|Pre-operative x-ray primary tooth K|
|immediate post-operative x-ray|
Patient presented with a symptomatic periapical lesion.
|7 month post-operative x-ray|
Patient had a relatively new crown and we discussed possible retreatment. However, it seemed that a surgical approach would probably be the most appropriate with the best results. Patient understood if a fracture was present, the tooth would be removed. It is obvious from the x-ray that crown-root ratio is very important and has to be taken into consideration when surgically treating these kind of teeth. Every attempt was made to keep the crown-root ratio the same while removing the apical lesion and placing retrofills.
