Mandibular Block or Maxillary Infiltration: Does it Influence Children’s Opposition to a Subsequent Dental Visit?

Local anesthesia by mandibular block or maxillary infiltration is commonly administered to children receiving dental treatment of primary molars. Discomfort, when presenting, most often involves the lower lip. The purpose of this study was to investigate whether children would be more opposed to attending a dental treatment following anesthesia by mandibular block than by maxillary infiltration. Methods: Each of 102 children in two age groups: 3 to 5 years, and 6 to 9 years, received the two types of local anesthesia at dental appointments one week apart. Their opposition to attending a subsequent appointment was assessed by parent report. Results: More adverse reactions were observed during and following anesthesia with mandibular block than with maxillary infiltration. Few of the children in either age group expressed opposition to attend a dental visit after receiving mandibular block or maxillary infiltration in the previous visit. Conclusions: Though more adverse reactions were observed in children following mandibular block than maxillary infiltration, this did not result in increased opposition to attend a subsequent dental appointment.
