DUAL SHAPER Chameleon

PREPARE FOR SUCCESS WITH THE DUAL SHAPER CHAMELEON FILES

A case study by Dr Georgios Tsompanides

"A male patient was referred to Dr Georgios Tsompanides for the management of acute spontaneous pain localized to the upper right first maxillary molar (tooth 16)."

1. Diagnosis

Following thorough clinical and radiographic examination the initial diagnosis was symptomatic apical periodontitis /initiated endodontic treatment and nonsurgical endodontic treatment 16 was recommended.

2. Shaping the canals

The tooth was anesthetized and the root canal treatment was performed with the aid of the dental operating microscope under rubber dam isolation The initial access cavity was slightly modified to facilitate the identification and scouting of previously missed MB 2 canal. The DENCO DENTAL DUAL SHAPER Chameleon series rotary files were used for root canal preparation with the Step Down technique.

Cervical preflaring was done with the SX opener file to minimize coronal interferences. The canals were negotiated with ISO #10 K files and working length measurement was determined for each canal with an apex locator device.

Subsequently glide path was established with the 16 / 0.02 – 0.06 file. The MB1, MB2 and DB canals were enlarged to size 25 / 0. 04 ; whereas the palatal canal was enlarged to size 25 / 0.06

3. Irrigation protocol

During root canal preparation, irrigation was performed using copious amount of 3% sodium hypochlorite solution followed by 17% EDTA solution. Sodium hypochlorite solution was used for the final rinsing of the root canal system coupled with ultrasonic agitation.

4. Intracanal medication

Calcium hydroxide was placed as an intracanal medicament with a lentulo spiral and the access cavity was sealed with a temporary filling material.

5. Obturation

At the next appointment after 2 weeks, the patient was asymptomatic. The irrigation protocol was repeated, the canals were dried with absorbent points and obturated with gutta-percha and a resin-based sealer using the continuous wave of condensation technique.

The pulp chamber floor was sealed with a flowable resin composite and a temporary filling material until final crown restoration by the referring dentist.

6. Recall

The patient was asymptomatic during the subsequent follow-up period and a full coverage crown restoration was recommended to the referring dentist.

Dr Tsompanide's opinion on DUAL SHAPER Chameleon files

"The DUAL SHAPER Chameleon Series files, due to the heat-activation and the laser coating, feature improved fatigue resistance, higher flexibility along with excellent cutting efficiency. Root canal preparation is controllable, predictable and safe. They are highly recommended for all simple and complex clinical cases."
