Investigating relationships among strontium, barium, and seasonality in wild baboons

Archaeometry, EarlyView.
Abstract Geochemical profiles of Australopithecus africanus and baboon teeth show fluctuating trace elements, possibly reflecting seasonal diets. Here we use laser ablation–inductively coupled plasma–mass spectrometric measurements of calcium‐normalized strontium and barium ratios (Sr/Ca and Ba/Ca) and ion microprobe analyses of oxygen isotopes (δ18O ...

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.

Repeated Use of Emergency Departments for Nontraumatic Dental Conditions: Factors Associated With Being a Superutilizer

Community Dentistry and Oral Epidemiology, EarlyView.
ABSTRACT Background Due to inadequate access to regular, affordable dental care, many patients turn to emergency departments (EDs) for the treatment of nontraumatic dental conditions (NTDCs). NTDC ED visits are a large burden on the U.S. healthcare system, with over 1.3 million visits each year and over $1 billion in associated charges.

Effectiveness of Dentin Bonding Agents [PDF]

, 1989
The interface between a composite resin restoration and dentin is still a problem with regard to secondary caries and esthetics. With conventional restorative techniques the absence of bonding between the restorative material and the dentin produces ...

The Validity of ICD‐10 Codes in Recording the Incidence of Traumatic Dental Injuries

Dental Traumatology, EarlyView.
ABSTRACT Background/Aim Traumatic dental injuries (TDIs) significantly affect quality of life and healthcare costs. Large administrative datasets using ICD codes offer opportunities for epidemiological research; however, the accuracy of International Classification of Diseases, Tenth Revision (ICD‐10) codes for TDIs remains unclear. This study aimed to

Effect of silver diamine fluoride application on the microtensile bond strength of three commonly used restorative materials in primary teeth: An ultrastructural study

Journal of Indian Society of Pedodontics and Preventive Dentistry
Introduction: Caries in primary teeth rapidly advances owing to its thin structure, thereby requiring restoration. However, restorations often fail due to various causes such as secondary caries and reduced microtensile bond strength (μTBS), which calls ...

Dens Invaginatus as a Biomechanical Risk Modifier in Dental Trauma: Finite Element Analysis

Dental Traumatology, EarlyView.
ABSTRACT Introduction/Aims Traumatic dental injuries are common in childhood and may adversely affect functional and psychosocial well‐being. Dens invaginatus, a developmental anomaly caused by the infolding of the enamel organ during odontogenesis, alters tooth morphology and may influence biomechanical behavior under traumatic loading.

Dental pulp exposure, periapical inflammation and suppurative osteomyelitis of the jaws in juvenile Baltic grey seals (Halichoerus grypus grypus) from the late 19th century.

PLoS ONE, 2019
The systematic analysis of museum collections can provide important insights into the dental and skeletal pathology of wild mammals. Here we present a previously unreported type of dental defect and related skull pathology in five juvenile Baltic grey ...
