Which group of periodontal ligament fibres are responsible for maintaining a tight gingival cuff around each tooth?

The free gingival fibres play a crucial role in maintaining a tight gingival cuff around each tooth. These fibres are part of the periodontal ligament and are specifically oriented to connect the gingiva to the tooth surface. Their arrangement allows for stability and support of the gingival tissue, ensuring that it remains closely adherent to the teeth. This cuffing effect is essential for protecting the underlying periodontium and preventing periodontal diseases by providing a barrier against bacteria and harmful substances.

Understanding the function of the free gingival fibres highlights their importance in periodontal health. Unlike other fibre groups that serve various roles in tooth support and anchoring, the free gingival fibres have a specialized role directly linked to the gingival architecture around each tooth. This emphasizes their significance in maintaining optimal oral health.
