Increased flouride use has made it difficult to detect fissure caries using explorers and x-rays. A large percentage of suspect fissures have decay present.
No Stick Surface of fissure in enamel looks relatively healthy, and the explorer does not detect lesion. But you’re suspiscious because of the decalcification and subsurface staining.
No X-Ray Evidence Radiographs do not detect all occlusal lesions. Enamel thickness can be deceptive.
You’re still suspicious. Decay Present A cross section of the same tooth confirms your suspicion. It clearly shows the lesion deep in the enamel and the dentin.
Fissurotomy Instruments are essential when removing decay in deep lesions because they preserve the healthy dentin. This reduces post-operative sensitivity and avoids unnecessary root canal procedures.
A Clinical Scenario: Wait or Explore and Restore
The occlusal fissure of this molar looks suspicious for a carious lesion because of subsurface staining and decalcification; but the explorer does not ‘stick’, indicating a lesion, and there is no x-ray evidence of such. However, radiographs do not detect all occlusal lesions. Enamel thickness can be deceptive.
You’re still suspicious. A cross section of the same tooth would confirm your suspicion. It clearly shows the lesion deep in the enamel.
Solution- Fissurtomy is ideally designed for the ultraconservative pit/fissure exploration of adult molars, primary teeth & adult premolars, enameloplasty and improved sealant retention.
1 Tip of bur is smaller and more conservative than 1/4 round
2 Fine carbide tip will not strip quickly like thin diamonds
3 Virtually pain free to the DEJ... in most cases no anesthesia is needed
4 Ideal cavity preparation form for a flowable composite
5 Cleaner, more controlled and less costly than air abrasion
6 Multiple bur tip sizes to suit adult and deciduous teeth
Our burs are engineered to deliver superior consistency, strength and cutting rate with minimal vibration for maximized performance and procedural comfort for you and your patient.
Carefully designed blade structure, rake angle, flute depth and spiral angulation combined with our specially formulated tungsten carbide results in the powerful cutting performance of our burs. SS White burs are engineered to deliver the most efficient cutting rate & performance for the most popular procedures.
SS White® is ISO 13485, EN46001 and CE Mark Certified which means an SS White® bur is manufactured to the highest quality standards. SS White® reflects the importance of manufacturing to the highest standard of quality in its Quality Policy
SS White® adheres to strict tolerances for concentricity of shank and head profiles during manufacturing. The result is a well-balanced carbide that: delivers minimal vibration when subjected to the rotational speeds of the dental hand-piece and maximizes performance and procedural comfort for you and your patient.
SS White® brings over 160 years of continuous improvement in the design and manufacturing of dental instruments. In 1947, SS White® introduced the first carbide bur to the dental profession and we continue to innovate operative, finishing and specialty carbide burs to serve the needs of modern dentistry.
SS White® solid carbide burs are made with high quality fine-grain tungsten carbide, which produces a blade that is sharper and wears longer compared to less expensive coarse grain tungsten carbide. Blades made of fine grain tungsten carbide, retain shape even as they wear. Less expensive, large particle tungsten carbide dulls quickly as the large particles break from the blade or cutting edge
