Introduction
Renowned Japanese dentist Dr. Hidetaka Ishizaki recently provided detailed feedback on two clinical cases where he used Rogin’s SF-shape rotary file for root canal treatments. His insights emphasize the effectiveness and precision of the SF-shape rotary file in endodontic procedures. Here, we delve into the specifics of these cases to highlight the capabilities of this advanced dental tool.
Case 1: Maxillary Left Second Molar
Patient Profile
– Age/Gender: 40-year-old female
– Symptoms: Biting pain on maxillary left second molar, tender to percussion, no spontaneous pain.
– Diagnosis: Large caries with exposed pulp
Procedure
- Preoperative Steps: Removal of caries and temporary buildup with flowable resin.
- Canal Preparation:
– Instruments Used: TORNA SF-shape rotary files
– Steps:
– Enlargement of root canal orifices with the orifice opener of the SF-shape rotary files.
– Working length measurement followed by canal preparation up to 25/.04 with the SF-shape rotary files.
– Irrigation: 2.5% NaClO solution.
- Filling and Restoration:
– Filling: Size 25/.04 Gutta percha and CSBS.
– Restoration: Tooth was built up with a fiber core and restored with a metal crown.
Case 2: Mandibular Left Second Molar
Patient Profile
– Age/Gender: 27-year-old male
– Symptoms: Spontaneous pain at left lower molar region, unable to sleep due to pain, responsive to percussion, positive to electrical pulp test.
– Diagnosis: Deep caries at the distal aspect, vital pulp not exposed initially.
Procedure
- Initial Treatment: Indirect pulp capping with MTA putty.
– Outcome: No improvement in symptoms, leading to a decision for pulpectomy.
- Canal Preparation:
– Instruments Used: TORNA SF-shape rotary files
– Steps:
– Access opening revealed necrotic coronal pulp.
– Preparation of thin and curved mesio-buccal and mesio-lingual root canals, and oval distal root canal.
– Used SF-shape rotary files 16, 20/.04, and 25/.04 for distal root canal preparation.
– Measurement and Patency: Apex locator used for working length measurement. Preparation confirmed apical patency and maintenance of original root canal morphology.
– Irrigation: 2.5% NaClO solution with each file change.
- Filling:
– Mesio-buccal and Mesio-lingual Canals: Filled with 20/.04 Gutta percha.
– Distal Canal: Filled with 25/.04 Gutta percha and CSBC as a single cone.
Conclusion
Dr. Hidetaka Ishizaki’s feedback on using the SF-shape rotary file underscores its efficiency in root canal preparation and its ability to maintain the original canal morphology. These cases illustrate the reliability and precision of the SF-shape rotary file in managing complex endodontic treatments. The advanced design of the SF-shape rotary file not only facilitates smooth and efficient canal preparation but also ensures patient comfort and successful outcomes.
By integrating the SF-shape rotary file into clinical practice, dental professionals can enhance the quality of endodontic treatments and achieve superior results, as demonstrated in these cases by Dr. Hidetaka Ishizaki.
