Caries and periodontitis are biofilm associated diseases with multifacto­rial causes (etiology). They are still among the most common diseases affecting the general population. A major factor in the development of oral disease is related to biofilm; this is why the efficient removal of biofilm, in addition to regular dental check-ups and nutritional guidance, plays a major role in the prevention of oral disease. The removal of biofilm is not just up to dental professionals [4], but rather, the principal responsibility of the patient through regular home-based oral hygiene [6].

Nevertheless, the quality of home-based plaque removal can be described as inadequate for large parts of the population. Many dental professionals recommend the “Modified Bass Technique” for the mechanical removal of plaque using the toothbrush. However, this technique is difficult to learn. In literature, for example, no evidence can be found indicating that this technique is superior to the “horizontal scrubbing technique” with respect to plaque removal [5, 19, 25]. When employing manual as well as electric toothbrushes, it is agreed that compliance with a system of brushing is more important than adherence to a particular technique [5]. The regular implementation of a certain brushing system prevents that teeth, or tooth surfaces, are not accounted for during home-based oral hygiene [20].

As early as 1948, Bass recommended a systematic approach for brushing teeth [3]. Especially because the oral surfaces of mandibular teeth often display more hard and soft deposits than other tooth surfaces and are evidently neglected during home-based oral hygiene [17], cleaning should begin with the inner tooth surfaces during tooth brushing [17, 18]. Yet, our observations [8, 9] together with the findings from other studies have shown that patients primarily clean the vestibular surfaces first [8, 12]. Van der Sluijs et al. (2018) could determine that, in terms of plaque reduction in young patients with periodontally healthy dentitions, there was no significant difference whether or not the patients cleaned the oral or vestibular surfaces first [23].

To date, there is no clear data in literature with respect to the duration and frequency of tooth brushing [2, 6]. However, a “twice-daily, two-minute” brushing is generally recommended. Studies have shown that brushing twice daily with fluoride-containing toothpaste has a higher caries-preventive effect and reduces caries incidence more than brushing once daily [6, 10, 13]. Additionally, it has been shown that more plaque removal occurs by increasing brushing duration and employing manual as well as electric toothbrushes [15, 24, 26]. It has been observed that tooth brushing for one and two minutes achieves an average plaque reduction of 27 % and 41 %, respectively [21].

The Department of Conservative Dentistry, Periodontology and Preventive Dentistry of the Hannover Medical School introduced the “IOCTIPlus” brushing system in 2007. However, based on clinical observations, this system was changed to “CIOTIPlus” in 2009. Using this system, the patient first brushes the chewing, followed by the inside and the outside surfaces of the teeth with a toothbrush. Afterwards, the tongue and the interdental spaces are cleaned with interdental hygiene tools. Following this cleaning procedure, the patient systematically brushes the tooth surfaces using circular/rotation movements again (“plus”) with the same (pea-sized) amount of fluoride-containing toothpaste (Fig. 1). This brushing system is not a “double” brushing in the literal sense because the entire cleaning process is not repeated in the same manner. By re- applying fluoride-containing toothpaste, the tooth surfaces are me­chanically cleaned once again on the one hand, while an additional fluo­ride dose is supplied on the other hand; indeed, the effect of fluoride is higher on clean, plaque-free tooth hard substance [11].

The individual steps of the brushing system and technique for dental and oral hygiene are explained in detail below:

Before beginning tooth cleaning, the patient should first rinse his/her mouth vigorously with water. This ensures that coarse, non-adherent food particles are already removed from the mouth. Patients also have very different saliva qualities. Thus, this step makes it easier for patients with very viscous saliva or dry mouth to brush their teeth afterwards.

In the first step, the patient spreads fluoride-containing toothpaste (fluoride content approx. 1450 ppm) on the chewing surfaces. These surfaces are cleaned simultaneously, as scrubbing (short back and forth movement) is explicitly permitted. The amount of toothpaste applied should be “pea-sized” (equivalent to at least 1 g toothpaste) [16]. The chewing surfaces are brushed before the inside surfaces because patients find it easier to begin brushing with the chewing surfaces, on the one hand, while on the other hand, the toothpaste at the same time gets distributed in the mouth as the chewing surfaces are brushed. Moreover, it has been shown that techniques and behav­iors learned in childhood are often carried over into adult life according to the field of behavioral science [22]. Thus, a health-related behav­ioral change is difficult to achieve in adults [1]. Children are taught the “COI system” (brushing sequence: first chewing, followed by the outside and inside surfaces) at an early age, which likewise begins with the brushing of the chewing surfaces; this is why it is perhaps easier for adult patients to implement the system recommended here later in life.

In the second step, the brushing of the tooth inside surfaces is performed. The “basic rule” is to brush “from red to white”. The patient performs brushing posteriorly either using vibratory (analogous to the “modified Bass Technique”) or small circular movements (analogous to the “Fones technique”). However the “Bass Technique” is difficult for patients to learn, and not every toothbrush is suitable for the application of this technique, we recommend the use of small circular movements for our patients. In the area of the ante­rior teeth, the head of the brush is held vertically and a wiping and small circular movement (short back and forth movement) is performed. Both other studies [17] as well as our own observations [8, 9] have shown that the oral areas of the mandibular posterior teeth are especially neglected. Thus, in the lower jaw, patients should begin by brushing the inside surfaces of teeth from the last tooth on one side and then continue systematically, tooth by tooth, until they reach the last tooth on the opposite side. Afterwards, the inside surfaces of the upper jaw are brushed in a similar manner. In order to achieve the best possible result, an individ­ualized, observation-based oral hygiene consultation should take place beforehand. By doing this, dental professionals can track patients’ dental and oral hygiene using their own oral hygiene products. “Problematic areas” can in this process be iden­tified and the patients can thereby be individually informed, motivated and instructed accordingly (iIMI).

In the third step, the outside surfaces are brushed. The basic rule “from red to white” applies here as well. The patient can either brush the tooth surfaces using vibratory motion based on the “modified Bass Technique” or use small circular movements based on the “Fones Technique”. Here too, small circular movements are preferred. The patient should begin to brush from the last tooth on one side of the lower jaw and then continue systematically, tooth by tooth, until the last tooth on the opposite side of the jaw is reached. Following this, the teeth of the upper jaw are brushed in the same manner.

After the smooth surfaces have been brushed, the tongue is cleaned in the fourth step. Depending on the amount of plaque and nature of the tongue surface, the patient can either use a special tongue cleaner/scraper or the same toothbrush. At least two (forward and backward) pulling strokes from dorsally to ventrally along the median sulcus and the lateral borders of the tongue can be employed to clean the tongue with a cleaner/scraper. With a toothbrush, the tongue can be brushed using three circular movements at the same area of tongue.

In the fifth step, interdental cleaning takes place at the end after the smooth surfaces and tongue have been cleaned. It should be clear to the patient that the cleaning of the interdental spaces must be carried out separately from brushing; it requires time and concentration as well as special hygiene tools. There exist various tools for cleaning the interdental spaces such as dental floss, interdental brushes, and Soft-Picks for example. Not every hygiene tool is suitable for all of the interdental spaces. Within a dentition, interdental spaces vary in terms of width and shape. This implies that for an effective cleaning of the interdental spaces to take place, hygiene tools should be individually selected; consideration should not only be given to shape and size of the proximal spaces and the periodontal state, but also to user skill and acceptance. The recommended interdental tools should be demonstrated by dental professionals for proper use. For example, both approximal surfaces should be cleaned with two up and down movements using dental floss. The floss should be then removed as a loop out of the approximal space. When the interdental brushes and soft picks should be employed, after their insertion into the approximal space, each approximal surface should be cleaned using two horizontal brushing movements (according to the “X-Technique”).

In a recent study, it was found that the cleaning of interdental spaces with dental floss before smooth surface brushing leads to more plaque reduction and fluoride concentration in the interdental spaces than when interdental cleaning was performed after the brushing of smooth surfaces [14]. Nevertheless, this aspect plays a rather minor role in the system described here. This is because another step ensues after the cleaning of the interdental spaces, whereby fluoridated toothpaste is once again applied, thus leading to a similar effect.

In the sixth and last step (usually in the evenings), in order to enhance the effect of fluoride and cleaning, the patient should again apply in circular/rotating movements a same amount (pea-sized) of fluo­ride-containing toothpaste evenly systematically (CIO) on all tooth surfaces using a toothbrush (about 1 minute). By applying fluoride-containing toothpaste once again, additional fluoride is supplied to teeth and the tooth surfaces are me­chanically cleaned again. After this procedure, by taking a sip of water, the patient should dilute the toothpaste-saliva mixture (foam) in order to distribute this mixture throughout the mouth for 30 seconds, especially interdentally, and then spit it out.

“COIPlus System” for children – What does the “plus” mean here?

Analogous to the system described above for adults, we recommend the “COIPlus System” for children (Fig. 2). Firstly, the fluoridated toothpaste (fluoride content depends on the age of the child) is applied on the chewing surfaces, whereby “scrubbing” is allowed in order to distribute the toothpaste in the oral cavity and at the same time to brush the chewing surfaces. The amount of toothpaste varies depending on the age of the child (e.g., rice grain, lentil, or pea size). Afterwards, the outside surfaces of the teeth are brushed; the child paints “circles on the outside surfaces”, corresponding to the “Fones technique”. Subsequently, the tooth inside surfaces are brushed with a wiping movement. “Plus” means that the parents make sure that the teeth are properly cleaned and re-brush the gums and teeth (chewing/outside/inside surfaces) with rotating movements and an age-appropriate amount of fluoridated toothpaste.

The goals of the “CIOTIPlus” and “COIPlus” systems are a more effective plaque reduction as well as improved fluoride supply to the tooth surface. The effectiveness of the CIOTIPlus system has already been proven in studies [7, 8]. Increased plaque removal on smooth and proximal surfaces in older patients with periodontally rehabilitated dentitions was attained using the CIOTIPlus system [8, 9]. Furthermore, in a long-term investigation on older patients it could be shown that root surface and crown margin caries formation could be minimized and periodontal conditions could be stabilized or improved through the use of this system in combination with efficient follow-up care after peri­odontal therapy [7]. The effectiveness of the CIOTIPlus system is shown in Figures 3 to 5 and Table 1 in relation to a patient’s case.

Conclusion

A significantly improved plaque control/reduction is achieved using the described systems “CIOTIPlus” and “COIPlus.” Yet, in order to recognize “problem areas” related to plaque control, and thus be able to successfully prevent caries and periodontal disease, it is absolutely necessary that each patient receives an initial individualized and observation-oriented dental and oral hygiene advice, together with information and instructions, as well as regular follow-up instructions and motivation.

Implementing a rigid time schedule for dental and oral hygiene is counterproductive. The generally recommended 2 minutes needed to carry out sufficient dental and oral hygiene is in most cases inadequate. Especially for patients with complete as well as those with periodontally compromised dentitions and extensive prosthetic restorations or other difficult dental situations (for example, crowding, fixed orthodontic appliances) more time is required. Rather than timing how long brushing should take place, we recommend that our patients perform oral and dental hygiene until all teeth, tooth surfaces, and tongue have been cleaned. Only in step 6 (plus), we advise our patients to brush for no longer than a minute. Moreover, we recommend that patients perform dental and oral hygiene twice daily. Since many patients are often under time pressure in the morning, dental and oral hygiene according to the system described above should be carried out particularly in the eve­ning.
