Brief summary

The purpose of this clinical study is to evaluate how different local anesthesia techniques affect pain and anxiety levels in children undergoing dental treatment. Specifically, the study compares traditional syringe-based anesthesia with a computer-controlled local anesthesia system. The study seeks to answer the following question: Which combination of anesthesia technique is most effective in reducing pain and anxiety in pediatric dental patients? By understanding the impact of these variables, the study aims to help dental professionals choose the most appropriate anesthesia approach to improve the comfort and emotional well-being of children during dental procedures.

Detailed description

This randomized controlled clinical trial will be conducted at the Department of Pediatric Dentistry, Faculty of Dentistry, Dicle University. The study will include 84 voluntary pediatric patients aged between 7 and 10 years who meet the eligibility criteria defined.These patients will be selected among those who present with a clinical need for pulpotomy or pulpectomy proce dures in their primary molar teeth located in either the upper or lower jaws. Prior to any intervention, patients and their legal guardians will be fully informed about the study, and written informed consent will be obtained. The study aims to evaluate and compare the impact of traditional local anesthesia techniques and computer-controlled local anesthetic delivery systems (CCLAD) on children's pain and anxiety levels during dental procedures. In a within-subject crossover design, both traditional (syringe-based) and computer-controlled anesthesia methods will be applied to the same patient but on different sides of the mouth. This design enables objective comparisons and minimizes inter-individual variability. A total of 42 patients will be included in each group, with each child serving as their own control. Local anesthesia will be administered to teeth requiring treatment either on the left or right side, depending on the clinical indication. The primary and secondary outcome measures will include assessments of both physiological and psychological parameters. Pain and anxiety will be measured using a combination of psychometric, physiological, and biochemical evaluation methods. These include: Physiological measurements: heart rate, oxygen saturation (SpO₂) and body temperature. Psychometric scales: Facial Image Scale (FIS) Visual Analog Scale (VAS) Wong-Baker Faces Pain Rating Scale (WBS) Modified Child Dental Anxiety Scale (MCDAS) Children's Fear Survey Schedule-Dental Subscale (CFSS-DS) FLACC Behavioral Pain Scale (Face, Legs, Activity, Cry, Consolability) Data from these assessments will be recorded for both groups and analyzed to determine which anesthesia technique provides the best outcome in terms of minimizing pain and anxiety. Although this is not a patient registry study, quality assurance measures will be applied to ensure data integrity. These include: Regular validation checks for consistency and completeness during data entry. Source data verification against patient records and clinical forms. A standardized data dictionary defining all variables used, including their measurement units and coding schemes where applicable. Implementation of standard operating procedures (SOPs) for participant enrollment, data collection, safety monitoring, and data management. Statistical analyses will be planned according to a predefined protocol, using appropriate tests to evaluate differences between interventions. A sample size calculation has been performed to ensure that 84 patients are sufficient to detect clinically significant differences. A missing data management plan is in place to handle incomplete or inconsistent entries, ensuring statistical robustness and data quality. This study is expected to contribute valuable evidence to the field of pediatric dentistry by identifying the most effective and child-friendly local anesthesia method, thereby improving patient care and treatment experiences.

Interventions

DEVICEDigital Anesthesia with SleeperOne 5

For both maxillary and mandibular teeth, 1.7 mL of Ultracaine D-S Fort carpule (4% articaine with 1:200,000 epinephrine) was administered in two stages (gingival and intraosseous injection) using a computer-controlled intraosseous anesthesia system with a 30-gauge, 9 mm Effitec needle.

DEVICEInfiltration Anesthesia with a Metal Cartridge Syringe

For maxillary teeth, buccal infiltration is performed using a metal carpule syringe and a 30G, 16 mm Effitec needle (Dental Hi Tec, France); after aspiration, Ultracaine D-S Fort is slowly injected over 1 minute.

DEVICEMandibular Block Anesthesia with a Metal Cartridge Syringe

For mandibular teeth, the injection site is dried, and a 27G, 35 mm Effitec needle (Dental Hi Tec, France) is inserted between the pterygomandibular raphe and internal oblique ridge, aligned with contralateral molars. After aspiration, Ultracaine D-S Fort is slowly injected over 1 minute using a traditional metal carpule syringe, following the standard mandibular block technique.

Design outcomes

Primary

MeasureTime frameDescription
Body temperature measurement to assess the patient's anxiety (Before,after and during anesthesia)through study completion, an average of 6 month.Tympanic Temperature Measurement Under stress or anxiety, adrenaline increases heart rate and body temperature. Tympanic thermometers measure core temperature through the tympanic membrane, providing accurate, non-invasive, and rapid readings. This method is effective in ICU settings for both adults and children, offering advantages like minimal infection risk and resistance to environmental changes.
To assess the patient's anxiety level (Before and after anesthesia)through study completion, an average of 6 month.Facial Image Scale (FIS) The Facial Image Scale (FIS) is a projective tool designed to quickly assess pre-procedural anxiety levels in young children, starting from age 3. It consists of five faces, ranging from very happy (score = 1) to very unhappy (score = 5), reflecting increasing levels of fear.
Pulse rate measurement to assess patient's dental anxiety (Before,after and during anesthesia)through study completion, an average of 6 month.Measurement will be made with a pulse oximeter.The measurement will be performed using a pulse oximeter attached to the patient's fingertip.

To assess the patient's pain level (Before and after anesthesia)through study completion, an average of 6 month.Wong-Baker Faces Pain Rating Scale 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.
To assess the patient's pain level (During anesthesia)through study completion, an average of 6 month.The Visual Analog Scale (VAS) is a unidimensional tool used to measure pain intensity on a continuous spectrum, ranging from no pain to worst imaginable pain. It consists of a 10 cm line with descriptive anchors at both ends. In our study, VAS will be applied as a 10 cm horizontal line marked at 1 cm intervals to quantify pain levels.
To assess the patient's anxiety level (Before anesthesia )through study completion, an average of 6 month.The CFSS-DS is a validated psychometric scale developed in 1982 to assess dental anxiety in children. It includes items scored from 1 (not afraid) to 5 (very afraid). Total scores indicate anxiety levels as follows: \<38: No anxiety 38-45: Moderate dental anxiety \>45: Severe dental anxiety
