Abstract
Objective To explore the feasibility and effectiveness of aesthetic restoration of caries of mandibular deciduous incisors with strip crown form of maxillary deciduous incisors. Methods A total of 64 patients (202 teeth) with symmetrical caries of bilateral mandibular central incisors or lateral incisors were randomly selected. The opposite maxillary incisors were restored with strip crowns form and the opposite incisors were restored with resin composite. The effects of the two methods and the incidence of complications were compared three months, six months and twelve months after treatment. Results Three months after treatment, there was no significant difference in the success rate between the two groups. Six months after treatment, there was significant difference in the marginal adaptation between the two groups (χ2=3.919, P =0.048); 12 months after treatment, there was significant difference in the restoration integrity of the two groups and the incidence of secondary caries (χ2=5.027, P=0.025; secondary caries χ2=4.369, P=0.037 ). Conclusions The strip crown form of maxillary primary incisors can be used for aesthetic restoration of caries of mandibular primary incisors, and its effect is better than that of direct resin filling. The strip crown form for mandibular primary incisors needs to be developed and produced urgently.
