Physiological root resorption in primary molars is often uneven, especially in upper molars. Monitoring is crucial to prevent complications from over-retained teeth.

Area of Science:

  • Dentistry
  • Pediatric Dentistry
  • Oral Radiology

Background:

  • Physiological root resorption is a normal process for primary tooth exfoliation.
  • Understanding resorption patterns is key for predicting exfoliation timing and potential complications.

Purpose of the Study:

  • To assess the incidence and patterns of physiological root resorption in primary molars.
  • To identify factors influencing uneven root resorption during exfoliation.

Main Methods:

  • Radiographic assessment using bitewing and orthopantomogram imaging.
  • Evaluation of root resorption in a cohort of primary molars.

Main Results:

  • 36% of examined teeth showed reduced root resorption on one or more roots.

  • Uneven root resorption was common, particularly in upper second primary molars.
  • Factors like premolar-primary molar size discrepancy and permanent tooth position affect resorption patterns.

    • Conclusions:

    • Uneven physiological root resorption is a significant finding in primary molars.
    • Constant monitoring of primary teeth with uneven resorption is necessary to prevent complications like over-retention.
