RESUMO

Background Early screening and diagnosis of oral squamous cell carcinoma (OSCC) has always been a major challenge for pathologists. Artificial intelligence (AI)-assisted screening tools can serve as an adjunct for the objective interpretation of Papanicolaou (PAP)-stained oral smears. Aim This study aimed to develop a handy and sensitive computer-assisted AI tool based on color-intensity textural features to be applied to cytologic images for screening and diagnosis of OSCC. Methodology The study included two groups consisting of 80 OSCC subjects and 80 control groups. PAP-stained smears were collected from both groups. The smears were analyzed in Matlab software computed data and color intensity-based textural features such as entropy, contrast, energy, homogeneity, and correlation, were quantitatively extracted. Results In this study, a statistically significant difference was noted for entropy, energy, correlation, contrast, and homogeneity. It was found that entropy and contrast were found to be higher with a decrease in homogeneity, correlation, and energy in OSCC when compared to the control group. Receiver operating characteristic curve analysis was done and accuracy, sensitivity, and specificity were found to be 88%, 91%, and 81%, respectively. Conclusion The gray-level co-occurrence matrix (GLCM) color intensity-based textural features play a significant role in differentiating dysplastic and normal cells in the diagnosis of OSCC. Computer-aided textural analysis has the potential to aid in the early detection of oral cancer, which can lead to improved clinical outcomes.

RESUMO

Traumatic oral ulcers are one of the most commonly encountered oral ulcers. Their healing may be delayed due to factors like the presence of opportunistic infectious microbes in the oral cavity, secondary trauma from sharp edges of teeth, and the systemic condition of the patient. AIM: To compare the efficacy of a newly developed neem extract containing herbal ointments (propolis and Hemidesmus indicus) in enhancing the wound contraction of traumatic oral ulcers and to determine the relationship between oxidative stress and oral ulcers. METHOD: Ulcers were inflicted by trauma in the mouths of experimental rabbits using a 5 mm punch biopsy device. Forty-eight animals were randomly put into six groups (n = 12). Group 1 was the control group that did not receive any intervention; Group 2 had a systemic treatment of Hemidesmus indicus extract; Group 3 received a topical application of propolis; Group 4 had a topical application of a neem extract-based herbal ointment; Group 5 was administered a combination of Hemidesmus indicus and propolis; and Group 6 had a combination of a neem-based herbal ointment and Hemidesmus indicus. Oxidative stress levels were calculated by measuring superoxide dismutases and malondialdehyde levels in the blood on days 0, one, seven, and 14. Wound contraction scores of ulcers were also assessed on days seven and 14. RESULTS: Significantly higher wound contraction scores were seen in groups treated with herbal ointment in comparison to groups treated without herbal ointment. Oxidative stress levels increased in all groups after the infliction of ulcers (day one) and then declined as the ulcers healed, reaching near-normal levels on day 14. Groups containing Hemidesmus indicus showed a significant reduction in oxidative stress in comparison to groups without Hemidesmus indicus. A p-value of <0.05 was considered significant. CONCLUSION: A combined formulation of herbal ointment and Hemidesmus indicus proved to be the most efficacious in enhancing wound contraction of oral ulcers along with significantly reducing oxidative stress in experimental rabbits.

RESUMO

Most of the currently used medications for the treatment of oral ulcers focus primarily on providing symptomatic relief and preventing secondary infections. Not much attention has been paid in the past on agents that can promote healing of these lesions. In the current study, we have tested and compared the efficacy of such wound healing promoting agents i.e. Propolis (product obtained from Bees) and a newly developed herbal ointment (containing extracts of Azadirachta indica (Neem), Linum usitatissimum L.(Linseed) oil, and resin of Shorea robusta) in experimental rabbits. METHODOLOGY: Traumatic oral ulcers were inflicted in experimental rabbits (New Zealand white) with the help of a punch biopsy instrument. The animals were then divided into three groups each group consisted of 12 animals (n = 12), Group I was the untreated control group and Group II was topically treated with nonalcohol extract of propolis and Group III was treated with newly developed herbal ointment. Histological healing scores of the ulcers were evaluated on day 7 and day 14. Data were statistically analyzed using descriptive and inferential statistic methods. RESULTS: In Group III treated with newly developed herbal ointment, significantly higher healing scores, in comparison to the untreated control group (Group I) and propolis (Group II) was observed on day 7 and 14. Improved healing scores in prapolis-treated group were observed than the untreated control group. However, the difference was not statistically significant on both day 7 and day 14. CONCLUSION: With the newly developed herbal ointment, superior healing of traumatic oral ulcers was observed.
