Tooth decay in young children, especially poor children, is very common. It affects billions of children worldwide. Tooth decay can have long‐lasting effects on health and it can cost a lot to treat it. Dental plaque is bacteria in the mouth, and it is well known that it causes tooth decay, along with sugar. The attitudes, beliefs, and habits of pregnant women, mothers and other people looking after children can influence the dental health of their children. Continue reading
Tooth decay (caries) is a widespread disease, affecting billions of people worldwide. Fluoride has long been used to prevent decay, through a variety of different methods including toothpaste, water, milk, mouthrinses, tooth gels and varnish. Regular toothbrushing is recommended to prevent decay and other oral diseases, and toothbrushing for 2 minutes twice daily with a fluoride toothpaste is generally recommended. The typical strength of regular or family toothpaste is around 1000 to 1500 parts per million (ppm) fluoride, but many other strengths are available worldwide. There is no minimum fluoride concentration, but the maximum permissible fluoride concentration for a toothpaste varies according to age and country. Higher concentrations are rarely available over the counter, and are classed as a prescription‐only medicine. Stronger fluoride toothpaste may offer greater protection against decay but also increases the risk of fluorosis (enamel defects) in developing teeth. This is an update of the Cochrane Review first published in 2010. Continue reading
Tooth decay is one of the most common diseases in children. Tooth decay in the primary or milk teeth tends to progress rapidly, and it often reaches the pulp. Dental pulp consists of nerves, tiny blood vessels and connective tissue that make up the centre of a tooth. Symptoms of this extensive tooth decay include pain, swelling and abnormal tooth movement.
Dentists often have to perform one of three pulp treatment techniques to resolve the problem:
- Direct pulp capping: where a healing agent is placed directly over the exposed pulp. The most common materials used for direct pulp capping are calcium hydroxide, mineral trioxide aggregate, formocresol or an adhesive resin, placed directly over the tooth’s nerve.
- Pulpotomy: removal of a portion of the pulp. After a pulpotomy, one of four materials is generally used to fill the cavity: ferric sulphate, formocresol, calcium hydroxide or mineral trioxide aggregate.
- Pulpectomy: removal of all of the pulp in the pulp chamber and root canal of a tooth. After a pulpectomy, a material is put into the space created by pulp removal.
This review looks at the three techniques, and the effectiveness of different materials (known as medicaments) for pulp capping, pulpotomy and pulpectomy. Continue reading
Tooth decay is not distributed evenly among the population, with certain groups being at greater risk of developing tooth decay than others. For example, research in Scotland has shown that 50% of tooth decay occurs in 11% of 5-year-old children and only 6% of 14-year-old children. In light of this uneven distribution, it is often suggested that these small percentages of children may be offered targeted-caries preventive measures to great potential effect, in a cost effective manner. One such preventive measure is the use of slow-release fluoride devices (e.g. slow-dissolving fluoride-releasing glass beads). Continue reading
Tooth decay is one of the most common health problems among children. If fluoride supplements taken by pregnant women can prevent tooth decay in their children, pregnant women with no access to a fluoridated drinking water supply can obtain the benefits of systemic fluoridation. Fluoride tablets, drops, lozenges or chewing gums are sucked or chewed to provide topical fluoride and ingested to provide systemic fluoride. Continue reading
Although children and adolescents have healthier teeth than in the past, tooth decay (also known as caries) is a problem in some people and places. Most tooth decay in young people occurs on the biting surfaces of back teeth. Tooth decay prevention includes brushing, fluoride supplements (such as tablets), fluoride directly applied to the teeth and dental sealants. Dental sealants aim to prevent bacteria growth that promote tooth decay in grooves of back teeth. Sealants are applied by dentists or dental care team members. The main types used are resin-based sealants and glass ionomer cements. Continue reading
Tooth decay is a health problem worldwide, affecting the vast majority of adults and children. Levels of tooth decay vary between and within countries, but children in lower socioeconomic groups (measured by income, education and employment) tend to have more tooth decay. Untreated tooth decay can cause progressive destruction of the tops of teeth (crowns), often accompanied by severe pain. Repair and replacement of decayed teeth is costly in terms of time and money and is a major drain on the resources of healthcare systems.
Preventing tooth decay in children and adolescents is regarded as a priority for dental services and is considered more cost-effective than treatment. Use of fluoride, a mineral that prevents tooth decay, is widespread. As well as occurring naturally, fluoride is added to the water supply in some areas, and is used in most toothpastes and in other products that are available to varying degrees worldwide. As an extra preventive measure, fluoride can be applied directly to teeth as mouthrinses, lozenges, varnishes and gels.
Fluoride mouthrinse has frequently been used under supervision in school-based programmes to prevent tooth decay. Supervised (depending on the age of the child) or unsupervised fluoride mouthrinse needs to be used regularly to have an effect. Recommended procedure involves rinsing the mouth one to two minutes per day with a less concentrated solution containing fluoride, or once a week or once every two weeks with a more concentrated solution. Because of the risk of swallowing too much fluoride, fluoride mouthrinses are not recommended for children younger than six years of age.
This review updates the Cochrane review of fluoride mouthrinses for preventing tooth decay in children and adolescents that was first published in 2003. Continue reading
