ProsthodonticsThe Bennet movement is a type of movement that occurs in the temporomandibular joint (TMJ) during the lateral excursion of the mandible, particularly when the mouth is open. It involves the sliding of the articular disk in a lateral direction within the joint space, which allows for the condyle to move smoothly along the articular eminence of the temporal bone. This movement is essential for the normal functioning of the TMJ during activities like chewing and speaking. It is the first type of movement to occur during lateral excursion and is crucial for maintaining the proper alignment of the TMJ components during side-to-side jaw motion.

1. Anodontia: This is the complete absence of teeth. It is a rare condition
where an individual fails to develop any teeth.
2. Oligodontia: This term is used when an individual has fewer teeth than the
typical dental formula, which is six incisors, two canines, two premolars, and
six molars in the permanent dentition (excluding the third molars or wisdom
teeth). The term "hypodontia" is often used synonymously with oligodontia, but
hypodontia can also refer to a broader range of conditions characterized by the
congenital absence of one or more teeth, whereas oligodontia is more
specifically the absence of six or more teeth.
3. Microdontia: This condition involves teeth that are smaller than normal. It
can affect either the primary or permanent dentition and may involve one tooth
or multiple teeth.
4. Dens in dente: This is a rare developmental anomaly where a tooth forms
within the dental crown of another tooth, typically in the form of a small
tooth-like structure. It is not a condition of tooth number but rather an
abnormality of tooth structure.

Gingivitis is the inflammation of the gums that is more common in children due to poor oral hygiene and accumulation of dental plaque.
Periodontitis, on the other hand, is a more severe form of gum disease that typically occurs in adults due to prolonged or severe gingivitis.
ANUG (Acute Necrotizing Ulcerative Gingivitis) is a specific type of severe gingival infection that is less common in children than gingivitis, and
pericoronitis is an infection that occurs around the gum flap when a tooth is partially erupted, which is more common in teenagers and young adults.
