Aim: To compare Ability of Sodium Hypochlorite to clean dentinal tubules by manual or sonic activation at varying temperature: A Confocal Laser Scanning Microscopic Study.

Introduction: The primary aim of endodontic treatment is to eliminate the microorganism within the root canal system and prevent recontamination. According to Weine, untreated and unfilled lateral canals can retain enough irritants in a protected sanctuary high enough to cause endodontic treatment failure. To achieve the complete cleaning and disinfection, sodium hypochlorite is used as a potent irrigating solution. Studies have been reported that preheating sodium hypochlorite enhances its tissue solubility and disinfection properties. Cavitation and acoustic streaming of the irrigant contribute to the biological chemical activity for maximum effectiveness Many studies have been reported that has studied the effectiveness of sonic instrument on the cleanliness of the canal with sodium hypochlorite. A literature search did not identify any studies evaluating the penetration depth of preheated sodium hypochlorite using sonic instrument by confocal laser electron microscopy.

Methodology: 40 freshly extracted mandibular premolar were collected. Routine endodontic treatment was performed in all teeth of four groups. Teeth were randomly divided into 4 group:

  1. Group 1- Sodium hypochlorite with hand activation
  2. Group 2- Sodium hypochlorite with sonic activation
  3. Group 3- Warm sodium hypochlorite with hand activation
  4. Group 4- Warm sodium hypochlorite with sonic activation.

Following irrigation, all roots were sectioned horizontally at 2mm and 5mm from the apex and examined under a confocal laser scanning microscopy for evaluating the penetration depth of sodium hypochlorite.

Results: Irrigant penetration ability was greater in the middle section then in the apical section.

Sonic irrigation when used with warm sodium hypochlorite had better penetrability in the dentinal tubules of middle and apical then the conventional irrigation.
