- Aim: To assess whether oral health problems affect disease-specific quality of life (QoL) of inflammatory bowel disease (IBD) patients, and vice versa, whether IBD affects oral-health-related QoL.Materials and Methods: Individuals reporting IBD and matched controls were surveyed on general anamnestic information, oral-health-related questions and the Oral Health Impact Profile (OHIP)-5. IBD patients were additionally surveyed on years since diagnosis, disease activity and severity as well as health-related QoL (Short Inflammatory Bowel Disease Questionnaire, sIBDQ). OHIP-5 and sIBDQ were defined as primary outcome parameters, and several predictors and confounders were used in adjusted univariable and multivariable regression analyses.Results: Answers from 1108 IBD patients and 3429 controls were analysed. Compared with controls, IBD patients reported significantly more frequently an oral impact on daily life and worse oral-health-related QoL, with Crohn's disease (CD) patients being more severely affected than ulcerative colitis (UC) patients. The diagnosis of UC and CD, having <20 teeth, severe periodontitis and stressful daily-life experience were associated with a higher prevalence of poor oral-health-related QoL. Among IBD patients, an impaired IBD-specific, health-related QoL was significantly associated with the diagnosis of CD and depression, IBD activity and severity, having <20 teeth, presence of oral lesions and stressful daily-life experience, while a longer time since diagnosis was significantly associated with an improved IBD-specific, health-related QoL.Conclusions: The results of the present study indicate, for the first time, that oral health problems are associated with an impairment of IBD-specific health-related QoL, and vice versa, IBD is associated with an impaired oral health-related QoL. This emphasizes the potential advantages of including dental professionals in the multi-disciplinary treatment teams of IBD patients.

- Objectives: To assess, retrospectively, whether older age has an impact on implant osseointegration when compared with younger age. Methods: All patients ≥65 years old at implant installation, in an university setting over a time-period of 11.5 years, with complete anamnestic data and follow-up until prosthetic restoration were included and any early implant loss (EIL; i.e., lack of osseointegration prior to or at time-point of prosthetic restoration) was recorded. Further, one implant, from each of the elderly patients was attempted matched to one implant in a younger patient (35 to <55 years old at implant installation) from the same clinic based on: (1) gender, (2) implant region, (3) smoking status, and (4) bone grafting prior to/simultaneously with implant installation. The potential impact of various local and systemic factors on EIL in the entire elderly population, and in the matched elderly and younger patient group were statistically assessed. Results: Four-hundred-forty-four patients ≥65 years old (range 65.1-91.3; 56.8% female) receiving 1517 implants were identified; 10 patients had one EIL each (implant/patient level: 0.66/2.25%). Splitting this patient cohort additionally into 4 age groups [65-69.9 (n=213), 70-74.9 (n=111), 75-79.9 (n=80), ≥80 (n=40)] EIL was on the implant level 0.41, 0.83, 0.34, and 2.26%, respectively, (p=0.102) and on the patient level 1.41, 2.70, 1.25, and 7.50%, respectively, (p=0.104); multilevel analysis showed weak evidence of association of increasing age with higher EIL rate (p = 0.090). Matching was possible in 347 cases, and 5 (1.44%) and 9 (2.59%) EIL in the elderly and younger patients, respectively, were observed (p=0.280). EIL could not be associated with any systemic condition or medication intake. Conclusions: Elderly patients ≥65 years old presented a similarly low EIL rate as younger patients 35 to <55 years old, while patients ≥80 years old may have a slight tendency for a higher EIL rate. Hence, aging does not seem to compromise osseointegration, and if at all, then only slightly and at a later stage of life.

- Background: To describe the frequency and impact of oral lesions and professional dental care costs in patients with inflammatory bowel disease (IBD) (i.e., Crohn disease [CD] or ulcerative colitis [UC]) compared to matched controls).Methods: IBD patients and matched controls were surveyed on general anamnestic information, eating and drinking habits, and oral health- and dental care-related questions; IBD patients were additionally surveyed on oral lesions. Problems related to oral lesions and the amount of money spent for professional dental care in the past 12 months were defined as primary outcome parameters.Results: Answers from 1108 IBD patients and 3429 controls were analyzed. About 30% of the patients indicated having had problems with oral lesions, with CD patients having 46% higher odds and having them more often in a generalized form compared to UC patients. Further, self-reported severe periodontitis increased the odds of having oral lesions by almost 2.3-times. However, only about 12.5% of IBD patients were informed by their physician about oral lesions and about 10% indicated receiving treatment for them. Compared to controls, IBD patients required more often dental treatment and spent more money; specifically, UC and CD patients had 27 and 89% higher odds, respectively, for having spent ≥3000 DKK (ca. 440 USD) at the dentist compared to controls.Conclusions: IBD patients have more often oral health problems and higher expenses for professional dental care compared to matched controls. This included problems with IBD-related oral lesions, but these are rarely addressed by the medical or dental team.Keywords: Crohn disease; case-control studies; colitis; dental care; inflammatory bowel diseases; surveys and questionnaires; ulcerative.

- Aim: The aim of this questionnaire-based, case-control study was to assess whether self-reported oral health and periodontitis in ulcerative colitis (UC) and Crohn's disease (CD) patients differ from that in matched controls without inflammatory bowel disease (IBD).Methods: A survey including questions on general anamnestic information, IBD diagnosis, and oral health was distributed online. Self-perceived overall health of teeth and gums, severe periodontitis, and tooth loss were defined as outcome parameters.Results: Analyses were based on answers from 1108 IBD patients and 3429 controls. IBD patients reported significantly worse oral health and more periodontal problems compared to controls. Regression analyses corrected for relevant confounders showed for UC and CD patients significantly increased odds for fair or poor self-perceived overall health of teeth and gums (OR 2.147 and 2.736, respectively) and for severe periodontitis (OR 1.739 and 2.574, respectively) compared to controls; CD patients presented additionally 91% higher odds for having <20 remaining teeth.Conclusions: UC and CD patients have significantly increased odds for worse self-perceived oral health and severe periodontitis compared to controls, with CD patients being more severely affected and losing more teeth. It is strongly recommended that IBD patients are kept under close surveillance to prevent periodontitis development and/or mitigate its progression.

- Objectives To assess the effect of hyaluronic acid (HyA) application as adjunct to re-instrumentation of residual pockets in patients undergoing regular supportive periodontal care (SPC). Methods Chronic periodontitis patients (stage III and IV, grade B and C) with 4 interproximal residual pockets were randomly assigned to the test (HyA gel) or control (saline) group. After subgingival instrumentation, test or control substance was applied subgingivally, then daily supragingivally for 3 months, and if required a second time after subgingival re-instrumentation after 3 months. Clinical and patient reported outcome parameters were recorded every 3 months for 12 months. Pocket closure [probing pocket depth (PPD) <= 4mm with absence of bleeding on probing (BoP) at PPD = 4mm] was the main outcome parameter. Results Fifty-six patients (221 experimental sites) were analysed. Pocket closure was achieved in 56.8 and 46.6% of the experimental sites in the test and control group, respectively (p > 0.05), while median PPD and PPD distribution (< 5mm/5mm/ > 5mm) differed significantly between groups in favour of the test group, at 12 months. Further, significantly fewer sites in the HyA group required re-instrumentation at 3 months, and sites in the HyA group showed a tendency for lower odds to remain diseased compared to the control group (OR 0.48, 95%CI 0.22-1.06). The odds for a site to remain diseased after 12 months increased significantly in the presence of plaque (OR 7.94, 95%CI 4.12-15.28), but in general, decreased significantly over time (OR 0.48, 95%CI 0.28-0.81). Conclusion Re-instrumentation of residual pockets in SPC patients, per se, leads to a significant increase in pocket closure over time; this was impeded by poor plaque control. Repeated local application of HyA results in fewer sites requiring re-instrumentation and might slightly improve the rate of pocket closure. (clinicaltrials.gov registration nr. NCT04792541). Clinical relevance HyA gel is easy to apply, well accepted by patients, and may have some positive effect in terms of fewer sites requiring re-instrumentation at 3 months and higher pocket closure rate at 12 months.

- Objectives The present systematic review compared the effec- tiveness of soft tissue substitutes (STSs) and autogenous free gingival grafts (FGGs) in non-root-coverage procedures to increase keratinized tissue (KT) width around teeth. Materials and methods Included studies fulfilled the follow- ing main eligibility criteria: (a) preclinical in vivo or human controlled trials using FGG as control, (b) non-root-coverage procedures, and (c) assessment of KT width. Meta-analysis was performed on the gain in KT width (primary outcome variable) and several secondary variables. Results Eight human trials with short observation time evalu- ating five different STSs were identified. FGG yielded consis- tently significantly (p < 0.001) larger increase in KT width irrespective whether the comparison regarded an acellular ma- trix or a tissue-engineered STS. Further, FGG yielded consis- tently ≥2 mm KT width postoperatively, while use of STS did not, in the few studies reporting on this outcome. On the other hand, STSs resulted in significantly better aesthetic outcomes and received greater patient preference (p < 0.001). Conclusions Based on relatively limited evidence, in non- root-coverage procedures, FGG (1) resulted consistently in significantly larger increase in KT width compared to STS and (2) yielded consistently ≥2 mm KT width postoperatively, while STSs did not. STSs yielded significantly better aesthetic outcomes, received greater patient preference, and appeared safe. Clinical relevance Larger and more predictable increase in KT width is achieved with FGG, but STSs may be considered when aesthetics is important. Clinical studies reporting rele- vant posttreatment outcomes, e.g., postop KT width ≥2 mm, on the long-term (>6 months) are warranted.

- The cholesterol-lowering drugs, statins, possess anti-inflammatory, antimicrobial and pro-osteogenic properties, and thus have been tested as an adjunct to periodontal treatment. The present systematic review aimed to answer the following focused research question: What is the effect of local and/or systemic statin use on periodontal tissues in preclinical in vivo studies of experimentally induced periodontitis (EIP) and/or acute/chronified periodontal defect (ACP) models? A literature search (of Medline/PubMed, Embase/Ovid, CENTRAL/Ovid) using the following main eligibility criteria was performed: (i) English or German language; (ii) controlled preclinical in vivo trials; (iii) local and/or systemic statin use in EIP and/or ACP models; and (iv) quantitative evaluation of periodontal tissues (i.e., alveolar bone level/amount, attachment level, cementum formation, periodontal ligament formation). Sixteen studies in EIP models and 7 studies in ACP models evaluated simvastatin, atorvastatin or rosuvastatin. Thirteen of the EIP (81%) and 2 of the ACP (29%) studies presented significantly better results in terms of alveolar bone level/amount in favor of statins. Meta-analysis based on 14 EIP trials confirmed a significant benefit of local and systemic statin use (P < .001) in terms of alveolar bone level/amount; meta-regression revealed that statin type exhibited a significant effect (P = .014) in favor of atorvastatin. Three studies reported a significantly higher periodontal attachment level in favor of statin use (P < .001). Complete periodontal regeneration was never observed; furthermore, statins did not exert any apparent effect on cementum formation. Neither local nor systemic use of statins resulted in severe adverse effects. Statin use in periodontal indications has a positive effect on periodontal tissue parameters, supporting the positive results already observed in clinical trials. Nevertheless, not all statins available have been tested so far, and further research is needed to identify the maximum effective concentration/dose and optimal carrier.

- Objectives To evaluate the effect of local and/or systemic statin use as an adjunct to non-surgical and/or surgical periodontal therapy. Data Literature search according to PRISMA guidelines with the following eligibility criteria: (a) English or German language; (b) interventional studies; (c) statins as monotherapy or as an adjunct to non-surgical and/or surgical treatment of periodontitis; (d) clinical and/or radiographic treatment effect size of statin intake reported. Sources Medline (PubMed), Embase (Ovid), CENTRAL (Ovid). Study selection Thirteen clinical studies regarding local application and 2 with systemic administration of statins as an adjunct to non-surgical treatment (SRP) and 4 studies regarding intrasurgical statin application with a maximum follow-up of 9 months could be included; simvastatin, atorvastatin, and rosuvastatin were used. Local but not systemic statin application as an adjunct to SRP yielded significantly larger probing pocket depth (PD), radiographic defect depth (RDD), and bleeding index reduction, and larger clinical attachment level gain, and less residual PD and RDD (p≤0.016); rosuvastatin appeared as the most efficacious. Three of 4 studies reported a significant positive effect of intrasurgical statin application. No adverse events were reported after statin use. The vast majority of the included studies were from the same research group. Conclusions Significant additional clinical and radiographic improvements are obtained after local, but not systemic, statin use as an adjunct to SRP in deep pockets associated with intrabony defects and seemingly with furcation defects; intrasurgical statin application seems similarly beneficial. Confirmation of these results, and especially of the effect size, from other research groups is warranted.

- Aim: To assess the importance of achieving a successfully treated stable periodontitis patient status (PPS) during long-term supportive periodontal care (SPC).Methods: This retrospective cohort study included 100 periodontitis patients, who continued for ≥ 7.5 years after active periodontal treatment with SPC and were judged as overall adherent. The effect of various predictors on 3 patient-related outcome parameters was assessed: number of 1) diseased teeth at last SPC, 2) teeth lost due to periodontitis, and 3) teeth lost due to any reason.Results: One fifth of the patients were classified as stable after active periodontal treatment. After a mean follow-up of 10.77 years, 24 patients lost 38 teeth due to periodontitis. An unstable PPS and a higher number of diseased teeth per patient at first SPC, and inadequate oral hygiene levels over time significantly increased the risk for a higher number of diseased teeth per patient at last SPC and for more lost teeth due to periodontitis. However, high adherence to SPC appeared to mitigate the negative effect of an unstable PPS, especially regarding tooth loss due to periodontitis. Further, tooth loss due to any reason was about 3-times higher than tooth loss due to periodontitis and was affected by a larger number of predictors.Conclusions: Successfully treated patients with a stable PPS maintained a low number of diseased teeth and barely lost teeth during long-term SPC compared to patients not achieving a stable PPS after active periodontal therapy.

- Objectives: To assess whether in animals or patients with ≥ 1 tooth extracted, hyaluronic acid (HyA) application results in superior healing and/or improved complication management compared to any other treatment or no treatment.Materials and methods: Three databases were searched until April 2022. The most relevant eligibility criteria were (1) local application of HyA as adjunct to tooth extraction or as treatment of alveolar osteitis, and (2) reporting of clinical, radiographic, histological, or patient-reported data. New bone formation and/or quality were considered main outcome parameters in preclinical studies, while pain, swelling, and trismus were defined as main outcome parameters in clinical studies.Results: Five preclinical and 22 clinical studies (1062 patients at final evaluation) were included. In preclinical trials, HyA was applied into the extraction socket. Although a positive effect of HyA was seen in all individual studies on bone formation, this effect was not confirmed by meta-analysis. In clinical studies, HyA was applied into the extraction socket or used as spray or mouthwash. HyA application after non-surgical extraction of normally erupted teeth may have a positive effect on soft tissue healing. Based on meta-analyses, HyA application after surgical removal of lower third molars (LM3) resulted in significant reduction in pain perception 7 days postoperatively compared to either no additional wound manipulation or the application of a placebo/carrier. Early post-operative pain, trismus, and extent of swelling were unaffected.Conclusions: HyA application may have a positive effect in pain reduction after LM3 removal, but not after extraction of normally erupted teeth.Clinical relevance: HyA application may have a positive effect in pain reduction after surgical LM3 removal, but it does not seem to have any impact on other complications or after extraction of normally erupted teeth. Furthermore, it seems not to reduce post-extraction alveolar ridge modeling, even though preclinical studies show enhanced bone formation.
