A forensic dental determination of serial killings by three African lions.

Forensic dentistry's role in solving homicide cases is not limited to victim and other human identifications. This science also can apply to perpetrators, human as well as animal, and can clarify historical incidents that occurred many years ago. In two cases more than 90 years apart, three African lions were jointly responsible for the killing of 141 humans for food, replacing their normal animal prey. A thorough dental analysis identified pathologies that may have forced the cats to select slower and less troublesome prey (humans) over their traditional food sources. The uncanny ability of these lions to avoid traps, ambushes, and gunfire while they continued to prey on so many well-armed and forewarned men remains unexplained.

The evolution of human occlusion--ancient clinical tips for modern dentists.

Man evolved in an environment in which the occlusion was worn down quickly, resulting in flattened occlusal and interproximal surfaces. This rapid wear reduced occlusal decay, traumatic occlusion, malaligned teeth, impactions, and temporomandibular disease (TMD). In the last 250 years, however, new food production techniques created an environment that was less dentally abrasive than earlier diets. Teeth were not worn down as programmed in our "evolutionary blue-print." This lack of wear resulted in increased caries, cusp fractures, bruxing, malocclusion, periodontal disease, and TMD. A practical re-creation of ancient dental wear patterns can help to reduce these modern dental diseases.

Hazards of gloves in dentistry.

Concerns about AIDS, hepatitis and infection control have increased the use of gloves in medical and dental practice. Though generally assumed to be protective, gloves pose many hazards to the practitioner and patient. This is especially significant in dentistry where a large assortment of materials and manipulative techniques are used as part of treatment. Gloves, with relatively large porosities, are poor barriers to viruses. They can promote bacterial growth, skin lesions, toxic and allergic reactions in patient and staff. Gloves are costly, time consuming to use, reduce sensitivity and dexterity. Gloves do not protect the wearer from penetrating injuries, the leading source of HIV and HBV infections in health care workers. The use of gloves is helpful only in those cases where their advantages outweigh liabilities. Governmental regulations, requiring universal glove-wear compliance, may not be in the best public or professional interest.

Accelerated healing of gingival incisions by the helium-neon diode laser: a preliminary study.

Fifty-two extraction patients had one of two gingival flap incisions lased with a helium-neon (He-Ne) diode laser at a fluence (energy density) of 1.2 J/cm. The rate of relative healing was evaluated clinically and photographically. Seventy-nine percent of the lased incisions healed more quickly than did the control incisions. No significant difference in healing was noted when patients were compared by age, gender, race, or anatomic location of the incision. This study suggests that He-Ne diode lasers, at the above energy level, appear to increase the rate of gingival wound healing in humans, without negative side effects.
