Abstract
Background:
The molar incisor hypomineralization (MIH) is a developmental enamel defect which affects the first permanent molar and commonly the permanent incisors, the defect can make the patient face a lot of difficulties like sensitivity, rapid caries progression and poor esthetics.
Aim:
To Compare two different techniques of management of first permanent molar defects in MIH patients regarding the longevity of the crowns, gingival health, marginal integrity and recurrent caries for nine months. The two techniques are two types of crowns (CAD-CAM milled PMMA versus Cast adhesive Metal Coping (CAC)).
Method:
60 molars were selected and randomly allocated into two groups.one received CAD-CAM milled PMMA crown and the second received CAC. The crowns were evaluated for longevity, marginal integrity, recurrent caries and gingival health at 1, 3, 6 and 9 months.
Results:
The study showed a highly significant difference between the two groups regarding the longevity in both 1st and 6th months follow ups and no significant differences between the two groups regarding marginal integrity, recurrent caries and gingival health on all follow up visits.
Conclusion:
Cast adhesive metal coping can be used as a restoration for first permanent molars affected by MIH and despite the esthetic advantage of the PMMA CAD-CAM milled crown and its excellent marginal fit, it needs more research to increase the retention.
