Results from a five-year clinical assessment of undergraduate-performed direct composite restorations.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Resin based dental composites offer significant benefits with regard to the minimally invasive management of dental caries. However, over a period of time such restorations may become susceptible to failure with secondary caries and marginal deterioration being common causes. A retrospective clinical study was conducted at the IMU University Oral Health Centre to assess the quality of direct resin composite restorations placed by dental undergraduates as judged by the modified United States Public Health Service (USPHS), criteria. This study aimed to evaluate the quality and the causes of the failure of direct resin composite restorations in permanent teeth placed by dental undergraduate students using modified USPHS criteria to assess failure. A total of 76 restorations were evaluated in this study. Descriptive statistics were collected, and the Chi-square test (p < 0.05) was used to determine statistically significant differences. A total of 42.1% of the composite resin restorations in the study were considered satisfactory. Of the restorations regarded as failures, the causes were colour mismatch (39.4%), followed by marginal discolouration (21%) and then restoration fracture (14.5%). The operator's year of study (p = 0.039) and the number of restoration surfaces (p = 0.039) showed statistically significant associations with the quality of the restorations. Composite resin restorations performed by dental undergraduates exhibited high failure rates, which were primarily attributed to colour mismatches, marginal dis-colourations, or fractures of the restoration.
