Eligibility
Inclusion criteria
Inclusion criteria: • Age: between 12-18 years for both sexes • Fully erupted permanent dentition having all teeth except third molars • Patients requiring fixed appliance in both arches • Patients having both extraction and non-extraction treatment protocols • Patients with stable mental health who can maintain good oral hygiene and maintain safety of brackets
Exclusion criteria
Exclusion criteria: • Patients with missing or extracted or planned extraction of any of the first permanent molars • Patients having first permanent molars with evidence of demineralization, caries, and developmental enamel defects • Patients with any buccal restorations in first permanent molars with amalgam /composite /glass ionomer cements/ crowns that may interfere with banding or bonding. • Patients having poor oral hygiene and evidence of periodontal disease exhibiting pocket depth more than or equal to 4mm, bleeding on probing score more than or equal to 30 % of sites, visible supragingival or subgingival calculus on examination. • Patients having malocclusions that could predispose to debonding bonded tubes such as severe deep bite, unilateral or bilateral posterior crossbite and severe crowding (> 8mm arch discrepancy • Patients who require extra oral and intra oral anchorage appliances in addition to fixed appliance such as head gear, transpalatal arches and temporary anchorage devices • Patients who need expansion of their arches using quad helix for correction of transverse discrepancy • Patients with craniofacial anomalies
Design outcomes
Primary
| Measure | Time frame |
|---|---|
| The overall success rate percentage=Number of successful attachments/Total number of treated sites x100 with regard to molar bands and molar tube. [at 6 months and 1 year] Periodontal health indicators: Bleeding on probing, presence of calculus, probing pocket depth with regard to molar bands and molar bands.For bleeding on probing and presence of calculus percentages will be calculated as Number of sites of the tooth with bleeding/presence of calculus /total number of sites assessed x 100 -Mean probing pocket depths will be compared among molar band and molar tubes groups . [ at baseline, 6-months and 1-year.] | — |
Secondary
| Measure | Time frame |
|---|---|
| Patient perceptions regarding molar bands versus molar tubes with regard to comfort, gingival swelling, bleeding during brushing, food impaction, cleaning difficulty, and overall preference. [In 6-months] Factors associated with success rate of cemented molar bands and bonded molar tubes such as age, gender, parent's occupation and malocclusion. [At the time of cementing molar bands or bonding molar tubes and in 1 year] | — |
