ABSTRACT
@#Dental caries and trauma are the most common oral diseases in children, which could result in defects of the teeth or detention. Maintenance of the primary dentition in a nonpathologic condition is important for oral health, craniofacial development, and the overall well-being of the children. In contemporary dentistry, primary anterior teeth defects are mainly treated with drugs, restorative treatments, or both. Restorative treatment is the most preferred method and includes direct restoration, full coronal restoration, post-and-core crowns, etc. This article reviews the available information regarding a variety of restorative treatments for primary incisor defects, including their backgrounds, clinical indications, clinical pathways, and related studies. The literature review shows that intraconal direct restoration is widely used on single surfaces. There are many kinds of full coronal restorations, and each has its own advantages. Pediatric resin-bonded strip crowns and zirconia crowns are the most popular and have excellent aesthetics. The use of post-and-core crowns for primary incisors is controversial. The absorbable post may be the next research hotspot. Therefore, treatment of severely destroyed primary incisors poses a challenge for pediatric dentists, as three important considerations must be kept in mind: children′s behavioral management, preservation of the tooth structure and parental satisfaction.
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 differencein the marginal adaptation between the two groups (x2 =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 (x2 =5.027,P =0.025;secondary caries x2 =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.
