MATERIALS AND METHODS: A total of 60 subjects were selected for this study. 40 subjects presented with periodontitis, which included 20 snuff users (SP) and 20 nonsnuff users (NS). 20 periodontally healthy patients formed the controls (healthy control: HC). The clinical parameters recorded were gingival index (GI), plaque index, calculus index, bleeding on probing (BOP), probing depth (PD), recession (RC), and clinical attachment level (CAL). The IL-1 β and IL-8 levels were assessed through enzyme-linked immunosorbent assay (Quantikine(®)). Analysis of variance (ANOVA), post-hoc Tukey's, Kruskal-Walli's ANOVA and Mann-Whitney test was used for comparison among groups and P > 0.05 was considered statistically significant.

RESULTS: No significant difference was seen in levels of IL-1 β and IL-8 between SP and NS groups (P = 0.16, 0.97). However, both the periodontitis groups (SP and NS) had increased IL-β levels when compared to HC group (P = 0.01, 0.001). The snuff users showed significant increase in GI, BOP, RC, and CAL when compared with NS (P = 0.002, 0.001, 0.012, 0.002) whereas NS group had significant increase in PD (P = 0.003).

METHODOLOGY: Latest telemedicine guidelines of the South Asia Region of the WHO were accessed using the official government websites of the countries. The guidelines that were not in the English language were translated into English using Google Translate. The guidelines were analyzed and presented under the following subheadings: (1) Definitions, Purpose, and Tools of Telemedicine; (2) Clinical Aspects of Telemedicine; and (3) Operational and Technical Aspects of Telemedicine.

RESULTS: Investigating the telemedicine guidelines in the SEAR of the WHO revealed that only 5 out of 11 countries, that is, India, Bangladesh, Thailand, Indonesia and Nepal, have guidelines specifically for telemedicine. Besides Thailand, the other four countries either published (India, Nepal, and Bangladesh) or updated (Indonesia) their telemedicine guidelines after the onset of the COVID-19 pandemic. Guidelines from India and Bangladesh are detailed and robust compared with those from Nepal, Indonesia, and Thailand.
