It is a great pleasure and an honor to extend a warm invitation to attend the 23rd ISP Post Graduate Convention to be held at Biswa Bangla Convention Centre, Kolkata on 04/04/2025 and 05/04/2025. The theme of the convention is “Perio-kitab and beyond”. The era of digitalization sometimes make people forget about the books. Hence we are trying to recapitulate by going through the Perio-kitab. With less than a year to go before the national event of the ISP – The 23rd ISP Post Graduate Convention , the entire organizing committee is working harder than ever to bring you an exciting and unforgettable convention. The convention is being organized to promote and facilitate the dissemination of information related to the best clinical practices of Periodontics. This Convention will provide a wonderful forum for you to refresh your knowledge base and explore the latest research, innovations and latest treatment modalities in Periodontics. We are leaving no stone unturned in ensuring that your visit to Kolkata is memorable one. Looking forward to welcome you all to Kolkata.
