Delivery of Low-Diluted Toothpaste during Brushing Improves Enamel Acid Resistance. MATERIALS (BASEL, SWITZERLAND) 2023; 16:5089. [PMID: 37512363 PMCID: PMC10383383 DOI: 10.3390/ma16145089] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 06/28/2023] [Revised: 07/14/2023] [Accepted: 07/18/2023] [Indexed: 07/30/2023]
Abstract
Toothpaste viscosity decreases rapidly when diluted with saliva during brushing, potentially causing premature washout of high-risk caries areas and reducing the uptake of dental fluoride ions. However, no reports have examined the acid resistance of enamel from the perspective of the toothpaste's physical properties. This study aimed to elucidate the impact of toothpaste dilution on the acid resistance of the enamel, using bovine enamel as the subject. Five diluted toothpaste groups were created: a control group without toothpaste, and 100% (1.00×), 67% (1.50×), 50% (2.00×), and 25% (4.00×) dilution groups. Acid resistance was evaluated through pH cycling after toothpaste application. The results revealed a significant increase in substantial defects, compared to 67% (1.50×) at dilutions of 50% (2.00×) or higher, accompanied by a decrease in Vickers hardness. Moreover, the mineral loss increased with dilution, and a significant difference was observed between 67% (1.50×) and 50% (2.00×) (p < 0.01). This study revealed that the acid resistance of the enamel decreased when the dilution of toothpaste during brushing exceeded 67% (1.5×). Therefore, delivering toothpaste with a lower dilution to high-risk caries areas, including interproximal spaces and adjacent surfaces, could maintain a higher concentration of active ingredients in the toothpaste, thereby enhancing its medical effects.

Comparison of interproximal delivery and flow characteristics by dentifrice dilution and application of prepared toothpaste delivery technique. PLoS One 2022; 17:e0276227. [PMID: 36251665 PMCID: PMC9576051 DOI: 10.1371/journal.pone.0276227] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/19/2022] [Accepted: 10/03/2022] [Indexed: 11/28/2022] Open
Abstract
In home care, the toothpaste technique, which can enhance the caries-preventive effect without changing the amount of dentifrice and fluoride ion concentration, is of great significance. This study aimed to construct a model and experimental system that reproduces the interdental part and to clarify the relationship between the change in dentifrice viscosity due to dilution and washout in the high-risk approximal area of caries. Additionally, the effectiveness of the toothpaste technique and appropriate devices for delivering dentifrice to the interdental area at a low dilution were investigated. Diluted toothpaste samples were prepared (: ×1.00, ×1.25, ×1.50, ×1.75, ×2.00, ×3.00, and ×4.00). An acrylic interproximal model was created for this experiment. The flow characteristics and viscosity by dentifrice dilution were measured. In the case of low dilution of 57% (1.75×) or more, it was shown that the dentifrice in the high-risk area may be washed out early because of the decrease in viscosity, and the caries-preventive effect may be reduced. It was also suggested that to keep the dentifrice in the interdental area for 120 s at the end of brushing, a dilution must be devised to a concentration of at least 50% (2.00×). The prepared toothpaste delivery (PTD) method of delivering dentifrice to the interdental area while maintaining it at a low dilution is an effective toothpaste technique in terms of dentifrice dilution and viscosity. The use of finger brushes in the PTD method could increase the efficiency of dentifrice delivery.

Risk factors for and prevention of caries and dental erosion in children and adolescents with asthma. J Dent Sci 2022; 17:1387-1400. [PMID: 35784121 PMCID: PMC9236939 DOI: 10.1016/j.jds.2022.03.007] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/19/2022] [Revised: 03/16/2022] [Indexed: 11/07/2022] Open
Abstract
There are many studies and reviews of the relationship between the asthma disease in young individuals on the one hand and caries and dental erosion on the other. The causes of caries and dental erosion might be related to the asthmatic drugs, low pH and the sweeteners that the inhaled drug contains and perhaps even the lifestyle of children and adolescents with asthma. The main focus of this review is therefore to describe various preventive strategies, based on long experience of preventive dental care in Sweden. Two fact boxes are presented, one on fluoride toothpaste as a population-based intervention for different ages and one on diet counselling in children and adolescents with asthma. The most important thing is to introduce fluoride toothpaste early in the child's life and that the parents brush the child's teeth twice a day, in the morning after breakfast and at night before bedtime, up to the age of 10. Moreover, a high-risk approach with an additional fluoride supply at home is presented, together with the application of fluoride varnish at the clinic. Regarding diet counselling, it is important to make sure that the child has regular meals during the day, maximum five to six times a day, to allow the teeth to rest between meals and restrict sweets and soft drinks to once a week. It is important to identify children and adolescents with asthma as early as possible and to refer them to a dental team for preventive treatment.

Abstract
OBJECTIVE The health hazards of tobacco products depend on the level of exposure, but little is known about the characteristics of snus use. The aim of this study was to investigate the duration of daily exposure to snus among occasional and daily users and its associated predictive factors among young Finnish men. DESIGN Cross-sectional questionnaire study. SETTING Three out of 16 Finnish Defence Forces units. PARTICIPANTS 1280 young Finnish male conscripts starting their military service in 2016 chosen by simple random sampling. PRIMARY AND SECONDARY MEASURES The prevalence, duration of use and the amount of daily usage of snus and cigarettes were investigated. The attitudes towards perceived harmfulness of snus and the predictive factors affecting the total time of snus consumption were examined. RESULTS Almost a fifth (19.5%) of the conscripts reported daily snus use, and a further 16% reported occasional use. Daily snus use was associated with an earlier starting age, longer duration of use and higher daily exposure time compared with occasional use. On average, daily snus users consumed 10 portions and occasional users three portions per day (p<0.001). The daily total exposure time for daily users was 372 min (95% CI 344 to 401) and for occasional users 139 min (95% CI 106 to 171). Respondents with an upper secondary education had significantly less daily total exposure than those with basic comprehensive education (p=0.036). Perceptions of snus as a harmful substance resulted in a significantly lower duration of exposure. CONCLUSION Snus use was very common among young Finnish men. High snus exposure duration was associated with an earlier starting age, a longer history of use and a careless attitude to its health hazards. A higher education level was a protective factor for total exposure time. Studies of the long-term health effects and dependency profile of snus use are needed.

Abstract
Background The aim of this cross-sectional study was to compare the dimensions of mandibular symphysis (MS) between gender and the different sagittal and vertical skeletal relationships. Material and Methods Pre-treatment records of orthodontic patients were divided according to gender, sagittal (Class I, II and III) and vertical (decreased, average and increased mandibular plane [MP] angle) skeletal relationships. Measurements of MS parameters were performed on lateral cephalograms using IMAGEJ software. Comparisons between MS parameters and gender and the different skeletal relationships was performed using multifactorial and one-way ANOVA, and independent sample t-tests. Results A total of 104 records (25 males and 79 females) fulfilled the inclusion criteria. Males had significantly greater MS surface area, dentoalveolar length, skeletal symphysis length, total symphysis length, vertical symphysis dimension and symphysis convexity (p < 0.05). Skeletal Class II patients had significantly greater dentoalveolar and skeletal symphysis lengths while Class III had greater chin length, vertical symphysis dimension and symphysis convexity (p < 0.05). Patients with decreased vertical dimension had greater skeletal symphysis length (p = 0.026) and those with an average vertical relationship had greater chin length (p < 0.001). Conclusions The morphology of the mandibular symphysis is affected by gender, sagittal and vertical skeletal patterns. Males had increased mandibular symphysis surface area and linear dimensions. Class II patients had greater dentoalveolar length. Chin length was greater in patients with an average MP angle.

Abstract
OBJECTIVE To compare salivary fluoride (F) concentration and F retention after rinsing with a new 0.32% sodium fluoride (NaF) rinse and conventional 0.05 and 0.2% NaF rinses. METHODS Seventeen subjects (aged 22-26 years), with normal salivary secretion rates, participated in a double blind, cross-over study. In three separate sessions with a minimum washout period of 48 h, they rinsed for 1 min with 10 ml of 0.05, 0.2 or 0.32% NaF mouthrinse. Unstimulated whole saliva was collected before (baseline: 0 min) and after 1, 3, 5, 10, 20, 30, 45 and 60 min. The F concentration was plotted against time, and the area under the curve (AUC) calculated. Salivary F concentration and F retention for the three mouthrinses were compared by a randomized block test, followed by Tukey's test and a paired 2-tailed test. RESULTS There was a clear dose-response for AUC 3-60 min; 0.32% > 0.2% > 0.05% (p < .05). The mean F retention was 0.25 mg for 0.05% NaF, 0.86 mg F for 0.2% Na and 1.31 mg F for 0.32% NaF, (p < .05). CONCLUSIONS The higher salivary F concentration over time and the higher F retention after rinsing with an 0.32% NaF solution suggests a potential application in prevention of caries and dental erosion.

Abstract
Objectives The applied orthodontic force causes remodeling of the periodontium through the selective release of cytokines causing resorption of bone, enabling controlled movement of the tooth. This study compared the cytokine profile between patients treated with conventional labial and lingual fixed orthodontic appliances. Patients and Methods The study included 80 patients in need of orthodontic treatment, out of which 40 patients were treated by the labial fixed appliance and 40 by the lingual fixed appliance. Gingival crevicular fluid (GCF) specimens were gathered from both the groups using a microcapillary pipette. The samples were collected at the beginning of the treatment and after 21 days. Enzyme-linked immunosorbent assay was performed to evaluate the cytokine levels. Results Interleukin (IL)-1α, 1β, 2, 8, and tumor necrosis factor-alpha (TNF-α) levels were significantly high (P < 0.001) in GCF of participants treated with conventional labial fixed appliance. IL-1α, 1β, 2, 6, 8, and TNF-α levels were significantly high (P < 0.001) in GCF of participants treated by the lingual fixed appliance. The concentrations of TNF-α and IL-1β were increased higher than other cytokines in both the treatment groups. Conclusion Overall, the lingual fixed appliance had higher cytokine levels than a labial fixed appliance. Analyzing the GCF cytokine levels during orthodontic treatment could provide an ideal platform for monitoring the progress of the treatment.

Abstract
Background The role of saliva composition and dietary sugar in development of infundibular caries in equine cheek teeth is not fully understood. This study analysed electrolyte and urea concentrations in saliva in relation to different forage and measured pH changes after sucrose application in vivo in sound and carious cheek teeth. Results Forage type had no effect on the equine saliva electrolyte concentrations, which varied considerably both intra- and inter-individually. Chewing resulted in increased values for all electrolytes except bicarbonate. Compared with stimulated human saliva, horse saliva after mastication, contained higher amounts of potassium, calcium and bicarbonate, and less phosphate. The in vivo pH measurements showed a lower resting pH and a more pronounced pH drop after sucrose application in carious teeth compared to sound teeth. Conclusions No large differences were found between the composition of equine saliva and human saliva. A more pronounced acidogenicity was found for the carious than sound teeth. Thus, the caries process in equine cheek teeth seems to follow the same pattern as in human teeth, caused by acid production by oral microorganisms after sugar consumption.

Abstract
Objective: The aim was to study prevalence of xerostomia, hyposalivation and quality of life among caries active younger adults.Materials and methods: A questionnaire regarding oral and general health, xerostomia and quality of life was mailed to 134 caries active (CA) and 40 caries inactive (CI) patients, 25-50 years of age (mean age 39.9 ± 6.2 years) treated at a Swedish Public Dental Service clinic, regarding oral and general health, xerostomia and quality of life. Caries data and unstimulated whole salivary flow rates were obtained from dental records.Results: The overall response rate was 69%. Dental records confirmed that CA patients had more decayed teeth over time than CI patients (p < .001). The CA group reported worse oral health (p < .001) and general health (p < .01), more xerostomia (p < .001) and lower salivary flow rate (p < .01) compared to CI patients. Xerostomia was inversely related to unstimulated whole salivary flow rates as well as to oral and general health (p < .01). There were no differences between groups in quality of life.Conclusion: Younger caries active adult patients reported significantly more xerostomia and hyposalivation compared to caries inactive patients. Xerostomia and hyposalivation were inversely related to perceptions of oral and general health, but not to quality of life.

Abstract
Objective: The objective of this study was to compare the remineralizing effect of sodium fluoride (NaF) mouth rinse or NaF gel as an adjunct to NaF dentifrice on incipient caries-like lesions in an in situ cross-over design study, with three sessions of 30 days each. Materials and methods: Orthodontic brackets with artificial demineralized enamel slabs were attached to the upper first molars of 12 participants. A set of 3 test specimens from the same tooth was randomly assigned to each participant and allocated into three 30-day sessions: 1) brushing with 0.22% NaF dentifrice 2 times/day (F dentifrice), 2) brushing with 0.22% NaF dentifrice 2 times/day+ rinsing with 0.05% NaF before bedtime (F mouth rinse), 3) brushing with 0.22% NaF dentifrice 2 times/day + brushing with 1.1% NaF gel before bedtime (F brush-on gel). The mineral gain and lesion depth of the specimens were evaluated by micro-computed tomography. Results: The mean mineral gain from the NaF mouth rinse and the NaF brush-on gel was similar, but greater than that from the NaF dentifrice (p < .05). The NaF brush-on gel yielded the greatest mean depth of remineralization (168 µm), followed by the NaF mouth rinse (144 µm). Both depths were significantly greater than that of the NaF dentifrice (84 µm) (p < .05). Conclusions: Both 0.05% NaF mouth rinse and 1.1% NaF brush-on gel, used at bedtime, increased incipient caries-like lesion remineralization in situ in combination with brushing with NaF dentifrice twice a day.

Abstract
Objective: To test the hypothesis that the levels of IL-1ß and TNF-α increased more and IL-1α, IL-2, IL-6, IL-8 increased less, after 3 weeks of treatment with conventional labial fixed appliance and with aligners. Material and methods: Forty patients who were treated either with labial brackets (n = 20) or aligners (n = 20). Gingival crevicular fluid (GCF) samples were collected at baseline and after 21 days. Cytokine levels were evaluated by enzyme-linked immune sorbent assay (ELISA). Plaque index (PI), gingival index (GI), and bleeding on probing (POB) were also examined. Results: The levels of IL-1α, IL-1ß, IL-2, IL-6, IL-8 and TNF-α in the GCF were significantly increased in both groups. The levels of IL-2, IL-6, IL-8 increased more in patients treated with aligners compared to those treated by labial fixed appliances. There was a statistically significant difference in change of the mean cytokine levels of IL-1α, IL-2, IL-6, IL-8 and TNF-α compared to labial fixed appliances and aligners. Conclusions: The levels of the six studied cytokines in GCF (IL-1α, IL-1ß, IL-2, IL-6, IL-8 and TNF-α) increased after 3 weeks both after treatment with conventional labial fixed appliance and with aligners. IL-1ß and TNF-α showed a prominent increase compared to the other cytokines in the GCF of teeth by both the labial fixed appliance and aligners. However, there were only minor differences in the changes of the cytokine levels from baseline to 3 weeks between the two groups. There were no differences between the groups regarding PI, GI or POB.

Abstract
AIM The aim of this study is to investigate the caries situation in a group of Swedish adolescents, who were scheduled for orthodontic treatment with fixed appliances. MATERIALS AND METHODS An age- and gender-matched control group was selected from the same city (Malmö, Sweden). Caries and fillings on smooth surfaces and fillings on occlusal surfaces were diagnosed clinically and caries and fillings on approximal surfaces by bitewings. Numbers of mutans streptococci (MS) and lactobacilli (LB) were analyzed in saliva. RESULTS There were no significant differences regarding manifest caries lesions and fillings on smooth surfaces. Numbers of occlusal-filled surfaces (FS) and approximal decayed and filled surfaces were around 10%, but did not differ between the groups. However, 53% had approximal enamel caries lesions in the test group and 46% in the control group. The prevalence of approximal decayed surfaces (DS) and FS was low in both groups, 0.57 ± 1.41 in the test group and 0.65 ± 1.38 in the control group (p > 0.05), i.e., somewhat more DS in the control group (p < 0.05). Most individuals had low/medium counts of cariogenic bacteria in their saliva and less than 10% high counts in both groups. CONCLUSION Most Swedish adolescents who have been scheduled for treatment with fixed appliances appear to have a low-to-medium caries risk nowadays. However, around 10% of all approximal tooth surfaces of premolars/molars had enamel caries and one-third of the individuals had medium/high counts of cariogenic bacteria in their saliva, which may be risk factors for future caries during orthodontic treatment. CLINICAL SIGNIFICANCE Bitewing radiographs are important before starting orthodontic treatment and approximal caries and many cariogenic bacteria may be risk factors for orthodontic treatment.

Abstract
Objective: The aim of this study was to investigate how the Public Dental Service (PDS) in Sweden has managed to maintain a market position at a time of change in political ideologies and increased competition from a growing private sector. Materials and Methods: All Chief Dental Officers (CDOs), who had held this leading position for at least 5 years (n = 22), were asked to participate in a semi-structured telephone interview. Sixteen of the 22 CDOs participated in this study. The questions were sent by mail in 2014 before the telephone interviews, which were audiotaped, transcribed and analyzed using a qualitative analytical approach. Since this was a quality study with just few participants, no statistical analysis was carried out. Results: All the CDOs answered that they had influenced outcomes through brand building and core value work, related to both patients and employees, and to a lesser extent through competitor analysis. Some CDOs had a slightly different approach to the way they described visions, strategies and short-term goals. They used more business-oriented concepts, such as customers, market shares, and profits. Most CDOs regarded their actions as important for the successful development of their organization. Conclusions: The PDS appears to have a stable, strong position in the Swedish dental care market, and a great deal of effort has been put into consolidating this position.

Abstract
The number of children with Metabolic Syndrome (MetS) has recently been increasing in Japan. Few studies have investigated the relationship between MetS and oral health. The aim of this study was to investigate the association between MetS, lifestyle, and oral health status in school children. Our goal is to utilize these results in health education aimed at preventing the onset of MetS in school children and adults. A total of 689 Japanese children (365 boys and 324 girls) aged between 10 and 13 years were examined and waist circumference (WC), ratio of WC to height, blood pressure, fasting blood sugar (FBS), high density lipoprotein-cholesterol, and triglyceride values determined together with oral health status, including dental caries experience (DMFT). The results revealed that 6.5% of the children fell under the health board recognized "MetS or high risk of MetS" (MetS/HR) classification. A total of 140 (20%) children had a high Streptococcus mutans count. The mean WC, FBS, and DMFT values were significantly greater in children with a high salivary S. mutans count (p<0.05). Multiple logistic regression analysis revealed a statistically significance association between MetS/HR, non-breakfast eaters (odds ratio (OR): 2.70), no regular exercise (OR: 2.60), and a high salivary S. mutans count (≥10(5) CFU/ml; OR: 2.18; p<0.05). The present results indicate that lifestyle and salivary S. mutans count could be useful in screening children for MetS/HR. These variables may be useful in targeting interventions aimed at preventing MetS in school children.

OBJECTIVES To (1) analyze caries-related factors and (2) evaluate caries risk using the Cariogram model for governmental and private orthodontic patients at de-bonding and 4 years after de-bonding. MATERIALS AND METHODS Forty orthodontic patients with mean age of 26.4 years were recruited from a governmental (G) group (n = 20) and private (P) group (n = 20) and were examined at de-bonding (T1) and 4 years after de-bonding (T2). The examination included a questionnaire, plaque scoring, caries examination, bitewing radiographs, and assessment of salivary secretion rate, buffering capacity and cariogenic microorganisms. The data were entered into the Cariogram program to illustrate the caries risk profiles. RESULTS The chance to avoid new cavities was higher in P-group compared to G-group at T1 (58% and 31%, respectively) (P < 0.01) and T2 (77% and 52%, respectively) (P < 0.001). Plaque index was significantly higher in G-group, and fluoride was used significantly more in P-group at T1 and T2 (P < 0.05). The chance to avoid new cavities was higher at T2 compared to T1 (64% and 44%, respectively) (P < 0.001). Saliva secretion rate and buffer capacity were significantly increased, and the plaque index was significantly decreased at T2 compared to T1 (P < 0.01). CONCLUSION According to the Cariogram, orthodontic patients were less likely to avoid new cavities at de-bonding and 4 years after de-bonding in government clinics compared to private clinics, and the caries risk significantly decreased 4 years after orthodontic treatment for all patients, regardless of the location of treatment.

Abstract
OBJECTIVE The purpose of this study was to get new information from several sources about the background factors of Finnish smokers, snuffers, and dual users. Profiles of young smokers and snuffers were investigated in association with restorative treatment need, oral hygiene, eating habits, physical activity, body mass index (BMI), psychological and socioeconomic factors. MATERIAL AND METHODS The study group comprised 3420 conscripts. The data were collected from four different sources: a health examination including an oral health screening, a computer-based questionnaire for investigating individual background factors, a psychological test assessing cognitive skills, and the Cooper test. Statistical analyses comprised cross tabulation and binary logistic regression modelling. RESULTS The odds for smoking were the greatest among those who had DT (Decayed teeth) > 0, used energy drinks or alcohol regularly, or whose parents were divorced. A score of ≥2900 m in the Cooper test, a higher physical exercise level, a higher own education level, and using sports drinks decreased the odds for smoking. The odds for snuffing were higher among those who ran >2500 m in the Cooper test, had a BMI of ≥25, used sports/energy drinks, or exercised regularly, and lower among those who achieved good results in the cognitive test. Using energy/sports drinks or alcohol was positively and a higher education level was negatively associated with dual use. CONCLUSIONS Along with increasing prevalence of snuffing, heterogeneity is likely among snuffers. Good cognitive skills may prevent from smoking and snuffing.

Abstract
OBJECTIVE The aim of this study was to identify attitudes and behaviour relating to fluoride toothpaste and toothbrushing habits among caries-active Swedish adolescents. MATERIALS AND METHODS This cross-sectional study is based on an earlier clinical, two-year toothpaste intervention study. At the last appointment, 206 adolescents (of 211) answered a questionnaire comprising nine semi-closed questions. RESULTS The majority (93%) brushed their teeth every day, while 7% did so only occasionally. Most participants (77%) brushed twice a day, while 12% brushed just once a day. About half of those brushing just once a day forgot to brush in the evening. Similarly, more than half of the adolescents (53%) used 1 cm of toothpaste or less on their toothbrush. Moreover, 49% brushed for less than 2 min, 41% brushed for 2 min and 10% for more than 2 min. The majority (73%) rinsed with water after toothbrushing. A difference between boys and girls was also observed; 87% of the girls brushed twice a day, whereas only 67% of the boys did so and boys more frequently forgot in the evening. CONCLUSIONS Attitudes and behaviour relating to fluoride toothpaste and toothbrushing habits among caries-active Swedish adolescents are still inadequate after two years of toothpaste intervention. There are several areas where improvements can be made, such as frequency of brushing, brushing time, amount of toothpaste and post-brushing procedures. The majority (81%) included 'fresh breath' as a reason for performing oral hygiene and this aspect can be used by dental staff in health promotion.

Abstract
Background It has been suggested that dental caries should be regarded as a chronic disease as many individuals repeatedly develop new caries lesions. How this is perceived by caries active patients is unclear. The aim of this study was to measure patient-reported attitudes and negative experiences related to caries and dental treatment. Methods A questionnaire was mailed to 134 caries active (CA) and 40 caries inactive (CI) adult patients treated at a Swedish public dental service clinic. The questionnaire included items regarding patient-reported oral health; attitudes towards caries and efforts to prevent them; and negative experiences related to caries and dental treatment. Questionnaire data were supplemented with data on caries and caries prophylaxis from patients’ dental records. Exploratory factor analysis was conducted on items related to patients’ perceptions of problems to see whether scales could be created. Experiences, perceptions and dental records of CA and CI patients were compared. Results The overall response rate was 69%. Dental records confirmed that CA patients had significantly more decayed teeth per year and a longer period of caries-active time than CI patients. Factor analysis resulted in 3 distinct scales measuring problems related to caries; 1) caries-related information; 2) negative experiences; and 3) negative treatment/staff attitudes. A fourth scale measuring perceived problems related to caries was also created. The CA group reported significantly more problems related to caries and dental treatment, received significantly more caries-related information, and reported significantly more negative treatment experiences compared to CI patients. Conclusions Caries prophylaxis methods need to be improved in order to better meet the needs of caries active patients and to create a more positive experience with dental care.

Abstract
INTRODUCTION Dental caries and periodontal diseases are all induced by oral biofilm (dental plaque). This study was conducted to evaluate if fluoride-impregnated miswak is as effective in plaque removal and fluoride release as toothbrushing with fluoride toothpaste. MATERIALS AND METHODS This single-blind, randomized, crossover study was conducted at the Department of Cariology, University of Gothenburg, Gothenburg, Sweden, from February 2010 to January 2011. Fifteen healthy subjects participated in this study. The participants were instructed to use the following: (1) 0.5% NaF-impregnated miswak, (2) nonfluoridated miswak, (3) toothbrush with nonfluoride toothpaste, and (4) toothbrush with 1450 ppm fluoride toothpaste. Each method was used twice a day for 1 week after which plaque amount and fluoride concentration in resting saliva were measured. There was a 1-week washout period between each method. RESULTS No significant difference between miswak and tooth-brushing was found regarding plaque removal on buccal and lingual surfaces. A somewhat higher fluoride concentration in resting saliva was found after using impregnated miswak when compared with toothbrushing with fluoride toothpaste (p < 0.05). CONCLUSION Miswak and toothbrushing showed the same plaque removing effect on buccal and lingual surfaces. Miswak impregnated with 0.5% NaF resulted in a higher concentration of fluoride in saliva than brushing with 1450 ppm fluoride toothpaste. CLINICAL SIGNIFICANCE Miswak impregnated with 0.5% NaF and toothbrushing results in comparable plaque removal and about the same fluoride concentration in saliva even it was somewhat higher for impregnated miswak.

Abstract
OBJECTIVES This study was aimed to investigate the prevalence of maxillary lateral incisor agenesis and associated skeletal characteristics in an orthodontic patient population. MATERIALS AND METHODS The records of the 1066 patients seeking orthodontic treatment were screened for maxillary lateral incisor agenesis (MLIA). The following data were recorded for each subject: age; gender; unilateral or bilateral agenesis of MLI and side. The lateral cephalogram of each subject with MLIA was digitally traced. The data were compared to age-matched control orthodontic patients with skeletal Class I. RESULTS The prevalence of maxillary lateral incisor agenesis was 4.9% (52 patients) in which 63.5% were females. There was a significant difference between MLIA patients and controls in sagittal relationships (ANB, Wits, AB plane, angle of convexity and Co-A/Co-Gn differential analyses) p < 0.05. CONCLUSIONS Patients with maxillary lateral incisor agenesis showed a significant tendency for skeletal Class III compared with the Class I control. This could be attributed to maxillary hypoplasia/retrognathia.

Abstract
In many parts of Sweden today, school-based fluoride varnish programmes (FVP) are perfor- med by dental nurses. Studies have shown that the dental personnel are largely responsible for creating the atmosphere related to children's and adolescents'experiences of the program- mes. Knowledge of dental nurses'experiences of performing FVP is therefore crucial in order to develop and improve these programmes and the dental health of children and adolescents.The aim of this study was to describe dental nurses'experiences of performing FVP for children and adolescents in Sweden. Fifteen female dental nurses, strategically chosen, aged 40-63, from the Public Dental Service in the Vistra Gtaland Region, Sweden, were individually interviewed.The interviews were transcribed verbatim and analysed according to the phenomenographic ap- proach.Three themes with a total of 11 categories, all describing the dental nurses' conceptions of performing FVP, emerged in the analysis. The main conclusions were that in overall terms, performing an FVP was found to be a positive experience for the dental nurses, as it meant mee- ting children and adolescents in a context in which the children and adolescents are comforta- ble and relaxed.The opportunity to identify children and adolescents with poor dental health or poor health and to be able to offer them assistance was regarded as a major advantage. In addition,the participants described a feeling of professional development originatingfrom the challenges associated with working in an arena outside the dental clinic.

Abstract
The aim of this study was to measure patient-reported outcomes of caries prophylaxis and to compare them with previously documented efforts in dental offices. A questionnaire was mailed to 134 caries active (CA) and 40 caries inactive (CI) adult patients treated at a Swedish public dental service clinic. The overall response rate was 69%. The questionnaire included items regarding patient perceived caries prophylaxis in relation to: 1) treatment and recommendations given by the dental personnel, 2) performed self-care and 3) perceived and expected effects.The responses were studied for their association to clinical data, extracted retrospectively from the patients' dental records.The mean follow up time was > 16 years. Information about caries prophylaxis (p = 0.01) and recommendations for self-care (p = 0.04) were given more often to the CA group than to the CI group. Supplementary examinations and recommendations of self-care risk treatments were more frequent in the CA group (p < 0.001). CA patients also made more frequent extra efforts at home to avoid caries by changing their eating habits (p < 0.001), improving their oral hygiene (p = 0.04) and using extra fluoride (p = 0.001). In the CA group, 60% did not considerthat the extra prophylaxis efforts had made them caries inactive, and 40% were not satisfied with the outcome. Most patients (> 90%) hoped that the outcome of caries prophylactics would be a reduced number of cavities.The patient-perceived experiences of caries prophylaxis-were in concordance with dental records. Both the dentists and the caries active middle-aged Swedish adults were aware of the need for extra prophylaxis.The caries active patients perceived having made extra home care efforts, but had not experienced that they had become free from caries.

Abstract
PURPOSE To investigate the possibility of influencing adolescents' caries incidence, knowledge and attitudes to oral health and tobacco through a school-based oral health intervention programme. MATERIALS AND METHODS Four schools in a county in Sweden were randomised to one intervention and one control group. At the intervention schools, two dental hygienists worked 4 h every week for two years. Health education and preventive measures, such as fluoride varnish treatments every 6 months, were performed. The control group had no intervention. The study included a total of 534 participants aged 12-16 years. Outcome variables of the study were 1) caries incidence assessed on bite-wing radiographs and 2) knowledge and attitudes measured through questionnaires. RESULTS The intervention programme impacted on the incidence of enamel caries, while no effect on dentin caries could be seen. Data from the questionnaires showed that the adolescents considered their teeth as important. Adolescents in the intervention group had better knowledge about oral health and oral hygiene compared to the control group after the two years, but no impact on attitudes toward tobacco could be seen. A majority of the adolescents were positive to the education about oral health and tobacco and they believed that the dental hygienists would help them improve their oral health. CONCLUSIONS Although the effects of the intervention as regards to caries incidence, knowledge and attitudes were limited, the presence of dental hygienists in school was appreciated by the adolescents and seemed to increase their interest in their oral health.

Abstract
OBJECTIVE The aim of the study was to investigate the possibility of increasing knowledge about the caries-reducing effects of fluoride (F) toothpaste and to increase the use of F toothpaste among older adults through an intervention. MATERIALS AND METHODS 63-67-year-olds in Sweden, who 2 years earlier had answered a questionnaire about their knowledge of F toothpaste, toothbrushing and toothpaste habits and who had shown less favourable habits with regard to toothpaste use, were invited to participate. The 20-min intervention, performed at a Public Dental Clinic, was implemented by a dental hygienist (author OJ) and consisted of individual information and instruction on the use of F toothpaste. The questionnaire was repeated 4 months after the intervention and a population in another city in Sweden served as control. RESULTS In the intervention group, 68 individuals responded and 151 in the control group. Knowledge of the benefits of F toothpaste in the intervention group had improved between the times of the first and second questionnaires, but the same effect was also noted in the control group. After the intervention, a clear improvement concerning the use of F toothpaste was reported: the individuals brushed for a longer time, used more toothpaste and used less water during and after brushing. In the control group, there were no changes of habits between the first and second occasions. CONCLUSION Individually-based interventions performed by a dental hygienist had a positive effect on changing the way older adults used F toothpaste.

Dental caries and associated factors in a group of Swedish snus users. SWEDISH DENTAL JOURNAL 2015; 39:47-54. [PMID: 26529841] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Subscribe] [Scholar Register] [Indexed: 06/05/2023]
Abstract
The aim of this study was to investigate the effects of the Swedish moist powder tobacco product known as "snus" on dental caries and to measure the pH fall in dental plaque. The subjects comprised male and female adults between 26 and 62 years of age (n = 102), all habitual snus users for ≥ 10 years. The control group (n = 101) consisted of similar individuals in terms of gender, age and educational level but with no tobacco use for ≥ 10 years. A clinical and radiographic examination and a questionnaire were completed. The pH fall after a sucrose rinse was estimated in situ in 10 randomly selected subjects per group. The salivary secretion rate was higher in snus users than non-users (2.5 vs 2.2 ml/min, p = 0.005).There was no statistically significant difference regarding salivary buffer capacity. No differences were found between the two groups in terms of the plaque index, primary or secondary enamel and dentine caries, DFS and salivary counts of mutans streptococci or lactobacilli. The pH fall was somewhat more pronounced among non-users compared with snus users (NS). Snus users had a lower intake of snacks between meals and a less frequent intake of cookies (p = 0.000). Furthermore, snus users had a mean gingival index (± SD) for the whole dentition of 20.4 ± 18.2, while the index for non-users was 14.4 ± 13.9 (p = 0.09); the corresponding values for teeth 13-23 were 14.9 ± 20.6 and 7.7 ± 11.9 respectively (p = 0.003). To conclude, this clinical study revealed no statistically significant differences in caries prevalence between snus users and non-users and only minor differences regarding different caries associated factors.

Abstract
OBJECTIVE The aims of this study were (1) to evaluate the severity of buccal caries lesions according to the International Caries Detection and Assessment System (ICDAS) criteria via scoring buccal caries lesions on digital photographs at the time of de-bonding and (2) to compare this method with clinical examination. MATERIALS AND METHODS In total, 89 patients treated with upper and lower fixed appliances were clinically examined immediately after de-bonding by the first author and buccal caries were scored according to the ICDAS-II. Close-up digital photographs were taken of 245 teeth with different buccal caries lesion scores according to the ICDAS-II. Thirteen postgraduate orthodontics students independently scored the buccal caries lesions in the digital photographs using the modified clinical criteria (ICDAS-II). Intra- and inter-examiner reliabilities were evaluated by calculating the weighted kappa. To evaluate the validity of diagnosing the severity of buccal caries lesions using digital photographs compared to clinical examination, Spearman's correlation coefficient was calculated. RESULTS Intra-examiner reliability and the reliability between each examiner and the clinical examination showed moderate-to-excellent agreement, with kappa values of 0.52-0.83. Scoring buccal caries lesions via clinical examinations and scoring via photographs were well correlated according to the modified ICDAS-II criteria (Spearman's correlation coefficient, 0.76). CONCLUSIONS Thus, scoring buccal caries lesions on digital photographs according to ICDAS-II criteria is a reliable and valid method for assessing the severity of buccal caries lesions.

Abstract
OBJECTIVE To investigate the prevalence, distribution and severity of dental erosion and its association with lifestyle, oral and general health in young adults. MATERIALS AND METHODS Four hundred and ninety-four individuals, 20-years of age, participated. Dental erosion in molars and maxillary incisors was evaluated. Caries, plaque and gingivitis were registered. Saliva samples were taken and the subjects were interviewed about behavioural and dietary habits and oral and general health. Body mass index (BMI) was calculated. The individuals were sub-divided into two groups according to the presence and absence of dental erosion: within the group with erosion was a sub-group of individuals with extensive erosion. RESULTS Of the individuals 25% had no erosion, 75% had erosion and 18% had extensive erosion. Erosion was found in molars in 74% of the individuals and on buccal and palatal surfaces in maxillary incisors in 4% and 7%, respectively. Cupping was seen in 65% of individuals and severe erosion in molars in 1.6%. Compared to subjects with no erosion, those with extensive erosion had a higher consumption of soft drinks (p = 0.05), caries prevalence (p < 0.01), prevalence of mutans Streptococci (p < 0.01) and BMI (p < 0.05). Furthermore, subjects with erosion had higher caries prevalence (p < 0.01) and BMI (p < 0.01) than those with no erosion. CONCLUSIONS Swedish young adults have a high prevalence of dental erosion, but the level of severe erosion is low. The study disclosed a relationship between dental erosion and behavioural factors, oral health and BMI.

Abstract
The pH response of the dental biofilm after a sugar challenge can be considered to mirror the acidogenic potential and thereby the caries risk of an individual. The aim of this cross-sectional study was to evaluate the relationship between plaque pH and different caries variables in adolescents with varying caries prevalence. One hundred individuals, aged 14-15 years, were examined regarding different caries-related variables: (i) caries score (DSm, DSi, DSm + i, DTm), (ii) salivary secretion rate and buffer capacity, (iii) oral microflora of plaque and saliva, (iv) plaque amount, (v) plaque pH and (vi) dietary intake, oral hygiene habits and fluoride use. Plaque pH was assessed using the microtouch method before and after a 1-min mouthrinse with 10 ml 10% sucrose. Depending on the minimum pH, the participants were divided into three groups: low pH (≤5.3), medium pH (>5.3-6.3) and high pH (>6.3). Statistically significant differences between the three groups (p < 0.01) were found for initial caries (DSi) and combined manifest and initial caries (DSm + i). A statistically significant difference was also found in the log values for salivary lactobacilli (p = 0.02) within the three groups, and for the total number of bacteria in plaque (p = 0.04); for both variables, the low-pH group had the highest values. The only covariate significantly associated was the Cariogram score in the medium-pH group (p < 0.01) and the number of meals per day in the high-pH group (p = 0.02). To conclude, plaque pH measured by the microtouch method is a method that can be used for discriminating between individuals with varying caries prevalence.

OBJECTIVE To compare patients' perceived experiences of caries activity with recorded longitudinal caries prevalence, consequences of caries and length of recall intervals. MATERIALS AND METHODS A questionnaire was mailed to 134 caries active (CA) and 40 caries inactive (CI) adult patients at a Swedish Public Dental Clinic. The overall response rate was 69%. The questionnaire included items regarding perceived caries activity, general health, dietary and oral hygiene habits, level of education and socioeconomic status. Questionnaire responses were studied for their association to clinical data extracted from patient dental records. RESULTS There was a correlation between patient-perceived and documented caries activity for all respondents (rho = 0.65; p < 0.001). CA patients had significantly more perceived caries activity (p < 0.001), decayed teeth (p < 0.001), root fillings (p = 0.001) and extractions (p < 0.001) than CI patients. The mean recall interval was 1.5 years for CA and 2.1 years for CI (p < 0.001). In multiple logistic regression analysis, CA patients were at increased risk for xerostomia (OR = 22.66, p = 0.003), sleep disturbances (OR = 4.36, p = 0.04) and more frequent use of daily extra fluoride (OR = 3.58, p = 0.03). CONCLUSIONS Patient-perceived experience of caries correlated well with recorded caries activity in this group of middle-aged Swedish adults. Individuals with active caries were aware of their disease and made more frequent attempts to reduce caries activity by use of daily extra fluoride. Individual risk-based recall intervals did not seem to eliminate consequences of disease activity such as root fillings and extractions during the follow-up period.

Abstract
ABSTRACTObjectives:To clinically evaluate the prevalence of buccal caries and white spot lesions (WSLs) at debonding in governmental and private orthodontic patients, using the International Caries Detection and Assessment System (ICDAS-II) and the DIAGNOdent Pen, and to study the correlation between the two methods.Materials and Methods:A cross-sectional study was carried out on the nonextracted premolars and anterior teeth of 89 orthodontic patients. They were recruited into two groups based on the treatment center they attended: governmental group (G; n = 45) and private group (P; n = 44). Immediately after debonding, the examination of buccal caries and WSLs on premolars and anterior teeth was carried out using the ICDAS-II and the DIAGNOdent Pen. Cross-tabulation was applied to study the correlation between the ICDAS-II index and the DIAGNOdent Pen by calculating the Spearman correlation coefficient.Results:The G group showed a significantly higher (P < .0001) prevalence of WSLs and/or buccal caries compared to that of the P group based on evaluation by the two methods. Based on ICDAS-II, 43% of the patients in the P group and 9% in the G group were free from any WSLs. In the G group, 22% of the patients had ≥16 lesions, whereas there were none for the P group. The Spearman correlation coefficient between the two methods was .71.Conclusions:The prevalence of caries and/or WSLs at debonding was significantly higher in the G group compared to the P group. The clinical index (ICDAS-II) showed a good correlation with the DIAGNOdent Pen.

Abstract
AIM The aim of this study was to investigate oral rehydration therapy (ORT) products and their effect on plaque pH under normal and dry mouth conditions. DESIGN Three commercial oral rehydration therapy products, prepared according to the manufacturers' instruction, plus a 10% glucose solution, which served as control, were tested in 10 healthy subjects (mean age 25 years): (1) Electral (Arrow Pharmaceuticals), (2) Resorb Junior (Nestlé) and (3) Vätskeersättning (Semper). pH was measured in the maxillary premolar region in situ with the so-called microtouch method. The area under the pH curve was calculated. Their carbohydrate content was also analysed. RESULTS The oral rehydration therapy products gave the same low pH values in plaque as the glucose solution. Dry mouth condition, obtained by injection of methylscopolamine nitrate in the labial sulcus, resulted in an overall more pronounced fall in pH and in a delay in the pH recovery compared with normal salivary conditions. The chemical analyses showed that all three test-products contained glucose and starch as the main carbohydrates. CONCLUSIONS Rinsing with oral rehydration therapy products leads to a greater pH decrease in dental plaque during low compared with normal salivary conditions. As diarrhoea may result in dehydration and thereby in dry mouth, we believe that ORT products have a high cariogenic potential.

Abstract
OBJECTIVES To describe adolescents' experiences of participating in a school-based oral health intervention programme for 2 years containing education about oral health and fluoride varnish treatment at the school clinic. METHODS Sixteen adolescents aged 13-16 were interviewed in three focus group sessions. A phenomenographic approach was used for analysis. RESULTS The results are presented as three themes and seven descriptive categories. The three themes were 'Seeing the dental hygienist', 'Treatments at the dental hygiene clinic' and 'Education about oral health in class'. The results demonstrate satisfaction with the intervention, such as accessibility, time gain and expanding knowledge. On the other hand, feelings of vulnerability in the treatment sessions were expressed. The fluoride varnish treatment was given both positive and negative reviews. The contact between the participants and the dental hygienist was important, and the opportunity to ask questions about oral health issues was emphasized. CONCLUSIONS Both positive and negative experiences of the programme were found. Adolescence is a transitional period of life, and for this reason, it is important to create a good working alliance between students and the dental hygienist in future school-based oral health interventions.

Abstract
OBJECTIVE This study aims to assess clinical, microbiological and inflammatory parameters as indicators for caries and periodontal disease in adolescents with obesity. MATERIAL AND METHODS Twenty-seven adolescents with obesity [body mass index (BMI) 37 ± 4 kg/m(2)] and 28 controls (BMI 20 ± 2 kg/m(2)) answered questionnaires and were investigated regarding salivary parameters, plaque pH drop after a 1-min glucose rinse, oral clinical parameters, inflammatory markers in gingival crevicular fluid (GCF) and sub-gingival mirobiota. RESULTS Compared with controls, adolescents with obesity had a lower stimulated salivary secretion rate (1.55 ± 0.63 vs. 2.05 ± 1.05 mL/min, p < 0.05), higher concentrations of secretory immunoglobulin A (sIgA) (p < 0.001), more decayed tooth surfaces (3.4 ± 6.6 vs. 0.8 ± 1.1, p < 0.05) and more gingivitis (p < 0.01) after controlling for possible confounders. Overall, similar snacking habits, plaque amounts and numbers of deep periodontal pockets were observed. Following the glucose rinse, a slightly more pronounced drop in plaque pH was observed in the obesity group (p > 0.05). No differences in sub-gingival inflammatory or microbial indicators were detected (p > 0.01). CONCLUSIONS More caries and gingival inflammation were observed in adolescents with obesity. Of the indicators tested, salivary secretion rate was lower and sIgA levels were higher in the obesity group. We are unable to confirm whether differences in caries and gingival inflammation are due to systemic changes that are associated with obesity or due to possible irregular dietary/oral hygiene habits. CLINICAL RELEVANCE Customised oral health preventive programmes and appropriate collaboration with medical personnel in selecting the best diet, medication and psychological support can help improve the general well-being, including oral health, of children with obesity. This may even reduce the risk of oral diseases.

Abstract
OBJECTIVE The aim was to investigate fluoride (F) retention in plaque, saliva and pH drop in plaque using high-F toothpaste (5000 ppm F) or standard toothpaste (1450 ppm F) twice a day or 3-times a day. A method using the toothpaste as a 'lotion' and massaging the buccal surfaces with the fingertip was also evaluated. MATERIALS AND METHODS The investigation had a randomized, single-blinded, cross-over design and 16 subjects participated in six brushing regimes: (1) 5000 ppm F; twice a day, (2) 5000 ppm; 3-times/day, (3) 5000 ppm; twice a day, plus the 'massage' method once a day, (4) 1450 ppm F; twice a day, (5) 1450 ppm; 3-times/day and (6) 1450 ppm; twice a day, plus the 'massage' method once a day. The outcome measure was F retention in plaque, saliva and the plaque-pH change after a sucrose rinse. RESULTS The highest F concentration was found using high-F toothpaste (No 1-3) and differed significantly from those with 1450 ppm (No 4-6). Brushing with high-F toothpaste 3-times a day (No 2) resulted in a 3.6-times higher F saliva value compared with standard toothpaste twice a day (No 4) (p < 0.001). Increasing the frequency of application, from twice to 3-times a day, increased the F retention in plaque significantly when the two methods for application 3-times a day were pooled (p < 0.05). Brushing with 5000 and 1450 ppm toothpastes twice a day plus the 'massage' once a day resulted in the same F concentration in saliva and plaque as brushing 3-times a day with the same paste. CONCLUSION A third application of toothpaste is increasing the F retention and toothpaste as a 'lotion' and massaging the buccal surfaces with the fingertip may be a simple and inexpensive way of delivering F a third time during the day.

Abstract
OBJECTIVE The prevalence of caries and various risk factors was studied cross-sectionally in two cohorts of 72-year-olds over the course of 20 years. Incidence was also studied over a period of 6 years. MATERIAL AND METHODS Samples of two dentate subjects from cohorts of 70 to 72-year-olds were included; cohort III (n=135), born 1911-12, and cohort VI (n=139), born 1930. Cohort III was also examined at 70 years of age and re-examined after 6 years. An interview and clinical examination, including DMFS, plaque and gingival bleeding indices, pocket depth, and secretion rate for stimulated whole saliva, were carried out. RESULTS The mean numbers of teeth in cohorts III and VI were 14 and 21, respectively. On average, 2.1 tooth surfaces were decayed (DS) in cohort III compared with 1.3 in cohort VI (p<0.05). 49% of the individuals in cohort III did not develop any new DS, while 19% developed ≥3 DS during the 6-year follow-up period. The prevalence of caries was related to plaque and gingival bleeding indices, as well as a pocket depth of ≥4 mm, at ages 70 and 72. Moreover, the incidence of caries was related to the same factors. CONCLUSIONS The numbers of remaining teeth increased and the prevalence of caries decreased over the 20-year period. The incidence of caries over the follow-up period of 6 years was moderate. The results indicate that the prevalence of plaque, gingival bleeding, and a pocket depth of ≥4 mm are predictive factors for both prevalence and incidence of caries.

Abstract
OBJECTIVE The aim of this study was to evaluate some intra-oral caries-associated variables and tobacco use on dental caries. MATERIALS AND METHODS The participants were randomly recruited from three cross-sectional studies in Jönköping, Sweden, in 1983, 1993 and 2003. Each study consisted of 130 individuals in each of the 20, 30, 40, 50, 60 and 70-year age groups. Of these, 550, 552 and 523 dentate individuals attended respective year of examination. They were all examined both clinically and radiographically. A questionnaire was completed in conjunction with the examination. In the studies, 345 were smokers, 104 snus users and 1142 non-tobacco users, in total 1591 individuals. RESULTS In 1983 and 1993, there were no significant differences in mean DFS between non-users and smokers, but a statistically significantly higher mean DFS in comparison with snus users. In 2003, there was no statistically significant difference in mean DFS between the groups. Multiple regressions showed that, after adjusting for age, gender and socio-demographic variables, there was a statistically significant association between DFS and smoking in 1983 (smoking excluded in favour of lactobacilli when further analysed) and DFS and plaque index (PLI) in 1993. In 2003, there was no association, apart from buffer capacity (Power rising) between DFS and the examined intra-oral caries-associated variables and tobacco use. CONCLUSIONS The results of these epidemiological studies, performed in 1993 and 2003, indicate that daily smoking or snus use does not increase the risk of dental caries.

Abstract
BACKGROUND Psoriasis is a chronic inflammatory disease that is manifested on the skin. Studies of oral health in psoriasis patients are limited. The aim of this study is to assess the experience and risk of caries and periodontal disease in individuals with and without psoriasis. METHODS The material consisted of 89 individuals with mild-to-moderate chronic plaque psoriasis and 54 without psoriasis, recruited at the University Hospital in Gothenburg, Gothenburg, Sweden. Psoriatic arthritis (PsoA) was diagnosed in 25 of the individuals with psoriasis. All participants answered questionnaires and were subjected to saliva sampling and oral radiologic and clinical examinations. Two computer applications were used for illustration of oral disease risk profiles. RESULTS Individuals with psoriasis had lower salivary pH, fewer remaining teeth, fewer sites with probing depth ≤4 mm, and a lower radiographic alveolar bone level than individuals without psoriasis (P <0.05). Most of the differences remained significant after controlling for confounders. Differences in alveolar bone levels were no longer significant, particularly after introducing the confounder sex into the regression model. Similar numbers of decayed and filled teeth, sites with deep pockets, sites that bled on probing, and risk profiles were observed. Individuals with PsoA exhibited a lower stimulated salivary secretion rate than those without psoriasis (P <0.05). CONCLUSIONS There were no differences in profiles of caries and periodontal disease experience and risk between individuals with and without psoriasis. Fewer remaining teeth were observed in individuals with psoriasis. However, the exact reason for tooth loss could not be identified. Meanwhile, the reduced salivary pH in individuals with psoriasis and salivary secretion in individuals with PsoA may pose some risk for future caries.
