TITLE: Influence of finishing procedures on color and translucency of composite resins

Case report CASE 1: This case presented A 29year-old male who complained of acute nocturnal pain at the right maxillary central incisor level. His medical history was not contributory with the exception of an episode of renal colic. Intraoral examination revealed a small lesion at the cervical-distal angle of 1.1, and a change in underlying coloration to a pinkish tone. Periapical radiogaphy revealed a rounded radiolucid cervical lesion restricted to the cementoenamel junction level. Therefore the CRR was diagnosed as Heithersay Class 2. In this case a conservative treatment that included endodontic treatment, realization of periosteal flap surgery and restoration with resin composite was performed. CASE 2: A 22-year-old woman complained of pain at the right maxillary central incisor level. The patient’s medical history only indicated a nephrolithiasis episode. In the intraoral inspection of 1.1, a well-defined small lesion was found at cervical area of the palatal surface. The underlying area of the lesion showed pink coloration. Periapical radiography detected an irregular radiolucid lesion that extended from the cementoenamel junction towards the middle third of the root. To confirm the true extent of the lesion, we used cone-beam computerized tomography (CBCT), which showed severe root resorption corresponding with a Heithersay class 4. In view of the extensive nature of the lesion, the treatment option selected included tooth extraction and placement of an immediate implant with a temporary crown.
