- OBJECTIVE: The aim of the study was to test the hypothesis that root-filled teeth are at a higher caries risk than non-root-filled teeth. MATERIALS AND METHODS: Two sub-samples from epidemiologically obtained data collected in 1983, 1993 and 2003 in the city of Jönköping, Sweden, were analysed. All the participants were examined clinically and radiographically and the type of filling and the presence or absence of caries were recorded. Sub-sample 1 comprised 832 individuals (9202 teeth) aged 20-70 years with at least eight premolars/molars. In sub-sample 2, 163 subjects (577 teeth) with only one or two decayed tooth surfaces and at least one tooth with full crown coverage were analysed. RESULTS: Logistic regression analysis found that root-filled teeth were predictive of recurrent caries when controlling for the type of restoration in sub-sample 1 (OR = 1.68; 1.41-2.0; CI 95%) and sub-sample 2 (OR = 2.20; 1.07-4.52; CI 95%). CONCLUSION: In support of the suggested hypothesis, the data revealed a significant association between root-filled teeth and recurrent caries.

- NTRODUCTION: The aim of the present investigation was to evaluate the caries susceptibility of endodontically versus nonendodontically treated teeth in relation to dental plaque-related factors. METHODS: Twenty patients with 2 endodontically treated teeth (ETT) each were examined regarding cariogenic microflora of proximal plaque, in situ plaque pH drop after a sucrose rinse (Stephan curve), and de novo plaque formation. Recurrent caries and the quality of the coronal fillings/crowns of these teeth were also evaluated. ETT were compared with contralateral, nonendodontically treated teeth (NETT). RESULTS: Irrespective to the type of restoration, Streptococcus mutans count, de novo plaque formation, and recurrent caries were higher on the surface of ETT compared with NETT (P < .05). Moreover, the initial (resting) pH in plaque was significantly lower (P < 0.05) in ETT. CONCLUSIONS: ETT showed an increased susceptibility to caries as a result of either alteration in their biological environment or inadequacy of the marginal fit of the dental restoration. Clinicians should be aware of this risk.

Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Objective. The aims of this thesis were to: 1) analyse caries-related factors shortly after orthodontic treatment, 2) demonstrate the usefulness of the Cariogram by presenting orthodontic patients with different caries-risk profiles, 3) compare two different toothpastes with different post brushing techniques using an in situ caries model with orthodontic bands, and 4) test the hypothesis that toothpaste slurry rinsing, combined with some other simple post-brushing advice (in this thesis called the “modified F toothpaste technique, MFTT“), would reduce the number of decayed and filled tooth surfaces (DFS) in a 2-year randomised clinical trial in orthodontic patients. Materials and Methods. In Study I, a total of 100 patients were divided into two groups (50 in each), based on their pre-bonding DFS. A high- (DFS ≥ 5) and a low- (DFS ≤ 2) caries group were created. In Study II, three cases were selected to present the three caries risk groups, i.e. high, medium and low. In Study III, 20 orthodontic patients were randomised into two groups: 1) a test group using 5,000 ppm F with no post-brushing water rinsing and 2) a control group using 1,450 ppm F with 3 times post-brushing water rinsing. On the upper first premolars, orthodontic stainless steel bands were applied, leaving 2-3 mm of space away from the exposed buccal surface in order to accumulate plaque and create an area for initial caries development. The teeth were extracted after 8 and 9 weeks and were then analysed using Quantitative Light-induced Fluorescence (QLF). Moreover, the oral F retention was studied using the two brushing techniques. The Study IV population consisted of 100 orthodontic patients randomly divided into two groups. Each patient was examined before the beginning of orthodontic treatment (baseline) and shortly after de- bonding (follow-up) within a 2-year study period. The test group patients were instructed to use the MFTT, in which various behavioural factors were standardised in order to improve the caries preventive effect of F toothpaste. The control group patients were given the routine clinic oral hygiene instructions. Results. In Study I, the low-caries group displayed lower DFS (p < 0.001), lactobacilli (p < 0.001) and mutans streptococci (p < 0.001) and higher Cariogram values (p < 0.001). Study II showed that the Cariogram was a useful tool for distinguishing between low, medium and high caries risk patients. In Study III, in comparison to the control group, the test group regimen resulted in a non- significant smaller QLF lesion area and lower average QLF loss of fluorescence (p < 0.05). The highest F concentration under the band was found in the test group (p < 0.001). In Study IV, the clinical (p < 0.001), radiographic (p < 0.001) and clinical + radiographic (p < 0.001) ΔDFS (incidences) were significantly reduced in the test group in comparison to the controls, with prevented fractions of 87%, 78% and 83% respectively. Conclusions. 1) Patients with high DFS before orthodontic treatment ran a higher risk of developing caries. They had significantly higher numbers of mutans streptococci and lactobacilli and had less chance of avoiding new cavities according to the Cariogram. 2) The Cariogram may be a useful pedagogic model for illustrating a patient’s caries risk in the orthodontic clinic. 3) The combination of using a 5,000 ppm F toothpaste and no post-brushing water rinsing had better anti-caries potential and resulted in elevated oral F retention, compared with a 1,450 ppm F toothpaste with 3 times post-brushing water rinsing. 4) Compared with routine oral hygiene instructions including F toothpaste, the use of the MFTT significantly reduces the incidence of new caries lesions in orthodontic patients.

- This article describes the usefulness of Cariogram software in three orthodontic patients with high-, medium-, and low-risk caries profiles. Caries-related indicators and information needed for the Cariogram model were registered. The prebonding decayed and filled surfaces (DFS) indices for patient 1 (15-year-old girl) and patient 2 (18-year-old woman) were > 5, while in patient 3 (15-year-old boy), the DFS index was < 2. The data were entered into the interactive Cariogram software, which shows the various caries-related indicators. Patients 1, 2, and 3 had 6%, 58%, and 87%, respectively, actual chance of avoiding new caries. Patient 1 had high lactobacilli and medium mutans streptococci scores and a high caries risk. Patient 2 had a high DFS index and low buffer capacity, resulting in a medium caries risk. Patient 3 had low mutans streptococci and high lactobacilli scores and a low DFS index, resulting in a low caries risk. The Cariogram is available free online and is a useful educational model to illustrate a patient's caries risk. World J Orthod 2010;11:160-167.

- Overweight and obesity are increasing as health problems at global level. Dental caries and obesity are both multifactorial diseases and are associated with dietary habits. The aim of the present study was to investigate the relationship between body weight status and caries prevalence in an unselected population followed from pre-school years to young adulthood. The present investigation was designed as a longitudinal analysis of the association between overweight/obesity and dental caries in one population at 3, 6, 15 and 20 years of age. The result shows that adolescents (15 years) and young adults (20 years) who are overweight/obese had a statistically significantly higher caries prevalence than normal-weight young people. At 6 years of age, the odds (OR) of having caries among obese children are 2.5 times higher than the odds for caries among six-year-old children of normal weight (p = 0.04). At 3 years of age, no association between overweight/obesity and caries was found. To conclude, overweight and obese adolescents and young adults had more caries than normal-weight individuals. The present study emphasises the need for multidisciplinary approaches to change the lifestyle factors causing both overweight/obesity and dental caries.

- Objective: To analyse the relationship between caries determinants in early childhood and caries prevalence in proximal surfaces in adolescents at the age of 15 years. Methods: The present longitudinal study is part of a series of surveys of oral health in 671 children followed from 1 to 15 years of age. Data were selected from examinations, interviews and questionnaires at 1, 3 and 6 years and bitewing radiographs at 15 years of age. Uni- and multivariable logistic regression analyses were performed to identify caries-related determinants. The outcome variable was carious lesions and fillings (DFa) in approximal tooth surfaces at 15 years of age. Statistical comparisons were made between caries-free teenagers, DFa = 0 and teenagers with DFa > 0, DFa 4 and DFa 8, respectively. Results: In the final logistic regression analyses, caries experience at 6 years and mother's self-estimation of her oral health care as being less good to poor remained statistically significant and were related to caries in all three caries groups (i.e. DF > 0, 4 and 8) at 15 years of age. The consumption of sweets at 1 year remained statistically significant, with a caries experience of DF 4 and 8. The variables 'parents born abroad' and female gender were statistically significantly associated with DFa 4 and DFa 8, respectively. Furthermore, infrequent toothbrushing habits at 3 years of age and failure to attend the examination at 1 year were statistically significantly associated with caries at 15 years in the univariable analyses. Conclusion: Early caries experience, consumption of sweets at an early age and mother's self-estimation of her oral health care as being less good to poor are associated with approximal caries in adolescents. The study indicates that caries determinants identified during early childhood have a strong impact on approximal caries in adolescence.

- Abstract Objectives: To analyze various caries-related factors in orthodontic patients at de-bonding, and to test the null hypothesis that there is no difference in caries risk between governmental and private orthodontic patients immediately after orthodontic treatment. Materials and Methods: A cross-sectional examination was carried out on 89 orthodontic patients aged 13-29years, mean age 21.5years. They were divided into two groups based on the center of treatment, governmental group (G) (n = 45) and private group (P) (n = 44). The investigation comprised a questionnaire, plaque scoring, caries examination, bitewing radiographs, salivary secretion rate, buffering capacity, and cariogenic microorganisms. Data were entered into the Cariogram PC program to illustrate caries risk profiles. Results: Findings revealed that "the chance of avoiding new cavities," according to the Cariogram, was high in the P-group and low in the G-group (61% and 28%, respectively) (P < .001). Decayed, missing, and filled surfaces (DMFS), plaque index, mutans streptococcus and lactobacillus counts, and salivary buffer capacity were significantly higher in the G-group compared with the P-group (P < .05). The total number of caries lesions at de-bonding in the G-group was more than two times higher than that in the P-group (150 vs 68) (P < .001). Conclusions: The "chance to avoid new cavities" in orthodontic patients at de-bonding was less in the governmental group compared with the private group, as illustrated by the Cariogram. The governmental group also had significantly less favorable values than the private group for most of the caries-related factors.
