The objective of this study is to restore, through the occlusal plane, the aesthetics and functionality of a piece treated endodontically in the posterior sector through an endo-crown. The following case is a 27-year-old male patient with no relevant medical history who attended the SERODU dental clinic. The radiographic examination revealed the endodontic canals, which were protected by a cavity base and provisional filling. The intraoral examination revealed that tooth number 46 lost the distal wall and part of the palatine, so it was decided to carry out the rehabilitation with an endo-crown, as it has a good hermetic seal at the coronal level, it prevents possible re-contamination of the treatment endodontic resulting in a conservative and feasible alternative. 

The lack of harmony in a patient's smile affects their self-esteem and behavior with their environment. Ecuador has been considered an endemic zone of fluorosis, triggering aesthetic and functional dental alterations. Fluorosis appears as opaque spots that follow a horizontal pattern in its early phase and brown spots and loss of structure in an advanced stage. In this article we present the case of a young patient, diagnosed with dental fluorosis grade three of Thylstup-Fejerskov (TF) index, treated with 40% hydrogen peroxide bleaching, followed by 35% peroxide carbamide home whitening for 30 minutes daily, during 7 days. The combination of whitening procedures was ideal to mimic the mottling characteristic of dental fluorosis, thus improving the aesthetics of the patient and guaranteeing the success of the present case. The use of a conservative treatment was effective to restore denta...
