Evaluation of Different Anesthesias in Children With Molar Incisor Hypomineralization

In children with molar-incisor hypomineralization (MIH), insufficient depth of anesthesia can lead to increased anxiety and behavior management problems, which may negatively affect the quality of restorations. This situation has increased the need for modern techniques and devices to minimize pain during local anesthesia. The aim of this study was to compare the effects of the SleeperOne computer-controlled local anesthesia system and the conventional local anesthesia technique on pain and anxiety in children with MIH. The null hypothesis of the study stated that there would be no statistically significant difference between the effects of the two local anesthesia methods on pain and anxiety in children with MIH.

About this study

The study was conducted using a split-mouth design with 28 patients and 56 teeth who met the inclusion criteria and were recruited from the Department of Pediatric Dentistry, Faculty of Dentistry, Tokat Gaziosmanpaşa University. The patients included in the study were randomly assigned to two groups:

  • Control group: Anesthesia administered using the conventional injection technique.
  • Study group: Intraosseous anesthesia administered with the computer-controlled anesthesia device (SleeperOne).

Teeth affected by MIH were classified according to the Molar-Incisor Hypomineralization Treatment Need Index (MIH-TNI). Those in category 2 were evaluated as "Without hypersensitivity," while those in category 4 were assessed as "With hypersensitivity" Prior to the study, all participants completed the Children's Fear Survey Schedule-Dental Subscale (CFSS-DS). Pulse rate, oxygen saturation (SpO₂), and salivary cortisol levels were measured before local anesthesia, after anesthesia, and after treatment. In addition, the Wong-Baker FACES Pain Rating Scale (WBS), Visual Analogue Scale (VAS), and Face, Legs, Activity, Cry, Consolability Scale (FLACC) were used. The data were analyzed statistically.

Treatment and study plan

Computer-controlled anesthesia device (SleeperOne)

Device

Intraosseous anesthesia administered with the computer-controlled anesthesia device (SleeperOne)

Conventional injection technique

Procedure

Anesthesia administered using the conventional injection technique

Primary outcomes

  1. Evaluation of the effect of different anesthesia on pain in teeth with MIH

    Time frame: 6 month

    VAS (Visual Analog Scale), WBS (Wong-Baker Facial Rating Scale for Pain) and FLACC (Face, Leg, Activity, Crying, Consolability Behavioral Pain Rating Scale) scales were used for pain assessment. In the VAS, patients were asked to select the number expressing the level of pain from a linear scale with numerical values between 0-10 (0 no pain, 10 excruciating pain). On the WBS scale, they were asked to choose one of six faces, with the happy face at 0 symbolizing "no pain" and the crying face at 5 symbolizing "the most pain". Both numerical (VAS) and visual (WBS) assessments were made. According to the scores obtained on the FLACC scale: 0 points indicated that the patient was relaxed and peaceful, 1 to 3 points indicated mild discomfort, 4 to 6 points indicated moderate pain and 7 to 10 points indicated severe pain.

  2. Evaluation of the effect of different anesthesia on anxiety in teeth with MIH

    Time frame: 6 month

    The Child Fear Rating Scale-Dental Subscale (CFSS-DS), a numerical scale, was used to assess anxiety in patients. According to the answers given in the CFSS-DS; a score between 15 and 75 is obtained. According to the score; it was accepted that children aged 15-38 years did not have dental anxiety, while children with a score of 38 and above were considered to have dental anxiety.

    Pulse rate, oxygen saturation and salivary cortisol measurements were used in an anxiety assessment.
