Dental Stigmata and Skeletal Lesions of Congenital Treponematosis in Early Agricultural Vietnam (4000–3500 bp)

International Journal of Osteoarchaeology, EarlyView.
ABSTRACT Prior research has documented treponematosis at a single site in Mainland Southeast Asia from northern Vietnam dated to the early agricultural transition (~4000–3500 bp). To date, no other cases in Southeast Asia's prehistory have been identified.

Trace Element Patterns in Juvenile Wild Chimpanzee Dentitions

Archaeometry, EarlyView.
ABSTRACT Trace elements are used to infer mammalian early‐life diets, environmental toxins, dispersal patterns, stress histories, and weaning ages. Here, we employ laser ablation‐inductively coupled plasma‐mass spectrometry (LA‐ICP‐MS) to reveal elemental patterns in our closest living relatives, chimpanzees.

Effects of Ozonized Oil on At‐Home Tooth Bleaching: A Double‐Blind Randomized Clinical Trial

Journal of Esthetic and Restorative Dentistry, EarlyView.
ABSTRACT Objective This double‐blind, randomized clinical trial evaluated the effect of ozonized sunflower oil on tooth sensitivity, color change, and patient perception during at‐home bleaching with 10% hydrogen peroxide. Clinical Considerations Forty participants were randomly assigned to receive ozonized or nonozonized sunflower oil, applied in ...
