    Background: Immediate implant placement in extraction sockets with active infection remains a debated topic in implant dentistry. Traditionally, the presence of periapical or periodontal infection has been considered acontraindication due to concerns about residual contamination, impaired osseointegration, and compromised esthetic results. However, recent evidence suggests that with meticulous decontamination and appropriate case selection, successful outcomes are achievable even in infected sites.Objective: This scoping review aims to explore the available scientific literature reporting on the survival rates, esthetic outcomes, and complication profiles associated with immediate implant placement in infected extraction sites. The review also analyzes the decontamination protocols used to enable safe placement in these challenging scenarios.Methods: Following PRISMA-ScR guidelines, a systematic search was conducted using PubMed to identify human clinical studies evaluating immediate implant placement into infected sites with at least 12 months of follow-up. Studies eligible for inclusion reported on at least one of the following outcomes: implant survival, esthetic results (such as Pink Esthetic Score [PES] or White Esthetic Score [WES]), or post-operative biological and/or technical complications. Only prospective or retrospective clinical studies, randomized controlled trials, and case series (n ≥ 10) were included. Relevant data were extracted using a standardized spreadsheet and synthesized thematically.Results: Thirteen studies were included, totaling 453 implants placed in infected sockets. The reported implant survival rates ranged from 90% to 100%. Esthetic outcomes, measured through PES/WES, showed mean scores between 13.9 and 15.2 (see Table 1). The majority of studies used systemic antibiotics and mechanical debridement, while some included laser decontamination and guided bone regeneration. Complication rates were low, and esthetic outcomes were generally favorable, particularly when guided bone regeneration and soft tissue grafting were employed.Conclusions: Immediate implants in infected sites demonstrate high survival and acceptable esthetic outcomes, particularly when laser decontamination and guided bone regeneration are utilized. Proper case selection and infection control remain essential. Further randomized controlled trials with long-term follow-up and consistent outcome reporting are needed.

    <jats:p>Antecedentes: A pesar de la creciente conciencia sobre la importancia de la salud general y bucal a través de intervenciones educativas, todavía existen lagunas en la comprensión e implementación de estrategias efectivas para abordar los problemas de salud. Por tanto, es necesario evaluar el efecto de dichas intervenciones en grupos específicos de población. Objetivo: Evaluar el efecto de intervenciones educativas sobre la salud general y bucal realizadas con estudiantes del Centro Educativo Eduardo Contreras de Managua, Nicaragua. Métodos: Se realizó un estudio de diseño cuasiexperimental, que se centró en evaluar conocimientos sobre salud general y bucal a través de un cuestionario y habilidades de higiene bucal a través del índice O'Leary de los estudiantes del Centro Educativo Eduardo Contreras del Residencial Las Colinas, Managua. Las evaluaciones se realizaron antes y después de la intervención educativa. Resultados: Participaron en el estudio 174 estudiantes. Los puntajes promedio de conocimientos de los estudiantes sobre salud general y bucal antes y después de la intervención educativa fueron de 9,66 y 10,76 puntos, respectivamente (p &lt; 0,001). El promedio del índice de O'Leary antes y después de la intervención fue de 28,28 % y 12,98 %, respectivamente, con una diferencia de 15,3 % (p &lt; 0,001). Conclusiones: Los conocimientos aumentaron y la placa dental disminuyó después de implementar las intervenciones educativas entre los estudiantes del Centro Educativo Eduardo Contreras que participaron en el estudio. Los hallazgos sugirieron que las intervenciones fueron exitosas.</jats:p>
