Diversity and random forest models of oral microbiomes in periodontal health using publicly available data

Journal of Periodontology, EarlyView.
Abstract Background Evidence on the 16S metabarcoding of supragingival, subgingival, and salivary microbiomes in periodontal health remains limited. We aimed to analyze the diversity and potential of machine‐learning models of supragingival, subgingival, and salivary microbiomes in periodontal health. Methods A total of 848 samples (supragingival = 210;

An aminostratigraphy of the northern Upper Rhine Graben, Germany

Journal of Quaternary Science, EarlyView.
ABSTRACT The northern Upper Rhine Graben (Germany) contains a complex, quasi‐continuous Quaternary record, but constraining its chronology is challenging. This study presents the first application of amino acid geochronology for this region using Bithynia opercula to establish a relative dating framework.

Hominin and carnivore roles during the formation of the early Middle Pleistocene site of Loreto (Venosa Basin, southern Italy)

Journal of Quaternary Science, EarlyView.
ABSTRACT The site of Loreto (Venosa Basin, Italy) was first discovered in 1929 and subsequently excavated during the latter half of the 20th century. The excavation revealed three archaeo‐palaeontological levels, with the lowermost level (Level A) yielding the largest number of remains.

Minor Traumatic Injuries to the Permanent Dentition [PDF]

Dental Clinics of North America, 2009
Treatment of traumatized teeth generally occurs in two phases: short-term emergency treatment and stabilization followed by endodontic management and review. These authors recently reviewed the endodontic considerations in the treatment of traumatized permanent anterior teeth, and in this article review the early management of traumatized permanent ...

Studies on agenesis in the permanent dentition

American Journal of Physical Anthropology, 1971
AbstractTooth dimensions in 104 males and females with agenesis of one or more permanent teeth, other than third molars, have been examined. The amounts of size reduction from normal in mesiodistal and buccolingual tooth diameters appear to be independent. Also some apparent differences from normal tooth size variability were noted.
