Intraoral Approach for Surgical Treatment of Psammomatoid Juvenile Ossifying Fibroma.

Psammomatoid juvenile ossifying fibroma (PJOF) is a rare benign tumor that usually affects the paranasal sinuses, orbit, and skull. In most cases, extensive incisions are necessary for full access to the tumor site. The aim of this paper is to report a case of extensive PJOF in which an intraoral surgical approach was performed with complete excision of the tumor. A female patient, 18-year old had a deforming volume increase in the region of the left facial middle third with an approximate evolution time of 2 years. She complained of headache, epiphora in the left eye, and total obstruction of the left nostril. Extraoral examination showed facial asymmetry with dystopia, ocular proptosis, and considerable sclera exposition of the left eye. Tomography examination showed a mixed aspect lesion on the left side of the face, well delimited. The intraoral surgical approach was chosen for the excision of the lesion. Under general anesthesia and nasotracheal intubation, total resection was performed, followed by exodontia of the directly involved teeth. In the definitive histopathological examination, the diagnosis was confirmed. The patient is currently with 2 years and 6 months of postoperative follow-up and has good healing of intraoral surgical wounds and stable occlusion. Extraoral examination showed harmonic projection of the facial middle third, but still with excessive exposure of the sclera of the left eye due to the defect in the orbital floor. The surgical treatment of PJOF was possible by intraoral approach, even taking into account the limitations of the access and the complexity of the anatomy of the facial bones involved.

Comparative Analysis Between Computed and Conventional Inferior Alveolar Nerve Block Techniques.

OBJECTIVE: The aim of this randomized, double-blind, controlled trial was to compare the computed and conventional inferior alveolar nerve block techniques in symmetrically positioned inferior third molars. PATIENTS AND METHODS: Both computed and conventional anesthetic techniques were performed in 29 healthy patients (58 surgeries) aged between 18 and 40 years. The anesthetic of choice was 2% lidocaine with 1: 200,000 epinephrine. The Visual Analogue Scale assessed the pain variable after anesthetic infiltration. Patient satisfaction was evaluated using the Likert Scale. Heart and respiratory rates, mean time to perform technique, and the need for additional anesthesia were also evaluated. RESULTS: Pain variable means were higher for the conventional technique as compared with computed, 3.45 ±â€Š2.73 and 2.86 ±â€Š1.96, respectively, but no statistically significant differences were found (P > 0.05). Patient satisfaction showed no statistically significant differences. The average computed technique runtime and the conventional were 3.85 and 1.61 minutes, respectively, showing statistically significant differences (P <0.001). CONCLUSIONS: The computed anesthetic technique showed lower mean pain perception, but did not show statistically significant differences when contrasted to the conventional technique.

Piercing labial como corpo estranho / Lip piercing as a foreign body

O uso do piercing oral se tornou muito comum na última década. o uso disseminado desse adereço pode trazer consequências na região bucal, relacionadas à instalação e permanência deste. A presença de piercings como corpoestranho inserido nos tecidos orais é pouco relatada pela literatura. este artigo tem como objetivo realizar uma revisão da literatura sobre piercing bucal e relatar um caso adicional de piercing lábio como corpoestranho.

Oral piercing has become very common over the last ten years. The widespread use of piercing may have consequences in the oral region related to installation and maintenance. The presence of foreign body piercings inserted into the oral tissues is rarely reported in the literature. This article sets out to review the literature on oral piercing and report an additional case of lip piercing as a foreign body.
