Root resorption following slow maxillary expansion.

E Lilja, L Odenrick

    Swedish Dental Journal. Supplement
    |January 1, 1982
    PubMed
    Summary

    Slow maxillary expansion can cause root resorption in premolars, identified through histological analysis. While radiographs showed no resorption, histological examination revealed arrested or repaired resorption lacunae on the tooth surface.

    Area of Science:

    • Orthodontics
    • Dental Histology
    • Craniofacial Development

    Background:

    • Slow maxillary expansion (SME) is a common orthodontic treatment.
    • Understanding potential side effects like root resorption is crucial for patient safety.
    • Previous studies have yielded mixed results on the extent of root resorption during SME.

    Purpose of the Study:

    • To investigate the occurrence and nature of root resorption in patients undergoing SME.
    • To compare radiographic and histological findings of root resorption.
    • To characterize the types and locations of resorption lacunae.

    Main Methods:

    • Radiographic analysis of premolars in patients treated with SME.
    • Histological examination of premolar sections.
    • Polarized light microscopy to analyze reparative cementum.

    Main Results:

    • Radiographs did not detect any root resorption.
    • Histological sections revealed resorption lacunae, classified as active, arrested, or repaired.
    • Most resorption occurred on the bucco-marginal side and was arrested or repaired.
    • Reparative cementum differed from normal cementum, with no new fiber attachment.

    Conclusions:

    • Histological analysis is more sensitive than radiography for detecting root resorption during SME.
    • SME can induce root resorption, predominantly of the arrested or repaired type.
    • The reparative cementum formed does not fully integrate with the periodontal ligament, potentially affecting long-term stability.
