RESUMO
Periodontal diseases pose a significant global health burden, requiring early detection and personalized treatment approaches. Traditional diagnostic approaches in periodontology often rely on a "one size fits all" approach, which may overlook the unique variations in disease progression and response to treatment among individuals. This narrative review explores the role of artificial intelligence (AI) and personalized diagnostics in periodontology, emphasizing the potential for tailored diagnostic strategies to enhance precision medicine in periodontal care. The review begins by elucidating the limitations of conventional diagnostic techniques. Subsequently, it delves into the application of AI models in analyzing diverse data sets, such as clinical records, imaging, and molecular information, and its role in periodontal training. Furthermore, the review also discusses the role of research community and policymakers in integrating personalized diagnostics in periodontal care. Challenges and ethical considerations associated with adopting AI-based personalized diagnostic tools are also explored, emphasizing the need for transparent algorithms, data safety and privacy, ongoing multidisciplinary collaboration, and patient involvement. In conclusion, this narrative review underscores the transformative potential of AI in advancing periodontal diagnostics toward a personalized paradigm, and their integration into clinical practice holds the promise of ushering in a new era of precision medicine for periodontal care.
RESUMO
OBJECTIVES: Clinical trials testing new devices require prior training on dummies to minimize the "learning curve" for patients. Dentists were trained using a novel water jet device for mechanical cleaning of dental implants and with a novel cold plasma device for surface functionalisation during a simulated open flap peri-implantitis therapy. The hypothesis was that there would be a learning curve for both devices. MATERIALS AND METHODS: 11 dentists instrumented 44 implants in a dummy-fixed jaw model. The effect of the water jet treatment was assessed as stain removal and the effect of cold plasma treatment as surface wettability. Both results were analysed using photographs. To improve treatment skills, each dentist treated four implants and checked the results immediately after the treatment as feedback. RESULTS: Water jet treatment significantly improved from the first to the second implant from 62.7% to 75.3% stain removal, with no further improvement up to the fourth implant. The wettability with cold plasma application reached immediately a high level at the first implant and was unchanged to the 4th implant (mean scores 2.7 out of 3). CONCLUSION: A moderate learning curve was found for handling of the water jet but none for handling of the cold plasma. CLINICAL RELEVANCE: Scientific rational for study: Two new devices were developed for peri-implantitis treatment (Dental water jet, cold plasma). Dentists were trained in the use of these devices prior to the trial to minimize learning effects. PRINCIPAL FINDINGS: Experienced dentists learn the handling of the water jet very rapidly and for cold plasma they do not need much training. PRACTICAL IMPLICATIONS: A clinical study is in process. When the planned clinical study will be finished, we will find out, if this dummy head exercise really minimised the learning curve for these devices.

BACKGROUND: We investigated the efficacy of two different cold atmospheric pressure jet plasma devices (CAP09 and CAPmed) and an air polishing device with glycine powder (AP) either applied as monotherapies or combined therapies (AP + CAP09; AP + CAPmed), in microbial biofilm removal from discs with anodised titanium surface. METHODS: Discs covered with 7-day-old microbial biofilm were treated either with CAP09, CAPmed, AP, AP + CAP09 or AP + CAPmed and compared with negative and positive controls. Biofilm removal was assessed with flourescence and electron microscopy immediately after treatment and after 5 days of reincubation of the treated discs. RESULTS: Treatment with CAP09 or CAPmed did not lead to an effective biofilm removal, whereas treatment with AP detached the complete biofilm, which however regrew to baseline magnitude after 5 days of reincubation. Both combination therapies (AP + CAP09 and AP + CAPmed) achieved a complete biofilm removal immediately after cleaning. However, biofilm regrew after 5 days on 50% of the discs treated with the combination therapy. CONCLUSION: AP treatment alone can remove gross biofilm immediately from anodised titanium surfaces. However, it did not impede regrowth after 5 days, because microorganisms were probably hidden in holes and troughs, from which they could regrow, and which were inaccessible to AP. The combination of AP and plasma treatment probably removed or inactivated microorganisms also from these hard to access spots. These results were independent of the choice of plasma device.

AIM: To determine the long-term effects of the use of powered tooth brush (PTB) in comparison to manual tooth brush (MTB) on periodontitis severity, coronal caries experience, and the number of missing teeth using in a population-based cohort study. MATERIALS AND METHODS: Using 7-year follow-up data of 2214 participants of the Study of Health in Pomerania (SHIP-TREND), comprehensively adjusted linear models using generalized least squares and ordinal regression models estimated the effects of PTB usage on dental outcomes in complete case and imputed data. RESULTS: At follow-up, PTB users had lower medians for mean probing depth (PD; 2.21 mm) and mean clinical attachment levels (1.73 mm) than MTB users (2.30 and 1.96 mm, respectively). Adjusted models revealed the beneficial effects of PTB usage on follow-up levels of plaque, bleeding on probing, mean PD, percentage of sites with PDs ≥4 mm, mean clinical attachment levels (all, interdental, and non-interdental sites, respectively), and the number of missing teeth. For the number of missing teeth, the effects were more pronounced in participants aged ≥50 years. No significant effects of PTB usage on the number of decayed or filled surfaces (all and interdental sites) were found. CONCLUSIONS: A recommendation of PTB usage in dental practice could contribute to the long-term promotion of oral health.

OBJECTIVE: To conduct a systematic review of the published scientific evidence to evaluate the efficacy of nonsurgical periodontal therapy (NSPT) in treating periodontitis in patients with concurrent systemic conditions (diabetes, CVD, erectile dysfunction, chronic kidney disease, rheumatoid arthritis, polycystic ovarian syndrome, obesity, pregnancy). We hypothesised that NSPT results in better periodontal outcomes when compared to untreated controls after follow-up. MATERIALS AND METHODS: A systematic search (PUBMED/EMBASE) was conducted from 1995 to 2023 to identify randomised controlled trials (RCTs) with a minimum follow-up of 3 months. The primary outcome was the difference in mean probing depth (PD), and the secondary outcomes were mean clinical attachment loss (CAL), percentage of sites with PD ≤ 3 mm (%PD ≤ 3 mm) and percentage of sites with bleeding on probing (%BOP) between the treated and untreated control group in patients with comorbidities. RESULTS: The electronic search resulted in 2,403 hits. After removing duplicates, 1,565 titles and abstracts were screened according to the eligibility criteria, resulting in 126 articles for full-text screening. Following this, 44 studies were analysed. Restricting to studies with low bias or some concerns, NSPT group demonstrated a 0.55 mm lower mean PD (95%CI: -0.69; -0.41) after 3 months compared to the control group. CONCLUSION: Compared to the untreated controls, NSPT notably reduced mean PD, mean CAL, and %BOP while increasing %PD ≤ 3 mm in patients with concurrent systemic conditions. These findings suggest that NSPT is also an effective procedure in managing periodontitis in patients with concurrent systemic conditions. TRIAL REGISTRATION: This systematic review was registered under the protocol registration number CRD42021241517/PROSPERO.

Peri-implantitis-associated inflammation can lead to bone loss and implant failure. Current decontamination measures are ineffective due to the implants' complex geometry and rough surfaces providing niches for microbial biofilms. A modified water jet system (WaterJet) was combined with cold plasma technology (CAP) to achieve superior antimicrobial efficacy compared to cotton gauze treatment. Seven-day-old multi-species-contaminated titanium discs and implants were investigated as model systems. The efficacy of decontamination on implants was determined by rolling the implants over agar and determining colony-forming units supported by scanning electron microscopy image quantification of implant surface features. The inflammatory consequences of mono and combination treatments were investigated with peripheral blood mononuclear cell surface marker expression and chemokine and cytokine release profiles on titanium discs. In addition, titanium discs were assayed using fluorescence microscopy. Cotton gauze was inferior to WaterJet treatment according to all types of analysis. In combination with the antimicrobial effect of CAP, decontamination was improved accordingly. Mono and CAP-combined treatment on titanium surfaces alone did not unleash inflammation. Simultaneously, chemokine and cytokine release was dramatically reduced in samples that had benefited from additional antimicrobial effects through CAP. The combined treatment with WaterJet and CAP potently removed biofilm and disinfected rough titanium implant surfaces. At the same time, non-favorable rendering of the surface structure or its pro-inflammatory potential through CAP was not observed.

AIM: This study aimed to identify the factors influencing the changes in the number of teeth present and the number of healthy or filled surfaces between two time points. MATERIALS AND METHODS: Repeated cross-sectional data from population-based studies, namely the German Oral Health Studies (DMS-III vs. DMS-V), the Studies of Health in Pomerania (SHIP-START-0 vs. SHIP-TREND-0), and the Jönköping study (2003 vs. 2013), were analysed. Oaxaca decomposition models were constructed for the outcomes (number of teeth, number of healthy surfaces, and number of filled surfaces). RESULTS: The number of teeth increased between examinations (DMS: +2.26 [adults], +4.92 [seniors], SHIP: +1.67, Jönköping: +0.96). Improvements in education and dental awareness brought a positive change in all outcomes. An increase in powered toothbrushing and inter-dental cleaning had a great impact in DMS (adults: +0.25 tooth, +0.78 healthy surface, +0.38 filled surface; seniors: +1.19 teeth, 5.79 healthy surfaces, +0.48 filled surface). Inter-dental cleaning decreased by 4% between SHIP-START-0 and SHIP-TREND-0, which negatively affected the outcomes. CONCLUSIONS: From this study, it can be concluded that education may be the most important factor having a direct and indirect effect on the outcomes. However, for better oral health, powered toothbrushing and inter-dental cleaning should not be neglected.

BACKGROUND: Peri-implantitis therapy is a major problem in implantology. Because of challenging rough implant surface and implant geometry, microorganisms can hide and survive in implant microstructures and impede debridement. We developed a new water jet (WJ) device and a new cold atmospheric pressure plasma (CAP) device to overcome these problems and investigated aspects of efficacy in vitro and safety with the aim to create the prerequisites for a clinical pilot study with these medical devices. METHODS: We compared the efficiency of a single treatment with a WJ or curette and cotton swab (CC) without or with adjunctive use of CAP (WJ + CAP, CC + CAP) to remove biofilm in vitro from rough titanium discs. Treatment efficacy was evaluated by measuring turbidity up to 72 h for bacterial re-growth or spreading of osteoblast-like cells (MG-63) after 5 days with scanning electron microscopy. With respect to application safety, the WJ and CAP instruments were examined according to basic regulations for medical devices. RESULTS: After 96 h of incubation all WJ and CC treated disks were turbid but 67% of WJ + CAP and 46% CC + CAP treated specimens were still clear. The increase in turbidity after WJ treatment was delayed by about 20 h compared to CC treatment. In combination with CAP the cell coverage significantly increased to 82% (WJ + CAP) or 72% (CC + CAP), compared to single treatment 11% (WJ) or 10% (CC). CONCLUSION: The newly developed water jet device effectively removes biofilm from rough titanium surfaces in vitro and, in combination with the new CAP device, biologically acceptable surfaces allow osteoblasts to grow. WJ in combination with CAP leads to cleaner surfaces than the usage of curette and cotton swabs with or without subsequent plasma treatment. Our next step will be a clinical pilot study with these new devices to assess the clinical healing process.

BACKGROUND: Periodontitis is among the most common chronic diseases worldwide, and it is one of the main reasons for tooth loss. Comprehensive profiling of the metabolite content of the saliva can enable the identification of novel pathways associated with periodontitis and highlight non-invasive markers to facilitate time and cost-effective screening efforts for the presence of periodontitis and the prediction of tooth loss. METHODS: We first investigated cross-sectional associations of 13 oral health variables with saliva levels of 562 metabolites, measured by untargeted mass spectrometry among a sub-sample (n = 938) of the Study of Health in Pomerania (SHIP-2) using linear regression models adjusting for common confounders. We took forward any candidate metabolite associated with at least two oral variables, to test for an association with a 5-year tooth loss over and above baseline oral health status using negative binomial regression models. RESULTS: We identified 84 saliva metabolites that were associated with at least one oral variable cross-sectionally, for a subset of which we observed robust replication in an independent study. Out of 34 metabolites associated with more than two oral variables, baseline saliva levels of nine metabolites were positively associated with a 5-year tooth loss. Across all analyses, the metabolites 2-pyrrolidineacetic acid and butyrylputrescine were the most consistent candidate metabolites, likely reflecting oral dysbiosis. Other candidate metabolites likely reflected tissue destruction and cell proliferation. CONCLUSIONS: Untargeted metabolic profiling of saliva replicated metabolic signatures of periodontal status and revealed novel metabolites associated with periodontitis and future tooth loss.

OBJECTIVES: We aimed at investigating whether the interaction between the local inflammation, periodontitis, and obesity is independently associated with systemic inflammation. METHODS: From the population-based Study of Health in Pomerania, 3366 participants, without (2366) and with (1000) obesity, were studied for the association of periodontitis, measured as probing depth (PD) and plaque together with body mass index (BMI) on C-reactive protein (CRP). Quantile regression was used to evaluate the association between periodontal, anthropometric, and inflammatory variables (outcomes). RESULTS: The overall prevalence of obesity in this adult population was 31.4% in men and 28.1% in women. Both PD and plaque were positively associated with CRP, revealing an increasing impact across the CRP concentration distribution. Adjusting the regression of CRP or fibrinogen on PD for waist circumference attenuated but did not abolish the PD coefficients. Dental plaque was similarly associated with these interrelations. Association between PD and a dental plaque was different among participants with low-, medium-, or high-risk CRP concentrations. CONCLUSION: Local and systemic sources of inflammation contribute to blood levels of inflammatory markers. The respective contributions depend on the relative rate in each of the inflammation-inducing risks and are dominated by adiposity. CLINICAL RELEVANCE: Keeping systemic inflammation low in order to prevent age-related disease sequelae.

BACKGROUND: Currently, there is no comprehensive presentation of trends in oral diseases in the German general population over the last 20 years. OBJECTIVES: How did prevalences of caries, periodontitis, and tooth loss and their determinants change in Germany between 1997 and 2014? MATERIALS AND METHODS: We analysed data from 35- to 44-year-olds and 65- to 74-year-olds from the German Oral Health Studies ("Deutsche Mundgesundheitsstudien" [DMS]) III to V and of 25- to 74-year-olds from the Studies of Health in Pomerania (SHIP0 and SHIP-Trend-0). The decayed, missing, filled teeth index (DMFT), the number of sound teeth, the community periodontal index (CPI), and data on tooth count and edentulism were analysed. RESULTS: Regarding determinants, an increase in subjects with high school education, a slight decrease in smokers, and an increase in better oral hygiene patterns was observed in both studies. In 35- to 44-year-olds, the number of sound teeth increased from 11.9 in DMS III to 16.8 in DMS V, while in 65- to 74-year-olds the number of sound teeth increased by 5.9. A similar trend was observed in SHIP. In DMS, the prevalence of the highest CPI score of 4 decreased from 9.3% to 3.5% in 35- to 44-year-olds; in 65- to 74-year-olds, the 2014 prevalence was at the same level as in 1997 (10.5% and 9.8%). In parallel, the percentage of edentulous 65- to 74-year-olds halved in both studies. The number of teeth increased across all age strata. CONCLUSIONS: DMS and SHIP consistently showed an increase in the number of healthy teeth free of fillings, a slight reduction of subjects with a CPI score of 4, more tooth retention, and less edentulism. Because of more tooth retention and current demographic changes, higher periodontal treatment needs might be expected for the future.

OBJECTIVES: Although dental trauma and its unfavorable sequelae are considered major public health problems worldwide, the published data on the prevalence of traumatic crown injuries (TCIs) in Germany are lacking. Therefore, the present study assessed the prevalence of TCIs among adolescents in Bavaria, Germany. MATERIAL AND METHODS: Ethical approval and parental consents were obtained, and population-based information from 10- (N = 1158), 12- (N = 416), and 15-year-olds (N = 1302) from two different cohort studies performed in Bavaria (GINIplus/LISA and LAGZ) were examined for the presence of TCIs, dental caries, and restorations. Statistical comparisons were made using Mann-Whitney U test and Wilcoxon signed-rank test. RESULTS: The prevalence of TCIs was 6.3% in the 10- and 12-year-old children and 14.0% in 15-year-old children, and a higher prevalence was observed in boys than in girls. Most (87.5%) of the traumatized teeth were maxillary incisors. The caries prevalence was low in all three populations. CONCLUSION: The prevalence of TCIs in Bavarian adolescents at a low risk for caries was found to be low. CLINICAL RELEVANCE: Dental trauma is a prevalent event in children and adolescents, and incisors are the most affected teeth. Therefore, dental practitioners should be able to manage the spectrum of traumatic injuries.

OBJECTIVE: This study aimed to assess oral health-related quality of life (OHRQoL) in relation to associated covariates in orthodontic patients of different age groups (children, adolescents, and adults) in a cross-sectional study. METHODS: A total of 898 subjects (50.6% females, 49.4% males; mean age 16.89 years) undergoing orthodontic treatment anonymously completed the German version of the Oral Health Impact Profile (OHIP-G14) to assess OHRQoL in addition to completing 23 other items. Descriptive, exploratory statistical analysis and multiple linear regression modelling were performed. RESULTS: The mean score of the OHIP-G14 was 8.3 for the 6- to 11-year olds, 8.9 for the 12- to 17-year olds, and 12.6 for adults. Physical pain (Subscale 2) was the highest factor in all groups. Additionally, a relevant factor was Subscale 3 (psychological discomfort). A linear regression model showed that, in the adolescent group, aesthetics in combination with pain had a significant negative influence on OHRQoL, whereas, in the adult group, function in combination with pain showed the same significant negative influence. Second, except for the children, fixed appliances had a significant negative effect on OHRQoL compared to removable appliances. CONCLUSIONS: Our study showed that the majority of the 6- to 11-year olds and 12- to 17-year olds reported a good OHRQoL. Nevertheless, adolescents and adults who reported aesthetic/pain and function/pain problems, respectively, as reasons for orthodontic treatment showed a significant occurrence for reduced OHRQoL. Fixed appliances, in comparison with removable appliances, also resulted in a significant reduction in OHRQoL for both groups.

BACKGROUND: Sugar-sweetened drinks (SSDs) are known to be cariogenic, but this association has not been well investigated in population-based repeated cross-sectional studies in recent years. Therefore, this study examined whether SSD intake is associated with higher caries experience in 10- and 15-year-olds. METHODS: The study sample included participants from the Munich study centre of two birth cohorts with data on non-cavitated caries lesions (NCCL/S), caries experience (DMF/S index), overall caries burden (DMF + NCCL/S) and SSD intake. In total, 915 and 996 children were included from the 10- and 15-year follow-ups, respectively. Intake (g/day) of SSDs, comprising cola, lemonade, ice-tea, sport/energy drinks, fruit squashes and nectars, was calculated from food frequency questionnaires. For analyses, the SSD intake was converted into portions (250 ml/day). Multiple logistic regression and prospective analysis models were performed to test associations between SSD intake and various definitions of caries, adjusting for sex, parental education, body mass index (BMI) categories, study cohort, plaque-affected sextants, mode of SSD consumption, energy content of SSDs, and total energy intake. RESULTS: The mean overall caries burden at 10 and 15 years of age was 1.81 (SD: 2.71) and 6.04 (SD: 8.13), respectively. The average consumption of SSDs at the 10- and 15-year follow-ups was 0.48 (SD: 0.85) and 0.83 (SD 1.40) portions/day, respectively. After adjusting for confounders, in 10-year-olds, SSD intake was significantly associated with higher caries experience based on the indices DMF/S (adjusted odds ratio: 1.29; 95% CI: 1.06-1.57), NCCL/S (1.24; 1.03-1.49) and DMF + NCCL/S (1.27; 1.05-1.55). At the 15-year follow-up, SSD consumption was significantly associated with increased DMF/S index (1.12; 1.01-1.25) only. Prospective model associating 10-year SSD intake with 15-year caries experience was not significant. CONCLUSIONS: SSD intake significantly increases the caries burden in 10-year-olds, with attenuated effects in 15-year-olds. To prevent caries, SSD consumption should be reduced, especially in children and adolescents.

AIMS: This study aimed to assess 11-year longitudinal effects of powered toothbrush on periodontal health, caries and tooth loss in an adult population. MATERIALS AND METHODS: Participants of Study of Health in Pomerania (SHIP) cohort with dental examinations and interview data at SHIP-1, SHIP-2 or SHIP-3 examinations were included. Mixed-effects linear regression models were constructed between the exposure (manual versus powered toothbrush) and outcome variables (periodontal status using mean probing depth (PD) and mean clinical attachment loss (CAL), caries status using DMFS and DFS scores, and tooth loss), adjusting for potential baseline covariates. RESULTS: Final baseline (SHIP-1) study sample comprised of 2,819 participants. Powered toothbrush users increased from 18.3% (SHIP-1) to 36.9% (SHIP-3); were younger; had significantly less mean PD [ß: -0.09 (95% CI: -0.16; -0.02)] and mean CAL [ß: -0.19 (95% CI: -0.32; -0.07)] progressions; and had 17.7% less DMFS progression and 19.5% more teeth retained than the manual toothbrushers. CONCLUSIONS: In the long-term, powered toothbrush seems to be effective in reducing mean PD and mean CAL progressions, besides increasing the number of teeth retained.

PURPOSE: This prospectively designed, non-validated in vivo diagnostic study compared the results of visual examination, digital bitewing (BW) radiography and near-infrared light transillumination ( NIR-LT, DIAGNOcam) on proximal caries detection in posterior teeth. METHODS: A total of 203 subjects (122 men:81 women; mean age, 23.0 years) were included. All subjects were visually examined according to the standards by the World Health Organization and the International Caries Detection and Assessment System. In addition, digital BW radiographs were performed. NIR-LT images were captured from all posterior teeth. All BWs and NIR-LT images were blindly evaluated for the presence of enamel caries lesions ( ECLs) and dentin caries lesions ( DCLs). No histological validation was performed due to the impossibility to investigate healthy surfaces and non-cavitated caries lesions invasively. The statistical analysis included both descriptive and exploratory data evaluations. RESULTS: The diagnostic outcome differed for each method. Compared with BW radiography ( 8.0 surfaces) and NIR-LT (10.5 surfaces), visual examination revealed the fewest caries-related findings (4.2 surfaces). BW radiography or NIR-LT detected either 86.2% or 89.6% of all ECLs/DCLs in posterior teeth alone. When combining visual examination with NIR-LT, 70.9% of all ECLs/DCLs were similarly detected; when visual examination and BW radiography were combined, this proportion was lower ( 52.6%). CLINICAL SIGNIFICANCE: This study confirmed that visual examination alone led to an underestimation of the caries burden on proximal sites in posterior teeth. The novel near-infrared light transillumination might be a useful additional caries detection and diagnostic method.

AIM: This study compared the diagnostic outcomes of visual inspection (VI), digital bitewing radiography (BWR), and near-infrared light transillumination (NIR-LT, DIAGNOcam, KaVo, Biberach, Germany) for occlusal caries detection and assessment of posterior teeth. PARTICIPANTS AND METHODS: This study included 203 patients (mean age 23.0 years). All individuals received a meticulous VI. Additionally, BWR and NIR-LT images were collected. All BWR and NIR-LT images were blindly evaluated for the presence of enamel caries lesions (ECLs) and dentin caries lesions (DCLs). The descriptive statistical analyses included calculation of frequencies, cross tabulations, and pairwise comparisons using Pearson chi-square tests. RESULTS: The majority of ECLs/DCLs were detected by VI in this low-risk adult population. The additional diagnostic outcomes in terms of ECLs/DCLs amounted to 5.0% (BWR) and 6.8% (NIR-LT). The combined usage of VI/NIR-LT or VI/BWR identified 95.7 and 94.4% of all ECLs/DCLs on occlusal surfaces, respectively. CONCLUSION: This comparative diagnostic study showed that VI detected the majority of occlusal caries lesions. Both additional methods showed limited benefits. Due to the valuable features of NIR-LT, i.e., X-ray freeness and clinical practicability, this method might be preferred over X-ray-based methods. Nevertheless, BWRs should be prescribed in clinical situations where insufficient fillings or multiple (deep) caries lesions are diagnosed or where there is a need to assess the caries extension in relation to the pulp. CLINICAL RELEVANCE: VI has to be understood as caries detection method of choice on occlusal surfaces in low-risk adult population which may help to avoid multiple diagnostic testing, overdiagnosis, and overtreatment.

OBJECTIVES: The aim of the present study was to evaluate the adaptation of a calcium silicate bioceramic (BC) sealer with either BC or conventional gutta-percha compared with that of AH Plus sealer in different root canal sections. MATERIALS AND METHODS: Seventy-two extracted mandibular premolars were divided randomly into six groups. After standardised chemomechanical preparation, four groups were obturated with the BC sealer and BC gutta-percha or conventional gutta-percha, and the other two groups were obturated with AH Plus sealer and conventional gutta-percha either in lateral compaction or in a single cone technique. Each root was sectioned into three sections. An impression was made from each section, and replicas were then made for scanning electron microscopy (SEM) analysis. Areas and interfacial gaps were identified using image analysis software. In addition to descriptive and explorative data analyses, linear regression analysis was performed. RESULTS: All specimens had measurable interfacial gaps. Significantly fewer gaps were found between conventional gutta-percha and sealer compared to those observed when using the BC gutta-percha (p < 0.001). However, minor interfacial gaps between sealer and dentin were observed with the BC sealer (p = 0.04). The technique of obturation in different root canal sections did not significantly affect the sealer adaptability. CONCLUSION: The type of gutta-percha as well as the sealer had a noticeable impact on the adaptability. CLINICAL RELEVANCE: Different obturation techniques will result in similar outcomes. However, within the limitations of the study, there seems to be no advantage in using the BC gutta-percha.

AIM: This cross-sectional study was repeated at two time points and investigated the influence of gingivitis, smoking and body mass index (BMI) on the systemic inflammatory markers high-sensitivity C-reactive protein (hs-CRP) and interleukin 6 (IL6) in 10- and 15-year-olds. MATERIALS AND METHODS: The study sample of two birth cohorts, i.e. GINIplus and LISAplus, from the Munich centre consisted of 806 and 846 subjects who were evaluated at 10- and 15-year follow-ups respectively. Children and their parents completed questionnaires on participant-related lifestyle information. Gingivitis was measured at the sextant level using a simplified sulcus-bleeding index. Serum hs-CRP and IL6 levels were obtained from blood samples. Multiple logistic regressions adjusting for lifestyle-related factors and other confounders were performed to assess associations between the specified variables. RESULTS: There were no associations between gingivitis and the inflammatory markers hs-CRP and IL6 in 10-year-olds. In 15-year-olds, gingivitis (aOR: 2.17; 95% CI: 1.25-3.77); daily smoking (aOR: 6.27; 95% CI: 1.39-28.39); and being overweight/obese (aOR: 4.95; 95% CI: 0.73-33.68) were identified as significantly influencing factors for elevated hs-CRP values. Oral hygiene did not influence hs-CRP. CONCLUSION: In this study, hs-CRP was positively associated with gingivitis, smoking daily and overweight/obesity among 15-year-olds.

OBJECTIVES: Data on dental treatment of children with special healthcare needs (CSHCN) are sparse. Hence, this study provides information about the changes in the dental condition in a cohort of CSHCN treated in a university dental department in Germany. MATERIAL AND METHODS: Patient records of CSHCN treated from January 2004 to December 2012 were screened retrospectively for medical diagnoses (ICD-10) and the type of treatment performed with outpatient dental care (ODC) or general anesthesia (GA). Follow-up data of patients adhering to the recommended recall were recorded, including time and further treatments. RESULTS: A total of 795 CSHCN with a mean age of 6.8 years were included. In 41.6 % (331/795) of cases, treatment was performed under ODC, and 58.4 % (464/795) received GA. Caries experience in CSHCN treated under GA was significantly higher (7.9 d3/4mft/0.9 D3/4MFT) than in ODC (2.5 d3/4mft /0.9 D3/4MFT). Over time, patient flow shifted from invasive (IC) to preventive-based care (PC). CONCLUSION: Caries-related treatments were most frequent under GA and ODC, though initial caries experience was higher in GA patients. The choice of GA or ODC was statistically independent from the medical condition. CLINICAL SIGNIFICANCE: This study provides characteristics of a large population of CSHCN treated with and without GA for dental care.
