Pain Perception With a Comfort-ın Jet Injection and Conventional Dental Injection
Condition: Pain; Local Infiltration; Anesthesia; Fear; Anxiety; Needle Phobia
Study type: Interventional

Summary: 
      The investigators aimed to compare the effectiveness of the Comfort-in system, which is a jet
      injection type, and infiltrative anesthesia with a traditional injector, and to measure the
      effect of children's anxiety on the severity of pain.
    

Detailed description: 
      Among the children between the ages of 4 and 10 who were admitted to clinic between
      2018-2020, whose clinical and radiographic examinations were completed; Patients with
      deciduous teeth that needed the same dental treatment (filling or amputation) with
      symmetrical local anesthesia application and positive (3) or definitely positive (4)
      according to the Frankl Behavior Evaluation Scale were included in the study. In study with a
      split-mouth design, infiltration anesthesia was applied with a conventional dental injector
      to one of the symmetrical teeth requiring the same treatment, while the Comfort-in jet
      injection system was applied to the other by the same physician. Patients were randomized
      into two grups according to the injection technique.

      Group1: Needle-free injection system(Comofrt-In) 2:Dental injection method. The pain
      intensity was assessed during anesthesia(Pain 1), during treatment(Pain 2), at the end of the
      treatment(Pain 3) and on the postoperative 1st day (Pain 4)by the specially 7 colors (white,
      yellow, green, blue, magenta, red, black) using the Wong-Baker facial expressions and pain
      grading scale.Anxiety levels were recorded using the Modified Children's Dental Anxiety Scale
      face version.

      The data were analyzed by IBM SPSS Statistics 19, the significance level was taken as p
      <0.05.The datas were analyzed with a three-way variance method in repeated.
    

Intervention name(s): Needle-free injection
Intervention type(s): Behavioral
Intervention description(s): This study was performed among children aged 4-10 years who required dental treatment and were treated at the Department of Pedodontics, Faculty of Dentistry, Gaziosmanpasa University. A total of 120 patients were evaluated in accordance with the exclusion criteria and 94 children (39 girls and 55 boys) were included in this study. Children who needed dental treatment were randomly divided into two groups. All dental injections were administered by the same operator (MB), a pediatric dentist with two years of experience in using the Comfort-In system.
In both groups, the children were asked to rate their pain intensity by choosing the closest statement on the colorful Wong-Baker Pain Scale at four time points: immediately after injection (Pain 1), during treatment (Pain 2), at the end of the treatment (Pain 3) and postoperative first day.Anxiety levels were recorded using the Modified Children's Dental Anxiety Scale face version
