Using post is one of the reinforced methods in tooth restoration after endodontic reatment. That’s the reason we operate the topic “Study of clinical features, X-ray and evaluations result of crown’s restoration in patients with large-caries molars at Cantho Medical – Pharmacy University Hospital in 2017- 2018”. Objectives 1. To surveys of clinical and X-ray features in patients have large-caries molars which were endodontically treated, before and after restoration reinforce with posts. 2. To evaluate results of large-caries molars’ restoration with fiberglass and metal posts at Cantho University Hospital after 3 months, 6 months, 9 months treatment. Materials and methods Controlled clinical trials group of 80 large-caries molars which were restored with metal posts and fiberglass posts. Patients were followed 3-6-9 months after treatment. Results In 29 maxilarry molars, 51 mandibular molars 60% still have 3 surfaces, 40% have 4 surfaces; roots which were set the posts 16.3% curve, 83.7% straight. After filling, 85% fulfil the required of aesthetics, 100% tight fitting, X ray 95% were tight-fitting, 66.3% fulfil post length, 91,3% good in pivot axial. The outcomes was in unchanged after 3-month follow-up. Good restoration in 90% metal post cases and 97.5% fiberglass-posts after 6-month treatment. Good restoration in 89.7% metal posts cases, and 97.3% of fiberglass-posts after 9-month follow-up. Conclusions The stability of teeth and restorations reinforce with fiberglass posts or metal posts has no statistical significance.
