A lip and cheek retractor made of soft, flexible material such as OptraGate® is handy for establishing full access to the oral cavity. The lip and cheek retractor is comfortable to wear and adapts to the natural movements of the patient. Because of its elasticity, OptraGate retracts the soft tissues gently and assists patients in keeping their mouth open. In particular, patients experiencing severe tension of the masticatory musculature as a result of e.g. bruxism may feel that the lip and cheek retractor alleviates their pain and helps them to relax. The lip and cheek retractor is therefore a valuable aid for both patient and clinician.
Postoperative sensitivities can have any of a number of causes: They often occur if the dentin tubules and collagen network are exposed because they are not properly covered with adhesive. In these cases, external stimuli may result in movement of fluid within the dentin tubules and cause hypersensitivity. This phenomenon is known as microleakage and can be avoided. One way of preventing it is to use an adhesive (e.g. Adhese Universal) that comprises hydrophilic solvents and methacrylate monomers that can wet and infiltrate the dentin tubules in moist and dry conditions. In addition, the acidic compounds in the dentin precipitate as insoluble calcium salts, facilitating the mechanical blocking and sealing of the dentin tubules. This integrated "desensitizing effect" prevents the fluid flow within the dentin tubules and reduces the risk of microleakage and postoperative sensitivities. Using the adhesive in conjunction with the self-etch technique may be an additional measure to prevent hypersensitivity.
Consequences include weakened bond strength, post-operative sensitivity, compromised color stability, an increased release of chemicals into your body, and a higher risk of fracture in undercured restorations.
Regularly check the curing light tip for any chips or cured resin, and follow proper maintenance procedures. Using a barrier/sleeve over the light guide can contribute to optimal performance.
Holding the light tip directly over your restoration and perpendicular ensures that the light travels in a straight line, maximizing its effectiveness in curing your restoration and preserving anatomical features.
