Tooth loss impairs mastication, deglutition and esthetics and affects systemic health through nutritional deficiency, weight loss, muscle weakness, delayed wound healing, and bone fragility. Approximately 90% of tooth loss is due to dental caries and periodontal disease. Accordingly, early treatment of dental caries is essential to maintaining quality of life. To date, the clinical diagnosis of dental caries has been based on each dentist’s subjective assessment, but this visual method lacks objectivity. To improve diagnostic ability, highly sensitive quantitative methods have been developed for the diagnosis and prevention of dental caries and are gradually becoming a mandatory item in modern dentistry. High-resolution Raman spectroscopy is a suitable tool for recognizing the subtle structural changes that occur in dental enamel in already developed or, more importantly, incipient dental caries. Raman analysis could soon emerge as a breakthrough in dentistry because of its high diagnostic sensitivity. In this study, we build upon our previous findings in a new analysis of dental caries using Raman spectroscopy imaging and discuss the possibility of using Raman photonic imaging in support of objective diagnostics in dentistry. Our findings support the Raman method of caries detection in comparison with other conventional or new approaches.

Abstract Background An association between childhood anthropometric measurements and dental caries is conflicting. The prevalence and severity of dental caries and its association with anthropometric and behavioural factors, were investigated among Finnish teenagers. Methods The study sample comprised 202 15–17-year-old participants in the Physical Activity and Nutrition in Children (PANIC) Study. Dental caries findings were recorded using International Caries Detection and Assessment System (ICDAS) criteria, including activity estimation; numbers of decayed teeth (DT) and decayed, missing and filled teeth (DMFT) were recorded. Body weight, height and waist circumference were measured and respective body mass index (BMI) was calculated. Body fat percentage was assessed by dual-energy X-ray absorptiometry. Health-related behaviours and consumption of food and drinks were assessed using questionnaires, and intake of nutrients using a 4-day food record. Results Mean DMFT for all the participants was 2.4 (SD = 2.9), DT 0.6 (SD = 1.3), and 36% had DMFT = 0. No difference between genders was observed. In bivariate analyses, use of sugar-sweetened beverages (SSB) three times or less per week and not having used snuff associated significantly, whereas higher carbohydrate intake (E%), toothbrushing less often than twice a day and higher caries experience at baseline almost significantly with DT > 0. In adjusted regression analyses, frequent use of SSB and higher carbohydrate intake increased the odds for DT > 0. Additionally, higher carbohydrate intake (E%) and infrequent tooth brushing significantly associated with a higher number of DT. Conclusion Caries prevalence is still low and similar in Finnish teenage girls and boys. Behavioural factors are, but anthropometric factors are not associated with dental caries.

Concept Study

Dental caries has been considered the heaviest worldwide oral health burden affecting a significant proportion of the population. To prevent dental caries, an appropriate and accurate early detection method is demanded. This proof-of-concept study aims to develop a two-stage computational system that can detect early occlusal caries from smartphone color images of unrestored extracted teeth according to modified International Caries Detection and Assessment System (ICDAS) criteria (3 classes: Code 0; Code 1-2; Code 3-6): in the first stage, carious lesion areas were identified and extracted from sound tooth regions. Then, five characteristic features of these areas were intendedly selected and calculated to be inputted into the classification stage, where five classifiers (Support Vector Machine, Random Forests, K-Nearest Neighbors, Gradient Boosted Tree, Logistic Regression) were evaluated to determine the best one among them. On a set of 587 smartphone images of extracted teeth, our system achieved accuracy, sensitivity, and specificity that were 87.39%, 89.88%, and 68.86% in the detection stage when compared to modified visual and image-based ICDAS criteria. For the classification stage, the Support Vector Machine model was recorded as the best model with accuracy, sensitivity, and specificity at 88.76%, 92.31%, and 85.21%. As the first step in developing the technology, our present findings confirm the feasibility of using smartphone color images to employ Artificial Intelligence algorithms in caries detection. To improve the performance of the proposed system, there is a need for further development in both in vitro and in vivo modeling. Besides that, an applicable system for accurately taking intra-oral images that can capture entire dental arches including the occlusal surfaces of premolars and molars also needs to be developed.

Abstract:An overview of terahertz (THz) development is presented in view of possible medical applications, including details of the current technologies which could be effectively used. Although no clinical THz technologies are currently in use, its principal applicability has been already demonstrated in skin cancer detection and treatment, dental caries detection and pharmaceutical screening. Fundamental limitations of THz studies are highlighted which have to be overcome before clinical applications can be realized.

Tooth Surfaces

Dental caries is a disease that usually begins very early in life and from which few people remain unaffected. However, because caries is associated with local etiologic vectors, it can be controlled. Altering the diet to render it less cariogenic and making tooth surfaces more resistant to acid attack through the use of fluoride are two potent mechanisms of prevention. Pediatricians are in a unique position to contribute to the dental health of their young patients because of the early age at which children are brought to their offices and because mothers are accustomed to accept their recommendations. The pediatrician's role in caries control includes diagnosis, referral, and preventive therapy. Early referral of children who appear dentally healthy as well as those in which there are obvious cavities in the teeth has been stressed. As part of a caries preventive program, a system of systemic fluoride supplementation has been outlined for those children who are not drinking optimally fluoridated water. In addition, food-caries relationships have been discussed and practical suggestions for reducing the cariogenicity of a child's diet have been made. Although toothbrushing is considered a traditional method of caries prevention, it has not been discussed in this article for two reasons. First, published evidence does not conclusively support the premise that toothbrushing per se significantly reduces dental caries. Second, the results of the general efforts of the dental profession to motivate patients to adopt either meticulous or frequent brushing habits have been poor. It would be unrealistic to expect the medical profession to initiate procedures that would significantly alter the behavior of their patients' toothbrushing habits. Toothbrushing in the young child, especially the preschooler, should be regarded as another method for providing topical fluoride to the teeth. Parents should be encouraged to brush their young children's teeth as soon as they erupt. A soft, child-size toothbrush should be employed with a scrubbing motion. An anticariogenic toothpaste§ that has proven effective in controlled clinical trials should be recommended by the pediatrician or his nurse. It is hoped that the mechanisms for influencing children's dental health that were discussed in this article can be incorporated with minimum effort into the normal routine of pediatricians' practices.

The Impact

Objective: Data on the association between body mass index (BMI) and dental caries in children with orofacial clefts are sparse. Therefore, studies on the impact of BMI on caries frequency in children with cleft lip and/or palate (CL/P) are of importance. The aim of the current study was to investigate the association between BMI and frequency of dental caries in children with and without CL/P. Height, weight, and BMI in children with CL/P were also compared to controls. Design: This study used a cross-sectional case-control design. Participants: One hundred and thirty-nine 5- and 10-year-old children with CL/P and 299 age-matched controls. Main Outcome Measures: Caries was recorded according to the International Caries Detection and Assessment System. Height and weight were recorded, and BMI was calculated as weight/height2. Results: There was no correlation between BMI and caries frequency. Weight, height, and BMI were significantly lower in all children with CL/P compared to controls. After adjustment for international adoption, only BMI was significantly lower in CL/P children compared to controls. Non-adopted children with CL/P were significantly heavier and longer than adopted children with CL/P. Conclusions: Five- and 10-year-old children with corrected CL/P seemed to have a lower BMI than controls, but there was no association between BMI and caries frequency. Internationally adopted children with CL/P were lighter and shorter than non-adopted CL/P children and controls.
