Effects of Calcium Hydroxide Paste and Access Cavities on Fracture Strength of Mature and Simulated Immature Human Teeth: Ex Vivo

Australian Endodontic Journal, EarlyView.
ABSTRACT The aim was to examine whether a Ca(OH)2 paste affects fracture strength of teeth. Sixty extracted maxillary central incisors were prepared to simulate immature teeth. Another 40 were used as mature teeth. The ten groups (n = 10) were: (1) immature control; (2) immature + access; (3) immature + access + 1 m Ca(OH)2; (4) immature + access + 12 ...

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.

Cementum analysis in cleidocranial dysostosis

Indian Journal of Dental Research, 2008
Cleidocranial dysostosis (CCD) is a skeletal disorder associated with dental anomalies such as failure or delayed eruption of permanent teeth and multiple impacted supernumerary or permanent teeth. Absence of cellular cementum at the root apex is presumed to be one of the factors for failure or delayed eruption. The aim of this study was to analyze the

Ecological variability of Hippopotamus antiquus from the late Early–Middle Pleistocene of Megalopolis Basin (Greece): Evidence for dynamic habitats in a glacial microrefugium

Boreas, EarlyView.
This study investigates the ecology of the extinct European Hippopotamus from the late Early–Middle Pleistocene (c. 900–400 ka) sequence of the Megalopolis Basin, a glacial microrefugium for temperate taxa in southern Greece. Using stable carbon (δ13C) and oxygen (δ18O) isotope analyses and microwear analyses of Hippopotamus dental elements, we ...

Isolation of Protein-Tyrosine Phosphatase-like Member-a Variant from Cementum

, 2011
Cementum has been shown to contain unique polypeptides that participate in cell recruitment and differentiation during cementum formation. We report the isolation of a cDNA variant for protein-tyrosine phosphatase-like (proline instead of catalytic ...

Prognosis of Traumatized Permanent Teeth Affected by Multiple Injuries (Combination Injuries): A Systematic Review and Meta‐Analysis

Dental Traumatology, EarlyView.
ABSTRACT Background/Aims The prognosis of traumatic dental injuries (TDI) of permanent teeth depends on several factors related to the injury, patient characteristics, management, and follow‐up protocols. When such injuries affect both hard dental tissues and the periodontium (“combination injuries”), the risk of adverse healing complications increases.

Descriptive Evaluation of Medium‐ and Long‐Term Complications of Traumatic Dental Injuries in Children and Adolescents Reporting to a Tertiary Care Hospital

Dental Traumatology, EarlyView.
ABSTRACT Background/Aims Traumatic dental injuries (TDIs) frequently present with acute symptoms, yet many adverse outcomes manifest months or years later as medium‐ and long‐term consequences. These sequelae, such as pulp necrosis with infection of root canal system, periapical radiolucency, and external inflammatory resorption, pose significant ...

Traumatic Dental Injuries as a Potential Predisposing Factor for Invasive Cervical Resorption: A Systematic Review

Dental Traumatology, EarlyView.
ABSTRACT Invasive cervical resorption is a clinically challenging and often silent form of external root resorption that may remain undetected until substantial structural damage has occurred. Although traumatic dental injuries are repeatedly cited as potential predisposing factors, the strength, consistency, and clinical meaning of this association ...
