Occlusal splint and combined multiwave locked system laser therapy demonstrated differential patient-reported outcomes and clinical parameters: A randomized controlled trial in patients with temporomandibular disorder

PURPOSE

To evaluate the impact of occlusal splint plus laser therapy (OS + LT) compared with OS alone on the patient-reported outcomes and clinical parameters of patients with temporomandibular disorders (TMDs).

METHODS

Twenty-three patients with TMDs were randomly assigned to two treatment approaches: OS and OS + LT (multiwave locked system). The two outcomes were clinical parameters (mouth-opening distances, number of muscles and TMJs with pain) and patient-reported outcomes (pain score and oral health-related quality of life [OHRQoL] determined using the 14-item oral health impact profile [OHIP-14]). The outcomes were measured at four time points: baseline, 2 weeks, 1 and 3 months after treatment. According to DC/TMD Axis I classification, the participants were diagnosed as having pain only and pain with intraarticular joint disorder. Adjusting for age and sex, the outcome changes were analysed using generalized estimating models at a 5% significance level.

RESULTS

The pain-free mouth-opening distance of the patients who received OS + LT continuously increased from 2 weeks to 3 months. However, the value was significantly increased at 3 months in patients who received OS alone. The unassisted mouth-opening distance significantly increased after 3 months in both groups. In both treatment approaches, the number of muscles and TMJs with pain, as well as the pain and OHIP-14 scores gradually decreased from baseline to 3 months.

CONCLUSIONS

The patients who received OS and OS + LT demonstrated better OHRQoL and clinical parameters during 3 months after treatment. An improvement in the pain-free mouth-opening distance at 2 weeks was found only in OS plus LT group; however, this difference may not be clinically significant.

Using the Child Perceptions Questionnaire with young adults

OBJECTIVES

That no study has investigated oral health-related quality of life (OHRQoL) through the transition from adolescence to young adulthood is partly due to no OHRQoL index having been validated in both adult and child populations. Having separate measures for adolescence and young adulthood has meant that the different measures cannot be compared directly. Accordingly, the study objectives were: to determine whether the CPQ11-14 is a valid and reliable OHRQoL measure in young adults and to compare its performance with the OHIP-14 in young adults.

METHODS

A cross-sectional study was undertaken of a convenience sample of 968 young New Zealand adults aged 18-30 years (83.1% female) using RedCap. Two separate measures of OHRQoL were used (the CPQ11-14 and OHIP-14), along with Locker's global oral health item.

RESULTS

Internal consistency reliability was high for the CPQ11-14 and the OHIP-14, with Cronbach's alpha scores of .87 and .92, respectively. Mean scale scores were 15.8 (SD = 9.7) for the CPQ11-14 and 24.1 (SD = 10.1) for the OHIP-14. The scale scores were strongly and positively correlated (Pearson's r = .8). Both demonstrated acceptable construct validity, represented by ascending gradients in mean scores across the ordinal response categories of Locker's global oral health item. Ordinal logistic regression modelling of Locker's item showed the CPQ11-14 to have a slightly better fit and explain more variance than the OHIP-14.

CONCLUSION

The CPQ11-14 was valid and reliable in this young adult population. Further epidemiological validation studies should confirm the findings in representative samples.

Oral Health-Related Quality of Life in Adult Patients with Depression or Attention Deficit Hyperactivity Disorder (ADHD)

The aim of this cross-sectional study was the evaluation of the oral health-related quality of life (OHRQoL) in patients with depression or attention-deficit/hyperactivity disorder (ADHD) in comparison with a group of mentally healthy individuals. Patients from the Department of Psychiatry and Psychotherapy, University of Leipzig, Germany, were recruited. A healthy comparison group (HC) was recruited from the Department of Cariology, Endodontology and Periodontology. The OHRQoL was assessed using the Oral Health Impact Profile G14 (OHIP G14). Furthermore, a questionnaire regarding oral hygiene behaviour was applied. A total of 141 patients with depression or ADHD (depression n = 94, ADHD n = 47) and 145 HC individuals with a balanced age and gender distribution were surveyed. OHIP G14 median scores were significantly higher in the overall psychiatric patient group compared to HC (5.00 vs. 0.00, p < 0.001). This was also found for the four dimensions of OHIP G14 (p < 0.001). The OHIP G14 sum score of patients with depression and ADHD was comparable (5.00 vs. 6.50, p = 0.302). A significant association among psychiatric patients between smoking, gum bleeding, professional tooth cleaning, oral health education, interdental cleaning, and elevated OHIP scores was found (p < 0.001). In conclusion, patients with depression and adults with ADHD show a reduced OHRQoL. A contradictory association between oral hygiene/oral health behaviour and OHRQoL supports the hypothesis of a changed perception of oral conditions in patients with mental diseases. Interdisciplinary collaboration between psychiatric specialists and dentists should be fostered.

Factors influencing xerostomia and oral health-related quality of life in polymedicated patients

OBJECTIVES

To evaluate whether the severity of xerostomia in older polymedicated patients impacts oral health-related quality of life (OHRQoL).

BACKGROUND

Medication-associated xerostomia is common in older people. Xerostomia may impair OHRQoL.

MATERIALS AND METHODS

This cross-sectional study included older hypertensive patients from two health centres. We assessed the severity of xerostomia and OHRQoL using the Xerostomia Inventory (XI) tool, and the Oral Health Impact Profile-14 (OHIP-14) instrument, respectively. We measured unstimulated (UWS) and stimulated (SWS) salivary flows. Univariate and multiple linear regression analyses evaluated the associations of XI and OHIP-14 and different explanatory variables.

RESULTS

Of the 218 patients enrolled, 51.8% had xerostomia, and 38.1% and 27.5% suffered from UWS and SWS hyposalivation, respectively. Patients with xerostomia, UWS, and SWS hyposalivation scored significantly higher on the XI. However, only those with xerostomia or UWS hyposalivation had significantly higher OHIP-14 scores. A moderate correlation was observed between XI and OHIP-14 scores. The multiple regression model showed that factors with the greatest impact on XI were the patient's complaint of xerostomia, UWS flow rate, age and sex. However, only the XI score was significantly associated with the OHIP-14 score.

CONCLUSION

Xerostomia has a negative impact on OHRQoL in older polymedicated patients, but this impact is less than in other types of xerostomia. Longitudinal studies are needed to determine whether changes in the detected explanatory variables influence XI and OHIP scores in these patients.

Influence of Root Canal Treatment on Oral-Health-Related Quality of Life (OHRQoL) in Saudi Patients: A Cross-Sectional Study

Objective This cross-sectional study aimed to assess the influence of root canal treatment on the oral-health-related quality of life (OHRQoL) of patients in the Kingdom of Saudi Arabia (KSA). The data on KSA's population are significantly limited, highlighting the significance of additional research to be carried out in this particular field. Methods The study was conducted at the dental clinics of the College of Dentistry, Qassim University, from January to June 2022. A total of 112 patients who had undergone endodontic therapy (ET) for teeth with irreversible pulpitis were included. Demographic data and treatment procedures were recorded. The patients' responses to the OHIP-14 questionnaire were analyzed to assess their OHRQoL. The scores were converted into qualitative categories (good, moderate, poor) for classification. Results The majority of patients (59.8%) reported a good OHRQoL after ET. Physical pain was the only variable where more than 50% of patients reported experiencing pain. Older age and smoking status were significantly associated with a poorer OHRQoL. However, no significant gender differences in OHRQoL were observed. Conclusion ET had a positive impact on the OHRQoL of patients in Saudi Arabia. The study highlights the importance of considering patient-centered outcomes, such as OHRQoL, in assessing the success of root canal treatment. Further research with longitudinal designs and randomized controlled trials is needed to better understand the long-term effects of root canal treatment on patients' OHRQoL and to compare them with other dental treatments.

Impact of Dental Anxiety on Dental Care Routine and Oral-Health-Related Quality of Life in a German Adult Population-A Cross-Sectional Study

The interaction between dental anxiety and the establishment of a consistent dental care routine has been an ongoing challenge. Unfortunately, there is limited available data concerning the detailed dental care practices of individuals with dental anxiety. Therefore, this study aims to explore how dental anxiety influences dental care habits and oral-health-related quality of life within an adult population. By utilizing the Dental Anxiety Scale (DAS) and the German Oral Health Impact Profile (OHIP-G5), we assessed their extent. To evaluate the differences, we performed analyses of variance (Anova), an independent t-test and rank correlation. The findings of this study unveil a significant correlation between elevated DAS scores and reduced frequency of tooth brushing; calculus removal and appointments for professional teeth cleaning. Interestingly; the use of dental floss and mouthwash solution as well as toothbrush hardness appeared to be not significantly affected by dental fear. Moreover, individuals with dental anxiety demonstrated a preference for manual toothbrushes over electric ones. In addition, higher DAS scores were found to be strongly associated with greater OHIP-G5 scores, thus leading to a substantial decline in overall oral health-related quality of life.

Impact of Acrylic and Silicone-Based Soft-Liner Materials on Biting Force and Quality of Life of the Complete Denture Wearers: A Randomized Clinical Trial

This rerandomized clinical trial evaluated the influence of soft liners (SL) on biting force, pain perception, and the oral health-related quality of life (OHRQoL) of complete denture wearers. Twenty-eight completely edentulous patients complaining of ill-fitting lower complete dentures were selected to participate in the study from the Dental Hospital, College of Dentistry, Taibah University. All patients received new complete maxillary and mandibular dentures; then they were randomly divided into two groups (14 patients in each group): the acrylic-based SL group, in which the mandibular denture was lined with an acrylic-based soft liner, and the silicone-based SL group, in which the mandibular denture was lined with a silicone-based soft liner. OHRQoL and maximum bite force (MBF) were assessed in this study before denture relining (baseline), then at one month and three months after relining. The finding showed that both treatment modalities significantly improved the OHRQoL of included patients at one-month and three-month periods compared to baseline records (i.e., dentures before relining) with a statistically significant difference (p < 0.05). However, there is no statistical difference between groups at the baseline, one-, and three-month follow-up periods. Regarding maximum biting force, when acrylic-based SL is compared to silicone-based SL, there is no statistical difference between groups at baseline (75 ± 31 and 83 ± 32 N) and one-month follow-up periods (145 ± 53 and 156 ± 49 N); however, after three months of function, the silicone-based group recorded 166 ± 57 N statistically significant high biting force compared to the acrylic-based group that recorded 116 ± 47 N (p < 0.05). Permanent soft denture liners positively affect maximum biting force, pain perception, and OHRQoL more than conventional dentures. After three months, silicone-based SL outperformed acrylic-based soft liners in maximum biting force, which may indicate better long-term results.

Reliability and Validity of a Lithuanian Version of the Oral Health Impact Profile-A Study in Patients with Stage III-IV Periodontitis

Background and Objectives: The study aimed to translate the original English version of Oral Health Impact Profile (OHIP) into Lithuanian and to assess reliability and validity of the translated instrument (OHIP-Lt) in patients with advanced stages of periodontitis. Materials and Methods: Subjects (N = 67) with stage III-IV periodontitis aged 30-63 years were surveyed by questionnaire and examined clinically. Psychometric analysis included explanatory (EFA) and confirmatory (CFA) factor analyses and psychometric tests. Results: Cronbach's alpha of the translated OHIP was 0.96. EFA revealed four dimensions which Cronbach's alpha ranged from 0.75 to 0.96. Construct validity of the four-factor model derived from the OHIP-Lt was supported by findings of CFA (RMSEA = 0.077). The total OHIP-Lt and its subscale scores increased as the patients' self-rated oral health status changed from healthy to unhealthy. Discriminative validity of the OHIP-Lt was confirmed by its higher scores among patients who had an increased spacing between the maxillary anterior teeth and increased clinical attachment level (CAL ≥ 5 mm) compared to those who did not. Conclusions: The translated Lithuanian version of OHIP-Lt was identified as four-dimension inventory. Good reliability and validity of the OHIP-Lt provide the evidence for its further use in study on advanced periodontal disease burden among Lithuanian patients.

Does anxiety have an impact on temporomandibular disorders? A study in a Turkish sample by using specific questionnaires

OBJECTIVE

The aim of the study is to verify the impact of anxiety on temporomandibular disorders (TMD) by using specific questionnaires in a Turkish sample.

METHODS

This survey was conducted on 292 patients with a mean age of 38.59 ± 10.38 using Helkimo index, Oral Health Impact Profile (OHIP-14), and State Trait Anxiety Inventory (STAI). Spearman Correlation and Fisher Freeman Halton analyses were used for the statistical analysis.

RESULTS

There was no statistically significant difference between the Helkimo anamnestic dysfunction (HAD) levels in terms of OHIP-14 total scores or STAI state scores. There was, however, a statistically positive correlation between STAI state and OHIP-14 total values at 18.4%, a positive correlation between the STAI trait and OHIP-14 total values at 29.8%.

CONCLUSION

No significant correlation was observed between OHIP-14 total scores, STAI state scores, and HAD levels. Therefore, this study did not find a significant relationship between TMDs and anxiety.

Dental Students' Oral Health-Related Quality of Life and Temporomandibular Dysfunction-Self-Rating versus Clinical Assessment

The aim of this study was to compare dental students' self-perception of oral health with the results of a clinical examination of the masticatory system. Seventy-four dental students (38 (51.4%) females and 36 (48.6%) males) completed the Oral Health Impact Profile questionnaire (OHIP-G-14) and underwent a clinical examination according to the Graz Dysfunction Index (GDI). Data were analyzed with descriptive and comparative statistics. Median OHIP-G-14 scores were 3 (IQR 0-6) in the total collective, 4 (1-11) in females, and 2 (0-4) in males (p = 0.072). A score of 0 was found in 29.7% of the sample. The results of the GDI were 50% "normal function", 43.2% "adaptation", 5.4% "compensation", and 1.4% "dysfunction". The comparison of OHIP-G-14 scores and DGI groups showed a significant difference (p = 0.031). Based on the questionnaire, less than one third of the sample indicated maximum oral health-related quality of life. In contrast, the GDI revealed "normal function" or "adaptation" in 93.2%. Dental students underappreciated their oral health condition. Health assessments should not be solely questionnaire-based, especially in health professionals (-to-be). To establish a valid diagnosis of the state of health, self-assessment must be complemented by an objective clinical examination, e.g., GDI.

Older Seniors during the COVID-19 Pandemic-Social Support and Oral Health-Related Quality of Life

The coronavirus disease (COVID-19) has greatly affected all parts of private life and led to social distancing and self-isolation. Limited social support for older or frail people might have led to decreased oral health and its related quality of life. The current study aimed to investigate the social support of older seniors and self-perceived oral health-related quality of life (OHRQoL) over the course of the COVID-19 pandemic. Questionnaires were sent to all patients of the Dental Clinic of the University of Leipzig (Germany) aged 75, 80, or 85 years (n = 1228) at the end of February 2021. Besides demographic characteristics and care level, an adapted German version of the ENRICHD Social Support Inventory (ESSI-D) and the German Oral Health Impact Profile-14 (OHIP-14) were included. The response rate was 35.7% (n = 439). Twelve replies were not included in the data analysis as participants had either no interest, were cognitively impaired, or did not match the required age group. Analysis of ESSI-D revealed low social support for 13.2% (n = 53/403) of the seniors. No statistically significant impact of assigned care level on low social support was identified. Seniors with an assigned care level (CLyes) presented higher OHIP-14 sum scores (CLno/CLyes 6.43/10.12; p < 0.001). This was also true for six of the seven OHIP-14 domains, except for functional limitation. Regarding seniors with an assigned care level, a weak positive correlation was identified for sum scores of the ESSI-D and the OHIP-14 (r = 0.29). Despite the COVID-19 pandemic, older seniors reported high self-perceived social support. As seniors with an assigned care level revealed more impaired OHRQoL and a correlation with lower social support, special attention should be given to this vulnerable and frail group in times of a pandemic. When restrictions may minimize access to dental treatment and might negatively influence the oral health of older seniors, health care programs should offer more individual options for dental/medical appointments.

Pre-Operative Oral Health-Related Quality of Life in Patients Attending Surgical Removal of Mandibular Third Molar Teeth

The study aimed to measure the pre-operative oral health-related quality of life (OHRQoL) and to identify patient and teeth pathologies associated with worse OHRQoL among patients attending mandibular third molar tooth extraction. Data were collected preoperatively from 199 patients attending surgical removal of their mandibular third molar. To that end, we measured the Oral Health Impact Profile-14 (OHIP-14) and analyzed its association with: (1) demographics; (2) health-related behaviors such as smoking, alcohol consumption, physical activity, and dietary habits; (3) Plaque Index (PI); (4) Decay, Missing, and Filled Teeth (DMFT); and (5) clinical characteristics related to third molar extraction, such as the indication for extraction, tooth angulations, and radiographic pathology. The mean age of the study population was 21.5 ± 3.2 years and the mean OHIP-14 global score was 22.5 ± 8.3. The present study identified patient and teeth profiles that are associated with worse pre-operative OHRQoL in patients attending mandibular third molar extraction. The “vulnerable patient” profile includes poor health-related behaviors, particularly the performance of physical activity less than once a week (p = 0.028). The “disturbing teeth” profile includes higher plaque scores (p = 0.023) and specific characteristics of the third molar teeth, such as pericoronitis (p = 0.027) and radiolucency around third molars in panoramic radiography (p < 0.001). These findings support the hypothesis that OHRQoL is a complex phenomenon which is associated with the patient’s health-related behaviors as well as with specific tooth pathologies.

Evaluation of temporomandibular disorders, quality of life, and oral habits among dentistry students

Objective: To evaluate temporomandibular disorders (TMD), quality of life, and oral habits in dentistry students.Methods: The study was performed with 480 students (287 females, 193 males). The Fonseca Questionnaire, Oral Health Impact Profile-14 (OHIP-14), and Oral Behaviors Checklist (OBC) were used.Results: The mean scores of the fifth-year students from Fonseca TMD, OHIP-14, and OBC were statistically significantly higher than those of the students in other years of study. The mean Fonseca score of female students was higher than those of the males. There was a statistically significant difference regarding the OHIP-14 scores based on the Fonseca TMD scores. A statistically significant difference regarding OBC was present based on the Fonseca TMD scores.Conclusion: The prevalence of TMDs was higher among the senior dentistry students. Necessary measures should be taken in the dentistry educational system to raise students' quality of life, improve joint disorders, and eliminate current oral habits.

Influence of depression and self-esteem on oral health-related quality of life in students

Objective

We aimed to investigate the influence of depression and self-esteem on oral health-related quality of life (OHRQoL) in students.

Methods

Among the 67 included participants, we measured self-esteem using the Rosenberg Self-Esteem Scale, severity of depression using the Patient Health Questionnaire-9 (PHQ-9), personality dimensions with the Neuroticism–Extraversion–Openness Five-Factor Inventory, and OHRQoL using the Oral Health Impact Profile 49 (OHIP-49).

Results

Among all participants, 7.5% (n = 5) had the dominant personality trait openness to experience, 11.9% (n = 8) presented a neurotic personality type, and 64.% (n = 11) had an extraverted personality type. The most frequent was conscientious personality type, accounting for 64.2% (n = 43) of participants. Our results showed a significant correlation between increased PHQ-9 scores and OHIP scores (Spearman’s r = 0.280); thus, participants with poorer oral health tended to have more severe depression. An increase in depression severity was significantly and positively correlated with increased scores across the other two OHIP subcategories, physical pain (Spearman’s r = 0.314) and physical disability (Spearman’s r = 0.290).

Conclusion

The presence and severity of depression influences OHRQoL. An important factor in the presence of depression and level of self-esteem is the personality type, especially the neuroticism dimension.

Comparison of Oral Health Impact Profile (OHIP-14) Values in Cancer Survivor Patients Treated Orthodontically with Either Rapid or Standard Duration Protocols of Treatment-A Prospective Case-Control Study

BACKGROUND

The aim of the study was to compare the oral-health-related quality of life (OHRQoL) between cancer survivors: with rapid orthodontic treatment (TX) (up to 12 months) and standard TX (orthodontic treatment time longer than 16 months).

METHODS

There were 76 cancer survivors (48 women and 28 men) allocated into groups with rapid (36 people) or standard (40 people) duration of TX. OHRQoL was assessed on the basis of Oral Health Impact Profile (OHIP-14) values, measured before TX, 2 weeks and 3 months after the onset of TX, and after the end of TX. A repeated ANOVA test was used to check the statistical significance between the scores.

RESULTS

There were no significant differences regarding the OHIP-14 values between the examined groups at all stages of the examination. Both groups presented significant (p < 0.001) improvement of the values of OHRQoL at the end of TX comparing to the values achieved before the onset of TX.

CONCLUSIONS

Duration of orthodontic treatment by itself had no impact on oral-health-related quality of life.

Oral health-related quality of life in different rheumatic diseases

OBJECTIVES

Aim of this cross-sectional study was to investigate oral health-related quality of life (OHRQoL) of patients with different rheumatic diseases.

SUBJECTS AND METHODS

Patients with rheumatic disease, including rheumatoid arthritis (RA), systemic lupus erythematodes (SLE), systemic sclerosis (SSc), ankylosing spondylitis (AS), psoriatic arthritis (PsA) and vasculitis were included. OHRQoL was assessed with the German short form of oral health impact profile (OHIP G14). Age, disease duration, leukocytes, c-reactive protein (CRP) and haemoglobin counts were considered as disease related parameters.

RESULTS

A total of 356 patients, assigned to the groups RA (n = 218), SLE (n = 36), AS (n = 36), PsA (n = 33), vasculitis (n = 19) and SSc (n = 14) were included. The OHIP G14 sub-scale psychosocial impact differed significantly between groups (p = .02). The OHIP G14 sum score was also significantly different between groups (p < .01). A medium-sized correlation was found for CRP with OHIP G14 sum score within SLE group (r = .344, p = .04). A large correlation was detected for leukocytes within PsA group (r = .525, p < .01). The reliability of the applied OHIP G14 was high.

CONCLUSION

Patients with rheumatic disease show a reduced OHRQoL, with several differences between the entities. Psychosocial aspects appear to be of relevance and should be considered in multidisciplinary dental care of these patients.

Dental trauma experience and oral-health-related quality of life among university students

BACKGROUND

This study aimed to investigate the impact of self-reported dental trauma on oral-heath-related quality of life (OHRQoL) of young adults and determine whether personality characteristics influenced how it was reported.

METHOD

A cross-sectional study was carried out using a sample of 435 university students. A questionnaire sought data on previous dental trauma. OHRQoL was assessed using the short-form of the oral health impact profile (OHIP-14); the outcome being one or more impacts occurring 'fairly often'/'very often'. Personality was assessed using the Positive and Negative Affect Scale (PANAS).

RESULTS

The participation rate was 87.2%. Dental trauma experience was reported by 110 participants (25.3%), and 242 (55.6 %) indicated previous dental caries experience. Among those with dental trauma history, one or more OHIP-14 impacts was reported by 29.1% (with 21.2% among those with no history). Impact prevalence was higher among those who had previous dental caries experience (29.8%) than among those who had not (14.7%; P < 0.001). Higher PANAS negative affect scores were observed among those reporting one or more OHIP-14 impacts (P < 0.001).

CONCLUSION

While dental trauma does not appear to have a negative impact on OHRQoL in young adults, past dental caries experience does. Negative emotionality influences self-reported oral health.

[Reliability and validity of the Chinese version of the 5-item oral health impact profile]

OBJECTIVE

To evaluate the reliability and validity of the Chinese version of the 5-item oral health impact profile (OHIP-5).

METHODS

According to the international guidelines, the Chinese version of the OHIP-5 was produced. It was applied to patients who visit our clinic. The reliability of the scale was evaluated by internal consistency reliability and test-retest reliability. In addition, the validity of the scale was evaluated by construct validity and convergent validity.

RESULTS

A total of 556 patients were enrolled in the study. The Cronbach's alpha and the intraclass correlation coefficient values (ICC) of the Chinese version of the OHIP-5 were 0.868, 0.831, respectively. The results of the confirmatory factor analysis (CFA) showed that the one-factor model provided an acceptable fit to the data. The fit indices were: the chi-square fit statistics/degree of freedom (χ²/df)=2.419, the goodness-of-fit index (GFI)=0.995, the adjusted goodness of fit index (AGFI)= 0.960, the normed fit index (NFI)=0.996, the incremental fit index (IFI)=0.997, the Tucker-Lewis index (TLI)= 0.985, the comparative fit index (CFI)=0.997, and the root mean square error of approximation (RMSEA)=0.070. For the convergent validity of the scale, the Spearman's rank correlation coefficient was 0.674.

CONCLUSIONS

The Chinese version of OHIP-5 had a good reliability and validity by rigorous psychometric properties. Overall, it can be further promoted in clinical research and epidemiological investigations.

Oral health-related quality of life in tumour patients treated with patient-specific dental implants

Dental rehabilitation after surgically acquired bone deficiency related to tumour treatment remains a challenge. The insertion of patient-specific implants geared to the contour of the remaining bone is a feasible method of supporting fixed or removable dentures. As oral health-related quality of life (OHRQoL) is of great interest in these cases, 12 individuals treated with patient-specific implants for severe bone deficiency were surveyed and their Oral Health Impact Profile (OHIP) scores after dental rehabilitation were evaluated. The OHIP-G53 questionnaire was used to measure overall treatment outcomes. The distribution of OHIP sum-scores for participants treated with patient-specific implants was almost homogeneous when compared to those cited in the literature for patients treated with conventional dental implants. OHIP items related to functional impairment and physical pain showed the highest scores (occurring occasionally), and financial loss related to treatment was frequently stated. Moreover, higher scores were detected in almost all OHIP dimensions for participants with patient-specific implant-supported removable dentures. Conversely, those treated with patient-specific dental implants and fixed dentures showed lower psychosocial impact scores and equal or superior OHRQoL. Hence, patient-specific dental implants, especially combined with fixed dentures, can lead to a positive OHRQoL in patients with severe bone deficiencies related to tumour therapy.

Evaluation of temporomandibular disorder symptoms and oral health-related quality of life in adolescent orthodontic patients with different dental malocclusions

Objective: To estimate the prevalence of temporomandibular disorders in adolescent orthodontic patients with different dental malocclusions and to assess the relationship between oral health-related quality of life.Methods: This study was carried out on 648 randomly selected individuals 14-19 years of age. Diagnostic Criteria for Temporomandibular Disorders (DC/TMD), Fonseca Questionnaire, and Oral Health Impact Profile-14 (OHIP-14) forms were used.Results: TheGCPS,TMDPain,Fonseca,OHIP-14, PHQ-9, GAD-7,OBC,andPHQ-15 mean scores of female participants were statistically significantly higher than males (p < 0.05).There was a significant difference among the malocclusion groups in terms of their mean scores in GCPS, Fonseca, and OHIP-14 (p < 0.05).The age values and JFLS, TMD Pain, Fonseca, OHIP-14, PHQ-9, GAD-7, and PHQ-15 were statistically significant correlations in the positive direction.Conclusion: The DC/TMD form allows both a physical assessment of Axis I and II that examines psychosocial status and pain-related disorders and a more comprehensive assessment. The mean OHIP-14 and Fonseca questionnaire scores of Class III groups were found to be significantly higher.

Evaluation of temporomandibular disorders and oral health-related quality of life with obese patients

Objective: The aim of this study was to investigate the relationship between temporomandibular disorders and oral health impact profile in healthy, overweight, and obese patients.Methods: This study was carried out on 1528 individuals divided into three groups as healthy, overweight, and obese patients. Diagnostic Criteria for Temporomandibular Disorders, Fonseca's questionnaire, and Oral Health Impact Profile-14 (OHIP-14) forms were used.Results: Gender, classification, pain, temporomandibular joint noise, and open-lock of the jaw of healthy, overweight, and obese groups were found to be related. The differences in the Fonseca and the OHIP-14 total scores according to the groups were found to be statistically significant. The correlation between the Fonseca total score and age was positive and significant.Conclusion: In the obese patients, both total Fonseca and OHIP-14 values were found to be higher. Also, the presence of pain in the obese patients was found to be higher.

Effects of Xerostom® products on xerostomia in primary Sjögren's syndrome: A randomized clinical trial

OBJECTIVES

To assess the effects of Xerostom^® toothpaste and mouthwash in primary Sjögren's syndrome (pSS) patients with xerostomia.

SUBJECTS AND METHODS

A double-blinded, randomized study where patients were assigned at baseline test or control products. Patients used the products 3 times/day/28 days. We used a visual analogue scale (VAS) for xerostomia and an Oral Health Impact Profile-14 (OHIP-14), baseline and after treatment, to assess possible improvement.

RESULTS

A total of 28 patients with pSS were included in this study, but only 24 finished it (all women, mean age 55.21 ± 11.87), and 13 patients received the test and 11 the control. VAS and OHIP-14 scores decreased in both groups after treatment but significant differences between groups were not found. We do not detect VAS intragroup significant differences before and after treatment in test and control groups. A significant improvement in OHIP-14 was identified in the treatment group, while no significant differences were observed in the control group. No adverse effects were present.

CONCLUSIONS

Xerostom^® toothpaste and mouthrinse may alleviate and improve quality of life without associated side effects, but further research with a larger number of participants and follow-up are necessary to establish the positive efficacy of these topical products in pSS patients.

Oral health-related quality of life in patients under supportive periodontal therapy

OBJECTIVE

To assess the oral health-related quality of life (OH-QoL) in patients under supportive periodontal therapy (SPT) and the influence of the individual periodontal risk as well as different degrees of adherence during SPT on OH-QoL.

MATERIALS AND METHODS

309 patients with at least 5 years of SPT were re-examined. Periodontal risk profile (according to Lang and Tonetti) was assessed and the adherence to SPT-appointments within the last 30(±6) months was reviewed for each patient (fully adherent: adherence to all appointments ±6 weeks, partially adherent: SPT-interval not extended more than half of the recommended interval, insufficiently adherent: SPT-interval extended more than half of the recommended interval, non-adherent: recommended SPT-interval interruption ≥12 months). OH-QoL was measured using the German short-version of the Oral Health Impact Profile (OHIP-G14). Differences between groups (Mann-Whitney U test, Kruskal-Wallis test), association between total OHIP-scores and the predictors age, mean periodontal probing depth and oral hygiene parameters were tested (Spearman's correlation). A multivariable linear regression model was fitted using all categorical predictors with a univariable p value <.1.

RESULTS

Statistical analysis revealed no significant differences in OHIP-G14 scores for gender, periodontal diagnosis and prosthetic status. Patients with deep periodontal pockets (≥6 mm) showed significantly higher OHIP-G14 scores compared to patients without deep pockets (p = .049). Adherence and periodontal surgery were statistically significant predictors for the OHIP-G14 score.

CONCLUSIONS

OH-QoL of patients under long-term SPT seems to be influenced by periodontal status. Good compliance with SPT-intervals based on the individual periodontal risk profile seems to contribute to a better OH-QoL compared to irregular attendance of SPT.

Effect of a comprehensive plan for periodontal disease care on oral health-related quality of life in patients with periodontal disease in Taiwan

A comprehensive plan for periodontal disease (PD) care in Taiwan provides non-surgical and supportive periodontal treatment. The aim of this study was to determine whether the care plan could improve the oral health-related quality of life of patients with PD.This study was conducted by purposive sampling and a quasi-experimental design. Patients with PD were assigned to either comprehensive periodontal treatment (n = 32) or a simple cleaning regimen (n = 32). Their oral health-related quality of life (OHRQoL) was measured using the Taiwanese version of the Brief World Health Organization Quality of Life (WHOQOL-BREF) scale (general QoL) and the Oral Health Impact Profile (OHIP-14) (OHRQoL). Both scales were completed 14, 28, and 90 days after the initial assessment. The extent of PD in the experimental group was determined again at the end of the study.On the 28-item WHOQOL-BREF scale, the scores of the experimental group were higher than those of the control group on 5 items and the environmental domain at 14 days. There was a significant improvement in the experimental group on 2 items at 28 days and at 90 days after periodontal treatment (both P < .05). No difference was found between the 2 groups in score on the OHIP-14; however, there was a significant improvement in the experimental group in total score at 28 and 90 days after periodontal treatment (both P < .05). The number of teeth with probing depth ≥5 mm and the percentage of dental plaque were both significantly reduced after the intervention (both P < .001).Patients with a comprehensive plan for PD care showed some improvement in QoL, including in the environmental domain, and on the total score for OHRQoL. Comprehensive periodontal treatment also alleviated periodontal symptoms.

Oral-health-related quality of life of dental patients: a hospital based study in far north Queensland, Australia

OBJECTIVE

To investigate the prevalence, extent, and severity of oral-health-related quality of life among dental patients in far north Queensland, Australia.

METHODS

A questionnaire was designed consisting of two parts: socio-demographic questions and the short form of Oral Health Impact Profile (OHIP-14) in part 1 and 2 respectively. The survey was conducted from July to August 2014 among patients attending the James Cook University Dental Clinic.

RESULTS

Five hundred and nineteen questionnaires were distributed and collected. Of these, 40 were excluded from the analysis due to being incomplete. Therefore, a total of 479 questionnaires were available for the analysis. Half the respondents (50.9%) reported one or more of the 14 impacts as "fairly often" or "very often." The individual OHIP items with the highest prevalence recorded were physical pain and psychological discomfort. Females (52.2%) experienced a slightly higher prevalence compared to males (49.3%) but this difference was not statistically significant (Chi-square test: P > 0.05). Participants who identified as Indigenous Australian or Torres Strait Islanders and those in the 36-50 age group recorded the highest prevalence (Kruskal-Wallis test: P < 0.05). Indigenous Australians and Torres Strait Islanders also reported the highest mean extent score (4.39) and mean severity score (23.19).

CONCLUSION

This study revealed comparatively higher prevalence, extent, and severity scores reflecting a significantly poor oral-health-related quality of life among dental patients living in far north Queensland, Australia.

Oral health-related quality-of-life and mental health in individuals with chronic obstructive pulmonary disease (COPD)

OBJECTIVES

To investigate the association between oral health, oral health-related quality-of-life (OHRQoL) and mental health-related quality-of-life (QoL) in persons with chronic obstructive pulmonary disease (COPD) with respect to demographic, social and clinical oral health variables.

MATERIALS AND METHODS

One hundred participants were included in a cross-sectional study at a hospital in Norway. Data were collected via the Oral Health Impact Profile (OHIP-14), the SF-36v2 Health Survey Mental Component (MCS), other self-reported factors, an interview and a clinical examination. Multiple regression analyses were performed. The Regional Committee for Medical and Health Research Ethics approved the study. RESULTS. Higher education (p < 0.01), being a smoker (p < 0.05) and experience of oral health problems (p < 0.001) were significantly associated with oral health-related quality-of-life (OHRQoL). Furthermore, those with feelings of dry mouth (p < 0.05) and impaired OHRQoL (p < 0.001) experienced more mental health problems.

CONCLUSIONS

This study demonstrated that oral health and personal factors are related to mental health-related QoL and OHRQoL in individuals with COPD. This finding shows the need to focus on oral care.

Impact of rheumatic diseases on oral health and quality of life

OBJECTIVE

We investigated the effects of rheumatic diseases on oral symptoms, health habits, and quality of life in subjects with and without rheumatic diseases. The hypothesis was that patients with rheumatic diseases have more oral symptoms impairing their quality of life than healthy controls.

METHODS

A questionnaire was mailed to a random sample of 1500 members of the Finnish Rheumatism Association, including those with and without rheumatic diseases. We focused on symptoms of the mouth and temporomandibular area, and health habits. Oral Health Impact Profile (OHIP14) was used to evaluate the oral health-related quality of life. We analyzed differences between subjects with and without rheumatic diseases, controlled for age, gender, smoking, and non-rheumatic chronic diseases.

RESULTS

Completed questionnaires were received from 995 participants (response rate 66%). Of them, 564 reported rheumatic disease, 431 were used as controls. The patients reported significantly more all orofacial symptoms than controls. Severe dry mouth was reported by 19.6% of patients and 2.9% of controls (P < 0.001), and temporomandibular joint symptoms by 59.2% and 27.2% (P < 0.001), respectively. In the OHIP-14 questionnaire, the mean total score was significantly higher in patients (8.80 ± 11.15) than in controls (3.93 ± 6.60; P < 0.001).

CONCLUSION

The study hypothesis was confirmed by showing that the patients with rheumatic diseases reported oral discomfort and reduced quality of life more often when compared with controls.

Prevalence of persistent pain 3 to 5 years post primary root canal therapy and its impact on oral health-related quality of life: PEARL Network findings

INTRODUCTION

The frequency of persistent pain 3-5 years after primary root canal therapy and its impact on the patient's perceived oral health-related quality of life was determined in a practice-based research network.

METHODS

All patients presenting to participating network practices who received primary root canal therapy and restoration for a permanent tooth 3-5 years previously were invited to enroll. Persistent pain was defined as pain occurring spontaneously or elicited by percussion, palpation, or biting. The patient also completed an oral health-related quality of life questionnaire (Oral Health Impact Profile-14).

RESULTS

Sixty-four network practices enrolled 1323 patients; 13 were ineligible, 12 did not receive a final restoration, and 41 were extracted, leaving 1257 for analysis. The average time to follow-up was 3.9 ± 0.6 years. Five percent (63/1257) of the patients reported persistent pain, whereas 24 of 63 (38%) exhibited periapical pathosis and/or root fracture (odontogenic pain). No obvious odontogenic cause for persistent pain was found for 39 of 63 (62%). Teeth treated by specialists had a greater frequency of persistent pain than teeth treated by generalists (9.3% vs 3.0%, respectively; P < .0001). Sex, age, tooth type, type of dentist, and arch were not found to be associated with nonodontogenic persistent pain; however, ethnicity and a preoperative diagnosis of pulpitis without periapical pathosis were. Patients reporting pain with percussion tended to experience pain with other stimuli that negatively impacted quality of life including oral function and psychological discomfort and disability.

CONCLUSIONS

These results suggest that a small percentage (3.1%) of patients experience persistent pain not attributable to odontogenic causes 3-5 years after primary root canal therapy that may adversely impact their quality of life.

Changes in the oral health-related quality of life 24 h following insertion of fixed orthodontic appliances

Objectives:

The objective of this study was to assess changes in the oral health-related quality of life (OHRQoL) among patients wearing fixed orthodontic appliances 24 h after insertion.

Materials and Methods:

Sixty patients aged between 14 and 24 years (29 males and 31 females; mean age, 17.8 years; SD 3.1 years) were recruited from the Postgraduate Clinic, Department of Children's Dentistry and Orthodontics, Faculty of Dentistry, University of Malaya. The oral health-related quality of life (OHRQoL) was measured before treatment and 24 h after insertion of the orthodontic appliance. The instrument used to measure OHRQoL was a modified self-administered short version of Malaysian Oral Health Impact Profile (OHIP-16[M]) questionnaire. The higher the score, the poorer is the OHRQoL.

Results:

Overall score of OHRQoL increased significantly 24 h after insertion (mean 43.5±10.9) as compared to before insertion (mean 34.1±9.2) (P<0.001). Significant changes were found for the following items: Difficulties in chewing, bad breath, difficulties in pronunciation, discomfort in eating, ulcer, pain, avoidances of eating certain foods, difficulties in cleaning, embarrassment, avoid smiling, disturbed sleep, concentration affected, difficulty carrying out daily activities, and lack of self-confidence (P<0.05). Significant changes were also found in the mean difference of OHRQoL for gender (P<0.001).

Conclusion:

OHRQoL was found to deteriorate 24 h after insertion of fixed orthodontic appliances in almost all domains, with significant changes in gender. This information can be used as “informed consent”, which might increase patient's compliance as they are aware of what to expect from initial orthodontic treatment.

Measuring and decomposing oral health inequalities in an UK population

Objectives

With health inequalities high on the policy agenda, this study measures oral health inequalities in the UK.

Methods

We compare an objective clinical measure of oral health (number of natural teeth) with a self-reported measure of the impact of oral health (the Oral Health Impact Profile, OHIP) to establish whether the type of measure affects the scale of inequality measured. Gini coefficients and Concentration Indices (CIs) are calculated with subsequent decompositions using data from the 1998 UK Adult Dental Health Survey. Because the information on OHIP is only available on dentate individuals, analyses on the number of natural teeth are conducted for two samples – the entire sample and the sample with dentate individuals only, the latter to allow direct comparison with OHIP.

Results

We find considerable overall pure oral health inequalities (number of teeth: Gini = 0.68 (including edentate), Gini = 0.40 (excluding edentate); OHIP: Gini = 0.33) and income-related inequalities for both measures (number of teeth: CI = 0.35 (including edentate), CI = 0.15 (excluding edentate); OHIP: CI = 0.03), and the CI is generally higher for the number of teeth than for OHIP. There are differences across age groups, with CI increasing with age for the number of teeth (excluding edentate: 16–30 years: CI = 0.01, 65 + years: CI = 0.11; including edentate: 16–30 years: CI = 0.01, 65 + years: CI = 0.19). However, inequalities for OHIP were highest in the youngest age group (CI = 0.05). Number of teeth reflects the accumulation of damage over a lifetime, while OHIP records more immediate concerns.

Conclusions

There are considerable pure oral health inequalities and income-related oral health inequalities in the UK. Using sophisticated methods to measure oral health inequality, we have been able to compare inequality in oral health with inequality in general health. The results provide a benchmark for future comparisons but also indicate that the type of health measure may be of considerable significance in how we think about and measure oral health inequalities.

Cost-effectiveness of personalized plaque control for managing the gingival manifestations of oral lichen planus: a randomized controlled study

AIM

To undertake cost-effectiveness and cost-benefit analyses of an intervention to improve oral health in patients presenting with the gingival manifestations of oral lichen planus (OLP).

MATERIALS & METHODS

Eighty-two patients were recruited to a 20-week randomized controlled trial. The intervention was personalized plaque control comprising powered tooth brushing and inter-dental cleaning advice. The primary outcome measure was the oral health impact profile (OHIP) with secondary outcomes of pain, plaque index, mucosal disease score and cost-effectiveness. Private cost data and stated willingness-to-pay (WTP) values for treatment were obtained from intervention patients at 20 weeks.

RESULTS

Overall, 81% of intervention patients showed improvement in both plaque index and mucosal disease score at 20 weeks compared to 30% of controls that continued with their usual plaque control regimen. All intervention group patients stated a positive WTP value. The mean net value of the treatment was £172 compared to the incremental cost of the treatment estimated at £122.75. The cost-effectiveness analysis resulted in an incremental cost-effectiveness ratio of £13 per OHIP point.

CONCLUSIONS

The tailored plaque control programme was more effective than control in treating the gingival manifestations of oral lichen planus. The programme is cost effective for modest values placed on a point on the OHIP scale and patients generally valued the treatment in excess of the cost.

Happiness, subjective and objective oral health status, and oral health behaviors among Korean elders

OBJECTIVES

This study aims to comprehensively assess the association of subjective and objective oral health status and oral health behaviors with happiness, under consideration of demographic, socioeconomic, and general health-related factors. This study also aims to test whether subjective oral health outcomes are better predictors of happiness compared with objective oral health outcomes.

METHODS

The data were collected from 479 community-dwelling elders aged 65 years or over selected by a cluster sampling method. A questionnaire and an oral examination were implemented. A multiple regression method was conducted to assess associations with happiness index (HI).

RESULTS

The mean age of the elders was 74.6 years. Mean (standard deviation, SD) HI, EuroQol-visual analog scale (EQ-VAS) and 14-item oral health impact profile (OHIP-14) index were 5.7 (SD 2.3), 59.8 (SD 21.1), and 16.3 (SD 13.1). In the final model, a significant association with HI of the OHIP-14 index (P = 0.091) among all the participants and significant associations of oral symptoms (P = 0.038), wearing a removable denture (P = 0.039), and of the oral health behavior of daily toothbrushing (P = 0.007) among poorer oral health QoL group were confirmed under consideration of other related factors. While correlations of HI to subjective measures of health, EQ-VAS and OHIP-14 score were moderate to weak, those to objective measures of health were only weak or insignificant.

CONCLUSIONS

Oral impacts which might persistently affect one's daily life need to be considered in designing and delivering public services aimed to promote people's happiness. With oral health impacts and behaviors accounting for 10% of happiness among elders, public and community services for the elderly that support oral health and daily toothbrushing for the dentate are critical for the well-being of our elders.

Psychosocial aspects of temporomandibular disorders and oral health-related quality-of-life

OBJECTIVE

The aim of the study was to evaluate the association between psychosocial aspects of temporomandibular disorders (TMD) and oral health-related quality-of-life (OHRQoL) and, secondly, to investigate the gender differences in these associations using patient and non-patient groups.

MATERIALS AND METHODS

The sample of the study consisted of 79 patients with TMD and 70 non-patients. The data was collected by Finnish versions of the RDC/TMD Axis II profile and Oral Health Impact Profile (OHIP-14) questionnaires. The associations between Axis II profile sub-scales and OHIP prevalence were evaluated using chi-square tests, as stratified by group status (TMD patients and non-patient controls) and by gender. The association between OHIP prevalence and Axis II profile sub-scales were evaluated using logistic regression analysis, adjusted by age, gender and group.

RESULTS

OHIP prevalence (those reporting at least one problem) was 90.9% in the patient group and 33.3% in the non-patient group (p < 0.001, chi-squared test). OHIP prevalence was higher among those scoring higher on all RDC/TMD Axis II profile sub-scales, i.e. graded chronic pain status, depression and non-specific physical symptoms with pain items included and with pain items excluded. The associations were significant in the non-patient group. Women showed statistically significant associations of OHIP prevalence with all Axis II sub-scales. Among men, OHIP prevalence associated with GCPS and somatization. The logistic regression analysis showed that OHIP prevalence associated significantly with somatization and depression.

CONCLUSIONS

TMD associate with OHRQoL through multiple ways, linked with depression and somatization. These findings emphasize the importance of early and effective treatment of TMD.
