Comparison of Erythritol Air-Polishing and Conventional Polishing Following Ultrasonic Scaling on the Relapse of Chromogenic Tooth Staining in Children

Condition(s) studied

Investigational drug(s) / intervention(s)

Guided Biofilm Therapy with erythritol: Description: Participants assigned to Group 1 will receive professional removal of chromogenic tooth staining using ultrasonic scaling followed by erythritol air-polishing with the EMS air-polishing device, guided by a plaque-disclosing agent. At the end of the procedure, the investigator will record the treatment time, apply the plaque-disclosing agent, obtain intraoral photographs, and assess chromogenic tooth staining using the Qraycam.

Conventional Polishing: Participants will undergo professional tooth cleaning using the ultrasonic scaler of the EMS device. The tooth surfaces will then be polished using a polishing brush and prophylaxis paste.

Study summary

The goal of this randomized clinical trial is to compare the effect of erythritol air-polishing and conventional polishing following ultrasonic scaling on the relapse of chromogenic tooth staining in children aged 4-13 years attending the Pediatric Dentistry Clinic of Marmara University Faculty of Dentistry for routine dental examination.

The main questions this study aims to answer are:

* Does erythritol air-polishing reduce the relapse of chromogenic tooth staining compared with conventional polishing following ultrasonic scaling?
* Is there a difference in the time to relapse of chromogenic tooth staining between the two polishing techniques?

Researchers will compare conventional polishing (prophylaxis paste and a polishing brush) following ultrasonic scaling with erythritol air-polishing performed using the EMS air-polishing device following ultrasonic scaling to determine whether one method is more effective in preventing or delaying the relapse of chromogenic tooth staining.

Eligibility

Primary outcome measure(s)

• Black Stain Score — Baseline, immediately after polishing, 1 month, 2 months, 3 months, and 6 months
  Black Stain Classification (Gasparetto et al., 2003) Score Description Clinical Characteristics 0 None No black pigmentation on the tooth surface. 1. Mild Pigmented dots or thin pigmented lines parallel to the gingival margin that are not continuous. 2. Moderate Continuous pigmented lines o extending over up to one-half of the cervical third of the tooth surface. 3. Severe Pigmentation extending over more than one-half of the cervical third of the tooth surface. Black Stain Classification (Zerman et al., 2024) Score Description A Pigmented lines or dots present only on the buccal surface. B Pigmented lines or dots present on both the buccal and lingual surfaces. C Pigmented lines or dots associated with dental caries. D Recurrent pigmented lines or dots.
• Participant Feedback — Periprocedural
  Pain perception during the procedure will be assessed using the Wong-Baker FACES Pain Rating Scale. The scale ranges from 0 to 10, where 0 indicates "no pain" and 10 indicates "hurts worst." Higher scores indicate greater pain intensity (worse outcome).
• Time Session — Periprocedural
  The duration of treatment is noted and compared between groups
