Changes in the Location of the Second Mesiobuccal Canal Orifice After Canal Preparation in Maxillary First Molars

Australian Endodontic Journal, EarlyView.
ABSTRACT This study evaluated angular and linear positional changes of the second mesiobuccal (MB2) canal orifice in maxillary first molars and proposed a guideline for its localization. Twenty‐eight extracted maxillary first molars with four canals were analysed. After access cavity preparation, all canals except MB2 were instrumented. The initial and

In-Vitro Comparison of The Validity and Reproducibility of Laser Fluorescence and Electrical Method in the Diagnosis of Initial Occlusal Caries

Van Tıp Dergisi, 2019
INTRODUCTION: Diagnosis of early occlusal caries lesions allows treatment with preventive treatments or minimally invasive approaches. For this reason, new caries diagnostic methods using laser fluorescence and electrical systems have been developed as ...

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.

Proteomic Sex Estimation From Embedded Tooth Enamel

Archaeometry, EarlyView.
ABSTRACT Teeth hold insights into childhood diet, health and demography—including chromosomal sex. Proteomic analysis can detect peptide biomarkers from amelogenin genes encoded on X and Y chromosomes, allowing sex estimation. Embedding resins, necessary for thin sectioning teeth, can damage analytical systems, preventing proteomic analysis. We present

In vitro comparison of Nyvad's system and ICDAS-II with lesion activity assessment for evaluation of severity and activity of occlusal caries lesions in primary teeth

, 2009
This in vitro study of occlusal surfaces on primary molars aimed to: (1) evaluate the reproducibility of the Nyvad and ICDAS-II visual systems in detecting caries; (2) to test the accuracy of the systems in estimating lesion depth, and (3) to examine the

Can a Low‐Threshold Check‐Up Motivate Older Adults to Schedule a Dental Visit? A Randomized Controlled Trial

Community Dentistry and Oral Epidemiology, EarlyView.
ABSTRACT Objectives Oral disorders are an important disability driver in adults aged 70 and older, who often experience greater tooth loss and higher levels of untreated oral disease than younger persons. Despite the importance of regular dental visits, older adults attend dental services less frequently, facing several barriers.
