Exploring the prevalence and risk factors of benign and premalignant oral lesions in an adult population from Northern Spain: a pilot study.

OBJECTIVE: The goal was to identify the lifestyle risk factors associated with benign and potentially malignant oral disorders. METHOD AND MATERIALS: The study enrolled first-time patients from the Oral Pathology Section, volunteers from Oviedo, and first-time patients from University of Oviedo dental clinic. Patients underwent a survey that included sociodemographic information, lifestyle habits, and medical history. Then, a comprehensive examination of the oral mucosa was conducted. Univariate and multivariate logistic regression were conducted using R software. RESULTS: Among the 183 participants, the most prevalent lesions were varicose veins (43.2%), cheek/lip biting (34.97%) and coated tongue (33.3%). Among the OPMDs (16.4%), oral lichen planus (OLP, 12.64%) and leukoplakia (3.3%). Tobacco was associated with melanotic pigmentation (OR 3.87, p= 0.001) and coated tongue (OR 5.90, p= 0.001). Longer intervals since last check-up were associated with traumatic keratosis (OR 2.05, p=035). Age and heavy smoking were found to have higher risk of developing an OPMD (OR 1.04, p=0.035 and OR 7.35, p=0.028 respectively). CONCLUSIONS: Our data should be considered when organizing public health programs focused on the detection and screening of heavy smokers. It is also important to strengthen the oral pathology units in universities as reference centres for students to acquire the necessary knowledge for their diagnosis and treatment, while simultaneously promoting awareness of this risk factor for oral precancer among the general population.

Association of oral lichen planus and psoriasis: a case-control study.

OBJECTIVE: The aim of the present study was to investigate whether psoriasis disease constitutes a risk factor for OLP, by assessing the prevalance of psoriasis in a test group with OLP and the control group without. METHOD AND MATERIALS: A cohort of consecutive patients diagnosed clinically and histologically with OLP between 2014 and 2022 was analyzed. The results were contrasted with those obtained in control series matched for age and sex. The correlations between OLP and sex, age, tobacco, alcohol consumption, and psoriasis were assessed using Pearson chi-square test. Multivariate regression analysis was performed to evaluate the association between psoriasis and OLP. For the assessment of the quality of the statistical models, the Akaike information criterion was used. RESULTS: The study involved 1,016 patients; 738 women (72.6%) and 278 men (27.4%). The average age was 59.38 ± 12.55 years. Of 508 patients with OLP, 16 (3.15%) had comorbid psoriasis, and this was 5 (0.98%) in the control group. Age, sex, smoking, and alcohol habits were not predictive variables in the relationship between psoriasis and OLP in these patients. There were statistically significant differences in relation to the number of locations, with greater extension in patients with OLP and psoriasis (P = .002). According to the multivariate analysis, the odds ratio of OLP for psoriasis was 3.13 (95% CI 1.20-9.68). CONCLUSIONS: This is the first study showing the potential association between psoriasis and OLP, and the results should be considered to improve knowledge of comorbidity of OLP. Based on the results, it is recommended that clinicians collect data regarding history of psoriasis in patients with OLP, and consider possible multiple intraoral locations.

Public Awareness on Oral Cancer: A Population- Based Study in Asturias.

OBJECTIVE: Through awareness campaigns, we can change the patient's abilities to detect oral cancer at an early stage and their ability to seek help. To focus these campaigns, we need to know the level of knowledge of the population and its interest in learning about this disease. The aim of this study was to assess the level of oral cancer awareness in Asturias and the interest of the population in learning about this pathology. METHODS: A representative community-based survey was carried out online using Google Forms®. Responses were transferred to a Microsoft Excel and analysed using the R-program. The relationship between two qualitative variables was studied using Pearson's Chi-square test or Fisher's test. Univariate and multivariate logistic regression models were used to determine which factors are associated with knowledge of oral cancer. RESULT: We found that those having over 50 years and being health professionals are more likely to know about the existence of oral cancer. Almost 85.1% of participants mentioned tobacco as a risk factor, only 39.8% identified alcohol. The ulcer was the most frequently recognized alarm sign (70.6%). The primary care physician was chosen as the first option for consultation by the 56.5% of the sample. Only 12.4% of the participants reported knowing how to self-examine their mouth. The number of views of a video of how-to self-inspection oral cavity displayed at the end of the questionnaire increased in a 39.38% during our study period. CONCLUSION: This survey showed a worrying lack of awareness and knowledge about oral cancer among the population of Asturias, especially among those under 50 years old. The interest shown in increasing their knowledge, give us hope in the success of future awareness campaigns.

Bidirectional Association between Lichen Planus and Hepatitis C-An Update Systematic Review and Meta-Analysis.

Lichen planus (LP) is a chronic, inflammatory mucocutaneous disorder associated with systemic diseases such as hepatitis C (HCV). The objective of this study is to evaluate the association between LP and HCV bidirectionally through a systematic review and meta-analysis. A comprehensive search of studies published was performed in the databases of PubMed, Embase, and Web of Science. Out of 18,491 articles, 192 studies were included. The global prevalence of HCV positive (HCV+) in LP patients registered from 143 studies was 9.42% [95% confidence interval (CI), 7.27-11.58%], and from these, 84 studies showed HCV+ 4-fold more frequent in LP than a control group (OR, 4.48; 95% CI, 3.48-5.77). The global prevalence of LP in patients HCV+ recorded from 49 studies was 7.05% (95% CI, 4.85-9.26%), and from these, 15 registered a 3-fold more LP in HCV (OR, 3.65; 95% CI, 2.14-6.24). HCV+ in LP patients showed great geographic variability (OR, 2.7 to 8.57), and the predominantly cutaneous location was higher (OR, 5.95) than the oral location (OR, 3.49). LP in HCV+ patients was more frequent in the Eastern Mediterranean (OR, 5.51; 95% CI, 1.40-15.57). There is a higher prevalence of HCV+ in LP and vice versa than in the control group, especially in certain geographical areas that should be taken into consideration when doing screening in countries with an upper prevalence of HCV among the general population.

[Prevalence of dental and mucosal lesions among the pediatric population who attended the emergency department of a general hospital].

BACKGROUND: The high prevalence of oral pathology in children encourages to gain further understanding on their manifestations and urgent nature, objective of the present study Methodology. Cross-sectional study that included patients aged <14 years of age who attended an emergency department over a one-year period. The relationship between the variables collected and oral pathology was analyzed. RESULTS: Fifty-five patients were included, 45.5% girls, mean age 4.11 years (10 days to 13 years). Overall, mucosal pathology (74.5%) prevailed over dental ones, and lesions of infectious origin (54.6%) over the traumatic ones (14.5%). Dental pathology (50% toothache and 35.7% infections) was significantly associated with being >6 years (66.7 vs 10%), pain (40.7 vs 10.7%) and absence of fever (37.9 vs 11.5%). Mucosal pathology (61% infections: 53.7% viral and 31.7% due to herpangina) was significantly associated with being =6 years (60 vs 6.7%) and having fever (76.9 vs 17.2%). Six traumatic lesions on the mucosa and two on the teeth were observed; significantly more patients attended the emergency room within 24 hours (median =1 hour) than in the case of infection (100 vs 51.7%). Being =6 years was significantly associated with fever, mucosal pathology, mucosal infection, and herpangina, and being >6 years was associated with pain, previous antibiotic treatment and at discharge, and previous NSAID regimen. CONCLUSIONS: The analyzed pediatric oral pathologies treated in the emergency department are of mucosal and infectious origin. Dental disease prevail in children >6 years of age and mucosal lesions in those =6 years; no sex differences are observed.

Fundamento: La elevada prevalencia de la patología oral infantil incentiva a conocer sus manifestaciones y el carácter urgente de las mismas, objetivo del presente estudio. Metodología: Estudio transversal que incluyó pacientes de edad <14 años que acudieron a un servicio de urgencias durante un año. Se analizó la relación entre las variables recogidas y la patología oral. Resultados: Se incluyeron 55 pacientes, 45,5% niñas, edad media 4,11 años (10 días a 13 años). Globalmente, predominó la patología mucosa (74,5%) frente a la dentaria, y el origen infeccioso (54,6%) frente al traumático (14,5%). La patología dentaria (50% odontalgia y 35,7% infecciones) se asoció significativamente a edad >6 años (66,7 vs 10%), dolor (40,7 vs 10,7%) y ausencia de fiebre (37,9 vs 11,5%). La patología mucosa (61% infecciones: 53,7% víricas y 31,7% por herpangina) se asoció significativamente a edad ≤6 años (60 vs 6,7%;) y fiebre (76,9 vs 17,2%). Se observaron seis lesiones traumáticas sobre la mucosa y dos en los dientes; significativamente más pacientes acudieron a urgencias antes de 24 horas (mediana =1 hora) que en caso de infección (100 vs 51,7%). La edad ≤6 años se asoció significativamente a fiebre, patología mucosa, infección de la mucosa y herpangina, y la >6 años se asoció a dolor, tratamiento antibiótico previo y al alta y pauta previa de AINE. Conclusión: La patología oral infantil atendida en el servicio de urgencias analizado fue de la mucosa y origen infeccioso, predominando la dentaria en >6 años y la mucosa en ≤6 años, sin diferencia por sexo.(AU)

Risk of Prediabetes and Diabetes in Oral Lichen Planus: A Case-Control Study according to Current Diagnostic Criteria.

OBJECTIVE: To estimate the prevalence of prediabetes and diabetes in patients with oral lichen planus (OLP). METHODS: Prospective cohort, including consecutive patients diagnosed clinically and histologically with OLP from 2018 to 2022. Patients and controls were matched by age and gender. Fasting plasma glucose value collection from all patients. Multivariate regression analysis evaluated the relationship between prediabetes and diabetes variables according to current diagnostic criteria. RESULTS: The sample comprised 275 patients (207 women; 75.3%), mean age 59.60 ± 12.18 years for both groups. Prediabetes was diagnosed according to the American Diabetes Association (ADA, 100-125 mg/dL), in 21.45% of OLP patients (59/275) and 14.55% (40/275) of control patients (p = 0.035). Patients with the atrophic-erosive form exhibited stronger association with taking oral antidiabetics (p = 0.011). Multivariate analysis showed that being over >60 years and having a cutaneous location was associated with ≥3 sites (OR 1.81 and OR 2.43). ADA prediabetes and oral antidiabetics drugs increased the probability of OLP (OR 1.60 (1.04-2.51), p = 0.03 and OR 2.20 (1.18-4.69), p = 0.017) after adjustment for sex and age. CONCLUSIONS: Because glycemia 100-125 mg/dL was associated with OLP, testing serum fasting plasma glucose seems reasonable in order to prevent development of diabetes and deal with possible complications until new studies are complete.

Analysis of the esthetic preferences of Spanish laypersons and dentists regarding the different width proportions of the maxillary anterior teeth.

STATEMENT OF PROBLEM: Multiple esthetic width proportions have been described for maxillary anterior teeth. However, the esthetic characteristics of each have not been compared simultaneously to determine which proportion is preferred by dentists and laypersons. PURPOSE: The purpose of this study was to evaluate the preferences of dentists and laypersons with respect to internationally recognized dental esthetic proportions. It also sought to determine whether a relationship existed among dentists' preferences as per their specialty and among laypersons as per their academic field. MATERIAL AND METHODS: Two smile images, one male and one female, were digitally modified to meet the golden proportion and the recurring esthetic dental (70%) and golden percentage. The 2 resulting sets of images (original images and digitally altered ones) were presented to dentists and laypersons through a Web-based survey site. The Pearson chi-squared and Fisher tests were used to assess the differences in the esthetic preferences among the groups (α=.05). RESULTS: A total of 363 answers were obtained from dentists and 750 from laypersons. Both groups considered recurring esthetic dental to be the most esthetic proportion and golden proportion to be the least esthetic proportion. The dentists' preferences as per their specialty followed the same trend, whereas the laypersons' preferences were more scattered according to their academic field. The recurring esthetic dental proportion was preferred in images of both sexes, golden proportion smiles were the least preferred for female smiles, and golden percentage was the least preferred for male smiles. CONCLUSIONS: The results obtained indicated that the preferred esthetic proportion both for dentists and laypersons was the recurring esthetic dental 70%, with the dentists' specialty or laypersons branch of knowledge not affecting choice.

Risk factors associated with tongue lesions: a propensity score-matched case-control study

Background: to analyse the potential risk factors of tongue lesions, comparing the results with a control group. Material and Methods: An observational, case-control study was designed. The study included a case group comprising 336 patients with tongue lesions and 336 sex and age-matched controls. We recorded tobacco/alcohol habits, presence of dentures, allergies, medical conditions, and medications. Statistical analysis was performed via logistic regression models to estimate the odds ratio (OR) adjusted for gender, age, tobacco, and alcohol using propensity score-matching analysis (PSM). Results: According to the final PSM model, patients with tongue lesions were more likely to suffer from allergies (OR 2.13; 1.27-3.66) or medical conditions (OR 2.14; 1.19-3.85), and more likely to take medication (OR 1.99; 1.11-3.57). Elderly individuals were more prone to hairy tongue (OR 3.82; 1.53-10.47). Smoking was associated with coated tongue (OR 2.05; 1.12-3.63), hairy tongue (OR 3.77; 1.52-9.22) and median rhomboid glossitis (OR 40.49; 5.84-860.43). Allergic individuals were more likely to exhibit sublingual varices (OR 1.73; 1.02-2.88). Medical conditions increased the chances of having coated tongue (OR 2.44; 1.36-4.64) or crenated tongue (OR 2.70; 1.42-5.30). Arterial hypertension was associated with median rhomboid glossitis (OR 5.85; 1.08-34.18). Individuals on medication showed a higher risk of fissured tongue (OR 1.87; 1.20-2.94) and varices (OR 2.42; 1.58-3.80). Agents acting on the alimentary tract and metabolism increased the probability of fissured tongue (OR 2.31; 1.42-3.79). Conclusions: As far as we are aware, this is the first study on lingual pathology to include a PSM analysis. The results suggest that a history of allergies, the presence of medical conditions, and the use of medication are associated with increased probability of tongue lesions. The analysis of diseases and medications by subgroups requires studies matched by habits with larger sample sizes, in order to corroborate our observations.(AU)

Role of Artificial Intelligence in the Early Diagnosis of Oral Cancer. A Scoping Review.

The early diagnosis of cancer can facilitate subsequent clinical patient management. Artificial intelligence (AI) has been found to be promising for improving the diagnostic process. The aim of the present study is to increase the evidence on the application of AI to the early diagnosis of oral cancer through a scoping review. A search was performed in the PubMed, Web of Science, Embase and Google Scholar databases during the period from January 2000 to December 2020, referring to the early non-invasive diagnosis of oral cancer based on AI applied to screening. Only accessible full-text articles were considered. Thirty-six studies were included on the early detection of oral cancer based on images (photographs (optical imaging and enhancement technology) and cytology) with the application of AI models. These studies were characterized by their heterogeneous nature. Each publication involved a different algorithm with potential training data bias and few comparative data for AI interpretation. Artificial intelligence may play an important role in precisely predicting the development of oral cancer, though several methodological issues need to be addressed in parallel to the advances in AI techniques, in order to allow large-scale transfer of the latter to population-based detection protocols.

Analysis of dental esthetic proportions in a Spanish population sample.

PURPOSE: The present study aimed to analyze in a Spanish population sample the compliance of the anterior maxillary teeth to the dental esthetic proportions described in the literature. METHODS: Photographs of the smiles of 78 individuals were calibrated and digitally analyzed considering the following proportions: golden proportion (GP), recurring esthetic dental (RED), golden percentage (GPG), Preston's proportion and Modified golden percentage (MGPG). For statistical analysis, the t-test of an independent sample was applied, and compliance percentages for each standard were recorded. RESULTS: The existence of RED 70% or 80% has not been registered. The percentages of compliance with GP were within a range between 0% and 16%. The mean tooth width ratios were adjusted to the values described by Preston (P > 0.05), but the compliance percentages were low (3.33-25%). GPG only presented high percentages of compliance in the lateral incisors (53.33-62.5%). MGPG showed the highest percentages of compliance (50-68%). CONCLUSION: After analyzing a Spanish population sample using smile photographs for the first time, GP, RED, GPG and Preston's proportion standards are not fulfilled and therefore, not suitable for treatments that seek a smile that reproduces natural principles. However, the values designated by MGPG with a deviation of ±1% are largely applicable for treatments that aim for a natural smile.

Two-Dimensional Analysis of Digital Images through Vector Graphic Editors in Dentistry: New Calibration and Analysis Protocol Based on a Scoping Review.

This review was carried out to analyse the functions of three Vector Graphic Editor applications (VGEs) applicable to clinical or research practice, and through this we propose a two-dimensional image analysis protocol in a VGE. We adapted the review method from the PRISMA-ScR protocol. Pubmed, Embase, Web of Science, and Scopus were searched until June 2020 with the following keywords: Vector Graphics Editor, Vector Graphics Editor Dentistry, Adobe Illustrator, Adobe Illustrator Dentistry, Coreldraw, Coreldraw Dentistry, Inkscape, Inkscape Dentistry. The publications found described the functions of the following VGEs: Adobe Illustrator, CorelDRAW, and Inkscape. The possibility of replicating the procedures to perform the VGE functions was analysed using each study's data. The search yielded 1032 publications. After the selection, 21 articles met the eligibility criteria. They described eight VGE functions: line tracing, landmarks tracing, linear measurement recording, angular measurement recording, image calibration, image overlay, file transfer, and vector graphics development. The features offered by the VGEs bring great precision and objectivity to two-dimensional image analysis. The image analysis and editing procedures are currently not protocolised. Thus, a protocol for image calibration and measurement recording is proposed in order to guarantee the protocol's replication.

Effect of a Preventive Oral Health Program Starting during Pregnancy: A Case-Control Study Comparing Immigrant and Native Women and Their Children.

The objective was to evaluate whether including pregnant women in a preventive dental program prevented the appearance of caries in their children up to the age of 6, and whether the effect was similar in children of immigrant and non-immigrant women. In phase I, 90 pregnant women, 45 immigrants and 45 natives, were taught about the development and prevention of caries. In phase II the oral health of their children at the age of 6 (n = 90) was evaluated, along with a control group of children of natives and immigrants of the same age (n = 90). A survey was used to determine participants' backgrounds and habits. A multivariate study of the results was performed using R-core software. The number of children without caries was 128 (71.1%), whereas 52 (28.9%) had caries, 15 from the protocol (16.67%) and 37 from the control group (41.11%), with statistically significant differences (p < 0.001). The mean number of caries for the children in the protocol was 0.62 ± 2 and in the control group it was 1.88 ± 2.9 (p = 0.001). In the multivariate analysis the risk of developing caries was higher for the condition of being the child of an immigrant (OR = 11.137), inadequate oral health (OR = 4.993), the children being overweight at the age of 6 (OR = 10.680), and the consumption of candies (OR = 5.042). In conclusion, the preventive protocols started during pregnancy reduced caries in participants' children, which suggests that these protocols should be encouraged. Because immigrant children are more vulnerable to caries, they and their parents should be included in preventive programs once they arrive in the host country.

Study of factors influencing preoperative detection of alveolar antral artery by CBCT in sinus floor elevation.

This study aimed at assessing the prevalence of alveolar antral artery (AAA) detection by CBCT, its related variables, and at describing explanatory models useful in surgical planning, by retrospective evaluation of CBCT explorations. The modelling of the probability for detecting AAA was undertaken using logistic generalized additive models (GAM). The capacity for discriminating detection/no detection was assessed by receiver operating characteristic curves. A total of 466 sinuses were studied. Univariate models showed detection probability was linked to sinus width and thickness of the lateral bony wall, together with the shape and height of the osseous crest. AAA detection probability increased steadily until the thickness of the bony wall reached 6 mm. Multivariate models resulted good discriminators for AAA detection, particularly for females, showing an area under the curve (AUC) of 0.85. Models considering patients altogether, and those including only males offered slightly lower values (AUC = 0.79). The probability of AAA detection by CBCT was influenced by gender (higher in males and for narrow sinuses) and increases with the thickness of the sinus lateral bony wall and the height of the residual alveolar ridge. Besides, and particularly for women, the thickness of the ridge at the basal level seems to improve the explanatory model for AAA detection.

People would rather see a physician than a dentist when experiencing a long-standing oral ulceration. A population-based study in Spain

BACKGROUND: Primary care physicians have been reported to be the first choice for patients with oral ulcerations. This study investigates the health-seeking behaviour of lay public in Galicia (North-western Spain) if experiencing a long-standing oral ulceration. MATERIAL AND METHODS: Cross-sectional population-based survey of randomly selected respondents conducted from March 1, 2015 to 30 June 2016. RESULTS: A total of 5,727 pedestrians entered the study (response rate: 53%), mostly in the 45-64 age group (30.2%; n = 1,728), 47.7% of them (n = 2,729) were males. Most participants (42.1%; n = 2,411) reported to visit their dentist once a year and had secondary or compulsory education as their highest educational achievement (28.18%, n = 1,614; 28%, n = 1,600 respectively).When questioned what they would do if they had a wound/ulceration lasting longer than 3 weeks, most participants answered they would go to see their primary care physician (62.8%; n = 3,597) and less than one quarter of the sample (23.8%; n = 1,371) would seek consultation with their dentist. CONCLUSIONS: General Galician population would seek professional consultation about a long-standing oral ulceration, relying mostly on primary care physicians. Those neglecting these lesions are elderly, less-schooled people and unaware of oral cancer

Oral mucosal peeling related to dentifrices and mouthwashes: A systematic review

Background: The aim of this systematic review was to summarise the clinical information available about oral mucosal peeling (OMP) and to explore its aetiopathogenic association with dentifrices and mouthwashes. Material and Methods: PICOS outline: Population: subjects diagnosed clinically and/or pathologically. Intervention: exposition to oral hygiene products. Comparisons: patients using products at different concentrations. Out-comes: clinicopathological outcomes (primary) and oral epithelial desquamation (secondary) after use. Study de-sign: any. Exclusion criteria: reports on secondary or unpublished data, in vitro studies. Data were independently extracted by two reviewers. Results: Fifteen reports were selected from 410 identified. Descriptive studies mainly showed low bias risk, ex-perimental studies mostly an "unclear risk". Dentifrices or mouthwashes were linked to OMP, with an unknown origin in 5 subjects. Sodium lauryl-sulphate (SLS) was behind this disorder in 21 subjects, tartar-control dentifrices in 2, and flavouring agents in 1 case. Desquamation extension was linked to SLS concentration. Most cases were painless, leaving normal mucosa after desquamation. Tartar-control dentifrices caused ulcerations more frequently. Conclusions: OMP management should consider differential diagnosis with oral desquamative lesions, particularly desquamative gingivitis, with a guided clinical interview together with pathological confirmation while discouraging the use of the product responsible for OMP

Oral hygiene instructions and professional control as part of the treatment of desquamative gingivitis. Systematic review

Background: The aim of this present article was to evaluate the scientific evidence on the efficacy of daily hygiene and professional prophylaxis for treatment of desquamative gingivitis. Material and Methods: The present systematic review was conducted following the PRISMA protocol. Searches were carried out in Pubmed, Embase, Web of Science and Cochrane Library up to July 2018, randomized clinical trials and cohort studies on desquamative gingivitis (DG), and oral diseases joined to DG. Results: After screening, we found that nine publications met the eligibility criteria eight cohort studies and one randomized control trial. The diagnosis of the diseases corresponded to oral lichen planus (n=185), mucous membrane pemphigoid (n=13); plasma cell gingivitits (n=15) and pemphigus vulgar (n=11). The follow-up was between a week and a year after instructing patients. Dental daily hygiene and professional prophylaxis, at least with supragingival scaling and polishing have significantly improved the extension of the lesion and reduced the activity of DG, and gingival bleeding in all patients. Furthermore, these techniques have also reduced pain and gingival plaque. Conclusions: In conclusion the studies presented support the efficacy of maintaining personal and professional oral hygiene in patients with GD, reducing the clinical signs of the disease, regardless of its pathogenesis

Association between geographic tongue and psoriasis: A systematic review and meta-analyses.

Geographic tongue (GT) has been described as a predictor of psoriasis. The objective of this study was to analyse the prevalence of GT in psoriatic and non-psoriatic patients. For this purpose, we conducted a systematic review and meta-analysis. A literature search was performed on PubMed, Embase, Web of Science and the Cochrane Database of Systematic Reviews. The search and selection process was performed according to the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) criteria. Only case-control studies were selected, and the prevalence of GT in both groups was compared. Eleven articles met the inclusion criteria, and the frequency of GT was statistically associated with psoriasis in ten studies. The pooled odds ratio (OR) was 3.53 (95% confidence interval [CI] 2.56-4.86). There were no significant differences between the presence of GT and the clinical form. However, the Psoriasis Area and Severity Index (PASI) score was statistically higher in patients affected by GT in three of four studies. Psoriatic patients with GT also exhibited less improvement in the PASI score after treatment. One study found an association between GT and a negative impact on patients' quality of life. Nevertheless, age, gender, toxic habits, psoriasis onset and duration of the disease were not clearly associated. The results support the concept of GT as a manifestation of psoriasis. Future research should focus on the repercussions of GT in psoriatic patients, due to the negative consequences on severity and treatment response.

Tratamiento del liquen plano oral. Revisión sistemática y protocolo de actuación / Treatment of oral lichen planus. Systematic review and therapeutic guide

En la presente revisión sistemática se analizaron 55 artículos estructurados sobre la eficacia terapéutica frente al dolor y a los signos clínicos del liquen plano oral (LPO). La búsqueda bibliográfica se elaboró siguiendo los criterios del sistema PRISMA, seleccionando los ensayos realizados mediante alguno de los siguientes diseños metodológicos: entre fármaco (principio activo) vs. mismo fármaco en diferente excipiente o concentración, fármaco vs. diferente principio activo, fármaco vs. fitoterapia y fármaco vs. tratamiento con fototerapia. Basándonos en los resultados se propone un algoritmo que sirva de guía para establecer el tratamiento del LPO en sus formas clínicas atrófica y erosiva. Se destaca el empleo del propionato de clobetasol al 0,025-0,05% de aplicación tópica como primera alternativa terapéutica. En segundo lugar, el tacrolimús al 0,1% y pimecrolimús al 1% también formulado para su pauta tópica. Y, finalmente, se aborda el empleo de corticosteroide sistémico y la aplicación de láser de diodo (AU)

In this systematic review, 55 structured articles on the therapeutic efficacy against pain and clinical signs of oral lichen planus (OLP) were analysed. The literature search was developed according to the criteria of the PRISMA system, selecting the tests performed using one of the following methodological designs: drug (active ingredient) vs. drug in different excipient or concentration, drug vs. different active principle, drug vs. phytotherapy and drug vs. treatment with phototherapy. Based on the results, an algorithm is proposed to guide the treatment of OLP in its atrophic and erosive clinical forms. The use of clobetasol propionate at 0.025-0.05% of topical application as the first therapeutic alternative is highlighted. Secondly, 0.1% tacrolimus and 1% pimecrolimus also formulated for its topical regimen. And finally, we address the use of systemic corticosteroids and the application of diode lasers (AU)
