AbstractBackground: The non-communicable diseases dental caries and periodontal diseases pose an enormous burden on mankind. The dental biofilm is a major biological determinant common to the development of both diseases, and they share common risk factors and social determinants, important for their prevention and control. The remit of this working group was to review the current state of knowledge on epidemiology, socio-behavioural aspects as well as plaque control with regard to dental caries and periodontal diseases. Methods: Discussions were informed by three systematic reviews on (i) the global burden of dental caries and periodontitis; (ii) socio-behavioural aspects in the prevention and control of dental caries and periodontal diseases at an individual and population level; and (iii) mechanical and chemical plaque control in the simultaneous management of gingivitis and dental caries. This consensus report is based on the outcomes of these systematic reviews and on expert opinion of the participants.
The occlusal surfaces of partly and fully erupted first right permanent molars were examined with respect to the occurrence and distribution of plaque and dental caries in a group of 57 six- to eight-year-old children. The children were classified into four groups ranging from one tooth partially erupted to full occlusion. Occlusal plaque was recorded at two levels of examination: (1) visible plaque and (2) detailed mapping by means of a plaque detector system. Dental caries was recorded after professional cleaning. The recording of plaque was repeated after 48 hr without oral hygiene. The findings showed a significant reduction in the easily detectable plaque in fully erupted teeth, compared with the three groups representing partly erupted teeth. The detailed mapping of plaque showed a clear pattern of preferential locations related to the macromorphology of the occlusal surfaces, and revealed reduction in the frequency of thick plaque accumulation in the fully erupted teeth. The proportion of active lesions was reduced in fully erupted teeth, and arrested lesions were mainly observed in the same group. This indicated that erupting teeth are more likely to develop dental caries, due to favorable conditions for plaque accumulation. Functional usage of teeth in addition to improved access for toothbrushing promoted arrestment of lesions initiated during eruption.
A 2-day workshop of ORCA and the IADR Cariology Research Group was organized to discuss and reach consensus on definitions of the most commonly used terms in cariology. The aims were to identify and to select the most commonly used terms of dental caries and dental caries management and to define them based on current concepts. Terms related to definition, diagnosis, risk assessment, and monitoring of dental caries were included. The Delphi process was used to establish terms to be considered using the nominal group method favored by consensus. Of 222 terms originally suggested by six cariologists from different countries, a total of 59 terms were reviewed after removing duplicates and unnecessary words. Sixteen experts in cariology took part in the process of reaching consensus about the definitions of the selected caries terms. Decisions were made following thorough “round table” discussions of each term and confirmed by secret electronic voting. Full agreement (100%) was reached on 17 terms, while the definitions of 6 terms were below the agreed 80% threshold of consensus. The suggested terminology is recommended for use in research, in public health, as well as in clinical practice.
The aim of the study was to describe the 3-yr results of a treatment program designed to control occlusal caries on the basis of intensive patient education and professional toothcleaning. The sample consisted of 56 children 6-8 yr old with their permanent right first molars in different stages of eruption. The results were compared with record data from 58 children of the same age who had received a traditional caries treatment program including fissure sealing (control group). After 1 yr a significant reduction of occlusal surfaces with visible plaque was noted in the study group as well as an increased proportion of arrested lesions. These results were maintained after 2 and 3 yr. Ten (9%) teeth were sealed and one filled during the study period. Examination of record data in the control group over a 3-yr period revealed that 76 (65%) first molars were sealed and 7 (6%) were filled. During the first year 1/3 of the children in the study group needed 5-6 recall visits, whereas in the following period all children were only seen 1-4 times. In contrast, 50% of the children in the control group needed 5-6 recalls in the 3rd yr. Our data indicate that professional care for erupting teeth on an individual basis has a long-term effect on occlusal surfaces as well. The alternative technique required less clinical time than the traditional application of sealants.
Our findings emphasize the importance of early detection of these oral conditions in order to permit effective and long-term planning, according to the child's individual requirements.
Management of the caries process on occlusal surfaces of permanent molars has proven a major challenge. The onset of caries on these surfaces takes place soon after their eruption, and the permanent first molars, followed by the second molars, remain the sites in the dentition which show the highest caries prevalence. This paper is structured in the form of questions and answers in which traditional concepts of caries susceptibility of occlusal surfaces are appraised and confronted with the current evidence. Then, research studies examining the role of biological determinants on the development and arrest of occlusal caries in young permanent teeth are discussed. Finally, the contribution of these studies in terms of developing the available scientific evidence and our understanding of the caries process on occlusal surfaces is analyzed. The current evidence does not support the concept that the early onset and high prevalence of occlusal caries in young permanent teeth are due to a particularly low inherent resistance of the occlusal surface or due to the presence of inaccessible fissure-like structures on these surfaces. Evidence is provided to show that the most influential biological determinants of the development and arrest of occlusal caries are thick plaque accumulation on the groove-fossa system and the stage of tooth eruption limiting mechanical oral function. Consequently, active occlusal lesions are significantly more prevalent in erupting than in fully erupted teeth. The major contribution of this review is to provide updated knowledge about the biological principles determining the development and arrest of caries on occlusal surfaces of erupting teeth.
The aim of this study was to evaluate a treatment program designed to control occlusal caries on the basis of intensive patient education and professional toothcleaning. The sample consisted of 56 6-8-yr-old children with their permanent right first molars in different stages of eruption. Data from the program were compared with previous data recorded in a similar sample of children. After 1 yr the majority of children in the study group had their permanent right first molars in full occlusion. A significant decrease of surfaces with easily detectable plaque and an increase of surfaces without plaque was observed. The proportion of arrested lesions increased and active enamel lesions decreased. Fissure sealing was only needed in two teeth in contrast to more than 2/3 of molars in a comparable sample of children. The program proved to be an efficient alternative to fissure sealing in preventing occlusal caries in erupting teeth.
