Update on the use of corticosteroids in third molar surgery: systematic review of the literature.

OBJECTIVES: Third molar extraction produces inflammation, pain, and trismus, and different pharmacologic therapies have been evaluated for the minimization of postsurgical symptoms. The most frequently prescribed drugs are nonsteroidal anti-inflammatories, followed by steroids and opiates. MATERIAL AND METHODS: A systematic search of the literature was carried out in PubMed, Scopus, MEDLINE, and Cochrane using steroid and third molar as key words. RESULTS: The most relevant randomized controlled trials and meta-analyses (n = 28) were selected from among 72 articles. CONCLUSIONS: Administration of corticosteroids improves the postoperative experience of patients and has a significant impact on trismus and inflammation. Greater effects appear to be achieved by using the parenteral route and by administering the corticosteroid before the surgery.

Dental implant stability is influenced by implant diameter and localization and by the use of plasma rich in growth factors.

PURPOSE: The objective was to analyze the factors that influence the stability of dental implants at 12 weeks after implant placement as measured by resonance frequency analysis using the Osstell system. MATERIALS AND METHODS: This prospective clinical study was performed in 235 implants placed in 93 patients at the Oral Surgery and Implantology Clinic of the University of Granada. The gathered predictor variables were grouped into patient variables, implant variables, operative variables, and baseline implant stability quotient (ISQ). All variables were analyzed in a multivariate model to determine their influence on the ISQ score at 12 weeks after implant insertion (outcome variable). SUDAAN software was used for clustered sampling (multiple implants in patients). RESULTS: Two hundred thirty-five dental implants were placed in 47 men (50.5%) and 46 women (49.5%; total, 93 patients; mean age, 52.13 ± 11.23 years; range, 27 to 76 years). No association was found between the patient variables and the ISQ values at 12 weeks. Among implant variables, worse ISQ values at 12 weeks were observed for a narrow diameter (P < .001) and maxillary implants (P = .006). Among surgical technique variables, the use of plasma rich in growth factors (P = .011) showed the best ISQ values at 12 weeks. CONCLUSIONS: The diameter and localization of implants and the application of plasma rich in growth factors influenced the stability of implants measured at 12 weeks of wound healing. Accordingly, stability was less with a narrower implant diameter and maxillary localization and greater with implants humidified with plasma rich in growth factors.

Measurement of dental implant stability by resonance frequency analysis: A review of the literature

Dental implant treatment is an excellent option for prosthetic restoration that is associated with high successrates. Implant stability is essential for a good outcome. The clinical assessment of osseointegration is based onmechanical stability rather than histological criteria, considering primary stability (absence of mobility in bonebed after implant insertion) and secondary stability (bone formation and remodelling at implant-bone interface).The aim of this study was to review the literature on Resonance Frequency Analysis (RFA) as a methodfor measuring dental implant stability. An online search of various databases was conducted on experimentaland clinical research published between 1996 and 2008. The studies reviewed demonstrate the usefulness ofRFA as a non-invasive method to assess implant stability. Further research is required to determine whetherthis system is also capable of measuring the degree of dental implant osseointegration (AU)

Impact of public preventive programmes on oral quality of life of 11 to 12-yr-old school students.

OBJECTIVES: The objective was to analyze the impact of preventive programmes on oral quality of life in school students aged 11-12 yrs. STUDY DESIGN: In the school year 1996/97, a quasi-experimental study was initiated in Granada province with four groups of students aged 6-7 yrs: Sealant + Fluoride (sealants on first permanent molars applied in the health centre for a 3-yr active programme, and fluoride varnish applied every four months for 3 yrs, n=65), Sealant (only sealants, n=80), Fluoride (only fluoride varnish, n=107) and Control group (n=59). All students were examined every 6 months at school during the 3-yr active programme and received an oral health report after each examination. At 5.5 yrs (school year 2002/03), after 2.5 yrs with no programme, students were again examined and completed a questionnaire on oral quality of life scored from -6 (minimum) to +6 (maximum). RESULTS: Oral quality of life values (+/- standard deviation) were: 3.31+/-0.30 (Sealant + Fluoride), 3.11+/-0.27 (Sealant), 3.18+/-0.23 (Fluoride) and 2.95+/-0.32 (Control), with no statistically significant differences among them. CONCLUSIONS: Fissure sealant and fluoride varnish programmes had no significant influence on oral quality of life after a 5.5- yr follow-up (3 yrs of active programme plus 2.5 yrs of discontinuation).

Juvenile ossifying fibroma: a case study.

We present the case of an 8-year-old patient with a juvenile ossifying fibroma in the right mandibular angle and a radicular cyst in the left mandibular angle, which produced a major swelling at the level of the mandibular angles and prevented the correct eruption of the lower first molars. After the clinical and radiological (panoramic X-ray and dental scan of the mandible), the corresponding surgical treatment (cystectomy and remodelling) and histopathological study were carried out. Although juvenile ossifying fibroma is an uncommon clinical entity, its aggressive local behaviour and high recurrence rate mean that it is important to make an early diagnosis, apply the appropriate treatment and, especially, follow the patient up over the long term.

Fibroma óseo juvenil: a propósito de un caso clinic / Juvenile ossifying fibroma: a case study

Se presenta el caso clínico de un paciente de 8 años de edad con un fibroma osificante juvenil en el ángulo mandibular derecho y un quiste radicular en el ángulo mandibular izquierdo, los cuales producían un importante abombamiento a nivel de los ángulos mandibulares e impedían la correcta erupción de los primeros molares inferiores. Tras el estudio clínico y radiológico ( Ortopantomografía y Scan dental del maxilar inferior), se llevó a cabo el correspondiente tratamiento quirúrgico (quistectomía y remodelación de los mismos) y el estudio histopatológico. Aunque el fibroma óseo juvenil es una entidad clínica poco frecuente, debido al comportamiento local agresivo y a la recidiva que tiene, es importante realizar un diagnóstico precoz, un tratamiento adecuado y, sobre todo, un seguimiento del paciente a lo largo del tiempo (AU)

Cirugía periapical de 29 dientes. Comparación entre técnica convencional, microsierra y uso de ultrasonidos / Peripical surgery of 29 teeth. A comparison of convencional techique, microsaw and ultrasound

Objetivos: Evaluar clínica y radiológicamente los resultados obtenidos en cirugía periapical mediante la utilización de diferentes técnicas. Material y Métodos: Se han analizado 29 dientes unirradiculares (en 29 pacientes) que presentaban patología periapical tras un tratamiento endodóntico correcto. Se han formado tres grupos: A) 10 pacientes en los que la osteotomía, apicectomía y preparación cavitaria se hicieron con instrumental rotatorio; B) 10 pacientes a los que se les realizó la osteotomía y la resección apical con instrumental rotatorio, y la preparación retrógrada con ultrasonidos; y C) con 9 pacientes en los que se utilizó la microsierra para la osteotomía y los ultrasonidos para preparar la cavidad en la raíz. Todos los casos fueron obturados con IRMO. Se realizaron controles clínicos y radiográficos a los 10 días, 1 mes, 6 meses y 1 año. Resultados: Al término del estudio, se obtuvo un éxito clínico en 17 pacientes (58,6 por ciento), que no presentaron sintomatología, y 16 (55,2 por ciento) mostraron una imagen radiográfica con regeneración ósea completa (curación completa). El éxito clínico al año fue para el grupo B del 70 por ciento, en el grupo C del 66,7 por ciento y del 40 por ciento en el grupo A. La completa curación radiográfica tuvo lugar en un 30 por ciento en el grupo A, en el 60 por ciento en el B y en el 77,8 por ciento en el C. El grupo A presentó 3 fracasos y 2 en el C, no existió ningún fracaso en el grupo B. Conclusiones: La técnica más satisfactoria fue cuando se usaron los ultrasonidos para la preparación de la cavidad (AU)

Influencia de programas públicos de salud oral en los esolares sobre la demanda privada de Odontología Restauradora / Influence of public oral health schoolchildren programmes on private restorative dentistry demand

lntroducción:(fundamento y objetivo): El objetivo es analizar la influencia de algunos programas públicos odontológicos sobre la demanda de odontología restauradora privada. Métodos: En el curso 96/97 se inició un ensayo de campo en Granada, con cuatro grupos ce escolares de 6-7 anos de edad Sellador (aplicados en el Centro de Salud, n=121), Sellador+Flúor (+ barniz de flúor en los colegios, n=119), Flúor (n=137) y Con-trol (n-95). Todos fueron explorados al inicio, y a los 6 meses. Se analiza el incremento de odontología restauradora privada, a través del índice cie restauración (dientes obturados del total de dientes cariados + obturados). Resultados y conclusiones El índice de restauración aumentó significativamente en los cuatro grupos. El incremento medio (- desviación estándar) de obturaciones 2s mayor en los grupos Sellador (0.54-1 1 57) y Sellador+Flúor (0.55+-1.27), que en los grupos Flúor (0.23 0.99) y Control (0.19ñ0 80), no habiendo diferencias significativas de incremento entre los grupos Sellador +Flúor y Sellador, ni entre Flúor y Control. Se concluye que un programa de selladores desde un centro de salud produce un incremento de la demanda de odontología restauradora, pero no un programa de flúor tópico profesional (barniz) realizado en el colegio (AU)

Neurilemomas en el territorio maxilofacial. A propósito de tres casos clinicos / Maxillofacial neurilemmomas, A report of three cases

Los neurilemomas son tumores de origen nervioso de rara presentación en la región cervicofacial y, sobre todo, en la cavidad oral. Para su diagnóstico es necesario realizar un estudio histopatológico, ya que su aspecto clínico puede confundirse con otros tipos de lesiones benignas comunes. Se presentan tres casos de neurilemomas: dos de localización intraoral y uno extraoral. En los tres pacientes se realizó la técnica quirúrgica de la biopsia-extirpación, consistente en la enucleación completa de la lesion. Se encontró en todos ellos un tumor bien circunscrito, no adherido a planos profundos, de superficie lisa y consistencia gomosa. Asi mismo, se presentan los resultados de los exámenes histopatológicos, que muestran la presencia de patrones celulares Antoni tipo A y tipo B, patognomónicos de los schwannomas (AU)
