Clinics and Practice, 2012 Enamel pearls are one of a number of different enamel structures that can be found on the roots of deciduous and permanent teeth. They have a distinct predilection for the furcation areas of molar, particularly the maxillary third and second molars. However, they have been found less commonly on the apical portions of the root.

Early stages of tooth development in the harbor porpoise Phocoena phocoena
The Anatomical Record, EarlyView.Abstract Here we describe the stages of tooth development in toothed whales on the basis of the harbor porpoise (Phocoena phocoena). The aim of the study was to find out whether these stages are identical to those of other mammals analyzed so far although toothed whales are homodont and monophyodont.

OBSERVATIONS ON STRUCTURAL FEATURES AND CHARACTERISTICS OF BIOLOGICAL APATITE CRYSTALS: 5. THREE-DIMENSIONAL OBSERVATION ON ULTRASTRUCTURE OF HUMAN ENAMEL CRYSTALS [PDF]
, 1993 In a series of studies to investigate the structural features of the biological crystals, such as the tooth and bone, using an electron microscope, we examined the ultrastructure of the enamel, dentin, and bone crystals at near atomic resolution and ...

Dental anomalies in Pleistocene African hippopotamuses from Olduvai Bed II
The Anatomical Record, EarlyView.Abstract Hippopotamuses are key palaeoenvironmental indicators in African Pleistocene ecosystems due to their ecological dependence on permanent water bodies and their frequent representation in the fossil record. This study examines dental anomalies in Hippopotamus cf. gorgops from several localities in Bed II of Olduvai Gorge (Tanzania), dated to ca.

The Anatomical Record, EarlyView.Abstract Hyperodapedontine rhynchosaurs possessed a unique oral apparatus, long interpreted as an adaptation for processing abrasive and resistant plant material. However, the microanatomical and histological evidence supporting this interpretation remains poorly documented.

BMEMat, EarlyView.Oral microbial homeostasis, a dynamic host‐microbe balance, is vital in infectious diseases. Conventional antibiotics often disrupt this homeostasis, spurring interest in nanomaterials for oral microbial homeostasis rebalancing. This review outlines nanomaterial strategies across three ecological levels (population/community, ecosystem, and cross ...
