Diagnóstico diferencial inmunomorfológico de las lesiones quísticas maxilares con queratinización
2011
ResumenObjetivosLos quistes maxilares con queratinización son formas lesionales de carácter controvertido y de relevancia clínica, dada la implicación clínico-evolutiva del llamado tumor odontogénico queratoquístico (TOQ). En el presente estudio nos planteamos valorar la utilidad de las técnicas inmunohistoquímicas en la identificación de estas lesiones.Material y métodosSe analizan de forma retrospectiva las lesiones quísticas maxilares dotadas de fenómenos de queratinización interna, diagnosticadas en un mismo centro hospitalario, a lo largo de un periodo de 4 años, realizando un estudio inmunohistoquímico mediante la aplicación de un panel de cinco anticuerpos (Ki67, Bcl-2, p53, CK19, D2…
Evaluation of the primary stability in dental implants placed in low density bone with a new drilling technique, osseodensification: an in vitro study
2020
Background Primary stability is an important key determinant of implant osseointegration. We investigated approaches to improve primary implant stability using a new drilling technique termed osseodensification (OD), which was compared with the conventional under-drilling (UD) method utilized for low-density bones. Material and Methods We placed 55 conical internal connection implants in each group, in 30 low-density sections of pig tibia. The implants were placed using twist drill bits in both groups; groups Under Drilling (UD) and Osseodensification (OD) included bone sections subjected to conventional UD and OD drilling, respectively. Before placing the implants, we randomized the bone s…
Management of odontogenic infection of pulpal and periodontal origin
2007
The dental biofilm is a complex bacterial ecosystem that undergoes evolution, maturing and development, and thus leads to odontogenic infection. The infection is normally located in the tissues of the dental organ itself, and follows a chronic course of evolution. However, bacterial pathogens express virulence factors in the biofilm, and this together with changes in host immunity, may cause clinical exacerbations and spread of infection to other areas of the body. Odontogenic infection management should take into consideration the fact that therapeutic success lies in the control of the infectious aetiologic agent, using mechanical-surgical debridement and/or antimicrobial therapy. Debride…
Antibiotic susceptibility of the bacteria causing odontogenic infections
2006
Objetivos: Identificar la flora bacteriana y su susceptibilidad a varios antibióticos utilizados en infecciones odontogénicas de localización periapical y en las pericoronaritis del tercer molar inferior, para poder adaptar convenientemente el tratamiento antibiótico a las exigencias de tales infecciones, y evitar así los efectos secundarios y los sobretratamientos con antibióticos. Material y métodos: Se han seleccionado con unos criterios de inclusión y de exclusión a 64 pacientes que presentaban una infección odontogénica. Se recogieron muestras de las lesiones en condiciones de máxima asepsia, evitando la contaminación por flora saprófita bucal. Las muestras se sembraron en medios de cu…
Odontogenic deep neck space infection in a patient with hyper-IgE syndrome: A case report
2018
Hyperimmunoglobulin E syndrome is a primary immunodeficiency state that is characterized by eczema, recurrent skin and lung infections, and markedly increased levels of IgE. Odontogenic infection can spread to vital and deep structures in such immunocompromised patients. We report a case of a 19-year-old man with hyperimmunoglobulin E syndrome presenting deep neck space infection that had spread from periapical periodontitis of the lower molars. A computed tomography scan showed an area of bony destruction in the left mandible and abscess formation in the submandibular and submental spaces. The patient was successfully treated by cervical drainage, extraction of the causative teeth, and ant…
Antibiotic prescription in the treatment of odontogenic infection by health professionals: a factor to consensus
2011
Objective: To observe the attitude of dentists and family doctors in prescribing antibiotics for the treatment of dental infections. Study Design: A poll was performed to determine the differences in the prescription of antibiotics for the treatment of odontogenic infection by dentists and family doctors of the primary care department of the Catalan Health Care Service. Results: A hundred polls were distributed among family doctors, and another 100 ones among primary care dentists assigned to the Catalan Health Care Service of the Generalitat de Catalunya. Of the total of questionnaires distributed, 63 were retuned and answered from dentists and 71 from family doctors. Eighty-one percent of…
Accuracy of computer-aided image analysis in the diagnosis of odontogenic cysts: A systematic review
2020
Background This study aimed to search for scientific evidence concerning the accuracy of computer-assisted analysis for diagnosing odontogenic cysts. Material and Methods A systematic review was conducted according to the PRISMA statements and considering eleven databases, including the grey literature. Protocol was registered in PROSPERO (CRD 42020189349). The PECO strategy was used to define the eligibility criteria and only studies involving diagnostic accuracy were included. Their risk of bias was investigated using the Joanna Briggs Institute Critical Appraisal tool. Results Out of 437 identified citations, five papers, published between 2006 and 2019, fulfilled the criteria and were i…
Prosthetic rehabilitation with dental implants after treatment of a keratocystic odontogenic tumor. Case report
2011
Keratocystic odontogenic tumor (KCOT), formerly known as the odontogenic keratocyst (OKC) is a benign intraosseous lesion, characterized by invasive growth and high rate of recurrences. Although it is not frequently seen, KCOT may be associated with unerupted teeth and without relevant histopathological examinations, might be mistaken with dentigerous cyst. A 26 year-old male patient referred to our department with complaints of two months persisting painless swelling on the left side of mandible. Clinical and radiographic examinations revealed an impaction of the horizontally positioned left lower second premolar surrounded by a well-circumscribed radiolucent mass, located between the left…
Oral health effects of botulinum toxin treatment for drooling:a systematic review
2020
Background Drooling is a major morbidity in several neurological diseases. Intraglandular botulinum neurotoxin (BoNT) injections have been used to manage this condition. However, by decreasing salivary flow, BoNT injections may result in an increased risk of caries and other oral adverse effects. In this study, we aimed to assess whether, in patients with drooling, intraglandular BoNT injections are associated with increased dental caries development, modifications on salivary composition (oral pH, buffering capacity and osmolality) and cariogenic bacterial load. Material and Methods We performed a systematic review, searching PubMed, CENTRAL, Web of Science, and Scopus for all experimental…
