The association between minor recurrent aphthous stomatitis (RAS), children's poor oral condition, and underlying negative psychosocial habits and attitudes towards oral hygiene

Hematological parameters, obesity, stress and oxidant - antioxidant indicators in patients with or without recurrent aphthous stomatitis: A case control study

INTRODUCTION

Recurrent Aphthous Stomatitis (RAS) is a frequent chronic disease of the oral cavity that affects 5-25 % of the population with a plethora of predisposing factors. Despite its equivocal etiology, immune alterations, hematologic deficiencies and oxidative stress has been reported to be significant etiologic factors. Stress and obesity are other environmental factors that have been studied to understand associations with RAS.

OBJECTIVES

This study investigated the association of stress, hematologic parameters, oxidative indices and other selected salivary factors in a case control study on RAS Methods: Twenty-two participants each in both case and control groups were recruited with saliva and serum samples collected from them after a self-administered Recent Life Changing Questionnaire (RLCQ). OHI-S and salivary flow rate (SFR) were calculated with selected hematologic parameters and oxidative indices such as Total oxidant (TOS) and anti-oxidant (TAS) levels and their ratio - Oxidative Stress Index (OSI). Anti-oxidative indices of Ferric-Reducing Antioxidant Power (FRAP) and Glutathione Peroxidase Activity (GsPHx) were also estimated.

RESULTS

The RAS group had a significantly higher RLCQ scores at a median of 145 more than the control (57.5). There was no significant in their obesity indices, however there was a significant higher mean in the ESR (p< 0.0001) and Vit B12 (p = 0.0001); OHI-S was also significantly higher in the RAS group with a median of 1.65. Both the salivary and serum TOS were significantly higher in the RAS (10.0 ± 3.8, 15.4 ± 8.9) compared to the control group (7.92 ± 1.49, 9.56 ± 3.5). GsPHx activity was significantly higher in both the saliva and serum in the control group (0.08 ± 0.08, 0.19 ± 0.11) while nil significant difference was found in the FRAP activity. Regression showed most important variables to be the salivary GsPHx activity, followed by serum OSI and GsPHx activity.

CONCLUSION

The oxidative indices of TOS, TAS and GsPHx can serve as significant biomarkers in detecting RAS. This further corroborates the role of immune dysregulation in the etiology and predisposition to RAS.

Atorvastatin mucoadhesive tablets in the management of recurrent aphthous stomatitis: a randomized clinical study

BACKGROUND

Aphthous stomatitis is one of the most common oral mucosal diseases. Due to the commonness of recurrent aphthous stomatitis and considering the anti-inflammatory, analgesic, and tissue regenerative properties of atorvastatin and the lack of a study on the effect of statins on minor recurrent aphthous stomatitis, this study investigates the effect of atorvastatin mucoadhesive tablets as a topical treatment on reduction of symptoms and duration of this disease.

METHODS

This study is a randomized, double-blinded clinical trial. Patients were divided into two groups, atorvastatin and, placebo; each of the patients received three mucoadhesive tablets daily in the morning, noon, and night. Finally, the patients were examined on days 0 (baseline), 3, 5, and 7 to determine the diameter of the inflammatory halo. The VAS scale was used to evaluate pain intensity for up to 7 days after each meal. The data was entered into SPSS 24 software and analyzed.

RESULTS

The halo diameter did not significantly differ between the two groups on baseline (P > 0.05). However, on the study's third, fifth, and seventh days, the difference between the two groups was remarkable, so in the atorvastatin group, the size of the lesions decreased in shorter healing time (P < 0.05). In addition, the patient's pain intensity (VAS) also showed a significant decrease in the atorvastatin group except on the first, second, and seventh days of the study (P < 0.05).

CONCLUSION

Atorvastatin mucoadhesive tablets effectively reduce the pain of patients with minor recurrent aphthous stomatitis and reduce the size and healing time of the lesions, so their application should be considered in treating minor recurrent aphthous stomatitis. The present study was approved by the Medical Ethics Committee of Mazandaran University of Medical Sciences with the ethics code IR.MAZUMS.REC.1400.8346. Also, this study received code IRCT20170430033722N4.

Efficacy Ozone Therapy in Reducing Periodontal Disease

The aim of this study is to highlight the properties of ozone as an aid to non-surgical therapy compared to non-surgical therapy alone. This study included thirty Caucasian patients (eighteen women and twelve men) aged between 35 and 65, recruited at the Oral Hygiene and Prevention Center of the Dental Clinic of the Vita-Salute San Raffaele University, at the San Raffaele hospital in Milan. The periodontal probing was recorded with a PC-PUNC 15 manual probe (Hu Friedy) at time 0; the scaling and root planing session was performed at T1 with or without the aid of ozone therapy, and then, the patients were re-evaluated at one month (T2), three months (T3), and six months (T4). The results obtained show that there are not statistically significant differences in terms of reduction in clinical periodontal indices such as plaque, bleeding, and pocket depth between the two groups. Therefore, treatment with ozoral gel would not seem to improve non-surgical periodontal therapy alone. However, clinical periodontal indices significantly improved in patients treated with non-surgical therapy and ozone gel. From this point of view, ozone gel can be used as an aid to non-surgical therapy due to its excellent characteristics, in particular, its powerful virucidal action.

Crosstalk between the oral microbiota, mucosal immunity, and the epithelial barrier regulates oral mucosal disease pathogenesis

Oral mucosal disease (OMD), which is also called soft tissue oral disease, is described as a series of disorders or conditions affecting the mucosa and soft tissue in the oral cavity. Its etiology is unclear, but emerging evidence has implicated the influence of the composition of the oral mucosa and saliva-resident microbiota. In turn, this dysbiosis effects the immune response balance and epithelial barrier function, followed by the occurrence and progression of OMD. In addition, oral microbial dysbiosis is diverse in different types of diseases and different disease progressions, suggesting that key causal pathogens may exist in various oral pathologies. This narrative literature review primarily discusses the most recent findings focusing on how microbial dysbiosis communicates with mucosal adaptive immune cells and the epithelial barrier in the context of five representative OMDs, including oral candidiasis (OC), oral lichen planus (OLP), recurrent aphthous ulcer (RAU), oral leukoplakia (OLK), and oral squamous cell carcinoma (OSCC), to provide new insight into the pathogenetic mechanisms of OMDs.

Confirmatory Factor Analysis of Knowledge, Attitude, and Behaviour Questionnaire towards Oral Health among Indian Adults

Background: Oral health-related conditions are among the common conditions seen in adults in India. The usage of inappropriate measurement tools that are unvalidated may result in deceptive and imprecise findings that might lead to substandard plans for cessation programs and ineffectiveness. This study was conducted to validate a questionnaire that can assess the factor structure of knowledge, attitude, and behaviour towards oral health among adults in India by confirmatory factor analysis. Methods: Simple random sampling was conducted among adults in India. A total of 260 adults participated in this study. The knowledge, attitude, and behaviour (KAB) questionnaire on oral health was circulated among the adults who were willing to participate in the study after it was explained to them, and the questionnaires were retrieved once they completed. Software R version 3.6 was used to analyse the data of this study. Robust maximum likelihood was utilized for the assessment due to the violation of multivariate normality assumption. For attitude and behaviour domain, a three-factor model was used for measurement model validity and construct validity. Results: The confirmatory factor analysis of the three-factor model for the 26-item KAB questionnaire on oral health gave sufficient goodness-of-fit values and the measurement model exhibited ideal convergent and discriminant validity following model re-specification. The three-factor model was tested to obtain measurement model validity and construct validity for attitude and behaviour domains. The results of this study gave a statistically significant value (p < 0.001), with χ² (df) values of 39 (7) and 28 (11) for attitude and behaviour domains, respectively. Conclusions: The KAB oral health questionnaire used in this study has a valid measurement model and reliable constructs. It was found to be an ideal tool to measure the KAB towards oral health among adults in India.

A micromorphological/microbiological pilot study assessing three methods for the maintenance of the implant patient

OBJECTIVE

The aim of this study was to evaluate and compare the effectiveness of the ultrasonic piezoelectric inserts of EMS Steel Tip A, EMS Peek, and IS-TiP-STS-3E© in reducing peri-implant bacterial load without compromising the surface of implants during professional oral hygiene in the follow-up.

MATERIALS AND METHODS

Thirteen implants were examined (Winsix, Biosafin, Ancona, Italy). The implants were divided into five groups and analyzed with a SEM microscope and microbiological analysis to evaluate the possible modification of structure and the bacterial load reduction.

RESULTS

The control and A, B, and C test groups were initially contaminated in vitro with Streptococcus mutans. Subsequently, the A, B, and C test groups were treated by an only expert operator in standard conditions. Test groups A, B, and C were inoculated for 3 hr and, furthermore, microbiologically analyzed.

CONCLUSION

The gold standard of an implant maintenance is a significant reduction of the bacterial load without becoming aggressive. According to our results, despite the limitations of the study, the authors recommend the least aggressive IS-TiP-STS-3E© , but combined with an antimicrobial agent to reduce the bacterial load, because the IS-TiP-STS-3E© did not show appreciable results versus the EMS Peek in reducing the bacterial load.

Frequent and Persistent Salivary Gland Ectasia and Oral Disease After COVID-19

The clinical picture of coronavirus disease 2019 (COVID-19) in various target organs has been extensively studied and described. However, relatively little is known about the characteristics of oral cavity involvement. This is surprising, considering that oral mucosal and salivary gland cells are known targets for the direct replication of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and that the presence of the virus in saliva is a source of transmission of the infection. The aim of our study was to investigate the presence and prevalence of oral manifestations in COVID-19 survivors. We profiled the oral involvement in 122 COVID-19 survivors that were hospitalized and followed up at a single-referral university hospital in Milan, Italy, between July 23, 2020 and September 7, 2020, after a median (interquartile range) time from hospital discharge of 104 (95 to 132) d. We found that oral manifestations, specifically salivary gland ectasia, were unexpectedly common, with oral manifestations being detected in 83.9% while salivary gland ectasia in 43% of COVID-19 survivors. Salivary gland ectasia reflected the hyperinflammatory response to SARS-CoV-2, as demonstrated by the significant relationship with C-reactive protein (CRP) and lactate dehydrogenase (LDH) levels at hospital admission, and with the use of antibiotics during acute disease. Both LDH levels and antibiotic administration survived as independent predictors of salivary gland ectasia at multivariable analysis. Temporomandibular joint abnormalities, facial pain, and masticatory muscle weakness were also common. Overall, this retrospective and prospective cohort study of COVID-19 survivors revealed that residual damage of the oral cavity persists in the vast majority of patients far beyond clinical recovery, and suggests that the oral cavity represents a preferential target for SARS-CoV-2 infection. Further studies are needed to clarify the connection between SARS-CoV-2 infection and oral disorders.

Recent advances in the aetiology of recurrent aphthous stomatitis (RAS)

Recurrent aphthous stomatitis (RAS) is the most common disease of oral mucosa, which almost attacks each individual once in their lifespan. Although plenty of factors have been suggested to play a role in the pathogenesis of RAS, the aetiology of RAS is still controversial, which might lead to limited clinical therapies in accordance with each RAS patient. This review mainly illustrates recent advances in potential causes associated with RAS in detail. Deeper comprehension of the aetiology of RAS will support doctors and researchers to make a better management of RAS patients and to discover new treatments. The aetiology of RAS is complicated, hence we should take a comprehensive view into its aetiology, with multiple potential factors being considered. Sample collection of RAS patients have greatly limited the progress in the aetiology of RAS. A research model of multiagency cooperation can help achieve perfect sample collection of year-round and multiposition.

General Health, Systemic Diseases and Oral Status in Adult Patients with Coeliac Disease

The prevalence of coeliac disease in the general population is 0.5–1%; however, most patients remain undiagnosed until adult age. In some cases, the onset is represented by sub-clinical signs, some of which can be found in the mouth. The aim of this research was to identify any associations between the clinical characteristics of coeliac disease and oral manifestations. A structured questionnaire was administered to a group of 237 individuals with coeliac disease. 100% of the subjects fully completed the questionnaire. Among them, 182 (76.7%) were female, 64 patients (27%) were aged 15 to 24 years, 159 (67%) were aged 25 to 55 and 14 (6%) were aged 56 and over. Significant associations were observed in caries prevalence and dentin sensitivity; in addition, an inappropriate diet was related to oral manifestations; following a gluten-free diet could be important to control the gingival bleeding levels and to manage oral symptoms associated to coeliac disease. In general, the presence of inflammatory symptoms in the mouth seems to be associated with general symptoms of inflammation related to coeliac disease.

Evaluation of the Effectiveness of the Use of the Diode Laser in the Reduction of the Volume of the Edematous Gingival Tissue after Causal Therapy

AIM

The aim of this study was to evaluate and compare two different techniques for the treatment of plaque-induced gingivitis, demonstrating whether the causal therapy supported by diode laser can allow a resolution of the edema caused by gingivitis in less time compared to the single traditional causal therapy.

MATERIALS AND METHODS

Twenty-five patients between 20 and 60 years of age with a specific diagnosis of gingivitis were evaluated at the CLID-HSR oral hygiene department. Once the clinical parameters (bleeding index, plaque index, recession, and clinical attack level) were recorded, each of them was subjected to a professional oral hygiene session and instructed in correct home hygiene procedures. Through a split-mouth protocol for each individual patient, hemi-arches were treated by simple randomization to be treated with causal therapy supported by the action of the diode laser (experimental therapy) and which with traditional causal therapy (control therapy). A first intraoral scan was performed before therapy (T0), which was repeated 20 min after rinsing with CHX. The intraoral scans were repeated at a control 7 (T1) and 14 days (T2) after the session. For each intraoral scan, a volumetric value was calculated, proportional to the edema of the gingival tissues, using special digital software. The operator who carried out the volumetric measurements on the software was not aware of the therapy implemented on each half-arch. The operator who carried out the statistical analysis was not aware of the therapy applied to each group. The collected data were statistically compared in order to detect any differences between the volumetric variations between the two therapy groups and within the therapy groups over time. After evaluating the distribution of data by means of the Kolmogorov-Smirnov statistical test, the appropriate nonparametric tests were chosen to carry out the statistical comparisons.

RESULTS

Based on the analysis of the gingival-periodontal health parameters and the volumetric value of the treated areas, no statistically significant differences were detected between the areas treated with the adjuvant action of the diode laser compared to those treated with causal therapy alone.

CONCLUSIONS

With the limitations of this study, in accordance with the statistical results obtained, diode laser therapy does not allow a faster resolution of gingival edema compared to traditional therapy; the two treatment techniques for plaque-induced gingivitis, therefore, have the same efficacy.

Developmental Enamel Defects (DDE) and Their Association with Oral Health, Preventive Procedures, and Children's Psychosocial Attitudes towards Home Oral Hygiene: A Cross-Sectional Study

Background: Developmental enamel defects (DDE) exert significant effects both on esthetics and occlusal function and prevention should be the general clinical approach to DDE. The purpose of this cross-sectional study was, therefore, to detect, within a pediatric sample, any significant association between DDE and children’s psychosocial attitudes towards home oral hygiene, as well as potential associations between primary preventive procedures and DDE. Methods: 394 schoolchildren (197 males and 197 females, 8.9 ± 1.4 years) underwent an intra-oral examination; they were then interviewed with a brief questionnaire. Results: 5–6% and 12–14% of participants had, respectively at least one molar and one incisor affected by DDE. In general, no associations were observed in the examined clinical categories (caries and other oral health indices). A strong relationship was found between the presence of molar DDE and children’s positive vs. negative psychosocial attitudes towards home oral hygiene. Conclusions: The probability of finding DDE in our sample of examined children was approximately more than doubled for children with negative psychosocial attitudes towards home oral hygiene, than for children with positive attitudes towards home oral hygiene.

Celiac disease and hematological abnormalities in children with recurrent aphthous stomatitis

BACKGROUND

Recurrent aphthous stomatitis (RAS) is one of the most common diseases of the oral mucosa and may be related to vitamin deficiencies or systemic diseases such as celiac disease (CD). The aim of this study was to investigate the frequency of hematinic deficiency and CD in children with RAS.

METHODS

The medical records of patients diagnosed with RAS were reviewed for the presence of hematinic deficiencies (hemoglobin, mean corpuscular volume, ferritin, vitamin B₁₂ , folic acid), and CD. The study group included 108 children with RAS and 57 healthy children who were evaluated for hematological abnormalities in routine evaluation.

RESULTS

The frequency of a family history of RAS was significantly higher in the RAS group compared to the control group (34.2% vs 7%, respectively; P < 0.001). A hematological abnormality was detected in 32.4% of the RAS group and 10.5% of the control group (P = 0.02). The prevalence of iron deficiency anemia was significantly higher in the RAS group (P = 0.037). Three (2.7%) patients with RAS were diagnosed with CD, which is a significantly higher frequency than that observed in healthy children in Turkey (P < 0.01; OR 6.03, 95% CI [2.37, 4.56]). These children had mild malnutrition, iron deficiency, and iron deficiency anemia.

CONCLUSIONS

Children with RAS should be evaluated for nutritional status and hematological indices, and in the case of hematological abnormalities and malnutrition screening for CD should be considered.

Prevalence of Caries and Associated Risk Factors in a Representative Group of Preschool Children from an Urban Area with High Income in Milan Province, Italy

The present survey provides a quantitative assessment of caries prevalence, covering a group of 3–5 year-old children from an urban area generally with a high income in the province of Milan, and a comparison of the obtained results with the data presented by the W.H.O. A cross-sectional study was conducted in the period from March to September 2018 to investigate the prevalence of caries in a sample of 160 children (82 females and 78 males). The absence/presence of caries was defined as a dependent variable. Factors concerning lifestyle, diet, oral habits, oral hygiene, the presence and type of malocclusion and mouth breathing attitude were considered as risk factors. Data were analyzed by Chi-square (χ2) and regression tests using SPSS (version 25.0) software. In total, 84.38% of children (135 out of 160) showed no caries. A regression analysis demonstrated that children who had already received an early first dental visit were mostly those already affected by caries. Furthermore, children who had four meals daily or more were less exposed to the risk of developing caries compared to those who had only 1–3 meals daily. The caries prevalence of preschool children from urban areas with a high income in Milan province is relatively close to that considered acceptable by the W.H.O. in its proposed goals for the year 2020. Therefore, it can be concluded from the obtained results that there is a possibility for further improvement in preventing caries growth at its initial stage: it is necessary for the number of meals daily consumed by children to be controlled by parents, and conducting a dental visit early in childhood must not be neglected.

Oral Hygiene in a Sample of Children/Adolescents Living in Family-Homes from the Province of Milan (Italy): A Pilot Study

Objective: This pilot study is a prospective controlled clinical trial, designed to evaluate the short-term clinical results (the plaque index) of an educational/motivational program for home oral hygiene, directed to children and adolescents who live in family-homes. Methods: The setting of the project was the province of Milan (Italy), where two family-homes were selected. The study group included 26 children (16 females and 10 males) aged between 7 and 15 years, of Italian nationality, from the family-home communities. The control group included 26 children (15 females and 11 males, aged between 7 and 15 years) of Italian nationality, matched for age and gender distribution with the study group, that were not in a socially disadvantaged condition. Collection of the plaque index (PI) was performed at t0. Then, all basic oral hygiene instructions were given to all children/adolescents and their educators. Education and motivation were repeated in the same way after 4–7 weeks (T1), and after 10–12 weeks (T2). The PI was taken also at T1 and T2. Results: An improvement in the PI was generally found in both groups, but there was no statistically significant difference between the two groups over time. Multivariate analysis of variance (MANOVA) revealed a statistically significant effect of time [F (1, 52) = 90.73, p < 0.001], regardless of the assignment group, in consequence of which the plaque index presented a moderate and significant improvement. Conclusion: The present data confirm the validity of the educational/motivational program to improve oral hygiene in children/adolescents, regardless of the assignment group.

Azithromycin-induced Aphthous Stomatitis: A Case Series

BACKGROUND

Azithromycin is one of the most popular antibiotics in current clinical practice. This medication generally considered to be safe and well-tolerated in different demographic populations. Like any other drug, azithromycin use is not without risk and adverse effects. In recent years, cardiovascular accidents have been announced as its major and most important side effect. But azithromycin use can be accompanied with less recognized complications which are significantly discomforting. In this article, we presented a neglected adverse effect of azithromycin in medical literature which is aphthous stomatitis.

METHODS

We detected three cases with this complication in our center during a one-year period. All the accessible clinical data were recorded and PubMed database was explored to assess the relevant literature.

RESULTS

The patients had aphthous stomatitis within 24 hours of the first dose which was healed in about 2 to 3 weeks. Naranjo scoring system showed a probable stage for this adverse drug reaction. There was no such a report in our database search process.

CONCLUSION

It could be stated that aphthous stomatitis is an important adverse effect of azithromycin that can affect the patient's quality of life during therapy and in the majority of cases, it can be neglected by healthcare practitioners.
