introdouction:tooth eruption is recognized as an important aspect of human growth and development. it can be influenced by a number of factors, and it may reflect the general development of a child’s body. the purpose of this study was to determine the age at which the first primary tooth erupted and its relationship with height, weight and head circumference in 3-15-month children in the city ...

Specific stem cell populations within dental mesenchymal tissues guarantee tooth homeostasis and regeneration throughout life. The decision between renewal differentiation of cells is greatly influenced by interactions with stromal extracellular matrix molecules that form the tissue specific niches. Cxcl12 chemokine a general marker plays fundamental roles in maintenance, mobilization migration...

Regenerative medicine and tissue engineering technologies have greatly benefitted medicine and dentistry over the past years (Zaky & Cancedda 2009). The use of protein-, geneand stem cell-based therapeutics have been exploited significantly in the reconstruction of new tissues and organs (Discher et al. 2009). The field of oral and periodontal regenerative medicine has undergone significant rec...

Introduction Regenerating a tooth completely in human oral cavity is not achieved by current studies yet. Here, we have conceived a man-induced method to construct a teeth germ which might be used to regenerate a tooth in vivo. This idea was generated by traits of the development of the compound odontoma, a benign tumour of tooth malformation. This is a kind of developmental tooth malformation,...

PURPOSE Damage to the inferior alveolar nerve when extracting lower third molars is often caused by the intimate relationship between the nerve and the roots of the teeth. The technique of coronectomy, or intentional root retention, may minimize this problem. PATIENTS AND METHODS Forty-one patients underwent coronectomy on 50 lower third molars with follow-up of at least 6 months. The techniq...

abstract the attrition of anterior teeth leads to the loss of efficient anterior guidance, which protects posterior teeth from wear during lateral excursions. this clinical report describes a 48-year-old man with diagonal tooth wear and posterior mandibular tooth loss. the clinical diagnosis was based on a complete oral examination, photos, functional analysis of lateral excursion movements, ge...

Just as modern nation-states struggle to manage the cultural and economic impacts of migration, ancient civilizations dealt with similar external pressures and set policies to regulate people's movements. In one of the earliest urban societies, the Indus Civilization, mechanisms linking city populations to hinterland groups remain enigmatic in the absence of written documents. However, isotopic...

The tooth is an ectodermal organ that arises from a tooth germ under the regulation of reciprocal epithelial-mesenchymal interactions. Tooth morphogenesis occurs in the tooth-forming field as a result of reaction-diffusion waves of specific gene expression patterns. Here, we developed a novel mechanical ligation method for splitting tooth germs to artificially regulate the molecules that contro...

Impairments in cell migration processes may cause various diseases, among which cancer cell metastasis, tumor angiogenesis, and the disability of immune cells to infiltrate into tumors are prominent ones. Mathematical modeling has been widely used to analyze the cell migration process. Cell migration is a complicated process and requires statistical methods such as random walk for proper analys...
