ENDODONTIC TREATMENT IN DECIDUOUS TEETH WITH CTZ PASTE

Abstract

Maintaining the integrity of primary teeth until natural exfoliation is crucial for the development of the permanent occlusion, with endodontic treatment being an essential procedure to achieve this goal. This study aimed, through a narrative literature review conducted in national and international databases between 2000 and 2025, to evaluate the clinical efficacy of the main obturating materials used in this context: CTZ paste, calcium hydroxide, and Guedes-Pinto paste. The results, based on the analysis of clinical studies and systematic reviews, indicated varying success rates, with CTZ paste showing the best outcomes (85% to 95%), followed by Guedes-Pinto paste (80% to 85%) and calcium hydroxide (70% to 80%). Success was determined mainly by the absence of clinical signs such as pain or pathological mobility and the absence of radiographic changes, such as internal resorption or fistulas. In conclusion, although CTZ paste proved superior in the analyzed literature, all materials demonstrated clinical effectiveness. However, a definitive confirmation of the superiority of one material over the others depends on conducting further longitudinal and controlled studies that directly compare these formulations.
