Study Notes
Understanding Oral Epithelium and Connective Tissue
- The oral epithelium is connected to the connective tissue through connective tissue papilla and red pegs.
- The base of the sulcus is formed by the top of the junctional epithelium.
- The most apical cell of the junctional epithelium in a healthy periodontal is at the CEJ.
- The basement membrane separates the basal layer and the underlying connective tissue, consisting of lamina lucida and lamina densa.
- The basement membrane is attached to the basal cells with connecting fibers synthesized by fibroblasts.
- Hemi desmos forms are between the basement membrane and the epithelial cells, while desmos forms are between the epithelial cells themselves.
- The oral epithelium is a stratified squamous epithelium that serves as a barrier against mechanical injury and other threats.
- The oral epithelium contains four cell layers: basal, prickle, granular, and keratinized layers.
- The differences between ortho and parakeratinized epithelium lie in the presence of cell nuclei in the keratin layer.
- The basal layer of the oral epithelium undergoes mitotic division until the cells mature and move to the top layer for renewal.
- The pre-layer of the oral epithelium is the widest cell layer containing cytoplasmic processes and desmosome connections.
- The connection between the oral epithelium and the connective tissue is mainly through hemi desmos forms and desmosome connections.
Understanding Periodontal Anatomy
- The presence of the free gingival groove does not necessarily indicate disease, and it may not always coincide with the sulcus.
- In a healthy periodontal, the sulcus is a shallow groove between the gingival margin and the tooth, without an actual pocket or opening.
- The dental papilla's architecture depends on the size and shape of the teeth and their contact, with more scalloped architecture in the anterior and flatter architecture in the posterior.
- The shape of the papilla varies depending on the contact of the teeth, with anterior teeth forming a pyramid and posterior teeth forming a flatter architecture.
- The col space, a thin non-keratinized epithelium between teeth, is a common site for disease to start due to its susceptibility to bacterial colonization.
- Disease and inflammation frequently start in the interdental spaces due to the thin, non-keratinized nature of the col space.
- The attached gingiva, located below the free gingival groove, has a stippled surface due to connective tissue fibers and is firmly attached and non-mobile.
- The presence or absence of stippling does not indicate disease, as healthy tissues may or may not show stippling.
- Understanding the relationship between enamel and root surfaces is crucial for diagnosis, as probing the root surface indicates attachment loss and potential disease.
- The free gingival groove is a small indentation on the labial surface, located on the most apical border of the junctional epithelium.
- The sulcus is a shallow groove between the gingival margin and the tooth, and the presence or absence of a groove does not necessarily indicate periodontal health.
- The dental papilla's architecture is influenced by the size and shape of the teeth and their contact, with different architectures in the anterior and posterior regions.
