ABSTRACT

Background: Surgical extraction of the lower third molar (LTM) may trigger neurosensory injury of the inferioralveolar nerve, making extraction a real challenge. This study set out to assess whether is it possible to predictneurosensory alterations from preoperative imaging.Material and Methods: A total of 99 patients underwent 124 impacted lower third molar (ILTM) surgeries. Priorto surgery, panoramic and CBCT images were evaluated in an attempt to predict a neurosensory disturbance.Preoperative data (ILTM position, panoramic radiograph signs, inferior alveolar nerve (IAN) location and its con-tact with the ILTM roots) and intra/postoperative findings (extraction difficulty and sensitivity alterations) wererecorded. Descriptive and bivariate data analysis was performed. Statistical comparison applied the chi-squaretest, Fisher test, and one-way ANOVA test. Statistical significance was established with a confidence interval (CI)of 95%.Results: In 4.03% of cases, patients experienced neurosensory alterations. Of 124 ILTM positions in panoramicradiographs, 76 cases were considered to exhibit a potential neurosensory risk as they presented two or more typesof superimposed relationships between ILTM and mandibular canal. Of these, alterations were reported in onlythree cases (3.95%). Of the 48 remaining ILTM images presenting only one sign, neurosensory alterations wereobserved in two cases (4.17%). No permanent alterations were recorded in any of the five cases observed.Conclusions: Within the limitations of the present study, prediction of neurosensory alterations prior to ILTMextraction by means of preoperative imaging did not show a significant statistical correlation with post-surgicalincidence. Nevertheless, interruption of the canal´s white line (ICWL) or a diversion of the canal (DC) may predictan increased risk of IAN injury.(AU)

Elobjetivo de esta revisión es comparar, según la literatura, la incidencia de alveolitisen mujeres en tratamiento con anticonceptivos orales respecto a las que no lostoman y respecto a los hombres.Métodos: Se realizó una búsqueda bibliográfica en las bases de datos PubMed/Medline, Science Direct, GoogleScholar y Scopus y se incluyeron artículos en inglés y en español relacionadoscon el tema a tratar. Las palabras claveutilizadas fueron: “alveolar osteitis” OR “fibrinolytic alveolitis” OR “localized osteomyelitis” OR “delayed extraction woundhealing” AND “contraceptives” OR “OC”OR “contraceptive pill”. Se incluyeron estudios sobre exodoncias en pacientes entratamiento con anticonceptivos o sin anticonceptivos o varones, según los gruposde control que se han propuesto estudiar,que registrasen casos de alveolitis.Resultados: Se observó una mayor incidencia media de alveolitis post extracciónen las pacientes en tratamiento con anticonceptivos (18,52%), respecto a otraspacientes que no lo estaban (6,78%) yrespecto a la población de género masculino (6,4%)...(AU)


Introduction: Alveolitis is a complicationafter dental extraction which courses withintense pain, trismus, and halitosis. This complication is associated with smoking,oral hygiene, not following post-extraction rules or the age and gender of the patient. However, other potential causes could trigger this process, such as the menstrual cycle in the case of female patients or the fact that they are under treatment with oral contraceptives. The objective of this review was to compare the incidence of alveolitis among patients treated with oral contraceptives with those who do not take them. Methods: A bibliographic search was carried out in the databases PubMed/Medline, Science Direct, Google Scholar and Scopus and articles in English and Spanish related to the topic were included.Keywords used were: “alveolar osteitis ”OR “fibrinolytic alveolitis” OR “localized osteomyelitis” OR “delayed extraction wound healing” AND “contraceptives”OR “OC” OR “contraceptive pill”. Studies on exodontia in patients treated with contraceptives with registered cases of alveolitis were included.Results: A higher mean incidence of alveolitis was observed in patients treated with contraceptives (18.52%),with respect to other patients who were not (6.78%) and with respect to male population (6.4%)...(AU)

ABSTRACT

Background: The diagnosis of oral melanotic lesions is, more often than not, challenging in the clinical practice due to the fact that there are several reasons which may cause an increase in pigmentation on localized or generalized areas. Among these, medication stands out. Material and Methods: In this work, we have carried out a review in the reference pharma database: Micromedex® followed by a review of the scientific published literature to analyse coincidences and possible discrepancies. Results: Our findings show that there are several prescription drugs that can cause pigmented lesions in the oral mucosa. This must be known by clinicians in order to properly diagnose pigmented lesions. We have identified a set of 21 medicaments which cause these lesions, some of which are used frequently in the clinic, such as Metronidazole, Amitriptyline, conjugated oestrogens and Chlorhexidine gluconate. We also found discrepancies with the data published in specialized literature, some of which wasn’t reflected in the Summary of Product Characteristics. Conclusions: Our work highlights the importance of the proper communication of adverse drug reactions (ADR) by health professionals in order to provide thorough and accurate information and diagnosis.(AU)

ABSTRACT

OBJECTIVES: To determine the survival of intentional autotransplantation of developing teeth. MATERIAL AND METHODS: An electronic search was carried out in the MEDLINE database, Web of Science, and Cochrane Library. The criteria used are the ones described in the PRISMA Declaration. The following MeSH terms were used: ("tooth" [MeSH Terms] OR "tooth" [All Fields]) AND ("transplantation, autologous" [MeSH Terms] OR ("transplantation" [All Fields] AND "autologous" [All Fields]) OR "autologous transplantation" [All Fields] OR "autotransplantation" [All Fields]) AND ("humans" [MeSH Terms]. Randomised clinical trials and prospective and retrospective clinical studies were included. RESULTS: The meta-analytic study of overall survival included a total of 14 studies, yielding an overall survival rate of 97.9%. In studies with 1-year follow-ups, survival was 98%. The resulting 2-year follow-up rate was 97%, while the 5- and 10-year survival rates were 95.9% and 96.9%, respectively. CONCLUSIONS: The autotransplantation technique performed in a single-phase and on teeth that have not completed their development is a predictable technique, with a described survival rate at a 2-year follow-up of more than 97%. CLINICAL RELEVANCE: The technique of dental autotransplantation is considered an important resource for the resolution and rehabilitation of tooth loss in patients, especially in those who are still in a growth period. Moreover, this technique has a low complication rate and a 10-year survival rate of 96.9%. It should therefore be considered a safe and reliable procedure.

ABSTRACT

Introducción: Existen numerosos procedimientos para conseguir un lecho óseo adecuado para colocar implantes tras la pérdida de dientes naturales. En los últimos años se han propuesto técnicas para la preservación del lecho tras la extracción dental. Los injertos de dentina autóloga ofrecen un sustrato conveniente con propiedades osteoinductivas y osteogénicas óptimas para la regeneración alveolar. Objetivo: Se presenta un caso clínico de un paciente rehabilitado mediante un tratamiento quirúrgico y prostodóntico, y una actualización de la bibliografía en relación con los injertos de dentina autóloga. Caso clínico: Varón de 64 años sin antecedentes médicos ni hábitos patológicos, que presenta desgastes severos, inestabilidad oclusal y problemas estéticos. Se realiza una rehabilitación integral del paciente combinando una técnica quirúrgica de preservación alveolar con injerto de dentina autóloga, tras la cual se procede a la colocación de implantes, con un tratamiento protésico de coronas de zirconio, incrustaciones de disilicato de litio y reconstrucciones de composite. El tratamiento protésico se realiza en dos fases, pasando por una fase de provisionalización previa a la colocación de las restauraciones definitivas, empleando el flujo digital. A los 6 meses el paciente se encuentra satisfecho y con una función y estética óptima. Conclusiones: El injerto de dentina autóloga parece una alternativa eficaz y predecible como material de regeneración alveolar. Combinando esta técnica de preservación con una planificación digital, se puede maximizar el resultado del tratamiento rehabilitador, consiguiendo una mayor satisfacción del paciente. (AU)


Introduction: There are multiple procedures to achieve an adequate bone site for implant placement after teeth loss. In the last years, numerous techniques have been proposed for alveolar preservation. Dentin autologous grafts offer a convenient substrate with osteoinductive and osteogenic properties, which are optimum for alveolar regeneration. Objective: In this article, a clinical case of a patient rehabilitated by surgical and prosthodontic treatment, and a review of the literature regarding autologous dentin grafts is presented. Case report: 64 years old male, with no medical records or parafunctional habits, presents severe wear, occlusal instability and aesthetic problems. An integral rehabilitation is performed combining a surgical preservation technique with autologous dentin graft, after which the placement of the implants takes place, and a prosthodontic treatment with zirconium crowns, lithium disilicate inlays and composite restorations. The prosthodontic treatment is accomplished in two phases, going through a provisionalization phase previous to the placement of the definitive restorations, and digital workflow is used. 6 months later, the patient is satisfied, and function and aesthetic are optimum. Conclusions: Dentin autologous graft offers a predictable and effective alternative as a material for alveolar regeneration. Combining this preservation technique, with a good digital planification, results can be maximized and satisfaction for the patient can be increased. (AU)

ABSTRACT

Introducción: La participación en el rugby se ha visto incrementada con el paso de los años, especialmente en países donde la práctica de este deporte no era habitual, lo que ha arrojado como consecuencia un aumento en la incidencia de lesiones, dada la naturaleza de alto impacto del mismo. Diversos estudios epidemiológicos han evaluado la incidencia de traumatismos bucodentales como consecuencia de accidentes deportivos, en los que se hace referencia a las fracturas dentarias como aquellas más comúnmente producidas dentro de la práctica de este tipo de deportes. Descripción del caso clínico: Se presenta el caso clínico de un paciente varón de 18 años de edad, sin antecedentes médicos de interés, remitido al servicio de Cirugía Bucal del Hospital Viamed Virgen de la Paloma de Madrid, quién presentaba una lesión de tejidos blandos, además de luxación palatina del sector dentario anterosuperior, como consecuencia de un traumatismo durante un partido de rugby, para el cual se prescribió tratamiento farmacológico combinado con una ferulización, permitiéndose así la cicatrización espontánea de los tejidos. Discusión y conclusiones: Se observa una alta incidencia de lesiones producidas durante la práctica del rugby debido al escaso equipamiento protector usado por los jugadores, donde la cara y sus tejidos blandos constituyen las zonas con mayor frecuencia de afectación, pudiendo considerarse como el deporte de alto impacto con mayor prevalencia de lesiones de cabeza y cuello. (AU)


Introduction: Participation in rugby has increased over the years, especially in countries where the practice of this sport was not common, which has resulted in an increase in the incidence of injuries given its high-impact nature. Various epidemiological studies have evaluated the incidence of oral trauma as a result of sports accidents, in which dental fractures are referred to as those most commonly produced within the practice of this type of sports. Description of the clinical case: We present the clinical case of an 18-yearold male patient, with no relevant medical history, referred to the Oral Surgery Service of the Virgen de la Paloma Viamed Hospital in Madrid, who presented a soft tissue lesion in addition to a palatal dislocation of the dental sector anterosuperior as a result of trauma during a rugby match, for which drug treatment combined with splinting was prescribed, thus allowing spontaneous tissue healing. Discussion and conclusions: A high incidence of injuries produced during rugby practice is observed due to the scarce protective equipment used by the players, where the face and its soft tissues constitute the areas with the highest frequency of affectation and can be considered as the high-impact sport with the highest prevalence of head and neck injuries.

ABSTRACT

Introducción: El Pénfigo Vulgar (PV) es una enfermedad de origen autoinmune caracterizada por causar ampollas intraepidérmicas en piel y mucosas, como consecuencia de la agresión de autoanticuerpos hacia varios tipos de proteínas desmosómicas. El elemento eruptivo primordial es la ampolla, que puede presentarse de manera individual o en coalescencia con la consecuente formación de placas erosivo-costrosas. En el 90% de los casos las lesiones afectan a la mucosa oral, mientras que en el 50-70% de los mismos constituyen la primera manifestación de la enfermedad. Objetivo: Se presenta un caso clínico de PV y una revisión bibliográfica actualizada, con el objetivo de analizar sus factores etiológicos y sus opciones terapéuticas. Caso clínico: Se presenta el caso de un paciente varón, de 71 años, fumador, con condición prediabética y síndrome de Guillain Barré remitido al Servicio de Cirugía Bucal e Implantología del Hospital Virgen de la Paloma de Madrid con un cuadro clínico caracterizado por infección oral y pérdida de peso. Una vez confirmado el diagnóstico de PV mucoso mediante examen histopatológico, se estableció una terapia con corticoides sistémicos obteniendo una remisión casi completa de las lesiones. Tras varias semanas de tratamiento su dermatólogo decidió suspender los corticoides para llevar a cabo, sin éxito, una terapia sustitutiva con inmunosupresores. La recidiva de las lesiones, unida a los efectos adversos causados por la nueva terapia, obligó a reconsiderar la suministración de corticoides con una resolución positiva de la enfermedad. (AU)


Introduction: Pemphigus Vulgaris is an autoimmune disease characterized by causing intraepidermal blisters on the skin and mucosa, as a consequence of the aggression of autoantibodies towards various types of desmosomal proteins. The primary eruptive element is the blister, which can appear in coalescence with the consequent formation of erosive-crusted plaques. In 90% of cases lesions affect the oral mucosa, while in 50-70% they are the first manifestation of the disease. Objective: We aim to report a case of Pemphigus Vulgaris and an updated literature review to analyse its etiological factors and treatment options. Clinical case: We present the case of a 71-year-old male patient, smoker, with prediabetic condition and sindrome Guillain Barré referred to the Oral Surgery and Implantology Service of the Virgen de la Paloma Hospital in Madrid with a clinical picture characterized by oral infection. Once the diagnosis of mucosal PV was confirmed, a systemic corticosteroid therapy was established, obtaining almost complete remission of the lesions. After several weeks of treatment, his dermatologist decided to suspend the corticosteroids to carry out unsuccessful immunosuppressant replacement therapy. The recurrence of the lesions, together with the adverse effects caused by the new therapy, forced the reconsideration of the supply of corticosteroids with a positive resolution of the disease.

ABSTRACT

La utilización de injertos intraorales en bloque es una alternativa de tratamiento válida para la regeneración en anchura de defectos óseos maxilares y mandibulares. Sin embargo, actualmente no hay consenso entre los diferentes autores en la elección del mejor tipo de bloque intraoral a utilizar. Por ende, esta puesta al día busca comparar la ganancia ósea, la tasa de complicaciones postoperatorias y el éxito del injerto entre bloques autólogos de rama mandibular y mentón. La ganancia ósea alcanzada es similar en ambos bloques. No obstante, se podría deducir una mayor ganancia al utilizar bloques de la rama mandibular cuando son evaluados mediante CBCT. Además, la tasa de reabsorción ósea fue menor con los injertos de rama. La supervivencia de los implantes es equiparable con ambos tipos de injertos. Las complicaciones que tienen lugar, en orden de frecuencia, son las alteraciones sensoriales, las necrosis pulpares, dehiscencias y hemorragias; apareciendo con mayor frecuencia en los bloques de mentón. Además, el periodo de recuperación en las zonas de rama mandibular es más lento. De este modo, a la hora de la elección parece razonable individualizar el caso y tener en consideración aspectos como la morbilidad y el acceso a la zona donante. (AU)


The use of intraoral block grafts is a valid treatment alternative for the regeneration of maxillary and mandibular horizontal bone defects. However, there is currently no consensus among different authors on the choice of the best type of intraoral bone block to use. Therefore, this update seeks to compare bone gain, post-operative complication rate and grafting success between autologous mandibular ramus and chin bone block grafts. The bone gain achieved is similar in both block grafts. However, a higher gain can be observed by CBCT when using mandibular ramus blocks. In addition, the rate of bone resorption is lower with ramus grafts. Implant survival is comparable in both types of grafts. The complications that occur, in order of frequency, are sensory alterations, pulp necrosis, dehiscence and bleeding, appearing more frequently in chin blocks. In addition, the recovery period in the mandibular ramus areas is slower. Thus, when choosing, it seems reasonable to individualize the case and take into consideration aspects such as morbidity and access to the donor area. (AU)

ABSTRACT

Introducción: El empleo de dientes autógenos, como material de injerto, es una opción terapéutica actual en casos de regeneración ósea. Su obtención se ha facilitado con la introducción de dispositivos capaces de procesar los dientes. El objetivo de este trabajo es realizar, a propósito de un caso clínico, una revisión de la literatura sobre el uso de dientes autólogos como material de injerto óseo y los dispositivos para su procesamiento. Caso clínico: Paciente varón de 18 años que acude a consulta presentando un cordal inferior retenido. El diagnóstico determinó la necesidad de extraer el diente y se informó al paciente de la posibilidad de utilizarlo como material de regeneración ósea. Tras la exodoncia, el diente procesado con el dispositivo Tooth Transformer(R) (Imbiodent), fue utilizado como material de injerto autólogo. El postoperatorio no presentó ninguna complicación y la evaluación radiográfica, tras 8 días y tras 10 semanas, mostró una evolución favorable del tratamiento. Discusión: La dentina desmineralizada es un material orgánico cuyo potencial reside en los factores de crecimiento que contiene para estimular la formación y reparación ósea. No obstante, no existe consenso sobre el grado de desmineralización o tamaño de partícula ideal. La reciente introducción de dispositivos, capaces de procesar dientes, facilita la obtención de un material de injerto dental para su uso en terapias de regeneración ósea. Conclusión: El uso de dientes autólogos constituye una alternativa prometedora en el campo de los injertos óseos. La técnica de transformación del diente es sencilla con el empleo de los dispositivos actuales


Introduction: The use of autogenous teeth, as graft material, is a current therapeutic option in cases of bone regeneration. Its obtention has been facilitated by the introduction of devices capable of processing teeth. The aim of this article is to perform, based on a clinical case, a review of the literature about the use of autologous teeth as bone graft material and the devices for its processing. Clinical case: Male patient, 18 years of age, who comes to the dental office presenting a lower wisdom retained. Extraction of the tooth was determined by diagnosis and the patient was informed about the possibility of using it as bone regeneration material. After the extraction, the tooth was processed by the Tooth Transformer(R) (Imbiodent) device and was used as autologous graft material. No postoperative complications were presented and the radiographic evaluation, at 8 days and 10 weeks, showed a favorable evolution of the treatment. Discusion: Demineralized dentin is a organic material whose potential relies in the growth factors it contains to stimulate bone formation and repair. However, there is no consensus on the degree of demineralization or the ideal particle size. The recent introduction of devices, capable of processing teeth, enables the obtention of a dental graft material for bone regeneration therapies. Conclusion: The use of autologous teeth is a promising alternative in the bonev grafts field. The technique of tooth transformation is simple with the use of the current devices

ABSTRACT

Las extracciones dentarias producen una pérdida ósea en sentido horizontal y vertical, que conllevan alteraciones funcionales para los pacientes, y dificultan la colocación de implantes dentales para los profesionales. Para minimizar esta pérdida ósea, se utilizan diferentes materiales de injerto, entre los cuales destaca el injerto autógeno, por cumplir las características de osteogénesis, osteoconducción y osteoinducción. En el año 2010 se describe por primera vez la utilización de dentina como material de injerto autógeno, demostrando que este material puede ser una alternativa terapéutica al resto de materiales de injerto, al permitir la osteoconducción y la osteoinducción, y mostrar la formación de hueso nuevo en un 46-87% del área con injerto de dentina autógena, 3 meses después de su utilización. La última revisión sistemática publicada en el año 2018, concluyó que los implantes colocados en áreas regeneradas en zonas en las que se empleó dentina como material de injerto, presentaron tasas de supervivencia del 97,7% después de 1 año de seguimiento, sugiriendo este nuevo material como una alternativa con resultados prometedores, aunque son necesarios más estudios al respecto


Subsequent to tooth extraction, a reduction of the length and width of alveolar ridge can be observed. It causes functional alterations to patiens, and problems to proper insertion of dental implants. In order to prevent this bone atrophy, different graft materials can be used, being considered autogenous graft the best because allows osteogenesis, osteoconduction and osteoinduction. In 2010 it was first published the use of autogenous dentine as a graft material, showing it could be an ideal graft material, as a material with excellent osteoconduction and osteoinduction. Besides, this graft material is slowly absorbed and replaced by new bone, in 46-87% of the áreas grafted with dentine, 3 months after regeneration. Last systematic review published in 2018 concluded dental implants inserted in regenerated areas with autogenous dentine had survival rates of 97,7% for over a year follow-up, so this new material is considered an alternative with good results, but there are necessary more studies with long term follow-up

ABSTRACT

Langerhans cell histiocytosis (LCH) is a rare disease, of unknown pathogenesis, characterized by intense and abnormal proliferation of bone marrow-derived histiocytes (Langerhans cells). It can present both local and systemic manifestations involving bone, skin and mucosal tissue, and internal organs. Three basic clinical forms develop: Letterer-Siwe disease (subacute or acute disseminated form), Hand-Schüller-Christian disease (disseminated chronic form) and eosinophilic granuloma (localized chronic form). LCH may manifest orally with single or multiple lesions of the alveolar or basal bone, ulcerated mucosal lesions accompanied by adenopathies and/or periodontal lesions, presenting gingival inflammation, bleeding, recession, necrosis, odontalgia, dental hypermobility and premature loss of teeth. The principal differential diagnoses include advanced periodontal disease or a periapical process of dental or periodontal origin. The odontologist plays a vital role in the diagnosis and multidisciplinary treatment of such patients, by performing routine examinations for periodic follow-up of the disease and its possible oral manifestations, bearing in mind that these may be the first or only signs of LCH (AU)

ABSTRACT

Los continuos avances tecnológicos y la incorporación de técnicas no basadas en los rayos X han hecho que el concepto básico de la radiografía haya sufrido importantes modificaciones, aceptándose como más adecuada el término Diagnóstico por Imagen. La aplicación de la informática, con sus espectaculares resultados, permite obtener imágenes radiográficas sin película y el desarrollo de técnicas como la TC o la RM. Los programas informáticos de planificación quirúrgica han demostrado su potencial. Las redes de comunicación facilitan la transmisión de datos a distancia, pudiendo hablarse de telediagnóstico, y los sistemas de archivo permiten el acceso inmediato a la información almacenada (AU)


The continous technological advances an the techniques incorporation not based in X rays have made that the classic concept of radiology changed suffering important modifications, accepting the most suitable the meaning of diagnostic by image. The application of informatics, with their spectacular results, allows to obtain radiographic images without film and the development of the TC or RM techniques. The informatics programs of surgical planning have proved their potential. The communication nets makes easy the transmission of facts talking about telediagnostic and the archive system permits the immediate access to the stored information (AU)

ABSTRACT

Los quistes de los maxilares constituyen un grupo de procesos patológicos frecuentes en el área maxilofacial. Comprenden diversas entidades siendo los más habituales los quistes radiculares (de origen inflamatorio) y los dentígeros o foliculares (del desarrollo), relacionados con un diente retenido. Desde el punto de vista clínico, su crecimiento es lento y suelen ser asintomáticos durante mucho tiempo, por lo que en su detección juegan un papel fundamental las técnicas radiográficas. El objetivo del presente trabajo es valorar la utilidad de los diversos procedimientos de diagnóstico por imagen disponibles en la actualidad para valorar estos procesos, así como analizar las distintas alternativas terapéuticas propuestas, tratando de establecer las principales ventajas e incovenientes de cada una de ellas. Además, se ha dedicado una consideración especial al tratamiento quirúrgico del queratoquiste odontogénico, debido a su comportamiento local, potencialmente agresivo, y a su alta tendencia a la recidiva (AU)


Jaw cysts contitute a group pf frequente pathological proceses in the maxilofacial area. They include different entities and the most commonly encountered are radicualar cysts (inflammatory origin) and follicular or dentigerous cysts (developmental cysts), which are related to an impacted tooth. From a clinical point of view, they show a slow growth speed and are typically asymptomatic for a long time, and therefore the radiographic techniques play a key role in their diagnosis. The purpose of this paper is to evaluate the usefulness of the different available imaging diagnostic procedures in the study of these processes, as well as annalize the various proposed terapeutical alternatives, trying to conclude advantages and unconvenients of each one of them. Additionally, this study dedicates a particular consideration to the surgical treatment of the odontogenic keratocyst, due to its potentially aggressive local behaviour and its tendency to recur (AU)
