Controlled modification of types of oxidants (chloranil vs. DDQ) has led to the isolation of 18π-aromatic porphyrinoid 7 (upon chloranil oxidation) while DDQ oxidation has led to 18 e σ-aromatic porphyrinoids 8 and 9.

The objective of this study was to evaluate the impact of different levels of caries experience on the OHRQoL of pre-school children and their families in Odisha, assessed using Odia version of Early Childhood Oral Health Impact Scale (Od-ECOHIS).
Methodology: A cross-sectional survey was carried out on a sample of 369 pre-school children using Od-ECOHIS.
