How can pain and anxiety during periodontal instrumentation be reduced?

Several complementary strategies can reduce pain and anxiety during periodontal instrumentation.

Regarding anesthesia delivery, needleless jet anesthesia systems produce significantly lower pain scores (VAS and VRS both p < 0.05) and less post-operative soreness compared to conventional syringe injection, and patients report lower anxiety and greater comfort with this approach ^[1].

Addressing anxiety directly is important because dental anxiety is a consistent predictor of expected pain, pain during treatment, and post-treatment pain across all types of dental procedures and treatment stages, so identifying anxious patients early is a critical step in pain control for all patients, not just those with high anxiety ^[2].

Non-pharmacological interventions - including muscle relaxation, guided imagery, biofeedback, hypnosis, acupuncture, distraction techniques, and desensitization - can modify the patient's experience with minimal or negligible side effects ^[3]. Meta-analytic data confirm that non-pharmacological interventions produce a significant reduction in anxiety levels (SMD = -0.32; 95% CI -0.57 to -0.07; p = 0.01) ^[4].

Pharmacological options such as nitrous oxide, oral sedation, or conscious intravenous sedation are also available, though they carry potential side effects, risks, contraindications, and increased cost ^[3]. Evidence supports that combining pharmacological and non-pharmacological methods yields superior outcomes compared to either approach alone ^[5]. For patients with mild to moderate anxiety, behavioural interventions including effective communication and relaxation techniques are particularly appropriate, while pharmacological sedation is better suited to moderate-to-severe dental fear ^[6].
