ABSTRACT

OBJECTIVES: The aim of this work was to determine dentists' ability to accurately estimate patients' anxiety level during dental treatment (ie, "empathic accuracy") and to determine the strength of the association between empathic accuracy and patient-reported reassurance. METHODS: A cross-sectional study was conducted amongst 177 adult patients who underwent different invasive dental procedures (ie, extractions or procedures requiring injections and drilling) performed by 10 different dentists from 3 dental offices in the Netherlands. Patients reported their anxiety level during treatment and the extent to which they felt reassured by the dentist using a visual analogue scale (VAS). Simultaneously, the dentists estimated patients' anxiety level. Empathic accuracy was calculated as an absolute difference between patient-reported anxiety (100-point VAS) and dentist estimation of anxiety (100-point VAS). RESULTS: Agreement between dentists' assessment of patients' anxiety and patient-reported anxiety proved good, intraclass correlation coefficient (177) = 0.63; 95% confidence interval [CI], 0.53-0.71. A small to medium-sized positive correlation, r (177) = 0.15; 95% CI, 0.00-0.29, was found between dentists' empathic accuracy and patient-reported reassurance. A negative correlation was found between empathic accuracy and patients' anxiety scores, r (177) = -0.23; 95% CI, -0.38 to -0.09. CONCLUSIONS: Given that greater empathic accuracy was associated with higher patient-reported reassurance during treatment, training young dental professionals in empathic accuracy might help patients feel reassured. Importantly, our results also suggest that with elevated levels of patient anxiety it is increasingly challenging for dentists to recognise this emotion, and thus support the patient in anoptimal manner.

ABSTRACT

Background: Promising results from a trauma reactivation study on post-traumatic stress disorder suggest that propranolol is capable of attenuating symptoms of traumatically induced mental disorders by blocking memory reconsolidation. Methods: A randomized, parallel, placebo-controlled, quadruple-blind trial was designed to determine the effectiveness of perioperative propranolol during exposure to dental extractions in reducing dental anxiety in patients with dental anxiety or dental phobia. Between November 2014 and December 2018, 52 patients with high levels of fear in anticipation of dental extractions who were referred to a department of oral and maxillofacial surgery for at least two tooth and/or molar removals with 1 month in between were included. On the first visit participants received either 120 mg of perioperative oral propranolol (n = 19) or placebo (n = 17), and a core fear memory was reactivated 1 h preoperatively. The primary outcome was change in severity of dental anxiety from baseline to 1-month follow-up, as indexed by the short version of the dental anxiety inventory (S-DAI). Secondary outcome measures were change in intra-operative state anxiety and specific phobia diagnoses. Results: Linear mixed model (LMM) yielded no statistically significant difference in change of dental trait anxiety from baseline to 1-month follow-up between propranolol and placebo groups (Cohen's d = 0.23). S-DAI scores decreased in both study arms from baseline to follow-up (propranolol arm: from 32.1 [SD = 7.3] to 29.1 [SD = 8.8]; placebo arm: from 31.6 [SD = 7.5] to 27.1 [SD = 6.5]). Also, administering propranolol was not associated with a significant difference in change of intra-operative state anxiety or phobia diagnoses between groups over time. Conclusions: The results do not concur with earlier findings regarding post-traumatic stress disorder, and suggest that individuals with traumatically induced fears or phobias do not benefit from the application of perioperative propranolol.

ABSTRACT

The short form of the Fear of Dental Pain Questionnaire (s-FDPQ) is a validated measure developed to screen patients for their fear of pain associated with dental procedures. As there is a high prevalence of dental fear/anxiety in Chinese adults, the primary aim of our study was to translate the s-FDPQ into standard Mandarin and explore its reliability and validity with Chinese adults. The second aim of our study was to explore fear of dental pain (FDP) scores in relation to dental attendance, anxiety and gender. We translated the s-FDPQ using the forward-backward method. It was completed by 480 Chinese adults alongside the Modified Dental Anxiety Scale (MDAS; Chinese version) to test convergent validity. 109 participants completed the s-FDPQ again 14 days later to evaluate test-retest reliability. The Chinese s-FDPQ (s-CFDPQ) was internally consistent (alpha = 0.87) and demonstrated convergent validity (r = 0.73 when correlated with the MDAS). Test-retest reliability was good (ICC = 0.86). Individuals who had never attended the dentist (22%) had higher FDP scores than those that had, even if they were not dentally anxious. Also, females reported higher FDP scores (p < 0.001). These findings suggest that the s-CFDPQ is a reliable and valid measure for assessing fear of dental pain in Chinese adults. The s-CFDPQ could allow quick identification of individuals who are fearful of dental pain who may require specialist attention.

ABSTRACT

OBJECTIVE: To evaluate whether periapical surgery affects oral health-related quality of life (OHRQoL) within the first postoperative week. STUDY DESIGN: The primary outcomes in 133 patients (54 men, 79 women; mean age 50.8 years) undergoing periapical surgery were the Oral Health Impact Profile-14 (OHIP-14) score and postoperative sequelae, including pain, analgesic intake, swelling, limited mouth opening, chewing difficulties, and postoperative infection. RESULTS: We found a significant effect on OHIP-14, pain, and analgesics, which decreased throughout the week. We found no significant differences in mean OHIP-14, pain scores, or analgesic use for gender, medical history, surgical flaps, operation time, or location of the operated teeth. Younger patients had a higher OHIP-14 score in the first 2 days after surgery and more pain on the first postoperative day. Women experienced more pain during the first 3 days. Smokers had a higher OHIP-14 score on the first postoperative day and greater pain during the first 3 days compared to non-smokers. CONCLUSION: We identified a low incidence of pain and reduced OHRQoL following periapical surgery. The postoperative reduction in OHRQoL and pain were of short duration, with maximum intensity in the early postoperative period and rapidly decreasing with time.

ABSTRACT

OBJECTIVE: The aim of this study was to evaluate the effect of an iodine tampon on postoperative discomfort after surgical removal of a mandibular third molar. MATERIAL AND METHODS: Patients were randomly assigned to two groups: one group received an alveolar iodine-containing tampon in the extraction socket (N = 44), and the other group used a disposable syringe (Monoject®) to rinse the wound (N = 43). Postoperative discomfort was assessed with the Oral Health Impact Profile-14 (OHIP-14) questionnaire, Pain Intensity Numerical Rating Scale (PI-NRS), and questions about self-care and discomfort. RESULTS: This study included 87 patients (52 women and 35 men) with an average age of 26.47 years (SD, 6.36). The mean OHIP-14 sum scores were significantly lower in the iodine tampon group compared with the Monoject® syringe group. Mean PI-NRS scores significantly differed between the iodine tampon group (3.33; SE, 0.27) and Monoject® syringe group (4.46; SE, 0.27) (F (1, 85) = 8.16, p < 0.01), with no interaction effect between time and PI-NRS (F (6, 510) = 1.26, p = 0.28). Patients in the iodine tampon group reported less postoperative discomfort. CONCLUSIONS: Insertion of an iodine-containing tampon in the postoperative socket reduced the pain and impact on oral health-related quality of life during the first postoperative week and positively influenced postoperative sequelae.

ABSTRACT

BACKGROUND/AIM: The effectiveness of mouthguards used in field hockey is unknown. The aim of this study was to compare the maximum impact heights between currently used mouthguards in field hockey to prevent dental injury. METHODS: Four boil-and-bite mouthguards (Dita, Shock Doctor, SISU, and Stag) and one custom-made mouthguard (Elysee) were tested for maximum impact height. A hockey ball was released in a tube from increasing heights onto plaster and polymethylmethacrylate (PMMA) dental models. Models were tested without mouthguard as a control. The experiment was repeated 10 times per mouthguard and for the control on each dental model. The maximum impact height for when the dental model broke was used to calculate the speed. The mouthguards and controls were compared. RESULTS: The maximum impact heights (median [25%-75%] in meters) onto plaster dental models were as follows: control 0.23 (0.15-0.25), Dita 0.35 (0.30-0.35), Elysee 0.45 (0.34-0.50), Shock Doctor 0.68 (0.60-0.74), SISU 0.23 (0.20-0.26), and Stag 0.35 (0.35-0.46). The maximum impact height for Shock Doctor was significantly higher than all other mouthguards and the control (all P < .05). The maximum impact heights onto PMMA dental models were as follows: control 2.00 (1.30-2.50), Dita 3.80 (2.65-6.95), Elysee 3.30 (2.30-4.20), Shock Doctor 6.20 (2.80-8.10), SISU 2.60 (1.90-3.15), and Stag 3.90 (1.25-5.15). The maximum impact height for Shock Doctor was significantly higher than for SISU, Stag, and the control (all P < .05), but did not differ significantly from Dita (P = .43) and Elysee (P = .12). CONCLUSION: Shock Doctor had the highest maximum impact height compared to the other mouthguards and appears to be the most effective mouthguard tested in this study.

ABSTRACT

Changes in oral health status following treatment should be assessed clinically as well as by patients' reported outcomes. This study investigated changes on oral-health-related quality of life (OHRQoL) of adolescents enrolled in a comprehensive oral health care program for caries and gingival conditions. The sensitivity of the Child Perception Questionnaire11-14 (CPQ11-14) to detect clinical changes, that is, its responsiveness, was assessed. A total of 618 10-15-year adolescents answered the questionnaire before treatment and 560 at follow-up after 1 year. In the follow-up, 2 additional global transition judgment questions were asked. The adolescents were clinically and radiographically examined. At the baseline, 374 adolescents needed only nonoperative treatment, whereas 274 needed non- and operative treatments. After 1 year, the adolescents were regrouped according to the fulfillment of their treatment needs in Group 1 (n = 363) needing/receiving nonoperative treatment only; Group 2 (n = 98) needing/receiving both non- and operative treatments; Group 3 (n = 99) receiving nonoperative treatment only, while needing also operative treatment. The CPQ11-14 total mean change scores by the global transition judgment on self-perceived oral health status indicated significant differences (p < 0.001, ANOVA; internal responsiveness). The effect of the program for the treatment groups was significant (p = 0.014, ANCOVA; external responsiveness). The effect size for the change scores was of moderate magnitude. In conclusion, an overall improvement of adolescents' OHRQoL was observed following 1-year oral health care program for caries and gingival conditions. The CPQ11-14 was internally and externally sensitive to detect substantial clinical changes. The CPQ11-14 seems appropriate for measuring long-term changes on adolescents' OHRQoL.

ABSTRACT

PURPOSE: The aim of this study was to assess the efficacy of an iodine tampon after mandibular third molar surgery on oral health-related quality of life (OHRQoL), use of painkillers, postoperative sequelae, and self-care behaviors in the first postoperative week. MATERIALS AND METHODS: This prospective, crossover, randomized controlled study included patients undergoing surgical removal of bilateral symmetrically, horizontally impacted mandibular third molars. The surgical site was randomly allocated to receive an iodine tampon after surgery or wound closure and rinsing with a Monoject syringe (Tyco/Healthcare-Kendall, Mansfield, MA). The primary outcomes measured each day during the first postoperative week were the Oral Health Impact Profile 14 score and postoperative sequelae, including pain, swelling, limited mouth opening, postoperative infection, and alveolar osteitis. The secondary outcome measures were several self-care behaviors. Data were analyzed using repeated-measures analysis of variance and paired-samples t tests. RESULTS: A total of 54 patients (25 men and 29 women; mean age, 25.1 years) were enrolled, with a total of 108 surgically removed impacted mandibular third molars. The use of an iodine tampon resulted in a significantly lower impact on OHRQoL (mean of 21.5 [standard deviation (SD), 9.6] vs 26.5 [SD, 10.6]) on the first postoperative day, which was observable until the seventh postoperative day. In addition, after removal of the impacted third molar, patients with the iodine tampon condition reported less pain (mean of 5.2 [SD, 1.9] vs 6.1 [SD, 2.1] on day 1, lasting throughout the week), less use of painkillers, less limited mouth opening, fewer problems chewing, less swelling, and earlier recovery. CONCLUSIONS: The use of postoperative iodine packing after the removal of impacted mandibular third molars significantly reduces OHRQoL and postoperative sequelae.

ABSTRACT

AIMS: To develop models for prognostic prediction of oral health-related quality of life (OHRQoL) for patients with temporomandibular joint osteoarthritis (TMJ OA) at 1- and 6-month follow-ups after arthrocentesis treatment with hyaluronic acid (HA) injections once a week for 4 weeks. METHODS: From a cohort of 522 adult patients with TMJ OA treated with arthrocentesis with HA injections, 510 and 463 adult patients were included in the 1- and 6-month follow-ups, respectively. Patient characteristics and history, clinical examinations, and questionnaires were recorded as potential predictors at start of treatment, and all patients underwent an identical treatment protocol. Patients' OHRQoL values at 1 and 6 months after completing the treatment were used as outcome measures. Logistic regression methods were used to develop prediction models, and the performance and validity of these models were evaluated according to state-of-the-art methods, including receiver-operating characteristics curve for the discrimination of the models and calibration plots for the calibration of the models. RESULTS: History of mental disease, maximal protrusion of the jaw, muscular pain with palpation, joint pain with palpation, awake bruxism, chewing-side preference, and low OHRQoL at baseline were significantly associated with OHRQoL at the 1-month follow-up, while age, pain in other joints, history of mental disease, joint pain with palpation, sleep bruxism, awake bruxism, chewing-side preference, and low OHRQoL at baseline were significantly associated with OHRQoL at the 6-month follow-up. While the performance of both models was found to be good in terms of calibration, discrimination, and internal validity, the added predictive values of the 1-month and 6-month models for ruling in the risk of low OHRQoL were 19% and 31%, respectively, while those for ruling it out were 28% and 15%, respectively. CONCLUSION: Several predictors were found to be significantly associated with patients' OHRQoL after treatment. Both prediction models may be reliable and valid for clinicians to predict a patient's risk of low OHRQoL at follow-up, so the models may be useful for clinicians in decision-making for patient management and for informing the patient.

ABSTRACT

AIMS: To identify potential predictors of types of treatment indicated for patients with temporomandibular disorders (TMD) and to develop, validate, and calibrate a prediction model for type of treatment. METHODS: The derivation cohort at baseline was comprised of 356 adult patients with TMD. Patient and disease characteristics were recorded at baseline as potential predictors. Types of treatment indicated for TMD patients were the end points of the model, classified into no treatment, physical treatment only (including splint and/or physiotherapy), and combined physical and psychological treatment. Multinomial logistic regression analysis was used to develop the prediction model. The internal validation, calibration, discrimination, and external validation of the model were determined. For practical use, the prediction model was converted into score charts and line charts. The score of each included predictor was produced based on the shrunken regression coefficients. RESULTS: Patient age, gender, anxiety, sleep bruxism, pain-related TMD, function-related TMD, stress, passive stretch of maximum mouth opening, and depression were significantly associated with the type of treatment indicated for TMD patients. The multinomial model showed reasonable calibration and good discrimination, with area under the curve values of 0.76 to 0.86. The internal validity of the model was good, with a shrinkage factor of 0.89. The external validity of the model was acceptable. CONCLUSION: Potential predictors in patient profiles for prediction of type of treatment indicated for TMD patients were identified. The internal validity, calibration, discrimination, and external validity of the model were acceptable.

ABSTRACT

OBJECTIVES: The aim was to assess the added diagnostic value of ultrasonography (US) for establishing the presence or absence of disc displacements (DDs) in temporomandibular joints (TMJs). MATERIALS AND METHODS: Pubmed and EMBASE were searched electronically to identify diagnostic accuracy studies that assessed the diagnostic value of US for the diagnosis of DD, using Magnetic resonance imaging (MRI) as the reference standard. Meta-analyses were performed with Metadisc 1.4 and RevMan 5.3. RESULTS: A total of 16 studies qualified for meta-analyses. For the diagnosis of DD at closed mouth position (DD-CM) and DD at maximum mouth-opening position (DD-MMO), the added values of a positive result with US for ruling in DD-CM and DD-MMO were 22 and 41%, while those of a negative result with US for ruling out DD-CM and DD-MMO were 30 and 20%. For the diagnosis of DD with reduction (DDWR) and DD without reduction (DDWoR), the added values of a positive result in US for ruling in DDWR and DDWoR were 35 and 41%, while those of a negative result in US for ruling out DDWR and DDWoR were 21 and 27%. CONCLUSIONS: Using MRI as reference standard, the added values of both positive predictive values and negative predictive values of US for ruling in and ruling out DDs are sufficient in the decision-making in dental practice. CLINICAL RELEVANCE: US can be a good imaging tool to supplement clinical examination findings in patients with suspected DDs. Combined static and dynamic examinations using high-resolution US should be preferred.

ABSTRACT

OBJECTIVE: The aim of this study was to determine whether patients with a pain score ≥7 (high pain group) after a mandibular block injection had a higher physiologic response compared with patients with scores <7 (low pain group). STUDY DESIGN: Before oral surgery, patients (n = 66) filled out questionnaires to measure anxiety and expected pain. The questionnaires also assessed patients' experiences with dental injections and dental anxiety, as well as their emotional state and intensity of anxiety. Before, during, and after the injection, physiologic responses were measured by using Nexus-10. Patients were then asked about the pain and anxiety they had experienced. RESULTS: The mean score for pain experienced was 3.45 (standard deviation 2.17) on an 11-point rating scale. Eight patients (12.1%) experienced high injection pain. There was a significant increase in mean sweat secretion and a significant decrease in mean respiration between the relaxing phase and the injection phase. There was a significant positive relationship between experienced anxiety and mean heart rate during the injection phase. No significant difference in physiologic response was found between patients who experienced high pain and those who experienced low pain. CONCLUSIONS: Reported pain was not associated with the physiologic response of patients receiving mandibular block injections.

ABSTRACT

OBJECTIVE: The study aim was to investigate variations in the symmetry of the zygomaticomaxillary complex (ZMC) in normal individuals. METHOD: Computed tomography datasets of 200 individuals without facial fractures were analyzed using a validated three-dimensional analysis technique. The absolute average distance (AD) and 90th percentile distance (NPD) were calculated, representing respectively the overall and maximum symmetry between bilateral ZMCs. RESULTS: The mean AD and NPD of the total study group was 0.9 ± 0.3 mm (95% CI 0.3-2.3) and 1.7 ± 0.5 mm (95% CI 0.5-3.9), respectively. The mean AD and NPD in males were 1.0 ± 0.3 mm (95% CI 0.28-2.34) and 1.9 ± 0.5 mm (95% CI 0.5-3.9) versus 0.8 ± 0.3 mm (95% CI 0.4-1.7) and 1.6 ± 0.5 mm (95% CI 0.8-2.9), respectively, for females. A statistically significant difference between male and female was found for both AD and NPD (p < 0.01). The male population <40 years had a mean AD and NPD of 1.0 ± 0.3 mm and 1.8 ± 0.5 mm, which was not statistically significant when compared with males >40 years. CONCLUSION: The naturally occurring anatomic variation in ZMC symmetry described in this study is proposed as a benchmark for evaluating the amount of preoperative displacement and postoperative reduction of ZMC in trauma cases.

ABSTRACT

OBJECTIVE: The aim of this study was to evaluate the analgesic effects of low-level laser therapy (LLLT) on preinjection sites in patients scheduled for third molar removal. STUDY DESIGN: This double-blind randomized controlled trial included 163 healthy patients undergoing third molar extractions. The study participants were randomly divided into an LLLT and a placebo group. Objective and subjective data sets were obtained from physiologic feedback (heart rate and sweat response) and a questionnaire, respectively. In the LLLT group, each targeted injection site was irradiated twice with 198 mW continuous wave for 30 seconds with a 0.088 cm2 focal spot at an applied energy of 5.94 J and fluence of 67.50 J/cm2. Measurements were recorded from 4 time-points during data acquisition. RESULTS: There was no significant difference between the LLLT and placebo groups in pain experience scores associated with the injected sites for maxillary or mandibular third molar extractions. Mean heart rates before and during injection were lower in the LLLT group than in the placebo group for both maxillary and mandibular regions. No statistically significant differences were observed for any remaining parameters. CONCLUSIONS: The present data indicated that preinjection LLLT did not effectively decrease the pain felt during local anesthetic injections before third molar surgery.

ABSTRACT

There is limited empirical information as to whether or how stimuli associated with dental fear can be classified into distinct subtypes. The purpose of the current study was to develop a descriptive framework for the classification of dental fear. Data were collected using a survey among Dutch twin families (n = 11,771). The sample was randomly divided into two subsamples of, respectively, 5,920 and 5,851 individuals. An exploratory factor analysis (EFA) was performed on the first subsample to delineate the multidimensional structure of a set of 28 dental-fear-provoking objects and situations. The second sample was used to confirm the newly derived model using confirmatory factor analysis (CFA). The EFA yielded a three-factor solution with 70.7% explained variance pertaining to: (i) invasive treatment or pain; (ii) losing control; and (iii) physical sensations. The CFA showed an acceptable fit to the data, thereby confirming the stability of the three-factor structure. There are at least three different subtypes of dental fear. As these subtypes require a different treatment approach in clinical practice, it could be important to assess the severity of patients' fear response along these three dimensions.

ABSTRACT

The importance of exposure to traumatic events for the development of dental anxiety has not been investigated. The aim of the present study was to test the hypotheses that individuals who reported having been exposed to a traumatic event [that is, fulfilling Criterion A of the Diagnostic and Statistical Manual of Mental Disorders, 5th Edition (DSM-5), for post-traumatic stress disorder (PTSD)] as the cause of their dental anxiety would report significantly higher levels of dental anxiety, typical trauma-related (PTSD) symptoms, and greater disturbance of memories involving these events than those who reported being exposed to non-traumatic events. Patients of a specialized dental fear clinic (n = 90) were divided into those who reported a traumatic event that initiated their dental trait anxiety and those who did not. The two groups did not differ in their severity of dental anxiety and number of PTSD symptoms, but the memories of those who had been exposed to traumatic events were significantly more vivid than the memories of those in the reference group. Length of time since the event took place did not play a role. Hence, traumatic events are remembered more vividly, but do not seem to initiate more severe forms of dental anxiety than other events.

ABSTRACT

OBJECTIVES: Partial tooth agenesis is frequently observed in Robin sequence. Tooth anomalies are increasingly considered as an extended phenotype of the cleft palate population. The study objective was to compare the prevalence and patterns of tooth agenesis in a group of patients with non-syndromic Robin sequence (ns-RS) and a group with non-syndromic cleft palate (ns-CP). MATERIALS AND METHODS: The panoramic radiographs of 115 ns-RS and 191 ns-CP patients were assessed for agenesis of the permanent dentition (excluding third molars) and the patterns recorded using the Tooth Agenesis Code. RESULTS: Partial tooth agenesis was observed in 47.8% of ns-RS and 29.8% of ns-CP patients with a greater prevalence in the mandibula than in the maxilla, particularly in ns-RS. The teeth most frequently absent in both groups were the mandibular second premolars and maxillary lateral incisors. Tooth agenesis was bilateral in two-thirds of affected ns-RS patients and one-half of ns-CP patients. In ns-RS, bilateral agenesis of the mandibular second premolars was more frequently observed in female than that in male patients. Completely symmetrical patterns of hypodontia were found in around 45% of ns-RS patients with tooth agenesis compared to 35% in ns-CP. No association was found between the extent of the palatal cleft and the severity of hypodontia. CONCLUSION: Tooth agenesis is more prevalent in ns-RS than that in ns-CP, demonstrates a much greater predilection for the mandible in ns-RS, and bears no relation to the extent of the palatal cleft. CLINICAL RELEVANCE: When compared to ns-CP, additional developmental disturbances are likely involved in the etiology of tooth agenesis in ns-RS. Future research could help identify the underlying genetic traits and aid in classifying patients in those with and without expected tooth agenesis in order to facilitate orthodontic management strategies.

ABSTRACT

BACKGROUND: The association between periodontitis and atherosclerotic cardiovascular diseases (ACVD) has been established in some modestly sized studies (<10 000). Rarely, however, periodontitis has been studied directly; often tooth loss or self-reported periodontitis has been used as a proxy measure for periodontitis. Our aim is to investigate the adjusted association between periodontitis and ACVD among all individuals registered in a large dental school in the Netherlands (Academic Centre for Dentistry Amsterdam (ACTA)). METHODS: Anonymised data were extracted from the electronic health records for all registered patients aged >35 years (period 1998-2013). A participant was recorded as having periodontitis based on diagnostic and treatment codes. Any affirmative answer for cerebrovascular accidents, angina pectoris and/or myocardial infarction labelled a participant as having ACVD. Other risk factors for ACVD, notably age, sex, smoking, diabetes, hypertension, hypercholesterolaemia and social economic status, were also extracted. Logistic regression analyses were used to evaluate the adjusted associations between periodontitis and ACVD. RESULTS: 60 174 individuals were identified; 4.7% of the periodontitis participants (455/9730) and 1.9% of the non-periodontitis participants (962/50 444) reported ACVD; periodontitis showed a significant association with ACVD (OR 2.52; 95% CI 2.3 to 2.8). After adjustment for the confounders, periodontitis remained independently associated with ACVD (OR 1.59; 95% CI 1.39 to 1.81). With subsequent stratification for age and sex, periodontitis remained independently associated with ACVD. CONCLUSIONS: This cross-sectional analysis of a large cohort in the Netherlands of 60 174 participants shows the independent association of periodontitis with ACVD.

ABSTRACT

BACKGROUND: To determine the impact of self-perceived halitosis on social interactions, and the effect of using an oral rinse for management of halitosis. METHODS: A survey among a representative sample of the Dutch population (n = 1082), and a pre-post study among a sample of consecutive coming-by volunteers (n = 292). RESULTS: Participants of the representative sample rated their oral odor as 66.8 ± 17.2 and the consecutive volunteers as 70.9 ± 16.7 (range: 0-100). Sizable proportions (15.3 % and 38.1 %, respectively) indicated to always take into account their (bad) oral odor when meeting a person for the first time. The worse people perceived their oral odor, the more likely they were to take into account to keep a certain distance. Following the use of the oral rinse, a significant decline was found of the extent to which the participants reported to take into account their oral odor when meeting a person for the first time. Both studies identified a subgroup of individuals (9.1 % and 28.1 % respectively) who reported to keep a certain distance when meeting other people, despite a "fresh" self-perceived oral odor. CONCLUSION: The results suggest that self-perceived oral odor negatively affects social interactions, and that adequate management of halitosis has the potential to improve such interactions.
