Long-term follow-up and tomographic assessment of an intrabony defect treated with enamel matrix derivative.

Background: Enamel matrix derivative (EMD) has an extensive documentation of use in the treatment of periodontal defects. Digital volume tomography (DVT) has been in use in dental medicine since the late 1990s, with a major advantage of decreased radiation and cost-effectiveness compared to conventional computed tomography (CT). To the best of our knowledge, there is no peer-reviewed report documenting long-term tomographic assessment of an intrabony defect treated with EMD alone.

Effect of abutment angulation on the strain on the bone around an implant in the anterior maxilla: a finite element study.

Statement Of Problem: Angled abutments are often used to restore dental implants placed in the anterior maxilla due to esthetic or spatial needs. The effect of abutment angulation on bone strain is unknown.

Purpose: The purpose of the current study was to measure and compare the strain distribution on the bone around an implant in the anterior maxilla using 2 different abutments by means of finite element analysis.

Learning to smile: the neuroanatomic basis for smile training.

Unlabelled: This article demonstrates that although any layperson could recognize that the smile manifests mainly in the oral and periorbital regions, a comprehension of the neurologic and musculoskeletal elements lends the clinician insight into the many aspects of a smile. The neurologic control of a smile consists of a complex process involving many facets. As with any other complex neuromuscular activity, repetitions of the act can train the central nervous system, neural network, and muscular network in efficient performance of and correct musculoskeletal activation involved in the act itself.

Forensic dental identifications in the greater Houston area.

In order to confirm the identity of the deceased, 1.7% of the deaths (162 cases) evaluated at the Harris County Medical Examiner's Office during the time period of this study required a forensic dental evaluation. Data were collected and analyzed.
