DNAsensing inflammasomes, such as AIM2 and IFI16, are key mediators in the secretion of IL-1 and IL-18 and facilitate pyroptosis in periodontitis. Andrographolide and resveratrol are phytocompounds known for their anti-inflammatory effects, though their precise mechanisms of action remain uncertain. This study aimed to elucidate the molecular interactions of andrographolide and resveratrol with AIM2 and IFI16 inflammasomes using a computational approach. &lt;strong&gt;Methods:&lt;/strong&gt; Ten phytocompounds were selected and analyzed via molecular docking. Protein-ligand docking was conducted with AutoDock 4.2.6. Binding affinities and hydrogen bond interactions were assessed. Andrographolide and resveratrol complexes with AIM2 and IFI16 were further subjected to 100 ns molecular dynamics simulations using GROMACS software to assess complex stability. &lt;strong&gt;Results: &lt;/strong&gt;Both andrographolide and resveratrol complexes demonstrated stability throughout the simulations, with adequate inter-hydrogen bonding. Molecular Mechanics Poisson-Boltzmann Surface Area (MMPBSA) analysis revealed that AIM2-andrographolide (-112.100 ± 18.106 kJ/mol) and IFI16-andrographolide (-50.047 ± 27.076 kJ/mol) complexes exhibited higher binding energies compared to AIM2-resveratrol (-15.328 ± 2.539 kJ/mol) and IFI16-resveratrol (-12.534 ± 20.184 kJ/mol) complexes. &lt;strong&gt;Conclusion:&lt;/strong&gt; Molecular docking and dynamics analyses indicate that andrographolide demonstrates a stronger binding affinity to AIM2 and IFI16 inflammasomes compared to resveratrol. This suggests andrographolide as a promising host modulatory candidate for the therapeutic management of periodontitis.&lt;/p&gt;

Diagnosis of chronic periodontitis was established depending on dental history, clinical examinations (periodontal indices). All participants were examined by the same dentist. They were classified into three groups: Group 1 (control negative): (15) participants with normal serum vitamin D3 level and with pocket depth ≤3 mm, good oral health and normal periodontal tissues and no previous history of periodontal diseases. Group 2 (control positive): (15) participants with normal serum vitamin D3 level and periodontitis with pocket depth ≥5 mm, they received placebo medication orally, Group3(treatment): (15) participants with vitamin D3 deficiency (below 30 IU), and periodontitis with pocket depth ≥5 mm, they received oral Vitamin D3 fast acting liquid soft gel capsule 2000 IU /day for 3 months. 3 blood samples were taken from each participant at 0,45,90 days, for research examinations. CYP27A1, CYP27B1 serum levels was measured for each sample in three groups by ELISA kit. &lt;strong&gt;Result:&lt;/strong&gt; there was a highly significant reduction in CYP27A1 serum level in the treatment group at the ninety days of the study while there was no significant elevation CYP27B1 serum level in all groups during 45,90 days of the study. &lt;strong&gt;Conclusion:&lt;/strong&gt; The present study suggested that the 1,25(OH)2D has effects on serum levels of both Cytochromes CYP27A1 and CYP27B1 and this was associated with periodontitis.&lt;/p&gt;

RT - PCR was used to examine the expression of the iNOS gene in activated macrophages. The Statistical analysis for multiple comparisons was evaluated by one way ANOVA followed by the Dunnett’s test when significant differences were detected. The data were considered to be statistically significant at &lt;em&gt;p&lt;/em&gt; &amp;lt; 0.001, &lt;em&gt;p&lt;/em&gt; &amp;lt; 0.01 and &lt;em&gt;p&lt;/em&gt; &amp;lt; 0.05.&lt;strong&gt; Results: &lt;/strong&gt;LPS stimulated RAW macrophages strongly up regulated the iNOS gene expression levels. The iNOS levels were significantly suppressed in the presence of different concentrations of tamarind extract, compared to LPS treatment alone. The tamarind extract also exhibited dose – dependent decrease in the production of NO. The IC&lt;sub&gt;50 &lt;/sub&gt;was found to be 35.69 μg/ml. LPS stimulated group showed 89.61 ± 0.47 % of NO. &lt;strong&gt;Conclusion:&lt;/strong&gt; Nitric oxide production is found to be more in conditions such as periodontitis, oral squamous cell carcinoma and many other diseases. This study could prove the ability of tamarind fruit pulp extract to inhibit the production of nitric oxide and the iNOS gene expression. Hence, &lt;em&gt;Tamarind indica&lt;/em&gt; Linn pulp extract may be used as a good anti-inflammatory agent in periodontitis as well as in conditions associated with over production of nitric oxide in different cancers such as oral squamous cell carcinoma.&lt;/p&gt;

However, a normal PRF membrane has rapid degradability (1-2 weeks). Myristica fragrans (nutmeg) has been found to have antiprotease property. It was hypothesized if this property helps in inhibiting degradation of PRF. &lt;strong&gt;Aim:&lt;/strong&gt; To assess whether nutmeg has any effect in inhibitingdegradability of PRF membrane and to compare the degradability of PRF at different concentrations (200mg, 100mg, 50mg) of ethanolic and crude extracts of nutmeg. &lt;strong&gt;Materials and Methodology:&lt;/strong&gt; PRF was procured from 30 ml blood from 5 different donors were cut to equal sizes into 35 pieces. They were measured at baseline and dropped in 7 sets of ependorphs containing PBS, PBS containing 200 mg, 100mg and 50 mg crude extract of nutmeg, PBS containing 200 mg, 100mg and 50 mg ethanolic extract of nutmeg. After 1 week the PRF were retrieved and measured. The percentage of remaining PRF was calculated and data analysed. &lt;strong&gt;Result:&lt;/strong&gt; It was found that there was a difference in percentages of remaining PRF between all the groups when compared to the control group, out of which, crude extract of nutmeg 200 mg group alone had a significantly lesser % of remaining PRF than the control. All ethanolic extract groups had a significantly greater % of remaining PRF when compared to that of the control. &lt;strong&gt;Conclusion:&lt;/strong&gt; Nutmeg is effective in inhibiting the degradation of PRF membrane.&lt;/p&gt;</style></abstract><issue><style face="normal" font="default" size="100%">4</style></issue><work-type><style face="normal" font="default" size="100%">Original Article</style></work-type><section><style face="normal" font="default" size="100%">672</style></section><auth-address><style face="normal" font="default" size="100%">&lt;p style=&quot;text-align: justify;&quot;&gt;&lt;strong&gt;Darshanaa Arunachalam&lt;sup&gt;1&lt;/sup&gt;, Sheeja Varghese&lt;sup&gt;2*&lt;/sup&gt;, Lakshmi Thangavelu &lt;/strong&gt;&lt;/p&gt;
