Figure 1

Preoperative clinical and surgical procedure and radiographic images: IOPA and CBCT images (Case Report 1). (a) Pre-op clinical photograph showing discoloured 11 with chipping of the incisal edge of the crown. (b) Preoperative IOPA showing the periapical lesion involving the apices of 11 and 12 and extending to the mesial margin of 13. (c) Complete curettage of the lesion and apicectomy done in 12. (d) Retrograde preparation and filling with MTA in 11 and 12. (e) CGF fibrin block placed in the bony cavity. (f) CGF membrane placed to cover the bone defect. (g) Pre-op CBCT image showing the lesion measurement in the coronal slice. (h) Post-op CBCT image showing the lesion measurement in the coronal slice. (i) Pre-op CBCT image showing the lesion measurement in sagittal slice corresponding to 12. (j) Post-op CBCT image showing the lesion measurement in sagittal slice corresponding to 12. (k) Pre-op CBCT image showing the lesion measurement in sagittal slice corresponding to 11. (l) Post-op CBCT image showing the lesion measurement in sagittal slice corresponding to 11.
