Critical Reviews in Oral Biology & Medicine, 1993
The formation of dentin, dentinogenesis, comprises a sophisticated interplay between several factors in the tissue, cellular as well as extracellular. Dentin may be regarded as a calcified connective tissue. In this respect, as well as in its mode of formation, it is closely related to bone.

Uninherited dentinogenesis imperfecta
Oral Surgery, Oral Medicine, Oral Pathology, 1975The rare hereditary disease, dentinogenesis imperfecta, is a disturbance of dentin formation in both the deciduous and permanent dentitions. It may be associated with osteogenesis imperfecta, though it is probably that the two diseases are carried by different genes. This association was recognized in a 19-year-old man.

Trauma and Dentinogenesis: A Case Report
Journal of Endodontics, 2010After a traumatic injury to the upper central incisors of a 7-year-old patient, avulsion of tooth #9 and pulp exposure after crown fracture of tooth #8 were managed.After immediate replacement of tooth #9 in its socket, teeth were splinted for 3 weeks.

Possible mechanisms of induction of dentinogenesis
Medical Hypotheses, 1984The following hypothesis is proposed: The inner enamel epithelium influences all cells of the dental papilla very early during embryologic development--long before any morphologic changes due to histo-differentiation are noticeable. During normal odontogenesis, the epithelium acts as a second order inducer for the differentiation of odontoblasts and ...

Histochemical study of amelogenesis and dentinogenesis
Oral Surgery, Oral Medicine, Oral Pathology, 1957Summary Based on the studies of Wislocki and co-workers, 31, 32 and of Todescan and Sasso, 30 we present a histochemical study on the existence of alkaline phosphatase, acid mucopolysaccharides, keratin, and calcium, and correlate the substances under study with the mechanism of the elaboration of the organic matrix and its consequent ...

Dentin Matrix Proteins and Dentinogenesis
Connective Tissue Research, 1995The precise mechanisms involved in dentinogenesis are not understood; however, the information to date suggests that a number of highly controlled extracellular events are involved. Mature odontoblasts secrete collagen at the cell border into predentin.

Dentinogenesis imperfecta with dens in dente
Oral Surgery, Oral Medicine, Oral Pathology, 1983An uncommon case of dentinogenesis imperfecta with dens in dente was studied by light microscopy, microradiography, and electron-microprobe analysis. Numerous canals and cellular inclusions were found in the coronal portion of the dentin where the tubules were sparse and irregularly distributed.

The Inorganic Phase in Dentinogenesis imperfecta
Journal of Dental Research, 1981High resolution TEM, X-ray diffraction analysis, infrared absorption spectroscopy, thermogravimetry, and chemical and electron microprobe analyses showed that in dentinogenesis imperfecta the mineral phase is a carbonated apatite with crystallites of normal size, but less numerous than in normal dentin. Losses of Ca, P, and Mg, and a higher Ca/P ratio

Dentinogenesis imperfecta. A new perspective
Australian Dental Journal, 1985Abstract— ‐Recent knowledge of collagen biochemistry has increased dramatically with current concepts of its biosynthesis and structure, strengthening the belief that osteogenesis imperfecta and dentinogenesis imperfecta syndromes are basically molecular collagen defects of Type I collagen.The information presently available from studies on dentine ...
