ABSTRACT
BACKGROUND: Oral lichen planus (OLP) is an inmuno-mediated mucocutaneous chronical inflammatory disease. Multiple predisposing factors are considered, such as autoimmune response, microorganisms, medications, dental materials, psychological stress, genetic predisposition or nutritional deficiencies. The deficiency of vitamin D has been related to various autoimmune diseases like OLP. MATERIAL AND METHODS: The electronic search was conducted in the MEDLINE (Pubmed), Scopus, Cochrane Library and Web of Science databases. To assess any potential risk of bias, the authors critically appraised each study by the Newcastle-Ottawa Scale for cohort and case-control studies. Pooled analyses were performed using a random-effects model. Heterogeneity of the studies was assessed by the I2 statistics. Forest Plots were performed to graphically represent the difference between vitamin D concentrations in the OLP compared to healthy group, with a 95% confidence interval. RESULTS: After applying our inclusion and exclusion criteria, 7 articles were included in our review. The median concentration vitamin D in ng/ml found in serum for patients with OLP was of 26,6311,75ng/ml and for healthy patients was of 31,438,7ng/ml. Regarding the quantitative analysis, 7 studies were included. The difference in the concentration of vitamin D in healthy patients and patients with OLP statistically significant (Weighted Mean Difference (WMD): -6.20, 95% CI: -11.24 to -1.15, p=0.02 and I2 heterogeneity: 94%, p<0.00001). CONCLUSIONS: The patients with OLP have statistically lower vitamin D levels than healthy patients.
ABSTRACT
BACKGROUND: Traditional protocols for implant surgery suggest a healing period of 2-3 months from dental extraction to implant placement. Based on all the volumetric modifications produced by that approach, there are authors who advocate for immediate implantology. The aim of the present study was to determine the prevalence of different sockets, and the dimensions of the bone around the upper anterior incisors and canines, to determine the predictability of immediate implants in our population. MATERIAL AND METHODS: This is an observational, cross-sectional study based on cone-beam computed tomography images of the anterior maxila of patients attending the Odontological Hospital of the University of Barcelona (OHUB) and requesting for implant treatment. Different measurements were performed on every analyzed tooth, and also they were categorized by using the main dental sockets classifications. RESULTS: Bone attachment levels and cortical thickness are lower in women compared to men in all three types of teeth (the difference in the bone attachment levels ranges from 4.68%-8.63% and in the bone thickness goes from 0.02-0.58mm). Bone attachment level gradually reduces with age. The reductions observed in all the measurements are higher in the case of canines, compared with the other teeth. The differences from patients <45 years old and patients between 55-64 years old are 13.58±14.55mm in the case of central incisors, 10.04±5.52 in the case of lateral incisors and 22.39±13.65mm in the case of canines. CONCLUSIONS: According to our results, the canines are the teeth with the greatest complexity when it comes to immediate implantology treatments. Furthermore, that kind of treatment is more complex as age increases, since we observed a gradual percentage of unfavourable sockets in older patients.

BACKGROUND: Oral squamous cell carcinoma (OSCC) is gradually increasing its incidence in our society. Unfortunately, this entity is diagnosed at an advanced stage in most patients, a fact that implies greater difficulty in its treatment and a worse prognosis. This systematic review aims to assess whether the cytokines IL-6, IL-8 and TNF-α are potential salivary biomarkers that allow early diagnosis of cancer. MATERIAL AND METHODS: An electronic search was performed in three databases (Pubmed, Scopus and Web of Science). We used the following keywords: "salivary cytokines", "saliva cytokines", "salivary interleukins", "biomarkers", "oral squamous cell carcinoma" and "diagnosis", combined with the Boolean operators "AND" and "OR". RESULTS: 128 publications were found and finally 23 articles were included in the review and 15 in the meta-analysis. It has been observed that the majority of OSCC patients express higher salivary concentrations of IL-6, IL-8 and TNF-α compared to the control (CL) and premalignant lesion (OPML) groups. It has also been observed that the different premalignant lesions do not have statistically significant differences in the salivary concentration of the cytokines, and on the other hand, differences have been observed between the different TNM stages. The meta-analysis has shown that the difference in concentration of IL-6, IL-8 and TNF-α is statistically significant between the CL group and the OSCC, and also between the CL group and OPML. CONCLUSIONS: There is sufficient evidence to affirm that IL-6, IL-8 and TNF-α are useful salivary cytokines in the early diagnosis and prognosis of OSCC. Although future studies are necessary to establish greater reliability of these biomarkers and thus be able to develop a valid diagnostic test.

Introducción: La correcta homeostasis oral, asociada a una buena higiene oral, es necesaria para disminuir la de patógenos cariogénicos y la inhibición de patógenos periodontales, así como modular la respuesta inflamatoria. El objetivo de este estudio es evaluar los efectos de un dentífrico para la protección del microbioma oral, en pacientes atendidos en el Hospital Odontológico Universidad de Barcelona (HOUB). Material y métodos: Ensayo Clínico Randomizado doble ciego y placebo en pacientes atendidos en el HOUB. En el Grupo estudio [GE] se utiliza una pasta dentífrica específica [PDE], que contiene como ingredientes activos aceite de oliva virgen extra, betaina y xilitol además de monofluorofosfato de sodio (1,450 ppm F-) + Excipientes. Y en el Grupo control [GC] se utiliza una pasta placebo sin ingredientes activos. A todos los pacientes se les realiza una exploración oral con parámetros clínicos periodontales, medición de pH, flujo salival (no estimulado y estimulado), recuento de citoquinas (TNF, IL-1 e IL-4.) y de carga total bacteriana, mediante PCR cuantitativa, al inicio y al mes del tratamiento. Resultados: Se incluyen un total de 26 pacientes, 17 mujeres y 9 hombres con una edad media de 48,76 años. El nivel de pH se mantuvo estable entre el inicio y final del estudio en ambos grupos, sin diferencias entre ellos. 11 pacientes indicaron la sensación subjetiva de encontrar la boca mejor, 7 eran test y 4 control (p=0.1); 10 pacientes encontraron la boca igual y solo uno (placebo) la encontró peor. En el análisis de la carga bacteriana mediante determinación de PCR cuantitativa de gen16S solo se analizaron 10 pacientes: 5 GE y 5 GC. En el grupo test bajó en todos los casos la carga de patógenos periodontales y en el grupo control, disminuyó en 4 aumentando en 1. En los 16 pacientes que se analizaron las citoquinas no se observaron diferencias estadísticamente significativas. (AU)
Introduction: Correct oral homeostasis, associated with good oral hygiene, is necessary to decrease the bacterial load of cariogenic pathogens and the inhibition of periodontal pathogens, as well as to modulate inflammatory response. The objective of this study is to evaluate the effects of a toothpaste for the protection of the oral microbiome, in patients treated at the Hospital Odontológico Universidad de Barcelona (HOUB).Material and methods: Randomized double-blind clinical trial with placebo in patients treated at HOUB. In the Study Group [SG] a specific toothpaste [PDE] is used, which contains as active ingredients extra virgin olive oil, betaine and xylitol, as well as sodium monofluorophosphate (1,450 ppm F-) + Excipients. In the control group [CG] a placebo paste without active ingredients is used. All patients underwent an oral examination with periodontal clinical parameters, pH measurement, salivary flow (stimulated and unstimulated), cytokine count (TNF, IL-1 and IL-4.) and total bacterial load by qPCR16S at the beginning and one month after treatment.Results: A total of 26 patients were included, 17 women and 9 men, with a mean age of 48.76 years. The pH level remained stable between the beginning and the end of the study in both groups, with no differences between them. 11 patients felt their mouth was in a better state, 7 of which were test and 4 control (p=0.1); 10 patients felt their mouth was in the same as before the treatment; and only one (placebo) felt it was worse. For the 16S analysis, only 10 patients were analyzed: 5 SG and 5 CG. In the test group, the total bacterial load decreased in all cases, and in the control group, it decreased in 4 and increased in 1. Among the 16 patients whose cytokines were analyzed, no statistically significant differences were observed. (AU)

BACKGROUND: Burning mouth syndrome is an idiopathic condition characterized by burning pain in a normal-appearing oral mucosa lasting at least four to six months. In the case of secondary burning mouth syndrome is associated with local or systemic factors (such as thyroid disorders) that can cause these symptoms. The aim of this review was to study the relationship between thyroid disorders and burning mouth syndrome. MATERIAL AND METHODS: The present study followed the PRISMA guidelines. An electronic search strategy was developed for PubMed/Medline, Scopus and Cochrane. The following combination of keywords and Boolean operators were used: Thyroid AND burning mouth; Thyroid AND burning mouth syndrome; Hypothyroidism AND burning mouth; Hypothyroidism AND burning mouth syndrome; Hyperthyroidism AND burning mouth; Hyperthyroidism AND burning mouth syndrome. The results were processed by existing free software in https://www.graphpad.com/. To evaluate the association of the categorical variables we used the Fisher test at a level of significance of p-value ≤ 0,05. As a primary summary measure the Odds Ratio (OR) has been used. To analyze the risk of bias the guidelines of the GRADE guide were used and the grade of evidence was analyzed by the guide of Joanna Briggs Institute: Levels of Evidence and Grades of Recommendations. RESULTS: After applying the inclusion and exclusion criteria, 5 studies were selected for review. The Chi-square was 10.92 and the Odds Ratio was 3.31 with respect to TSH values with p <0.0001 (Fisher's test). The population of patients with TSH alterations is increased in 80.49% and decreased in 19.51%. CONCLUSIONS: It can be concluded that thyroid hormone abnormalities are a factor in secondary burning mouth syndrome; specially in patients with hypothyroidism.

BACKGROUND: Recurrent Aphtous Stomatitis (RAS) is the most common process affecting the oral mucosa. It is painful, multifactorial and generally recurrent. The aim of this systematic review is to know the last treatment approaches and their effectivity. MATERIAL AND METHODS: we compared the outcome of different kind of treatments in terms of the improvement of the lesions, reduction of the size of those lesions and the time needed for their healing. Inclusion criteria were: clinical trials, articles written in English or Spanish and published less than 5 years ago. RESULTS: we used the following keywords: "treatment", "aphtous stomatitis", "canker sores"; combined with Boolean operators AND y OR. We selected 28 articles for reading the whole text, and after applying the eligibility criteria, we selected 17 articles for our revision. Among all the treatments, we emphasize the barrier method based in compound of cellulose rubber and a calcium/sodium copolymer PVM/MA, with which the difference in the 3rd and 7th day was of -6,29 ± 0,14 points in the pain score. The treatment with insulin and chitosan gel, brought a pain suppression on the third day, with no reactivation of the pain during the whole study. The application of a film composed of polyurethane and sesame oil with chitosan, brought a reduction in the size of the lesions of 4,54 ± 2,84mm on the 6th day compared with the situation before the beginning of the treatment. The different kinds of laser, which produced a reduction in the pain score just at the beginning of the treatment up to 8,1 ± 1,6 points, and a reduction of the size of the lesions of 4,42 ± 1,02mm on the 7th day. CONCLUSIONS: Besides the classic treatments for RAS, we have to take into account other treatment modalities, above all the different kinds of laser.

Introducción: Las enfermedades periodontales necrotizantes son cuadros agudos que se acompañan de signos y síntomas locales y sistémicos que se caracterizan por la necrosis de tejidos gingivales, periodontal, pudiendo incluir otros tejidos orales dependiendo de la severidad de la infección. En esta revisión sistemática queremos evaluar cuáles son los factores predisponentes de mayor relevancia para el desarrollo de estas infecciones, así como las medidas terapéuticas más efectivas para tratarlas. Material y métodos: Realizamos una búsqueda bibliográfica en tres bases de datos (PubMed, Cochrane y Scopus) de los últimos 10 años. Se usaron las siguientes palabras clave: necrotisingulcerative gingivitis, necrotising ulcerative periodontitis, necrotising ulcerative stomatitis y aetiology; combinados con los operadores boleanosAND y OR. Resultados: Después de aplicar los criterios de exclusión, quedan 19 artículos. Entre los factores de riesgo más importantes encontramos la malnutrición severa, la mala higiene oral y los depósitos de placa dental, las infecciones previas y los cuadros de inmunosupresión. En cuanto a las intervenciones terapéuticas, la literatura destaca el desbridamiento supra y subgingival. La terapia farmacológica más utilizada es el metronidazol como monoterapia o combinado con amoxicilina. Los coadyuvantes más empleados fueron los colutorios de clorhexidina y el peróxido de hidrógeno. Conclusiones: Las enfermedades periodontales necrotizantes son entidades de etiología mayormente bacteriana inespecífica que están sujetas a factores causales que afectan al estado general del paciente. El tratamiento de las mismas se basa en el control de los factores de riesgo a la vez que se soluciona la infección. (AU)
Introduccion: Periodontal necrotising diseases are acute conditions accompanied by local and systemic signs and symptoms characterised by gingival tissues necrosis; however, they can include periodontal or other oral tissues depending on the severity of the infection. In this systematic review we want to evaluate which are the most relevant predisposing factors for the development of these infections, as well as the therapeutic approaches that have shown affectivity against them. Material and methods: A bibliographic search of the last 10 years was conducted in three databases (PubMed, Cochrane y Scopus). We used the following keywords: necrotising ulcerative gingivitis, necrotising ulcerative periodontitis , necrotising ulcerative stomatitis y aetiology; combining them with Boolean operators (AND and OR). Results: After applying the exclusion criteria, 19 papers remained. Among the most important risk factors we found severe malnutrition, the bad oral hygiene and deposits of tartar, previous infections and immunosuppression. Regarding to therapeutic interventions, literature highlights supragingival and subgingival debridement. The most used pharmacological strategy is monotherapy with metronidazole or combined with amoxicillin. The most used adjuvant treatments are chlorhexidine and peroxide mouthwashes. Conclusions: Periodontal Necrotising diseases are entities which have a mainly unspecific bacterial cause and depend on causative factors that affect to patient's general state. Their treatment is based on the control of risk factors while we solve the infection. (AU)

INTRODUCTION: Inflammatory papillary hyperplasia (IPH) is a benign lesion of the palatal mucosa. It is usually found in denture-wearers but also has been reported in patients without a history of use of a maxillary prosthesis use. OBJECTIVES: The aim of this study is to review the literature to assess the prevalence of denture stomatitis and inflammatory papillary hyperplasia and the etiological factors associated. MATERIAL AND METHODS: A search was carried out in PubMed (January 2005 to October 2015) with the key words "inflammatory papillary hyperplasia", "denture stomatitis", "granular stomatitis" and "Newton's type III" The inclusion criteria were studies including at least a sample of 50 apparently healthy patients, articles published from 2005 to 2015 written in English. The exclusion criteria were reviews and non-human studies. RESULTS: Out of the 190 studies obtained initially from the search 16 articles were selected to be included in our systematic review. The prevalence of denture stomatitis was 29.56% and 4.44% for IPH. We found 5 cases of denture stomatitis among non-denture-wearer individuals. All IPH cases were associated with the use of prosthesis. Smoking and continued use of ill-fitting dentures turned out to be the most frequent risk factors for developing IPH. CONCLUSIONS: IPH is a rare oral lesion and its pathogenesis still remains unclear. Its presentation among non-denture-wearers is extremely unusual.

El objetivo de este trabajo es realizar una revisión bibliográfica de los últimos 5 años (2006-2011), sobre la situación actual de los caninos incluidos y su tratamiento. Se ha analizado la incidencia, etiología, diagnóstico y factores pronósticos de su alineamiento, así como las terapéuticas de los mismos. Su manejo es de especial importancia, ya que estos dientes tienen un papel fundamental en la apariencia facial, estética dental, desarrollo del arco dental y la oclusión funcional. Se deben diagnosticar mediante una evaluación clínica y radiológica minuciosa además de un examen radiográfico; determinando las posibles complicaciones asociadas y las opciones de tratamiento individualizándolas en cada caso. Se han planteado diferentes formas de manejarlos que van desde los controles periódicos, la prevención de la inclusión con el tratamiento interceptivo, el tratamiento ortodóncico-quirúrgico o la extracción. Antes de iniciar cualquier procedimiento debemos valorar las características individuales de cada paciente, así como la situación y la inclinación del diente para lograr nuestro objetivo (AU)
The aim of this article is to make a bibliographical review, from studies performed in the last 5 years (2006-2011), to analyse the current trends of the unerupted canines in its epidemiology, aetiology, diagnostic methods, prognostic factors in their alignment; and the various treatment options available. It is especially important because of its relevance in the facial appearance, dental aesthetics and functional occlusion. The diagnosis of the unerupted canine should be made through a thorough clinical and radiographic examination, because it helps in determining the best treatment plan and prevention and/or evaluation of possible complications. Different ways to manage such cases have been suggested from periodic controls, preventing the impaction using interceptive treatment, surgical and orthodontic techniques, and lastly, extraction. Thus, before commencing with any treatment, a proper evaluation of the patient characteristics and the characteristics of the canine should be evaluated to achieve the best possible outcome (AU)
