Comparative evaluation of efficacy of external vibrating device and counterstimulation on child's dental anxiety and pain perception during local anesthetic administration: a clinical trial.

Background: This study aimed to evaluate the efficacy of external vibrating devices and counterstimulation on a child's dental anxiety, apprehension, and pain perception during local anesthetic administration.

Methods: This was a prospective, randomized, parallel-arm, single-blinded interventional, clinical trial. One hundred children aged 4-11 years, requiring pulp therapy or extraction under local anesthesia (LA), were recruited and allocated equally into two groups (1:1) based on the interventions used: Group BD (n = 50) received vibration using a Buzzy® device {MMJ Labs, Atlanta, GE, USA} as a behavior guidance technique; Group CS (n = 50) received counterstimulation for the same technique.

Comparison of a New Auto-controlled Injection System with Traditional Syringe for Mandibular Infiltrations in Children: A Randomized Clinical Trial.

Background: Pain in the dental operatory can have a profound effect on the behavior of children.

Aim: The aim of this study is to evaluate the pain perception while administering local infiltration, in children undergoing dental extractions, using a new auto-controlled injection system.

Materials And Methods: Children in the age range of 6-10 years with teeth indicated for extraction were recruited and allocated to either Group I, computer-controlled injection system (auto system with special cartridge and compatible disposable 30-gauge, 10 mm needles), or Group II, traditional system (30-gauge, 10 mm needle and disposable traditional syringe).

Recurrent mandibular supplemental premolars: a case report with 5 year follow up and review of literature.

A 12-year-old girl reported for a routine dental checkup. Radiographic survey disclosed the presence of two developing structures resembling premolars one on either side of the mandible in premolar region, which were of supplemental type and surgical removal of supernumerary premolars facilitated eruption of the left second premolar. On six months follow-up, there was radiographic evidence of another supernumerary premolar in the left side of mandible that is left in situ, patient is on regular follow-up.
