RESUMO
OBJECTIVE: To evaluate the clinical efficacy of polycarboxylate cement as retrograde filling material. DESIGN: A prospective clinical study was made of 25 patients subjected to periapical surgery with ultrasound and magnifying loupes, in which polycarboxylate cement was used as retrograde filling material. Measurements were made of the area and diameter of the lesions pre- and postoperatively, and 6 and 12 months after the operation. The apical resection and retrograde filling areas were also measured, and the prognosis following surgery was recorded. RESULTS: A total of 23 patients with 31 apicoectomized teeth were studied (2 patients being lost to follow-up). The mean area of the periapical lesions before surgery was 52.25 mm2, with a mean major diameter of 6.1 mm and a mean lesser diameter of 4.8 mm. The success rate after 12 months was 54.7%, according to the criteria of Von Arx and Kurt. The prognosis was poorer in females, in larger lesions, and in cases with larger retrograde filling areas. CONCLUSIONS: Polycarboxylate cement offers good results, with important bone regeneration after periapical surgery.

Objective: The aim was to analyze the clinical characteristics, treatment and outcome of 8 orofacial dermoid cysts(DC) in pediatric patients.Material and Methods: A retrospective observational study was made, reviewing the medical records with clinicaldiagnosis of dermoid cyst between 1987 and 2006 in the Childrens Maxillofacial Surgery Department of the HospitalUniversitario La Fe, Valencia, Spain. The following data were collected: sex, age, location, size and durationof the lesion, treatment, length of follow-up, and recurrence.Results: Eight patients (3 girls and 5 boys) with a mean age of 2.7 years (range 0-12 years). Four DC were located inthe oral area (3 sublingual and 1 lingual), one in the periorbital and three in the nasal areas. The size ranged from0.8 cm to 4 cm. The mean duration of the lesion was 13.7 months (range 4 days to 2 years). All DC were diagnosedpathologically following surgical removal of the lesion. There were no recurrences.Conclusion: The appearance of DC in the maxillofacial region of pediatric patients is uncommon. The floor of themouth is the most frequently affected area in the oral cavity. Treatment is surgical removal of the lesion. Recurrenceis unusual (AU)

MATERIAL AND METHODS: A retrospective observational study was made, reviewing the medical records with clinical diagnosis of dermoid cyst between 1987 and 2006 in the Children's Maxillofacial Surgery Department of the Hospital Universitario La Fe, Valencia, Spain. The following data were collected: sex, age, location, size and duration of the lesion, treatment, length of follow-up, and recurrence. RESULTS: Eight patients (3 girls and 5 boys) with a mean age of 2.7 years (range 0-12 years).

The mean duration of the lesion was 13.7 months (range 4 days to 2 years). All DC were diagnosed pathologically following surgical removal of the lesion. There were no recurrences. CONCLUSION: The appearance of DC in the maxillofacial region of pediatric patients is uncommon. The floor of the mouth is the most frequently affected area in the oral cavity. Treatment is surgical removal of the lesion. Recurrence is unusual.
