Effectiveness of Injectable Platelet-Rich Fibrin in the Treatment of Oral Lichen Planus: A Systematic Review and Meta-Analysis.

Oral lichen planus (OLP) is a chronic inflammatory condition affecting the oral mucosa. The current review investigated the potential effectiveness of injectable platelet-rich fibrin (i-PRF) as a treatment for OLP when compared to other interventions. The current review adhered to Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. A comprehensive search strategy was implemented across databases such as PubMed, Embase, Scopus, Web of Science, CINAHL, and Google Scholar. The search utilized a combination of Boolean operators (AND, OR) and Medical Subject Headings (MeSH) terms to capture relevant studies. Comparative clinical studies focusing on i-PRF as a treatment for OLP and other interventions were included. Outcomes assessed were pain, surface area of lesions, and patient satisfaction. Review Manager 5.4 was used for statistical analysis. The Risk of Bias 2.0 (RoB 2.0) tool was used to assess the methodological quality of the studies. Three studies were included for the final analysis. The findings indicated that both the i-PRF and comparison treatment groups demonstrated reductions in pain and lesion size. The post-treatment Visual Analogue Scale (VAS) scores showed a decrease in pain intensity, and there was an improvement in lesion extension in the i-PRF-treated sites. The results also revealed increased patient satisfaction with i-PRF treatment. Adverse effects were not reported or specified in the included studies. Quantitative analysis for pain (VAS) showed a mean difference of 0.38 (95% CI: 0.63-1.40), but there was no significant difference between the i-PRF and control groups at p=0.46. Though intragroup differences showed statistically significant differences between pre and post intervention, intergroup differences were not significant for any of the assessed outcomes. The findings from this study suggest that i-PRF holds promise as a potential treatment for OLP. The use of i-PRF resulted in pain reduction, lesion size improvement, and increased patient satisfaction. However, it is important to consider the limitations of the included studies, such as variability in study designs, small sample sizes, and the limited number of studies.

Knowledge, Awareness, and Interest in Forensic Odontology Among the Dental Teaching Staffs in the Dental Colleges of Jharkhand.

BACKGROUND: Forensic dentistry is a subspecialty of forensic science that handles, examines, and presents evidence from teeth in the most ethical manner possible. In addition to doing research, forensic odontology (FO) entails managing, examining, assessing, and presenting evidence from dentistry in civil or criminal investigations. In these circumstances, the forensic odontologist aids the court system by reviewing the dental findings. AIM: The present investigation was carried out to assess the dental faculty member's awareness, interest, and knowledge of FO at dental educational institutions in Jharkhand, India. METHODS AND MATERIALS: The sample size calculation assumes a simple random sampling technique and a large population size using the formula E=sqrt((Z^2*p*(1-p))/n). A total of 102 dental teaching faculty members from diverse dental specialties participated in the survey. Utilizing a validated questionnaire that was sent directly after receiving approval from the institutional ethics committee in January 2023, data were gathered in a tailored manner. The questionnaire included 12 questions to gauge the dental teaching faculty members' awareness, knowledge, and interest in FO. Closed-ended questions were included. The outcomes were computed using a percentage system. RESULTS: In this study, 95% of study participants agreed with the fact that teeth are a possible source of DNA, while 5% were unaware of this fact. 68% of study participants said that visual examination constitutes the initial stage in the identification process for unidentified bodies while 8% of study participants said that DNA fingerprinting constitutes the initial stage in the identification process for unidentified bodies. However, 8% of study participants didn't know anything about this aspect. 72% of dental teaching faculty members agreed to the fact that Barr bodies should be used to determine sex. 89% of study participants responded positively to the question "Can teeth or enamel serve as a tool for determining age?" 11% of study participants did not know that teeth or enamel can serve as a tool for determining age. 41% of study participants had the correct information that FO instruction for bachelor of dental surgery (BDS) students takes place and, as per Dental Council of India (DCI) standards, should be given in both BDS second and third years. CONCLUSION: The results of the current survey provided information on FO practices among Jharkhand dental institutes' dental faculty. The poll revealed that they have the necessary information, which they must have learned either while studying, participating in continuing dental education, or teaching.

Comprehensive Assessment of Albumin and Uric Acid Levels in Oral Submucous Fibrosis: A Comparative Case-Control Study Involving Different Risk Groups.

Background Oral submucous fibrosis (OSMF) is a premalignant disorder that impacts the oral cavity and pharynx. Major risk factors for OSMF are attributed to the consumption of betel nuts or tobacco. These substances harbor various carcinogens that trigger the production of free radicals and reactive oxygen species. Antioxidants are pivotal in preserving cellular integrity and impeding the oncogenic transformation of body cells. In this context, albumin and uric acid, being primary antioxidants present in body fluids, bestow a defensive effect against this condition. Thus, the present study is designed to elucidate the differential concentration of albumin and uric acid between patient cases and healthy cohorts. Methodology This case-control study was conducted to evaluate the albumin and uric acid levels in individuals diagnosed with OSMF (cases) and compare them with healthy controls for a period of six months. A cohort of 100 individuals was partitioned into four groups, with each group comprising 25 individuals: Group I was made up of healthy individuals; Group II consisted of individuals who chew tobacco and areca nuts but are not affected by OSMF; Group III included individuals who only use tobacco without areca nuts and are afflicted with OSMF; and Group IV comprised individuals who consume a combination of areca nuts and tobacco and are diagnosed with OSMF. Biochemical evaluation was carried out using the BS-380 chemistry autoanalyzer (Mindray, Shenzhen, China), and the quantification of serum albumin and uric acid was performed by the uricase-peroxidase (POD) method with dihydroxybenzene sulfonic acid (DHBS). Results The study cohort of 100 individuals was made up of 70 males and 30 females, with an average age of 42.51 (11.62) years. The comparison of the mean concentration of serum albumin across all groups revealed that healthy controls exhibited the highest serum albumin concentration of 4.284 (0.618), with a statistically significant p-value (0.001) across all groups. A comparison of the mean value of serum uric acid among all groups showed that healthy controls had the highest value of serum uric acid (5.26±1.161), with a considerable p-value (0.001) between all groups. Conclusion The present study concluded that serum biomarkers assessed were high in healthy individuals and consumption of areca nuts, tobacco, and their products was significantly associated with low levels of albumin and uric acid. Therefore, both albumin and uric acid can be used as important biomarkers for uncovering oral premalignant lesions and conditions ahead of time and can also be used in mass screening.

Data on morphometric analysis of anterior teeth from Hazaribag College of Dental Sciences and Hospital,jharkhand.

It is of interest to document data on morphometric (measurement of external form) analysis of maxillary and mandibular anterior teeth collected from a dental set up using mesio-distal (MD) dimension. The mesiodistal dimensions of all permanent anterior teeth (central incisor, lateral incisor and canine) of 25 males and 25 females patients were recorded using digital vernier calipers. Data were charted and statistical analysis was done using Mann Whitney U test. Data shows sexual dimorphism for every tooth between males and females. However, dimorphism was exhibited only in maxillary and mandibular canine, mandibular central incisors, and lateral incisor. Hence,odontometric parameters offer simple, reliable and cost-effective in forensic investigation for recording gender discrimination.

Hidden reservoirs of pathogens in dental settings.

Nosocomial infections are a major concern to both clinicians and health care seekers. Investigations have suggested that laptops & mobile phones may contribute to cross-contamination and can serve as vehicles for infection transmission. Therefore, it is of interest to document the data on hidden reservoirs such as mobile phones and laptops of pathogens in dental settings at the Hazaribag College of dental sciences and Hospital, Jharkhand. The samples were collected from 25 laptops and 25 mobile phones from dentists working in a dental college in Hazaribag city. The samples were collected aseptically using sterile cotton swabs dipped in sterile saline by rotating the swabs on the keyboard surfaces of laptops and mobile phones, inoculated into Brain Heart Infusion broth, vortexed for 1 minute in Fischer Vortex Genie 2 on highest setting & streaked immediately on 5% sheep blood agar plates and were incubated at 37°C for 24 hours aerobically. The isolates were identified based on the colony morphology, colony characteristics and biochemical reactions. The bacterial species isolated were Staphylococcus aureus, Coagulase negative Staphylococcus, Bacillus species, Enterococci, Micrococci, and Pseudomonas etc. Predominant species isolated was Staphylococcus aureus and least was Micrococci. Higher percentage of organisms was found at the Department of Periodontics, Endodontics and least was found in Department of Public Health Dentistry. The percentage and type of organism isolated from keyboards of laptops and mobile phones were similar. Thus, laptops and mobile phones act as vehicles for transfer of potential pathogens associated with dental hospitals. Disinfecting the hands prior to examination of patients and disinfection of laptops and mobiles with alcohol wipes should be done to prevent nosocomial infections.

Identification of Candida albicans by using different culture medias and its association in potentially malignant and malignant lesions.

BACKGROUND AND OBJECTIVE: The present study evaluates the association of Candida albicans with normal control group, potentially malignant and malignant lesions of oral cavity by using two different liquid culture media. MATERIALS AND METHODS: Saliva was collected and biopsy was taken only from those clinically suspected potentially malignant and malignant lesions for histopathological diagnosis. Saliva samples were inoculated for fungal growth in Sabouraud's dextrose agar and culture-positive samples had undergone for Germ tube test. Germ tube-positive samples were further taken for quantification of chlamydospore production in liquid media at 8 and 16 hours. RESULTS: In normal control groups no fungus growth was found; however, potentially malignant and malignant cases showed fungus growth, positive germ tube test and chlamydospore formation. The result also showed rapid and quantitatively more chlamydospore formation in corn meal broth + 5% milk in comparison to serum milk culture media. CONCLUSION: The oral mucosa is compromised in potentially malignant lesions, it can be argued that this species may be involved in carcinogenesis by elaborating the nitrosamine compounds which either act directly on oral mucosa or interact with other chemical carcinogens to activate specific proto-oncogenes and thereby initiate oral neoplasia.

[Stem cell--is there any role in tumorigenic activity]. / Kök Hücre - Tümörijenik Aktivitede Rolü Var mi?

Stem cells are a quintessential key to proper behavior of homeostatic processes. They are often thought of as the solution to a wide range of human conditions, with the ability to rescue malfunctioning or non-functioning organs and tissues. However, there is increasing evidence that stem cells can play a central role in disease. Most recently stem cells have been implicated in cancer after not responding to homeostasic controls such as proliferation and differentiation. Cancer has long been seen as a disease that arises from mutations that impair the capacity of any cell within the organism to respond to the signals that regulate proliferation. Besides their scarcity or abundance, a second important issue with respect to cancer stem cells is their origin. A new defining model for carcinogenesis, the "cancer stem cell hypothesis" was put forward in 2006, according to which cancer is a stem cell disease that places malignant stem cells at the centre of its tumorigenic activity as they have the capacity to undergo self-renewal, and have the potential to differentiate into different types of cells in a specific lineage.
