ABSTRACT
Aims: To determine the incidence and clinical features of patients diagnosed with pilomatrixoma.Patients and Method: A retrospective analysis was made of 205 cases of pilomatrixoma diagnosed according toclinical and histological criteria, with an evaluation of the incidence, patient age at presentation, gender, lesionlocation and size, single or multiple presentation, differential diagnosis, histopathological and clinical findingsand relapses.Results: Pilomatrixoma was seen to account for 1.04% of all benign skin lesions. It tended to present in pediatricpatients almost 50% corresponding to individuals under 20 years of age with a slight male predilection(107/98). Approximately 75% of all cases presented as single lesions measuring less than 15 mm in diameter.Multiple presentations were seen in 2.43% of cases. The most frequent locations were the head and orofacialzones (particularly the parotid region), with over 50% of all cases, followed by the upper (23.9%) and lower limbs(12.7%). Only one relapse was documented following simple lesion excision.Conclusions: The frequency of pilomatrixomas was 1.04% of all benign skin lesions the lesions being predominantlylocated in the maxillofacial area. Due to the benign features of this disorder, simple removal of the lesionis considered to be the treatment of choice, and is associated with a very low relapse rate (AU)

AIMS: To determine the incidence and clinical features of patients diagnosed with pilomatrixoma.

RESULTS: Pilomatrixoma was seen to account for 1.04% of all benign skin lesions.

PURPOSE: To report on the clinical, radiological, and anatomical features of patients suffering accidental displacement of dental implants into the maxillary sinus. MATERIALS AND METHODS: A retrospective observational study of nine cases of dental implant displacement into the maxillary sinus was made. Data concerning patients' features, diagnostic criteria, and treatment performed were collected. RESULTS: Mean patient age was 56.7 years, and men predominated (6 : 3). Implant displacement was diagnosed in all cases by clinical and radiological examination. In seven patients, the implant was surgically removed without complications. Only three patients reported sinus symptoms following displacement. CONCLUSIONS: The displacement of implants into the maxillary sinus is usually related with a poor surgical planning or inadequate surgical technique. Because of the anatomy and physiology of the posterior area of the maxilla, it is essential to ensure good primary stability in order to avoid this complication. If the implant migrates into the maxillary sinus, it should be removed in order to avoid sinus pathology.

Las ventajas que la incorporación del láser ha proporcionado a la Odontología abarcan todos los ámbitos. Así, los láseres de Argón, de Nd:YAP y de Ho:YAG, tienen aplicaciones muy concretas y de gran interés tanto en el campo de la terapéutica dental como en la especialidad de cirugía bucal. Las aplicaciones principales del láser de Argón se centran en la polimerización de los materiales de restauración, en la endodoncia y dentro del ámbito de la cirugía bucal, en el corte de tejidos blandos, principalmente para la exéresis de lesiones vasculares y pigmentadas: El láser de Nd:YAP se utiliza principalmente en el campo de la endodoncia y la periodoncia, y el láser de Ho:YAG se emplea en cirugía periapical y en la cirugía artroscópica de la articulación temporomandibular (AU)
