Palatal Rugoscopy: A Tool for Ethnicity and Gender Identification Among Saudi and Kuwaiti Populations.

Background The establishment of human identity has always been a concern after mass disasters, and the role of odontology in forensics has greatly evolved. Nowadays, palatal rugoscopy is a widely used method in the recognition of human identity due to its uniqueness in the course, direction, length, form, position, and enduring nature against disintegration. Its easy applicability, cost-effectiveness, and prompt results can be applied to festering, scorched bodies and in the absence of missing upper limbs and fingers. This study was undertaken to evaluate palatal rugoscopy as a tool to recognize human identity and gender between two different ethnic populations. Methodology A cross-sectional comparative study was conducted in the Department of Oral Maxillofacial Surgery and Diagnostic Sciences, Riyadh Elm University, Riyadh, Saudi Arabia, to recognize ethnicity and gender among the Saudi and Kuwaiti populations. A total of 364 participants were selected from the outpatient department between September 2022 and December 2022. All 364 participants were distributed into two groups after the application of inclusion and exclusion criteria. After obtaining informed consent from all study participants, study models were prepared for final interpretation. The outlining of rugae was done with the help of a sharp graphite pencil, and the assessment of various parameters, including total number, length, direction, unification, and shape of rugae, was done. A comparison was made between the two populations. SPSS version 26.0 (IBM Corp., Armonk, NY, USA) was employed to assess variations in the mean values of both the total number and the distribution of rugae on the right and left sides across different ethnic groups and genders. Results In this study, a total of 364 participants were included. Of the total participants, 184 were Saudis and 180 were Kuwaitis, with 188 males and 176 females. A comparative evaluation of rugae among ethnic groups showed that Saudi participants had a mean number of 8.92 ± 0.660 palatal rugae, whereas in Kuwaiti participants it was 8.68 ± 0.649 (p = 0.001). When rugae length was assessed between genders among Saudi participants, it was found that the majority of participants had primary rugae with a length of more than 5 mm, and the difference was statistically significant (p = 0.002). The majority of Saudi males had forwardly positioned rugae, while the majority of Saudi females had more backwardly placed rugae. When rugae length was assessed in males and females among Kuwaiti participants, it was found that males had more primary rugae than females. This study found that the majority of Kuwaiti males had a wavy shape of rugae, while the majority of Kuwaiti females had more straight rugae. Conclusions This study concluded that among the two ethnic groups, the total number, length, direction, unification, and shape of rugae were different between genders, with significant differences in some parameters. Therefore, palatal rugoscopy might be useful as a tool to recognize gender and ethnicity and may provide better results when used as an additional tool along with other dependable forensic tools.

The commercially available oral rinse vs. curcumin photosensitizers in an artificial mouth model mimicking their use after meals on early colonizers single species biofilm: An in vitro study.

BACKGROUND: Commercially available oral rinses contain active ingredients with concentration that is claimed by manufacturers to be effective as antiplaque agent. To date there has been no mention of the effect of oral rinse on the adherence of early plaque colonizers in plaque formation and the concentration to be used before/after meals. OBJECTIVE: The chief aim of the study was to evaluate microbial retention on the salivary pellicle on treatment with oral rinses (CHX & EO)/PS (mimicking after meals use of mouth wash/PS). METHODS: Noordini's Artifical Mouth model was used for developing the single species biofilm with early microbial colonizers of oral biofilm (A. viscosus, Strep. mitis and Strep. sanguinis respectively). The microbial retention on use of oral rinses comprising of CHX and EO as an active ingredients respectively was compared with Curcumin PS. For evaluating the microbial retention, the pellicle with microbial inoculation was developed on the glass beads in the mouth model. Subsequently the respective single specie biofilm was exposed to the mouth wash and PS after inoculation. It mimicked as use of mouth wash/PS after meals. The bacterial count in the dental biofilm was evaluated on serial dilution (CFU/ml). Sterile deionized water was used as a negative control. For qualitative analysis, Scanning electron microscope (SEM) was used to evaluate the microbial count. RESULTS: From the data it was observed that for the treatment of single species experimental biofilm with commercially available mouth rinses (CHX & EO) and PS (curcumin), there was significant retention for S.mitis, S.sanguinis and A.viscosus. There was no significant difference observed between PS and CHX treated single species biofilm. Whereas a significant difference was observed between EO treated biofilms and CHX/PS treated biofilms (p⩽ 0.05). CONCLUSION: It can be concluded from the results that curcumin PS and CHX should not be used after meals whereas EO containing mouth rinse can be used to maintain the oral mocroflora.

Association Between Oral Microbiota and Oral Leukoplakia: A Systematic Review.

Literature evidence suggests a significant gap in research exploring the association between the oral microbiota and leukoplakia. So, this review aimed to thoroughly assess the body of research and look at the connection between leukoplakia and the oral microbiome. Databases such as Pubmed/MEDLINE (Medical Literature Analysis and Retrieval System Online), Embase (Excerpta Medica Database), Web of Science, Scopus, CINAHL (Cumulated Index to Nursing and Allied Health Literature), and Cochrane Library were searched using MeSH keywords using a standard data extraction protocol that was designed to ensure comprehensive extraction of relevant information from the selected studies, adhering to the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines. Seven studies were selected that were relevant to this review's objectives. The findings indicate that patients with leukoplakia had a diverse oral microbiota compared to healthy controls. The connection between the oral microbiomes of leukoplakia patients and oral cancer cases was also found, indicating possible microbial profile similarities. By shedding light on particular microbial species and variations in the oral microbial flora of leukoplakia, the studies that were included in this review reveal possible biomarkers and provide a deeper knowledge of the disease mechanism. The considerable overlap between oral microbiomes in leukoplakia cases highlights the need for more research into common microbial indicators and the implications for diagnosis and prognosis.

Applications of artificial intelligence in the field of oral and maxillofacial pathology: a systematic review and meta-analysis.

BACKGROUND: Since AI algorithms can analyze patient data, medical records, and imaging results to suggest treatment plans and predict outcomes, they have the potential to support pathologists and clinicians in the diagnosis and treatment of oral and maxillofacial pathologies, just like every other area of life in which it is being used. The goal of the current study was to examine all of the trends being investigated in the area of oral and maxillofacial pathology where AI has been possibly involved in helping practitioners. METHODS: We started by defining the important terms in our investigation's subject matter. Following that, relevant databases like PubMed, Scopus, and Web of Science were searched using keywords and synonyms for each concept, such as "machine learning," "diagnosis," "treatment planning," "image analysis," "predictive modelling," and "patient monitoring." For more papers and sources, Google Scholar was also used. RESULTS: The majority of the 9 studies that were chosen were on how AI can be utilized to diagnose malignant tumors of the oral cavity. AI was especially helpful in creating prediction models that aided pathologists and clinicians in foreseeing the development of oral and maxillofacial pathology in specific patients. Additionally, predictive models accurately identified patients who have a high risk of developing oral cancer as well as the likelihood of the disease returning after treatment. CONCLUSIONS: In the field of oral and maxillofacial pathology, AI has the potential to enhance diagnostic precision, personalize care, and ultimately improve patient outcomes. The development and application of AI in healthcare, however, necessitates careful consideration of ethical, legal, and regulatory challenges. Additionally, because AI is still a relatively new technology, caution must be taken when applying it to this industry.

Gene sequencing applications to combat oral-cavity related disorders: a systematic review with meta-analysis.

Gene sequencing (GS) has numerous applications in combatting oral-cavity related disorders, including identifying genetic risk factors for diseases, developing targeted therapies, and improving diagnostic methods. It can help identify specific genetic mutations or variations that increase the risk of developing oral-cavity related disorders, such as oral cancer, periodontal disease, and cleft lip and palate. By the means of the following investigation, our primary objective was to assess the impact of GS technique in diagnosing and potentially treating diseases of the oral cavity by the means of a systematic review and meta-analysis. We commenced by defining the terms "gene sequencing," "oral cavity," and "disorders" as the important elements in our investigation's subject. Next, relevant databases like PubMed, Scopus, Embase, Web of Science, and Google Scholar were searched using keywords and synonyms for each concept, such as "genomic sequencing," "DNA sequencing," "oral health," "oral diseases," "dental caries," "periodontal disease," "oral cancer," and "salivary gland disorders." We combined several search terms, such as "gene sequencing AND oral disorders AND periodontal disease" or "oral cancer OR genomic sequencing," to further hone your search results using Boolean operators like "AND" and "OR." The oral cavity analysis obtained by CS in the selected articles revealed that most of the disorders were, in fact, a direct causal event influenced by the oral microbiome. Moreover, each sampled oral cavity evidenced a different microbial community, which predicted the precipitation of benign as well as malignant conditions, though not on a definitive basis. In the last ten years, genomic sequencing had advanced remarkably as majority of our selected studies observed, making it possible to diagnose and treat a variety of oral and maxillofacial disorders, including cancer. It was also used to ascertain a person's genetic make-up as well as to spot numerous genetic abnormalities that can predispose individuals to diseases. Understanding the different sequencing techniques and the resulting genetic anomalies may help with their clinical application and lead to an improvement in illness diagnosis and prognosis as a whole in the field of dentistry.

PEEK surface treatment on surface roughness and bond integrity to composite resin utilizing Er: YAG, Rosebengal activated by PDT, and aluminum trioxide particles.

AIMS: To evaluate the impact of conditioning protocols, aluminum trioxide (Al2O3), Er:YAG laser (EYL), and Rosebengal (RB), on the surface roughness (Ra) and shear bond strength (SBS) of polyetheretherketone (PEEK) attached to composite restorations. METHOD: Eighty PEEK discs in total were produced and then divided into four groups (n = 20). Group1:Sulfuric acid (SA), Group 2: PDT (RB), Group 3: Al2O3, Group 4 EYL, respectively. The Ra of PEEK discs was evaluated using the surface profilometer. After being luted, the discs were attached to composite resin discs. After that, samples were put to SBS testing on a Universal testing apparatus. A stereo microscope was also used to evaluate the type of breakdown. The data were analyzed using Tukey's test and one-way analysis of variance. RESULTS: The SA treated group exhibited the highest Ra. Nevertheless, the RB specimens activated by PDT treatment had the lowest mean Ra score. The group that received the treatment of SA exhibited the highest average score of SBS. In contrast, specimens treated with PDT and activated by RB exhibited the lowest levels of bond fidelity. Cohesive failure emerges as the prevailing kind of fracture within the various groups subjected to testing. CONCLUSION: The utilization of Al2O3, RB activated by PDT, and EYL shows promise as a viable substitute for Sulfuric acid in enhancing the bond integrity of composite cement and surface roughness in PEEK materials.

Ameloglyphics: A Forensic Tool for Human Identification.

Crime rates in our contemporary technological age have been rising at an alarming pace. Newer methods are needed to determine who the perpetrator and victim are in these situations. By comparing a person's recorded information with their own unique characteristics, automated biometric systems may determine who they are. Biometric identifiers like fingerprint and iris scanning are among the most reliable ways. Due to the vulnerability of soft tissues, these procedures cannot be depended on in the event of widespread calamities such as fires or gas leaks. Therefore, improved individual identification necessitates a biometric system based on the hard tissue. Thus, ameloglyphics was created to serve as a key tool in forensic odontology, particularly in the case of huge fatalities caused by natural catastrophes.

Clinical and radiographic peri-implant outcomes with riboflavin loaded Poly-L-glycolic acid nanoparticles incorporated in aloe-vera gel treating peri-implantitis in chronic hyperglycemic patients.

AIM: The objective of the current study was to compare the effectiveness of antimicrobial photodynamic therapy (PDT) versus Poly-L-glycolic acid nanoparticles loaded riboflavin incorporated in aloe vera gel (PGA/RF/AV) on periimplant parameters and bacterial counts in chronic hyperglycemic patients having periimplantitis. METHODS: One hundred and two diabetic patients undergoing mechanical debridement (MD) were equally divided into three groups: Group 1: PGA/RF/AV+ MD, Group 2: PDT + MD, and Group 3: MD alone. Periimplant parameters [Bleeding on probing (BoP), probing depth (PD), plaque index (PI), marginal bone level (MBL)] were recorded in all three groups. Periimplant plaque samples were studied to record the levels of Tannerella forsythia (Tf) and Porphyromonas gingivalis (Pg). The recordings were taken at baseline, 3 months and 6 months post treatment. RESULTS: All three groups showed a reduction in severity of periimplantitis measured in terms of PD, PI, MBL and BoP. A statistically significant reduction in PD, PI and MBL was found in patients in Group 2 whereas participants of Group 1 were found to have a significant decrease in BoP. A statistically significant decline in the numbers of both the bacterial species was seen in Group 2 at the three-month follow-up whereas at the six-month follow-up, a statistically significant reduction was observed in treatment Group 2 in the levels of Tf species only. CONCLUSION: Riboflavin-loaded nanocarrier incorporated in aloe vera gel showed greater clinical efficacy than PDT alone in the treatment of periimplantitis in chronic hyperglycemic individuals.

The Association of Helicobacter pylori in the Oral Cavity With Dental Caries in Patients With and Without Gastric Infection: A Systematic Review.

Helicobacter pylori (H. pylori) organisms are well-recognized pathogens responsible for many GI diseases. Streptococcus mutans-related caries and H. pylori infection share similar risk factors such as early childhood occurrence and low socioeconomic status. Therefore, it is possible for these two bacterial diseases to co-exist in the same environment. The present review evaluates the association of H. pylori with dental caries in patients with and without gastric infection, with the objective of comparing the association of H. pylori with dental caries in patients with and without gastric infection. A computerized literature search was performed in online databases from September 2000 to September 2022 using both electronic and manual searches for scientific databases. The research question was framed following the patient/population, intervention, comparison, and outcomes (PICO) statement. A thorough literature search identified a total of 200 manuscripts. Out of which, 100 were duplicate records and 100 were screened for eligibility, and about 78 articles were excluded, as they were not following PICO and the eligibility criterion. The retrieved 22 articles were sought for retrieval, only 17 were retrieved, and two studies did not fulfill the requirement. A total of 15 studies were recorded as eligible for the present review. There is a close association between the presence of infection of H. pylori in the oral cavity and the increased number of dental caries incidence in patients, even without a gastric infection. This suggests that the oral cavity is another niche for H. Pylori and may be the source of infection, re-infection, and transmission into the stomach.

Role of Extracellular Heat Shock Protein 90 Alpha in the Metastasis of Oral Squamous Cell Carcinoma: A Systematic Review.

Heat shock proteins (HSPs) are expressed in a variety of cancers in human beings and are correlated with differentiation, proliferation, and metastasis. Head and neck squamous cell carcinomas, like other tumors, are exposed to environmental stress, and lack of oxygen and nutrients, and in such situations, hypoxic inducible factor (HIF) initiates the expression of genes causing angiogenesis, invasion, and metastasis. Extracellular heat shock proteins 90 alpha (eHSP90α) are overexpressed in cancers leading to tumor progression and metastasis. Hence, this review will focus on the role of eHSP90α in the metastasis of oral squamous cell carcinomas (OSCC). Different online databases were scoured for relevant articles from October 2000 to October 2022. A total of 342 articles along with duplicates were excluded. The retrieved 45 articles were studied and 39 of them were found to be not eligible as they lacked intervention and their outcome measures did not match with the present review. The final qualitative evaluation included four articles that fulfilled the eligibility criterion. A definitive expression of HSP90 was implicated, as seen in three studies, suggesting its probable role as a prognostic marker for OSCC, but no conclusive evidence was found. The present review suggests that eHSP90α plays a significant role in OSCC. Though a positive association was found between HSP90 expression and its possible correlation with metastasis, affirmative evidence can only be derived with the conduction of many more research studies and their subsequent synthesis of results.

Prevalence of Temporomandibular Disorders in Orthognathic Surgery patients: A systematic review conducted according to PRISMA guidelines and the Cochrane Handbook for Systematic Reviews of Interventions.

BACKGROUND: Orthognathic surgery is done to treat a variety of dentofacial abnormalities, but a wide gap still remains on how it can result in temporomandibular joint dysfunction (TMD). The primary goal of this review was to assess the effects of various orthognathic surgical techniques on the emergence or exacerbation of TMJ dysfunction. METHODS: A comprehensive search was conducted across several databases using Boolean operators and MeSH keywords related to temporomandibular joint disorders (TMDs) and orthognathic surgical interventions, with no limitation on the year of publication. Two independent reviewers screened the identified studies based on predetermined inclusion and exclusion criteria, followed by a risk of bias assessment using a standardised tool. RESULTS: Five articles were considered for inclusion in this review. A greater number of females opted for surgical options than their male cohorts. Three studies were of prospective design, 1 of retrospective and 1 of observational type. Mobility on lateral excursion, tenderness on palpation, arthralgia and popping sounds were the TMD characteristics that showed significant differences. Overall, orthognathic surgical intervention did not show an increase in TMD signs and symptoms as compared to nonsurgical counterparts. CONCLUSION: Though orthognathic surgery reported greater cases of some TMD symptoms and signs as compared to the nonsurgical cohorts in four studies, the conclusive evidence is debatable. Further studies are recommended with a longer follow-up period and greater sample size to determine the impact of orthognathic surgery on TMJ.

Telemedicine in the diagnosis and management of temporomandibular disorders: A systematic review conducted according to PRISMA guidelines and the Cochrane Handbook for Systematic Reviews of Interventions.

BACKGROUND: Telemedicine (T-Med) has always been an important tool in the arsenal of clinicians worldwide. This technique has become increasingly popular in recent years, especially in light of the COVID-19 pandemic, which has made it difficult for some people to access traditional dental care. The current review aimed to analyse the usage of telemedicine in the diagnosis and management of temporomandibular disorders (TMDs) and its impact on general health. METHODS: An extensive search of databases was conducted using keywords such as, "telemedicine," "teledentistry," "TMJ" and "temporomandibular disorders," resulting in a total of 482 papers to be available from which eligible studies were selected. The Risk of Bias in Observational Studies of Exposures (ROBINS-E) tool was used to evaluate methodological quality of included studies. RESULTS: Two studies were selected which fulfilled the eligibility criteria. All assessed studies indicated varying degrees of positive outcomes for patients who were intervened for TMDs using T-Med. CONCLUSION: T-Med shows promising results for the diagnosis and management of TMDs, especially since the advent of the COVID-19 pandemic and thereafter. Long-term clinical trials with larger samples are needed to further ascertain validity in this regard.

Use of final irrigants MTAD, Salvedora Perscia, Malachite green, and Ti-sapphire laser on push-out bond strength of Zirconia post.

AIM: Evaluation of the push-out bond strength (PBS) of zirconia post-bonded to radicular dentin after using different final irrigants (MTAD, Malachite green (MG), Ti-sapphire laser and Salvadora persica (S.persica). MATERIAL AND METHOD: Forty human permanent single-rooted were decoronated above the cement-enamel junction. An experienced endodontist performed all the root canal instrumentation using ProTaper universal rotary files. Canals were irrigated using 5.25% NaOCl solution followed by EDTA as a final sterilant. Obturation with gutta-percha using AH Plus sealer was performed. Post-space preparation was completed using Gates Glidden and specimens were randomly assigned to four groups based on the final disinfectant received (n=10). Group 1: 5.25% NaOCl + MTAD, group 2: 5.25% NaOCl + MG, group 3: 5.25% NaOCl +Ti-sapphire laser, and group 4: 5.25% NaOCl + S. persica. The chemically polymerized resin was used to lute zirconia posts. PBS and failure mode analysis were performed using a universal testing machine and stereomicroscope at 40X magnification. Data were compared between the two groups with 95% CI using one-way analysis of variance (ANOVA) with the Tukey post hoc test. p=0.05. RESULTS: Group4(5.25% NaOCl+ S.persica) specimens demonstrated the maximum (8.94±0.14 MPa) bond strength. Conversely, the apical third of Group 2 (5.25% NaOCl+ MG) (2.87±0.15 MPa) samples revealed the minimum bond strength scores. Intergroup comparison exposed that Group 1 (1.3% NaOCl+ MTAD), Group 3 (5.25% NaOCl+Ti-sapphire laser), and Group 4 (5.25% NaOCl+ S. persica) at all three-thirds unveiled no significant difference in PBS (p<0.05). CONCLUSION: Ti-sapphire laser and Salvedora Persica possess the potential to be used as a final root canal irrigant to improve the push-out bond strength of zirconia post-to-root dentin.

Micro Tensile bond strength and microleakage assessment of total-etch and self-etch adhesive bonded to carious affected dentin disinfected with Chlorhexidine, Curcumin, and Malachite green.

AIMS AND OBJECTIVES: Assessment of micro tensile bond strength (microTBS) and micro-leakage scores of total-etch adhesive (TAE) and self-etch adhesive (SAE) bonded to carious affected dentin (CAD) sterilized using different cavity disinfectant (curcumin photosensitizer (CP) and malachite green (MG) and Chlorhexidine (CHX) in comparison to no disinfection (ND) control group. MATERIALS AND METHODS: One hundred and twenty human molars having International Caries Detection and Assessment System (ICDAS) scores of 4 and 5 were included. Visual inspection, dental explorer hardness testing, and caries detector solution using 5% basic Fuchsin dye solution was applied to dentin to identify the CAD surface. All the specimens were divided into four groups (n = 30) according to the cavity disinfectants used. Group A: 2% CHX, Group B: CP, Group C: MG, and Group D: ND. Each group was further divided into two subgroups (n = 15) based on the adhesion protocol. Groups A1, B1, C1, and D1 were held using TEA, and groups A2, B2, C2, and D2 were adhered using SEA system. The composite material was then built in 2 mm increments and then cured with light. MicroTBS and failure mode assessment using a universal testing machine (UTM) and stereomicroscope at a 40X magnification was performed on 10 samples from each subgroup. The microleakage assessment was performed using a dye penetration test on five samples from each group. ANOVA and Tukey post-hoc tests were used to compare means and standard deviation (SD) of bond strength and microleakage (p < 0.05). RESULTS The maximum microTBS was displayed by A1= CHX and TEA (13.28± 1.01 MPa). The lowest bond scores were demonstrated by C2= MG and SEA (5.98±0.44 MPa). The highest micro-leakage was exhibited by C1= MG and TEA (58.32 ± 2.11 nm). Whereas, the lowest micro-leakage values were displayed by A2= CHX and SEA (24.34± 1.11 nm). CONCLUSION: Chlorohexidiene displayed better bond strength and the lowest microleakage scores with Total-etch adhesive and Self-etch adhesives when used as a cavity disinfectant. Total-etch adhesives performed better in terms of microTBS scores whereas self-etch adhesives displayed superior seal ability within the same disinfectant group.

Radiographical Evaluation of Morphological Alterations of Mandibular Third Molars: A Cone Beam Computed Tomography (CBCT) Study.

Introduction  Morphological changes or variations in the lower third molar can be of concern during the endodontic, orthodontic, or prosthetic intervention. The goal of the present study was to evaluate the morphological alterations in the roots and root canal of a mandibular third molar in Bhopal, Central India, on cone beam computed tomography (CBCT) images. Methodology CBCT scans of 277 mandibular molars, of both genders, between the ages of 18 and 60 years were assessed for the presence of root numbers, the configuration of the canal based on Vertucci's categorization, and a C-shaped canal. Scan results were analyzed for differences in canal configuration between the roots and topographical distribution. A chi-square test was applied to find any significant differences between the teeth at p 0.05. Results Scans analyzed for variations in the third molar had a mean age of 38.64 + 5.71 years. The majority (95.3%) of the molars had two roots, 1.5% had three roots, and 0.4% had five roots. The mesial side of double-rooted teeth predominantly had Type II canal configuration (67.0%), while it was Type I (79.2%) in the distal aspect of the root. C-shaped canals were detected in 21 teeth, and no significant topographical difference was noted in the CBCT images. Conclusion The majority of the current population showed two roots with the same number of canals in the studied tooth. CBCT can be used as a diagnostic aid in identifying the canal numbers and their configuration so as to render appropriate intervention and minimize subsequent failure.

Role of Advanced Diagnostic Aids in the Detection of Potentially Malignant Disorders and Oral Cancer at an Early Stage.

One of the most prevalent malignancies diagnosed today is cancer of the mouth or oral cancer. Compared to systemic malignancies like lung cancer, colon cancer, etc., oral cancer tends to get less attention from the general public. However, these lesions may be lethal if not treated, even if diagnosed early. Early diagnosis improves the prognosis for successful therapy. Delayed diagnosis is hypothesized to be a pivotal contributor to the dismal oral cancer survival rate over five years. The current standard of care for diagnosis and detection is based on clinical evaluation, the histological study of biopsy material, and genetic methods. There have been several advancements in the diagnostic technologies available to detect oral cancer at the initial phase. This study aims to dissect the cutting-edge methods for detecting oral cancer in its earliest stages.

Therapeutic efficacy of adjunctive photodynamic therapy in the treatment of denture stomatitis.

BACKGROUND: The present report assessed the efficacy of curcumin-mediated photodynamic therapy (CUR-mediated PDT) as an adjunct to antifungal gel treatment by evaluating the salivary interleukin-6 (IL-6) and matrix metalloproteinases-8 (MMP-8) levels together with Candida species counts in denture stomatitis (DS) patients. METHODS: In total, 50 DS subjects were randomly categorized into 2 groups: Group-1: subjects who received the antifungal gel treatment and Group-2: participants who received CUR-mediated PDT. The Sabourad Dextrose Agar and CHROMAgar were utilized for evaluating Candida species counts, while the Enzyme-Linked Immunosorbent Assay was employed to estimate the salivary levels of IL-6 and MMP-8. All clinical evaluations were performed at the baseline, 1 month, and 2 months. RESULTS: In total, group-2 subjects showed a significant decrease in Candida albicans (C. albicans) counts on both follow-ups (i.e., 1-month and 2-month) than group-1 participants. C. krusei count also reduced in group-2 subejcts than group-1 participants at the 2nd follow-up as compared to the baseline, nevertheless, a slight increase in C. krusei count was noticed in group-2 subjects at the 2nd follow-up than the 1st follow-up. The salivary IL-6 and MMP-8 levels in both groups reduced significantly at both follow-ups than the baseline. According to the stepwise logistic regression analysis, no statistically significant correlation was observed between Candida species count and other parameters such as age and gender of the patient, duration of DS, and frequency of treatment(s). CONCLUSION: CUR-mediated PDT is an efficaciousness therapeutic modality for alleviating Candida species counts on the surface of denture and the palatal mucosa, as well as improving the salivary IL-6 and MMP-8 levels in DS patients.

Clinical efficacy of 5-aminolevulinic acid-mediated photodynamic therapy versus topical antifungal agent and surgical excision for the treatment of hyperplastic candidiasis.

BACKGROUND: Hyperplastic candidiasis (HC) is a chronic infection of oral mucosa caused by Candida. Owing to its potential for malignant transformation, its intervention requires attention. Conventional surgical resection might lead to irreversible damage and impact the patient's quality of life. Hence, this study aimed to evaluate the clinical efficacy of 5-aminolevulinic acid (5-ALA)-mediated photodynamic therapy (PDT) alone and in combination with topical antifungal therapy (i.e., nystatin [combination therapy]) in comparison with nystatin and surgical resection for the treatment of HC. METHODS: Forty subjects with clinical and histopathological diagnoses of HC were included in the study. Four study groups, with 10 participants each, were formed as follows: Group-I - receiving antifungal agent [nystatin]; Group-II - receiving surgical resection; Group-III - receiving PDT; and Group-IV - receiving 5-ALA-mediated PDT and nystatin [combination therapy]. Salivary and mucosal samples were collected for the quantification of Candida albicans and the treatment responses to different interventions were recorded at week-4, week-6, and week-8 after finishing therapies. RESULTS: At the 3rd follow-up (i.e., at end of the 8th week after the interventions), complete improvement in 3 (30%), 2 (20%), 1 (10%), and 5 (50%) patients in group-I, group-II, group-III, and group-IV, respectively was observed. A statistically significant difference was obtained when the intervention responses were compared at week-4 (p<0.01), week-6 (p<0.01), and week-8 (p<0.0001) follow-ups in group-I, group-II, and group-IV subjects. At the 8-week follow-up regarding the salivary and mucosal samples, the lowest colony-forming units/milliliter score of C. albicans was observed in group-IV subjects. CONCLUSION: The application of 5-ALA-mediated PDT in combination with nystatin gel possesses the potential as a well-tolerated and safe therapeutic modality for the treatment of patients with HC.

A Questionnaire-Based Study to Assess Knowledge and Awareness Regarding Cheiloscopy as a Forensic Odontology Diagnostic Tool Among Dental Professionals.

Background: The lips are covered with grooves and wrinkles, which form a characteristic pattern called a "lip print. The study of lip prints is called cheiloscopy. Searching for lip prints in the crime scene investigation helps in personnel identification and establishment of the true nature of the crime. Objective: This study aimed to assess the knowledge and awareness of cheiloscopy among dental undergraduates, postgraduate students, and general dental practitioners. Materials and methods : This cross-sectional observational, descriptive, survey-based study was conducted among 320 dental professionals, which included undergraduates, graduates, postgraduate dental students, and general dental practitioners aged between 18 and 32 years. A self-administered structured questionnaire written in English and Arabic was distributed to all willing participants. The questionnaire included knowledge and awareness-based questions along with demographic details of the participants. The Chi-square and Fisher's exact tests were applied to find out the association between the characteristics of the study participants and their knowledge and awareness of forensic odontology. A p-value of 0.05 was considered significant for all the statistical tests using IBM Corp. Released 2017. IBM SPSS Statistics for Windows, Version 25.0. Armonk, NY: IBM Corp. Results: A total of 320 dental professionals completed the survey. The majority of participants (55.3%) were males (and 14.4% were females) between the ages of 23 and 27. Most of the participants were general dental practitioners (36.9%), followed by undergraduates (26.3%), graduates (8.8%), and postgraduates (18.1%). Cheiloscopy, the study of lip prints, was known to 36.6% of the participants. Whereas the majority of the participants (63.4%) were not aware of it. Postgraduate (46.7%) students had more knowledge as compared to undergraduates, graduates, and general dental practitioners. About 81.6% of the participants were not aware of the classification of lip prints by Tsuchihashi and Suzuki. Conclusion:Overall, there was a lack of knowledge and awareness of cheiloscopy among all study participants, although they had good knowledge of forensic odontology. Compared to undergraduates and graduates, postgraduate dentistry students showed a greater level of cheiloscopy knowledge and awareness. Comparatively to students, general dentists, however, lacked understanding and awareness of cheiloscopy. This condition, however, can be improved if necessary steps are taken to make forensic odontology a part of the dental curriculum in Saudi Arabia.

Correlation of Body Mass Index to Oral Hygiene and Dental Caries in School Students: An Original Research.

Introduction: The general health of the individual can be calculated using the body mass index (BMI). In our study, we aim to evaluate the association of the BMI to the oral hygiene (OH) and dental caries (DC), in the school pupils. Materials and Methods: We piloted a cross-sectional study with 1000 participants of the ages 5-15 years with mixed dentition. We evaluated the BMI and the Oral Hygeine Index (OHI), DC. We compared the two oral parameters among pupils to the BMI using "ANOVA and Logistic regression analysis" for the identification of the significance and correlation. Results: We observed a significant variation for the different categories of the BMI and the OH, DC. BMI and the OHI, DC both depicted a strong and positive correlation. Conclusions: The nutritional status and the oral health are interrelated. Good oral health has to be promoted for the better general health.
