Not applicable Interventional Istanbul University · NCT07547371

This study tests whether inhaled lavender and orange aromatherapy and a computer-controlled local anesthesia system reduce anxiety and pain for 6–12-year-olds having a lower primary molar removed.

What this trial studies

This randomized, controlled, parallel-group study will enroll 132 children aged 6–12 at Istanbul University Faculty of Dentistry who need extraction of a lower primary molar. Participants are randomly assigned to one of four groups: conventional infiltration anesthesia, computer-controlled intraosseous anesthesia (SleeperOne 5), aromatherapy plus conventional anesthesia, or aromatherapy plus computer-controlled anesthesia. Aromatherapy uses an ultrasonic diffuser delivering a lavender and sweet orange essential oil blend by inhalation before anesthesia, and the study measures anxiety, reported pain, cooperation, and comfort during the extraction. The protocol includes computer-generated randomization, parental informed consent, and standardized timing and procedures to compare these approaches.

Who should consider this trial

Good fit: Children aged 6–12 who need extraction of a lower primary molar, are generally healthy, and whose behavior is rated Frankl 2–4 with parental consent fit the study.

Not a fit: Children with respiratory conditions, known allergies to essential oils or local anesthetics, systemic disease, recent sedative/analgesic use, or acute infections are excluded and unlikely to benefit from these interventions.

Why it matters

Potential benefit: If successful, these techniques could make tooth extractions less painful and less scary for children and improve cooperation during treatment.

How similar studies have performed: Previous research has shown aromatherapy can reduce anxiety in medical settings and that computer-controlled anesthesia devices can lessen injection discomfort, but combining these approaches for pediatric tooth extraction has limited prior evidence.
