Purpose: The following case report is about the surgical management of a case of inflammatory gingival hyperplasia with a proportionate design of the anterior teeth to achieve an aesthetic appearance.
Material and Methods: A treatment was planned for smile designing using Chu’s Esthetic Gauge to contour the gingiva followed by simple gingivectomy and gingivoplasty using a 15 BP blade.
Conclusion: The use of Chu’s Aesthetic Gauge gave an easy and accurate measurement for esthetic designing of the anterior crowns producing a good esthetic result. This instrument is used to accurately design the gingival contours of the crowns, thus allowing an aesthetic outcome of such a surgery.
For a successful endodontic treatment, removal of all pulp tissue and bacteria from the root canal is crucial. This cannot be performed without the proper determination of the working length of the canal. The working length of a tooth is between the coronal reference point and the end of the canal where preparation and obturation should stop. Several methods have been used for working length determination; tactile method, radiographic method, electronic method and 3D imaging.
Aim of the Study: to compare between CBCT and conventional radiography with apex locator in determination of working length in curved root canals.
Methods: 18 canals were included in this study. Working length in each root canal was determined by two methods; CBCT scan and conventional radiography confirmed with electronic apex locator (Root ZX).
Results: There was no statistically significant difference between the two methods (p value = 0.7). Conventional radiography confirmed with electronic apex locator (mean value = 21.05) CBCT scan method (mean value= 20.9).
Conclusion: No difference was found between using CBCT and conventional radiography with apex locator for working length determination. In curved root canals, it is recommended to use electronic apex locator in combination with conventional radiography without the need for CBCT.
