Cementum, the tooth root tissue, shares similarities with bone but its formation remains unclear. This review examines cementum development and changes with age and mechanical stress in rat molars.

Area of Science:

  • Biomineralization
  • Dental Tissues
  • Periodontal Ligament

Context:

  • Cementum is a mineralized tissue covering tooth roots.
  • It provides attachment for the periodontal ligament.
  • Its extracellular matrix resembles bone, but its formation is not fully understood.

Purpose:

  • To review cementum formation and age-related changes.
  • To discuss the influence of mechanical stress on cementum development.
  • Focuses on cellular and acellular cementum in rat molar roots.

Summary:

  • Cementogenesis, the biological process of cementum formation, is complex and influenced by factors like age, species, and tooth position.
  • Variations in cementum's distribution and mineral content are observed across different conditions.

  • This review synthesizes current knowledge on cementum development, particularly in rat molars, under varying mechanical loads.

    • Impact:

    • Provides insights into the biological basis of cementogenesis.
    • Highlights the role of mechanical stress in regulating cementum formation.
    • Contributes to understanding age-related alterations in dental tissues.
