Physicochemical characterization and nano-emulsification of three species of pumpkin seed oils with focus on their physical stability.

We present the chemical composition, quality parameters and antioxidant capacity of pumpkin seed oils (PSO) from Cucurbita pepo, Cucurbita maxima, and Cucurbita moschata cultivated in Brazil. In addition, PSO nanoemulsions (nanopepo, nanomax and nanomosc) were developed and their physical stabilities were assessed under long-term storage at two temperatures. Among the PSO, C.

A prospective clinical study of polycarboxylate cement in periapical surgery.

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.

Orofacial dermoid cysts in pediatric patients: a review of 8 cases.

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 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.

Ostectomy versus osteotomy with repositioning of the vestibular cortical in periapical surgery of mandibular molars: a preliminary study.

Introduction: Accessing the tooth roots in periapical surgery (PS) requires the elimination of periapical bone.

Objective: To compare the postoperative morbidity and prognosis following PS on mandibular molars by ostectomy, or by osteotomy with repositioning of the vestibular cortical.

Material And Methods: A retrospective clinical study of mandibular molars subjected to PS with ultrasound.

Radiographic morphometric study of 37 periapical lesions in 30 patients: validation of success criteria.

Purpose: The purpose of this study was to establish the midterm prognosis of periapical surgery by use of the ultrasound technique, comparing a scale obtained by image analysis with the success rates according to other prognostic scales.

Materials And Methods: A clinical follow-up study was performed between September 2004 and September 2005. Thirty-six patients with chronic periapical lesions were treated with periapical surgery via the ultrasound technique and root-end filling with silver amalgam.
