Affect intensity and cardiac arousal.

Investigated in 3 experiments the relationships between affect intensity and basal, evoked, and perceived cardiac arousal. Affect intensity was assessed using R. J. Larsen and E. Diener's (1987) Affect Intensity Measure (AIM). Cardiac arousal was evoked with exercise in the 1st study and with mental arithmetic in the 2nd and 3rd. Perceived cardiac arousal was measured under optimal conditions using a standard heartbeat discrimination procedure. Women as a group scored higher on the AIM. Affect intensity was unrelated to basal or evoked cardiac arousal and was negatively related to perceived cardiac arousal in all 3 studies. Data suggest that affect intensity, although unrelated to actual physiological arousal, is negatively related to the accuracy with which individuals perceive their own arousal. Results are discussed within the context of an expanded arousal-regulation model (J. Blascovich, 1990). (PsycINFO Database Record (c) 2010 APA, all rights reserved)

Diagnosis and treatment planning for implant dentistry

Dental implants are well-established in dentistry and allow the restorative dentist to offer patients the best that dentistry has to offer. Through examination, radiographs, and study models, the restorative dentist and implant surgeon can develop a treatment plan. Comprehensive diagnosis and treatment planning involve much more than a clinical exam--they require an investigation involving past, present and future dental therapy.
