Evaluation of oral health-related quality-of-life in patients with generalized aggressive periodontitis

V, Sinha SP, Singh A, Karmakar S. Development and validation of a structured questionnaire to assess the Knowledge, Attitude and Practice (KAP) regarding the effect of yoga on periodontal health among Indian adults

Background

Periodontal disease is a chronic inflammatory disease of structures surrounding the teeth. Its etiology is multifactorial. The primary etiological factor is the microbial component; the other factors are systemic, behavioral, environmental, and psychological. Conventional management includes routine periodontal therapy involving prophylactic and surgical management. In developing countries like India, complementary medicine and alternative medicines like yoga are gaining popularity for improving systemic health. Hence this pilot study was designed to assess the psychometric properties of a structured questionnaire that can assess knowledge, attitude, and practice (KAP) regarding the impact of yoga on oral and periodontal health in Indian population.

Methods

The KAP questionnaire was developed (Stage One) using a deductive approach, and a psychometric evaluation of the questionnaire was performed to evaluate it's reliability and validity (Stage Two). Initial content validation and test re-test reliability were assessed using kappa statistics with binary responses. An intraclass correlation coefficient (ICC) was used to assess the questions in the practice and attitude category with categorical variables. Further assessment of psychometric properties of the questionnaire was done using item response theory. The developed questionnaire had four principal sections: demography of participants; knowledge regarding yoga and oral health; attitude towards yoga and oral health; and practice towards implementing yoga for oral health.

Results

The ICC for all the assessed questions was greater than 0.60 suggesting satisfactory stability. Internal consistency measured using Cronbach's alpha for knowledge, attitude, and practice items were reported to be 0.632, 0.923, and 0.591 respectively and that of the KAP total was 0.632.

Conclusions

The findings of this study showed that the questionnaire had an acceptable psychometric property for measuring KAP regarding yoga and it's role in oral and periodontal health among Indian adults. The analysis of participant responses revealed that they had a medium level of knowledge regarding yoga and periodontal disease.

The economic and societal impact of periodontal and peri-implant diseases

Periodontal and peri-implant diseases result from a chronic inflammatory response to dysbiotic microbial communities and are characterized by inflammation in the soft tissue and the ensuing progressive destruction of supporting bone, resulting in tooth or implant loss. These diseases' high prevalence, multifactorial etiology, extensive treatment costs, and significant detriment to patients' quality-of-life underscore their status as a critical public health burden. This review delineates the economic and sociocultural ramifications of periodontal and peri-implant diseases on patient welfare and healthcare economics. We delve into the implications of diagnosis, treatment, supportive care, and managing destructive tissue consequences, contrasting these aspects with healthy patients.

Validation of the Malay Oral Impacts on Daily Performances and Evaluation of Oral Health-Related Quality of Life in a Multi-Ethnic Urban Malaysian Population: A Cross-Sectional Study

Oral Impacts on Daily Performances (OIDP) can be used as a generic or condition-specific oral health-related quality of life (OHRQoL) instrument. It offers different contexts on how dental conditions affect OHRQoL. This cross-sectional study aimed to validate a newly translated Malay OIDP (OIDP-M), compare OHRQoL, decayed, missing, or filled teeth (DMFT) in Malaysians, and investigate factors associated with OHRQoL. A total of 368 Malaysians were surveyed and examined for DMFT. Short-form oral health impact profile-Malaysia [S-OHIP(M)] and OIDP-M were used to measure OHRQoL. The OIDP-M was tested for reliability and validity. DMFT, S-OHIP(M), and OIDP-M between ethnicities were compared. Associations between ethnicity, DMFT, S-OHIP(M), and OIDP-M of Malays and Chinese were evaluated through partial correlation. Malays and Chinese had more filled teeth and DMFT compared with Indians. Malays reported worse OHRQoL through S-OHIP(M). Decayed teeth were positively associated with S-OHIP(M), physical, psychological, social disabilities, and handicap. For OIDP-M, decayed teeth were positively associated with OIDP-M, working, and sleeping. Missing teeth and ethnicity were positively associated with eating and speaking. Filled teeth were negatively associated with cleaning teeth. The OIDP-M was reliable and valid for evaluating OHRQoL. There were differences in DMFT and OHRQoL between ethnicities. Ethnicity affects OHRQoL, where Malays experienced worse OHRQoL due to dental problems.

The Influence of Periodontal Disease on Oral Health Quality of Life in Patients with Cardiovascular Disease: A Cross-Sectional Observational Single-Center Study

Background and Objectives: Cardiovascular disease is a leading cause of global death with a rising prevalence and a heavy economic burden. Periodontal disease has been associated with cardiovascular diseases—including incident coronary heart disease, peripheral artery disease and ischemic stroke. The study evaluates the quality of life of patients with cardiovascular and periodontal disease from the point of view of oral health by using the short version of the Oral Health Impact Profile (OHIP-14) questionnaire. Materials and Methods: This study included a total of 221 patients (61.86 ± 15.03 years old) selected from the Emergency Hospital of Sibiu, Romania. The participants self-completed the OHIP-14 questionnaire and they benefited from an oral health examination conducted to assess the presence and the severity of periodontal disease. Results: Out of the 147 patients with cardiovascular disease, 77.5% had periodontal disease (32.6% stage I, 29.2% stage II, and 15.6% stage III and IV). The presence of periodontal disease was associated with a lower oral-health-related quality of life (p < 0.001, ANOVA) and with a higher OHIP-14 score in patients with cardiovascular disease (18.67 ± 8.17, p < 0.001 ANOVA). No significant difference was observed concerning patient sex and background; however, age, body mass index and the lack of an appropriate oral hygiene routine had a strong association with the individual quality of life. The general OHIP-14 score was higher in patients with periodontal disease and associated cardiovascular disease, the presence of both cardiovascular and periodontal disease being associated with a lower quality of life. Conclusions: By increasing the patients’ awareness to oral healthcare measures, better outcomes and improved oral-health-related quality of life could be observed.

Efficacy of tooth splinting and occlusal adjustment in patients with periodontitis exhibiting masticatory dysfunction: A systematic review

OBJECTIVE

To evaluate the efficacy of tooth splinting (TS) and occlusal adjustment (OA) compared to no TS or OA in patients with periodontitis exhibiting masticatory dysfunction.

MATERIAL

The primary outcome criterion was tooth loss (TL), and the secondary outcome parameters were change in probing pocket depth (PPD), change in clinical attachment level (CAL), tooth mobility (TM), and patient-reported outcome measures (PROMs). Literature search was performed on three electronic databases (from 01/1965 to 04/2021) and focused on clinical studies with at least 12 months follow-up.

RESULTS

From a total of 1515 publications, 51 articles were identified for full-text reading, of which 2 retrospective case series on TS with low risk of bias and 1 randomized and 2 prospective studies on OA with unclear risk of bias were included. For TS, synthesis of data showed that in 72 patients, 26 out of 311 teeth (weighted mean incidence of TL 8.4%) and 156 out of 1541 teeth with no TS (weighted mean incidence of TL 10.1%) were lost over 2 years following non-surgical periodontal therapy. The randomized controlled clinical trial (RCT) indicated CAL gain for teeth with OA compared to no OA. For the effect of OA on TL, PPD, and TM, heterogeneous data were retrieved from the included studies.

CONCLUSIONS

Within the limitations of this review and based on a low level of evidence, it is concluded that TS does not improve survival of mobile teeth in patients with advanced periodontitis. OA on teeth with mobility and/or premature contacts may lead to improved CAL, while the effect of OA on the remaining periodontal parameters remains unclear.

Determining the factors associated with oral health-related quality of life in Chinese elders: Findings from the fourth national survey

OBJECTIVE

The purpose of this study was to assess the associations between the self-reported oral health-related quality of life (OHRQoL) of older Chinese people and their socio-economic status and oral health using data collected in the 4th National Oral Health Survey.

METHODS

After multistage stratified cluster sampling, 4332 adults aged 65-74 years participated in the study. After a clinical examination, the participants completed a structured questionnaire. A Mandarin version of the General Oral Health Assessment Index (GOHAI) was included in the questionnaire. Clinical examinations were carried out using the criteria recommended by the World Health Organization. Multivariate analysis was used to evaluate the associations of the clinical and socio-demographic variables with the GOHAI scores of the participants.

RESULTS

The weighted mean (SE) GOHAI score was 51.6 (0.0). Female sex and having more than 10 missing teeth, unrestored tooth spaces, more than 10 decayed teeth and a periodontal pocket ≥6 mm were negatively associated with the GOHAI score, while having a higher education level and living in the Eastern region of China were positively associated with the GOHAI score.

CONCLUSION

After adjustment for confounders, the OHRQoL of older Chinese individuals was mainly affected by untreated dental caries and the loss of teeth. Older Chinese individuals who were male, had a higher education level, were from the Eastern region, had no unrestored tooth spaces or deep periodontal pockets and had fewer decayed or missing teeth had higher GOHAI scores, indicating better OHRQoL.

Evaluation of the effect of periodontitis on quality of life using Oral-Dental Health-Related Quality of Life-United Kingdom scale

OBJECTIVE

The aim of this study was to investigate the impact of periodontitis on oral health-related quality of life (OHQoL) using Oral-Dental Health-Related Quality of Life-United Kingdom (OHRQoL-UK) scale and evaluate the contributing factors.

METHODS

50 patients with untreated periodontitis and 50 individuals without periodontitis were enrolled in the study. All subjects received detailed periodontal examination. Plaque index (PI), gingival index (GI), probing depth (PD) and clinical attachment level (CAL) measurements were examined. OHRQoL was assessed by the Oral Health Quality of Life-United Kingdom (OHRQoL-UK) scale. Symptoms of periodontitis were monitored by visual analogue scale (VAS). Socio-demographic characteristics, medical history, smoking status, hygiene habits of the participants were recorded. This study is registered at ClinicalTrials.gov as NCT04240014.

RESULTS

Total OHRQoL-UK scores were 38.24±6.47 in periodontitis patients and 55.88±9.38 in non-periodontitis individuals (p < 0.001). The scores of all 4 parameters were significantly lower in patients with periodontitis compared to healthy individuals (p <0.001). Higher PI, GI, PD and CAL values were associated with extensive negative impacts of periodontitis on OHRQoL (p < 0.001). According to the results of linear regression analysis, only periodontitis was found to associate with OHRQoL. Periodontal disease reduces the total quality of life score by 15.087 (ß= -15.087; 95% CI = [(-18.934)-(-11.240)].

CONCLUSIONS

Individuals with periodontitis has diminished OHRQoL compared to healthy individuals.

The impact of splinting mobile mandibular incisors on Oral Health-Related Quality of Life-Preliminary observations from a randomized clinical trial

AIM

To compare the Oral Health-Related Quality of Life (OHRQoL) of patients with mobile mandibular incisors before and after full-mouth disinfection (FMD) with and without splinting.

MATERIAL AND METHODS

Thirty-four periodontitis patients with ≥1 mobile mandibular incisor (degree II/III) were randomly allocated to the test or control group. All patients received FMD and the test group additional splinting of teeth 33-43. OHRQoL was assessed before (BL) and 3 months after FMD (RE) using the Oral Health Impact Profile (OHIP)-14. Data were compared within and between the groups (Wilcoxon test/Mann-Whitney U test).

RESULTS

Twenty-eight patients (13 test group/15 control group) were re-evaluated. FMD led to a reduction of the mean probing pocket depth (PPD; in mm) (test group: BL-PPD 3.89 ± 1.03, RE-PPD 2.82 ± 0.53; control group: BL-PPD 3.58 ± 0.66, RE-PPD 2.77 ± 0.59; each p ≤ .001), the mean clinical attachment level (CAL; in mm) (test group: BL-CAL 5.22 ± 1.38, RE-CAL 4.79 ± 0.85; control group: BL-CAL 4.58 ± 1.10, RE-CAL 4.41 ± 0.96; each p ≤ .05), and the mean OHIP-14 summary scores (test group: BL-OHIP 21.7 ± 11.06, RE-OHIP 9.9 ± 8.96, p = .0046; control group: BL-OHIP 16.8 ± 8.27, RE-OHIP 11.7 ± 8.55; p = .0217). The reduction of the OHIP-G14 scores was considerably higher in the test group but statistically not significant (p = .080).

CONCLUSIONS

The results show a positive impact of non-surgical periodontal treatment on OHRQoL and a possible tendency for further improvement by splinting mobile mandibular incisors.

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.

Patient-based outcomes and quality of life

Patient-based outcomes complement clinical data with patients' self-evaluation of their physical, psychological, and social well-being, and as such facilitate clinical decision-making, assessing the quality of care provided, and evaluating practices and policies. Some validated generic oral health-related quality of life measures used in recent research indicated a high performance. There is a proportional relationship between the quality of life and periodontitis, ie, the higher the level of periodontitis, the poorer the oral health-related quality of life. This relationship is heightened by the presence of symptoms such as bleeding, halitosis, and mobility. On the other hand, periodontal treatment has demonstrated the capability to improve quality of life substantially. Future research should focus on questionnaires that are able to explain the interlinked pathways between periodontal conditions, approaches to treatment approaches, and patients' well-being. The acquisition of new knowledge in the field is essential for the whole community, as we treat people not millimeters.

An Evidence-Based Approach to Outcome Measurement in Oral and Dental Health Services: Oral Health-Related Quality of Life and Oral Health Impact

PURPOSE

The purpose of this study was to examine the Oral Health-Related Quality of Life (OHRQOL) and Oral Health Impact Profile (OHIP) of oral and dental health patients in terms of gender, educational status, and the reason for coming to the oral health center. Also, we investigated the relationships between OHRQOL and OHIP.

METHODS

This cross-sectional study was conducted and planned for dental patients in Turkey. OHRQOL-United Kingdom (OHRQOL-UK) and OHIP-14 were used for data collection. Descriptive statistics, correlation analysis, student t-tests, and ANOVA were used for data analyses.

RESULTS

Of 527 respondents, 62.8% were female, and 37.2% were male. One-hundred-forty-one (26.8%) participants were illiterate. Three-hundred-fifty-four (67.20%) dental patients had an elementary school degree. Only 32 (6.10%) participants graduated from college and bachelor programs. For dimensions of the OHIP-14 and OHRQOL-UK, we detected statistically significant differences in personal characteristics. We found that gender, marital status, age, education status, and reasons for coming to the hospital have a significant impact on OHRQOL and OHIP.

LINKING EVIDENCE TO ACTION

These results are expected to provide important evidence-based information to health managers and decision-makers in health planning and reimbursement policies. Clinicians and health managers should use OHIP, quality of life (QOL), and evidence-based practice to determine individual treatments and approaches to improve oral health. QOL is an outcome indicator in healthcare services and evidence-based practice. Measurements of evidence-based health outcomes in national health systems can be made, and global comparisons and policies in oral and dental health can be developed.

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.

Oral health status of children with mouth breathing due to adenotonsillar hypertrophy

OBJECTIVES

Mouth breathing is an important health problem, commonly encountered in children. In children, adeno-tonsillar hypertrophy is the main reason causing partial or complete upper airway obstruction and reduction in airflow. This study aimed to determine the oral health status of children aged 3-15 years, with mouth breathing who were due to have surgery for adeno-tonsillar hypertrophy and referred to the Department of Otorhinolaryngology at Children's Hospital of a University in Ankara, Turkey between January-July 2015.

METHODS

The approval of the Non-Interventional Clinical Researches Ethics Board of Hacettepe University and written informed consents from the parents were obtained. The parents completed a questionnaire before the surgery. The children were examined using dental mirror and explorer under dental unit lighting. Oral health status was evaluated with DMFT/S, dmft/s, ICDAS II, dental plaque and gingival indices. The chi-square test, Kruskal Wallis and Mann Whitney U tests were used to statistically analyse the results, with statistical significance p<0.05.

RESULTS

Of the 170 children who had adenotonsillar hypertrophy with mouth breathing, 150 the parents agreed to participate the study. 77 of the children (51.3%) were male; the mean age was 5.9 ± 2.6. Mean dmft was 3.8 ± 3.6, dmfs 9.7 ± 1.1, DMFT 0.4 ± 1.0 and DMFS 0.6 ± 1.5 respectively. Among the children, 101 (67.3%) had cavitated dental caries, and according to ICDAS II, none had healthy teeth, 15 (10.0%) had initial, 42 (28.0%) had moderate and 93 (62.0%) had advanced caries. Of the children, 89.3% had gingivitis and the proportion of gingivitis in posterior region was found to be significantly higher than anterior region (p < 0,001).

CONCLUSIONS

The oral health status of mouth breathing in children with adeno-tonsillar hypertrophy was poor. To reduce the risk of dental caries and periodontal disease among these children, regular dental follow-up and preventive programmes for oral health are needed.

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.

Dental anxiety and oral health-related quality of life in aggressive periodontitis patients

OBJECTIVES

To measure dental anxiety levels and oral health-related qualities of life (OHRQoL) in patients with aggressive periodontitis (AgP) compared to controls and analyze their association with various demographic and clinical parameters.

METHODS

Sixty consecutive patients with AgP were compared to 80 age- and sex-matched controls with no known history of periodontal disease. Collected data included demographics, smoking habits, numerical rating scale (NRS), Corah's Dental Anxiety Scale (DAS) and Oral Health Impact Profile-14 (OHIP-14), DMFT index (Decayed, Missing and Filled Teeth), Plaque Index (PI), probing depth (PD), bleeding on probing (BOP), and radiographic bone loss.

RESULTS

AgP patients exhibited statistically significant higher scores in the DAS total as well as sub-scores, except from DAS 1st question. Compared to the control group, AgP patients exhibited worse OHIP-14 global as well as in all individual OHIP-14 domains scores. Among both AgP and control patients, the physical pain domain was where the highest impact was recorded, while the lowest impact was recorded in the functional limitation domain.

CONCLUSIONS

AgP patients were positively associated with higher levels of dental anxiety and worse OHRQoL. Self-perception of dental anxiety and OHRQoL should be regarded as an integral element in routine diagnostic work-up process of periodontal diseases.

STATEMENT OF CLINICAL RELEVANCE

Aggressive periodontitis (AgP) patients exhibited higher dental anxiety levels and worse oral health-related quality of life (OHRQoL) compared to controls. Professionals should design strategies that will cope with the dental anxiety associated with the treatment and prevent decreases in OHRQoL.

Psychometric characteristics of the "General Oral Health Assessment Index (GOHAI) » in a French representative sample of patients with schizophrenia

BACKGROUND

The "General Oral Health Assessment Index" (GOHAI) was widely used in clinical or epidemiological studies worldwide, as it was available for use in different languages. Therefore, the aim of this study was to evaluate the psychometric characteristics of the GOHAI in a representative sample of patients with schizophrenia.

METHODS

A total of 90 schizophrenic patients (in-patients and out-patients) were recruited from the participants of the "buccodor study" (NCT02167724) between March and September 2015. They were selected using a random stratified sampling method according to their age, sex, or residential area (urban/rural area). GOHAI validity (construct, predictive, concurrent and known group validity) and internal consistency (reliability) were tested. Test-retest reliability was evaluated in 32 subjects.

RESULTS

The mean age was 47.34 (SD = 12.17). Internal consistency indicated excellent agreement, with a Cronbach's α value of 0.82 and average inter-item correlation of 0.65. Intraclass correlation coefficients for test-retest reliability with 95% confidence intervals were not significantly different (p > 0.05). Construct validity was supported by three factor that accounted for 60.94% of the variance observed. Predictive validity was corroborated as statistically significant differences were observed between a high GOHAI score, which was associated with self-perceived satisfaction with oral health, lower age and high frequency of toothbrushing. Concurrent validity was corroborated as statistically significant relationships were observed between the GOHAI scores and most objective measures of dental status. For known group validity, they was no significant difference of the mean GOHAI score between out or in-patients (p > 0.05).

CONCLUSION

Acceptable psychometric characteristics of the GOHAI could help caregivers to develop ways to improve the Oral Health related Quality Of Life of schizophrenic patients.

Immediate implant and rehabilitation based on All-on-4 concept in patients with generalized aggressive periodontitis: A medium-term prospective study

BACKGROUND

Aggressive periodontitis renders a great challenge to the conventional implant due to the risks of infection and ongoing marginal bone loss (MBL). A study about full-arch immediate implant and restoration in patients with advanced generalized aggressive periodontitis (GAP) was not read, even though the All-on-4 concept has been proven to be predictable for edentulous patients.

PURPOSE

This prospective study aimed to evaluate the feasibility and medium-term outcomes of immediate implant and rehabilitation based on the All-on-4 concept in patients with advanced GAP via clinical and radiographic analyses.

MATERIALS AND METHODS

Seventeen patients (mean age 39.4 years) with advanced GAP received immediate postextraction implant and rehabilitation based on the All-on-4 concept between January 2009 and January 2014. Eighty implants were inserted into 20 arches (7 maxillae and 13 mandibles). The average follow-up duration was 5 years (range 2-7). Complications, probing depth, and plaque, bleeding, and gingiva indices were evaluated. MBL was measured based on the panoramic radiographs taken immediately after surgery and annually thereafter.

RESULTS

The cumulative survival rate (CSR) of the implants was 98.75% (79/80) after an average of 5 years. One tilted implant failed due to peri-implantitis. The average peri-implant MBL was 0.8 ± 0.4 and 1.2 ± 0.3 mm after 1 and 7 years, respectively. The CSR was 100% (20/20) for definite prostheses, while 85% (17/20) for provisional prostheses. The average probing depth, and plaque, bleeding, and gingiva indices at the last recall visit were 3.0 ± 0.5, 1.2 ± 0.4, 0.5 ± 0.5, and 0.4 ± 0.4 mm, respectively. Patient showed high satisfaction to the overall effects.

CONCLUSIONS

Based on this study, the All-on-4 concept provided predictable outcomes in patients with GAP in 2- to 7-year follow-ups, and averted the severe bone defect area of aggressive periodontitis.

Impact of periodontal disease on quality of life: a systematic review

The diagnosis of periodontal disease is commonly based on objective evaluations of the patient's medical/dental history as well as clinical and radiographic examinations. However, periodontal disease should also be evaluated subjectively through measures that quantify its impact on oral health-related quality of life. The aim of this study was to evaluate the impact of periodontal disease on quality of life among adolescents, adults and older adults. A systematic search of the literature was performed for scientific articles published up to July 2015 using electronic databases and a manual search. Two independent reviewers performed the selection of the studies, extracted the data and assessed the methodological quality. Thirty-four cross-sectional studies involving any age group, except children, and the use of questionnaires for the assessment of the impact of periodontal disease on quality of life were included. Twenty-five studies demonstrated that periodontal disease was associated with a negative impact on quality of life, with severe periodontitis exerting the most significant impact by compromising aspects related to function and esthetics. Unlike periodontitis, gingivitis was associated with pain as well as difficulties performing oral hygiene and wearing dentures. Gingivitis was also negatively correlated with comfort. The results indicate that periodontal disease may exert an impact on quality of life of individuals, with greater severity of the disease related to greater impact. Longitudinal studies with representative samples are needed to ensure validity of the findings.

Study protocol: a cluster randomized controlled trial to assess the effectiveness of a therapeutic educational program in oral health for persons with schizophrenia

BACKGROUND

Schizophrenia is a severe mental disorder that affects 1 % of the world's population, including 600,000 people in France. Persons with schizophrenia (PWS) have excess mortality (their life expectancy is reduced by 20 %) and excess morbidity. In addition, such persons may have a large number of missing or decayed teeth. Dental caries and periodontal measurement indexes are often twice as high as the level found in the general population. Poor oral health can also affect quality of life and oral health is inseparable from general health. The management of oral health problems needs a multidisciplinary approach. According to the World Health Organization, the aim of therapeutic education (TE) is to help patients take care of themselves and to improve empowerment and recovery. In this educational approach, it is important to take into account the patient's personal experience. Though rarely investigated, the personal experience of PWS in oral health quality of life (OHRQoL) must be used to build a therapeutic educational programme in oral health (TEPOH) in a multidisciplinary approach, and the effectiveness of this program must be evaluated.

METHODS/DESIGN

We report the protocol of a randomized controlled cluster study. This study will be conducted in twelve hospitals in France. We hypothesized that a decrease of 20 % in the proportion of patients with CPI ≥ 3 would establish the effectiveness of TEPOH. Therefore, 12 hospitals will be randomly allocated to either TEPOH or no TEPOH. Altogether, they will have to recruit 230 PWS, who will be randomly allocated with a ratio of 1:1 to one of two conditions: control without intervention versus the group benefitting from TEPOH.

DISCUSSION

If successful, the study will generate methodologically sound results that provide knowledge on the effectiveness of a TEP in oral health for PWS. The results can be used to promote OHRQoL in a global health approach and develop appropriate strategies to encourage and facilitate financial support for healthcare, the multidisciplinary treatment of dental disorders, and the development of training in oral and mental health for caregivers.

The impacts of adenotonsillar hypertrophy on periodontal health in children: a prospective controlled pilot study

OBJECTIVES

To evaluate the impacts of obstructive adenotonsillar disease on periodontal health and to assess the efficacy of adenotonsillectomy in the prevention of chronic periodontitis in children.

METHODS

This prospective and controlled clinical study was conducted between August 2012 and February 2013 with 35 pediatric patients who had permanent anterior dentition. The study group included twenty patients (n = 20) who had complaints of chronic mouth breathing and snoring and were diagnosed with obstructive adenotonsillar disease. These patients underwent adenoidectomy with or without tonsillectomy. We performed periodontal examinations to assess the periodontal health status in these children before and two months after surgery. The periodontal measures included plaque index (PI), pocket depth (PD) and gingival index scores (GI). Subsequently, these periodontal measures were compared with healthy control group who had no adenotonsillar disease (n = 15).

RESULTS

Among the study group six patients underwent adenoidectomy and 14 patients underwent adenoidectomy combined with either tonsillectomy or tonsillotomy. The preoperative PI, PD and GI scores of the study group were 1.27 ± 0.39, 1.34 ± 0.31 and 0.97 ± 0.37 respectively. These scores were significantly higher compared to the control group (p < 0.001). These periodontal index scores were significantly improved after surgery (p = 0.008 for PI and p < 0.001 for both PD and GI). In addition, we found no difference in postoperative values of PD and GI between the study group and control group.

CONCLUSION

We concluded that obstructive adenotonsillar disease adversely affects periodontal health in children and surgical management of obstruction improves the clinical findings. However, more comprehensive research is required to elucidate the association between adenotonsillar hypertrophy and periodontal disease.
