Human age estimation from tooth cementum and dentin.

Journal of clinical and diagnostic research : JCDR, 2014
BACKGROUND Age estimation is an important factor in the identification of an individual in forensic science. The hard tissues of the human dentition are able to resist decay and degradation, long after other tissues are lost.

Geological Substrate Is Related to Tooth Senescence and Population Dynamic: The Case Study of Alpine Chamois (Rupicapra rupicapra L.)

Integrative Zoology, EarlyView.
In Alpine chamois, the complete wear of the first molar coincides with the beginning of senescence and the progress of tooth wear on calcareous substrate is slower than the one on other substrates, increasing life expectancy. Thus, the first molar wear may actually be considered as an effective descriptor of senescence stage.

Serum, Saliva, and Gingival Crevicular Fluid Osteocalcin: Their Relation to Periodontal Status and Bone Mineral Density in Postmenopausal Women [PDF]

, 2005
Background: Periodontitis and osteoporosis are characterized by the loss of bone mass. Osteocalcin levels have been postulated as a marker of inhibition of bone formation.

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.

Histopathological evaluation of different methods of experimental induction of periapical periodontitis [PDF]

, 2008
This study evaluated histopathologically different methods of experimental induction of periapical periodontitis. The radiographic and microbiological evaluations have been performed in a previous investigation.

Association of Maxillofacial Fractures With Demographic and Dental Factors: The Roles of Edentulism, Posterior Occlusion, Canines, and Lower Third Molar

Dental Traumatology, EarlyView.
ABSTRACT Background/Aim This retrospective, two‐center study aims to improve understanding of fracture pathogenesis in maxillofacial trauma by examining variations related to sex, age, dental status, posterior occlusion, and the presence of lower third molars (LTM) and lower canines.

Alteration in oral and non‐oral tissues in ligature‐induced periodontitis mice with the Alzheimer's disease risk factor APOE4

European Journal of Oral Sciences, EarlyView.
Abstract The APOE4 gene, particularly the ε4 allele, is linked to susceptibility to Alzheimer's disease, and periodontitis can cause pathological changes in multiple organs, but combined effects of these conditions and the impact of tumor necrosis factor (TNF)‐α regulation on the combined effects remain unclear.

Prevalence of peripheral dental caries and diastemata in horses fed high‐carbohydrate diets

Equine Veterinary Education, EarlyView.
Summary Background Peripheral dental caries and diastemata impair equine oral health. Diets rich in soluble carbohydrates are suspected risk factors, but few studies have assessed their impact. In Brazil, sugarcane is widely used as a forage source due to its availability and low cost.

Incremental lines in root cementum of human teeth: An approach to their role in age estimation using polarizing microscopy

Indian Journal of Dental Research, 2008
Age estimation is an important factor in the identification of an individual in forensic science. The hard tissues of the human dentition are able to resist decay and degradation long after other tissues are lost.

Microhardness of nonfluorosed and fluorosed dental cementum: An in vitro study

SRM Journal of Research in Dental Sciences, 2017
Aim: The literature on the effect of fluoride on dental caries is well discussed in contrast to periodontal tissues. However, a recent review has explored an epidemiological association between fluorosis and periodontal disease and also the influence of ...
