The decrease of fibroblasts and fibroblast growth factor-2 expressions as a result of X-ray irradiation on the tooth extraction socket in Rattus novergicus

Background: Wound healing involves cellular, molecular, physiological, and biochemical processes as responses to tissue damage. For instance, when a failure during tooth extraction occurs, radiographic examination, X-rays, is required. X-rays as an enforcer diagnosis can damage DNA chain, resulting in cell death and inhibition of wound healing process. Purpose: This research aims to analyze fibroblasts cell number and fibroblast growth factor-2 (FGF-2) expressions during wound healing process after tooth extraction as a result of X-ray irradiation. Methods: There were three research groups, each consisting of ten rats. Incisor tooth extraction was performed on the left lower jaw, and then X-ray examination was conducted at certain irradiation doses, namely 0 mSv, 0.08 mSv, and 0.16 mSv. Those animals were sacrificed on day 3, and on day 7 after the extraction, histopathology and immunohistochemistry examinations were conducted to determine fibroblast cell number and FGF-2 expressions. Data obtained were then analyzed by oneway ANOVA and Tukey HSD tests. Results: The number of fibroblasts decreased significantly in the group with the irradiation dose of 0.16 mSv applied on day 7 after the extraction (p <0.05). Similarly, the number of FGF-2 expressions decreased significantly in the group with the irradiation dose of 0.16 mSv applied on days 3 and 7 after the extraction (p <0.05). Conclusion: X-ray irradiation at a dose of 0.16 mSv can inhibit the healing process of tooth extraction wound due to the decreasing of fibroblasts cell number and FGF-2 expressions

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

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

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
