How do you reduce postoperative sensitivity after composite restoration?
Postoperative sensitivity linked to microleakage and can be reduced by pre-conditioning the tooth with air abrasion of the cavity 8 or low level laser treatment of the tooth before restoration on the axial wall of Class V cavities.
Does composite cause sensitivity?
Post-operative sensitivity occurs in up to 50% of composite restorations, per some studies, and is especially prevalent in posterior teeth and Class II restorations, but not limited to them. Post-operative sensitivity could have various causes.
What is postoperative sensitivity?
Postoperative hypersensitivity can be defined as pain in a tooth associated with mastication or with sensitivity to hot, cold, and sweet stimuli that occurs 1 week or more after restoration.
How long are composite fillings sensitive?
The range of sensitivity is different for every patient. In a normal-small to moderate size filling, sensitivity to cold temperatures usually subsides within a couple of weeks. If the temperature sensitivity persists longer than that, it may be normal for you, but should slowly shows signs of improvement.
Why are newly restored teeth sensitive for a period of time?
After the completion of a filling, teeth may be hot, cold, or pressure sensitive, which is completely normal and known as pulpitis. Anytime a tooth undergoes the trauma of being drilled and restored, the nerve can become agitated and produce sensitivity that can last for days to weeks.
How can shrinkage of polymerization be reduced?
The only known methods to reduce shrinkage are to reduce the number of methacrylates or utilize a new polymerization chemistry. The silorane-based restoratives (Filtek Silorane, 3M) are an example of novel chemistry in a commercial composite resin.
Why is my composite filling sensitive?
The type of filling your dentist used can also cause sensitivity or discomfort in the tooth. For example, sensitivity is common when a composite resin material is used in the filling. Sensitivity may be a result of the filling shrinking slightly and creating a gap beneath it.
Are teeth with fillings more sensitive?
Tooth sensitivity: A tooth that has just had a filling placed will be more sensitive to hot foods and cold foods, air temperature, and the pressure of biting. This type of tooth pain after filling a cavity should resolve within a few weeks. If not, contact your dentist.
What is dentine hypersensitivity?
Dentine hypersensitivity has been defined as pain arising from exposed dentine, typically in response to chemical, thermal, tactile or osmotic stimuli that cannot be explained as arising from any other form of dental defect or disease [8].
What is sensitivity teeth?
Sensitive teeth are typically the result of worn tooth enamel or exposed tooth roots. Sometimes, however, tooth discomfort is caused by other factors, such as a cavity, a cracked or chipped tooth, a worn filling, or gum disease.
What is C factor in composite restoration?
The cavity configuration or C-factor is defined as the ratio of the bonded to the unbonded surface area. 17. During light-induced polymerization of resin composite, the shrinkage forces in high C-factor cavities cannot be relieved by resin flow, resulting in the debonding of one or more walls.
How to reduce post-operative sensitivity after composite resin?
Use of oxalate desensitizer [21] or 5% Glutaraldehyde [10] and 35% HEMA 10 as a desensitizer agent in deeper cavities helps to reduce post-operative sensitivity. Apply desensitizers twice for a minute each in deep cavities; this helps to decrease POS.
Is it normal to have sensitivity after posterior composite?
Post Operative sensitivity can be both a normal and abnormal sequela of placing a posterior composite. I make sure my patients are expecting some temperature sensitivity, and even tell them to be cautious the first time the have a cold drink after the anesthetic wears off.
How long does Pos last after composite resin restoration?
At-least five to twenty six percent patients report POS immediately after composite resin restoration1. In the authors’ observation, sensitivity typically lasts’ for a period of few days to months and finally settling down to normalcy and in very extreme cases there is pulp involvement leading to endodontic therapy.
What causes failure of the post op Composite?
Posterior Composite: Post Op Sensitivity. Placing too large an increment and using a material with higher shrinkage stress can cause failure of the hybrid zone and post op sensitivity. So if you are experiencing more sensitivity than you would like go back and step by step review your technique.
