Summary

Reinforcing endodontically treated molars with horizontal pins and adhesive provides fracture resistance comparable to intact teeth. This combination offers a favorable prognosis for restoring fractured cusps.

Area of Science:

  • Restorative Dentistry
  • Dental Materials Science
  • Biomaterials Engineering

Background:

  • Endodontically treated teeth are susceptible to fracture due to loss of tooth structure.
  • Facial cusp reinforcement is crucial for the long-term survival of these teeth.

Purpose of the Study:

  • To compare the effectiveness of horizontal pins and dental adhesive in reinforcing facial cusps of endodontically treated mandibular molars.
  • To evaluate the fracture resistance and failure modes of different reinforcement techniques.

Main Methods:

  • Seventy-two mandibular molars were divided into six groups, including intact teeth and various reinforcement methods (dentin adhesive, horizontal pins, or a combination).
  • Teeth were subjected to compressive loading to determine fracture strength using an Instron Universal Testing Machine.

  • Fracture patterns and failure modes were analyzed.

    • Main Results:

    • Intact teeth showed the highest fracture resistance, with Group 4 (pins and adhesive) being comparable.
    • Non-reinforced teeth were significantly weaker than all other groups.
    • Horizontal pins, with or without adhesive, led to more favorable fracture patterns than adhesive alone.

    Conclusions:

    • A combination of horizontal pins and dentin adhesive can reinforce endodontically treated molar cusps to a level not significantly different from intact teeth.
    • Horizontal pins and complete cuspal coverage restorations offer the most favorable prognosis for fractured cusps.
