Teeth will last for life, unless they are affected by oral diseases or professional interventions. Many retained teeth thus, may be an indicator of positive oral health behavior throughout the life course (1). Tooth longevity is largely dependent on the health status of the periodontium, the pulp or peri-apical region and the extent of reconstructions. Multiple risks lead to a critical appraisal of the value of a tooth (2, 5). Oral implants are nowadays the best solution to replace missing teeth although, a good preoperative assessment, a right evaluation of the jaw bones quality and quantity, and the perfect time for implants placement, all are keys in the success of the procedure and long durability of the implants in the patient’s mouth (3,4).

A 50-years old female patient presented for treatment of the anterior maxillary teeth that had been restored repeatedly in the past with direct resin composite restorations.

The treatment plan for this patient included all-ceramic shell crowns on all anterior maxillary teeth and the premolars. Shell crowns were selected as the treatment option to ensure optimum esthetic result with increased strength on the cervical areas. A knife edge margin was created circumferentially on all prepared teeth. All-ceramic frameworks were fabricated from zirconium oxide and veneered in the layering technique. Full coverage zirconia- based ceramic crowns with knife edge preparations (shell crowns) can offer a good esthetic result with minimum tooth preparation combining strength and could be considered as a treatment option in selected clinical cases.

Accidental finding of a foreign object embedded in a tooth is uncommon. A variety of metallic objects have been discovered inside the pulp/root canals. These foreign objects are mostly self inflicted by patients into the pulp canal and thereby act as potential source of infection. Although most of the techniques mentioned in the literature are effective for the removal of such foreign objects, but still there is no standardized procedure is available for successful removal of unusual foreign metallic objects. Herein, we report a case of a 22-year-old female who presented with a stapler pin lodged in the pulp chamber of mandibular left central incisor, with its successful retrieval using instrument removal system followed by successful endodontic management.
