|Preoperative x-ray #4|
Tooth is symptomatic.
|Immediate post operative x-ray #4|
Obturation with 2 lateral canals.
|2 month post operative check #4|
Tooth is asymptomatic.
|6 year post operative x-ray #4|
Note: resorption of lateral canal filling material. Probably just sealer only, gutta percha does not dissolve. Lateral lesions have healed.
Please note: Apical lesion on #5.
|7 year post operative xray|
If lateral canals are not filled i.e. cleaned, there is a good chance that a tooth's apical area will never heal.
In most cases, it is impossible to mechanically cleanse an lateral canal system. However, sodium hyperchloride may chemically clean a lateral canal. In most of my cases, if a lateral canal is filled it is with softened gutta percha and sealer. This is speculation on my part, however.
