Precautions taken during endodontic therapy, post cementation, and final restoration are more likely to be responsible for the success of endodontic treatment rather than a specific type of post. Clinical relevance The type of post is not related to the success of the endodontic treatment. The tested posts presented similar endodontic healing.

Orofacial appearance is increasingly recognized as an important dental patient-reported outcome making instrument development and refinement efforts to measure the outcome better necessary. The aim of this study was to derive a one-item version of the Orofacial Esthetic Scale (OES). OES data were collected from a consecutive sample of a total of 2113 adult English- or Spanish-speaking dental patients from HealthPartners dental clinic in Minnesota. Participants with missing data were excluded and analysis were performed using data from 2012 participants. Orofacial appearance was assessed with the English and the Spanish language version of the OES. Linear regression analysis was performed, with the OES item 8 ("Overall, how do you feel about the appearance of your face, your mouth, and your teeth?")as the predictor variable and the OES summary score as the criterion variable, to calculate the adjusted coefficients of determination (R ). The value of adjusted R was 0.83, indicating that the OES item 8 score explained about 83% of the variance of the OES summary score. The difference in R scores between the two language groups was negligible. The OES item 8 can be used for the one-item OES (OES-1). It is a psychometrically sound instrument
