Toothbrushing—types and techniques
Design variations in toothbrush include the head size, length, diameter, and the modulus threads and their number, distribution, and angles. Operating effectiveness may be further depends on the humidity, temperature of the water and brushing technique. these variables to confound the comparison of numerous investigations to determine the optimal toothbrush features. Although the current opinion prefers the soft texture, nylon, multi-tufted brush with short head, there is no clear evidence that any one type of toothbrush surpass the others in relation to remove plaque and prevent gingivitis
. Frequent use of hard light brush was associated with gum recession.
Teeth cleaning methods
Teeth cleaning methods are classified according to the direction of cleaning stroke: (i) vertical; (ii) horizontal; (iii) roll technique; (iv) vibration methods (charters, Stillman, bass); (v) circular machinery; (vi) physiological techniques; (vii) brushes method.
Comparative study of these methods have yielded conflicting results, and each method has its own heroes. Bass technique is one of teeth cleaning methods are most commonly recommended dentists, hygienists. This involves placing the brush bristles at an angle of 45 degrees. the long axis of the teeth and vibrating brush anteroposterior direction to remove the plaque. Among the population in General, however, studies show that about one third of people use no specific cleaning stroke, and those who hire identifiable stroke, almost half of the roll method.
There is evidence that the power toothbrushes will improve the RAID management in specific patient groups: those with non-removable orthodontic appliances; children and adolescents; persons with physical or learning; and institutionalization of patients who depend on care providers to brush your teeth. It is difficult to tell whether the improvement RAID management by improving the efficiency of cleaning, or whether it will probably be short-term, and because of the?new the effect of cleaning with a new, more interesting product.
As a rule, nozzles electric toothbrushes, usually more compact than conventional, manual brush. Bunches of setae are located either in rows or in a pie chart, mounted in round head. Bristle also arranged as a more compact single brushes that facilitate removal of sediments of cleaning and cleaning in hard-to-reach areas of the mouth. Traditional design brush heads are working with the usual side to side, arched or reciprocating motion; considering that the circular brush heads are vibrational, rotational, or counter-rotational motions.
A number of new generation power toothbrushes also have new features that aim to further improve the treatment efficiency while reducing the likelihood of damage to the gums. Such features include:
- the current brush to facilitate plaque around the control of indigenous teeth;
- orthodontic head brush for cleaning around the components of orthodontic appliances;
- the rotating spiral or threads to improve clean removal of sediments;
- click mechanism to alert when a predetermined cleaning effect is achieved;
- timers, which usually indicate the cleaning time 2 min
Long established that brushing with normal toothpaste with fluoride is more effective from plaque control than brushing with water alone. This effect can be explained detergents, abrasive or antimicrobial effects of fluoride. Currently, in many toothpastes are formulated with a more effective antimicrobial agents that contribute significantly to ensuring the removal of plaque and reduce gingivitis
. Although the degree of abrasiveness cannot influence the amount of plaque removal is achieved, abrasive properties of toothpaste keeps film layer thin and prevents the accumulation of spots on the surface. Toothpaste with high dentin abrasion value can cause destructive lesions in the cervical area of the tooth, but the optimal degree of abrasiveness, which will reduce the film surface without damaging the tooth structure, is not defined. Some toothpastes now formulated, crystallization inhibitors, such as soluble pyrophosphates, zinc citrate, or polymer systems (Gantrez), which demonstrated decrease supragingival calculus formation...
