Ability of laser in removing gutta percha from root canal using chloroform and endosolv
Keywords:
chloroform, diode laser, endosolv EAbstract
Background: Residual necrotic tissue or bacteria beneath gutta percha or sealer can be responsible for periapical inflammation or pain. The present study was conducted to the ability of laser in removing gutta percha from root canal using chloroform and Endosolv E. Materials & Methods: 60 freshly extracted permanent human maxillary central incisors with single and straight root canals were divided into 3 groups based on retreatment method used: group I- only diode laser; group II- diode laser along with chloroform as solvent and group III- diode laser along with Endosolv E as solvent. After completion of retreatment, roots were sectioned longitudinally and viewed under stereomicroscope at 10X magnification. The area of the remaining filling material in each half was measured. Results: The mean percentage area of remaining root canal filling material in group I was 18.2, in group II was 11.7 and in group III was 14.3. The difference was significant (P< 0.05). Conclusion: Diode laser with chloroform and diode laser with Endosolv E were significantly more effective than only diode laser in the removal of gutta-percha from the root canal.
