Is it essentially required to Provide Crowns to Endodontically Treated Maxillary Premolars? A Clinical Study Determining Success Ratio between the Direct Restorations and Full Coverage Prosthesis in Maxillary Premolars

Aim: To evaluate the success outcome of direct restorations as compared to metal ceramic crowns in endodontically treated maxillary first premolars. Methods: This descriptive study was carried out at Akhtar Saeed Dental Hospital, Bahria Town, Lahore from 1st July 2016 to 31st December 2016. A total number of 88 patients were selected. Sixty seven patients were male and 21 were females. All the patients had got their maxillary first premolar (right or left) root filled. All the teeth were sound and having maximum bulk of enamel in the buccal aspect. The patients were categorized randomly into three groups. Group 1 received full coverage metal ceramic crown. Group 2 got the silver amalgam restoration and group 3 received the resin composite fillings. The evaluation of all three groups were performed at six months interval and finally evaluated at the end of 12th month. All evaluations were by the modified Ryge criteria. Results: The null hypothesis was accepted. The obtained result was not declared to be significant at p<0.05. Conclusion: Indirect restoration may be a good option for the endodontically treated maxillary first premolars regarding the longevity of tooth and being socioeconomically beneficial for the patients.
