The Late-Cretaceous appearance of grasses, followed by the Cenozoic advancement of grasslands as dominant biomes, has contributed to the evolution of a range of specialized herbivores adapted to new diets, as well as to increasingly open and arid habitats. Many mammals including ruminants, the most diversified ungulate suborder, evolved high-crowned (hypsodont) teeth as an adaptation to tooth-wearing diets and habitats. The impact of different causes of tooth wear is still a matter of debate, and the temporal pattern of hypsodonty evolution in relation to the evolution of grasslands remains unclear...

BACKGROUND: Nicolaides-Baraitser Syndrome(NCBRS) is an extremely rare condition which has been reported in only a few cases. NCBRS is a distinct clinical condition with typical clinical features of pre- and post-natal global developmental delay, impaired speech, and seizures. Microcephaly, sparse hair, anteverted alae nasi, undefined philtrum, prominence of distal phalanges and interphalangeal joints, and short metacarpals are also typical of NCBRS. CASE REPORT: There are no reported cases in the literature of patients with NCBRS presenting with multiple dental impactions, and to the authors' knowledge, this is the 28th fully documented case of NCBRS and only 75 cases identified as potentially having NCBRS...

Primary cilium is a solitary organelle that emanates from the surface of most postmitotic mammalian cells and serves as a sensory organelle, transmitting the mechanical and chemical cues to the cell. Primary cilia are key coordinators of various signaling pathways during development and maintenance of tissue homeostasis. The emerging evidence implicates primary cilia function in tooth development. Primary cilia are located in the dental epithelium and mesenchyme at early stages of tooth development and later during cell differentiation and production of hard tissues...

INTRODUCTION: Root resorptions are, with white spots, some of the inconveniences caused by orthodontic treatments. Although they are rare, they should not be ignored despite the many benefits gained by orthodontic treatment. Contrary to white spots, which are controllable by good dental hygiene, root resorptions can occur despite patient cooperation. Orthodontists should be aware of this phenomenon and make regular radiologic controls a priority for detection "before, during and after" treatment...

Lamniform sharks are apex marine predators undergoing dramatic local and regional decline worldwide, with consequences for marine ecosystems that are difficult to predict. Through their long history, lamniform sharks have faced widespread extinction, and understanding those 'natural experiments' may help constrain predictions, placing the current crisis in evolutionary context. Here we show, using novel morphometric analyses of fossil shark teeth, that the end-Cretaceous extinction of many sharks had major ecological consequences...

OBJECTIVE: To investigate racial differences in the associations between periodontitis and 10-year self-reported incident tooth loss in a biracial, community-based cohort of US late middle-aged and older adults. METHODS: Subjects were 3,466 dentate men and women aged 53-74 who underwent dental examinations from 1996 to1998. In 2012-2013, telephone interviewers asked participants about tooth loss in the preceding 10 years. Separate multivariable ordinal logistic regression models were used to calculate proportional odds ratios (OR) and 95% confidence intervals (CI) as estimates of association between periodontitis and tooth loss for Whites and African-Americans (AAs)...

BACKGROUND: Caries in second molar is common and prophylactic removal of the impacted teeth may be considered appropriate. Caries detection and restoration can be difficult and a restored second molar can undergo recurrent caries if the third molar is not removed prophylactically. In this study, the clinical findings related to impaction and its association with angular position and depth of impacted third molar were evaluated. MATERIALS AND METHODS: A retrospective descriptive study was carried out among the patients visiting the outpatient, department of Dentistry, RIMS, Ranchi...

BACKGROUND: With increasing numbers of people surviving beyond eighty years, this section of the population demands attention to reduce the impact of dementia. In order to develop effective preventative strategies, it is essential to understand age-specific risk factor profiles for dementia: do risk factors for dementia in those in their sixties and seventies persist into oldest age? The aims of this study were to determine incident dementia and to investigate the risk profile for dementia from age 79 to 95 years in a well-characterised cohort...

INTRODUCTION: Injuries concerning the skull, the mouth and thus potentially involving the mouth and teeth are characterized as major public health problems due to their high prevalence and very serious functional and aesthetic consequences. Pain, aesthetic and functional problems arising from dental trauma significantly disrupt normal function, and impact, often dramatically, on young patients' quality of life. PROCEDURE: With regards to the behavior management approach to a child who has suffered a dental trauma, dentist's first step is to be to reassure child and parents...
