Analysis of microleakage of temporary restorative materials in primary teeth.

Aim: The aim of this study was to compare the coronal microleakage of restorative materials used between sessions of endodontic treatment in primary teeth.

Materials And Methods: Forty healthy primary canines were chosen and randomly allocated to four groups: Group 1 - Cimpat Branco ® (n = 10), Group 2 - Bioplic ® (n = 10), Group 3 - Maxxion R ® glass ionomer cement (n = 10), and Group 4 (control) - Z350 ® composite resin (n = 10). Class V cavities were created and fillings carried out following the manufacturer's instructions.
