The Case: 

A 7-year-old male patient came to my clinic for a 6-month recall examination and cleaning. We had placed two occlusal-lingual resin restorations one year earlier to repair carious lesions on teeth # A and J. There was organic debris present in all pit and fissures of the fully erupted 6-year molars (Figure 1), but not in the primary teeth. When questioned, the caregiver stated that the patient brushes his teeth with no parental supervision and had brushed just before coming to this exam.

All first permanent molars were free of decay, and after consent was obtained, the patient was prepared for sealants on all the permanent molars. The Isolite device was chosen for its ability to treat opposing molars simultaneously. A thorough air-water blast was used to assess if a fissurotomy was indicated or if we should proceed with a non-abraded sealant procedure. Thorough cleaning and air-water blast were not sufficient to remove the organic debris from the permanent molars, so I chose a 330 bur to lightly prepare each groove.

This technique requires only a gentle approach to round the deep grooves, not the normal preparation for a cavity. After preparation, 37% phosphoric acid was applied to the enamel for 20 seconds, rinsed, and lightly dried, removing all surface water, but not desiccating the tooth. Embrace WetBond Pit and Fissure Sealant was applied to the grooves and cured for 20 seconds.

An explorer examination was performed to check the margins and attempt to remove the sealant from the tooth-sealant interface. No detectable margin was present.
