Efek Pemberian Lactoferrin 10 mg/ml Terhadap Ekspresi Interleukin-8 dan Interleukin 10 Pada Traumatic Ulcer

Ulkus traumatikus merupakan salah satu kelainan dalam rongga mulut yang berbentuk suatu ulser, yang ditandai dengan kehilangan lapisan epitel sampai melebihi membrana basalis, yang dapat terjadi karena trauma fisik (mekanik, termal dan elektrik) atau trauma kimawi (Field, 2003). Penyebab trauma sebagian besar adalah trauma mekanis dengan sebab dan akibat terjadinya ulser yang jelas terlihat. Beberapa ulser terjadi karena trauma yang tidak disengaja yang terjadi pada daerah yang berada di antara gigi seperti bibir bawah, lidah dan mukosa bukal. Bahan kimia penyebab ulser adalah yang bersifat sifat asam dan basa, penyebab lain adalah faktor iritan lokal. Ulserasi intra oral yang terjadi akibat makanan panas jarang terjadi. Selain itu terapi radiasi dan kemoterapi juga dapat menimbulkan ulserasi (Regezi, 2003)

Current Approaches of Salivary Glands Regeneration for Management of Xerostomia and Hyposalivation: A Narrative Review

Background: The salivary glands are the organs that produce saliva and have a role keeping the oral cavity moist and lubricated. Salivary glands regeneration is important for developing treatments on management of xerostomia and hyposalivation because of the irreversible damage of salivary glands. Common causes include aging, polypharmacy, autoimmune disease, including Sjogren's syndrome, and head and neck radiation, in which xerostomia and hyposalivation having a substantial impact on patient health and wellbeing. Purpose: to describe current approach of salivary glands regeneration for management of xerostomia and hyposalivation through narrative review. Review(s): A literature search using Science Direct and PubMed yielded results between 1973 and 2022, and the results were evaluated to identify the most promising approaches and for future research. The keywords of the search strategy were “salivary gland regeneration” and “xerostomia” or “hyposalivation”. Current studies have revealed potential targets in the development of salivary gland regeneration for the management of xerostomia and hyposalivation. Stem cells therapy aims to repair damaged at the cellular level, especially stimulating acini cells, multiplying and differentiating to replace dead or damaged acini cells. Bioengineering is through isolated acini cells cultured on many modified cell line and administration of bioactive compounds. Gene therapy aims to rebuild functional water channels and neutralization of inflammatory mediators. Conclusion: Several approaches of salivary glands regeneration that can be taken are stem cells therapy, bioengineering, and gene transfer

Oral hyperpigmentation as an adverse effect of highly active antiretroviral therapy in HIV patients: a systematic review and pooled prevalence

Human Immunodeficiency Virus (HIV) infects patients via CD4+ cells which are later be destroyed subsequently causing the deteriotation of immune system. HIV generally manifests in the oral cavity as the first indicating sign and a marker of disease progression. HAART medications are used to reduce the incidence of oral manifestations, however it can also generate adverse effects in the oral cavity including oral hyperpigmentation. This review aimed to estimate the prevalence of oral hyperpigmentation which affect individual quality of life as a side effect of HAART.This systematic review applied Preferred Reporting Items for Systematic Review and Meta-Analyses (PRISMA) 2020. Literature search was performed in ScienceDirect, PubMed, and Scopus by combining terms such as highly active antiretroviral therapy, oral manifestation, epidemiology or prevalence published between January 1998 to March 2022.Of 108 articles, eleven articles were included for systematic review and meta-analysis. The pooled prevalence of oral hyperpigmentation in HAART patients was 25% (95% CI: 11%, 38%; I2: 99%). Subgroup analysis based on geographical location showed varied result may be due to the type and duration of HAART used in study population. The most widely used type of ARV was from the NRTI group (n=7) and the study with the shortest duration showed the lowest oral hyperpigmentation prevalence (n=7).There is an increased prevalence of oral hyperpigmentation by the use of HAART. Future study should investigate the correlation between HAART duration and the degree of oral hyperpigmentation

Hyperplasia of Wistar rat tongue mucosa due to exposure to cigarette side-stream smoke

Background: Hyperplasia, a condition whereby an increasing number of cells are produced due to their uncontrolled division, represents a common symptom of carcinogenesis. Cancer is a physical manifestation of cell malignancy resulting from abnormal proliferation. Globally, oral cancer currently constitutes the sixth largest lethal form of the condition. The most common etiology of oral cancer is tobacco of which cigarettes are the most popular related product. The health risks associated with cigarette smoke not only affect active smokers but also individuals who ingest it passively. Sidestream smoke comes from the lighted end of a burning tobacco product such as a cigarette, pipe or cigar and contains nicotine and many harmful cancer-causing chemicals. Inhaling sidestream smoke increases the risk of lung and other types of cancer. Purpose: The purpose of this study was to understand how sidestream cigarette smoke initiates precancerous changes, in this case hyperplasia, in the oral mucosa epithelium of Wistar rats. Methods: The subjects were divided into three groups, a 4-week treatment group (P1), an 8-week treatment group (P2), and a control group (K), each consisting of ten subjects. The subjects were exposed to a daily two-cigarette dose of smoke. The experiment used a post-test only control group design. All samples were sacrificed during the fourth and eighth weeks. Haematoxylin-eosin staining was performed on the tongues of the Wistar rats to establish the presence of hyperplasia. Data was analyzed using a one-way ANOVA test. Results: After the Wistar rats had been exposed to cigarette smoke, an increased degree of epithelial cell proliferation (hyperplasia) showed a significant difference with a p-value <0.05 during the eighth week. Conclusion: Exposure to cigarette sidestream smoke induces increased epithelial cell proliferation (hyperplasia) in Wistar rats

Stress-induced Oral Lichen Planus Immunopathogenesis and Potential Therapy: A Narrative Review

Background: Oral lichen planus is a chronic inflammatory condition that only involves in the oral cavity and is mediated by the cellular immune system. The etiology of OLP is unclear but autoreactive T lymphocytes are considered to play an important role in the development of OLP. Factors like stress and psychological anxiety have been associated with OLP but their roles in the development of OLP is yet explored. Purpose: To describe stress-induced OLP immunopathogenesis and therapeutic potential. Reviews: In the early stages, the mechanism of OLP involves the expression of keratinocyte antigens or exposure to an antigen in the form of self-peptide or heat shock protein (HSP). HSP90 is the most expressed heat shock protein in the basal layer of keratinocytes and plays a role in recruitment of cellular immune cells through the production of cytokines due to TLR2/4 and CD91 activation, inflammatory cell migration due to 4 integrin activation, and increased antigen presentation due to HSP90-peptide binding to MHC class I/II. Stress as a physiological response triggers the release of the hormone cortisol from the adrenal cortex and catecholamine hormones such as epinephrine/ adrenaline and norepinephrine/noradrenaline from the adrenal medulla. Catecholamines increase the migration of T lymphocyte cells through the interaction of integrins and integrin ligands on the endothelium through the expression of 2-integrin after binding to adrenergic receptors on the cell membrane. Conclusion: Oral lichen planus is a chronic inflammatory condition caused by various factors where stress increases the migration of T lymphocyte cells on the side that expresses self-peptides and antigens through the interaction of immune cells with catecholamines. Topical nonselective beta blockers can be supporting therapy in reducing pain and size of OLP lesions

Oral field cancerization: Genetic profiling for a prevention strategy for oral potentially malignant disorders

Background: Oral cancer therapy, such as radiation or surgical treatment, has pernicious long-term effects that patients suffer throughout their life, the disability being considerable with delayed diagnosis. It is well known that many oral cancers develop from oral potentially malignant disorders (OPMDs). Patients diagnosed with OPMDs may have an increased risk of developing cancer anywhere in the oral cavity. Early detection and intervention could be essential prevention strategies to inhibit oral cancer progression. OPMDs may not immediately develop into carcinoma. However, this condition provides a “field” of specific abnormalities wherein evolving altered genetic cells can be explained with the “field cancerization” concept. Purpose: This review aims to describe the “field cancerization” concept in oral cancer and OPMD, which is expected to contribute to a better clinical management strategy for oral cancer prevention. Review: “Oral field cancerization” describes oral cancers that develop in multifocal areas of pre-cancerous changes. It can be found as histologically abnormal tissue surrounding the tumor, suggesting that oral cancer often consists of multiple independent lesions. Conclusion: The oral field cancerization concept should prompt healthcare professionals to remind their patients that frequent oral examination with histological studies and molecular testing is mandatory for those at high risk of developing malignancies

Knowledge of orofacial pain in students of the Dental Professional Program Faculty of Dental Medicine, Universitas Airlangga

Background: Orofacial pain is associated with the hard and soft tissues of the head, face, and neck. Knowledge of orofacial pain helps in getting information on clinical symptoms, trigger factors, and risks of orofacial pain, as well as clinical and supportive examinations for identifying the pain. The dental professional students’ knowledge influences the ability to diagnose and decide on an appropriate treatment plan. This knowledge is seen from the intelligence level in obtaining information about orofacial pain. Purpose: To describe the level of knowledge of orofacial pain in the students of the Dental Professional Program, Faculty of Dental Medicine, Universitas Airlangga, based on intelligence level. Methods: This research was a descriptive study. Data was taken using a questionnaire on google form with a simple random sampling data technique and was analyzed using SPSS version 25. Results: The majority understand the general description of postherpetic neuralgia (PHN), as well as the risk factors and triggers (93.4% and 87.8%, respectively) associated with it. Further, 90.6% understand burning mouth syndrome (BMS) and the clinical symptoms of PHN. BMS based on clinical examination and support is understood by 96.1%, and 82.9% know how to manage trigeminal neuralgia (TN). Intelligence level is divided into three categories, namely source of knowledge (55.8% are from lectures, journals, and textbooks), material repetition (77.3% never repeated), and retention of material (65.2% no retention). Conclusion: Students’ knowledge of orofacial pain is good, but the relationship between the level of intelligence and knowledge is not yet known

Distilled liquid smoke coconut shell attenuates the cytokine profile of macrophages in oral ulcer in experimental model of diabetes mellitus

The effects of distilled liquid smoke coconut shell (DLS-CS) on the macrophages and nuclear factor erythroid- 2-related factor 2 (Nrf2) and cytokine profiles, that is, tumor necrosis factor α (TNF-α), interleukin-6 (IL-6), and interleukin-1β (IL-1β), were analyzed in oral ulcer tissues affected by diabetes mellitus. Wistar rats were injected with alloxan to create diabetes mellitus, and an oral ulcer was made in the inferior labial fornix mucosa. The rats were treated with DLS-CS 20 µl/20 g body weight, topically, once a day for 3, 5, and 7 days. The Nrf2, TNF-α, IL-6, and IL-1β profiles were analyzed with immunohistochemistry staining and the macrophage count with hematoxylin-eosin staining. The Nrf2 profile was increased after 5 days of treatment and the IL-1β profile was consistently decreased (p < 0.05). The IL-6 profile started to decrease after 5 days, while the macrophages increased after 3 and 5 days. No significant difference was found in TNF-α expression. DLS-CS proved effective in decreasing IL-6 and IL-1β profiles as well as increasing Nrf2 and macrophage migration in oral ulcers with diabetes mellitus
