Disturbances and defects in enamel development.

J W Simmelink, V K Nygaard

Journal of Dental Research

|March 1, 1979

Summary

This summary is machine-generated.

Experimental disturbances like tetracyclines and fluorides disrupt enamel formation. Cellular changes impair matrix production and secretion, leading to abnormal crystal structure in developing enamel.

Background:

Ameloblastic disturbances are linked to enamel defects.
Enamel formation is a complex biological process.
Factors like tetracyclines, fluorides, and antimitotic drugs can experimentally induce enamel disturbances.

Purpose of the Study:

To review experimental disturbances in amelogenesis.
To highlight cellular alterations affecting enamel matrix.
To identify key areas for future research in enamel development.

Main Methods:

Review of experimental studies on enamel formation.
Analysis of cellular mechanisms involved in amelogenesis.
Examination of defects in enamel crystal structure.

Main Results:

Cellular alterations interfere with enamel matrix production and secretion.
Enamel defects are characterized by abnormal crystal size and distribution.
Experimental agents like tetracyclines and fluorides cause specific cellular and matrix alterations.

Conclusions:

Understanding ameloblast function is crucial for normal enamel development.
Further research is needed on matrix secretion, crystal nucleation, and mineralization.
Investigating the roles of the stratum intermedium and papillary layer is essential for understanding maturation.
