Study Notes
Eruption Associated Problems: Key Points
- Eruption hematoma (cyst) occurs due to dental follicle separation, with color ranging from normal to blue-black or brown, and no treatment is necessary unless infected.
- Eruption sequestrum is a small bony deposit related to the occlusal surface of the first permanent molars, usually falling as the tooth erupts.
- Epstein pearls, Bohn nodules, and dental lamina cysts are small white lesions in the mouth, often mistaken for erupting teeth.
- Natal and neonatal teeth, present at birth or within the first 30 days, are usually mandibular primary incisors, managed by preservation unless causing feeding problems.
- Ectopic eruption can result from arch inadequacy, supernumerary or ankylosed teeth, and management depends on the cause.
- Ankylosed teeth result from fusion of cementum and alveolar bone, clinically appearing submerged, with primary mandibular molars showing the highest chances of ankylosis.
- Supernumerary teeth, mesiodentes, and odontomas can disturb tooth eruption, but not all will have an influence, and management involves early diagnosis and surgical removal in most cases.
- Dentigerous cysts, originating from dental follicles of nonerupted teeth, are the most common cysts causing tooth eruption problems.
- Systemic factors such as Down’s syndrome, cleidocranial dysplasia, hypothyroidism, hypopituitarism, and achondroplasia can also impact tooth eruption.
- Other factors like bisphosphonates medications and chemotherapy/radiotherapy related to the head and neck region can influence eruption.
- References include American Association of Paediatric Dentistry guidelines and publications, as well as other dental literature sources.
- The text provides comprehensive information on various local and systemic factors affecting tooth eruption, including specific conditions, cysts, and management strategies.
