Combination therapies for the treatment of recurrent central giant cell lesion in the maxilla: a case report.

BACKGROUND: Central giant cell lesion is a non-neoplastic proliferation, usually asymptomatic, of unknown etiology. The purpose of this case report is to report the diagnosis and the treatment of a recurrent central giant cell lesion in the maxilla. CASE PRESENTATION: A 31-year-old Brazilian woman presented to our Surgery Service for evaluation of a cystic lesion in her teeth 13 and 15, although she had previously received endodontic treatment for her teeth 13 and 15 without regression of the lesion. On clinical examination, an increase and painless swelling was observed in her right jaw. An excisional biopsy of the lesion was performed under general anesthesia; the material was sent for pathological examination and a diagnosis compatible with central giant cell lesion was made. She presented again, 10 months after the removal of the lesion, with a recurrent lesion that surrounded her incisors, canine, and right premolar. We suggested that she underwent treatment with intralesional corticosteroids injection. The lesion was significantly reduced and the remainder of the lesion was enucleated. She is monitored at 3-month intervals; at 6 months postoperatively there has been no recurrence. CONCLUSIONS: Central giant cell lesion can have a high degree of invasiveness, which increases the importance of early diagnosis. Combination therapies can provide a favorable prognosis. Periodic monitoring is recommended, thus avoiding the chance of a relapse.

Treatment of Gingival Smile: A Case Report.

There are various alternatives for correcting a gingival smile, ranging from techniques such as gingivectomy to more complex and invasive procedures such as orthognathic surgery. Gingival smile is one of the most common complaints of patients seeking an aesthetic smile. This article describes the alternative treatments available for lip repositioning and improving smile aesthetics, and presents the clinical course of a gingival smile patient after undergoing the surgical technique of gingival recontouring (GR) associated with lip repositioning with restorative aesthetic treatment. The surgery performed corrected altered passive eruption of the maxillary anterior teeth and lengthened the lateral beam of the elevator muscle of the upper lip and wing of the nose, and achieved containment with sutures, reducing the gingival smile. After surgery, it was apparent that the high smile line had been successfully corrected without compromising labial harmony. The patient expressed high satisfaction with the treatment. The surgical technique proposed in this study may be a therapeutic option for lip repositioning to achieve smile harmony.

Pneumatization within a maxillary sinus graft: a case report.

Rehabilitation of edentulous posterior maxilla with implant-supported prostheses frequently presents a challenge to dentists. This is due to insufficient bone within the region, in addition to other limiting factors such as anatomical pneumatization of the maxillary sinus. Thus, grafting of the maxillary sinus is a common procedure used to counteract these problems. Regardless of the type of biomaterial used, the success of the procedure is dependent on the formation of high-quality bone. Therefore, vascularization is a key factor for successful grafting and for the long-term maintenance of the treatment. This paper reports a clinical case of bone graft pneumatization and attempts to elucidate its potential etiology.
