A comparison of two questionnaires measuring oral health-related quality of life before and after dental hygiene treatment in patients with periodontal disease

Psychometric Properties of General Oral Health Assessment Index Across Ages: COSMIN Systematic Review

OBJECTIVES

To systematically review the psychometric properties of the Geriatric Oral Health Assessment Index (GOHAI) across age groups using the COnsensus-based Standards for the selection of health Measurement INstruments (COSMIN) methodology.

METHODS

Data: English peer-reviewed articles reporting studies of the development, translation, or validation of GOHAI.

SOURCES

PubMed, Web of Science, and EMBASE from Jan 1990 until December 31, 2023. Methodological evaluation: based on COSMIN methodology. The results are presented overall and for 4 age groups (≥60 years, all ages, <60 years, ≤45 years). Structural validity was summarized qualitatively. Internal consistency and reliability were synthesized via random-effects meta-analysis of T-transformed Cronbach α values, and Fisher's Z transformed correlation coefficients. Construct validity and responsiveness were assessed using effect sizes.

RESULTS

Four hundred ninety-seven records were identified, 72 underwent full-text assessment, resulting in 60 included reports. Structural validity was inconsistent across all age groups and overall. Internal consistency was sufficient with overall α = 0.81, and high evidence quality. Test-retest reliability was consistently sufficient across age groups with overall r = 0.84. For construct validity 361 hypotheses were assessed (37.4% for convergent-, 62.6% for known-groups validity). The percentage of confirmed hypotheses in ≥60-years, all ages, <60-years and ≤45-years were 75.5%, 66.7%, 78.9%, and 88.9%, respectively. Responsiveness was not assessed in the <60-years and ≤45-years age groups, leading to indeterminate overall rating with very low evidence quality.

CONCLUSIONS

This review affirms that GOHAI has sufficient psychometric properties as an oral health-related quality of life instrument in various age groups, but its responsiveness is scarcely researched and its utility for individual-level follow-up is limited. The measurement properties of oral health-related quality of life tools must be scrutinized in the changing demands of personalized and value-based dental care.

A scoping review of the economic impact of family oral health: Implications for public health, research, and policy

OBJECTIVES

To summarize evidence on the impact of oral health on individual and family economic outcomes, describe trends in the literature, and identify areas for additional research to inform public health research and practice.

METHODS

Searches were conducted within PubMed, CINAHL, EconLit, Cochrane Library, PsycInfo, and Web of Science databases. Article review, selection, abstraction, and reporting processes were guided by the Preferred Reporting Items for Systematic Reviews and Meta-Analyses Extension for Scoping Reviews.

RESULTS

Of 2758 unduplicated records identified, 52 met inclusion criteria. Study outcomes included indicators of employment/employability (n = 9), earnings/earnings potential (n = 26), parent missed work and family financial impacts of child oral health (n = 19), and financial loss (n = 3). Dental caries-related variables were the most common predictors of poorer economic outcomes. Other oral health problems, such as poorer dental functioning or poorer self-reported oral health status, also were associated with adverse economic outcomes. Significant associations with employment were found among studies that assessed interventions designed to improve oral health. Only one study estimated the impact of oral health on earnings. One-third of studies conducted multivariable analyses, and 14% incorporated race and ethnicity variables.

CONCLUSIONS

Although existing evidence suggests associations between oral health problems and poorer economic outcomes, there is a substantial need for more rigorous research to better understand the extent of economic impact of oral health problems and which populations are most affected. Additional high-quality research is needed to inform which interventions are most likely to improve oral health, reduce adverse economic impacts, and promote health and economic equity.

The oral health impact of dental hygiene and dental therapy populations: a systematic review

OBJECTIVES

Oral health-related quality of life (OHRQoL) is pivotal in patient care, reflecting oral health through dental patient-reported outcomes (dPROs). This systematic review aims to outline the 4-dimensional (4-D) impact of OHRQoL within patient populations routinely treated by dental hygiene and/or dental therapy providers, as there is limited literature present for these oral health care professionals.

METHODS

The study extracted and analyzed characteristics and multidimensional impact of OHRQoL, using the Oral Health Impact Profile (OHIP) as the primary dental patient-reported outcome measure (dPROM). The search strategy spanned 7 databases: Medline via the Ovid interface (Ovid MEDLINE(R) ALL), Embase via Ovid, Cinahl, APA PsycINFO via Ovid, Dentistry and Oral Sciences Search, Scopus, and Web of Science (Core Collection). It commenced September 2, 2022, with a refinement search on July 5, 2023. English language criteria yielded 645 articles postduplication removal. A screening procedure involving 3 reviewers encompassed title, abstract, and full-text review.

RESULTS

After application of inclusion and exclusion criteria, 5 articles were subjected to data extraction, capturing domain-specific information including baseline and follow-up OHRQoL data. An additional set of 13 articles containing summarized OHRQoL data underwent separate analysis. The Joanna Briggs Institute (JBI) critical appraisal tools were utilized for risk bias assessment of the included articles. The 4-D impact scores reported for baseline OHRQoL data, ranged from 3.10 to 4.20 for Oral Function, 0.84-2.70 for Orofacial Pain, 1.70-4.50 for Orofacial Appearance, and 0.44-2.50 for Psychosocial Impact. In follow-up OHRQoL data, the range for Oral Function was 1.52-3.60, Orofacial Pain 0.60-2.10, Orofacial Appearance 0.91-2.25, and Psychosocial Impact 0.10-0.60.

CONCLUSIONS

This review highlights a critical call for standardization in OHRQoL data collection for dental hygiene and dental therapy patient populations as only 26% of the predetermined distinct populations were found to have studies completed with 4-D impact of OHRQoL. Moreover, the presence of limited research in describing the multi-dimensional impact in patients routinely treated by these providers shows the urgency of substantive research in this area.

Dental anxiety and oral health-related quality of life before and after non-surgical periodontal treatment

OBJECTIVES

To (1) investigate dental anxiety (DA) and oral health-related quality of life (OHRQOL) before and after non-surgical periodontal treatment (NSPT) and (2) determine correlations between these patient-reported measures.

MATERIALS AND METHODS

Demographics, smoking habits, dental pain, Modified Corah's Dental Anxiety Scale (MDAS), and Oral Health Impact Profile (OHIP-14) were assessed in eighty-two participants.

RESULTS

Mean age was 48.3 years ± 11.5. At baseline, 8.5% reported being active smokers. Of non-smokers, 11% reported being an ex-smoker. After NSPT, 11.0% reported smoking. Patients' maximal pain in the last month decreased after therapy. Before treatment, participants reported higher DA. Extreme DA was observed in 8.5% of participants before therapy. Afterwards, 2.4% of participants reported extreme DA. Fear of having a foreign object in the mouth decreased after NSPT. All OHIP-14 scores, except functional limitation, improved post-treatment. Higher DA was associated with worse OHRQoL before treatment. After treatment, total MDAS score was associated with OHIP-14 global score, physical pain, psychological disability, and social disability. Worse MDAS sub-scores were associated with a higher OHIP-14 global score. Individuals with "normal/slight anxiety" had a significant improvement in OHRQoL, whereas people in the "moderate and extreme anxiety" group did not report a significant improvement. Patients diagnosed with generalized periodontitis (GP) stage III grade B and GP stage IV grade B reported less anxiety after NSPT.

CONCLUSIONS

Associations of MDAS subcategories with OHIP-14 domain scores were found before and after therapy. DA decreases and OHRQoL enhances after NSPT in patients with "normal/slight" anxiety to dental treatment. Dental practitioners should plan strategies to cope with anxiety to dental treatment and prevent decreases in OHRQoL.

CLINICAL RELEVANCE

Within the limitations of this study, DA and OHRQoL were positively correlated in patients with periodontitis, before and after NSPT, using the MDAS and OHIP-14 questionnaires. The results of our study suggest that treatment is effective in terms of alleviating DA and improving oral health, along with quality of life, in patients that report "normal/slight" anxiety to dental treatment. Nonetheless, results must be interpreted with caution since patients are generally anxious before any type of dental treatment. DA may not just be confined to NSPT per se. According to our results, evaluation of both outcomes should be an integral part of routine periodontal clinical evaluation and periodontal reevaluation of initial therapy. It is important that clinicians learn to identify patients that suffer from anxiety and take time to explain the treatment procedures to the patient, to strive for patient's emotional well-being before, during, and after dental care services. The use of specific questionnaires for both DA and OHRQoL may be more appropriate to demonstrate the psychological and quality of life differences due to periodontal disease and NSPT.

Synergy of Regenerative Periodontal Surgery and Orthodontics Improves Quality of Life of Patients with Stage IV Periodontitis: 24-Month Outcomes of a Multicenter RCT

In stage IV periodontitis patients with pathologic tooth migration (PTM), interdisciplinary treatment includes regenerative periodontal surgery (RPS) with an application of biomaterials and orthodontic therapy (OT) to restore function, esthetics and thereby quality of life (QoL). In a 24-month randomized trial we explored the synergy between regenerative medicine and biomechanical force application. The following methods were used: Forty-three patients had been randomized to a combined treatment comprising RPS and subsequent OT starting either 4 weeks (early OT) or 6 months (late OT) post-operatively. Clinical periodontal parameters and oral health-related QoL (GOHAI) were recorded up to 24 months. We obtained the following results: Mean clinical attachment gain (∆CAL ± SD) was significantly higher with early OT (5.96 ± 2.1 mm) versus late OT (4.65 ± 1.76 mm) (p = 0.034). Pocket closure (PPD ≤ 4 mm) was obtained in 91% of defects with early OT compared to 90% with late OT. GOHAI-scores decreased significantly from 26.1 ± 7.5 to 9.6 ± 4.7 (early OT) and 25.1 ± 7.1 to 12.7 ± 5.6 (late OT). Inconclusion, teeth severely compromised by intrabony defects and PTM can be treated successfully by RPS followed by early OT with the advantage of an overall reduced treatment time. As a result of the combined periodontal-orthodontic therapy, the oral health-related QoL of patients was significantly improved. Early stimulation of wound healing with orthodontic forces had a favorable impact on the outcomes of regenerative periodontal surgery.

EXISTING EVIDENCE FOR DENTAL HYGIENE AND DENTAL THERAPY INTERVENTIONS: A DETERMINATION OF DISTINCT PATIENT POPULATIONS

BACKGROUND

Dental patients seeking care expect to receive treatment options that are supported by evidence-based dental research based on dental patient-reported outcomes (dPROs). In dental hygiene and dental therapy, there is little usage of dPROs and dental patient-reported outcome measures (dPROMs) to assess the four-dimensions of oral health-related quality of life (OHRQoL). In order to assess the current evidence for dental hygiene and dental therapy interventions, the determination of distinct patient populations is essential.

AIMS

To determine patient populations that are clinically distinct groups of dental hygiene and dental therapy patients. To provide a preliminary literature search for a systematic review to identify interventions that provide four-dimensional oral health impact information for these patient populations.

METHODS

This narrative and methodological manuscript utilizes an allied dental expert panel consisting of two dental hygienists, two dental therapists, and a moderator to generate a list of clinically distinct patient populations within the scopes of dental hygiene and dental therapy. Additionally, a preliminary literature search utilizing PubMed was completed to assess the current research within the scopes of practice of dental hygiene and dental therapy that uses dPROs and dPROMs to assess the four-dimensions of OHRQoL. The patient population list generated by the allied dental expert panel and the patient populations from the articles identified in the preliminary literature search were compared to determine the needed and available evidence for dental hygiene and dental therapy interventions.

RESULTS

There were 19 distinct patient populations derived from the allied dental expert panel. Nine of the distinct patient populations were shared in the dental hygiene and dental therapy scopes of practice, six were specific to the dental hygiene scope of practice, and four were specific to the dental therapy scope of practice. From the preliminary literature search, five distinct patient populations had corresponding research. Of those, three distinct populations were shared between dental hygiene and dental therapy, and two were dental hygiene specific. There  : were no distinct patient populations found from the preliminary search specific to dental therapy.

CONCLUSION

There is a lack of research in the dental hygiene and dental therapy scopes of practice regarding utilization of dPROs and dPROMs to assess the four-dimensions of OHRQoL. In order to standardize the assessment of OHRQoL, the development of a list of distinct patient populations for dental hygiene and dental therapy interventions is essential. This initiative identifies which populations are lacking evidence and provides a pragmatic approach to conducting a systematic review to assess the four-dimensions of OHRQoL in the field of dental hygiene and dental therapy.

Evaluation of the Effect of Non-Surgical Periodontal Treatment on Oral Health-Related Quality of Life in Patients with Periodontitis at Different Stages

Collapse

The impact on the quality of life caused by the early loss of primary molars

INTRODUCTION

Evidence regarding the impact of early loss of primary molars (ELPM) on Oral Health-Related Quality of Life (OHRQoL) is lacking. The aim of the present study was evaluating the impact of ELPM on OHRQoL of Brazilian schoolchildren aged 6-10 years.

METHODS

This observational prospective cohort study was conducted with 163 schoolchildren, assigned in the primary tooth loss group (PTLG), in which all tooth loss was caused by carious lesions, and in a control group without tooth loss (CG). Two calibrated examiners conducted the clinical oral assessments to determine caries experience and tooth loss. OHRQoL was assessed using the Child Perception Questionnaire 8-10 years (CPQ8-10) instrument administered at baseline and at 10-12 months of follow-up.

RESULTS

Children in PTLG exhibited significantly more negative impact on OHRQoL at baseline (p < 0.01) than CG, and also after the follow-up period (p < 0.01). It was also possible to observe a significant reduction in the negative impact on OHRQoL in both CG and PTLG in the longitudinal analysis (p < 0.01). Nevertheless, there was an even more substantial reduction in the negative impact on OHRQoL in children in PTLG.

CONCLUSIONS

This study provides evidence that early tooth loss is associated with negative impact on OHRQoL. Moreover, it indicates that access to dental treatment can have a positive impact on the OHRQoL of children with dental caries and ELPM.

Patient-reported experiences and outcomes following two different approaches for non-surgical periodontal treatment: a randomized field study

Context

The current report is part of a prospective, multi-center, two-arm, quasi-randomized field study focusing on the effectiveness in general praxis of evidence-based procedures in the non-surgical treatment of patients with periodontitis.

Objective

The specific aims were to (i) evaluate patient-reported experience and outcome measures of treatment following a guided approach to periodontal infection control (GPIC) compared to conventional non-surgical therapy (CNST) and to (ii) identify potential predictors of subjective treatment outcomes and patient’s adherence to self-performed infection control, i.e. adequate oral hygiene.

Methods

The study sample consisted of 494 patients treated per protocol with questionnaire- and clinical data at baseline and 6-months. The GPIC approach (test) comprised patient education for adequate oral hygiene prior to a single session of full-mouth ultra-sonic instrumentation, while the CNST approach (control) comprised education and instrumentation (scaling and root planing) integrated at required number of consecutive appointments. Clinical examinations and treatment were performed by Dental Hygienists, i.e. not blinded. Data were processed with bivariate statistics for comparison between treatment groups and with multiple regression models to identify potential predictors of subjective and clinical outcomes. The primary clinical outcome was gingival bleeding scores.

Results

No substantial differences were found between the two treatment approaches regarding patient-reported experiences or outcomes of therapy. Patients’ experiences of definitely being involved in therapy decisions was a significant predictor for a desirable subjective and clinical outcome in terms of; (i) that oral health was considered as much improved after therapy compared to how it was before, (ii) that the treatment definitively had been worth the cost and efforts, and (iii) adherence to self-performed periodontal infection control. In addition, to be a current smoker counteracted patients’ satisfaction with oral health outcome, while gingival bleeding scores at baseline predicted clinical outcome in terms of bleeding scores at 6-months.

Conclusions

The results suggest that there are no differences with regard to patient-reported experiences and outcomes of therapy following a GPIC approach to periodontal infection control versus CNST. Patients’ experiences of being involved in therapy decisions seem to be an important factor for satisfaction with care and for adherence to self-performed periodontal infection control.

Effect of periodontal treatment on oral health-related quality of life - A randomised controlled trial

Objectives

Periodontal disease is a chronic, infectious gum disease, which eventually leads to tooth loss, adversely affecting quality of life (QoL). Most of the research in this area focuses on evaluating clinical parameters rather than patient-based outcomes. Currently, these parameters are gaining importance along with treatment outcomes of chronic diseases and QoL. This study evaluates the impact of periodontal disease and its treatment on oral health-related quality of life (OHRQoL).

Methods

We recruited 90 participants who were divided into two groups. One was the test group (n = 45) that underwent non-surgical periodontal therapy (NSPT) followed by periodontal flap surgery (SurgPT). Second was the control group (n = 45) that underwent only NSPT. Clinical parameters, plaque index, gingival index, periodontal/probing pocket depth (PPD), clinical attachment level (CAL), and mobility were recorded. An OHRQoL questionnaire was used to assess the functional, physical, social, and psychological domains at baseline, three, and six months.

Results

The mean PPD in the test group was 6.9 ± 0.38, 3.2 ± 0.36, 3.5 ± 0.5, and 5.8 ± 0.67, 3.13 ± 0.21, 3.73 ± 0.45 in the NSPT group at baseline, 3, and 6 months, respectively. The mean CAL in the SurgPT group was 7.07 ± 0.41, 3.56 ± 0.27, 3.74 ± 0.30, and 6.08 ± 0.16, 4.02 ± 0.17, 4.16 ± 0.19 in the NSPT group at baseline, 3, and 6 months, respectively. Both treatments resulted in reduction in all clinical parameters and were statistically significant in the SurgPT group (p < 0.001). Oral Health Impact Profile scores substantially decreased in the SurgPT group (mean difference-25.0) compared to the NSPT group (mean difference-5.0) (p-0.001).

Conclusions

In this study, NSPT and SurgPT had a positive impact on OHRQoL by improving clinical parameters, but SurgPT had substantially better outcomes in terms of improved QoL.

Periodontal therapy on the oral health-related quality of life of obese and non-obese individuals

Oral diseases such as periodontitis can have a more negative influence on the quality of life of obese than in normal-weight patients. The objective of the present study was to assess the impact of one-stage full-mouth disinfection (OSFMD) therapy on the oral health-related quality of life (OHRQL) of obese and non-obese individuals with periodontitis. Fifty-five obese and thirty-nine non-obese patients were evaluated. The questionnaires oral impacts on daily performance (OIDP) and oral health and quality of life (OHQoL) were given to all patients at baseline and 6 months after periodontal treatment by the OSFMD protocol. For statistical analysis, Chi-square, the two-factor repeated-measures ANOVA, and correlation tests were used. At baseline, mean global OHQoL and OIDP scores were similar for both groups (p > 0.05). At 6 months, OSFMD resulted in OHQoL and OIDP global scores improvements in both groups (p < 0.05), with no significant difference between groups. The most impaired activity at baseline was eating and cleaning teeth for both groups. Periodontal parameters were associated with worse values in the OHQoL and OIDP questionnaires only in obese patients. In conclusion, OSFMD yielded similar improvements in overall OHRQL in both obese and non-obese individuals. Periodontal parameters were associated with a worse quality of life in obese patients. Periodontal treatment can be an important component to improve the OHRQL of obese individuals, and clinicians should expect similar results as those obtained with non-obese patients.

The use of Oral Health Impact on Daily Living (OHIDL) transition scale in measuring the change in oral health-related quality of life among older adults

Background

This longitudinal study aimed to evaluate the longitudinal validity and reliability of the Oral Health Impact on Daily Living (OHIDL) transition scale and measure the perceived change in oral health-related quality of life (OHRQoL) after dental treatments among older adults.

Methods

OHIDL was administered to older adults who sought dental treatments. Participants were asked to assess changes in impact for each OHIDL item retrospectively compared with that before the treatment. The responsiveness, minimal clinically important difference (MCID), internal consistency and test–retest reliability of the OHIDL transition scale were evaluated. Multiple linear regression was employed to predict the change in oral health impacts after dental treatment. Beta coefficients (β) and 95% confidence intervals (CI) were reported.

Results

One hundred and seventy-six participants were followed-up with upon completing their dental treatments. The follow-up rate was 70.4% (176/250). The OHIDL transition score strongly correlated with the global rating of change (r_s = 0.76, P < 0.01). MCID was determined by participants who reported “a little improved” in the perceived oral health impacts, and their mean transition score was 3.3. Cronbach’s alpha of the transition scale was 0.87, and many items had a test–retest correlation of at least 0.60. Patients who perceived more oral health impacts at baseline as measured by the total intensity score (β = 0.32, 95% CI: 0.20, 0.44, P < 0.001) and those who had received endodontic treatment (β = 8.04, 95% CI: 4.36, 11.71, P < 0.001) would have more improvement in perceived oral health impacts.

Conclusions

The OHIDL transition scale has good psychometric properties and is sensitive to change over time. After receiving dental treatment, most of the study’s older adults perceived a lower intensity of OHIDL.

Clinical relevance

The OHIDL transition scale is a valid and reliable instrument to measure the change in OHRQoL after dental treatments.

Endpoints of active periodontal therapy

Aim

Position paper on endpoints of active periodontal therapy for designing treatment guidelines. The question was as follows: How are, for an individual patient, commonly applied periodontal probing measures—recorded after active periodontal therapy—related to (a) stability of clinical attachment level, (b) tooth survival, (c) need for re‐treatment or (d) oral health‐related quality of life.

Methods

A literature search was conducted in Ovid MEDLINE(R) and Epub Ahead of Print, In‐Process & Other Non‐Indexed Citations and Daily <1946 to 07 June 2019>.

Results

A total of 94 papers were retrieved. From the literature search, it was found that periodontitis patients with a low proportion of deep residual pockets after active periodontal therapy are more likely to have stability of clinical attachment level over a follow‐up time of ≥1 year. Other supporting literature confirms this finding and additionally reports, at the patient level, that probing pocket depths ≥6 mm and bleeding on probing scores ≥30% are risks for tooth loss. There is lack of evidence that periodontal probing measures after completion of active periodontal treatment are tangible to the patient.

Conclusions

Based on literature and biological plausibility, it is reasonable to state that periodontitis patients with a low proportion of residual periodontal pockets and little inflammation are more likely to have stability of clinical attachment levels and less tooth loss over time. Guidelines for periodontal therapy should take into consideration (a) long‐term tangible patient outcomes, (b) that shallow pockets (≤4 mm) without bleeding on probing in patients with <30% bleeding sites are the best guarantee for the patient for stability of his/her periodontal attachment, (c) patient heterogeneity and patient changes in immune response over time, and (d) that treatment strategies include lifestyle changes of the patient. Long‐term large population‐based and practice‐based studies on the efficacy of periodontal therapies including both clinical and patient‐reported outcomes (PROs) need to be initiated, which include the understanding that periodontitis is a complex disease with variation of inflammatory responses due to environment, (epi)genetics, lifestyle and ageing. Involving people living with periodontitis as co‐researchers in the design of these studies would also help to improve their relevance.

Periodontal disease and quality of life: Umbrella review of systematic reviews

This umbrella review appraised existing systematic reviews and meta-analysis to establish the impact of periodontal disease and therapy on general and oral health-related quality of life. A systematic electronic literature search was carried out in accordance with the PRISMA guideline up to January 2020 using PubMed, LIVIVO, EMBASE and OpenGrey (PROSPERO CRD 42020163831). Hand searching was performed through the reference lists of periodontal textbooks and related journals. All English language-based systematic reviews and meta-analysis that assessed the impact of periodontal disease and treatment interventions on general and oral health-related quality of life were included. Overall, eight articles met the inclusion criteria and their methodological quality was assessed using the AMSTAR2 criteria. Two systematic reviews showed a significant impact of oral conditions on general health-related quality of life, although the specific impact of periodontal disease remains inconclusive. Three systematic reviews established a negative impact of periodontal disease on oral health-related quality of life. Another three systematic reviews concluded that periodontal treatment can improve oral health-related quality of life. Oral conditions, like periodontal disease, can impact the general health-related quality of life. Periodontal disease is negatively correlated with oral health-related quality of life, although treatment interventions can improve self-reported quality of life. In view of the heterogeneity of generic instruments currently utilized to assess the self-reported quality of life of periodontal patients, the development of a general and oral health-related quality of life instrument specific for periodontal disease is strongly recommended.

Non-surgical periodontal therapy effectively improves patient-reported outcomes: A systematic review

AIM

Modern lifespan oral health research focuses on understanding the impact of periodontitis (or therapy) on clinical and patient-based outcome measures to provide effective care, improve patient safety according to the quality standards. For better targeted intervention and effective disease management, this systematically review aimed to investigate the relationship between non-surgical periodontal therapy and patient-based outcomes using OHIP-14.

METHODS

Seven Databases were searched for studies on patient-based outcomes responses to periodontal treatment. The time-period defined from search was from January 1977 to January 2019. Two independent reviewers carried out data search, selection of studies, data extraction and quality assessment using Mixed Method Appraisal Tool. Prospective cohort studies, intervention studies and observational studies written in English demonstrating non-surgical periodontal therapy response on the patient-reported outcomes (using Oral Health Impact Profile 14) were included in the review.

RESULTS

Thirteen studies were included in the review, which comprised of three randomised control trials, nine case series, and one was a quasi-experimental study. Eleven out of the 13 studies reported significant improvement in OHIP-14 scores amongst participants who had undergone non-surgical periodontal therapy. Physical disability, psychological discomfort and functional limitation were domains that improved significantly after non-surgical periodontal therapy in these studies. Physical pain was a common finding in short-term follow-up but improved significantly in long-term follow-up studies.

CONCLUSION

Based on clinical and patient-based outcomes measurement, it is recommended that non-surgical periodontal therapy is a "gold standard" approach towards improving patient-based outcomes, reducing co-morbidities and enhancing patient safely immediately and in long term.

The impact of nonsurgical periodontal treatment on oral health-related quality of life: a systematic review and meta-analysis

OBJECTIVE

To estimate the impact of nonsurgical periodontal treatment (NSPT) on patients' oral health-related quality of life (OHRQoL). The focused question for this systematic review was: in adults patients with periodontitis, does NSPT improve oral health-related quality of life?

MATERIAL AND METHODS

Five databases (PubMed, CIHNL, EMBASE, LILACS and CENTRAL) were searched up to April 2019 (PROSPERO CRD42018103393). Intervention trials and cohort studies assessing the OHRQoL data of adults with periodontitis, enduring non-surgical periodontal treatment (NSPT) were eligible for inclusion. Subgroup random-effects meta-analysis was conducted methodically.

RESULTS

Overall, 491 studies were retrieved, out of which 19 met the inclusion criteria. Two randomized clinical trials (RCTs) and ten cohort studies were further analysed. Seven cohort studies were included in the statistical analysis. Subgroup meta-analyses of cohort studies revealed that NSPT improves in average 2.49 (95% CI 0.95-4.02), 8.94 (95% CI 6.89-10.99) and 6.49 (95% CI 5.11-7.88) OHRQoL levels at 1-2 weeks, 3-4 weeks and 6-12 weeks of post-treatment, respectively.

CONCLUSIONS

NSPT procedures greatly improve the oral health-related quality of life within a short time, remaining stable after 3 months of treatment.

CLINICAL RELEVANCE

This systematic review brings forward summary evidence that NSPT improves the OHRQoL in adults with periodontitis from a patient-centred perception and remain stable in the short term.

Impact of One-Stage Full Mouth Disinfection and Periodontal Surgery on Oral Health-Related Quality of Life

Statement of the Problem

Information on patient-centered outcomes of periodontal disease and the impact of different periodontal treatment phases on the life quality of periodontal patients is limited.

Purpose

This study sought to compare patients' perception of their oral health-related quality of life (OHQoL) following one-stage full mouth disinfection (OSFMD) and surgical periodontal treatment.

Materials and Method

A pre-and post-interventional study design was conducted in two phases on a single group of patients. Subjects were recruited from moderate to severe chronic periodontitis patients referred to a private clinic. At baseline and after each treatment phase, periodontal parameters were recorded by a blind examiner. Patients received OSFMD, followed by periodontal flap surgeries and completed the validated Iranian version of the OHIP-49 questionnaire (OHIP-35-IR) at three time points (baseline, two weeks post-initial therapy and after completion of surgical phase). Data were analyzed using repeated measure ANOVA, paired and independent t-tests, and multivariate regression analysis by SPSS software version 21.

Results

38 patients (14 men, 24 women, mean age 40.30±11.93) completed the study. Periodontal parameters showed progressive improvement from baseline to the end of the study (p< 0.05). The total mean OHIP-35-IR score at baseline (89.25±19.26) was significantly improved (reduced) compared to each treatment phase (75.63±17.15 and 74.22±15.46, respectively; p< 0.001), with no significant difference between treatments. Improvements in subdomains of psychological discomfort, functional limitation, physical pain, and handicap accounted for the changes. The effect size was calculated to be 0.80 for the first and 0.66 for the second treatment phases.

Conclusion

Within limits, OSFMD and periodontal surgical treatment have positive impacts on the OHQoL of patients. Intensive periodontal non-surgical treatment is as effective as surgical intervention for achieving desirable patient-centered outcomes.

Periodontal Regenerative Therapy Using Enamel Matrix Derivative in Patient with Chronic Periodontitis: a 3-year 6-month Follow-up Report

Here, we report a case of chronic periodontitis requiring periodontal regenerative therapy. The patient was a 73-year-old man who visited Tokyo Dental College Suidobashi Hospital with the chief complaint of gingival swelling and mobile tooth in the mandibular incisor region. An initial examination revealed that 33% of sites had a probing depth (PD) of≥4 mm and 27% bleeding on probing. Radiographic examination revealed bone resorption extending as far as the root apex in #32 and 47, vertical bone resorption in #37, and horizontal resorption in other regions. Based on a clinical diagnosis of moderate chronic periodontitis, initial periodontal therapy was carried out followed by periodontal surgery. The patient's oral health-related quality of life was also assessed at the time of each periodontal assessment. Surgical periodontal therapy was subsequently performed at selected sites. Periodontal regenerative therapy using enamel matrix derivative was performed on #37. Other sites with a PD of ≥4 mm were treated with open flap debridement, and scaling and root planing. Following reevaluation, the patient was placed on supportive periodontal therapy. The patient's periodontal condition has remained stable over a 3-year 6-month period. The patient's oral health-related quality of life showed a marked improvement after periodontal therapy.

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.

Novel PAradigm to improve Inflammatory burden in end stage Renal disease (rePAIR): study protocol for a randomized controlled trial

Background

Given the importance of inflammation as a predictor of poor outcomes in End Stage Renal Disease (ESRD), reductions in inflammatory biomarkers have been proposed as a critical target in this population. This study targets chronic periodontitis, an oral inflammatory disease of microbial etiology causing persistent inflammation in ESRD. Unlike the previously reported episodic periodontal interventions, we propose to control periodontal inflammation with a continuous maintenance and oral health behavior modifications. We hypothesize that this strategy will improve systemic inflammation and oxidative stress, oral health and quality of life within the 6-month observation period.

Methods

The rePAIR (novel PAradigm to improve Inflammatory burden in ESRD) study is a pilot and feasibility, parallel-arm, and randomized controlled clinical trial that will recruit 72 ESRD subjects with periodontitis in a model of computerized block randomization. This trial aims to compare the effect of standard-of-care vs. repeated non-surgical periodontal therapy on systemic and oral inflammatory burden. This trial will recruit ESRD adult patients with periodontitis older than 21 years old with a minimum of 12 teeth and no history of periodontal treatment within a year. The trial will examine serum C-reactive protein (CRP) (primary outcome) as a biomarker of inflammation as well as interleukin-6 (IL-6), F2 isofurans and F2 isoprostanes (secondary outcomes) and compare their difference between groups from baseline to 6 months. The trial will also compare the difference between groups in patient-centered and clinical oral outcomes from baseline to 6 months.

Discussion

The trial follows a rigorous and transparent study design capturing elements such as pre-specified eligibility criteria, pre-specified primary and secondary outcomes, detailed intervention description to allow replication, intervention random allocation and concealment, blinding in outcome assessment, appropriate sample size calculations, explanation of interim analysis, as per CONSORT Guidelines. Further, gender diversity is secured not only at recruitment but also throughout the trial and during the analysis. Therefore, treatment response outcomes will be examined per gender category. In order to manage anticipated problems, the protocol has included alternative approaches.

A Comparison of Impact of Chronic Periodontal Diseases and Nonsurgical Periodontal Therapy on Oral Health-Related Quality of Life

Objectives

To evaluate the impact of chronic periodontal diseases (PDs) and compare phases of nonsurgical periodontal therapy (NSPT) on oral health-related quality of life (OHRQoL) in patients attending a tertiary care center of eastern Nepal.

Materials and Methods

Matched for socioeconomic status, participants were recruited in two groups: moderate-to-severe chronic periodontitis (n = 24, 43 ± 46 years) and chronic gingivitis (n = 25, 30 ± 96 years). The treatment modalities were scaling and root surface debridement (RSD) and supragingival scaling, respectively. The impact of periodontal disease treatment status was assessed by a self-reported questionnaire of Nepali Oral Health Impact Profile (OHIP-14) at baseline and 9–12 weeks after NSPT.

Results

The median (IQR) OHIP-14 total scores for PDs reduced from 7 (3–11) to 3 (1–7.5) after NSPT. Both groups showed a significant improvement on OHRQoL (p value < 0.001). The periodontitis group showed an increased median (IQR) reduction of 52% (35.22–86.15) compared with the gingivitis group with 27% (0.00–50.00). The impact on orofacial pain, orofacial appearance, and psychosocial dimensions was observed, which improved after NSPT in both groups.

Conclusion

PDs are directly associated with OHRQoL and treatment of the disease may enhance quality of life from a patient's perspective. Scaling and RSD provided better influence on OHRQoL than supragingival scaling.

Impact of maxillary sinus augmentation on oral health-related quality of life

BACKGROUND

The aim of this study was to measure the oral health-related quality of life (OHRQoL) after maxillary sinus augmentation to determine the physical and psychological impact of this procedure for the patient.

METHODS

Three hundred sixteen patients treated with an external or internal maxillary sinus augmentation and a total of 863 implants in the Department of Oral and Maxillofacial Surgery, Johannes Gutenberg University, Mainz, Germany, between July 2002 and December 2007 were included in this retrospective study. Total implant survival was assessed. Completion of a modified 26-item version of the Oral Health Impact Profile (OHIP-G) for assessing the oral health-related quality of life before and after the treatment was asked for. Subcategories were (1) functional limitations, (2) physical and psychological disabilities, and (3) complaints due to the surgical procedure. In 53 patients available for clinical follow-up examination, assessment of soft tissue parameters was performed.

RESULTS

After an average time in situ of 41.2 ± 27 months (3.4 years), the in situ rate was 95.4%. One-year survival rate and five-year survival rate according to Kaplan Meier were 95.4 and 94.4%. Concerning functional limitations, significant better values for OHRQoL after sinus augmentation procedure than before the treatment (p < 0.001) were seen. In the subcategory physical and psychological disabilities, all questions had significant better values after the sinus lift (p < 0.001). Concerning complaints due to the surgical procedure, mean total scores were 5.1 ± 5.4 pre-operative, 6.9 ± 6.1 (0-31) post-operative, and 2.4 ± 3.7 recently. This meant a significant difference between "pre-operative" vs. "post-operative" (p = 0.003), "pre-operative" vs. "recently" (p < 0.001), and "post-operative" vs. "recently" (p < 0.001). Concerning the influence of implant indication, edentulous patients showed the most distinct improvement after the procedure. Clinical assessment showed stable soft tissue parameters.

CONCLUSIONS

Evaluation of OHRQoL after sinus augmentation showed a significant improvement indicating a remarkable benefit for the patients through this procedure.

Longitudinal evaluation of the impact of dental caries treatment on oral health-related quality of life among schoolchildren

This study aimed to evaluate the impact of dental caries treatment on oral health-related quality of life (OHRQoL) among schoolchildren and the responsiveness of the Child Perceptions Questionnaire (CPQ8-10 ) instrument. Brazilian schoolchildren, 8-10 yr of age, were randomly selected and assigned to two groups--dental caries treatment (DCT) and caries-free (CF)--according to their caries experience [decayed, missing, or filled primary teeth (dmft) and decayed, missing or filled secondary teeth (DMFT) values of ≥ 0]. The CPQ8-10 instrument was administered at baseline and at 4 wk of follow-up (i.e. 4 wk after completion of dental treatment). In the DCT group, increases in CPQ8-10 scores were observed between the baseline and follow-up results. However, longitudinal evaluation of the CF group demonstrated no statistically significant difference in CPQ8-10 scores. Responsiveness of the CPQ8-10 instrument (magnitude of change in CPQ8-10 scores) in the DCT group was greater (effect size >0.7) than in the CF group. The findings of this study show that dental caries treatment has an important impact on OHRQoL of children. The CPQ8-10 was considered an acceptable instrument for longitudinal measurement of changes in OHRQoL.

Impact of chronic periodontitis on quality-of-life and on the level of blood metabolic markers

CONTEXT

Despite the recognition that systemic factors can alter the risk to the chronic periodontitis (CP), only recently has evidence begun to emerge, still under investigation, that infections of the oral cavity are related with low quality-of-life (QoL) and are able to influence the occurrence and severity of certain conditions and systemic diseases.

AIMS

The aim of this study was to evaluate the impact of CP on the QoL and on the metabolic systemic condition of CP patients.

SETTINGS AND DESIGNS

Cross-sectional, case-controlled, age- and gender-matched study.

SUBJECTS AND METHODS

Quality-of-life assessment (Functional Assessment of Chronic Illness Therapy-Fatigue), periodontal examinations and blood tests were obtained from 20 CP patients and 20 age- and gender-matched healthy controls (HC).

STATISTICAL ANALYSIS USED

parametric paired t-test for numerical data (metabolic parameters) and nonparametric paired Wilcoxon signed rank test to compare the QoL ordinal data of both groups. Statistical significance was determined at the 0.05 level.

RESULTS

Healthy controls had fewer negative impacts in all QoL areas studied. CP patients showed higher levels of low-density lipoprotein cholesterol, glucose, and uric acid compared with the HC.

CONCLUSIONS

Chronic periodontitis negatively affected the overall well-being and systemic condition of a group of Brazilian individuals.

Socioeconomic and family influences on dental treatment needs among Brazilian underprivileged schoolchildren participating in a dental health program

BACKGROUND

The objective of this study was to compare the socioeconomic and family characteristics of underprivileged schoolchildren with and without curative dental needs participating in a dental health program.

METHODS

A random sample of 1411 of 8-to-10 year-old Brazilian schoolchildren was examined and two sample groups were included in the cross-sectional study: 544 presented curative dental needs and the other 867 schoolchildren were without curative dental needs. The schoolchildren were examined for the presence of caries lesions using the DMFT index and their parents were asked to answer questions about socioenvironmental characteristics of their families. Logistic regression models were adjusted estimating the Odds Ratios (OR), their 95% confidence intervals (CI), and significance levels.

RESULTS

After adjusting for potential confounders, it was found that families earning more than one Brazilian minimum wage, having fewer than four residents in the house, families living in homes owned by them, and children living with both biological parents were protective factors for the presence of dental caries, and consequently, curative dental needs.

CONCLUSIONS

Socioeconomic status and family structure influences the curative dental needs of children from underprivileged communities. In this sense, dental health programs should plan and implement strategic efforts to reduce inequities in oral health status and access to oral health services of vulnerable schoolchildren and their families.
