ABSTRACT
OBJECTIVES: To compare upper lip frenulum reinsertion, bleeding, surgical time and surgical wound healing in frenectomies performed with the CO2 laser versus the Er, Cr:YSGG laser. STUDY DESIGN: A prospective study was carried out on 50 randomized pediatric patients who underwent rhomboidal resection of the upper lip frenulum with either the CO2 laser or the Er,Cr:YSGG laser. Twenty-five patients were assigned to each laser system. All patients were examined at 7, 14, 21 days and 4 months after the operation in order to assess the surgical wound healing. RESULTS: Insertion of the frenulum, which was preoperatively located between the upper central incisors, migrated to the mucogingival junction as a result of using both laser systems in all patients. Only two patients required a single dose of 650 mg of paracetamol, one of either study group. CO2 laser registered improved intraoperative bleeding control results and shorter surgical times. On the other hand, the Er,Cr:YSGG laser achieved faster healing. CONCLUSIONS: Upper lip laser frenectomy is a simple technique that results in minimum or no postoperative swelling or pain, and which involves upper lip frenulum reinsertion at the mucogingival junction. The CO2 laser offers a bloodless field and shorter surgical times compared with the Er,Cr:YSGG laser. On the other hand, the Er,Cr:YSGG laser achieved faster wound healing.

La actividad asistencial de los profesionales de la Odontología tiene como consecuencia una baja disponibilidad de tiempo para dedicarse a la lectura de artículos científicos. Ante la dificultad de mantener un buen nivel de información en el campo de la Implantología Bucofacial, nuestro intereses exponer de forma sintética una revisión de la literatura científica publicada en las revistas más relevantes de la especialidad durante el año 2008. El lector interesado encontrará en este artículo algunos de los diferentes temas que integran esta disciplina, expuestos por apartados (regeneración ósea guiada, técnicas avanzadas, elevación del suelo del seno maxilar, mini implantes, plasma rico en plaquetas, factores de crecimiento, tejidos blandos y complicaciones) (AU)
The lack of the available time of the professionals involved in the Odontologic field and the difficulty to maintain a good level of information about Oral Implantology, arouses the interest of the authors to expose a synthetic review of the publications. Inside this article there are different aspects related to guided bone regeneration, advanced techniques, sinus lift, mini-implants, platelet rich plasma, growth factors, soft tissues and complications (AU)

Diffuse large B-cell lymphoma is the most common type of non-Hodgkin lymphoma and is characterized by the appearance of rapidly developing tumor lesions in the lymph nodes, spleen, liver, bone marrow or other organs. Primary extranodal presentations of this entity in bone are rare (5% of all extranodal lymphomas) and their initial manifestation is usually in the form of a single bone lesion. This paper addresses a case of a 62-year-old male diagnosed with diffuse large B-cell lymphoma in the mandible. The patient had left mandibular swelling with intermittent paresthesia of the left lower lip and chin, without apparent neck adenopathies. No other locations were identified in the several exams performed, and the final diagnosis was an asymptomatic diffuse extranodal large B-cell lymphoma (IE-A) in the body of the left mandible. Four cycles of chemotherapy were given according to the R-CHOP protocol (rituximab, cyclophosphamide, doxorubicin, vincristine, prednisone) plus external radiotherapy targeted to the involved site, resulting in complete remission of the tumor. Such lesions are fairly uncommon in daily clinical practice. However, considering their severity and the importance of an early diagnosis, such conditions should be included in the differential diagnosis of bone lesions in the orofacial region.
