Prevalence of Oral Manifestations in COVID-19-Diagnosed Patients at a Tertiary Care Hospital in Kerala.

Background: COVID-19, a pandemic since 2019, is still causing significant healthcare burden across the world. Although the disease primarily presents with respiratory symptoms, a multitude of signs and symptoms may be manifested elsewhere in the body. Aim: This study was to estimate the prevalence of oral manifestations in COVID-19 diagnosed patients and thereby understand the effects of corona virus disease on oral health. Materials & methods: A total of 472 patients were evaluated using a questionnaire and further examined visually using a mouth mirror and a light source.The patients were evaluated for erythema, ulcers, macule, papule, vescicles, bullae or any other abnormal changes within the oral cavity. Results: 103 patients (21%) were found to have oral lesions and 41 (39.8%) of them presented with palatal enanthem which was macular in nature. Candidiasis was noted in 19 (18.4%) patients, ulcer in 4 (3.8%), mucositis in 5 (4.8%), angular cheilitis in 3 (2.9%), white coating on tongue in 25 (24.2%) & depapillated tongue with glossitis in 6 (5.8%). Multivariate analysis was done using logistic regression.Tobacco chewing, malignancies and altered taste sensation were found to be independently associated with oral lesions. Conclusion: The study thus confirms the presence of oral lesions in diagnosed COVID-19 patients prompting healthcare professionals on a multidisciplinary approach towards this novel disease.

What are the main oral manifestations in heart transplant patients? A scoping review.

OBJECTIVE: The purpose of this scoping review is to evaluate the oral manifestations (OM) of heart transplant (HT) patients undergoing immunosuppressive therapy (IT). MATERIAL AND METHODS: A literature search was performed using keywords and MeSH terms related to OM and HT in the Medline/PubMed, Web of Science, Cochrane Library, Scopus, LILACS/BBO databases and in gray literature without language or date restrictions until June 2023. Studies that evaluated HT individuals who used any IT and who reported the occurrence of OM were considered eligible. The results from the search were imported to EndNote Web, and duplicates were removed followed by title/abstract and full-text analysis. RESULTS: A total of 402 nonduplicated studies were found and 13 fulfilled the criteria and were included in the present review: 10 cross-sectional, 2 cohorts, and 1 clinical trial. The most reported OM were periodontal diseases, including drug-induced gingival enlargement (DIGE), gingival bleeding, gingivitis, and periodontitis. Reported in a minority of studies are oral cancer, opportunistic infections (oral hairy leukoplakia and erythematous candidiasis), enamel defects, and burning mouth. CONCLUSION: Considering the methodological heterogeneity of the studies analyzed, DIGE is the most commonly observed oral manifestation in HT individuals.

Oral Lesions and Oral Health-Related Quality of Life in Adult Patients with Psoriasis: A Retrospective Chart Review.

Psoriasis is a widespread chronic inflammatory skin disease, that negatively affects physical and emotional well-being and quality of life, as shown by the generally low Dermatology Life Quality Index (DLQI). Psoriasis is burdened by associated comorbidities and some patients manifest concurrent oral lesions, although the existence of oral psoriasis remains controversial. Psoriasis-specific and nonspecific oral lesions and Oral Health-Related Quality of Life (OHRQoL), self-assessed using the Oral Health Impact Profile-14 (OHIP-14) questionnaire, were retrospectively reviewed in adult untreated psoriasis patients with ≥15 teeth, who were non-smokers and had no dental or periodontal infections. Sample (age, gender, comorbidities) and descriptive variables (Body Surface Area-BSA, Psoriasis Area and Severity Index-PASI, Dermatology Life Quality Index-DLQI, severity of psoriasis, distribution of lesions and predominant involvement, years since diagnosis) were correlated with DLQI and OHIP-14 and compared by baseline DLQI and OHRQoL classes. Charts from 90 participants were included. No oral lesions were detected, and excellent/good OHRQoL was found in 94% of the participants. DLQI scores displayed positive significant associations with PASI and BSA, while OHIP-14 with hypertension and IMID, and age. PASI and BSA were significantly higher in participants with DLQI > 10 and also differed significantly among OHQRoL ranks, as well as mucosal involvement and comorbidities. Specifically, among subjects revealing an Excellent OHQRoL, 92.6% were non-IMID, 75% non-hypertensive, 89.7% non-diabetic subjects, 86.8% of non CVD-subjects.

Oral manifestations in women using hormonal contraceptive methods: a systematic review.

OBJECTIVES: To investigate the oral manifestations in women of reproductive age using hormonal contraceptive methods. MATERIALS AND METHODS: This review is based on the PRISMA statement. A literature search incorporated observational studies from the last 21 years. An investigative question was formulated using the PICO model, studies were selected, and a quality analysis was performed using the modified STROBE guidelines. A bibliometric analysis was performed, and the data were examined. RESULTS: Thirteen articles were included, with the majority evaluating periodontal status. Others analyzed factors such as the presence of alveolar osteitis, oral candidiasis, and salivary microbiome dysbiosis. Ten articles were deemed to have a low risk of bias. CONCLUSIONS: Hormonal contraceptives may increase the risk of alveolar osteitis following tooth extraction and increase the presence of the Candida species in the oral cavity. They also affect the periodontium, such as the frequent development of gingivitis, but do not lead to changes in the salivary microbiome. CLINICAL RELEVANCE: The increasing number of women using hormonal contraceptives and the knowledge that these contraceptives can produce oral cavity alterations underscore the need to evaluate the oral manifestations found in these women.

O uso de drogas e seus efeitos na cavidade oral

Objetivos: Descrever as principais manifestações bucais associadas ao uso das drogas lícitas e ilícitas mais utilizadas atualmente, bem como os cuidados que devem ser tomados durante o atendimento odontológico desses pacientes. Revisão de literatura: Na revisão foi abordada a classificação das substâncias químicas, as principais manifestações orais e os cuidados que o cirurgião-dentista deve ter durante o atendimento odontológico. As substâncias descritas foram álcool, tabaco, benzodiazepínicos, maconha, anfetaminas e cocaína/crack. As complicações de saúde bucal associadas ao abuso de drogas podem resultar da exposição direta dos tecidos orais às drogas durante o fumo ou ingestão, da interação biológica das drogas com a fisiologia normal da cavidade oral e dos efeitos das drogas na função cerebral que resultam em um espectro de comportamentos de dependência, como comportamento de risco, falta de higiene e descuido. Considerações finais: O consumo de substâncias psicoativas, seja a curto ou longo prazo, pode desencadear consequências, tanto na saúde geral como na saúde bucal do usuário. Sob essa perspectiva, o cirurgião-dentista deve estar ciente das manifestações orais e sistêmicas causadas pelas substâncias psicoativas e estar capacitado para diagnosticar, tratar ou também encaminhar o usuário, se necessário, visando um cuidado integral e multiprofissional.

Objective: to describe the main oral manifestations associated with the use of the most commonly used licit and illicit drugs today, as well as the care that should be taken during the dental care of these patients. Literature review: The review covered the classification of chemical substances, the main oral manifestations and the care that dentist should take during dental care. The substances described were alcohol, tobacco, benzodiazepines, marijuana, amphetamines and cocaine/crack. Oral health complications associated with drug abuse can result from direct exposure of oral tissues to drugs during smoking or ingestion, from the biological interaction of drugs with the normal physiology of the oral cavity, and from the effects of drugs on brain function that result in a spectrum of addictive behaviors, such as risk behavior, poor hygiene and carelessness. Final considerations: The consumption of psychoactive substances, whether in the short or long term, can have consequences for both the general health and the oral health of the user. From this perspective, the dentist must be aware of the oral and systemic manifestations caused by psychoactive substances and be able to diagnose, treat or also refer the user, if necessary, aiming for comprehensive, multi-professional care.

Mucocutaneous histoplasmosis as the first manifestation of AIDS.

Immunosuppressed patients can present with opportunistic infections resulting from an intrinsic systemic disease, which easily evolves into more aggressive and less common conditions. This work reports a clinical case of a female patient with histoplasmosis lesions in the nasal and oral mucosa, including pulmonary, hematological, and hepatic impairment, which led to the diagnosis of HIV seropositivity. In the presence of severe immunosuppression, morbidity is increased due to deep fungal infections and their unusual clinical characteristics can make diagnosis difficult. Therefore, it can be very helpful to recognize these clinical characteristics in order to determine early diagnostic interventions. It is important to recognize mucocutaneous manifestations of histoplasmosis because the biopsy of these lesions, and subsequent histopathological analysis, is one of the quickest, safest, and cheapest methods of diagnosis.

Ulectomy in a patient with nephrotic syndrome under investigation for Galloway-Mowat syndrome: a case report.

The aim of this study is to report a case in which a patient with nephrotic syndrome underwent surgery to remove fibrous gum tissue (ulectomy). An 8-year-old patient, diagnosed with early onset nephrotic syndrome due to a mutation in the NUP107 gene, had received a kidney transplant and was therefore taking various medications, including immunosuppressants. On oral examination, the patient was found to have a fibrous gingiva that was preventing the eruption of the upper permanent central incisors. A ulectomy was performed and the gingival tissue was sent for histopathological analysis, which showed normal aspects. The upper right central incisor was seen in the oral cavity 15 days after surgery. A second procedure was carried out to facilitate the eruption of the upper left incisor, which was visualized in the oral cavity 30 days later. In addition, oral manifestations such as maxillary atresia, ogival palate and mouth breathing were observed. Therefore, the role of the dental surgeon in the lives of transplanted children is considered important, as they often take various medications that can affect their oral health. Thus, early diagnosis and effective treatment will be essential to prevent future malocclusions and thus improve the quality of life of these patients.

Oral Manifestations in Pregnant Women: A Systematic Review.

Background: The period of pregnancy is characterized by a multitude of diverse changes that exert a notable impact on the oral cavity of women. During this gestational phase, patients necessitate tailored oral care and specific recommendations to preempt and address potential oral diseases. This systematic review aimed to perform a detailed analysis of the research studies that focused on the oral manifestations observed in pregnant women. Methods: A meticulous search was conducted in the databases Medline, Scopus, and Scielo by employing the following search terms: ((pregnant OR pregnancy)) AND (("oral manifestation*") OR ("oral health")). Articles that were published between 2013 and 2023 and written in English or Spanish and studies that scrutinized oral manifestations in pregnant women and included a diagnosis conducted by a qualified dentist were selected; we excluded articles published before 2013, articles that could not be accessed in full text, studies whose patients were not pregnant women at the time of the study, studies where patients were selected because they had a specific disease, studies where the clinical examination was not performed by a dentist, and articles written in languages other than English or Spanish. Subsequently, the risk of bias in the chosen articles was assessed in accordance with the Strengthening the Reporting of Observational Studies in Epidemiology (STROBE) scale. Results: A total of 20 studies were included in the analysis, following the exclusion and inclusion criteria. These studies were categorized as cross-sectional, cohort, longitudinal, or case-control. Various oral manifestations in pregnant women were examined, with five studies comparing these manifestations with those observed in nonpregnant women. Conclusions: The most prevalent oral manifestations associated with pregnancy encompass dental caries, periodontitis, gingivitis, pyogenic granuloma, and candidiasis. Nonetheless, less common lesions may also emerge during the course of pregnancy.

Oral health challenges in patients with chronic kidney disease: A comprehensive clinical assessment.

Loss of kidney function causes oral manifestations and multiple complications that have implications for dental treatment and patients' systemic conditions. We aimed to determine the clinical condition, epidemiological profile, and incidence of dental caries in patients with chronic kidney disease (CKD). This was an observational, cross-sectional, field study using a quantitative and epidemiological approach. The sample consisted of 45 randomly selected patients with CKD from a total of 114 patients. Data were collected through oral clinical examination, anamnesis, and medical records compiled in a clinical file specially developed for this research. Clinical evaluation was performed, including a Decayed, Missing, and Filled Teeth (DMFT) index examination. Data were analyzed using the Shapiro-Wilk test, Mann-Whitney test, and Spearman's rho coefficient. All analyses were performed using IBM SPSS Statistics software version 20.0, with a confidence interval of 95 % and significance level of 5 % (p < 0.05). The results indicated that CKD is more prevalent in the 5th decade of life, with a slight predilection for men. Oral cavity alterations were observed in 77.8 % of patients. The study population had a very high DMFT index, with a high number of missing teeth and a low number of decayed and filled teeth. Poor oral health in patients with CKD indicates a lack of care that supports the necessity of installing a preventive and therapeutic oral program and a regular follow-up aimed at this group of patients.

Oral and oropharyngeal mucosal lesions: clinical-epidemiological study of patients attended at a reference center for infectious diseases.

OBJECTIVE: To determine the prevalence, epidemiological profile, and clinical characteristics of Oral or Oropharyngeal Mucosal Lesions (OOPML) in patients attended at the Otorhinolaryngology Service of the Evandro Chagas National Institute of Infectious Diseases (INI-FIOCRUZ) from 2005 to 2017. METHODS: Statistical analysis of descriptive data from medical records (gender, age, education level, skin color, origin, smoking, alcoholism, HIV co-infection, time of disease evolution, first symptom, and OOPML location) was performed. RESULTS: Of 7551 patients attended at the service, 620 (8.2%) were included in the study. OOPML were classified into developmental anomalies (n = 3), infectious diseases (non-granulomatous n = 220; granulomatous n = 155), autoimmune diseases (n = 24), neoplasms (benign n = 13; malignant, n = 103), and unclassified epithelial/soft tissue diseases (n = 102). OOPML of infectious diseases (60.5%) and neoplasms (18.7%) were the most frequent. The predominant demographics of patients with OOPML were: males (63.5%), white (53.5%), and those in the fifth to sixth decades of life (43.3%). Local pain (18.1%) and odynophagia (15%) were the most reported first symptoms, and the most frequent OOPML sites were the palatine tonsil (28.5%), hard palate (22.7%), and tongue (20.3%). The median evolution time was three months. CONCLUSIONS: Infectious OOPML were the most frequent, as expected in a reference center for infectious diseases, and thus, they are likely to be less frequent in general care and/or dental services. Underreporting of OOPML is possible, as oral/oropharyngeal examination is often not included in the routine medical examination. Oral cavity/oropharynx examination should be performed by specialists, such as dentists and otorhinolaryngologists, who have the expertise in identifying OOPML, even in incipient/asymptomatic cases. Given the numerous diseases in which OOPML can present, diagnosis could be facilitated by multidisciplinary teams, potentially enabling the early treatment of diseases, and thus, reduce morbidity and improve prognosis. The use of standardized medical records for oral/oropharyngeal systematic examination could provide relevant tools for differential diagnoses and information for new clinical-epidemiological studies. LEVEL OF EVIDENCE: Level 3.

Bibliometric analysis of highly cited papers on oral mucosal lesions in COVID-19: Trends and impact in medical literature.

Objective: Bibliometric analysis of highly cited papers facilitates researchers in formulating strategic research possibilities and addressing gaps in specific domains. In this context, a bibliometric analysis was conducted to identify published papers on "oral mucosal lesions in COVID-19" within medical literature. Methods: A comprehensive search was performed in the Scopus database in July 2023. Relevant articles were retrieved, reviewed, and data for the bibliometric analysis was recorded. Network visualization of authors, countries, and keywords was generated using VOSviewer software. Results: The analyzed articles were published over the last three years, from 2020 to 2023, with the highest output observed in 2021. The citation count for individual papers ranged from 1 to 340, with a mean of 22.325 ± 58.93 citations. A total of 37 journals were involved in publishing papers on this topic, and five authors each contributed three papers. Notably, Brazil made the highest number of contributions with eight papers. Among the 40 papers, 19 were review papers and 16 were articles discussing various aspects of oral mucosal lesions in COVID-19 patients. Additionally, six papers were identified as systematic reviews, designated with a high level of evidence. Conclusions: This study presents a comprehensive bibliometric analysis of papers published on "oral mucosal lesions in COVID-19." The findings will assist researchers in identifying impactful papers, understanding the prevailing research trends, and guiding future research directions in this domain. The insights gained from this analysis can contribute significantly to advancing knowledge and improving patient care in this critical area of study.

Maxillary mucormycosis and aspergillosis in post-COVID-19 patients in Mexico: A case series.

BACKGROUND: Fungal infections, during or as a consequence of SARS-CoV-2 infection, associated with uncontrolled diabetes mellitus and indiscriminate use of corticosteroids have been reported. In the jaw, mostly mucormycosis has been diagnosed in hospitals. METHODS: A retrospective, cross-sectional, descriptive study of the clinical, imaging, and histopathologic characteristics of maxillary invasive fungal infection in post-COVID-19 patients diagnosed in a private non-hospital oral pathology service in Mexico during 2020-2022 was conducted. RESULTS: We found 20 cases of maxillary invasive fungal infections in post-COVID-19 patients, 75% including a diagnosis of mucormycosis and 25% diagnosed as probable aspergillosis. The most common signs and symptoms were exposed necrotic bone followed by tooth mobility, discharge, and pain. On imaging, unilateral maxillary sinus involvement was observed in 6 cases (30%), and bilateral maxillary sinus involvement was observed in 3 cases (15%). CONCLUSIONS: It is essential to consider the association of osteonecrosis of the jaw in post-COVID-19 patients, with aspergillosis, not only mucormycosis, for early diagnosis and appropriate treatment.

Oral Manifestations in Hospitalized and Non-Hospitalized Cuban Patients with COVID-19: A Cross-Sectional Analysis through a Survey

Introduction: COVID-19 continues to drive research aimed at elucidating the disease's behavior and clinical aspects for improved diagnosis. Objective: To describe oral manifestations reported through a survey by dentate and denture-wearing Cuban individuals hospitalized due to confirmed COVID-19 infection. Methods: A cross-sectional descriptive study was conducted through a survey, involving Cuban individuals aged 18 years and above, confirmed COVID-19 positive by PCR. Exclusions encompassed smokers, alcoholics, regular medication users, those with poor oral hygiene, and individuals with pre-existing oral manifestations. A questionnaire was administered to over a thousand individuals, of which 264 met the criteria. Variables related to COVID-19 infection and oral hygiene were assessed. Data were processed using SPSS, adhering to ethical principles. Results: The study comprised 264 participants with an average age of 39.96 years. Xerostomia emerged as the most prevalent oral manifestation (40.2%), followed by mandibular pain, TMJ, or bone pain (18.9%), and non-dental mouth pain (12.5%). Xerostomia was more prevalent in the 35 to 39 age group, while mandibular pain predominated in the 50 to 54 age group. No statistically significant evidence was found for dentate individuals or denture wearers, but significance was observed for those requiring hospitalization, exhibiting painless tongue lesions, single ulcers, and painful tongue lesions. Conclusions: Xerostomia was the most prevalent oral manifestation, followed by mandibular pain, TMJ or bone pain, and non-dental mouth pain. A statistically significant association was noted between the need for hospitalization and certain oral manifestations. The use of dentures was not significantly related to the studied manifestations.

Introducción: La COVID-19 continúa generando interés en investigaciones que buscan esclarecer el comportamiento de la enfermedad y sus aspectos clínicos para facilitar el diagnóstico. Objetivo: Describir las manifestaciones orales informadas por individuos cubanos dentados, con prótesis, que fueron hospitalizados al dar positivo por COVID-19. Métodos: Se llevó a cabo un estudio descriptivo transversal a través de una encuesta con una muestra de individuos cubanos mayores de 18 años, infectados por COVID-19 y confirmados mediante PCR. Se excluyeron fumadores, alcohólicos, usuarios regulares de medicamentos, personas con mala higiene bucal y aquellos con manifestaciones bucales previas a la infección. Se aplicó un cuestionario a más de mil individuos, de los cuales 264 cumplieron con los criterios. Se utilizaron variables relacionadas con la infección por COVID-19 y la higiene bucal. Los datos se procesaron con SPSS, respetando los principios éticos. Resultados: El estudio incluyó a 264 participantes con una edad promedio de 39,96 años. La xerostomía fue la manifestación bucal más prevalente (40,2 %), seguida por el dolor mandibular, ATM o hueso (18,9 %) y el dolor de boca no dental (12,5 %). La xerostomía fue más frecuente en el grupo de 35 a 39 años, mientras que el dolor mandibular predominó en el grupo de 50 a 54 años. No se encontró evidencia estadística significativa para pacientes dentados o portadores de prótesis, pero sí para aquellos que necesitaron hospitalización, con lesiones en la lengua sin dolor, úlceras únicas y lesiones en la lengua con dolor. Conclusiones: La xerostomía fue la manifestación bucal más prevalente, seguida por el dolor mandibular, ATM o hueso, y el dolor de boca no dental. Se observó una asociación estadísticamente significativa entre la necesidad de hospitalización y ciertas manifestaciones bucales. No se encontró significativo el uso de prótesis en relación con las manifestaciones estudiadas.

Dentofacial manifestations in a child with Jalili syndrome.

Jalili syndrome (JS) (MIM#217080) is a rare autosomal recessive disorder with oculo-dental malformations. The clinical phenotype is characterized by the presence of Cone-Rod Dystrophy (CRD) and Amelogenesis Imperfecta (AI). Genetic mechanism entails a mutation in the CNNM4, a metal transporter gene located on Chromosome 2q11.2. A high fluoride concentration in groundwater has also been identified as an epigenetic factor in this syndrome. JS draws the attention of dentists due to its distinct oral manifestations. To the best of our knowledge, this is the first genetically confirmed pediatric case report from the Indian subcontinent emphasizing the clinical and radiographic features of this condition and its management in a 6-year-old child.

Multiple dental caries management of a 5-year-old child with MIS-C: a case report.

The rare hyper-inflammatory condition known as "multisystem inflammatory syndrome in children (MIS-C)" develops after a COVID-19 infection. Providing dental treatment for patients with MIS-C can be very challenging due to the immunocompromised condition found in these patients leading to rapid progression of other infections, including dental caries. Currently, there is a lack of information regarding the dental management of patients with MIS-C. This case report presents the multiple dental caries management in a 5-year-old Cambodian boy with MIS-C in a dental chair unit, without general anesthesia. Despite the challenges this case presented, i.e., the patient's age, hyper-inflammatory condition due to MIS-C, taking several medications, multiple caries lesions, and the language barrier for behavior management, we were able to meet this patient's needs. The patient's dental and physical health were found to be satisfactorily stable with no complications. At the 6-month recall, his overall oral health had dramatically improved. Careful treatment planning along with a multidisciplinary approach is highly recommended in such cases. The important roles of dentists are not only to treat oral infection, but also to approach patients holistically because the body systems are all connected.

Oral Manifestations of Graft vs. Host Disease: A Comprehensive Review for Best Practice in Dentistry.

Graft-versus-host disease (GVHD) is a complication of hematopoietic stem cell transplantation (HSCT). GVHD may also develop following solid transplants or blood transfusions if white blood cells are transferred. GVHD affects multiple organs, including the oral tissues. This pictorial review provides a background of GVHD to dental practitioners, describes the most common oral manifestations of GVHD, and highlights the main treatment modifications needed to deliver dental care to patients with GVHD. A narrative review enriched with clinical data was performed by searching the scientific literature for all articles regarding GVHD and oral manifestations/therapies. All articles without exclusion criteria, except animal tests, were included in the above review. Acute GVHD may manifest in the oral mucosa; however, it often develops immediately following HSCT when routine dental treatment is postponed. Chronic GVHD may manifest in the oral mucosa, the salivary glands, and the musculoskeletal compartment. It may indirectly affect the teeth and the oral flora, putting the patient at risk for infections. Importantly, GVHD poses an increased risk for oral cancer. GVHD has a wide range of oral manifestations, some of which may affect dental treatment.

Estimating the prevalence of oral manifestations in COVID-19 patients: a systematic review.

BACKGROUND: Patients with coronavirus disease 2019 (COVID-19) present with a variety of oral manifestations. Therefore, we conducted a systematic review to estimate the prevalence of oral lesions among COVID-19 patients. METHODS: An extensive literature search of several electronic bibliographic databases (PubMed, Scopus, Science Direct, Litcovid) was conducted to retrieve all articles published in the English language from January 1, 2020 to March 31, 2023 that reported the prevalence of oral manifestations among COVID-19 patients. A meta-analysis of pooled prevalence was performed using Jamovi ver. 2.3 (2022). The I2 and Q statistics were used to assess heterogeneity between studies, and p-values <0.01 were considered statistically significant. RESULTS: In total, 79 studies with data from 13,252 patients were included. The articles were predominantly published in 2020 (n=33), and Italy was the most common country (n=14). Most of the affected patients more than 50 years old and women (56.6%). The most common sites of involvement were the tongue (n=65), followed by the oral mucosa (n=37) and lips (n=19). High heterogeneity was found between studies. The most common oral manifestation was taste alteration, followed by xerostomia and ulceration, showing pooled prevalence rates of 48%, 35%, and 21%, respectively. CONCLUSION: COVID-19 patients show various oral manifestations that may help clinicians identify the disease promptly. Recognition of the signs and symptoms of COVID-19 is critical for an early diagnosis and better prognosis.

Is drug use associated with the presence of periodontitis and oral lesions? A meta-analysis.

PURPOSE: This systematic review investigated whether drug use is associated with the presence of oral lesions and periodontitis. METHODS: A search was performed for studies that analyzed the presence of periodontitis and/or oral lesions in users of crack, cocaine, and/or marijuana in the PubMed, Scopus, and Web of Science databases. Observational studies in English, Spanish, or Portuguese, without limitation of year, age, and sex, were included. Studies that did not evaluate periodontitis and oral lesions according to the eligibility criteria were excluded. Two authors independently performed study selection and data extraction using a standardized form. The risk of bias of studies included in the meta-analysis was assessed using the Joanna Briggs Institute Critical Appraisal Checklist. The meta-analysis included studies that investigated the association of drug use with the outcome. RESULTS: The initial search resulted in 9,279 articles, from which 16 studies with 15,434 participants were included in the review and 8 studies were included in the meta-analysis. Most studies that evaluated periodontitis in drug users and non-users found a positive association in users. Most studies that analyzed oral lesions reported a higher prevalence, association, or risk of oral lesions in drug users than in non-users. A critical evaluation identified a need to improve the control and reporting of confounding factors in studies on this topic. An association was found between periodontitis and the use of crack, cocaine, and/or marijuana (odds ratio [OR], 1.84; 95% confidence interval [CI], 1.04-3.27; P=0.04) and between oral lesions and the use of these drugs (OR, 2.13; 95% CI, 1.58-2.86; P<0.001). CONCLUSIONS: Drug users are more likely to develop oral lesions and periodontitis than non-users. However, the results should be interpreted with caution, considering the heterogeneity and quality of the studies included in the analysis.

Oral Manifestations of Crohn's Disease: A Systematic Review.

Crohn's disease (CD) is a chronic inflammatory intestinal condition that can affect the entire gastrointestinal tract. It is characterized by its clinical heterogeneity and irregularities in its course. The etiology and pathogenesis are not well established, so it is difficult to establish an early diagnosis and an effective treatment plan. The objective of this systematic review was to present a qualitative synthesis of the studies referring to the oral manifestations of CD. This systematic review was carried out following the PRISMA guide. Research was conducted in the Pubmed, Web of Science, Scopus, Scielo, and Cocrahne Library databases on 23 February 2023, and updated on 1 September 2023. Articles published between 2012 and 2023 were selected. Articles that analyzed the oral manifestation of CD patients and met the established search terms. In addition, the quality of all the selected studies was analyzed following the CARE guidelines for case reports and the STROBE scale for observational studies. A total of 19 articles were included in this review that met the inclusion criteria. Regarding the oral manifestation of CD, oral ulcers, angular cheilitis, and gingivitis stand out. Periodontitis and vegetative pyostomatitis were the least representative manifestations. The most prevalent locations were lips, mucosa, and gingivae. Ulcers, gingivitis, and angular cheilitis are the most frequent oral manifestations in patients with CD. Their early identification and possible relationship with the disease are important for an early diagnosis and an adequate treatment plan.
