Aim of the study: This study was conducted to demonstrate which treatment option was preferable for the endodontists between single sitting versus multiple sitting Root Canal treatment for posterior teeth. Materials and methods: A questionnaire survey was conducted in 30 Endodontists to understand their knowledge and selection of cases where single or multiple sitting RCTs are preferred over a time period of a year. Results: Single visit therapy is mostly practiced by practically 65.0% of all endodontists interviewed in cases of vital pulp, but when the biological status of the pulp progresses to being necrotic, then very few still choose this treatment type. Anterior teeth were mostly done in a single sitting as compared to posterior teeth RCTs. Conclusion: The practitioner should not routinely apply one technique to all situations, but rather evaluate the circumstances peculiar to each particular case and then choose the technique that best fits those circumstances.
