Modified OXIS Classification of Interproximal Contacts of Primary Canines and Its Prevalence in Six-to-Nine-Year-Olds in the Delhi National Capital Region: A Cross-Sectional Study.

Introduction: The modified OXIS (O - open contact, X - point contact, I - straight contact, S - curved contact) classification provides a useful framework for assessing interproximal contacts in primary canines and predicting caries risk. The study aimed to assess the incidence of modified OXIS classification of canine interproximal contacts in six-to-nine-year-old children from the Delhi National Capital Region (NCR) population.

Methods: A cross-sectional study was conducted to assess the interproximal contact areas between primary canine and first molar among six-to-nine-year-old children (n=400) according to the modified OXIS classification using the die stone study model.

Impact of Cryotreated and Warm Sodium Hypochlorite on Postoperative Pain in Teeth With Symptomatic Irreversible Pulpitis: A Randomized Controlled Trial.

Introduction: The purpose of this study was to evaluate effect of cryotreated and warm sodium hypochlorite (NaOCl) on postoperative pain in patients with symptomatic irreversible pulpitis and symptomatic apical periodontitis.

Methods: Sixty-six individuals with preoperative pain scores of ≥54 mm on the Heft Parker Visual Analogue Pain Scale (HP-VAS) diagnosed with symptomatic irreversible pulpitis and symptomatic apical periodontitis as per the American Association of Endodontists guidelines in mandibular molars were included. The preparation of the access and the root canals was instrumented and irrigated in accordance with a standard protocol.
