EndodonticsCommon sequelae of replanted avulsed tooth are ankylosis and resorption of roots. These complications occur due to: 1) Periodontal ligament damage during avulsion and handling, 2) Extended extraoral time leading to PDL cell death, 3) Inflammatory response triggering resorptive processes, 4) Direct bone-root contact causing ankylosis, 5) Root surface damage predisposing to replacement resorption. These complications are more common when extraoral time exceeds 30 minutes or when the tooth is stored in inappropriate media. Proper immediate management can reduce but not eliminate these risks.

PeriodonticsWhile changing attitudes and providing information are important, the primary goal of patient education in dentistry is to encourage behavioral changes that lead to improved oral hygiene practices. This may include consistent brushing and flossing, dietary changes, and regular dental visits.

Pathology
Head and Neck: The head and neck region includes various structures such as
the oral cavity, nasal cavity, pharynx, larynx, and the salivary glands. This
region is highly susceptible to carcinomas due to the presence of mucosal
surfaces exposed to potential carcinogens. Common types of head and neck
carcinomas include:
- Oral Squamous Cell Carcinoma: This is the most common form of head and neck
cancer, typically occurring on the tongue, lips, oral cavity, and oropharynx.
Risk factors include tobacco use (smoking and smokeless), alcohol consumption,
and human papillomavirus (HPV) infection.
- Nasopharyngeal Carcinoma: This cancer arises from the nasopharynx and is often
associated with environmental factors such as the Epstein-Barr virus (EBV)
infection and dietary habits.
- Laryngeal Carcinoma: Cancer of the larynx (voice box) is often linked to
smoking and excessive alcohol intake.

The elastic limit of a wire is the point at which it yields permanently, meaning any greater force applied will result in irreversible deformation.
