Arms and Interventions

Arm Intervention/Treatment
Experimental: Hall Technique (HT)

Device: Hall Technique (HT)
Prior to each restoration, a bacterial sample of the lesion will be obtained with a cotton swap and dispensed in a transport medium for microbial analyses.The preformed metal crown (PMC) will placed without local anesthetic and without crimping or trimming. When the contact points are tight, an orthodontic elastic separator will be placed for 2 hours prior to PMC placement. The PMCs will be cemented with glass ionomer Ketac cem.

Experimental: Modified Hall Technique (MHT)

Device: Modified Hall Technique (MHT)
Prior to each restoration, a bacterial sample of the lesion will be obtained with a cotton swab and dispensed in a transport medium for microbial analyses.This group will in addition to all the procedures for the Hall will have the Caries lesions treated with 30% Silver Diamine Fluoride (SDF) before cementation of the stainless-steel crowns.

Active Comparator: Conventional Technique (CT)

Device: Conventional Technique (CT)
Prior to each restoration, a bacterial sample of the lesion will be obtained with a cotton swab and dispensed in a transport medium for microbial analyses. Conventional occlusal, proximal slicing and when necessary buccal and lingual surfaces will be carried out under local anesthesia and dental dam isolation local anesthesia.The PMC will be trimmed and crimped at the gingival margin to improve the fit, and cemented with Ketac cem.

Outcome Measures

Primary Outcome Measures

  1. Success as assessed by number of participants with no coronal or peri-radicular pathology [3 months post intervention]

  2. Success as assessed by number of participants with no coronal or peri-radicular pathology [6 months post intervention]

  3. Success as assessed by number of participants with no coronal or peri-radicular pathology [9 months post intervention]

  4. Success as assessed by number of participants with no coronal or peri-radicular pathology [12 months post intervention]

  5. Amount of time taken to complete the intervention [from start of intervention to end of intervention (about 45 minutes to 11/2 hours)]

Secondary Outcome Measures

  1. Number of participants with occlusal contact of the molars as assessed by the strip test [3 months post intervention]

    Measured by passing a strip between the contra-lateral upper and lower posterior natural teeth with the child biting into maximum intercuspation. If the strip passes without resistance between teeth anterior or posterior to the SSC there is no occlusal contact.

  2. Number of participants occlusal contact of the molars as assessed by the strip test [6 months post intervention]

    Measured by passing a strip between the contra-lateral upper and lower posterior natural teeth with the child biting into maximum intercuspation. If the strip passes without resistance between teeth anterior or posterior to the SSC there is no occlusal contact.

  3. Number of participants occlusal contact of the molars as assessed by the strip test [9 months post intervention]

    Measured by passing a strip between the contra-lateral upper and lower posterior natural teeth with the child biting into maximum intercuspation. If the strip passes without resistance between teeth anterior or posterior to the SSC there is no occlusal contact.

  4. Number of participants occlusal contact of the molars as assessed by the strip test [12 months post intervention]

    Measured by passing a strip between the contra-lateral upper and lower posterior natural teeth with the child biting into maximum intercuspation. If the strip passes without resistance between teeth anterior or posterior to the SSC there is no occlusal contact.

  5. Molar height in occlusion [3 months post intervention]

  6. Molar height in occlusion [6 months post intervention]

  7. Molar height in occlusion [9 months post intervention]

  8. Molar height in occlusion [12 months post intervention]

  9. Anterior occlusal contact [3 months post intervention]

    Over lap of the upper and lower incisors will be measured in millimeters.If incisors are missing, canines will be used.

  10. Anterior occlusal contact [6 months post intervention]

    Over lap of the upper and lower incisors will be measured in millimeters.If incisors are missing, canines will be used.

  11. Anterior occlusal contact [9 months post intervention]

    Over lap of the upper and lower incisors will be measured in millimeters.If incisors are missing, canines will be used.

  12. Anterior occlusal contact [12 months post intervention]

    Over lap of the upper and lower incisors will be measured in millimeters.If incisors are missing, canines will be used.

  13. Biofilm around the stainless steel crown as assessed by the Modified Plaque Index [3 months post intervention]

    In the Modified Plaque Index, a score of 0 (no plaque), 1 (thin visible plaque, difficult to identify), or 2 (thick visible plaque, easily detected) is assigned

  14. Biofilm around the stainless steel crown as assessed by the Modified Plaque Index [6 months post intervention]

    In the Modified Plaque Index, a score of 0 (no plaque), 1 (thin visible plaque, difficult to identify), or 2 (thick visible plaque, easily detected) is assigned

  15. Biofilm around the stainless steel crown as assessed by the Modified Plaque Index [9 months post intervention]

    In the Modified Plaque Index, a score of 0 (no plaque), 1 (thin visible plaque, difficult to identify), or 2 (thick visible plaque, easily detected) is assigned

  16. Biofilm around the stainless steel crown as assessed by the Modified Plaque Index [12 months post intervention]

    In the Modified Plaque Index, a score of 0 (no plaque), 1 (thin visible plaque, difficult to identify), or 2 (thick visible plaque, easily detected) is assigned

  17. Gingival health of the treated tooth as assessed by gingival status score [3 months post intervention]

    Gingival status is assigned a score of 0 (normal gingiva, natural coral pink gingival with no e/o inflammation), 1 (mild inflammation, slight changes in color, slight edema, no bleeding on probing), 2 (moderate inflammation, redness, edema, and glazing, bleeding on probing), or 3 (severe inflammation, marked redness and edema/ulceration/tendency to bleed spontaneously).

  18. Gingival health of the treated tooth as assessed by gingival status score [6 months post intervention]

    Gingival status is assigned a score of 0 (normal gingiva, natural coral pink gingival with no e/o inflammation), 1 (mild inflammation, slight changes in color, slight edema, no bleeding on probing), 2 (moderate inflammation, redness, edema, and glazing, bleeding on probing), or 3 (severe inflammation, marked redness and edema/ulceration/tendency to bleed spontaneously).

  19. Gingival health of the treated tooth as assessed by gingival status score [9 months post intervention]

    Gingival status is assigned a score of 0 (normal gingiva, natural coral pink gingival with no e/o inflammation), 1 (mild inflammation, slight changes in color, slight edema, no bleeding on probing), 2 (moderate inflammation, redness, edema, and glazing, bleeding on probing), or 3 (severe inflammation, marked redness and edema/ulceration/tendency to bleed spontaneously).

  20. Gingival health of the treated tooth as assessed by gingival status score [12 months post intervention]

    Gingival status is assigned a score of 0 (normal gingiva, natural coral pink gingival with no e/o inflammation), 1 (mild inflammation, slight changes in color, slight edema, no bleeding on probing), 2 (moderate inflammation, redness, edema, and glazing, bleeding on probing), or 3 (severe inflammation, marked redness and edema/ulceration/tendency to bleed spontaneously).
