ABSTRACT
This case report presents the periapical surgical retreatment of an Oehlers Class III invaginated maxillary central incisor with extruded root canal filling into the periapical lesion. After local anesthesia, a full-thickness mucoperiosteal flap was reflected, and the granulomatous tissue and extruded gutta-percha points were curetted carefully. A deep and wide root-end cavity was prepared and filled with mineral trioxide aggregate (MTA). At 6 months and 2 years after the treatment, the tooth exhibited no clinical symptoms, and the radiograph performed during the 2-year follow-up showed a complete periapical healing around the root end. The present report indicates that MTA retrofilling can be used successfully in the surgical retreatment of dens invaginatus type III cases in which the invagination exits apically.
ABSTRACT
Suction cups, which provide high retention, are not being recommended anymore because of the destructive effect of the negative pressure on the palatal tissues. It is known that dentures with suction cups can cause perforations in the palate. In this case report, an oronasal communication caused by a denture with suction cup in a patient who had previously undergone pleomorphic adenoma excision of the palate is presented. Disadvantages of suction cups are emphasized.

OBJECTIVE: The purpose of this study was to compare the effects of tube drainage versus a single dose of methylprednisolone (MP) on maximal mouth opening, facial swelling, and pain after third molar surgery. STUDY DESIGN: Twenty-two patients requiring extraction of bilaterally impacted mandibular third molars were selected. Each patient had 2 operations. In the first operation, a drainage tube was inserted into the buccal fold after the suture procedure and left there for 3 days. In the second operation 1 month after the first surgery, 1.5 mg/kg intravenous methylprednisolone was administered 1 hour before the surgery. The patients were evaluated by the same person for maximal mouth opening, facial swelling, and pain in the immediate preoperative time point and on the second, fifth, and seventh days after surgery. RESULTS: There was a statistically significant difference in mouth opening on fifth and seventh days but none in facial swelling and pain between MP group and drain group. CONCLUSION: We conclude that the use of a drain or methylprednisolone is useful in reducing postoperative discomfort after third molar surgery.

Distraction osteogenesis of the edentulous alveolar ridges may be considered an alternative to many other augmentation oriented surgical techniques. It is now being widely used for treating severe forms of alveolar ridge atrophy, especially before the placement of dental implants. Leibinger Endosseous Alveolar Distraction System (LEAD; Stryker Leibinger, Kalamazoo, MI) is an intraosseous distraction device used for edentulous ridges. In this study, the healing was uneventful in all 5 cases that were treated except 1, in which the vitality of the distraction segment could not be maintained. No complications related to the prosthodontic restoration were observed.
