TI  - Comparison of micromorphological changes in enamel using SEM analysis after 
      conventional and erbium, chromium:yttrium, scandium, gallium, and garnet

AB  - BACKGROUND: Well articulated by John Knowles - "Everything has to evolve or else 
      it perishes." With the paradigm shift of emphasis toward the prevention of dental 
      caries, it has been proven that laser irradiation protects against both caries 
      initiation and caries progression. AIM: The aim of the study was to evaluate and 
      compare the micromorphology of caries-free extracted premolars using a Scanning 
      electron microscope (SEM) after fissurotomy by conventional fissurotomy bur and 
      erbium, chromium: yttrium, scandium, gallium, and garnet (ER, CR: YSGG) 
      hard-tissue laser. METHODOLOGY: Sixty caries-free premolars extracted 
      atraumatically for orthodontic treatment were included in the study. The samples 
      were divided into two groups randomly (Group 1: fissurotomy by bur, n = 30, and 
      Group 2: fissurotomy by hard-tissue laser, n = 30). Each sample was further 
      divided into halves from the occlusal surface wherein one-half of the occlusal 
      surface received fissurotomy procedure and the other half was control. Samples 
      were analyzed by scanning electron microscopy (SEM) for micromorphological 
      changes. RESULTS: Profile image of control samples revealed the disorganization 
      of enamel surface at the junction of fissures forming a heterogeneous tissue and 
      agglomeration of enamel with deep pit and fissure. On the contrary, the image of 
      experimented samples (with laser fissurotomy) showed smooth enamel surface and 
      homogeneous enamel subsurface with wider pit and fissure owing to self-cleansing 
      ability. CONCLUSION: On the grounds of the present study results, it could be 
      concluded that the intervention of ER, CR: YSGG hard-tissue laser possesses 
      self-cleansable pit and fissures for caries prevention and has the potential to 
      irradicate the smear layer entirely for superior attachment of remineralizing 
      agents.
