Many endodontic treatment failures in maxillary molars result from missed second mesiobuccal (MB2) canals. An MB2 canal orifice is present in as many as 95% of maxillary molars, but these canals are not always located during endodontic procedures. Additional tools, such as cone-beam computed tomographic (CBCT) imaging, may be needed to locate these canals in maxillary molars.

Greater mandibular horizontal condylar angle is associated with temporomandibular joint osteoarthritis.

Background: Research using magnetic resonance imaging analysis has shown that internal temporomandibular joint derangement is associated with significantly greater horizontal condylar angle. However, the association between osteoarthritic (OA) bony changes as shown on computed tomography and horizontal condylar angle has never been evaluated.

Objective: To investigate the relationship between mandibular condylar angle and OA degenerative changes.

Satisfaction and Clinical Outcomes Among Patients with Immediately Loaded Mandibular Overdentures Supported by One or Two Dental Implants: Results of a 5-Year Prospective Randomized Clinical Trial.

Purpose: The purpose of this study was to evaluate patient satisfaction and clinical outcomes among subjects with mandibular overdentures supported by one or two immediately placed dental implants 5 years after loading.

Materials And Methods: Thirty-six subjects (16 men and 20 women) received one or two dental implants in the anterior mandible, and all implants were loaded the day of surgery. Subjects were scheduled for follow-up 3-, 6-, and 12 months after implant placement and thereafter annually for 4 more years.
