The sulcular epithelium is similar to the outer gingival. The mean width of attached gingiva increases from the primary dentition to permanent dentition 23. They contain nuclei with clefts, lysosomes, centrioles, Golgi vesicles, a small amount of endoplasmic reticulum, and moderate numbers of mitochondria. Due to infiltration by the immune cells, there is a loss of desmosomal attachment and widening of the intercellular spaces 96, 97. The melanin pigmentation of the gingiva is normally observed in individuals of African, East-Asian or Hispanic ethnicity 77. It has been demonstrated that pathogen-associated molecular patterns (PAMPs), shared by many different periodontopathogenic bacteria, stimulate the resident gingival epithelial cells to initiate inflammatory responses in a TLR-dependent manner 69. Along with acting as a physical barrier, the gingival epithelium also plays an important role in the innate immune response 61. The gingiva is palpated with a blunt instrument to check for its consistency. Abstract: The texture of the gingival surface may be similar to orange peel and is referred to gingival stippling. The dendritic cells in the epithelium are known as Langerhan’s cells. These serve as “sentinels” of the oral mucosa and inform the immune system not only about the entry of the pathogen, but also about the tolerance to self antigens and commensal microbes. It is usually given its due importance when the gingival … Save my name, email, and website in this browser for the next time I comment. Because it represents the area of fusion of junctional epithelium of two adjoining teeth, it is non-keratinized and is more susceptible to damage from plaque and other noxious stimuli as compared to the keratinized gingiva. Morphologically, they become more flattened as they move from basal layer towards the surface. • In 40% of adults Gingiva show stippling. It is the epithelium which lines the gingival sulcus. It is usually greatest in the incisor region (3.5 to 4.5 mm in the maxilla and 3.3 to 3.9 mm in the mandible). Later on during development, at predetermined sites on the dental lamina corresponding to ten deciduous teeth, further cellular proliferation takes place forming small pro-tuberances. FIGURE 6-1 Normal gingiva. (1949, 1950) 98, 99 estimated the oxygen consumption by normal and healing gingiva using Warburg technique. The basic to neutral keratins have been numbered from K1 to K8 whereas the acidic keratins have been numbered from K9 to K19. The marginal gingiva or unattached gingiva forms the coronal border of the gingiva which surrounds the tooth but is not adherent to it. Research has shown increased expression of integrins 62, intercellular adhesion molecule-1 (ICAM-1) 63, endothelial leukocytes adhesion molecule 1 (ELAM-1)64, 65 and vascular cell adhesion molecule (VCAM)-1 in the inflamed gingiva 62. Archives of oral biology. about 60% of the total oral mucosa. Later on during development, at predetermined sites on the dental lamina corresponding to ten deciduous teeth, further cellular proliferation takes place forming small pro-tuberances. Gosselin F, Magloire H, Joffre A, Portier MM. epithelium except for the lack of stratum corneum and it does not contain clearly defined stratum granulosum. • Keratinisation – protective adaptation , increased by tooth brushing. Periodontium comprises of root cementum, periodontal ligament, bone lining the tooth socket (alveolar bone), and the part of gingiva facing the tooth surfaces (dentogingival junction). Odland bodies are small sub-cellular structures of size 200-300 nm. This … The mucogingival junction is a stable landmark which is probably genetically determined 12. The basal cells show a large number of hemidesmosomes firmly attaching to the lamina densa of the basal lamina. They observed that flat gingival anatomy was found in patients having square teeth while the highly scalloped gingival form was found in patients with a tapered tooth form. Hence, this epithelium is non-keratinized. This is a normal situation, and as the tooth erupts the free gingival margin will ultimately move apically. © 2021 American Academy of Periodontology, I have read and accept the Wiley Online Library Terms and Conditions of Use. ICAM-1 molecule interacts with the leukocyte function associated with antigen-1 and is involved in the transmigration of neutrophil through the epithelium. Adaptation: These tissues have the capability to adapt to the changes in the external environment and wear associated with aging through a continuous process of remodeling and regeneration. Col is a depression between the buccal and lingual papillae which conforms to the interproximal contact area 24. • Reduction of stippling – common sign of Gingival disease. Learn more. Periodontology is the scientific study of the periodontium in health and in disease 1. They concluded that the oxygen quotient (QO ) of the normal gingiva is 1.6 ± 2 0.37. It exhibits no exudate in periodontal health. The interdental gingiva occupies the interproximal spaces between the adjoining teeth. It is demarcated from the attached gingiva by a shallow linear depression, the free gingival groove in approximately 50% of cases 3. gingival stippling the presence of a minutely lobulated surface on the gingiva, like that of an orange peel; it is a normal adaptive process, varying from one person to another.
