ABSTRACT
This article is a review of the principles and clinical guidelines for the new discipline of Microdentistry. It involves new concepts of early occlusal caries detection using new laser technology and relates to the non G. V. Black nature of the final cavity design. Newly discovered anatomical structures in teeth are discussed and why their conservation is important. New air-abrasion technology is used to cut the tooth, selectively removing damaged tooth structure, rather than the indiscriminate traditional manner of cutting the tooth with a high-speed bur. Microdentistry also relies on the use of adhesive glass-ionomer / composite restorative materials rather than amalgam. Consideration of patient caries risk factors, are also important in case selection and decisions on early intervention. In conclusion, it is hoped that by using early accurate diagnosis and minimal operative treatment, patients will retain their teeth in a cost effective manner
