It consists of three regions: free gingiva, attached gingiva and interdental gingiva. It is composed of stratified squamous epithelium and dense connective tissue. It has a keratinized or parakeratinized surface layer that protects it from mechanical and chemical trauma. It has a basal lamina that attaches it to the underlying connective tissue. It has rete pegs and connective tissue papillae that interlock with each other and increase the surface area for adhesion. It has a gingival sulcus that is a narrow space between the free gingiva and the tooth surface. It has a junctional epithelium that is a specialized epithelium that attaches the gingiva to the tooth surface by hemidesmosomes and forms a seal against bacterial invasion. - Tongue: The muscular organ that occupies the floor of the mouth and performs functions such as mastication, deglutition, taste and speech. It consists of four regions: tip, blade, body and root. It is composed of skeletal muscle fibers and stratified squamous epithelium. It has a keratinized or parakeratinized surface layer that protects it from mechanical and chemical trauma. It has a basal lamina that attaches it to the underlying muscle tissue. It has papillae that are projections of the epithelium and/or connective tissue that increase the surface area for taste and friction. It has taste buds that are specialized sensory structures that detect different types of tastes. It has lingual glands that are minor salivary glands that secrete saliva to moisten and lubricate the tongue. - Salivary glands: The exocrine glands that secrete saliva into the oral cavity to perform functions such as digestion, lubrication, protection and buffering. They consist of three pairs of major salivary glands: parotid, submandibular and sublingual glands; and numerous minor salivary glands scattered throughout the oral mucosa. They are composed of acini (secretory units) and ducts (conduits). They have two types of acini: serous acini that secrete a watery fluid rich in enzymes; and mucous acini that secrete a viscous fluid rich in mucins. They have two types of ducts: intercalated ducts that connect the acini to the striated ducts; and striated ducts that modify the saliva composition by reabsorbing sodium and chloride ions and secreting potassium and bicarbonate ions. They have a capsule that surrounds the gland and divides it into lobes and lobules. They have a stroma that supports the glandular tissue and contains blood vessels, nerves and lymphatics. - Oral mucosa: The lining of the oral cavity that covers the lips, cheeks, palate, floor of the mouth, alveolar ridges, tonsils and oropharynx. It consists of three types: lining mucosa, masticatory mucosa and specialized mucosa. It is composed of stratified squamous epithelium and loose connective tissue (lamina propria). It has a non-keratinized or keratinized surface layer depending on the location and function. It has a basal lamina that attaches it to the underlying connective tissue. It has rete pegs and connective tissue papillae that interlock with each other and increase the surface area for adhesion. It has minor salivary glands that secrete saliva to moisten and lubricate the oral mucosa. It has sensory receptors that detect touch, pain, temperature and taste. ## Dental Embryology Dental embryology is the study of the development and eruption of teeth and oral tissues.

and the dental papilla differentiates into two layers: outer layer of cells (future odontoblasts) and inner core of cells (future pulp) - Apposition: The stage that occurs from the 4th month of intrauterine life to several years after birth, when the enamel, dentin, cementum and pulp are formed by the secretion of matrix from the inner enamel epithelium, outer layer of dental papilla, cementoblasts and pulp cells respectively - Maturation: The stage that occurs simultaneously with apposition, when the matrix of enamel, dentin, cementum and pulp is mineralized by hydroxyapatite crystals - Eruption: The stage that occurs from 6 months to 21 years after birth, when the teeth move from their developmental position within the jaw bone to their functional position in the oral cavity The involvement of dental lamina, dental organ, dental papilla and dental sac in tooth formation include: - Dental lamina: A band of oral epithelium that gives rise to the enamel organ of deciduous teeth and permanent molars, as well as to the successional lamina that gives rise to the enamel organ of permanent incisors, canines and premolars - Enamel organ: A cap-shaped structure derived from oral epithelium that forms the enamel of a tooth by differentiating into ameloblasts - Dental papilla: A mass of mesenchyme that gives rise to the dentin and pulp of a tooth by differentiating into odontoblasts and pulp cells - Dental sac: A mass of mesenchyme that gives rise to the cementum, periodontal ligament and alveolar bone of a tooth by differentiating into cementoblasts, fibroblasts and osteoblasts The common anomalies and defects of tooth development include: - Anodontia: The complete absence of teeth due to failure of initiation - Hypodontia: The partial absence of teeth due to failure of initiation - Supernumerary teeth: The presence of extra teeth due to excessive initiation - Microdontia: The abnormally small size of teeth due to defective apposition or maturation - Macrodontia: The abnormally large size of teeth due to excessive apposition or maturation - Gemination: The formation of two incomplete teeth from one tooth bud due to incomplete division - Fusion: The union of two adjacent teeth from two separate tooth buds due to contact and fusion - Concrescence: The union of two adjacent teeth by cementum only due to contact and fusion - Dilaceration: The abnormal bending or distortion of a tooth root or crown due to trauma or pressure - Dens invaginatus: The infolding of the enamel organ into the dental papilla during development, resulting in a tooth with an invagination or a deep pit - Dens evaginatus: The outgrowth of the enamel organ from the dental papilla during development, resulting in a tooth with an evagination or a tubercle - Enamel hypoplasia: The defective formation of enamel due to disturbances in amelogenesis, resulting in a tooth with thin, pitted or grooved enamel - Enamel hypocalcification: The defective mineralization of enamel due to disturbances in maturation, resulting in a tooth with chalky, soft or discolored enamel - Dentin dysplasia: The abnormal development of dentin due to disturbances in dentinogenesis, resulting in a tooth with abnormal root shape, pulp size or dentin structure - Dentinogenesis imperfecta: A hereditary disorder of dentin formation that affects both deciduous and permanent teeth, resulting in teeth with opalescent dentin, bulbous crowns, obliterated pulp chambers and root canals, and increased susceptibility to wear and fracture - Dentinal hypersensitivity: The increased sensitivity of dentin to stimuli such as temperature, pressure or chemicals due to exposure of dentinal tubules by enamel loss, gingival recession or root abrasion - Pulpitis: The inflammation of the pulp due to bacterial infection, trauma or irritation, resulting in pain and pulp necrosis - Pulp polyp: The overgrowth of granulation tissue from an exposed pulp due to chronic pulpitis, resulting in a red or pink mass protruding from the pulp chamber - Root resorption: The loss of cementum and dentin from the root surface due to pressure, infection or inflammation, resulting in shortening or deformation of the root - Ankylosis: The fusion of cementum and alveolar bone due to loss of periodontal ligament, resulting in immobility and infraocclusion of the tooth ## Books PDF File Books pdf file are electronic versions of printed books that you can access and download online.
