Table 5: Summary of treatment modalities for treating hypomineralized first permanent molar

Restoring hypomineralized first permanent molars
Preventive
  • Topical fluoride application

  • Desensitizing toothpaste

  • Apply a CPP-ACP topical creme daily using a cotton bud

  • Glass ionomer cement (GIC) sealants can provide caries protection and reduce surface permeability

Direct restoration
  • Cavity margin placement

    •   –  All defective enamel is removed

    •   –  Only the very porous enamel is removed, until good resistance of the bur to enamel is felt

  • GIC restorations

    •   –  Conventional GIC, resin modified GICs (RMGIC)

    •   –  Adhesive capability to both enamel and dentine

    •   –  Long term fluoride release

    •   –  Poorer mechanical properties

      •   ‒  Not recommended to be used in stress bearing areas

      •   ‒  Be used as an intermediate restoration

  • Composite resin restorations

    •   –  Longer-term stability compared with other restorative materials

    •   –  The polyacid modified resin composites

      •   ‒  Have good handling characteristics

      •   ‒  Release and take up fluoride; and

      •   ‒  Have tensile and flexural strength properties superior to GIC and RMGIC, but inferior to that of resin composite

      •   ‒  Use of PMRCs in permanent teeth is restricted to nonstress-bearing areas

Full coverage restoration
  • When PFMs have moderate to severe PEB, preformed stainless steel crowns (SSCs) are the treatment of choice47

    •   –  Prevent further tooth deterioration

    •   –  Control tooth sensitivity

    •   –  Establish correct interproximal contacts and proper occlusal relationships

    •   –  Are not as technique sensitive or costly as cast restorations

    •   –  Require little time to prepare and insert

    •   –  If not adapted properly may produce an open bite, gingivitis or both

    •   –  Properly placed, SSCs can preserve PFMs with MIH until cast restorations are feasible

  • Partial and full coverage indirect adhesive or cast crown and onlays

    •   –  Compared to SSCs, cast restorations

      •   ‒  Require minimal tooth reduction

      •   ‒  Minimize pulpal trauma

      •   ‒  Protect tooth structure

      •   ‒  Provide high strength for cuspal overlays

      •   ‒  Control sensitivity

      •   ‒  Maintain periodontal health due to their supragingival margins

Extraction and orthodontic consideration
  • Timely extraction is a feasible treatment option in cases of:

    •   –  Severe hypomineralization

    •   –  Severe sensitivity or pain

    •   –  Large multi surface lesions

    •   –  Difficulty of restoration

    •   –  Inability to achieve local anesthesia

    •   –  Behavior management problems preventing restorative treatment

    •   –  Apical pathosis

    •   –  Orthodontic space requirements, where FPM are heavily restored in the presence of healthy premolars

    •   –  Crowding distally in the arch and third permanent molars reasonably positioned

    •   –  Financial considerations precluding other forms of treatment

  • If the orthodontic condition were favorable, the ideal dental age for extracting the defective FPM would be 8.5 to 9 years of age
