Analysis of Prosthetic Joint Infections Following Invasive Dental Procedures in England.

Importance: Dentists in the United States are under pressure from orthopedic surgeons and their patients with prosthetic joints to provide antibiotic prophylaxis before invasive dental procedures (IDP) to reduce the risk of late prosthetic joint infection (LPJI). This has been a common practice for decades, despite a lack of evidence for an association between IDP and LPJI, a lack of evidence of antibiotic prophylaxis efficacy, cost of providing antibiotic prophylaxis, and risk of both adverse drug reactions and the potential for promoting antibiotic resistance. Objective: To quantify any temporal association between IDP and subsequent LPJI. Design, Setting, and Participants: This cohort study used a case-crossover and time trend design to examine any potential association between IDP and LPJI. The population of England (55 million) was chosen because antibiotic prophylaxis has never been recommended to prevent LPJI in England, and any association between IDP and LPJI would therefore be fully exposed. All patients admitted to hospitals in England for LPJI from December 25, 2011, through March 31, 2017, and for whom dental records were available were included. Analyses were performed between May 2018 and June 2021. Exposures: Exposure to IDP. Main Outcomes and Measures: The main outcome was the incidence of IDP in the 3 months before LPJI hospital admission (case period) compared with the incidence in the 12 months before that (control period). Results: A total of 9427 LPJI hospital admissions with dental records (mean [SD] patient age, 67.8 [13.1] years) were identified, including 4897 (52.0%) men and 4529 (48.0%) women. Of these, 2385 (25.3%) had hip prosthetic joints, 3168 (33.6%) had knee prosthetic joints, 259 (2.8%) had other prosthetic joints, and 3615 (38.4%) had unknown prosthetic joint types. There was no significant temporal association between IDP and subsequent LPJI. Indeed, there was a lower incidence of IDP in the 3 months prior to LPJI (incidence rate ratio, 0.89; 95% CI, 0.82-0.96; P = .002). Conclusions and Relevance: These findings suggest that there is no rationale to administer antibiotic prophylaxis before IDP in patients with prosthetic joints.

A comparative study of propofol alone and propofol combined with midazolam for dental treatments in special needs patients.

ABSTRACT: Although dental treatment with sedation is performed increasingly in special needs patients, data on adding midazolam to intravenous propofol sedation are very limited for this group. The purpose of this study was to identify the factors and procedure time associated with the use of intravenous sedation with propofol alone or propofol combined with midazolam in dental patients with special needs.This was a retrospective data analysis. The sedation medications and relevant covariates, including demographic parameters, disability levels, oral health conditions, dental procedures, treatment time, and side effects, of 718 patients with special needs were collected between April 2013 and September 2014. The unfavorable side effects by sedation types were reported. Factors associated with procedure time and the sedation medications were assessed with multiple logistic regression analyses.Of 718 patients, 8 patients experienced unfavorable side effects (vomiting, sleepiness, or emotional disturbance) after the dental procedures; the rate was 0.6% in the 509 patients who received propofol only. In 209 patients who received propofol and midazolam, 2.4% experienced the side effects. Sedation time was associated with body mass index (BMI) < 25 (adjusted odds ratio [aOR] = 1.45, 95% confidence interval [CI]: 1.04-2.04) and the performance of multiple dental procedures (aOR = 1.44, 95% CI: 1.06-1.97) but not associated with the sedation types. A significant odds ratio for the combined use of propofol and midazolam was shown for adolescents (aOR = 2.22, 95% CI: 1.28-3.86), men (aOR = 2.05, 95% CI: 1.41-2.98), patients with cognitive impairment (aOR = 1.99, 95% CI: 1.21-3.29), and patients undergoing scaling procedures (aOR = 1.64, 95% CI: 1.13-2.39).With the acceptable side effects of the use of propofol alone and propofol combined with midazolam, multiple dental procedures increase the sedation time and the factors associated with the combined use of propofol and midazolam are younger age, male sex, recognition problems, and the type dental procedure in the dental treatment of patients with special needs.

Has the Health Insurance Coverage of Scaling Contributed Positively to Periodontal Health in Korea?

This study aimed to evaluate the effectiveness of the health insurance coverage of dental scaling (introduced in 2013) using the Community Periodontal Index of Treatment Needs parameter among Korean adults aged 20 years or older. We used the Korea National Health and Nutrition Examination Survey data from before and after 2013 to analyze the statistical significance and associations of the covariates with the prevalence of healthy periodontal tissues, prevalence of people in need of scaling, and prevalence of periodontal diseases. The results showed that the prevalence of healthy periodontal tissues increased by 4.9% (from 34.2% to 39.1%), the number of people in need of scaling decreased by 5% (from 65.9% to 60.9%), and the prevalence of periodontal diseases increased by 7.2% (from 23.4% to 30.6%). Moreover, after the scaling coverage policy, the odds ratio of the prevalence of healthy periodontal tissues was 1.10 times higher, the prevalence of the need for scaling was 1.5 times higher, and the prevalence of periodontal diseases was 0.90 times lower. Therefore, the state should formulate policies that provide dental biofilm management through a disclosing agent, impart education about oral hygiene, and develop a health management system that enables the concurrent management of periodontal diseases and systemic diseases.

How Root Caries Differs between Middle-aged People and the Elderly: Findings from the 4th National Oral Health Survey of China.

OBJECTIVE: To investigate the differences in distribution of root caries and related factors between middle-aged and elderly people in China. METHODS: In this cross-sectional study, a multistage, cluster strategy was used to recruit 4,410 participants (2,197 males and 2,213 females) aged 35 to 44 years and 4,431 participants (2,222 males and 2,209 females) aged 65 to 74 years from all 31 provinces, autonomous regions and municipalities of the mainland of China. The survey was conducted according to the basic methods proposed by the World Health Organization (WHO). Sociodemographic information, oral health behaviour, attitude and knowledge, history of dental prophylaxis and general health condition were collected with a closed questionnaire. RESULTS: A great increase in the occurrence of root caries in Chinese adults from 35 to 44-year-old to 65 to 74-year-olds, with the prevalence (DFR ≥ 1) from 25.4% to 61.9% and with the mean DFR score from 0.54 ± 1.34 to 2.63 ± 3.75. Filling rates were also very low, only 1.8% and 3.0%, respectively. Females and residents of rural areas were more likely to suffer from root caries. In both the middle-aged group and the elderly group, root caries related to gender, education level, sweet food/drinks consumption, oral health knowledge and status of root surface explosion. In 35 to 44 year olds, toothbrushing is a significant protection factor (OR = 0.88, 95%CI 0.81 ~ 0.96), while using toothpicks is a risk factor (OR = 1.06, 95%CI 1.02 ~ 1.10). In 65 to 74 year olds, not having dental had scaling in the past 12 months is a risk factor (OR = 1.66, 95%CI 1.09 ~ 2.53). CONCLUSION: Root caries among middle-aged people and elderly people in China have different risk factors and need more attention in future research to develop proper prevention.

Dental Scaling Decreases the Risk of Parkinson's Disease: A Nationwide Population-Based Nested Case-Control Study.

The protective effect of dental scaling in Parkinson's disease (PD) remains inconclusive. The aim of this study was to analyze the association between dental scaling and the development of PD. A retrospective nested case-control study was performed using the National Health Insurance Research Database of Taiwan. The authors identified 4765 patients with newly diagnosed PD from 2005 to 2013 and 19,060 individuals without PD by matching sex, age, and index year. In subgroup 1, with individuals aged 40⁻69 years, individuals without periodontal inflammatory disease (PID) showed a protective effect of dental scaling against PD development, especially for dental scaling over five consecutive years (adjusted odds ratio = 0.204, 95% CI = 0.047⁻0.886, p = 0.0399). In general, the protective effect of dental scaling showed greater benefit for individuals with PID than for those without PID, regardless of whether dental scaling was performed for five consecutive years. In subgroup 2, with patients aged ≥70 years, the discontinued (not five consecutive years) scaling showed increased risk of PD. This was the first study to show that patients without PID who underwent dental scaling over five consecutive years had a significantly lower risk of developing PD. These findings emphasize the value of early and consecutive dental scaling to prevent the development of PD.

Using community participation to assess demand and uptake of scaling and polishing in rural and urban environments.

BACKGROUND: One of the control tools for periodontal disease besides individual home care is professional oral prophylaxis that is, Scaling and Polishing (S&P).The aim of this study is to assess the effect of oral health awareness on the demand and uptake of scaling and polishing among dwellers of rural and urban environments. METHODS: This interventional study was conducted in Enugu, Nigeria. A questionnaire was used to obtain data on demographic details, presenting complaints and requests, and prior dental visits from consenting attendees in 4 community outreaches. The number of those demanding for scaling of teeth at point of presentation was extracted from their requests. Oral health talk was then given as the intervention for the study. Periodontal assessment was done using Community Periodontal index (CPI) and participants who received scaling thereafter were recorded. Data were analyzed with SPSS [version 20] employing Chi square to compare categorical variables and p was significant at ≤0.05. Multiple regression analysis of factors affecting oral health awareness was done and outcome of intervention was determined by percentage difference in number of participants demanding and receiving S&P. RESULTS: A total of 454 participants enlisted for the study. The outreaches served as first point of contact with dental professionals for 383 (84.4%) participants. 60 (80%) and 15 (20%) participants demanded for scaling in the urban and rural locations respectively (p = 0.00). Out of 78 with CPI 3 score, only 8 (10.3%) demanded for S&P but uptake was by 73 (93.6%) [p = 0.00]. Outcome of oral health intervention was 80.6% difference among those with periodontitis. Multiple regression analysis of factors showed that participants' locations, that is, rural or urban, was the only factor that significantly affected oral health awareness (C.I = 0.183-0.375, p = 0.000). CONCLUSION: Demand for scaling was sub-optimal but the uptake was satisfactory. Rural or urban location of the participants significantly influenced their oral health awareness. The keenness to take up scaling suggests benefits accruing from the oral health education. Appropriate health policies and planning could help bridge the gap between rural and urban areas and strengthen gains from this study.

Does chemical preconditioning contribute to the effectiveness of scaling and root planing? An in vitro pilot investigation.

OBJECTIVES: A solution based on hypochlorite and amino acids was introduced to improve cleaning efficacy on the root surfaces. The purpose of this in vitro pilot study was to evaluate the time reduction and number of strokes required to clean untreated root surfaces in vitro. METHODS: Sixty extracted human teeth displaying areas with subgingival calculus were assigned equally to one of three treatment groups (n = 20) according to the size of occupied areas, estimated by the number of pixels. The groups were assigned to either 30 s penetration time (I) or 300 s (II) or no pretreatment application (III). The weight for instrumentation was calibrated for a M25A curette (Deppeler/Switzerland) with 500 g. A new set of tools was used for each group, and each instrument was sharpened after single use by an EasySharp Device (Deppeler/Switzerland). RESULTS: The time (in seconds) for instrumentation was recorded as follows: Group I: 32/23.5/50 (median/first quartile/third quartile); group II: 33/20/52.5; group III: 46.5/35.5/52.3. The results for the numbers of strokes were: Group I: 18/14.3/28; group II: 18.5/13/30.5; group III: 17.5/15/25. No statistically significant differences (P < 0.05) were found between the three groups for the variables 'time' and 'number of strokes'. CONCLUSIONS: Within the limits of this in vitro pilot study, preconditioning of the calculus on root surfaces with an alkaline solution failed to reduce the number of strokes and time of instrumentation significantly.

Clinical efficacy of photodynamic therapy adjunctive to scaling and root planing in the treatment of chronic periodontitis: A systematic review and meta-analysis.

PURPOSE: To evaluate the clinical efficacy of photodynamic therapy (PDT) adjunctive to scaling and root planing (SRP) in patients with untreated chronic periodontitis based on up-to-date evidence. METHODS: MEDLINE and the Cochrane Library were systematically searched to identify eligible randomized controlled trials (RCTs), supplemented by a manual literature search. Mean differences (MD) and the corresponding 95% confidence intervals (CI) of probing depth (PD) reduction and clinical attachment level (CAL) gain were synthesized. The I2 test and Q statistics were used to determine the inter-study heterogeneity. Subgroup analysis based on smoking status was performed. RESULTS: Eleven RCTs with a total of 243 subjects were included. Significant improvement in PD reduction (MD=0.13, CI:0.02-0.24, p=0.02) and marginal significant improvement in CAL gain (MD=0.18, CI:-0.005-0.363, p=0.056) were observed in favor of SRP+PDT at 3months. When evaluated at 6months after baseline, the association of PDT with SRP resulted in a significant benefit in PD reduction (MD=0.40, CI:0.05-0.74, p=0.03), but not in CAL gain (MD=0.37, CI:-0.18-0.93, p=0.18). Subgroup analysis revealed that the combined therapy produced no significant improvements in PD and CAL at neither 3months nor 6months for studies with smokers. No treatment-related adverse events or side effects had been reported by the included studies. CONCLUSIONS: Pooled analysis suggests a short-term benefit of PDT as an adjunct to SRP in clinical outcome variables. However, evidence regarding its long-term efficacy is still insufficient and no significant effect has been confirmed in terms of CAL gain at 6months. Future clinical trials of high methodological quality are needed to establish the optimal combination of photosensitizer and laser configuration.

Effect of laser-assisted scaling and root planing on the expression of pro-inflammatory cytokines in the gingival crevicular fluid of patients with chronic periodontitis: A systematic review.

BACKGROUND: The aim of the present systematic review was to assess the efficacy of laser-assisted (low level laser therapy [LLLT], high intensity laser therapy [HILT], or antimicrobial photodynamic therapy [aPDT]) scaling and root planing (SRP) compared with SRP alone on the expression of inflammatory cytokines in the gingival crevicular (GCF) of patients with chronic periodontitis (CP). METHODS: In order to address the focused question: "What is the efficacy of SRP with and without laser and/or aPDT on the expression of pro-inflammatory cytokines in the GCF of patients with CP?" an electronic search without time or language restrictions was conducted up to and including February 2017 in indexed databases using various key words. RESULTS: Twenty-two randomized control trials were included in the present systematic review. Nine studies and six studies assessed the efficacy of LLLT and HILT, as adjunct to SRP, respectively. Seven studies assessed the efficacy of aPDT as adjunct to SRP on down-regulating the expression of pro-inflammatory cytokines in the GCF among patients with CP. The outcomes of the studies included based upon the reduction in the levels of pro-inflammatory cytokines were inconsistent. CONCLUSION: The role of laser-assisted SRP on the expression of pro-inflammatory cytokines in the GCF of patients with CP remains unclear. Further long term and well-designed randomized clinical trials are needed in this regard.

Dental Treatment in a State-Funded Primary Dental Care Facility: Contextual and Individual Predictors of Treatment Need?

OBJECTIVE: This study examined individual and contextual factors which predict the dental care received by patients in a state-funded primary dental care training facility in England. METHODS: Routine clinical and demographic data were extracted from a live dental patient management system in a state-funded facility using novel methods. The data, spanning a four-year period [2008-2012] were cleaned, validated, linked by means of postcode to deprivation status, and analysed to identify factors which predict dental treatment need. The predictive relationship between patients' individual characteristics (demography, smoking, payment status) and contextual experience (deprivation based on area of residence), with common dental treatments received was examined using unadjusted analysis and adjusted logistic regression. Additionally, multilevel modelling was used to establish the isolated influence of area of residence on treatments. RESULTS: Data on 6,351 dental patients extracted comprised of 147,417 treatment procedures delivered across 10,371 courses of care. Individual level factors associated with the treatments were age, sex, payment exemption and smoking status and deprivation associated with area of residence was a contextual predictor of treatment. More than 50% of children (<18 years) and older adults (≥65 years) received preventive care in the form of 'instruction and advice', compared with 46% of working age adults (18-64 years); p = 0.001. The odds of receiving treatment increased with each increasing year of age amongst adults (p = 0.001): 'partial dentures' (7%); 'scale and polish' (3.7%); 'tooth extraction' (3%; p = 0.001), and 'instruction and advice' (3%; p = 0.001). Smokers had a higher likelihood of receiving all treatments; and were notably over four times more likely to receive 'instruction and advice' than non-smokers (OR 4.124; 95% CI: 3.088-5.508; p = 0.01). A further new finding from the multilevel models was a significant difference in treatment related to area of residence; adults from the most deprived quintile were more likely to receive 'tooth extraction' when compared with least deprived, and less likely to receive preventive 'instruction and advice' (p = 0.01). CONCLUSION: This is the first study to model patient management data from a state-funded dental service and show that individual and contextual factors predict common treatments received. Implications of this research include the importance of making provision for our aging population and ensuring that preventative care is available to all. Further research is required to explain the interaction of organisational and system policies, practitioner and patient perspectives on care and, thus, inform effective commissioning and provision of dental services.

"Low Testosterone Levels in Body Fluids Are Associated With Chronic Periodontitis".

There is a debate over the association between low testosterone levels in body fluids and the occurrence of chronic periodontitis (CP). The aim of the present systematic review was to assess whether low testosterone levels in body fluids reflect CP. In order to identify studies relevant to the focus question: "Is there a relationship between low testosterone levels in body fluids and CP?" an electronic search without time or language restrictions was conducted up to June 2016 in indexed databases using different keywords: periodontitis, chronic periodontitis, periodontal diseases, testosterone, and gonadal steroid hormones. A total of eight studies were included in the present systematic review. The number of study participants ranged from 24 to 1,838 male individuals with ages ranging from 15 to 95 years. Seven studies measured testosterone levels in serum, two studies in saliva, and one study in gingiva. Four studies reported a negative association between serum testosterone levels and CP. Two studies reported a positive association between decreased testosterone levels in serum and CP. Increased levels of salivary testosterone among patients with CP were reported in one study; whereas one study reported no significant difference in the concentration of salivary testosterone between patients with and without CP. One study identified significant increase in the metabolism of testosterone in the gingiva of patients with CP. Within the limits of the evidence available, the relationship between low testosterone levels and CP remains debatable and further longitudinal studies and control trials are needed.

Frequent Dental Scaling Is Associated with a Reduced Risk of Periprosthetic Infection following Total Knee Arthroplasty: A Nationwide Population-Based Nested Case-Control Study.

Oral bacteremia has been presumed to be an important risk factor for total knee arthroplasty (TKA) infection. We aimed to investigate whether dental scaling could reduce the risk of TKA infection. A nested case-control study was conducted to compare 1,291 TKA patients who underwent resection arthroplasty for infected TKA and 5,004 matched controls without infection in the TKA cohort of Taiwan's National Health Insurance Research Database (NHIRD). The frequency of dental scaling was analyzed. Multiple conditional logistic regression was used to assess the frequency of dental scaling and the risk of TKA infection. The percentage of patients who received dental scaling was higher in the control group than in the TKA infection group. The risk for TKA infection was 20% lower for patients who received dental scaling at least once within a 3-year period than for patients who never received dental scaling. Moreover, the risk of TKA infection was reduced by 31% among patients who underwent more frequent dental scaling (5-6 times within 3 years). Frequent and regular dental scaling is associated with a reduced risk of TKA infection.

Association between periodontal disease and pregnancy outcomes.

OBJECTIVE: To evaluate the association between periodontal disease and pregnancy outcomes like preterm birth and low birth weight. PATIENTS AND METHOD: Interviewer-administered questionnaires were completed by the subjects who attended the antenatal clinic of the Lagos University Teaching Hospital, Lagos. Information obtained included; maternal age, gestational age, marital status, educational status, occupation and expected date of delivery. After delivery, the questionnaire was completed with baby's weight at birth and the actual date of delivery. Clinical assessment of the periodontium was done using Oral Hygiene Index (OHI) and Community Periodontal Index of Treatment Needs (CPITN). Participants were divided into three groups: Test, Control I and Control II groups. Scaling and polishing were done for all patients with periodontal disease before (Test group) and after delivery (Control I). All Control II participants (those without periodontal disease) were given Oral hygiene instructions. Descriptive and comparative analyses were done using Epi info version 2008. RESULTS: Four hundred and fifty women received the questionnaire but the response rate was 94%, giving an actual sample size of 423 participants. Maternal age range was between 18 and 34 years with mean age of 29.67 (± 3.37). Gestational age at the point of recruitment was between 10 weeks and 26 weeks with mean of 23.34 (± 4.05). The prevalence of periodontal disease among the study group was 33.38%. About 71% of the participants attained tertiary level of education; only 0.7% had no formal education. There was 9.9% use of alcohol among the participants. The mean oral hygiene score for the participants was 1.94 (± 1.31). The prevalences for preterm deliveries, low birth weight and spontaneous abortion were 12.5%, 12.1% and 1.42% respectively. CONCLUSION: This study confirms periodontal disease as a probable risk for adverse pregnancy outcomes such as preterm delivery and low birth weight. Therefore, health workers should be encouraged to promote good oral health among women.

Community periodontal treatment needs in South Korea.

OBJECTIVES: This study aimed to assess the relationship between socio-economic factors and community periodontal treatment needs in Korea. METHODS: Data were obtained from the year 2009 Korean National Health and Nutrition Examination Survey. Our analysis included 7510 survey participants over the age of 19 years. To assess the relationship between socio-economic factors and the need for periodontal scaling, we performed multivariate logistic regression analyses for data with a complex sampling structure. PASW statistics 19.0 (SPSS Inc., Chicago, IL, USA) was used to perform the statistical analyses, and the results were expressed as odds ratios (OR) with corresponding 95% confidence intervals (CIs). RESULTS: A very high percentage of Korean adults required periodontal scaling (71.5%). After adjusting for sex, age, and socio-economic factors, the need for periodontal scaling was associated with low levels of education (OR: 1.41, 95% CI: 1.03-1.93), low incomes (OR: 1.27, 95% CI: 1.01-1.60), employment as a service and sales worker (OR: 1.39, 95% CI: 1.10-1.77), and employment as a manual worker (OR: 1.31, 95% CI: 1.02-1.69). CONCLUSIONS: In South Korea, the need for periodontal scaling was associated with socio-economic factors, such as low levels of education, low incomes, employment as a service and sales worker and employment as a manual worker. Consequently, clinical and community dental hygienists should consider adults with these risk factors as belonging to high-priority subgroups to whom they should respond first.

Income-related inequalities in preventive and curative dental care use among working-age Japanese adults in urban areas: a cross-sectional study.

BACKGROUND: Preventive dental care use remains relatively low in Japan, especially among working-age adults. Universal health insurance in Japan covers curative dental care with an out-of-pocket payment limit, though its coverage of preventive dental care is limited. The aim of this study was to test the hypothesis that income inequality in dental care use is found in preventive, but not curative dental care among working-age Japanese adults. METHODS: A cross-sectional survey was conducted using a computer-assisted, self-administered format for community residents aged 25-50 years. In all, 4357 residents agreed to participate and complete the questionnaire (valid response rate: 31.3%). Preventive dental care use was measured according to whether the participant had visited a dentist or a dental hygienist during the past year for dental scaling or fluoride or orthodontic treatments. Curative dental care use was assessed by dental visits for other reasons. The main explanatory variable was equivalent household income. Logistic regression analyses with linear trend tests were conducted to determine whether there were significant income-related gradients with curative or preventive dental care use. RESULTS: Among the respondents, 40.0% of men and 41.5% of women had used curative dental care in the past year; 24.1% of men and 34.1% of women had used preventive care. We found no significant income-related gradients of curative dental care among either men or women (p = 0.234 and p = 0.270, respectively). Significant income-related gradients of preventive care were observed among both men and women (p < 0.001 and p = 0.003, respectively). Among women, however, income-related differences were no longer significant (p = 0.126) after adjusting for education and other covariates. Compared with men with the lowest income, the highest-income group had a 1.79-fold significantly higher probability for using preventive dental care. CONCLUSIONS: The prevalence of preventive dental care use was lower than that of curative care. The results showed income-related inequality in preventive dental care use among men, though there were no significant income-related gradients of curative dental care use among either men or women. Educational attainment had a positive association with preventive dental care use only among women.

The effect of rubber dam usage on the survival rate of teeth receiving initial root canal treatment: a nationwide population-based study.

INTRODUCTION: It is well-known that the usage of rubber dams during root canal treatment (RCT) improves infection control and treatment efficacy and protects patients. However, the effect of rubber dam usage on endodontic outcomes remain uncertain. The aim of the present study was to investigate whether rubber dam usage affects the survival rate of initial RCT using a nationwide population-based database. METHODS: A total of 517,234 teeth that received initial RCT between 2005 and 2011 met the inclusion criteria and were followed until the end of 2011. Univariate and multivariate Cox proportional hazards models were used to estimate the effects of rubber dam usage on the risk of tooth extraction after initial RCT. RESULTS: Of the 517,234 teeth, 29,219 were extracted, yielding a survival rate of 94.4%. The survival probability of initial RCT using rubber dams after 3.43 years (the mean observed time) was 90.3%, which was significantly greater than the 88.8% observed without the use of rubber dams (P < .0001). After adjusting for age, sex, tooth type, hospital level, tooth scaling frequency per year after RCT, and systemic diseases, including diabetes and hypertension, the tooth extraction hazard ratio for the RCT with rubber dams was significantly lower than that observed for RCT without rubber dams (hazard ratio = 0.81; 95% confidence interval, 0.79-0.84). CONCLUSIONS: The use of a rubber dam during RCT could provide a significantly higher survival rate after initial RCT. This result supports that rubber dam usage improves the outcomes of endodontic treatments.

[Active periodontitis as a potential risk factor of preferm delivery]. / Aktywne zapalenie przyzebia jako potencjalny czynnik ryzyka wystapienia porodu przedwczesnego.

The influence of active periodontitis on the incidence of preterm delivery has been widely described in numerous scientific papers. Studies suggest that an implementation of a periodontal treatment during pregnancy is not only safe for both, the mother and the child, but it also has a beneficial effect on the pregnancy and embryo-fetal development, consequently reducing morbidity and mortality among premature infants. Therefore, mandatory dental examinations in pregnant women may facilitate early implementation of periodontal treatment and reduce the rates of preterm delivery

Examining related influential factors for dental calculus scaling utilization among people with disabilities in Taiwan, a nationwide population-based study.

Limited studies with large samples have been conducted on the utilization of dental calculus scaling among people with physical or mental disabilities. This study aimed to investigate the utilization of dental calculus scaling among the national disabled population. This study analyzed the utilization of dental calculus scaling among the disabled people, using the nationwide data between 2006 and 2008. Descriptive analysis and logistic regression were performed to analyze related influential factors for dental calculus scaling utilization. The dental calculus scaling utilization rate among people with physical or mental disabilities was 16.39%, and the annual utilization frequency was 0.2 times. Utilization rate was higher among the female and non-aboriginal samples. Utilization rate decreased with increased age and disability severity while utilization rate increased with income, education level, urbanization of residential area and number of chronic illnesses. Related influential factors for dental calculus scaling utilization rate were gender, age, ethnicity (aboriginal or non-aboriginal), education level, urbanization of residence area, income, catastrophic illnesses, chronic illnesses, disability types, and disability severity significantly influenced the dental calculus scaling utilization rate.

Oral health of older people admitted to hospital for needs assessment.

OBJECTIVES: To describe the clinical oral health status, treatment needs and oral-health-related quality of life (OHRQoL) of older people admitted to older persons' wards at Dunedin Public Hospital due to a sudden worsening of their general health. Participants and methods: A systematic oral assessment was undertaken for a consecutive case series of 200 patients (59.5% female; mean age 82.6 years, sd 6.6) admitted to older person's wards at Dunedin Public Hospital. The Oral Health Impact Profile-20 (OHIP-20) was used to assess OHRQoL. RESULTS: One in three (36.0%) had been living independently at home prior to admission, and over half (55.0%) had been admitted for a medical reason which required assessment. Half (50.0%) of the participants were dentate (with an average of 16.8 teeth). There was an average of 1.9 decayed teeth present in the dentate group; 70.7% of individuals required restorations or extractions, and about 90% required only simple scaling of the teeth and prophylaxis. A reline or a replacement denture were required by three-quarters of those with dentures. Almost two-thirds of participants did not have a regular dentist, and fewer than one in three had made a dental visit in the previous year. One in six described their oral health as 'fair' or 'poor', and just under one-third reported dry mouth. Dentate participants, those without xerostomia, and those reporting better oral health had better OHRQoL, reflected in lower OHIP-20 scores. Affecting 37.1% of participants, functional limitation was the most commonly experienced of the OHIP-20 domains, followed by physical disability and physical pain (18.0% and 15.6% respectively). CONCLUSIONS: The oral health of medically compromised and functionally dependent but cognitively competent older people in this study is generally poor. If transfer to long-term care is indicated, early and proper preventive measures and appropriate dental contact should be advocated in order to reduce morbidity and improve quality of life for older people.

Avaliação dos parâmetros clínicos periodontais, da qualidade de vida e da experiência de dor, medo e ansiedade em indivíduos submetidos às técnicas de raspagem e alisamento radicular por quadrante e ao protocolo de one-stage full-mouth disinfection no tratamento da periodontite crônica: um ensaio clínico randomizado controlado / Evaluation of periodontal clinical parameters, quality of life and pain experience, fear and anxiety in individuals treated by scaling and root planing per quadrant and the protocol of one- stage full-mouth disinfection in the treatment of chronic periodontitis: a randomized controlled clinical trial

O objetivo do presente ensaio clínico controlado randomizado cego foi avaliar e comparar o efeito de duas modalidades de terapia periodontal inicial, raspagem e alisamento radicular por quadrante (RAR-Q) e one-stage full-mouth disinfection (FMD), nos parâmetros clínicos periodontais, qualidade de vida, medo, ansiedade e experiência de dor, em indivíduos com periodontite crônica. Foram aplicados os instrumentos Oral Impacts on Daily Performances (OIDP), Oral Health and Quality of Life (OHQoL) Dental Fear Survey (DFS), Dental Anxiety Scale (DAS) e Escala Visual Analógica (EVA), em 78 indivíduos divididos em 2 grupos de tratamento: RAR-Q (n=37) e FMD (n=41). Os parâmetros clínicos periodontais: profundidade de sondagem (PS), nível de inserção clínica (NIC), índice de placa (IPL), índice gengival (IG) e % sítios doentes (PS¿4mm e NIC¿3mm), foram coletados. As avaliações foram realizadas no exame inicial ou T0 (parâmetros clínicos periodontais, DAS e DFS), 30 dias após término do tratamento ou T1 (OIDP e OHQoL) e 180 dias após o tratamento ou T2 (parâmetros clínicos periodontais, OHQoL, OIDP, DAS e DFS). A aplicação da EVA foi realizada imediatamente após a finalização da terapia. Para a análise estatística foram utilizados o teste de Kruskal-Wallis, correlação de Pearson, teste de Wilcoxon e Análise de Conglomerados, com o objetivo de determinar perfis diferenciados dos indivíduos, baseado nos questionários OHQoL, OIDP, DAS e DFS. As análises foram realizadas através do software SPSS 17.0 e os resultados foram considerados significativos para p¿0,005. Observou uma correlação negativa significativa dos resultados do OHQOL com os parâmetros NIC (-0,35), IPL (-0,23) e IG (-0,27) e uma correlação positiva significativa do OIDP com os parâmetros NIC (0,41) e % de sítios doentes (0,23), no T0/T1. A mesma correlação significativa se manteve em T2, com exceção do parâmentro IPL. A análise de conglomerados identificou dois clusters: A (n=33) maior impacto/pior qualidade de vida, maior medo e ansiedade e, B (n=42) menor impacto/melhor qualidade de vida, com menor medo e ansiedade. Houve uma redução significativa em todos os parâmetros clínicos periodontais quando comparadas as avaliações antes e após o tratamento e uma associação negativa entre medo e ansiedade com os parâmetros NIC, IPL e IG. Ambos os grupos apresentaram queda no medo e ansiedade após o tratamento: FMD (p=0,019) e RAR-Q (p=0,043). Os grupos apresentaram média semelhante para a escala de dor: FMD (2,6 ±1,9) e RAR-Q (2,7 ±2,0) (p=0,930). Concluímos que os indivíduos tratados pela RAR-Q e pelo FMD apresentaram melhora nos parâmetros clínicos periodontais e qualidade de vida, sem diferenças significativas entre os grupos. Não houve diferenças significativas entre o tratamento pela RAR-Q e FMD nos níveis de dor, o mesmo ocorreu para ansiedade e medo, em T0/T1 e T2

The aim of this blinded randomized controlled clinical trial was to evaluate and compare the effect of two types of non-surgical periodontal therapy, scaling and root planing per quadrant (SRP) and one-stage full-mouth disinfection (FMD) in periodontal clinical parameters, quality of life, fear, anxiety and pain experience in patients with chronic periodontitis. The instruments Oral Impacts on Daily Performances (OIDP), Oral Health and Quality of Life (OHQoL) Dental Fear Survey (DFS), Dental Anxiety Scale (DAS) and Visual Analogue Scale (VAS) were applied in 78 subjects divided into 2 treatment groups: SRP (n=37) and FDM (n=41). The periodontal clinical parameters: probing depth (PD), clinical attachment level (CAL), plaque index (PI), gingival index (GI) and % of diseased sites (PD4mm and CAL3mm), were collected. Assessments were performed at baseline or T0 (periodontal clinical parameters, DAS and DFS), 30 days after periodontal therapy or T1 (OIDP and OHQoL) and 180 days after periodontal therapy or T2 (periodontal clinical parameters, OHQoL, OIDP, DAS and DFS). The application of VAS was performed immediately after completion of therapy. For statistical analysis, the Kruskal-Wallis test, Pearson correlation, Wilcoxon test were performed. Besides a Cluster Analysis were perormed in order to determine distinct profiles of individuals, based on questionnaires OHQoL, OIDP, DAS and DFS. Analyses were performed using SPSS 17.0 software and the results were considered significant for p0,005. It was observed a significant negative correlation between OHQOL scores and CAL (-0.35), PI (-0.23) and GI (-0.27) and a significant positive correlation between OIDP and CAL (0.41) and % of diseased sites (0.23), in T0/T1. The same significant correlation was maintained in T2, except for the periodontal clinical parameter PI. Cluster analysis identified two clusters: A (n = 33) greater impact/worse quality of life, greater fear and anxiety, and B (n = 42) lower impact/better quality of life, less fear and anxiety. There was a significant reduction in all periodontal clinical parameters comparing the results before and after treatment and a negative association between fear and anxiety, and CAL, PI and GI. Both groups showed a decline in fear and anxiety after treatment: FMD (p=0.019) and SRP (p=0.043). Both groups showed similar mean for pain scale: FMD (2.6 ± 1.9) and RAR-Q (2.7 ± 2.0) (p = 0.930). We conclude that individuals treated by SRP and the FMD showed an improvement in all periodontal clinical parameters and quality of life, with no significant differences between them. There were no significant differences between treatment by SRP and FMD in the scores of pain, the same occurred for anxiety and fear in T0/T1 and T2. Key words: periodontal debridment, quality of life, fear, anxiety, pain
