Halitosis in young patients with chronic kidney disease: findings from a randomized controlled trial.

BACKGROUND: Chronic kidney disease (CKD) directly affects oral health. Yet data about halitosis in young CKD patients and the impact of dental prophylaxis is limited. Therefore, as part of this randomized clinical trial, halitosis in young CKD patients undergoing intensive or standard oral preventive procedures was to be explored. METHODS: Three volatile sulfur compounds (hydrogen sulfide, methyl mercaptan and dimethyl sulfide) were measured in 30 young patients with CKD (mean age 14.2 years; 16 males, 14 females). Breath samples were taken after 3 and 6 months and analyzed with selective gas chromatography (OralChroma). Tongue coating (Winkel Index) and clinical indices to determine local inflammation or oral hygiene (Papillary Bleeding Index and Quigley-Hein Index) were assessed. Within an extended anamnesis, patients and their mothers and nurses were questioned about the perceived halitosis. Corresponding quotes were noted verbatim. Patients were randomized to either intensive need-related oral health care measures (oral preventative program, OPP) or a one-stage standard prevention (treatment as usual, TAU). RESULTS: While there were no differences in volatile sulfur compound levels between TAU and OPP at the three time points of measurements (p > 0.05), there was a tendency towards a reduction in dimethyl sulfide and hydrogen sulfide of affected patients within the OPP group over time. Looking at potential differences between both groups with regard to tongue coating, significant differences were observed between baseline and 3 months after study start in the OPP group, and between baseline and 6 months after study start in the TAU group (p < 0.05). The burden of halitosis was frequently reported by patients' mothers and nurses. CONCLUSIONS: Young CKD patients regularly suffered from halitosis and dimethyl sulfide was its main source. Preventive measures mainly resulted in a reduction of tongue coating. TRIAL REGISTRATION: The German Clinical Trial Register (# DRKS00010580).

The tongue microbiome of young patients with chronic kidney disease and their healthy mothers.

OBJECTIVES: Oral microbiome plays a crucial role in the incidence and development of oral diseases. An altered intestinal microbiome has been reported in adults with chronic kidney disease (CKD). This study aimed to characterize the tongue microbiome of young patients with CKD compared to their healthy mothers to identify the influence of CKD-associated factors on resilient tongue ecosystem. MATERIAL AND METHODS: Thirty patients with CKD (mean age, 14.2 years; 16 males and 14 females) and generalized gingivitis were included in the study. Swabs of the posterior tongue were collected from the patients and 21 mothers (mean age 40.8 years). Next-generation sequencing of 16S rDNA genes was employed to quantitatively characterize microbial communities. RESULTS: The bacterial communities were similar in terms of richness and diversity between patients and mothers (p > 0.05). In patients with CKD, 5 core phyla, 20 core genera, and 12 core species were identified. CONCLUSIONS: The tongue microbiome of the study participants showed no relevant CKD-associated differences compared to their mothers and appears to be a highly preserved niche in the oral cavity. Differences observed in the abundance of individual species in this study could be attributed to the age rather than CKD, even after a mean disease duration of 11 years. CLINICAL RELEVANCE: CKD and its associated metabolic changes appear to have no detectable impact on the resilient tongue microbiome observed in young patients.

Third-party toothbrushing is associated with a positive patient experience: randomized, single-blind, patient-centered analysis.

BACKGROUND: As the need for care increases with higher age, so does the need for assistance with oral hygiene. A recent study analyzed the clinical effectiveness of oral hygiene assistance provided by caregivers. The current secondary analysis of this study aimed to assess pleasant and unpleasant perceptions of patients while being brushed and to investigate whether these perceptions depend on the qualification of the person brushing and the type of toothbrush used (manual vs. powered). METHODS: First, a qualitative study was conducted. This aimed at developing the questionnaire. Items were extracted on the basis of qualitative interviews with a sample of 6. A delphi process ensured the content validity of the final instrument. The main study comprised 39 periodontitis patients with reduced oral hygiene capability randomized to one of four groups: brushing carried out by trained laypeople or dental professionals, each using a manual or powered toothbrush at three different time points during anti-infective periodontal therapy. Patient perceptions of the third-party toothbrushing were assessed immediately after brushing. RESULTS: Patients reported mainly positive feelings regarding being brushed by a third person and the interaction with this person during brushing. Neither the professional background of the brushing person nor the type of brush had a significant influence on pleasant and unpleasant perceptions (all F < 3.30, all p > 0.07, all η2 < 0.10). CONCLUSIONS: Patient perceptions of third-party toothbrushing are mainly positive regarding wellbeing and interactions with the toothbrushing person, and do not depend on the qualification of the brushing person or the toothbrush used (manual versus powered).

Oil pulling to relieve medication-induced xerostomia: A randomized, single-blind, crossover trial.

OBJECTIVES: To determine the subjective effectiveness of oilpulling on medication-induced xerostomia with regard to symptom relief, quality of life, taste, mucosal moisture and oral parameters. MATERIALS AND METHODS: In a randomized, single-blind, crossover trial in participants with medication-induced xerostomia (n = 26; mean age 64.71 (standard deviation (SD) 15.60) years), we investigated oilpulling efficacy (sunflower oil) versus mineral water after one-week use. Xerostomic burden (visual analogue scale, VAS), symptom relief and oral examinations (gingivitis index, plaque index, whole stimulated and unstimulated salivation rates) were investigated at baseline and the end of the follow-up. RESULTS: Oilpulling reduced the xerostomic burden (baseline value 6.46 (SD 1.80), decreasing to 4.93 (SD 2.97)) (p = .003), without difference between oil versus water (p = .067). Baseline values for water were 6.08 (SD 2.17) decreasing to 5.72 (SD 2.17) (p = .124). Compared to water, oil made swallowing easier (p = .031), caused a pleasant mouthfeel (p = .031) and caused less waking up at night (p = .031). Effectiveness (p = .002) and duration (p = .007) of symptom relief showed differences between products in favour of oil. CONCLUSIONS: Oil pulling alleviated the overall xerostomic burden. In the comparison between oil and water, no difference regarding symptom relief could be shown. Patients should be informed of possibilities and limitations of oilpulling as inexpensive and easy-to-obtain alternative to commercially available products for short-term symptom relief.

Impact of care level, setting and accommodation costs on a newly developed oral care nursing plan format for elderly patients with care needs - Results from a cross-sectional study.

OBJECTIVES: A new oral care nursing plan format for improved communication among dentists, nursing staff and caregivers has been developed in Germany. We aimed to (1) describe this plan, (2) investigate the prevalence of oral health problems among elderly patients with care needs documented by the plan, outline the recommendations in the plans and (3) investigate whether the accommodation costs or care needs of patients influenced oral care quality or the need for oral hygiene support documented within the plan. METHODS: In this cross-sectional trial, oral care nursing plans were collected from outpatient and inpatient care clinics. Items on the oral care nursing plan were divided into three areas (oral health, oral hygiene needs, and coordination needs and dental therapy) and were correlated with the care level and accommodation costs. RESULTS: Oral care nursing plans were collected from seven dentists (N = 747; 94.5% from inpatient and 5.5% from outpatient care). The plans enabled documentation of well-known oral health and hygiene problems among elderly patients. In their current form, the plans provided recommendations for obvious oral hygiene tasks such as toothbrushing or fluoridating, rather than specialized tasks such as nutritional advice or dry mouth asymptomatic therapeutic approaches. Although accommodation costs were associated with the need for oral hygiene support (not with oral care condition), the care level influenced both measures. CONCLUSIONS: The oral care nursing plan can facilitate documentation of oral health and hygiene among elderly individuals with care needs. Further clarification of the plan would help promote careful documentation by dentists.

The impact of a needs-oriented dental prophylaxis program on bacteremia after toothbrushing and systemic inflammation in children, adolescents, and young adults with chronic kidney disease.

BACKGROUND: Chronic kidney disease (CKD) still leads to high mortality rates, mainly due to cardiovascular disease. One important influencing factor is persisting low-grade chronic inflammation partly maintained by gingivitis that favors transient bacteremia during daily activities such as toothbrushing. METHODS: To examine whether intensive dental prophylaxis can restore oral health, reduce the prevalence of bacteremia and degree of systemic inflammation indicated by CRP levels, we conducted this pilot study examining 30 CKD patients aged 6-26 years, 15 receiving intensive prophylaxis (IP), 15 receiving treatment as usual (TAU) serving as control group. There were three appointments for examination, each 10 ± 1 weeks apart (at baseline, after intervention periods one and two, when TAU also received IP, and the IP group stopped prophylaxis). RESULTS: The gingival index (GI) in the IP group decreased by 90% (GI 0.09; p=0.001), resulting in almost healthy gingiva. There was no significant change in CRP or prevalence of bacteremia. General prevalence of bacteremia after toothbrushing was 9.5% affecting 7 (26%) of the participants. In three participants, bacteremia dissolved after IP, in one after TAU. Two patients developed bacteremia ≥ 10 weeks after ending IP. We identified eight different bacterial species. CONCLUSIONS: We were able to show that IP can effectively treat gingivitis. It might be a promising approach to reduce systemic inflammation and subsequently lower premature cardiovascular disease, despite the lack of statistical significance. Future research requires a larger patient cohort to enable matched treatment groups with long-term follow-up and molecular detection methods for bacteremia.

Bacteraemia of oral origin in children-A Systematic review and network meta-analysis.

OBJECTIVES: To systematically review the prevalence of bacteraemia, triggered by dental intervention and home oral hygiene practices, in children. The network meta-analysis (NMA) quantitatively compared the risk of bacteraemia triggered by dental extractions and home and professional cleaning procedures. MATERIALS AND METHODS: Clinical trials with the outcome "bacteraemia in children" were searched. The NMA was performed using the frequentist weighted least-squares approach comparing the odds ratios (OR) of different interventions. RESULTS: Among 11 of 13 studies, dental treatment was performed under general anaesthesia. In 2,381 patients, bacteraemia occurred in 38.7%-56% patients following single-tooth extractions, in 22%-46% after manual toothbrushing (MTB), and in 26%-78% after power toothbrushing (PTB). When MTB was set as the reference (OR 1), rubber cup polishing showed a slightly higher risk (OR 1.26) of bacteraemia. PTB presented a higher risk (OR 1.79-2.27) than with single-tooth extractions (OR 1.55) but lower than that with multiple extractions (OR 2.55). CONCLUSION: Daily use of MTB and routine professional cleaning were associated with the lowest risk of developing bacteraemia in children with gingivitis, almost as much as with a single-tooth extractions. Improved plaque control with PTB increased the risk of bacteraemia. There is limited evidence on gingivitis-free and systemically-diseased children.

Impact of an interdisciplinary curriculum for dental students (GeriDent-Cologne) on attitudes and awareness towards older people and geriatric conditions.

INTRODUCTION: Training of dental students in the treatment of older patients must also consider the multiple chronic medical conditions that may be present. We developed an interdisciplinary gerodontology training curriculum for dental students (GeriDent-Cologne) to investigate its influence on the attitudes and expectancies of dental students towards the treatment of older patients. MATERIALS AND METHODS: The curriculum (given to fourth-year students) comprised five clinical examination stations that simulated different medical conditions affecting older people. Students were able to experience related issues first hand, express their fears and problems concerning dental treatment in older people and, through discussion with the supervisor, develop strategies to overcome these difficulties and enhance treatment. An extended version of the Los Angeles Geriatric Attitudes Scale was given to fourth- and fifth-year students (who acted as controls) over one semester. RESULTS: Dental students had a positive attitude towards older people, and their attitude did not change after attending the curriculum. However, participating in GeriDent-Cologne had a significant beneficial impact on the feeling of being prepared to treat older people, led to a significantly greater understanding of the impact of medical issues and resulted in a considerably higher level of geriatric clinical knowledge over time. CONCLUSIONS: GeriDent-Cologne led to positive and semester-long changes in awareness and knowledge of specific geriatric problems that influence dental treatment. We recommend the curriculum as a blueprint for the module of senior dentistry implemented in the new German dental licencing regulations.

Care need and dry mouth as risk indicators for impaired taste and smell.

To identify whether reduced saliva secretion or xerostomia symptoms are risk indicators for impaired taste and smell, depending on age and care needs. This cross-sectional study evaluated taste and smell in patients categorized into different age groups (<65> years) and different care need, with and without dry mouth. Of the 185 patients included, 119 were classified as "dry mouth" and 66 as "without dry mouth". Overall, 103 (55.7%) were female and 37 (20%) needed care. There was no difference between "dry mouth" and "without dry mouth" regarding identification of odors or tastes, but a difference in the number of correctly identified odors and tastes in favor of "without care need" patients (p < 0.05). The ability to identify smells and tastes was negatively influenced by age, number of medications, and number of comorbidities, but subjective dry mouth had no impact. According to our results, subjective dry mouth is not a risk factor for an impaired ability to recognize smells and tastes. However, care need representing age, the number of medications taken, and the number of chronic comorbidities is a risk indicator.

Effectiveness of brushing teeth in patients with reduced oral hygiene by laypeople: a randomized, controlled study.

BACKGROUND: To evaluate the success of plaque reduction after external toothbrushing by instructed laypeople versus dental professionals using either a manual or powered toothbrush. Longitudinal, randomized, parallel-group intervention study in periodontitis patients with reduced oral hygiene quality undergoing anti-infective therapy. Patients were randomly and equally assigned to one of four groups: laypeople using a manual or powered toothbrush or dental professionals using a manual or powered toothbrush. Plaque reduction (Quigley-Hein-Index (QHI), Marginal Plaque Index (MPI)), gingivitis (papilla bleeding index), and cleaning time (seconds) were investigated. RESULTS: Thirty-nine patients participated in the study. Neither the choice of toothbrush (p = 0.399) nor the use of a dental professional (p = 0.790) had a significant influence on plaque levels achieved. However, multivariate modeling indicated statistically significant differences in the external cleaning time between brushing groups, with longer time required by laypeople (p = 0.002) and longer use of the powered toothbrush (p = 0.024). CONCLUSION: When the ability to carry out personal oral hygiene is reduced, external brushing by dental professionals or instructed laypeople who meet previously defined criteria such as sufficient personal oral hygiene at home could help to fill the emerging dental care gap. A combination of oral hygiene approaches adapted to the individual needs of the patients in need of external help is necessary for optimum oral hygiene.

Impact of 0.1% octenidine mouthwash on plaque re-growth in healthy adults: a multi-center phase 3 randomized clinical trial.

OBJECTIVES: To investigate plaque inhibition of 0.1% octenidine mouthwash (OCT) vs. placebo over 5 days in the absence of mechanical plaque control. MATERIALS AND METHODS: For this randomized, placebo-controlled, double-blind, parallel group, multi-center phase 3 study, 201 healthy adults were recruited. After baseline recording of plaque index (PI) and gingival index (GI), collection of salivary samples, and dental prophylaxis, subjects were randomly assigned to OCT or placebo mouthwash in a 3:1 ratio. Rinsing was performed twice daily for 30 s. Colony forming units in saliva were determined before and after the first rinse. At day 5, PI, GI, and tooth discoloration index (DI) were assessed. Non-parametric van Elteren tests were applied with a significance level of p < 0.05. RESULTS: Treatment with OCT inhibited plaque formation more than treatment with placebo (PI: 0.36 vs. 1.29; p < 0.0001). OCT reduced GI (0.04 vs. placebo 0.00; p = 0.003) and salivary bacterial counts (2.73 vs. placebo 0.24 lgCFU/ml; p < 0.0001). Tooth discoloration was slightly higher under OCT (DI: 0.25 vs. placebo 0.00; p = 0.0011). Mild tongue staining and dysgeusia occurred. CONCLUSIONS: OCT 0.1% mouthwash inhibits plaque formation over 5 days. It therefore can be recommended when regular oral hygiene is temporarily compromised. CLINICAL RELEVANCE: When individual plaque control is compromised, rinsing with octenidine mouthwash is recommended to maintain healthy oral conditions while side effects are limited.

[Oral health assessment of seniors under outpatient care by family doctors : Development and validation of the geriatric outpatient oral health screening]. / Erfassung der Mundgesundheit von ambulant betreuten Senioren durch Hausärzte : Entwicklung und Validierung des geriatrischen ambulanten Mundgesundheits-Screenings.

BACKGROUND: Despite a high prevalence in the general practitioner (GP) and geriatric field, limitations of oral health of seniors under outpatient care in Germany are not routinely recorded. Since seniors with a high age visit GPs more often than dentists, the question arises whether an interdisciplinary screening instrument can be used to identify reduced oral health in routine practice. OBJECTIVE: The aim of the work was to develop a screening tool for reduced oral health for GPs and to validate this by dental examinations. MATERIAL AND METHODS: The geriatric outpatient oral health screening (GAMS) was developed as a subjective screening instrument to depict dental aspects relevant for geriatric patients, such as chewing problems, pain, periodontitis, bad breath or dry mouth in dichotomous questions. The urgency of a visit to the dentist is also assessed by the family doctor. A total of 75 patients were included and the GAMS and a dental examination were performed for validation. RESULTS: The subjective assessment of patients and dental findings showed reduced oral health especially with recognized risk factors for the development of systemic comorbidities, such as dysphagia and malnutrition, whereas oral health problems were underestimated by patients. Bites, chewing problems and dry mouth showed sufficient correspondence between dental findings and subjective assessment. CONCLUSION: The GAMS could help facilitate the consideration of oral health problems in geriatric patients in a GP setting and promote cooperation with dentists in the sense of European recommendations for action.

[Subjective oral health problems of geriatric outpatients and general medical geriatric findings-a pilot study]. / Subjektive Mundgesundheitsprobleme ambulant betreuter geriatrischer Patienten und allgemeinmedizinisch-geriatrische Befunde ­ eine Pilotstudie.

BACKGROUND: Oral health problems of the aged in Germany are not recorded in general practitioner's practices despite a high prevalence. For this purpose, a subjective geriatric outpatient oral health screening (GAMS) is available. AIM: The aim was to clarify whether subjective oral health problems reported by the GAMS can serve as risk indicators for medical findings in geriatric patients. MATERIAL AND METHODS: A total of 75 geriatric patients >75 years old in a family doctor's practice, GAMS, laboratory parameters, e.g. blood count with hemoglobin (g/dl), leukocytes (cells/nl), platelets (cells/nl), sodium (mmol/l), potassium (mmol/l), glucose in serum (mg/dl), HbA1c (HPLC)%, cholesterol (mg/dl) and glomerular filtration rate (GFR, ml/min), Barthel index and timed up and go test (TUG) were carried out. RESULTS: The most common oral health problems were chewing difficulties (19%) and xerostomia (40%). In the case of oral health problems, there were reduced everyday skills (p = 0.066), slower walking speed (0.049), higher serum glucose (p = 0.001) and long-term glucose values (p = 0.002). Bleeding gums are risk indicators for higher leukocyte concentration (p = 0.036). With xerostomia, the hemoglobin value drops by 1.13 g/dl (p = 0.001). DISCUSSION: The GAMS helps to identify oral problems as risk indicators of reduced geriatric health. Also, GAMS can be initiated in cases of the described geriatric pathologies in order to identify possible oral problems.

Does a pretreatment with a dentine hypersensitivity mouth-rinse compensate the pain caused by professional mechanical plaque removal? A single-blind randomized controlled clinical trial.

OBJECTIVES: Pain is affecting acceptance of supportive periodontal therapy and primary periodontitis prevention. Our objective was to evaluate the efficacy of a 1-week pre-treatment use of dentinal-hypersensitivity-reducing mouth-rinses (DHM) in periodontal maintenance (SPT) or dental prophylaxis patients. MATERIAL AND METHODS: One hundred fifty-five participants attending for professional mechanical plaque removal (PMPR) were randomly assigned to use a mouth-rinse twice daily for 1 week prior to their next PMPR. Rinses were containing either potassium oxalate (n = 52), arginine (n = 52), or herbal extracts (n = 51). At baseline and reassessment, procedural pain was assessed by visual analogue scale (VAS) and verbal rating scale (VRS). Self-reported efficacy was documented. RESULTS: No inter-group differences were estimated between both test groups and the control for baseline and reassessment means (VAS, VRS). In the SPT group, VAS reduction and self-reported efficacy were found (p < 0.05). CONCLUSION: The 1-week use of DHM failed to show a predictable effect on discomfort during PMPR overall. Around 20% of the patients showed a quantifiable benefit from both test mouth-rinses, whereas more than 50% reported a subjective pain reduction. Focusing patients undergoing supportive periodontal therapy, quantifiable effects were found for both test groups. From a patient's point of view, DHM might be a suitable adjunct to enhance procedural comfort, especially in patients with a history of periodontitis. CLINICAL RELEVANCE: The 1-week use of the dentinal-hypersensitivity-reducing mouth-rinses prior to professional-mechanical-plaque-removal showed to be a suitable adjunct to enhance procedural comfort during instrumentation, especially in patients undergoing supportive periodontal therapy. Registration number: DRKS00010811.

Objective masticatory efficiency and subjective quality of masticatory function among patients with periodontal disease.

AIMS: To examine patient-centred clinical outcomes for objective masticatory efficiency (OME) and subjective quality of masticatory function (QMF) among periodontitis patients using test methods easily applicable in daily practice. MATERIALS AND METHODS: Cross-sectional investigation of patients undergoing supportive periodontal therapy (n = 224). Outcomes included OME and QMF related to periodontitis characteristics. RESULTS: OME and QMF were associated (x2  = 0.252, p = 0.037) and showed highest values in stage 4 according to the new classification of periodontal disease. There were correlations particularly in stage 2 between OME and number of teeth (x2  = -0.317, p < 0.001), Quigley-Hein Index (x2  = 0.152, p = 0.031), attachment level (x2  = 0.268, p < 0.001), probing depths (x2  = 0.185, p = 0.006), tooth mobility (x2  = 0.147, p = 0.031) and functional occlusal units (x2  = -0.423, p < 0.001) but not bleeding on probing. A trend existed between QMF and number of teeth (x2  = -0.237, p = 0.050) and functional occlusal units (x2  = 0.238, p = 0.058), but not other periodontal findings. CONCLUSIONS: OME and QMF values represent each other and are highest in stage 4. Periodontitis findings influence masticatory efficiency particularly in stage 2, but gingival inflammation does not. Number of teeth and functional occlusal units are associated with QMF, while periodontitis findings have less impact. An assessment of mastication should be routinely included in the diagnosis of periodontitis patients in all stages.

The Underestimated Problem of Intra-Oral Halitosis in Dental Practice: An Expert Consensus Review.

Approximately 90% of halitosis cases originate within the oral cavity (intra-oral halitosis). With a focus on intra-oral halitosis, this narrative review article provides a current summary of the epidemiology, diagnosis and management of halitosis and discusses practical considerations for healthcare professionals (HCPs), including dentists, dental hygienists, general practitioners, community pharmacists, nurses and medical specialists. MEDLINE and PubMed were searched up to 31 December 2019. Additional information was sourced from reference lists of relevant published literature. Full-text articles which reported on the epidemiology, diagnosis and management of halitosis were considered for inclusion. Halitosis affects substantial numbers of individuals globally and is an underestimated problem in dental practice. Current estimates of the prevalence of halitosis, in addition to diagnostic methods and management considerations for halitosis, are discussed. Although not a life-threatening condition, halitosis has a significant impact on patients' quality of life and can result in psychological consequences including social, professional and affective limitations. Using a simple step-wise approach for diagnosis and treatment, dentists and dental hygienists are ideally placed to respond to an initial consultation for halitosis.

Impact of regular professional toothbrushing on oral health, related quality of life, and nutritional and cognitive status in nursing home residents.

OBJECTIVES: The oral hygiene of nursing home residents is poor. We aimed to investigate the efficacy of professional brushing using a specialized brush every three weeks and its impact on geriatric outcomes. METHODS: Nursing home residents received professional brushing with a three-headed brush by a dental nurse every three weeks for three months. Controls comprised subjects from an earlier investigation. Their general clinical, geriatric and oral health (number of teeth, periodontitis, Gingivitis Index, Plaque Index, Root Caries Index, Volpe-Manhold Index [VMI]) were investigated, and Geriatric Oral Health Assessment Index (GOHAI) was obtained before and after three months. RESULTS: Forty nursing home residents were included. Seventy-six percent of participants suffered from periodontitis, while 48% had partial and 20% total dentures. After three months, VMI had decreased vs baseline (P < .001). An improvement in nutritional status (P = .012) was found in residents with dementia after the intervention, as well as an improvement in the GOHAI (P = .031) in all participants. Gingivitis and plaque indices did not improve. CONCLUSIONS: The oral health of nursing home residents is poor for various reasons, and nursing home staff cannot fully address the increased oral hygiene risk with increasing multimorbidity. Professional brushing performed regularly by a dental nurse is an efficient method to improve oral hygiene in nursing home residents and may contribute to better nutritional status and quality of life. However, brushing every three weeks with a three-headed brush was not effective at improving gingivitis or plaque and was inferior to the two-week brushing interval with a manual toothbrush.

Do subjectively and objectively impaired oral health parameters influence geriatric assessment results in hospitalized geriatric patients?

BACKGROUND: Impaired oral health affects oral health-related quality of life (OHrQoL) in orthogeriatric hospitalized patients, and both might be associated with potential risk factors for functional impairment, based on the comprehensive geriatric assessment (CGA) and related blood laboratory values. As data on this field are scarce, we investigated possible associations between oral health, items of the geriatric oral health assessment instrument (GOHAI), CGA assessment tools, and relevant laboratory values. METHODS: Explorative cross-sectional pilot study investigating oral and general health, OHrQoL, and functionality based on objective oral health, GOHAI, CGA, and routinely assessed laboratory parameters of orthogeriatric patients. Correlations (Spearman's rho and Pearson's) and regression analysis were performed for the dependent variables functionality, cognition, Mini-Nutritional Assessment, Falls Efficacy Scale (FES), and the 15-item geriatric depression scale (GDS). RESULTS: Among all participants (N = 40), several GOHAI single items (GOHAI 1,4,5,7,10,11) correlated with certain CGA assessment results (fear of falling, Barthel index, handgrip power). Reduced subjective oral health (GOHAI, xerostomia) and objective oral health (oral hygiene index, root caries index, unstimulated salivation rate) correlated with reduced general health and CGA results (polypharmacy, handgrip power, FES, GDS). Anemia was seen in all participants, but no associations between reduced oral health and laboratory blood values were detected. CONCLUSION: Our results demonstrate the association between impaired subjective and objective oral health, OHrQoL, and physical functional impairment among orthogeriatric patients. Impaired GOHAI item results at the dentist, and the association between GOHAI values and CGA results that implies an association between physical and oral health, should encourage a geriatric check based on CGA, and vice versa. Results encourage interdisciplinary cooperation between geriatricians and dentists, but also indicate the need for further research in this field. TRIAL REGISTRATION: DRKS00013230.

Interdisciplinary assessment and management of a patient with a fibrous gingival enlargement of unknown origin: A case report.

A gingival enlargement of unclear cause could only be diagnosed after interdisciplinary cooperation as plasma cell gingivitis of unknown origin. Interdisciplinary approaches remain crucial when diagnosing rare gum diseases.
