Torus mandibularis and Ankyloglossia

 Torus mandibularis 

Definition 

     An exostosis that develops along the lingual surface of the mandible.

Clinically 

     Presents as a bilateral bony mass along the lingual surface of the mandible in the premolars

        region above the mylohyoid line.

Clinical significance 

     The thin overlying mucosa may become ulcerated secondary to trauma.

     It interferes with complete denture stability.

NB: 

The mylohyoid line is a ridge on the inner side of the bone of
the lower jaw extending in front to the last molar on each
side and giving attachment to the mylohyoid muscle.

Ankyloglossia (Tongue-tie) 

    Definition 

     Ankyloglossia is a congenital oral anomaly in which there is limitation of tongue movement.

     It is caused by an unusually short, thick lingual frenum, a membrane connecting the ventral

        surface of the tongue to the floor of the mouth.

    Clinical features and types 

     Partial ankyloglossia 

        This condition is characterized by a short, thick lingual frenum which is attached near the tip

        of the tongue.

     Complete ankyloglossia 

       A rare condition in which the tongue is fused to the floor of the mouth.

    Clinical significance 

     Ankyloglossia can affect feeding and speech.
