UNLABELLED
Oral mucositis (OM) is a frequent complication in cancer patients who are undergoing chemotherapy or radiotherapy. It manifests as an inflammation of the oral mucosa, sometimes provoking severe consequences such as eating limitations, difficulty in speaking, and possibly superinfection.
AIM
The aim of this review was to update the evidence published during the last five years on the treatment of oral mucositis induced by radiotherapy and/or chemotherapy in patients with cancer.
MATERIALS AND METHOD
A search was conducted in Pubmed, Scielo and Scopus, using the search terms mucositis, stomatitis, therapy, treatment, oral cancer, oral squamous cell carcinoma, head and neck cancer and head and neck carcinoma, with Mesh terms and free terms, from 2017 to January 2023. The systematic review was conducted in accordance with the PRISMA guidelines.
RESULTS
A total 287 articles were retrieved, of which 86 were selected by title and abstract, and 18 were included after full-text analysis. The most frequently assessed variables were OM severity, pain intensity and healing time. Treatment types were diverse, and included drugs, mouthwashes, medicines based on plant extracts, cryotherapy and low-intensity laser therapies.
CONCLUSION
Dentoxol mouthwashes, Plantago major extract, thyme honey extract, zinc oxide paste, vitamin B complex combined with GeneTime, and the consumption of L-glutamine are effective in diminishing the severity of OM. Pain intensity was lower with doxepin mouthwashes and diphenhydramine-lidocaine-antacid mouthwashes.

Meta-Analysis
CONTEXT
Ulcerative colitis (UC) is a chronic disease affecting the large intestine. Cytokines, as inflammatory mediators, can enable pathological injury of the intestinal mucosa and play an important role in UC's pathogenesis. Traditional Chinese medicine (TCM) offers a wealth of theory and experience in UC's treatment.
OBJECTIVE
The literature review and meta-analysis intended to examine TCM's effects in the treatment of UC patients who have the dampness-heat syndrome on the serum cytokines known to be related to UC's pathogenesis.
DESIGN
The research team conducted a comprehensive literature search for randomized controlled trials (RCTs) in seven databases. The search covered all publicly published documents from the establishment of a database until August 31, 2021. The team also performed a meta-analysis of the RCTs' results to compare the levels of cytokines in the intervention and control groups.
SETTING
The study took place at Yueyang Hospital of Integrated Traditional Chinese and Western Medicine of Shanghai University of Traditional Chinese Medicine in Shanghai, China.
INTERVENTIONS
For the meta-analysis, the research team created two intervention groups, the oral TCM only group and the TCM+ Western Medicine (WM) group and a control group, the WM group. The team determined which RCT's measured a particular cytokine and which groups those RCTs compared, the team examined the differences between the groups postintervention.
OUTCOME MEASURES
The primary outcome measures were the RCTs' levels of 13 serum cytokines-interleukin 6 (IL-6), IL-8, tumor necrosis factor alpha (TNF-α), IL-17, IL-23, interferon-gamma (IFN-γ), IL-21, IL-1, IL-1β, IL-2, IL-4, IL-10, and IL-13. The team used the random effects model to combine the results for the serum markers as standardized mean differences (SMDs) and compared the two intervention groups to the control group.
RESULTS
The research team identified 22 studies that included 1957 participants. The team found that six proinflammatory cytokines were significantly lower in the combined TCM only and TCM+WM intervention groups than in the WM control group: (1) IL-6-SMD -2.60, 95%CI -3.37 to -1.83, P < .00001; (2) IL-8-SMD -2.49, 95%CI -3.34 to -1.64, P < .00001; (3) TNF-α-SMD -1.70, 95%CI -2.07 to -1.33, P < .00001; (4) IL-17 (TCM+WM group only)-SMD-2.99, 95%CI -4.66 to -1.31, P = .0005; (5) IL-23 (TCM+WM group only)-SMD -2.43, 95% CI -2.78 to -2.08, P < .00001; and (6) IFN-γ-SMD -1.47, 95% CI -1.81 to -1.12, P < .00001. The team found that two anti-inflammatory cytokines were significantly higher in the intervention group than in the control group: (1) IL-4-SMD 1.45, 95% CI 0.92-1.99, P < .00001, and (2) IL-10-SMD 1.33, 95% CI 0.97-1.69, P < .00001. For the results that the team couldn't combine, the levels of the proinflammatory cytokines IL-1, IL-1β, IL-2, and IL-21 were significantly lower in the combined intervention groups than in the control group (P < .05), and the level of the anti-inflammatory cytokine IL-13 in the intervention group was significantly higher than that in the control group (P < .05). The comprehensive analysis showed that oral TCM or a combination of TCM and WM could more significantly reduce the levels of the proinflammatory cytokines IL-6, IL-8, TNF-α, IL-17, IL-23, IFN-γ, IL-21, IL-1, IL-1β and IL-2 and increase the levels of the anti-inflammatory cytokines IL-4, IL-10 and IL-13.
CONCLUSIONS
Oral TCM or TCM+WM can reduce the proinflammatory response and increase the anti-inflammatory response of UC patients by regulating serum cytokines and can obtain a better clinical effect than WM only. These benefits can alleviate intestinal inflammation in patients and have a positive effect on clinical efficacy. In the future, more high-quality, large-sample, and long-term follow-up randomized controlled trial are necessary to support research analysis.

Review
: Gaucher disease (GD) is a lysosomal storage disorder with the genetic autosomal recessive transmission. Bone involvement is a prevalent finding in Gaucher disease. It causes deformity and limits daily activities and the quality of life. In 75% of patients, there is bone involvement. This review aims to evaluate the principal findings in the jaw by a Cone-beam computed tomography (CBTC) and X-ray orthopantomography; : PubMed, Web of Science, Lilacs and Scopus were systematically searched until 31 December 2022. In addition, a manual search was performed using the bibliography of selected articles and a Google Scholar search. Clinical studies were selected that considered principal radiographic findings in radiography in a group of patients affected by GD. : Out of 5079 papers, four studies were included. The main findings are generalized rarefaction and enlarged narrow space, anodontia. : The exact mechanism of bone manifestation is probably due to the infiltration of Gaucher cells in the bone marrow and, consequently, the destruction of bone architecture. All long bones are a potential means of skeletal manifestation. The jaw is more affected than the maxilla, and the principal features are cortical thinning, osteosclerosis, pseudocystic lesions, mental demineralization, flattening in the head of the condyle, effacement of anatomical structures, thickening of maxillary sinus mucosa. The dentist plays a crucial role in diagnosing and treating these patients. Sometimes the diagnosis can be made by a simple panoramic radiograph. All long bones are affected, and the mandible is particularly involved.

Review
BACKGROUND
Waterpipe tobacco smoking (WTS) is an issue all over the world, although it is particularly prevalent in the Middle East, and Southeast Asia. The genotoxic effects of smoking were reported to be associated with nucleus abnormalities such as micronuclei (MN), karyorrhexis (KR), karyolysis, pyknosis, binucleates, broken eggs, condensed chromatin in exfoliated buccal mucosal cells, and was believed to be associated with apoptosis of cells and was not correlated to the exposure time.
AIM
The aim of this study was to evaluate and compare the cytotoxic and genotoxic effects of cigarette and WTS on buccal mucosa.
MATERIALS AND METHODS
The pertinent search was done through the computerized literature on MEDLINE, EMBASE, and PUBMED databases, which included case-control, clinical and observational studies regarding the mutagenic effects of cigarettes and WTS in oral tissues. The retraction of data in this study was undertaken from May 2010 to May 2022. A total of 60 articles from the search data were retrieved. This investigation was registered with the research center of Riyadh Elm University for institution review board approval (IRB) and obtained the IRB number "FRP/2021/448/733/707 and the systematic review registration number with respect to PROSPERO is 345417.
RESULTS
After the removal of duplicates, 32 were evaluated for the inclusion and exclusion criteria. Out of 32 articles, twenty studies were evaluated for cytogenetic abnormalities in buccal mucosal cells of waterpipe tobacco smokers (WTS) and cigarette smokers, and 12 were excluded. The mean MN levels in the oral tissues of WTS were more (1.94 ± 0.39) than in non-smokers (1.68 ± 0.35).
CONCLUSION
Therefore, we conclude that the MN count can be employed as a biomarker and preliminary signal for the identification of changes in oral mucosa among smokers, which develop towards cancer formation.

UNLABELLED
The histopathological investigations of oral lesions are a basic approach for diagnosing ongoing cancer or pre-cancer associated pathological attributes in the dissected biopsy. The early detection and management of potentially malignant disorders of the lip and oral cavity that require intervention may reduce malignant transformations, or in case any malignancy is detected during surveillance, the appropriate treatment may improve survival rates. This would guide the clinicians to decide the appropriate treatment modality or lesion to achieve a more favorable prognosis. MCM2 protein is involved in DNA replication providing additional information about the prognosis of neoplasms. Some authors have pointed out that MCM proteins have been inversely correlated with salivary tumour differentiation and therefore could be an indicator of proliferation potential. Therefore, it is essential to find the expression of the MCM2 gene in oral leukoplakia and oral squamous cell carcinoma. Electronic databases like Ebscohost, Livivo, Google Scholar and PubMed were searched. Based on the inclusion and exclusion criteria, 2 reviewers (MS and SN) independently selected the relevant articles. Any disagreement was discussed until a consensus was reached. We used the QUADAS-2 tool to assess the quality of the included studies over four key domains: patient selection, index test, reference standard and flow and timing of participants through the study. 10 out of 57 titles were found to meet the eligibility criteria. Biopsied tissue with immunohistochemical staining or advanced diagnostic studies were included. A total of 901 samples were included in the study and different groups were normal oral mucosa (NOM), oral epithelial dysplasia (OED) and oral squamous cell carcinoma (OSCC). MCM2 proteins are useful diagnostic markers for distinguishing malignant from benign epithelial dysplasia and for early detection and diagnosis of OSCC as an adjunct to clinicopathological parameters.

Review
CONTEXT
Oral mucosa graft (OMG) and penile skin flap (PSF) are common substitutions in urethroplasty; however, the recommended substitution for anterior urethral strictures remains uncertain.
OBJECTIVE
To compare the efficacy of OMG and PSF in anterior urethral strictures in terms of success rate and prevalence of postvoid dribbling based on current studies.
EVIDENCE ACQUISITION
A systematic review was conducted following the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) and registered at PROSPERO (ID: CRD42022313879). All publications until March 1, 2022, were searched in the PubMed, EMBASE, and Cochrane Library databases without any restriction. Studies that focused on patients with anterior urethral strictures undergoing single-stage augmentation urethroplasty with OMG and PSF, and reported comparable success rates between the two substitutions were included.
EVIDENCE SYNTHESIS
Thirteen studies involving a total of 1216 patients were included in the screening procedures, and 12 studies were eventually included in the meta-analysis. No significant difference in success rates was identified between OMG and PSF (odds ratio [OR]: 1.41, 95% confidence interval [CI]: 0.96-2.07, = 0.08). No significant difference was observed in the comparison of success rates in penile urethral strictures (OR: 0.95, 95% CI: 0.53-1.70, = 0.86) and in the comparison of postvoid dribbling (OR: 0.59, 95% CI: 0.31-1.11, = 0.10). However, a subgroup analysis suggested that OMG had a higher success rate than PSF in studies with the top 50% sample size (six studies, OR: 1.678, 95% CI: 1.055-2.668, = 0.029) and the top 50% follow-up period (five studies, OR: 2.279, 95% CI: 1.193-4.352, = 0.013).
CONCLUSIONS
OMG provides the same success rate and postvoid dribbling as PSF. However, based on the existing evidence, OMG is more likely to perform better in a cohort with long-term follow-up and a relatively large sample size. More studies on the two substitutions are necessary to evaluate the factors of urethroplasty success rate, performance of substitutions in penile urethral strictures, and indicators of quality of life.
PATIENT SUMMARY
In this research, we compared the outcomes of oral mucosa graft (OMG) and penile skin flap for urethroplasty in anterior urethral stricture patients in 13 studies. We found that these were similar in terms of success rate and postvoid dribbling. However, OMG could probably provide a higher success rate when the studies had more patients or a longer follow-up period.

Review
Temporomandibular disorders (TMDs) occur frequently within the general population and are the most common non-dental cause of orofacial pain. Temporomandibular joint osteoarthritis (TMJ OA) is a degenerative joint disease (DJD). There have been several different methods of treatment of TMJ OA listed, including pharmacotherapy among others. Due to its anti-aging, antioxidative, bacteriostatic, anti-inflammatory, immuno-stimulating, pro-anabolic and anti-catabolic properties, oral glucosamine seems to be a potentially very effective agent in the treatment of TMJ OA. The aim of this review was to critically assess the efficacy of oral glucosamine in the treatment of TMJ OA on the basis of the literature. PubMed and Scopus databases were analyzed with the keywords: (temporomandibular joints) AND ((disorders) OR (osteoarthritis)) AND (treatment) AND (glucosamine). After the screening of 50 results, eight studies have been included in this review. Oral glucosamine is one of the symptomatic slow-acting drugs for osteoarthritis. There is not enough scientific evidence to unambiguously confirm the clinical effectiveness of glucosamine supplements in the treatment of TMJ OA on the basis of the literature. The most important aspect affecting the clinical efficacy of oral glucosamine in the treatment of TMJ OA was the total administration time. Administration of oral glucosamine for a longer period of time, i.e., 3 months, led to a significant reduction in TMJ pain and a significant increase in maximum mouth opening. It also resulted in long-term anti-inflammatory effects within the TMJs. Further long-term, randomized, double-blind studies, with a unified methodology, ought to be performed to draw the general recommendations for the use of oral glucosamine in the treatment of TMJ OA.

Meta-Analysis
This study aimed to investigate the effect of the lack of keratinized mucosa on the risk of peri-implantitis, while also accounting for possible confounding factors. A literature search was conducted in PubMed and Scopus, including human studies that assessed the presence and width of keratinized mucosa in relation to the occurrence of peri-implantitis. Twenty-two articles were included, and 16 cross-sectional studies we meta-analyzed. The prevalence of peri-implantitis was 6.68-62.3% on patient-level and 4.5-58.1% on implant-level. The overall analysis indicated that the lack of keratinized mucosa was associated with a higher prevalence of peri-implantitis (OR = 2.78, 95% CI 2.07-3.74, p < 0.00001). Similar results were shown when subgroup analyses were performed, including studies with a similar case definition of peri-implantitis (Marginal Bone Loss, MBL ≥ 2 mm) (OR = 1.96, 95% CI 1.41-2.73, p < 0.0001), fixed prostheses only (OR = 2.82, 95% CI 1.85-4.28, p < 0.00001), patients under regular implant maintenance (OR = 2.08, 95% CI 1.41-3.08, p = 0.0002), and studies adjusting for other variables (OR = 3.68, 95% CI 2.32-5.82, p = 0.007). Thus, the lack of keratinized mucosa is a risk factor that increases the prevalence of peri-implantitis and should be accounted for when placing dental implants.

Meta-Analysis
OBJECTIVE
This systematic review (SR) with meta-analysis aimed to evaluate the frequency of micronuclei in the oral mucosa exfoliated cells after cone-beam computed tomography (CBCT) examination.
METHODS
We performed language-independent computer-assisted data searches using PubMed databases, Cochrane, Embase, Web of Science all databases, and Google Scholar. The literature on micronucleus (MN) frequency of clinical trials before and after CBCT examination was included. The frequency of MN in exfoliated cells of the human oral mucosa was the primary outcome of the study. All statistical analyses were performed with R (version 4.1.0), RStudio (version 2022.02.2 + 485) software, and Meta packages (version 5.2-0). Two reviewers independently assessed the quality of the included studies by the EPHPP (Effective Public Health Practice Project) Modified scale with minor modifications. The heterogeneity of the data was analyzed using I statistics, in which I > 50% was considered substantial heterogeneity.
RESULTS
A total of 559 articles were selected through the search strategy. After screening titles and abstracts, nine full-text manuscripts were assessed for eligibility, and six observational studies were included in the meta-analysis. The present study showed a significant increase in MN frequency of human oral mucosal exfoliated cells 10 days after CBCT examination compared to baseline (SMD = - 0.56, 95%-CI = - 0.99 ~ - 0.13, p = 0.01). Because of the high heterogeneity among the studies (I = 72%), after removing one study that was the main source of heterogeneity, excluding the study (I = 47%), the common-effect model was chosen, and the meta-analysis also showed that the frequency of MN in human oral mucosa exfoliated cells increased significantly 10 days after CBCT examination (SMD = - 0.35, 95%-CI = - 0.59 ~ - 0.11, p = 0.004).
CONCLUSION
This review suggested that CBCT examination increases the frequency of micronuclei in oral mucosal exfoliated cells.

Review
The objective of this systematic review was to investigate the expression of angiotensin converting enzyme 2 (ACE 2) in the head and neck region. We examined the evidence of the association of ACE 2 expression in oral tissues, salivary glands, and head and neck carcinoma. We searched Pub Med/Medline, Biorxiv, and Google Scholar to identify relevant literature. Studies reporting ACE 2 expression in human oral tissues and with a focus on head and neck carcinoma samples were included. From 110 studies, we extracted 15 studies analyzing the distribution and expression of ACE 2 in different head and neck tissues - olfactory mucosa and nasopharynx n=5, oral mucosa n=5, salivary gland n=5, head and neck squamous cell carcinoma patients n=3. ACE 2 was found to be expressed at a 4.43-fold increase in the head and neck region (OR, 4.43; 95% CI, 3.76-5.22; I= 97%, P=<0.00001) when compared with controls (other tissues except for head and neck region). RNA expression of ACE 2 was 60% higher in head and neck squamous cell carcinoma patients than that in the normal tissues (OR=0.60, 95% CI, 0.04-9.26, P=0.00001). In conclusion, the meta-analysis of the studies indicated that ACE 2 is highly expressed in olfactory mucosa, nasopharynx, oral mucosa, and salivary glands. Furthermore, the results indicate that ACE 2 expression is increased in patients with head and neck cancer.
