Oral PathologyCrouzon syndrome is characterized by early synostosis of cranial sutures (craniosynostosis), maxillary hypoplasia, and a prominent nose resembling a "parrot beak." This syndrome is caused by mutations in FGFR2 gene leading to premature fusion of skull sutures, resulting in characteristic facial features including proptosis, hypertelorism, and midface retrusion. Treacher Collins affects mandibulofacial development, Pierre-Robin involves micrognathia, and Marie-Sainton is cleidocranial dysplasia.

Vestibular extension procedure results in an increase in width of non-keratinised
attached gingiva
The vestibular extension procedure is a surgical treatment that involves the
apical movement of the vestibular mucosal tissue to increase the width of
attached gingival tissue around a tooth. This procedure typically does not alter
the width of the keratinized attached gingiva, which is the tissue that is
directly connected to the tooth surface. Instead, it primarily increases the
non-keratinized attached gingival width, which is the part of the gingival
tissue that is not directly attached to the tooth but is still important for
periodontal health and aesthetics.

Compared to the permanent dentition the mesio distal diameter of the primary dentition is larger . The space is used by the mandibular molars and it may correct an end-to-end molar relationship into a normal molar relationship in permanent dentition.

Dental Materials
Potassium sulfate acts as an accelerator by increasing the solubility of the hemihydrate and promoting the formation of dihydrate, which speeds up the setting process.

RadiologyPA (Posteroanterior) view is best for visualizing medially displaced condylar neck fractures. This view provides clear visualization of the condylar region and can show medial displacement of fracture fragments. The AP projection gives better detail of condylar neck positioning.

Advantages of fiber posts over metal posts include bonding to dentin, better esthetics, and a modulus of elasticity similar to dentin, which reduces the risk of root fracture.
