This in vitro study evaluated temperature rises on the outer root surfaces of cats canine teeth during the Thermafil Plus filling technique. Twelve extracted cat canine teeth were used. After root canal cleaning and shaping, the teeth were filled with Thermafil Plus and AH Plus root canal sealer. Temperature changes on the whole mesial outer surfaces of the roots were measured using an infrared thermal imaging camera. The results of this in-vitro study showed that the use of the Thermafil Plus technique to fill canine teeth in cats produces a temperature rise below the critical level and therefore should not damage the periodontal ligament and/or the surrounding attachment apparatus.
