Plaque disclosing tablets and solutions are available for children. Children need close supervision when using these agents and appropriate advice should be given to parents and guardians. Plaque charts can be used to monitor progress and to identify areas where cleaning is not ideal. After demonstrating the plaque disclosing procedure and performing the charting it is initially advisable to instruct patients to use the disclosing agent prior to toothbrushing. After 1 week it is advisable for patients to brush first and then disclose in order to identify areas that are being missed. Toothbrushing: Advise regular toothbrushing with an appropriate concentration of ______ toothpaste.

Toothbrushing should become a routine and on at least two occasions every day. Manual toothbrushes Electric toothbrushes Toothbrushes should be small head. Young children under 8 years need help with toothbrushing. Children do not have the manual dexterity to brush their teeth effectively until they can tie their own shoelaces. Up to age 8, parents/ caregivings are responsible from the brushing procedures of children. They have to first let the child to brush her/his teeth as she/he knows. Then parents/ caregivings brush the teeth. Dentists should show which brushing tecnique should be used.Fone technique is appropriate for children. The buccal and lingual surfaces should brushed in a circular motion 5 times / tooth. Occlusal surfaces should be brushed same. The toothbrush should be kept in an upright position at labial/ lingual surfaces. parent assiting Only a small smear of ______ toothpaste should be used up to 3 years of age then pea size could be advised.

The night-brushing should be start half an hour before going to sleep to avoid moodiness. After brushing advice not to eat or drink until sleep. Children between 8-12 years old should be educated by the dentist about toothbrushing technique. Parents/caregivings should observe and control the brushing. Modified Bass Technique: The most commonly recommended method is the Modified Bass technique, which involves holding the toothbrush at an 45 angle so that the bristles point at gum line and making short back-and-forth strokes, followed by sweeping the brush from under the gum toward the edge of tooth. 2) Nutrition and diet in caries control: Advising parents to completely stop their children from eating sugary foods is not achievable. We should advise that only milk or water is given to children in a baby bottle. Many are not aware that no added sugar drinks contain natural sugar. 'Safer foods' have been recommended as alternatives for frequent snackers or nibblers. These alternatives include cheeses that have been shown to raise plaque pH. In addition to fruit and vegetables, crisps and peanuts have also been recommended as safer alternatives. Frequency of eating: Frequency of eating has an important effect on teeth. Eating meals leads to periods of acid attack when tooth mineral is lost. At the end of the meal or snack the acid is buffered by saliva and the mineral loss stops and reverses under favourable conditions. Frequent snackers have predominantly mineral loss and little if any remineralization. Brushing twice per day with a ______ toothpaste, subjects should safely be able to have five meal moments per day. This is a sensible and achievable dietary message for patients.

Non-sugar sweeteners: The intense sweeteners and xylitol are non-cariogenic while the other bulk sweeteners can be metabolized by plaque bacteria but the rate is so slow that these sweeteners can be considered safe for teeth. The use of nonsugar sweeteners is growing rapidly particularly in confectionery and soft drinks. Tooth-friendly sweets are available in many countries with Tooth-friendly (or Mr Happy-Tooth) logo. There is good evidence that sugarless chewing gums are not only non-cariogenic but also positively prevent dental caries, by stimulating salivary flow. Xylitol gums are used in school-based preventive programmes. Dietary advice for the prevention of dental caries: A dentist can make a diet diary for the child patient to give advices to prevent the caries risk. To give a dietary advice dentist have to learn following information. a. Number of intakes of food and drinks b. The number of intakes that contain sugars (excluding sugar in fruit) and how many were consumed between normal mealtimes c.

The term pit and fissure sealant is used to describe a material that is introduced into the occlusal pits and fissures of caries-susceptible teeth, thus forming a micromechanically-bonded, protective layer cutting access of caries-producing bacteria from their source of nutrients. Tooth surfaces with pits and fissures are particularly vulnerable to caries development observed that although the occlusal surfaces represented only 12.5% of the total surfaces of the permanent dentition, they accounted for almost ______% of the caries in school children.

Resin based fissure sealants (FS) are bonded to the underlying enamel by the use of the acid etch technique. Their caries preventive property is based on the establishment of a tight seal, which prevents leakage of nutrients to the microflora in the deeper parts of the fissure. The resin sealants may be pure resin, composites or compomers, and their polymerization may be initiated chemically or by light. Glass ionomer cements (GIC). One of the main clinical advantages of GIC is their ability to bond chemically to dentine and enamel without the use of the acid-etch technique which makes them less vulnerable to moisture. This, in conjunction with active F release into the surrounding enamel has led to the development and evaluation of GIC as an alternative FS system, particularly in cases where moisture control is difficult to achieve. Experiments have established that the F release in distilled water is very high during the first ______ hours (burst effect) and it drops rapidly during the following 48 hours before reaching a relatively constant level during the second week. This pattern of F release is common for all the conventional and resin modified GICs. The use of GIC has been suggested for erupting teeth where isolation is a problem, especially in the high caries risk individuals. In this situation they can be considered more a F vehicle than a traditional FS. Compomers. Compomers are currently being investigated widely in both in vitro and in vivo studies.

The need for surface cleaning and the method of cleaning pits and fissures prior to FS placement may seem to be controversial. Some studies suggest the careful removal of plaque and pellicle by the use of pumice or air-polishing instruments in order to obtain optimal acid-etch pattern of the enamel, while another maintains that the effect of acid etching alone is sufficient for surface cleaning provided obvious soft material has been removed. The literature is extensive on the efficiency of different cleaning procedures on bonding including the use of rotating burs in order to remove superficial enamel and open the fissure to have the resin penetrate into it. The early application technique for pit-and-fissure sealant application consisted of cleaning the enamel surface to be treated with pumice and water mixture using a rotary brush, either pointed or flat ended. Later many methods were introduced to clinical processes like air polishing, enameloplasty sealant technique, abrasion with alumina oxide and ______.

Adequate isolation is the most critical aspect of FS application. If the enamel porosity created by the etching procedure is filled by any kind of liquid, the formation of resin tags in the enamel is blocked or reduced, and the resin is poorly retained. Salivary contamination, during and after acid etching, also allows the precipitation of glycoproteins onto the enamel surface, greatly decreasing bond strength to the FS. The use of rubber dam is obviously the safest way of securing optimal moisture control, but in young and newly erupted teeth this is usually not practical, as it demands the use of local analgesia for placement of the clamp. Additionally, there is sufficient evidence that careful isolation with cotton rolls gives similar retention results. Etchants and conditioners. The goal of etching is to produce an uncontaminated, dry, frosted surface. The most frequently used etchant is orthophosphoric acid. In non-invasive FS applications 30 sec of etching is optimum time. In invasive FS applications 15 sec of etching is preferable. If the clinician is going to apply FS to primary tooth with non-invasive technique the etch time should be 60 sec, and at invasive 30 sec. Washing and drying. The tooth is usually irrigated vigorously with air and water for about 10 seconds and then dried with uncontaminated compressed air for 10 seconds. Both washing and drying are thorough enough to remove all etchant from the surface of the tooth to give a chalky, frosted ______.
