SIMANCAS-PALLARES, M.; ARÉVALO-TOVAR, L. & MARINCOLA, M.Focal osteoporotic bone marrow defects on dental implant treated patients: a 5-year period prevalence study. Int. J. Odontostomat., 10(1):23-28, 2016. ABSTRACT:Dental implants are considered the most effective treatment for teeth absence. Nevertheless, there are some bone conditions that could affect the osseointegration process, thus affecting the clinical and radiographic success rates. One of these conditions could be the Focal Osteoporotic Bone Marrow Defects. The objective of this study was to describe the 5-year period prevalence of Focal Osteoporotic Bone Marrow Defects (FOBMD) on dental implant treated patients. descriptive retrospective study was conducted. We systematically reviewed the clinical and radiographic data of treated patients in a Dental Implant Unit since January 2010 through December 2014. Once a FOBMD case was found, a detailed questionnaire was applied to the chart looking for demographic, medical and dental characteristics (clinical and radiographic). Also in a sub-sample histological analysis was carried out. Period prevalence (PP) was estimated calculating proportions and 95 % confidence intervals. Statistical analysis was performed using Stata v. 13.2 for Windows (Stata Corp., TX., USA). FOBMD 5-yPP was 9.52 % (CI 95 %: 6.87-13.5 %). We found 42 defects in 34 patients. Within the FOBMD patients, average age was 55.4±11.9 years, 67.64 % being females. Ninety-seven percent of the defects were located in the lower jaw, 79.41 % unilateral, 69.04 % single missed teeth lesions, 71.42 % affecting molar area and 59.52 % located on the right side of the maxillae. Histological analysis revealed inflammatory cells, dystrophic calcifications, hemorrhagic material and fatty cells for all the cases. FOBMD prevalence is low, so it should be considered as a rare condition but showing an exponential growing trend over the time. With no previous epidemiological data, these findings should be considered as a caution during x-ray examinations and treatment planning, in order to avoid surgical or prosthetic complications. Local factors as previous root canal treatments should be considered when elucidating reasons for its appearance.

Introduction and Aim. In case of peri-implantitis, resective surgery is contraindicated for short and ultrashort implants, limiting the treatment options to regenerative surgery or to implant removal. This retrospective case series presents the clinical and radiographic outcomes of a surgical regenerative procedure to treat peri-implantitis around short and ultrashort implants. Materials and Methods. The study is a retrospective evaluation of patients suffering from peri-implantitis and those who underwent access flap surgery, concomitant chemical and mechanical decontamination of implant surface, and bone grafting using a self-hardening mixture of bone substitutes and biphasic calcium sulfate. No membranes were applied to cover the grafting material, and primary tension-free closure was achieved. The retrospective protocol was reviewed and approved by the Ethics Committee for Clinical Sperimentation (CESC) of Verona and Rovigo, Italy (based in the University of Verona) (Prog. 1863CESC. Date of approval: 2018-07-04). Results. 15 patients (17 implants) have been diagnosed with peri-implantitis after a mean follow-up of 24 months after loading. Implant length was between 5 and 8 mm. 8 patients (10 implants) had a history of periodontitis. At baseline, the mean PD (probing pocket dept) at the deepest site was 8.12 mm, with an average mBI (modified bleeding index) of 2.35 and a mean BD (bone defect depth) of 3.04 mm. At the 3-year follow-up, the CSR was 100%, the mean mBI was 0.88 (average reduction: −1.47), the mean PD was 3.35 mm (mean PD reduction: 4.77 mm), and the mean bone defect was reduced by 1.74 mm, with a mean bone fill of 55%. Conclusions. The results of the present case series suggest that if accurate surface decontamination is achieved, high survival rate and good clinical and radiographic results can be obtained after 3 years. However, only the histological examination could confirm the growth of new bone in direct contact with the implant surface or if the grafted material only fills the space left by the peri-implant defect.
Introduction: Periodontal disease affects more than half of the population in Colombia and is estimated to be one of the leading causes of oral morbidity. Diagnostic aids that allow the evaluation of its extension and severity are of importance since this will provide reliable tools to quantify the severity of the problem. Objective: To determine the inter-examiner agreement for the detection of radiographic findings in patients with localized chronic periodontitis using conventional periapical radiography. Methods: Study of diagnostic tests including patients with localized chronic periodontitis, the tooth with the worst clinical insertion level and a single conventional radiograph per dental organ using parallelism technique. The radiographic evaluations were performed by two independent and blinded evaluators for the findings: lamina dura, bone defects and type of defect. The agreement obtained was estimated through Cohen’s Kappa. Results: A total of 125 radiographs were taken. The mean age was 38.8 ± 9.9, and 61.6% were women. Concordance for lamina dura was 0.08 (95% CI: -0.04–0.21), bone defects 1.00 (95% CI: 1.00–1.00); type of defect present 0.31 (95% CI: 0.29–0.38). Conclusions: Concordance was evaluated as null, almost perfect and acceptable for the findings lamina dura, presence of bone defects and type of defect respectively. For some findings and given the importance of the diagnostic and therapeutic processes, more accurate evaluations are needed which would result in a higher degree of agreement.
RESUMENIntroducción: la enfermedad periodontal afecta más de la mitad de la población en Colombia siendo estimada una de las primeras causas de morbilidad oral. Las ayudas diagnósticas que permitan la evaluación de su extensión y severidad resultan de importancia puesto que así se tendrán herramientas confiables para cuantificar la gravedad del problema. Objetivo: determinar la concordancia interexaminador para la detección de hallazgos radiográficos en pacientes con periodontitis crónica localizada empleando radiografía periapical convencional. Métodos: estudio de pruebas diagnósticas incluyendo pacientes con periodontitis crónica localizada, sobre el diente con peor nivel de inserción clínico y a través de una sola radiografía convencional por órgano dentario empleando técnica de paralelismo. Las valoraciones radiográficas fueron realizadas por dos evaluadores independientes y cegados para los hallazgos: lámina dura, defectos óseos y tipo de defecto. El acuerdo obtenido se estimó a través de Kappa de Cohen. Resultados: se tomaron en total 125 radiografías. La edad promedio fue 38,8±9,9 años, y 61,6% eran mujeres. La concordancia para lámina dura fue 0,08 (IC 95 %: -0,04 -0,21), defectos óseos 1,00 (IC 95 %: 1,00 -1,00); tipo de defecto presente 0,31 (IC 95 %: 0,29 -0,38). Conclusiones: la concordancia se evaluó como nula, casi perfecta y aceptable para los hallazgos lámina dura, presencia de defectos óseos y tipo de defecto respectivamente. Para algunos hallazgos y dada la importancia de los procesos diagnósticos y terapéuticos se necesitan valoraciones más exactas que se traduzcan en un mayor grado de acuerdo.Palabras clave: Reproducibilidad de resultados, diagnóstico, periodoncia, radiografía dental. ABSTRACTIntroduction: periodontal disease affects more than 50% of the Colombian population being considered as one of the main causes of oral morbidity. Diagnostic tests that could evaluate its extension and severity are important since we can account then for reliable tools to quantify the disease severity. Objetive: To estimate the interrater reliability for the detection of radiographic findings in chronic periodontitis patients using conventional periapical radiography. Methods: It was performed a diagnostic test study including patients diagnosed with untreated localized chronic periodontitis including the worst prognosis tooth and performing a single conventional radiography using parallelism technique. We assigned a code for each radiograph and two independent and blinded assessors performed radiographic measurements for the following findings: lamina dura, presence of bone defects and defect type. Agreement evaluation was performed through Cohen's Kappa statistic. Results: We evaluated 125 radiographs. Average age was 38,8±9,9 years from whose 61,6 % were female patients. Reproducibility for lamina dura was 0,08 (95% CI: -0,04 -0,21); bone defects 1,00 (95% CI: 1,00 -1,00) and type of bone defects 0,31 (95% CI: 0,29 -0,38). Conclusions: reliability for lamina dura assessment was considered null, for bo...
