Dental fissures, often seen as simple cracks, are actually connected pits. Organic material and pellicle within fissures and pits can impact sealant retention and may be mistaken for fissure extensions.

Area of Science:

  • Dental Morphology
  • Cariology
  • Restorative Dentistry

Background:

  • Occlusal fissures are complex anatomical features on tooth surfaces.
  • Understanding fissure morphology is crucial for effective preventive strategies like dental sealants.
  • Previous studies have not fully elucidated the detailed structure and composition of occlusal fissures.

Purpose of the Study:

  • To investigate the occlusal morphology of dental fissures.
  • To determine the presence and location of organic material and pellicle within fissures and pits.
  • To assess the continuity of occlusal fissures and their relationship with adjacent enamel structures.

Main Methods:

  • Teeth were split along fissures from base to surface, with confirmation via serial sectioning.

  • Staining techniques were employed to visualize organic material and pellicle within fissures and pits.
  • Extracted molars were examined to determine the buccolingual/linguobuccal extension of occlusal fissures.

    • Main Results:

    • Dental fissures were found to be associations of adjacent pits.
    • Significant amounts of organic material and stained pellicle were observed within fissures and pits, particularly on cusp inclines.
    • Occlusal fissure extensions were frequently interrupted by enamel cols, especially in lower and upper molars.

    Conclusions:

    • Dental fissures are complex pit-and-fissure systems rather than simple linear cracks.
    • The presence of pellicle in fissures and adjacent grooves may be misinterpreted as fissure extensions.
    • Findings have implications for understanding sealant retention and the diagnosis of early caries.
