INTRODUCCIÓN: el propósito del presente estudio (primera fase) fue evaluar clínica y radiográficamente la oseointegración de implantes con regeneración ósea por medio de plasma rico en plaquetas (PRP) y hueso liofilizado, colocados en pacientes con pérdida dentoalveolar por trauma en el sector anterior, durante las primeras etapas de cicatrización de tejidos blandos; atendidos en el Hospital Universitario San Vicente de Paúl (HUSVP) de la ciudad de Medellín, Colombia. MÉTODOS: se colocaron quince implantes en seis pacientes que sufrieron pérdida dental por trauma en la zona anterior superior e inferior. La colocación de los implantes se realizó entre los ocho a veinte días posteriores al trauma, los cuales se dejaron sumergidos cuatro meses en la mandíbula y seis meses en el maxilar superior. En la segunda fase quirúrgica se realizó una evaluación clínica y radiográfica para determinar la oseointegración. RESULTADOS: el porcentaje de oseointegración fue 93,3% (catorce implantes). Un implante falló (6,7%) y presentó movilidad sin signos de infección o radiolucidez en la radiografía periapical, lo que sugiere que la falla pudo ocurrir por poca cantidad ósea o trauma quirúrgico. CONCLUSIÓN: el presente estudio mostró que el porcentaje de oseointegración en pacientes con trauma dentoalveolar fue bueno con la utilización del PRP según el protocolo utilizado.INTRODUCTION: the aim of the present study was to evaluate clinically and radiographically the osseointegration of implants with bone regeneration by platelet rich plasma (PRP) and freeze-dried bone, placed in patients with dentoalveolar loss by trauma in the anterior region, during the firsts stages of soft tissue healing, treated at the Hospital Universitario San Vicente de Paúl (Medellín-Colombia). METHODS: 15 implants were placed in six patients who suffered tooth loss due to trauma in the anterior maxillary and mandible area. The placement of the implants was performed between eight to twenty days after trauma, and they were submerged four months in the mandible and six months in the maxilla. A clinical and radiographic evaluation was done at the second-stage surgery to determine osseointegration. RESULTS: osseointegration percentage was 93.3% (14 implants). An implant failed (6.7%) and showed mobility without any infection signs or radiolucency, which suggests that failure, could be the result of surgical trauma. CONCLUSIONS: the present study showed that osseointegration percentage in patients with dentoalveolar trauma was good with the utilization of PRP according to the present protocol.

The objective of this study is to present a descriptive and retrospective analysis of the behavior of trauma to the craniofacial complex produced by firearms in patients that consulted the Maxillofacial Surgery and Estomatologic Service of the San Vicente de Paul University Hospital (HUSVP) and the School of Dentistry of the University of Antioquia between the years1998 and 2003. The parameters considered were age, sex, type of firearm used, motive of aggression, and number of impacts received. If the patients were under the effects of alcohol or psychoactive drugs at the moment of injury were also evaluated. The type of injury caused to hard and soft tissues, type of treatment performed, complications and type of healing processes were studied as well. 137 patients examined with this type of traumatism presented the following findings: the most frequent age interval reported for this type of injury was between 21 and 30 years of age with 37% of the registered cases, 89% of the patients were males, 90% of the wounds were caused by pistols, assault was the motive in 58% of the aggressions, 89% of the patients never had antecedents of this type of traumatism, 50% of the patients presented a single bullet impact and 92 of the 137 patients had never consumed alcohol or drugs. The most common treatment was closing the injury, 39% of the cases and 28% of the patients received a combination of opening and closing, 88% of the patients didn’t present an infection during treatment and a correct healing process was observed in 72% of the patients. 60% of the patients required treatments for more than ten weeks before final discharge and 70% were see within the first five days at the Maxillofacial Surgery service after being injured. The most affected anatomical regions in the midface were the malar and dentoalveolar processes and the mandibular corpus and dentoalveolar process in the mandible.

Salivary glands are symmetrical structures located near the ramus and the body of the mandible. They are the parotid glands (serous saliva), sub maxillary (predominantly serous) and sub lingual (predominantly mucous); besides numerous minor salivary glands exist on the surface of the buccal, yugal, palatine and sub lingual mucosa (300-400 approximately) that produce mucous saliva. The purpose of this literature review, is to present the difeferent infectious processes that affect the glands, the different diagnostic approaches and the treatment guidelines. The infectious disorders of the salivary glands are within the area of the responsibility of the dentistry, and every dentist must be acquainted with these disorders, with the available technologies of diagnosis and must be able to refer those cases that need the care of a specialist.
