Aim: The purpose of this study was to determine whether patients with class 2 skeletal malocclusion in a private dental hospital had skeletal discrepancies.Materials and methods: This was a descriptive, retrospective study, and the dental information archiving software was used to collect all the data from the patients who attended the dental clinics at Saveetha Dental College, SIMATS, Chennai, India (DIAS). March 2020 through March 2021 saw the collection of patient records. We gathered and tabulated the data. The gathered data underwent additional processing, was entered into Microsoft Excel, and then went through statistical analysis using IBM SPSS statistics analyzer v.23.0.Results: The current study used a total sample size of 88950 patients. Skeletal class 2 malocclusion was seen in 0.01 percent of cases overall. The data in this study was examined for the occurrence of different skeletal inconsistencies. Results were satisfactory and showed that there were skeletal differences. A gender bias was evident, with 50.4 percent of the sample population being female. Mandibular deficit was the most frequent skeletal discrepancy, and class 2 div 1 dental malocclusion was most frequently detected.Conclusion: Mandibular deficit was shown to be the most common skeletal discrepancy within the constraints of the current investigation, and a substantial correlation between the skeletal discrepancies and the gender of the study group was found.

Introduction: Terminalia Arjuna (TA) has been used in the field of ayurvedic and unani medicine for quite some time now. It has been shown to possess several medicinal properties. Literature has highlighted the osteoinductive properties of TA and has been extensively been used for its fracture healing and bone forming potential. This would have a positive impact in the field of periodontics and orthodontics, which require bone grafts to maintain ideal periodontal conditions. Aim: To synthesise TA-mediated Hydroxyapatite Nanoparticles (TA-HApNPs) and subject it to morphological assessment and evaluate its cytotoxic and antioxidant properties. Materials and Methods: This in-vitro study was done under a laboratory setting within the city of Chennai, Tamil Nadu, India, extending for a period of one month from April 2022 to May 2022. A 1 g of TA plant bark was mixed with 100 mL distilled water and heated to derive the plant extract. A 20 mL of distilled water was mixed with 0.502 g of Hydroxyapatite (HAp). An 80 mL of TA extract was mixed with 20 mL of HAp solution. The mixture was placed in a magnetic stirrer and was subjected to an Ultraviolet Visible (UV-Vis) double beam spectrophotometer. The solution was dried and was subjected to Transmission Electron Microscope (TEM) analysis for morphological characterisation, 2,2-Diphenylpicrylhydrazyl (DPPH) assay for the assessment of antioxidant properties and brine shrimp lethality test to evaluate its cytotoxic properties. The results were obtained electronically, tabulated in a spreadsheet and were subjected to descriptive statistics using Microsoft excel 2019 Management Services Organisation (MSO) (Version 2202; Build 16.0.14931.20118). Results: UV-Spectroscopy revealed a sharp peak at 375 nm wavelength suggesting Nanoparticle (NPs) formation. Spherical shaped NPs with size ranging from 5-25 nm were seen under the TEM. At concentration of 48 µL also TA-HApNPs elicited good cytotoxicity as seven out of 10 brine shrimps were alive at the end of 24 hours. Good antioxidant properties at 50 µL concentration with a DPPH assay reading of 1.044 was noted. Conclusion: The TA-HApNPs can be synthesised using simple and routinely used laboratory armamentarium in the size range of 5-25nm. TA-HApNPs have minimal cytotoxic effect and a good antioxidant activity

The term IRIS is almost solely used in human immunodeficiency virus seropositive patients who initiated anti-retroviral therapy (ART), the term paradoxical reaction is generally used to describe a clinical worsening of tuberculosis disease after the initiation of antituberculosis treatment. Distinguishing this paradoxical reaction (PR) from disease progression or treatment failure is an important issue in CNS tuberculosis management. Thus, one must keep a watch for neurological deterioration in a child with Central nervous system tuberculosis (CNS TB). We are presenting a case of a non-Human immunodeficiency virus (HIV) child who developed TB-IRIS while on anti-tubercular drugs, who subsequently responded to steroids along with continuation of antitubercular treatment (ATT).
