The macroscopic and microbiological impact of effective plaque control is the cornerstone for the short- and long-term success of our treatments. Getting our patients to perform effective and long-lasting plaque control requires progressive step-by-step training. Dentists themselves can inform and educate patients, but trained assistants can also do this. This needs time, but ten more seconds daily of effective brushing or interdental plaque control at home means one hour of treatment per year (3600 seconds) on the considered tooth surface. Patients need time to assimilate and use all these new concepts and practices. The dentist will define the aim of home treatment and explain it carefully to the patient, and to the assistant if available. This is easier if dentists and their teams are sensitive to people's ability to take ownership of the techniques taught. Time spent is not wasted, but has to be considered like an investment by both dental team and patient.

Professional Mechanical Tooth Cleaning (PMTC) is the cornerstone of active preventive office/consulting room treatments. Mechanical removal of dental plaque is vital for the prevention of carious and periodontal disease. Patients often see only the cosmetic improvement but dentists are primarily seeking a biological and bacteriological impact on all "at risk". PMTC aims to: Remove soft coatings on dental tissue, restorations, dental and implanted prostheses; Restore polish on surfaces, using suitable mechanical treatment; Create a surface that discourages subsequent bacterial recolonisation, and facilitates the flow of saliva over the tooth surfaces; Further the process by using chemical treatment to improve decontamination and remineralisation. Modifying the flora through mechanical disturbance, and the surfaces by polishing, PMTC fosters ion exchange on the tooth surface and creates a new bacterial balance. The frequency of application, the only variable, depends upon carious (or periodontal) risk. To be effective, PMTC should preferably be conducted on patients who have already shown good home plaque control, because this is the guarantee of long-lasting results.

Demineralisation and remineralisation are balanced processes that normally happen in the mouth. Sometimes, weak organization of tooth structures and alterations in diet, oral hygiene or bacterial activity can lead to the predominance of demineralising agents, resulting in initial lesion formation and tooth decay. Early diagnosis and the right approach can stop this progressive destruction and sometimes it is possible to repair and completely heal lesions. This applies to non-cavitated white spot lesions, where the right therapeutic protocols based on fluoride, calcium-phosphate and above all, CPP-ACP-based products, can really halt/reverse the caries process. The right approach is always based on the right interpretation of the pathological situation and on knowledge about how these commonly available bioactive products work.

In the process of treating caries, the first step is not only to identify risk factors and the presence of demineralised areas, but also to identify the best way of treating cavitated or non-cavitated lesions. If the lesions are cavitated we must be invasive, because we have to remove infected tooth tissue. However, there are different ways of treating non-cavitated lesions without removing surrounding sound structures. Fluoride and CPP-ACP have demonstrated in the past their strong capacity to promote remineralisation, with complete consequential healing of lesions. CPP-ACP, in particular, provides calcium and phosphates that are constituents of hydroxyapatite and, in combination with saliva and/or fluoride, can promote strong repairing actions. The respect of protocols is anyway fundamental to obtain the best results.

Because of the absence of any restorative material, which can fully replace the enamel and dentin, preservation of tooth structure should be of paramount importance in any treatment plan. Almost all of 20th century dentistry used the classification of cavities by Black, for the treatment of dental caries. So removing the diseased tissue of healthy tooth extensions was used to treat the injuries. New minimal intervention approaches display more respect for the dental structures, aiming to preserve tooth tissue and minimize treatment side effects as much as possible. Appropriate technology and tools continue to be developed. This article covers some currently available tools and methods for cavity preparation: manual removal, micro-preparation tools, micro-abrasion, sono-abrasion, laser and magnification.

This article describes how Minimum Intervention Dentistry has developed. Its techniques are less invasive than those of traditional dentistry. The glass-ionomer cements have undergone numerous changes and their clinical properties have improved. These high viscosity materials now constitute an excellent alternative to traditional restorative materials. Where the treatment of caries requires a biological approach and where the biocompatibility requires greater attention, the use of these materials is indicated.

Glass-ionomer cements have changed dramatically in recent years. The development of different chemical mixtures and the advent of nanotechnologies led industry to develop easy-to-use, strong and aesthetic products that started to be substitutes for other common materials, like amalgam. In particular, high viscosity glass-ionomer cements became a viable solution for reconstructions in posterior load-bearing areas but the higher wear and tendency to fracture, shown by many of GICs in comparison with other materials, limited their use in daily practice. However, the development of resin-based coating agents has resulted in better maturation of glass-ionomer cements and harder surfaces against wear and chipping of margins. In fact, the resin-based coating agents, once placed on the surface of a restoration, penetrate inside the porosities of glass-ionomers, creating a smooth surface, very resistant to occlusal forces and protecting margins from chipping and detachment. The Equia® system represents the most up-to-date glass-ionomer-based system, and its light-curable coating agent creates a strong and resistant protective layer.
