One hundred thirty-four children between the ages of 3 to 12 who visited the department of Paediatric Dentistry, Chosun University Dental Hospital, for dental treatment requiring local anaesthesia were selected for this study, regardless of previous dental experience, and randomly divided into the following 2 groups: alternative and conventional.
Gender, race, and ethnic restrictions were not applied, and emergency cases were not selected for this study. Patients who needed a mandibular block were included in both groups.
Patients were excluded from the study if they had behavioural management problems.
This study protocol was approved by the Institutional Review Board (IRB) of Chosun University Dental Hospital, Gwangju, Korea.
The written informed consents were obtained from all patients prior to study and they were informed about the aim of the study. All parents were informed about the treatment and associated procedures.

Reframing techniques, i.e., those using euphemistic phrases, e.g., “injecting the cotton roll only, not on your teeth”, were used to describe the injection to all the children.
No sedative or other pharmacological supports, such as nitrous oxide, were used in this study. Positive reinforcements and reassurance were given to the subjects throughout the insertion process.
