Pediatric dentistry requires procedures with good long-term durability, due to the difficulty of working with young patients. Additionally, fear of dentistry and poor cooperation is common in pediatric dentistry. Therefore, simple procedures, like crowns, are an excellent choice and have excellent long-term prognosis.
The traditional method for management of dental caries has evolved from the exclusive domain of techniques based on complete caries removal prior to tooth restoration. Norna Hall used pre-formed crowns and cemented over carious primary molars using a glass-ionomer luting cement, with no caries removal, tooth preparation, or local anaesthesia.
The dental papilla contains cells that develop into odontoblasts, which are dentin-forming cells. [3] Additionally, the junction between the dental papilla and inner enamel epithelium determines the crown shape of a tooth. [2] The dental follicle gives rise to three important entities: cementoblasts, osteoblasts, and fibroblasts. Cementoblasts ...
A crown may be needed when a large dental cavity threatens the health of a tooth. Some dentists will also finish root canal treatment by covering the exposed tooth with a crown. [1] A crown is typically bonded to the tooth by dental cement. They can be made from various materials, which are usually fabricated using indirect methods. Crowns are ...
Enamel hypoplasia is a risk factor for dental caries in children including early childhood caries (ECC), which continues to be a burden for many children. This association has been identified as significant and independent, and is believed that the formation of pits and missing enamel provides a suitable local environment for adhesion and ...
A common one used amongst children with caries is a preformed metal crown (PMC). This type of crown is pressed over a decayed tooth without any preparation, local anaesthetic or caries removal, also termed the Hall technique. Studies have shown that more dental practitioners prefer conventional fillings as opposed to PMC’s.
They represent the incremental pattern of enamel, the successive apposition of different layers of enamel during crown formation. Striae of Retzius visible on the lower incisors of a 26-year-old patient. There are 3 types of incremental lines: Daily incremental lines (cross striation), striae of Retzius and neonatal lines.
A post and core crown is a type of dental restoration required where there is an inadequate amount of sound tooth tissue remaining to retain a conventional crown. A post is cemented into a prepared root canal, which retains a core restoration, which retains the final crown. [1] [2]
