Pit and Fissure Sealants – History

Pit and fissure sealants provide high susceptibility that help in the control of dental caries and other dental problems. The history of pit and fissure sealants shows that various scientists use different methods for the elimination of caries. In this article, there is a brief discussion on the pit and fissure sealants’history. Read on to know more.

The following is the history of pit and fissure sealants where different dentists and scientist use different methods in the caries prevention.

The following are the methods aimed at eliminating pit and fissure has been tried since the early 1920’s.

    1. Hyatt (1923):

      Hyatt proposed technique called prophylactic odontotomy. This technique consisted of filling the fissures with silver or copper oxy-phosphate cement as soon as the teeth erupted into the oral cavity. Later when they are fully erupted, preparing a small occlusal cavity and filling it with amalgam.

    2. Bodecker (1929):

      Bodecker proposed technique called fissure eradication. This technique involved mechanism eradication of fissures in order to transform deep, retentive fissures into cleansable areas.

    3. Bunocore (1955):

      Bunocore advocated the filling of pit and fissure with bonded resin. He observed that after treatment of the enamel with a concentrated phosphoric acid solution (85%) for 30 seconds, attachment of acrylic resin to the tooth surface is greatly increased.

    4. Mid (1960’s):

      Mid used the first materials as sealants. First materials used experimentally as sealants were based in cynoacrylates but they were never marketed.

    5. Bowen (1965):

      Bowen reported BIS-GMA material development. The basis of BIS-GMA resin is the reaction product of bisphenol A and glycidylmethacrylate.

BIS-GMA is the base resin to most of the current commercial sealants. Urethane dimethyacrylate and other dimethacrylates resins are also used in the sealant materials.
