Teeth

The formation of teeth, also known as odontogenesis, is a complex process that begins in utero, around the sixth week of embryonic development. There are three stages to this process: the bud stage, the cap stage, and the bell stage.
In the bud stage, the tooth germ (an aggregation of cells) starts to form in the developing jawbone. During the cap stage, the tooth germ differentiates into enamel organ, dental papilla, and dental sac, which will later develop into the tooth's enamel, dentin and...

The presence of a mandibular third molar can significantly increase the risk of a mandibular angle fracture. This study suggests the risk may double, highlighting the importance of considering third molar presence in fracture prevention strategies.

Area of Science:

  • Oral and Maxillofacial Surgery
  • Biomechanics
  • Dental Research

Background:

  • Mandibular angle fractures are common facial injuries.
  • The influence of mandibular third molars on fracture risk is not fully understood.
  • Previous studies have yielded varied results regarding third molar impact on mandibular biomechanics.

Purpose of the Study:

  • To estimate the magnitude of impact of mandibular third molars on mandibular angle stiffness.
  • To quantify the association between the presence of third molars and mandibular angle fracture risk.

Main Methods:

  • A systematic literature search was conducted on MEDLINE and LILACS databases.
  • Inclusion criteria focused on cohort studies of patients with mandibular fractures and third molars, similar angle fracture definitions, and statistically analyzable data.

Measuring Maxillary Posterior Tooth Movement: A Model Assessment using Palatal and Dental Superimposition

Published on: February 23, 2024

  • Four studies involving 2533 patients were included in the meta-analysis.

    • Main Results:

    • The relative risk of mandibular fracture in patients with third molars ranged from 1.18 to 2.25.
    • A pooled relative risk of 1.94 (95% CI 1.6 - 2.35) was estimated across the included studies.
    • The presence of a third molar was associated with a nearly twofold increase in the risk of mandibular angle fracture.

    Conclusions:

    • The presence of a mandibular third molar may double the risk of a mandibular angle fracture.
    • Further research is needed to identify specific conditions related to third molars that influence fracture risk.
    • The findings necessitate further investigation into the prophylactic removal of third molars in populations with higher fracture predisposition.
