Different animal models have been introduced recently to study the process of reparative dentinogenesis in response to injury-induced pulp exposure. Using a mouse model is advantageous over other animal models since mice can be genetically manipulated to examine specific cellular pathways and lineage trace the progeny of a single cell. However, enabling a standardized molar damage in mice is demanding due to the small size of the teeth compared to the available dental instruments. Here we describe a reproducible and reliable in vivo model that allows us to study dentinogenesis in the first maxillary mouse molar.

UI	MeSH Term	Description	Entries
D008963	Molar	The most posterior teeth on either side of the jaw, totaling eight in the deciduous dentition (2 on each side, upper and lower), and usually 12 in the permanent dentition (three on each side, upper and lower). They are grinding teeth, having large crowns and broad chewing surfaces. (Jablonski, Dictionary of Dentistry, 1992, p821)	Molars
D003810	Dentinogenesis	The formation of dentin. Dentin first appears in the layer between the ameloblasts and odontoblasts and becomes calcified immediately. Formation progresses from the tip of the papilla over its slope to form a calcified cap becoming thicker by the apposition of new layers pulpward. A layer of uncalcified dentin intervenes between the calcified tissue and the odontoblast and its processes. (From Jablonski, Dictionary of Dentistry, 1992)	Dentinogeneses
D000078483	Regenerative Endodontics	A dental specialty concerned with biologically-based procedures designed to physiologically replace damaged tooth structures, including dentin and root structures, as well as cells of the pulp-dentin complex.

D000818	Animals	Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.
