Melissa Officinalis Aromatherapy for Dental Anxiety in Children (No acronym)
Anxiolytic Effect of Inhaled Melissa Officinalis Essential Oil During Mandibular Local Anesthesia in Pediatric Dental Patients: A Randomized Controlled Clinical Trial
This clinical study will look at whether a plant-based essential oil called "Melissa officinalis" (lemon balm) can help reduce fear and stress in children during dental treatment. Children between 6 and 10 years old who need a mandibular injection for a pulpotomy or pulpectomy will be invited to participate. They will be randomly assigned to one of three groups: one group will receive aromatherapy with *Melissa officinalis* from brand A, another group will receive the same essential oil from brand B, and a third group will receive the usual behavioral management used in pediatric dentistry, but without aromatherapy.
The essential oil will be diffused in the dental room so that the child can gently inhale the aroma starting a few minutes before the injection and throughout the procedure. The study team will measure the child's dental anxiety using a child-friendly questionnaire with drawings of faces, observe pain behaviors during the injection, and record the child's own rating of pain with a faces scale. Heart rate and oxygen saturation will also be monitored as objective signs of stress. The goal is to find out whether "Melissa officinalis" aromatherapy is a safe, simple, non-invasive way to make dental visits less stressful and more comfortable for children, and whether there are meaningful differences between the two commercial products.

Descrição detalhada
This is a single center, three arm, parallel group, randomized controlled trial in pediatric dental patients. Participants will be randomized in equal proportions (1:1:1) to one of three groups using permuted blocks, with allocation concealed in sequentially numbered, opaque, sealed envelopes prepared by an independent investigator. Due to the olfactory nature of the intervention, blinding of operators is not feasible; however, outcome assessors who record anxiety, pain scores, and physiological measures will be distinct from the operator and will remain unaware of group allocation until data analysis.
All clinical procedures will be performed by a single calibrated pediatric dentist using a standardized protocol that includes topical lidocaine 10% spray, inferior alveolar nerve block with lidocaine 2% with epinephrine 1:100,000, and subsequent pulpotomy or pulpectomy as indicated. Behavioral management techniques (tell-show-do, positive reinforcement, age appropriate language, and modeling when needed) will be applied in all groups, with the control group receiving only these non pharmacological strategies and no aromatherapy.

Experimental: Aromatherapy with Melissa officinalis essential oil - Brand A
Children will receive aromatherapy with Melissa officinalis essential oil (Brand A) in addition to standard non pharmacological behavioral management during a mandibular local anesthetic procedure for pulpotomy or pulpectomy. A standardized dilution of Melissa officinalis essential oil from Brand A (Young Living, Lehi, Utah, USA) in 10 milliliters of sterile distilled water will be added to an electric nebulizer in the dentist office. Diffusion will begin five minutes prior to the topical anesthetic and inferior alveolar nerve block being administered, and it will continue during the pulpotomy or pulpectomy process. Additionally, age-appropriate communication, positive reinforcement, and tell-show-do behavioral control techniques will be employed. |
Melissa officinalis essential oil from Brand A (Young Living, Lehi, Utah, USA) will be placed in an electric nebulizer in the dental operatory at a standardized dilution in 10 mL of sterile distilled water.
Diffusion will start 5 minutes before administration of topical anesthetic and inferior alveolar nerve block and will continue throughout the pulpotomy or pulpectomy procedure.
Conventional behavioral management (tell-show-do, positive reinforcement, age appropriate communication) will also be used.

Experimental: Aromatherapy with Melissa officinalis essential oil - Brand B
Children will receive aromatherapy with Melissa officinalis essential oil (Brand B) in addition to standard non pharmacological behavioral management during a mandibular local anesthetic procedure for pulpotomy or pulpectomy. The same nebulizer model, timing, and circumstances as the Brand A arm will be utilized to give Melissa officinalis essential oil from Brand B (doTERRA, Pleasant Grove, Utah, USA) (5 minutes before and during local anesthesia and treatment). In every situation, traditional behavioral management will be used. |
Melissa officinalis essential oil from Brand B (doTERRA, Pleasant Grove, Utah, USA) will be administered with the same nebulizer model and under the same conditions and timing used in the Brand A arm (5 minutes before and during local anesthesia and treatment).
Conventional behavioral management will be applied in all cases.

Comparador Ativo: Standard behavioral management
Children will receive standard non pharmacological behavioral management during the mandibular local anesthetic procedure and restorative treatment, with no aromatherapy or additional olfactory stimulus in the operatory. Without the use of essential oils, behavioral strategies such as tell-show-do, positive reinforcement, euphemistic language, and modeling where necessary will be employed to promote compliance during local anesthetic and pulpotomy or pulpectomy. |
Behavioral techniques including tell-show-do, positive reinforcement, euphemistic wording, and modeling when needed will be used to facilitate cooperation during local anesthesia and pulpotomy or pulpectomy, without the use of essential oils.

Descrição da medida |
Prazo |
|---|---|---|
|
Change in dental anxiety (MCDASf score)
Prazo: From baseline before the dental appointment to immediately after local anesthetic injection (approximately 15-20 minutes).
|
Dental anxiety will be assessed using the Modified Child Dental Anxiety Scale with faces (MCDASf).
Scores will be recorded at baseline (before exposure to the operatory or aromatherapy) and after completion of local anesthetic injection.
The outcome is the change in MCDASf score (post anesthesia minus baseline) and will be compared among the three study groups.

Medida de resultado |
Descrição da medida |
Prazo |
|---|---|---|
|
Observed pain during needle insertion (SEM scale)
Prazo: During needle insertion and anesthetic injection (approximately 1-2 minutes).
|
Pain behavior during administration of the inferior alveolar nerve block will be evaluated using the Sound, Eye, Motor (SEM) scale by an independent, trained observer.
Higher scores indicate more intense behavioral signs of pain.
|
During needle insertion and anesthetic injection (approximately 1-2 minutes).
|
|
Self reported pain after treatment (Wong-Baker Faces)
Prazo: Immediately after completion of pulpotomy or pulpectomy (within 5-10 minutes).
|
After completion of the dental procedure, children will rate their pain using the Wong-Baker Faces Pain Rating Scale (0-10).
Higher scores indicate greater perceived pain intensity.
|
Immediately after completion of pulpotomy or pulpectomy (within 5-10 minutes).
|
|
Heart rate during dental treatment
Prazo: Baseline, during injection, and post treatment (total monitoring period approximately 20-30 minutes).
|
Heart rate will be measured with a digital pulse oximeter at three time points: baseline (seated in the operatory), during the local anesthetic injection, and after completion of treatment.
The outcome will be the mean heart rate and its change across time points within and between groups.
|
Baseline, during injection, and post treatment (total monitoring period approximately 20-30 minutes).
|
|
Oxygen saturation during dental treatment
Prazo: Baseline, during injection, and post treatment (approximately 20-30 minutes).
