A clinical case of First class direct restorations on 4.6 and 4.7

Simona Chirico


A female 32-year-old patient came to my attention for a visit at the Master of Restorative and Aesthetic Dentistry in University of Bologna, because she perceived the presence of a cavity at the level of the first right lower molar.  The general medical history was negative. The oral examination revealed the presence of a carious lesion on element 4.6 and an old incongruous restoration on 4.7. Everything was also confirmed by the radiographic examination. In addition, both elements were positive for the pulp viability test, thus finding the absence of an irreversible pulpitis.
The percussion test was negative.  

TREATMENT PLAN
 -Professional oral hygiene session, 
 - First class direct restorations of 4.6 and 4.7  

The clinical case is illustrated below.
