The control group will be given no intervention other than they will receive routinely

Arm Description: The oral health promotion intervention will be implemented through weekly interactive sessions lasting 30-40 minutes over a period of six months. These sessions, conducted by trained dental educators and teachers, will use animations, storytelling, demonstrations, and role-plays to teach proper toothbrushing, the importance of fluoride toothpaste, healthy eating habits, and the need for regular dental visits. Children will participate in supervised toothbrushing once a week, supported by peer ambassadors who reinforce daily practices. Educational leaflets and videos will engage parents, while posters in classrooms serve as reminders. Follow-up assessments, including questionnaires and clinical indices, will be conducted at six months.

Plaque score index: 0: No plaque.

1. Separate flecks of plaque at the gum line.
2. A thin band of plaque along the gum line.
3. A band of plaque wider than 1mm but covering less than one-third of the tooth.
4. Plaque covering one-third to two-thirds of the tooth.
5. Plaque covering more than two-thirds of the tooth. Higher scores indicate more plaque and poorer oral hygiene.

Oral Hygiene will be assessed by the presence of debris (plaque) and calculus (tartar) on selected tooth surfaces, measured by the Simplified Oral Hygiene Index (OHI-S)

Individual Debris Index (DI-S) and Calculus Index (CI-S):

Each of the six surfaces is scored individually for both debris and calculus using a 0-3 scale:

0: No debris or calculus is present.

1. Debris or calculus covers less than one-third of the surface.
2. Debris or calculus covers between one-third and two-thirds of the surface.
3. Debris or calculus covers more than two-thirds of the surface. Good: 0.0 - 1.2 Fair: 1.3 - 3.0 Poor: 3.1 - 6.0

Gingival score assessed by the gingival score index:

0: Normal gingiva, no inflammation.

1. Mild inflammation - slight color change and edema (swelling), no bleeding on probing.
2. Moderate inflammation - redness, edema, glazing, and bleeding on probing.
3. Severe inflammation - marked redness, edema, ulceration, and tendency towards spontaneous bleeding. The index typically uses a scale of 0 to 3, with 0 representing normal gingiva and higher scores indicating increasing severity of inflammation

Oral health practices by using the WHO Child Oral Health Questionnaire: o assess children's oral health practices through a structured set of questions. These questionnaires typically cover knowledge, attitude, and practices related to oral hygiene, including frequency of brushing, use of fluoride toothpaste, and dental visits. The score is used to evaluate the overall oral health practices of the child, often categorized as good, fair, or poor.
