Florid osseous dysplasia (FOD) is a benign process limited tognathic bones. Woman, 76, had hypertension, diabetes, and car-diac problems. She was referred to the Stomatology clinic forevaluation of unspecific jaw pain. Physical examination revealedno disorders. Radiographic examination showed multiple radi-opaque lesions with well-defined borders surrounded by a thincortical line in the apical region of teeth #33, #43, #44, and #45,as well as in the alveolar regions of teeth #25, #34, #35, #36, and#46. Based on the clinicoradiographic features a diagnosis ofFOD was proposed. The clinical approach included drug therapywithout surgical intervention because of the patient’s systemiccondition and in light of the fact that the FOD did not requiresurgical removal. The patient was given analgesics and referredfor dental treatment. At 6-month clinic-radiographic follow-up,no alterations were found. This case demonstrates the impor-tance of adequately managing medically compromised patientswith FOD.

Fibrodysplasia ossificans progressiva (FOP) is a rare geneticdisease characterized by skeletal malformations and ectopic os-sifications in skeletal muscles, tendons, ligaments, and aponeu-rosis. Exacerbation of these ossifications can be caused by dentaltreatment. Man, 26, with a diagnosis of FOP was referred fordental treatment. Conservative dental procedures, such as oralhygiene instructions and recurrent topical fluoride applications,were performed in addition to endodontic and restorative treat-ments. Brief dental appointments were conducted without usingregional anesthesia or dental dam clamps. The dental chair waspositioned at 45� to provide more comfort and to avoid exacer-bating the disease. The patient has now completed 6 months offollow-up and is free of heterotopic ossifications resulting fromdental treatment. The dental treatment modifications implementedfor the present case were sufficient to establish good oral healthand to prevent the formation of heterotopic ossifications in themaxillofacial region.

Bisphosphonates (BPs) are inhibitors of bone resorption usedin the treatment of bone diseases. These drugs have been linked toa debilitating complication, osteonecrosis of the jaws. This studyreports dental care in the pre-, intra-, and postoperative period inpatients treated with BPs. Woman, 52, complained of pain in the

jaw. The patient reported receiving chemotherapy and using BPs(pamidronate sodium) 2 years previously to manage bone me-tastases. The panoramic radiograph revealed the need forextraction of tooth #47. During the procedure, excessive traumato adjacent tissue was avoided and low-power laser was used asadjuvant therapy. The surgery plus laser therapy approach hasbeen successful, with satisfactory healing. However, the patientmust be followed-up closely because the risk of osteonecrosiscontinues indefinitely.

Osteogenesis imperfecta (OI) is a rare autosomal dominantdisorder caused by mutations in the genes COL1A1 or COL1A2associated with changes in type I collagen metabolism. Patientswith OI may have blue sclerae, hearing loss, dentinogenesisimperfecta (DI), growth deficiency, ligamentous laxity, or acombination of these. Bisphosphonate therapy is reported toimprove mobility and bone density and to reduce pain and theincidence of fracture. However, it may also favor the develop-ment of maxillary osteonecrosis, especially after dental surgery.Male pediatric patient with OI but no family history of OI hadpreviously been treated with intravenous bisphosphonate and nowrequired dental surgery. Currently, after 18 months of follow-up,the patient shows no signs of osteonecrosis. The clinical andimaging findings were discussed, along with a brief review of theliterature on treatment and surgical indications in this patientpopulation.

PE-084 - COCKAYNE SYNDROME: CASE REPORT.KARIN SOARES GONÇALVES CUNHA, RAQUELRICHELIEU LIMA DE ANDRADE PONTES, RAFAELAELVIRA ROZZA DE MENEZES, ELOÁ BORGES LUNA,ARLEY SILVA JUNIOR, KARLA BIANCA FERNANDES DACOSTA FONTES, ALEXANDRE TRINDADE SIMÕES DAMOTTA. UNIVERSIDADE FEDERAL FLUMINENSE,NITERÓI-RJ.

Cockayne syndrome (CS) is an autosomal recessive disordercharacterized by several abnormalities, including oral findings. Aclinical case was reported to show to the dental community thecharacteristics of CS. Woman, 25, with CS who had consan-guineous parents presented to the diagnostic service complainingof diastema. She was 115 cm tall, weighed 32 kg, and had acircumference head of 51 cm. She suffered bilateral deafness,psychomotor and mental retardation, dysgeusia, and insomniaand presented a typical facial birdlike appearance. Intraoral ex-amination showed hygiene deficiency, gingivitis, dental apposi-tion, microdontia, lower central incisor diastema, and the absenceof teeth #16, #26, and #48 (confirmed by radiographic exami-nation). CS is a rare condition with several oral manifestations.The oral alterations reported herein are in accordance with reportsin the literature. Knowing about CS is an important aid to dentistsin formulating a diagnosis and providing adequate care andtreatment.
