The diagnosis of the integrity of the marginal ridge in primary molars is important in treatment planning for children cheap cafergot 100 mg amex. Research has shown that once the marginal ridge of a primary molar has broken away the pulp of the tooth is affected and irreversible changes have commenced (Fig cheap cafergot 100mg free shipping. Radiographs The importance of radiographs for the diagnosis of caries in children cannot be over- emphasized buy cafergot 100mg on-line, as clinical examination alone would mean that many proximal lesions could be missed (Fig. As mentioned earlier many early lesions may be halted or reversed by a rigorous preventive programme. Radiographs should form a routine part of any dental examination and it is necessary to repeat radiographs for dental caries diagnosis at suitable intervals. The intervals that are appropriate to children vary according to the level of caries that a child presents with. Key Point Destruction by caries of the marginal ridge of a primary molar indicates likely pulpal involvement. It used to be felt that multiple short visits placed least stress on a child particularly if they were under 6 years of age. However, the most important aspect of child management is to gain the confidence of the child and make sure that there is as little discomfort as possible. Local analgesia is therefore mandatory and is easily performed these days with topical analgesia, fine gauge needles, and short-acting local analgesia agents. Due consideration should be given to the use of a rubber dam that ensures a much higher quality of restorations that last for the duration of a tooth as well as being an aid in behaviour management. Once the tissues have been anaesthetized and the child is confident that there will be no pain, it is usually best to complete treatment on a whole quadrant. The number of visits can then be kept to a minimum and a reservoir of co-operation maintained. Where there is pulpal involvement of primary teeth then pulpotomies or pulpectomies are essential. No doubt, the least interventionist approach can be the correct one for some children, but integrated within a treatment plan which is best in the long-term interest of the child and not an easy way out for the dentist. If this predisposes the child to repetitive treatment, and worse still pain, abscesses, and extractions under general anaesthesia, then it should be rejected in favour of comprehensive care using restorative techniques, such as described in this chapter. Treatment decisions ought to be based on sound scientific evidence but, unfortunately, despite the great effort that has been spent providing treatment over many years, little in the way of resources has been spent on clinical research into the success or otherwise of dental treatment methods. There are few reports in the literature on the relative success in the primary dentition of different treatment methods or materials. The majority of those reports are retrospective and therefore need to be treated with caution. The choice of restoration for primary teeth is based upon the degree of carious involvement, whether the marginal ridge is intact or not and the length of time that will elapse before exfoliation. The decision regarding the type of restoration to be used is therefore based on the diagnosis of the extent of the dental caries. Therefore the popularity of any particular material has depended on clinical impression and fashion. This section provides a brief overview of those materials that are both currently widely available and have been subject to some clinical research. Silver amalgam Silver amalgam has been used for restoring teeth for over 150 years and, despite the fact that it is not tooth coloured and that there have been repeated concerns about its safety (largely unfounded), it is still widely used. This is probably because it is relatively easy to use, is tolerant of operator error, and has yet to be bettered as a material for economically restoring posterior teeth. Modern, non-gamma 2 alloy restorations have been shown to have extended lifetimes in permanent teeth when placed under good conditions, and have also been shown to be much less sensitive to poor handling than tooth-coloured materials. In clinical trials and retrospective studies, no intracoronal material has so far performed more successfully than amalgam. Stainless-steel crowns These were introduced in 1950 and have gained wide acceptance in North America. In Europe they have been less popular, being seen by most dentists as too difficult to use, although in reality they are often easier to place than some intracoronal restorations (Fig. All published studies have shown stainless-steel crowns to have a higher success rate in primary teeth than all other restorative materials. They are certainly the preferred treatment option for first primary molars with anything other than minimal caries. Stainless-steel crowns are also advocated for hypoplastic or very carious first permanent molars, where they act as provisional restorations prior either to strategic removal at age 9-12 years or later restoration with a cast crown (Fig. Etched retained castings may now be used for the definitive restoration of permanent hypoplastic teeth without involvement of the approximal surface; more conservative provisional restorations than stainless-steel crowns should be considered if this is intended. Composite resin Composite resins came on the market in the early 1970s and have been modified since then in an attempt to improve their properties.
