RESUMEN
Background: Low protein diets have been linked to decreased bone strength in humans. Arginine and lysine can help improve the healing process and stimulate growth factors. Aim: To evaluate if dietary arginine and lysine combination aids in reducing the time frame for osseo-integration process and bone formation in animal models. Materials and Methods: Controls (Group I) and Experimental (Group II) consisted of twelve New Zealand rabbits. Animals in the experimental group were fed a conventional pellet food, water, and the amino acids L-Lysine and L-Arginine (Biovea, USA), whereas those in the control group were offered a standard diet. In both groups of animals, titanium implants measuring 2.5mm* 6mm were implanted in each tibial osteotomy. At the end of two weeks, four weeks, and eight weeks, the animals were euthanized. The tibial bone was removed and preserved in 1% formalin. The samples were analysed histologically for presence or absence of Necrosis, presence or absence of clot formation, Vascularization, Fibroblast, Osteoblasts and Osteoid Bone growth. Results: Histological outcomes on vascularization, fibroblasts, osteoblasts, osteoid bone growth inferred no significant variation between the control and experimental groups after 8 weeks (P>.05). Conclusion: Vascularity, clot organisation, osteoblasts, fibroblasts, and osteoid bone production in the protein fed experimental group animals were better in initial stages of healing when compared to control groups.
RESUMEN
Recurrent Aphthous ulcers are the most common oral lesions among dental patients. The ulcers, which usually occur on the nonkeratinized oral mucosa, can cause considerable pain and may interfere with eating, speaking, and swallowing. Therefore, it is of interest to report data on the management of recurrent aphthous ulcer using corticosteroids, local anesthetics and nutritional supplements. Case sheets of 76 patients who underwent treatment for recurrent aphthous ulcer between June 2019 and March 2020 at the Saveetha Dental College, India were used in this analysis. Data was analyzed using Chi square test at a P value < 0.05 that is statistically significant. Results show that topical anaesthetics in population (49%) were more effective that corticosteroids. Thus, topical anaesthetics are recommended for recurrent aphthous ulcer.
RESUMEN
Oral Submucous Fibrosis (OSMF) is characterized by Juxta-epithelial inflammation with oedema, fibroblasts, neutrophil and eosinophil inflammatory infiltrate. Therefore, it is of interest to gain insights from an awareness survey on ORAL SUBMUCOUS FIBROSIS (OSMF). The sample size was 100 patients who had participated in this survey in Tamilnadu, India where 93% of the subjects used tobacco products. 81% of the patients were not aware of the malignancy caused by OSMF. A significant number of males use more tobacco than females (p value = 0.006 (<0.05) in the sample dataset. Thus, there is a need to create awareness on OSMF among the general population to combat the associated diseases.
