Brief summary
The aim of this study was to compare the clinical performance of direct restorations with two different indirect composite systems in primary teeth.
Detailed description
The aim of this study was to compare the clinical performance of a thermoviscous bulk-fill composite used in direct restorations with two different indirect composite systems in primary teeth. This randomized, controlled, assessor-blind, parallel-group design in vivo study included 158 teeth from 73 patients aged 4-10 years. The teeth were allocated into three groups: direct thermoviscous bulk-fill composite, indirect nano-hybrid composite inlay system, and indirect nano-hybrid modular composite system. Clinical evaluations were performed according to FDI criteria at 6- and 12-month follow-up, and survival comparisons were conducted.
Interventions
The clinical performance of restorations was evaluated using Fédération Dentaire Internationale (FDI) criteria. Restorations were assessed across functional (fracture and retention, marginal adaptation), biological (postoperative sensitivity, recurrent caries, tooth integrity, and periodontal response), and esthetic (surface polish, marginal and surface staining) domains using a five-point scale. Scores of 1-3 were considered clinically acceptable, whereas scores of 4-5 were considered clinically unacceptable and indicative of failure
For survival comparisons, restoration failure was defined as total or partial loss of the restoration or a clinically unacceptable score according to FDI criteria. Restorations maintaining acceptable clinical performance throughout the follow-up period were considered successful.

Study design
Masking description
The study was carried out as a one-blinded trial, which the outcomes assessor was unaware of what material was applied to each tooth. No blinding was done during the treatment period because all treatments were performed by one dentist.
Intervention model description
This randomized, controlled, parallel design, assessor-blind study was conducted under in vivo conditions to compare the clinical performance of direct and indirect restorations applied to carious primary molar teeth.
Eligibility
Inclusion criteria
* children aged between 4 and 10 years, * classified as ASA I according to the American Society of Anesthesiologists (i.e., healthy individuals without systemic disease except for conditions not affecting general health), * demonstrating cooperative behavior corresponding to Frankl Behavior Rating Scale scores of 3 (positive) or 4 (definitely positive). * Only patients presenting with Angle Class I occlusion * demonstrating bilateral, balanced mastication were included in the study. * Teeth included in the study were required to present with Class II (MO/DO) cavities and to have an antagonist and proximal contact. * According to the International Caries Detection and Assessment System II (ICDAS II), teeth with scores of 4, 5, or 6 were included. * In addition, only teeth with a plaque index score of 0 (no plaque) or 1 (plaque not visible to the naked eye but detectable with a probe at the gingival margin) * a gingival index score of 0 (healthy gingiva, no inflammation) were selected
Exclusion criteria
* patients who do not meet the inclusion criteria * teeth that do not meet the inclusion criteria * Teeth showing internal and external resorption on radiographic examination * Patients/guardians who declined to participate in the study and participants who did not sign the consent form
