"Forty years of experimental research, clinical trials, and demonstration projects in different geographical and social settings have confirmed that effective removal of dental plaque is essential to dental and periodontal health throughout life. “ 1998 European Workshop on Mechanical Plaque Control

The dental profession relies on mechanical plaque control (i. e. , daily cleaning with a toothbrush and other oral hygiene aids) as the most dependable way of achieving oral health benefits for all dental patients including periodontal patients.

Some toothbrush manufacturers claim superiority of design for such things as minor modifications of bristle placement, length, or stiffness. These claims are primarily based on demonstrations of plaque removal that are shown to be statistically significantly superior to comparable toothbrushes in one or more clinical studies.

The type of brush is largely a matter of individual preference. However, there is common agreement that use of a hard toothbrush, vigorous horizontal brushing, and possibly use of very abrasive dentifrice may lead to cervical abrasions of teeth and recession of gingiva.

In terms of recommending a particular toothbrush, superiority of clinical significance has not been demonstrated for any one type of toothbrush. Ease of manipulation by the patient is an important factor in brush selection, as is the patient's perception that the brush works well. The effectiveness of and potential injury from different types of brushes depend to a great degree on how the brushes are used.

The American Dental Association has described the range of dimensions of acceptable brushes: a brushing surface 1 to 1. 25 inches (25. 4 to 31. 8 mm) long and 5/16 to 3/8 inch (7. 9 to 9. 5 mm) wide, 2 to 4 rows of bristles, and 5 to 12 tufts per row. 2 A toothbrush should be able to reach and efficiently clean most areas of the teeth.

Toothbrush design (European workshop on mechanical plaque control 1998) n n n A handle size appropriate to user age and dexterity A head size appropriate to the size of the patient’s mouth End-rounded nylon or polyester filaments no larger than 0. 225 mm in diameter Soft bristle configuration as defined by the acceptable international industry standards Bristle patterns that enhance plaque removal in the approximal spaces and along the gum line

Usually the smaller the better

Smallest heads(1. 5 cm): Infants Medium heads(2 cm): Young children Regular heads(2. 5 cm): Adolescents

Infants’ brushes have large handles which facilitate manual dexterity

Bruun etal 1998: Toothbrush design has more effect on interproximal plaque than the brushing technique

Diameters of commonly used bristles range from 0. 007 inch (0. 2 mm) for soft brushes to 0. 012 inch (0. 3 mm) for medium brushes and 0. 014 inch (0. 4 mm) for hard brushes.

prevention through supragingival plaque control still remains the mainstay of controlling gingivitis and therefore the occurrence or re-occurrence of periodontitis

The importance of oral hygiene to outcome and longterm success of therapy for periodontal disease is hampered by the often ineffectiveness of mechanical cleaning to specific sites using a toothbrush and the limited or lack of use of interdental cleaning by many individuals

many individuals remove only around half of the plaque from their teeth even when brushing for 2 minutes (de la Rosa 1979). Presumably this occurs because certain tooth surfaces receive little or no attention during the brushing cycle (Rugg-Gunn & Mac. Gregor 1978, Mac. Gregor & Rugg-Gunn 1979).

Taken with the microbial etiology of both gingivitis and periodontitis, this supports the concept of employing agents to control plaque which require minimal compliance and skill in their use. This is the concept that underlies chemical supragingival plaque control

The adjunctive use of chemicals would therefore appear a way of overcoming deficiencies in mechanical tooth cleaning habits as practiced by many individuals.

Ideal sites of action for chemicals which might influence plaque accumulation

At present most antiplaque agents are antimicrobial and prevent the bacterial proliferation phase of plaque development. Plaque formation could be controlled by antiadhesive or plaque removal agents, but these are not, as yet, available or safe for oral use. Alteration of bacterial plaque pathogenicity through chemical agents or bacterial modification would require a greater understanding of the bacterial etiology of gingivitis.

Many vehicles may be used to deliver antiplaque agents but most information relates to mouthrinses and toothpaste. Toothpaste appears the most practical and cost effective method for chemical plaque control for most individuals. In formulating antiplaque agents into toothpaste, potential inactivation by other ingredients must be considered. Minority groups, such as the handicapped, may benefit from other delivery systems.

Dentifrices are made up of abrasives such as silicon oxides, aluminum oxides, and granular polyvinyl chlorides; water; humectants; soap or detergent; flavoring and sweetening agents; therapeutic agents such as fluorides and pyrophosphates; and coloring agents and preservatives.

Chemical inhibitors of plaque and calculus incorporated in mouthwashes or dentifrices also play an important role in plaque control. Fluorides are essential for caries control. These products have been highly marketed and are commonly used as adjunctive agents to mechanical techniques.

Abrasives, commonly in the form of insoluble inorganic salts, make up 20% to 40% of a dentifrice. The proper use of a dentifrice can enhance the abrasive action of a toothbrush as much as 40 times. Tooth powders contain about 95% abrasives and are five times More abrasive than pastes. The abrasive quality of dentifrices affects enamel, but abrasion is more of a concern For patients with exposed roots because dentin is abraded 25 times faster and cementum 35 times faster enamel. This can lead to root surface abrasion and root sensitivity

Existing literature suggests that hard tissue damage from oral hygiene procedures is mainly due to abrasive dentifrices, whereas gingival lesions can be produced by the toothbrush alone

Abrasions are more prevalent on maxillary than on mandibular teeth and are found more frequently on the left than on the right half of the dental arch. This suggests that access and right- or left-handedness may also contribute to the abrasion.

Dentifrices that provide the effectiveness required for plaque control with a minimum of abrasion are preferable. There is considerable interest in improving dentifrices by using them as vehicles for chemotherapeutic agents to inhibit plaque, calculus, caries, or root hypersensitivity.

Abrasive : calcium carbonate, calcium pyrophosphate, aluminium silicate Anti bacterial agents: sodium lauryl sulphate, zink citrate trihydrate, triclosan, metal ions Anti caries agents: sodium monofluorophosphate, sodium fluoride, stannous fluoride Desensitizing agents: strotium salts, sodium flouride, formalin Filler and thickeners: sodium carboxymethyl cellulose Humectant: glycerine Detergent: sodium lauryl sulphate Flavoring agents: mint Coloring agent Sweetener: sodium saccharin

To achieve caries preventive effect, free fluoride ions must be available in the paste, not bound to the ingredients in the abrasive system. Correct amount of flouride=1000 -1100 ppm.

Tartar control toothpastes with the active ingredient pyrophosphate This ingredient interferes with crystal formation in calculus and does not affect the fluoride ion in the paste or increase tooth sensitivity. This type of dentifrice has reduced the formation of new supragingival calculus by 30% or more
