Gutta Percha Points;
Gavin gutta percha points are a specialized endodontic material that plays a vital role in dental applications. The use of this material in root canal treatment is crucial for:
- Preventing infections,
- Maintaining the tooth’s health,
- And ensuring its durability.
In the filling of root canals, despite the use of various core materials with gutta percha, it remains the most commonly used material. Gutta percha is the trans-isomer of polyisoprene (rubber). It is harder, more brittle, and less elastic than natural rubber.
It exists in two crystalline forms:
- α (alpha),
- and β (beta) form.
The material in the unheated β phase is incompressible and solid. When heat is applied, the material changes to the α phase, becoming flexible, soft, and sticky. It exhibits fluid properties when pressure is applied. However, when the material hardens, shrinkage occurs. Gutta percha in the α form melts when heat is applied above 65⁰C. When heated gutta percha is slowly cooled, it will recrystallize in the α phase. Routine cooling results in recrystallization in the β phase. Although the mechanical properties of both forms are the same, α phase gutta percha is more stable and shows less shrinkage when heated and cooled for thermoplastic gutta percha filling techniques. Therefore, α phase gutta percha is widely used in these techniques today.
Unlike rubber, gutta percha cannot be compressed or made fluid at room temperature. Gutta percha can be brought to a fluid state with the help of heat or solvents, making it better able to adapt to the root canal wall. Gutta percha oxidizes and becomes brittle when exposed to air, so it should be stored in the refrigerator.
Advantages of Gavin Gutta Percha;
- It has plastic properties, can be softened and shaped with heat.
- It is easy to manipulate.
- Shows minimal toxicity.
- Is radiopaque.
- Can be easily removed from the canal with heat or solvents.
- Gutta percha does not stain the tooth, cause discoloration, or undergo dimensional changes.
- Gutta percha does not have adhesion properties to dentin.
- It must be used with a canal sealer.
Composition of Gutta Percha;
It consists of:
- 20% Gutta-Percha,
- 65% Zinc Oxide,
- 10% Radiopaque material, and
- 5% Plasticizers.
Iodoform, calcium hydroxide, chlorhexidine, and tetracycline have been added to gutta percha to impart antimicrobial properties. However, the clinical effectiveness of this has not been demonstrated.
Gutta percha is biologically compatible. In studies comparing it with root canal sealers, it has shown the lowest toxicity rate. It has demonstrated equivalent biological compatibility with Resilon.
Types of Gutta Percha Cones;
- Traditional cones have both a finer tip and a wider body than standard cones.
- Standardized cones are designed to have the same width and taper angle as endodontic instruments.
For example, a #40 cone corresponds to a #40 canal file.
In recent years, manufacturers have produced various taper angles of gutta percha cones compatible with the dimensions of rotary instruments.
Gutta percha cannot be sterilized with heat, so it is usually treated with sodium hypochlorite as a practical method.
A 1-minute soak in a 5% NaOCl solution is sufficient.
However, before use, it must be washed with ethyl alcohol to remove crystallized NaOCl.
