About this study
Official title: Evaluation of the Efficacy of Computerized Intraosseous Local Anesthesia System in Children With Molar Incisor Hypomineralization
The goal of this clinical trial is to compare in effectiveness of intraosseous anesthesia and inferior alveolar block anesthesia in children with molar incisor hypomineralization (MIH). The main question it aims to answer are:
- Is intraosseous anesthesia is more effective in pain control when restoring teeth with MIH?
Read the detailed description
The anxiety experienced by pediatric patients is one of the biggest problems that dentists encounter in practice and is closely related to their current oral health. Studies have shown that dental anxiety depends on many factors, but the pain that is thought to occur during the procedure is one of the most important reasons for the formation of dental anxiety. Painful dental procedures cause anxiety, and anxiety prolongs the duration and increases the severity of the pain felt. For this reason, coping with dentist anxiety at an early age and practices that will enable painless dental treatment in pediatric patients should be emphasized. Behavioral guidance techniques and pain management are used to minimize the pain felt during dental treatment.
Various strategies, devices or techniques have been developed to reduce or eliminate pain occurring during local anesthesia injection. Intraosseous injection is an anesthesia with a high success rate. Anesthesia begins in a short time following the injection, it does not cause numbness in the tongue-lips-cheek, there is almost no injection pain, and less anesthetic solution is used compared to traditional nerve block techniques.
Situations that cause dental anxiety in pediatric patients include children with hypersensitive teeth. Molar incisor hypomineralization (MIH) is a qualitative developmental enamel defect affecting at least one permanent molar. The color of these defects can vary from white to yellow and brown, and especially in severe cases, enamel destruction may occur after application. MIH; dental hypersensitivity is among the most complicated cases that require management of various clinical difficulties in pediatric dentistry, such as failure to provide adequate analgesia/anesthesia, increased risk of carious lesion formation, increased dental anxiety, and increased aesthetic anxiety.
MIH continues to be a subject that continues to be researched in pediatric dentistry. Pediatric dentists encounter difficulties in providing adequate depth of anesthesia in restorative treatments, especially in MIH accompanied by hypersensitivity. This thesis study aims to examine the effect of intraosseous anesthesia on procedural pain in patients with MIH.
As a result of the literature review, the following hypothesis was put forward: There is no significant difference in terms of pain perception between intraosseous anesthesia and traditional metal syringe anesthesia in children with MIH.

What is being measured
The primary outcome is the main question the study is designed to answer.
Wong-Baker FACES Pain Rating Scale
Patient-reported pain. The scale contains a series of six faces ranging from a happy face at 0 to indicate "no hurt" to a crying face at 10 to indicate "hurts worst."
Measured: To be measured 2 times on the day of treatment: 1. After local anesthesia application 2. After restoration
Secondary outcomes (4)
Frankl behaviour rating scale
Behaviour assessment. The Frankl scale is an ordinal scale with 4 ratings used to describe a child's behavior from definitely negative (1), negative (2), positive (3), and definitely positive (4).
Measured: To be measured 3 times on the day of treatment: 1. Before local anesthesia 2. During local anesthesia 3. During whole treatment
Pulse rate
Pulse rate
Measured: To be measured 3 times on the day of treatment: 1. Before local anesthesia 2. After local anesthesia 3. After restoration
Blood pressure
Blood pressure
Measured: To be measured 3 times on the day of treatment: 1. Before local anesthesia 2. After local anesthesia 3. After restoration
MCDAS(f) Turkish version
Dental anxiety. Scores on the MCDAS(f) scale may range from 8 to 40, with scores below 19 indicating absence of state anxiety, scores higher than 19 indicating the pres- ence of state anxiety and scores higher than 31, in- dicating severe phobic disorder.
Measured: To be measured 2 times on the day of treatment: 1. In the waiting room before treatment 2. After treatment

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 11 Aug 2025; AzTrials last refreshed its copy on 8 Nov 2026.
