Magnifying the decay
Capt. Brian Blackwell, a 92nd Aerospace Medicine Squadron general dentist, assisted by Staff Sgt. Adam Lloyd, a 92nd AMDS dental assistant, applies a special bleaching agent to a tooth’s discolored root canal of Staff Sgt. Benjamin W. Stratton, a 92nd Air Refueling Wing public affairs photojournalist, in the base dental clinic at Fairchild Air Force Base, Wash., March 16, 2015. During a root canal treatment, the inflamed pulp is removed and the inside of the tooth is carefully cleaned and disinfected, then filled and sealed with a rubber-like material. Similarly, in Stratton’s case, the previously sealed tooth is unsealed, bleached, and filled back in. Depending on the extent of the discoloring, the process can take several appointments to complete. (U.S. Air Force photo/Staff Sgt. Benjamin W. Stratton)
