Control groups will be formed in the 2-12 age group using standard manual toothbrushes, and the effectiveness of 360-degree bristle toothbrushes will be compared.

Study design: Experimental study

In this randomized controlled, single-brushing study, children were assigned to a treatment sequence involving a 360-degree toothbrush and a control brush.

Subjects were randomly assigned to a treatment sequence involving a 360-degree toothbrush and a classical manual control toothbrush. Parents brushed the teeth of their children aged 2-5 years, whereas children aged 6-12 years brushed their own teeth under the supervision of clinic staff, unaided by a mirror. Clinical examination of each participant was carried out by the principal investigator. Assessments were done pre- and post-brushing using the "Silness and Löe Plaque Index" (PI), Gingival Index (GI), and the Simplified Oral Hygiene Index (OHI-S). Plaque indices were expressed as means and standard deviations (SD). Within each toothbrush group, the follow-up scores were analyzed using a paired t-test. p < 0.05 was considered statistically significant.

Inclusion Criteria:

• Healthy children aged 2-12.
• Children without systemic disease or developmental dental anomalies.
• Children not undergoing orthodontic treatment.
• Children with no decay on the labial surfaces of upper anterior incisors.
• Patients or their parents accepting participation in the treatment.

Exclusion Criteria:

• Children with decay on the labial surfaces of upper anterior incisors.
• Children undergoing orthodontic treatment.
• Children who, along with their parents, do not agree to participate in the treatment will be excluded from the study.

The dental investigator who performed the oral health assessment for dentition status and plaque status was blinded during the intervention.
