Enamel - PowerPoint PPT Presentation


ENAMEL

Enamel, the hardest calcified tissue in the human body, forms a protective covering over the teeth, adapting them for mastication. Its thickness varies across different surfaces of the teeth, with maximum thickness found on cusps. The structure of enamel makes it brittle, especially when it loses su

Formation of Hertwig's Epithelial Root Sheath in Tooth Development

The formation of Hertwig's Epithelial Root Sheath (HERS) is crucial in determining the shape, length, and number of roots in teeth. It initiates the formation of radicular dentin, marking the beginning of root development after enamel and dentin formation. HERS consists of outer and inner enamel epi

Development Stages of Inner Enamel Epithelium

The life span of cells in the inner enamel epithelium can be divided into six stages: Morphogenic, Organizing, Formative, Maturative, Protective, and Desmolytic. Differentiation of ameloblasts occurs in various regions of the tooth germ. Amelogenesis, the enamel formation, takes place during the for

Root Development in Tooth Growth Process

Root formation plays a crucial role in the development of teeth, starting after enamel and dentin formation at the cementoenamel junction. Hertwig's epithelial root sheath (HERS) molds the shape of roots, initiating radicular dentin formation. The cervical loop forms an epithelial diaphragm, narrowi

Understanding Fluorosis: A Critical Health Concern in Endemic Regions

Fluorosis, a prevalent condition in parts of India, China, Tanzania, and South Africa, affects millions due to high fluoride levels in drinking water. It manifests as dental and skeletal fluorosis, causing various symptoms based on exposure levels. Dental fluorosis leads to enamel discoloration and

Understanding Enamel Pearl Anomaly in Dentistry

Enamel Pearl is a developmental anomaly where small nodules of enamel form below the cemento enamel junction, mainly on permanent teeth. This anomaly, detected radiographically, can lead to bacterial accumulation, periodontal issues, and inflammation if left untreated. Dental hygienists play a cruci

Mammalian Tooth Structure: Vertical Section Overview

Mammalian teeth consist of hard tissues (enamel, dentine, cementum) and soft tissue (tooth pulp). The enamel is the hardest, dentine surrounds the pulp cavity, and cementum covers the dentine and connects to the alveolar bone. Tooth pulp provides support, nourishment, and defense mechanisms. Support

Mammalian Dentition and Tooth Structure

Dentition refers to the arrangement of teeth in the upper and lower jaw of mammals. Most mammals have specialized teeth, with some exceptions like the Platypus and Baleen whales. The structure of a mammalian tooth includes the crown, root, and neck, made up of dentine, enamel, and cement. Tooth deve

Understanding Enamel Pearls and Fluorosis: Dental Abnormalities Explained

Enamel pearls are small spherical projections on root surfaces that can lead to plaque retention and gum disease if left untreated. They are caused by abnormal enamel formation during tooth development. On the other hand, fluorosis is marked by enamel hypomineralization due to excessive fluoride ing

Understanding Enamel: Structure, Formation, and Properties

Enamel is the hardest substance in the human body, formed by ameloblast cells during tooth development. Chemically, it consists mostly of inorganic matter, primarily hydroxyapatite. Mature enamel lacks organic matter, is avascular, and not renewed. Its structural unit is the enamel rod, surrounded b
