Study Notes
Oral Tissues
Oral tissues are the tissues present in the oral cavity, including the teeth, periodontal tissues, and oral mucosa.
Periodontal Tissues
- Periodontal tissues support the teeth and maintain their position in the jawbone.
- They consist of:
- Gingiva (gums)
- Periodontal ligament (PDL)
- Cementum
- Alveolar bone
Gingiva (Gums)
- Gingiva is the mucous membrane that covers the jawbone and surrounds the base of the teeth.
- It is divided into:
- Free gingiva: the portion of gingiva that surrounds the tooth and is not attached to the tooth or bone.
- Attached gingiva: the portion of gingiva that is attached to the tooth and bone.
Periodontal Ligament (PDL)
- PDL is a group of fibrous connective tissue that connects the tooth to the surrounding bone.
- It anchors the tooth in place and provides sensation to the tooth.
Cementum
- Cementum is a thin layer of bone-like tissue that covers the root of the tooth.
- It provides a surface for the periodontal ligament to attach to.
Alveolar Bone
- Alveolar bone is the bony socket that surrounds the root of the tooth.
- It provides support and anchorage for the tooth.
Oral Mucosa
- Oral mucosa is the mucous membrane that lines the oral cavity.
- It is divided into:
- Masticatory mucosa: the mucosa that covers the gingiva and hard palate.
- Lining mucosa: the mucosa that covers the lips, cheeks, and floor of the mouth.
- Specialized mucosa: the mucosa that covers the tongue and soft palate.
Functions of Oral Tissues
- Support and maintain the position of the teeth
- Provide sensation and proprioception (awareness of tooth position)
- Protect the underlying bone and tissues from injury
- Facilitate mastication (chewing) and speech
- Maintain oral health and prevent disease

- It provides support and anchorage for the tooth.
Oral Mucosa
- Oral mucosa is the mucous membrane that lines the oral cavity.
- It is divided into masticatory mucosa, lining mucosa, and specialized mucosa.

- Protect the underlying bone and tissues from injury
- Facilitate mastication and speech
- Maintain oral health and prevent disease
