Brief Summary

The goal of this splith - mouth clinical trial is to compare 3D Printed Prefabric Composite Resin Crowns with Stainless Steel Crowns in healthy 50 children age between 5 and 9 with caries on more than one surface of the primary second molars. The main question\[s\] it aims to answer are:

• 3D printed composite resin crown's survival rate is as succesful as stainless steel crowns
• 3D printed composite resin crowns periodontal integrity is as succesful as stainless steel crowns Condition or disease : Carious Teeth Intervention/treatment: Procedure/Surgery: 3D Printed Prefabricated composite resin crown group Procedure/Surgery: Prefabricated stainless steel crown group

Conditions

Outcome Measures

Primary Outcomes (6)

• Comparison of clinical success

  According to the criteria reported by Santamaria et al. (2004), clinical success will be categorized as successful, major failure, and minor failure. Successful: No clinical signs or symptoms of pulp pathology Tooth has exfoliated (without any minor/major failures) No deformations in the crown/restoration No pathology observed in radiographs Minor failure: Reversible pulpitis (No need for root canal treatment or extraction) Crown/restoration loss that can be restored Presence of deformations/fractures/perforations in the crown/restoration Permanent crown remaining submerged Presence of new caries at the margins Major failure: Irreversible pulpitis Crown/restoration loss that cannot be restored Inter-radicular radiolucency Internal root resorption

• United States Public Health Service (USPHS): Retention, marginal compliance and gingival health criteria

  Restorations were evaluated to determine success according to modified United States Public Health Service (USPHS) criteria for marginal adaptation, marginal discolouration, secondary caries, anatomical form, retention, postoperative sensitivity and colour matching. Restorations with an "Alpha (A)" score were considered successful, those with a "Bravo (B)" score were considered acceptable, and those with a "Charlie (C)" score were considered unsuccessful. The scoring of the restorations was decided by agreement of both dentists (Ryge G. et al., 1980).

  24 Month

• Marginal Crown Gap

  (0) ¼ at the gingival margin, (1) ¼ below the gingival line (apical to the gingival margin) or (2) ¼ above the gingival line (occlusal to the gingival margin) \[Muhamed Altinawia et al., 1980\].

• Plaque Index (PI) (Silness and Loe, 1964)

  In this index, the thickness of dental plaque on the mesial, distal, vestibular, lingual tooth surfaces of all teeth or selected teeth and in relation to the gingiva is evaluated by probing. The values determined on the surfaces are summed and the plaque index value of the individual is obtained by taking the mathematical average. 0-No plaque in the area adjacent to the gingiva 1. There is a thin film on the edge of the gingival margin. This formation can only be detected with the help of a probe. 2. There is plaque in the gingival pocket and gingival margin at a level that can be determined by eye. There is no plaque in the aproximal area. 3. A large amount of plaque layer is observed in the gingival pocket and gingival margin. Interdental areas are filled with plaque.

• Gingival Index (GI) (Löe & Silness, 1963)

  It evaluates bleeding, which is the most basic sign of inflammation. The mesial, distal, vestibule and lingual sides of the teeth are evaluated. These values are then summed and divided by four. 0- Healthy gingiva, no inflammation 1. Mild inflammation, discolouration and mild oedema of the gums, no bleeding on probing 2. Moderate inflammation, redness and oedema of the gums, bleeding on probing 3. There is advanced inflammation, redness, oedema in the gum, spontaneous bleeding is observed.

• Simplified Oral Hygiene Index (OHI-S)

  Simplified Oral Hygiene Index (OHI-S) will be used to evaluate the plaque and calculus deposits of the patient and control groups. In this index, in order to simplify the oral hygiene index, six index teeth, which are considered representative of all anterior and posterior teeth, are evaluated. These teeth are teeth numbered 16, 26, 11, 31, 36, 46. The facial surfaces of teeth 16-26-11-31 and the lingual surfaces of teeth 36-46 are evaluated. This facilitation process is used both in the calculation of the debris index and in the calculation of the calculus index. After calculating the debris and calculus assessment indices, a simplified oral hygiene index is obtained (REF: 29.Greene, J.C., Vermillion, J.R.: The Simplified Oral Hygiene Index, J. Amer. Dent. Ass 68 : 7, 1960). The Simplified Oral Hygiene Index (OHI-S) Debris Index 0- No debris. 1. There is debris less than 1/3 of the tooth surface. 2. There is debris more than 1/3 and less than 2/3 of the tooth surface. 3. More

Eligibility Criteria

• Age: 5 Years - 9 Years
• Sex: all
• Healthy Volunteers: Yes
• Age Groups: Child (0-17)

You may qualify if:

• Healthy children aged 5-9 years with caries on second primary molars
• Children without systemic disease or developmental dental anomalies that may affect caries susceptibility.
• Children whose cooperation is 'positive' or 'absolutely positive' according to the Frankl behavioral scale (Frankl et al., 1962).
