The most frequently used drugs in
dentistry are local anaesthetics, either plain or in combination with a vasoconstrictor. Their side effects are likely to be the cause of many of the emergencies encountered by dentists. Certain precautions should always be taken when they are used. Below are listed the toxic manifestations provided by
dentist Sutherland of each agent, but it should be remembered that some of the effects of the base will be masked by the vasoconstrictor.
In practice it would seem that the commonest side effects seen are those due to adrenaline or nor-adrenaline. If the warning signs associate: with these toxic effects are not appreciated and administration ceased, there I is a high risk that the patient will collapse.
Adverse and toxic effects are determined by:
- Concentration and volume of solution.
- Rate of injection.
- Toxicity of agent.
- Presence or absence of vasoconstrictors.
- Physical status of the patient and his or her current drug therapy.
The major cause of systemic reactions is a high blood level of local anaesthetic base or vasoconstrictor. The aim must be to use the smallest volume of lowest concentration to achieve satisfactory anaesthesia. more info at
