ABSTRACT SUMMARY:
•PROSPECTIVE STUDY – 100 PATIENTS
•MESIO ANGULAR IMPACTED TOOTH NEAR TO IANC
•OBJECTIVE- EVALUATE THE BETTER TECHNIQUE i.r.t. IAN DAMAGE.
•2 GROUPS – A- 50- TOOTH SECTIONINING NOT PERFORMED
- B- 50- TOOTH SECTIONING PERFORMED
• FOLLOW UP – 7,15,30,90,180 DAYS.
• 13 PT SUFFERED NERVE DAMAGE- ALL RECOVERED EXCEPT 1 PATIENT
AFTER 180 DAYS
• OTHER RISK FACTORS-
• Deviation of IANC
• Increased depth of impacted tooth
• Intraoperative hemorrhage within socket
• Nerve exposure
• Increased duration of procedure
