Acetaminophen primarily acts centrally as an analgesic without significant peripheral COX inhibition or impact on prostaglandins, so it doesn't alter bone deposition/remodeling. Ibuprofen, Aspirin, and Dexamethasone all interfere with the bone remodeling process. 

Ibuprofen (an NSAID) inhibits cyclooxygenase (COX) enzymes, reducing prostaglandin E2 production, which slows osteoclast activity and tooth movement (supported by studies like those in American Journal of Orthodontics and Dentofacial Orthopedics, e.g., 2010 review showing NSAIDs delay movement by 30-50%).


Aspirin (another NSAID) similarly inhibits COX, decreasing prostaglandins and impairing bone remodeling, as evidenced by clinical trials (e.g., Angle Orthodontist 2006 study demonstrating reduced tooth movement).

Dexamethasone (a corticosteroid) suppresses osteoblast and osteoclast function via glucocorticoid receptors, inhibiting bone formation and remodeling (confirmed by research in Journal of Dental Research, e.g., 2015 studies showing steroids impair orthodontic response).

Endodontics

A permanent tooth with apical one-third root fracture would most likely remain vital and functional. Apical third fractures have favorable prognosis because: 1) Good blood supply is maintained to the coronal fragment through the periodontal ligament, 2) The fracture is away from the oral environment, reducing contamination risk, 3) Pulp often remains vital due to minimal disruption of apical blood supply, 4) Healing usually occurs with fibrous union between fragments, 5) Function is typically maintained. Root resorption and ankylosis are less common with apical third fractures compared to cervical fractures.

Endodontics

Discoloration of an endodontically treated tooth can result from several factors related to the procedure.
Improper debridement: Inadequate cleaning of the pulp chamber can leave behind necrotic pulp tissue, which contains blood breakdown products that stain the tooth structure.
Sealer cement left in the pulp chamber: Many root canal sealers contain components (like zinc oxide eugenol or certain resins) that can cause staining if left in the coronal part of the tooth after the procedure.
Obturating materials: The main filling material, gutta-percha, especially when combined with certain sealers, can also contribute to tooth discoloration

Chronic hyperplastic candidiasis is distinct because it forms firm, persistent white plaques that cannot be easily wiped off with a gauze. Crucially, these lesions have the potential for epithelial dysplasia and malignant transformation, which is a key differentiating feature from other more common, easily removable forms of oral candidiasis like pseudomembranous candidiasis..

Copro antibodies are antibodies found in feces These are typically IgA antibodies that are produced in response to infections in the gastrointestinal tract, including typhoid fever. They can be detected in stool samples and are used in diagnostic tests.

The correct technique for applying extraction forceps involves placing the beaks as apically as possible onto the root surface, below the cementoenamel junction (CEJ), to ensure a secure grip and to apply force to the root rather than the fragile crown. Placing the beaks on the crown above the CEJ is incorrect and can lead to crown fracture.
