Abstract
Seventy single-rooted mandibular premolar teeth were selected, cleaned and stored in normal saline solution. They were sectioned at the level of the cementoenamel junction and the rootcanal preparation was done as per the manufacturer’s recommendations. The teeth were then divided into five groups, two of which were used as positive and negative control groups. The other three groups were obturated with matched taper single cone technique, cold lateral condensation technique and thermoplasticized gutta-percha injection technique (obtura-II) respectively. The teeth were then subjected to a dye penetration technique using high vacuum and left in the dye solution for 24 hrs. They were then cleaned and subjected to a technique for clearing the roots. Subsequently the dye penetration at the apex was measured in all the three groups using a binocular stereomicroscope and analysed using a Leica application suite. The results were tabulated and statistically analysed. CONCLUSION: Matched taper single cone obturation technique was evaluated for the apical seal in comparison with the cold lateral condensation technique and thermoplasticized gutta-percha injection technique (obtura-II) of obturation and the following conclusions were made. 1. The thermoplasticized gutta-percha injection technique of obturation, obtura-II (Group-3) showed the least amount of apical percolation of dye and was better than other two techniques in the apical sealing ability. 2. There was statistically significant difference between all the three groups (p<0.05). 3. Matched-taper single-cone technique of obturation (Group-1) showed the highest amount of apical percolation of the dye. 4. The cold lateral condensation method of obturation (Group-2) was also efficient in terms of apical sealing ability though it could not match Group-3, ( p<0.05). The matched taper single cone technique needs to be further studied and evaluated with regards to the limitations of this technique.
