The diagnosis of the vitality of a tooth plays a crucial role in endodontics.Doppler flowmetry,Cholesteric crystals, Pulse oximetry are some of the newer methods used in access pulp vitality.. Thermographic imaging is a non-invasive and highly accurate method of measuring the surface temperature of a body. The aim of the study was to evaluate if this device could be used in routine clinical practice to access pulp vitality.Seventy five single rooted anterior teeth were examined. The teeth were rubber dam isolated. Baseline temperature of the tooth was recorded using the I.R thermometer. A Cotton swab was sprayed with Endo-Frost (Coltene) and was held for 20 seconds. Surface temperature was noted. Surface temperatures were then continuously monitored for the next 3 minutes. The procedure was repeated on the contralateral tooth. Conventional pulp vitality tests were also conducted on both the teeth. The test tooth was anaesthetized and a conventional access cavity was prepared. The status of extirpated pulp tissue was noted as Vital or Necrosed.Both vital and non-vital teeth had similar baseline temperatures. The mean average of the baseline temperatures of the Vital tooth group was 34.3+_0.3 degrees, and the non-vital tooth group was 34+_0.8 degree(p>0.05)s.A 97.34% clinical success rate in diagnosing pulp vitality status was seen(p<0.05).2+_0.6 degrees was seen to be the pattern of the rewarming profile(p>0.05).Vital teeth rewarmed faster than non vital teeth. Laser guided Infrared thermometry may be used as a routine pulp vitality test in clinical setup and is an easy and reliable tool.
