Clinical performance of glass hybrid and short fiber-reinforced composite restorations in MIH-affected molars: A 60-month split-mouth randomized controlled trial.
Trial report in Clinical oral investigations, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT07733804 (Clinical Performance of Glass Ionomer and Composite Restorations in First Permanent Molars Affected by Molar Incisor Hypomineralization), which is not on this map. Not yet cited in PubMed.
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.

Abstract
objectivesThis study aimed to compare the 60-month clinical performance of glass hybrid (GH) and short fiber-reinforced composite (SFRC)-supported microhybrid composite restorations placed in MIH-affected first permanent molars following selective caries removal (SCR). MATERIALS AND
methodsThirty-one children (18 girls, 13 boys; 6-12 years) with MIH and at least two fully erupted first permanent molars exhibiting moderate-to-severe lesions (MIH-TNI scores 2 and 4) were enrolled. Following SCR, 62 molars were restored using a randomized split-mouth design. In each participant, one molar received a GH restoration (Equia Forte
resultsClinical performance deteriorated significantly over time for both materials (p < 0.001). GEE analysis showed no significant independent effect of material type on any modified USPHS criterion (p > 0.05), while time significantly affected retention, marginal adaptation, postoperative sensitivity, and secondary caries (p < 0.001). Kaplan-Meier analysis demonstrated significantly higher survival rates for SFRC-supported microhybrid composite than for GH restorations at 60-month (75.5% vs. 59.2%; p = 0.002).
conclusionsBoth GH and SFRC-supported microhybrid composite restorations provided clinically acceptable long-term outcomes in MIH-affected molars after SCR. Although clinical performance per modified USPHS criteria was comparable, SFRC-supported microhybrid composite restorations demonstrated superior long-term survival. CLINICAL RELEVANCE: When long-term durability is a primary consideration, SFRC-supported microhybrid composite restorations may be preferred for the restorative management of MIH-affected molars.
