Background: The complexity of root canal morphology has fascinated the imaginations of many. Several techniques have been tried in the past to view the three-dimensional anatomy of the pulp canal system with varied success. It has been hypothesized in the present study that a combination of decalcifying agent and clearing agent can be used to prepare transparent tooth model. Aims: The aim of the present study was to access the efficacy of two decalcifying agent (formic acid and nitric acid) and two clearing agents (methyl salicylate and eugenol) to prepare transparent tooth model. Materials and Methods: The study material included 80 freshly extracted teeth both maxillary and mandibular. After decalcifying and clearing of the specimen, they were graded for transparency and haziness criteria. Results: The results of the present study indicated that methyl salicylate when used as a clearing agent showed better transparency, lower level of haziness and good root canal morphology. On the other hand samples cleared by eugenol showed good root canal morphology but lesser transparency and higher degree of haziness and yellowing of samples, more so when used in combination with nitric acid. Conclusion: It was concluded by the present study that combination of nitric acid when used with methyl salicylate proved to be the best combination for the preparation of the transparent tooth model.
