Strain distribution within the tooth is related to its structure. Enamel acts as a stress distributor, transferring the load vertically to the root, and horizontally via the dentinoenamel junction (DEJ) to the dentin of the crown. A thick zone (~200 µm) in the dentin at the DEJ undergoes greater stress than the central coronal dentin. Recently discovered structures within the occlusal surface of molars 2,3 indicate that conventional cavity designs are disharmonious with the tooth's natural

This structure lies anterior to the predominant feature of the occlusal table of the maxillary first molars, the oblique or transverse ridge, and distal to the mesial marginal ridge.

This article discusses the concept of a "peripheral rim of enamel" and describes the manifestation of compressive and tensile fractures within the peripheral rim of enamel and dentin. It also emphasizes the benefits of microdentistry techniques and minimally invasive preparation designs in the long-term preservation of the natural tooth structure.

The structures and substructures of teeth have been generally misunderstood. Once these structures are understood, the goal of the microdentist is to identify unsound tooth structure, which is a threat to the long-term stability of the tooth, and then neutralize or remove those structures with minimal disruption of the surrounding sound tooth structure. Minimal disruption of sound tooth structure provides the additional patient benefit of reducing or eliminating the pain associated with traditional dentistry. This article reviews some of the newly discovered structures in human teeth and discusses methods of microdentistry used to preserve these structures.

Seventy two maxillary right and left first permanent molars of thirty-six patients were examined in this study. Horizontal linear measurements in millimeters, location, and shape of the occlusal ridge in the mesial fossa were examined clinically and were compared to the transverse ridge in a percentage form. Five occlusal enamel ridges with different locations, and pathways were detected in addition to the transverse ridge, two major ridges (> 33.33% of the transverse ridge) and three minor ridges (< 33.33%) of the transverse ridge). There were symmetrical patterns of the ridges between right and left maxillary first permanent molars (80.5%).

A predominant feature of this ridge as it underlies the anatomical landmark commonly referred to as the central "fossae," is its interconnection of the disto-lingual cusp and the mesio-buccal cusp. This ridge and other web structures found in enamel are important considerations when preparing teeth using ultra-conservative dentistry.

Thirty human lower permanent molars were examined in this study. The occlusal surface of each tooth was examined by explorer; a linear measurement in millimeters of carious lesions diagnosed in the pit, fissure and groove system was recorded. The same surface was then stained with caries detection dye. Linear measurements in millimeters were then recorded for areas of stain remaining in the pit, fissure, and groove system. The thirty teeth were then sectioned buccal lingually in three sections, exposing 180 saggital histological cross sections for histological examination. Histological cross section confirmed a ratio of 1:1 (100%) accuracy by caries detection dye in diagnosing decay underlying the occ...
