Abstract
Susceptibility to periodontal disease depends on individual factors within the host response to the bacterial challenge. The study of these factors requires longitudinal studies of an undisturbed development of the disease process. On the basis of the original longitudinal studies on the natural histology of periodontal disease staged in Sri Lanka and Oslo/Norway, several analyses of periodontal parameters and tooth status have been performed. The main findings were that in the first 20 years of complete absence of oral hygiene practices or preventive services attachment was lost at various rates. Three groups of subjects could be identified: rapidly progressing (RP) (8%), moderately progressing (MP) (81%), and subjects with no disease progression (NP) (11%). In the second two decades, the RP subjects have lost most of their teeth and no NP patients were identified anymore. The progression rate in these two decades was much slower, and the tooth mortality decreased. It could be predicted that subjects who had lost more than 2 mm at age 30 would not maintain a functional dentition at age 60. The corresponding control population in Oslo was used to study the influence of gingival inflammation on the initiation and progression of periodontal disease. The pattern and rates of attachment loss were identified in a population that was exposed to optimal and regular preventive services from age 3 onward. In the observation period of 26 years, it could be demonstrated that gingival inflammation varied little throughout adult life and always bleeding sites occurred consistently in 10% to 20%. The role of ongoing gingivitis in the pathogenesis of attachment loss was identified and also reflected stability whenever it was absent. Tooth mortality was only found in subjects with ongoing gingivitis. After 50 years of tooth age, 63% of the teeth were still maintained, while 99.8% were maintained after 50 years when gingival inflammation had been absent. Consequently, continuous gingivitis represented a risk factor for tooth loss.

Abstract
BACKGROUND Periodontitis is an inflammatory condition initiated by oral bacteria and is associated with several systemic diseases. Quercetin is an anti-inflammatory and anti-bacterial poly-phenol present in various foods. The aim of this meta-analysis was the evaluation of the effects of quercetin administration in animal models of experimental periodontitis. METHODS A systematic search was performed in electronic databases using the following search terms: "periodontitis" or "periodontal disease" or "gingivitis" and "quercetin" or "cyanidanol" or "sophoretin" or "pentahydroxyflavone". In vivo preclinical animal models of experimental periodontal disease with a measurement of alveolar bone loss were included in the analysis. The risk of bias of the included studies was assessed using the SYRCLE tool. RESULTS The systematic search yielded 335 results. Five studies were included, four of them qualified for a meta-analysis. The meta-analysis showed that quercetin administration decreased alveolar bone loss (τ2 = 0.31, 1.88 mm 95%CI: 1.09, 2.67) in experimental periodontal disease animal models. However, the risk of bias assessment indicated that four SYRCLE domains had a high risk of bias. CONCLUSIONS Quercetin diminishes periodontal bone loss and prevents disease progression in animal models of experimental periodontal disease. Quercetin might facilitate periodontal tissue hemostasis by reducing senescent cells, decreasing oxidative stress via SIRT1-induced autophagy, limiting inflammation, and fostering an oral bacterial microenvironment of symbiotic microbiota associated with oral health. Future research will show whether and how the promising preclinical results can be translated into the clinical treatment of periodontal disease.

Abstract
INTRODUCTION Communication training has become an essential part of the dental curriculum. The aim of this study was to evaluate the communication curriculum developed and introduced 2016-2021 at the University of Bern, School of Dental Medicine (SDM), Switzerland. MATERIALS AND METHODS The curriculum was implemented cumulatively in three phases: (1) lectures and accompanying role plays, (2) forum theatre and trainer-based communication training and (3) self-assessment. Students were surveyed 2016-2021 at the end of each semester using anonymous online questionnaires with five-point Likert scales (0-4). RESULTS A total of 191 fourth- and fifth-year students were surveyed, and 165 (86.4%) questionnaires were analysed. The mean age of the participants was 24.2 ± 1.4 and 45.5% were female. While students' opinions about the need to communicate increased during weekly lectures in phase 1, their opinions about their ability to communicate simultaneously decreased. During phase 2, fourth-year students' opinions on the need to communicate with dental patients increased from 3.22 ± 0.61 to 3.73 ± 0.45 (p = .001), anticipated benefits for dentists increased from 2.78 ± 0.71 to 3.43 ± 0.57 (p = .001) and for patients from 3.00 ± 0.76 to 3.47 ± 0.63 (p = .022). Only in phase 3, opinions on the ability to communicate statistically significantly increased for both fourth- (2.34 ± 0.71 to 2.72 ± 0.60, p = .033) and fifth-year (2.20 ± 0.63 to 2.86 ± 0.59, p = .001) students. Preferred teaching and assessment methods were trainer-based communication trainings (73.1%), lectures (67.3%) and self-assessments in the student clinic (59.6%). CONCLUSION Communication curricula in dental education using methods such as lectures and trainer-based communication trainings may additionally need to include self-assessments to be effective from the students' perspective.

Abstract
AIM To investigate the healing after heterotopic mucosa transpositioning at dental implants and teeth. MATERIALS AND METHODS One hemimandible per dog (n = 4) was allocated to receive 3 implants (test), whereby 3 premolars on the contralateral side served as controls. After osseointegration, a Z-plasty was performed on the buccal aspect of the test and control sites to heterotopically move the zone of keratinized tissue (KT) into a region with non-keratinized tissue (nKT) and vice versa. Clinical measurements were performed before (T0) and at 12 weeks following heterotopic transposition (T1). Thereafter, specimens were processed for histological analysis. RESULTS Clinical measurements revealed that at T1, a band of KT was reestablished at teeth (mean: 2.944 ± 1.866 mm), whereas at implants, the transpositioned nKT resulted in a mucosa without any signs of keratinization (mean: 0 mm; p < .0001). At implant sites, the probing attachment level loss was more pronounced compared to tooth sites (-1.667 ± 1.195 mm and -1.028 ± 0.878 mm, respectively; p = .0076). Histologically, the transpositioned nKT, was accompanied by the formation of KT at the tooth but not at implant sites. The supracrestal soft tissues were statistically significantly higher at tooth compared to implant sites (2.978 ± 0.483 mm and 2.497 ± 0.455 mm, p = .0083). The transpositioned KT remained mostly unaltered in its morphological characteristics. CONCLUSIONS The findings of this study indicate that: (a) transpositioned KT may retain its morphological characteristics; and (b) transpositioned nKM was accompanied by the formation of KT at the tooth but not at implant sites.

Abstract
Dental anxiety is a prevalent concern in Western societies, affecting a broad demographic from children to the elderly, and posing a challenge to the delivery of oral health care. The Swiss Dental Association (SSO) has been conducting national surveys since 1980, with additional questions since 2010, to better understand the Swiss population's perception of the dental profession. Their 2010 and 2017 surveys aimed to gain more insight into dental anxiety across Switzerland, and to relate their findings to various demographic and socio-economic factors. A total of 2240 participants (1129 in 2010 and 1111 in 2017), demographically representative of Switzerland's socioeconomic distribution, were surveyed, with an even gender distribution (49.7% male and 50.3% female, p=0.7656). The mean age of the cohort was 43.5 ±16.0 years. The prevalence of dental anxiety decreased from 2010 to 2017. In 2010, 21.3% (CI: 19.0-23.7) reported higher levels of dental anxiety, which decreased to 13.3% (CI: 11.4-15.4) in 2017. Women consistently reported higher levels of dental anxiety than men in both years (2010: p<0.0001, 2017: p=0.0003). Logistic regression analysis revealed that higher levels of education (p<0.0001), trust in the dentist (p=0.0005) and satisfaction with the dentist (p=0.0489) significantly predicted lower levels of dental anxiety. In conclusion, these results highlight an overall decrease in dental anxiety from 2010 to 2017, but particularly among highly educated individuals and participants expressing satisfaction and trust in their dentist. While women consistently reported higher levels of anxiety, the overall results suggest promising trends in perceptions of oral health in Switzerland.

Abstract
AIM To investigate the spontaneous regeneration of the implanto-mucosal and dento-gingival unit after complete removal of keratinized tissue (KT). MATERIALS AND METHODS One hemi-mandible per dog (n = 4) was allocated to receive three dental implants (test sites, premolar region), whereas three premolars on the contralateral side were controls. After osseointegration, the entire KT (buccal + lingual) was surgically excised on all test and control sites, leaving the bone exposed. Clinical measurements were performed before excision (T0 ) and after 12 weeks (T1 ). Following healing, the animals were euthanized, and the specimens were histologically processed. Descriptive statistical analyses were performed. RESULTS Clinical measurements revealed that at T1 , on all teeth, a band of KT was spontaneously regenerated (mean width: 2.60 ± 0.66 mm), whereas on implants, KT was detected only occasionally at mesial or distal but not at buccal sites (mean total: 0.35 ± 0.53 mm; p < .0001). Histologically, spontaneous regeneration of the dento-gingival unit was evident, displaying masticatory mucosa. At the implant sites, on the other hand, the implanto-mucosal unit was characterized by a non-keratinized epithelium and elastic fibres, indicating the characteristics encountered in alveolar mucosa. CONCLUSION After excision of KT at implant sites, the spontaneous regeneration of the soft tissue is characterized by a non-keratinized epithelium typical for alveolar mucosa, while at tooth sites the spontaneous regeneration was characterized by soft tissue resembling gingiva.

Abstract
Tutor-supported comprehensive care training at the University of Bern School of Dental Medicine (SDM) has been used for many years. Therefore, the aim of this study was to evaluate dental students' opinions on tutor-supported training to identify key aspects of future course organisation that are important for students to achieve the minimum requirements for their graduation. A digital survey was developed and distributed among all fourth- and fifth-year dental students enrolled in the SDM in 2014 and 2016. A total of 28 (41.2%) and 21 (36.2%) students participated in the survey in 2014 and 2016, respectively. The average age of all respondents was 25.8 (±4.0) years. The proportion of females was 75% with no differences between groups, neither among classes nor years of the survey. The students felt well prepared following the bachelor's degree pre-clinical programme and a two-week introduction immediately preceding the clinical course. During clinical training, the students' experiences with their assigned tutors were positive even though waiting times for tutors during patient care as well as organisational efforts to manage attestations and logbooks were mentioned. For each discipline, patient assignment (ρ=0.54, p<0.0001) and frequently meeting with their tutors (ρ=0.56, p<0.0001) revealed the highest correlation with 1) achieving minimum requirements and 2) improving treatment planning skills in both fourth- and fifth-year dental students. In conclusion, tutor-supported comprehensive care training is well accepted by dental students while focusing on both patient assignment and frequent discussions with tutors may help students to better achieve minimum requirements in clinical dental education.

Abstract
This second and final part of the publication on the topic of sustainability in dental practices deals with the so-called workplace management, which describes the work processes and the consumption of energy and materials in the practice itself. Waste management is also addressed, which discusses the path of resources from the practice to disposal and recycling. Finally, an example from materials research is presented using implants.

Abstract
More than 740 million people worldwide are affected by periodontal disease and are at higher risk of secondary damage such as cardiovascular disease and type 2 diabetes, which place a considerable financial burden on healthcare systems. The aim of this study was to use a computer simulation to estimate the direct and indirect costs of prevention and treatment of gingivitis, periodontitis and related secondary damage in the Swiss population, paid both out of pocket (OOP) and from social welfare (SW). For three different scenarios, iterations with 200,000 simulated individuals over their assumed life span of 35 to 100 years corresponded to a period of four months in which an individual could move from one periodontal condition to the next, each associated with presumed direct and indirect treatment costs. Appropriate diagnosis and adherence to professional periodontal care had a strong benefit saving up to CHF 5.94 billion OOP and CHF 1.03 billion SW costs for the current Swiss population. Considering direct and indirect health care costs, the total expected costs for a 35-year-old individual until death were CHF 17'310 with minimal care and CHF 15'606 with optimal care, resulting in savings of CHF 1'704. In conclusion, early detection and appropriate treatment of periodontitis can help to reduce both overall costs of treating periodontitis and associated secondary damage, especially in the second half of life. These cost savings may further pay off on an individual level through regular supportive periodontal care, both for treatments paid out-of-pocket and those covered by social welfare.

Abstract
Sustainability in dental practices is playing an increasingly important role. External and internal factors have an influence on the emissions of a practice. The external factors include the domains of politics, science, and education. It is eminent that the discussion on the environmental impact in healthcare finds its way into these three domains, as it lays the foundation for behavioural change and thus paves the way for a greener future. The internal factors include practice operations, supply chain, employees, and patients. Overall, the topic of sustainability is hardly prevalent in the dental workplace. This first article of a two-part series highlights how sustainability in dentists' practices and work is influenced by many environmental factors which, taken together, can affect the interplay between the environment and dentistry.

Abstract
The impact of lifestyle factors has been increasingly studied and discussed in oral healthcare. Positive lifestyle factors are important in maintaining oral health or controlling disease, but they are not easy to adopt over the long term. Along with public health initiatives within communities and groups, there is a role for behavior change interventions delivered in dental practice settings to improve the periodontal health of individuals. Behavior management is now seen as a part of both prevention and therapy of periodontal diseases. This article summarizes the evidence on behavioral strategies for periodontal health to inform and assist oral healthcare professionals in implementing behavior change in their practice. In addition, strategies for education and training in communication and behavior change techniques are considered.

Abstract
Asylum-seeking adolescents who have passed the age of mandatory schooling may not have had the opportunity to receive oral hygiene instructions (OHI) similar to Swiss adolescents. Therefore, the aim of this study was to evaluate the impact of a single information session with OHI on both the knowledge about the consequences of lacking oral hygiene and the likelihood of implementing these instructions in unaccompanied adolescent asylum seekers living in Switzerland. Before and after a single information session with OHI, adolescent asylum seekers in two asylum centres (Menziken and Suhr, AG) were surveyed with written questionnaires. During the event, the consequences of lacking oral hygiene on oral health were explained and the Bass brushing technique was instructed and practised. The present analysis included 30 male asylum seekers aged 15-18. In total, 90% (n=27) cleaned their teeth daily and 70% (n=13) had received previous OHI at their school (19.1%) or a doctor's office (9.5%) in their country of origin or in Switzerland (19.1%), respectively. Following the event, 90% (n=27) stated they had learned something new and 93.3% (n=28) wanted to implement the instructions in their daily routine. While 63.3% (n=19) of the respondents knew the consequences of lacking oral hygiene on oral health before the event, this value increased to 96.7% (n=29) reaching statistical significance (p=0.0039). In conclusion, the results of the present study suggest that the implementation of a single information session with OHI in asylum centres may improve the level of knowledge in adolescent asylum seekers and their oral health.

Abstract
We evaluated, in this study, the clinical, microbiological and immunological effects of local drug delivery (LDD) or photodynamic therapy (PDT), adjunctive to subgingival instrumentation (SI) in persistent or recurrent periodontal pockets in patients enrolled in supportive periodontal therapy (SPT) after one year. A total of 105 patients enrolled in SPT with persistent/recurrent pockets were randomly treated with SI +PDT or SI + LDD or SI (control). The number of treated sites with bleeding on probing (n BOP+), probing pocket depths (PPD), clinical attachment level (CAL), full-mouth plaque and bleeding scores (gingival bleeding index, %bleeding on probing-BOP) was evaluated at baseline and after 12 months. Additionally, eight periodontopathogens and the immunomarkers IL-1β (interleukin)and MMP-8 (matrix metalloprotease) were quantitatively determined using real-time PCR and ELISA, respectively. All three treatments resulted in statistically significant clinical improvements (p < 0.05) without statistically significant intergroup differences (p > 0.05), which were maintained up to 12 months. The presence of BOP negatively affected the PPD and CAL. Moreover, statistically significantly fewer bleeding sites at 12 months were observed in the test groups (p = 0.049). Several periodontopathogens were reduced after 12 months. In conclusion, the present data indicate that in periodontal patients enrolled in SPT, treatment of persistent/recurrent pockets with SI alone or combined with either PDT or LDD may lead to comparable clinical, microbiological and immunological improvements, which are maintained up to 12 months. Secondly, the presence of BOP directly impacts the PPD and CAL.

Abstract
BACKGROUND To evaluate periodontal disease progression (PDP) and potentially detectable effects of a single episode of scaling and root planing (se-SRP) in subjects lacking professional dental care and oral hygiene practices for >40 years. METHODS In 2013, se-SRP was offered to all available subjects from the original cohort of 480 males initially established in 1970. From a total of 75 attending the previous examination in 2010 (baseline), 27 consented to receive the intervention while 18 declined and served as controls. Clinical data were recorded again in 2014 (follow-up) similarly to the previous surveys (1970 to 2010). RESULTS Subjects' mean age in 2010 was 62.5 (± 3.6, test) and 61.9 (± 3.8, control) years. At follow-up, both groups presented with elevated tooth loss of 1.2 (from 15.5 ± 9.0, test) and 1.5 (from 17.9 ± 6.6, control) resulting in 1,392 (test) and 1,061 (control) sites available for further analysis. In both groups, clinical attachment level (CAL) loss and probing depths (PD) deteriorated. PD increase of 0.22 mm (± 1.70) in the test group was significantly higher compared with the control group (0.08 mm ± 1.30) (P <0.0001) demonstrating unaffected PDP. Computed estimates of further PDP revealed CAL and PD reductions in subjects aged ≥40 years. Specifically, the latter was positively correlated with tooth loss in subjects aged ≥40 years (P = 0.69, P = 0.0012) and ≥50 years (r = 0.62, P <0.0001). CONCLUSION se-SRP in previously untreated periodontitis subjects aged ≥50 years may be ineffective in reducing PDP thus demanding advanced preventive measures, treatment in the first half of life, and sustained access to supportive care.

Abstract
Aim To evaluate the Implant Disease Risk Assessment (IDRA) tool for the prediction of peri‐implantitis in treated periodontitis patients with implant‐supported fixed dental prostheses (FDPs) after at least 5 years of function. Material and methods From the patient pool of implant patients enrolled in a regular supportive periodontal therapy programme (SPT) for at least 5 years, 239 patients were screened. Eighty patients met the inclusion criteria and underwent evaluation through the criteria of the IDRA tool. Areas under the curve (AUCs) for receiver operating characteristic (ROC) curves including 95% confidence intervals were estimated. Results Seventy‐nine patients (43 males and 36 females, 8 smokers), aged on average 59.0 years (range: 40–79 years) at baseline (i.e. FDP delivery) were analysed. The calculated IDRA‐risk was in 34 patients (42.5%) a moderate risk, while 45 patients (56.3%) were considered at high IDRA‐risk. One patient categorized at low IDRA‐risk was excluded from the analysis. The AUC was 0.613 (95% CI: 0.464–0.762) if the IDRA‐risk was associated with prevalence of peri‐implantitis at the most recent follow‐up. Peri‐implantitis was diagnosed in 4 patients (12%) at moderate and in 12 patients (27%) at high IDRA‐risk, respectively. The calculated odds ratio for developing peri‐implantitis in patients with high IDRA‐risk compared with patients with moderate IDRA‐risk was 2.727 with no statistically significant difference between the two groups (95% CI: 0.793–9.376). Conclusion Within the limitations of the present retrospective study, the IDRA algorithm might represent a promising tool to assess patients at moderate or high risk of developing peri‐implantitis.

Abstract
AIM This systematic review investigates the impact of specific interventions aiming at promoting behavioural changes to improve oral hygiene (OH) in patients with periodontal diseases. METHODS A literature search was performed on different databases up to March 2019. Randomized and non-randomized controlled trials evaluating the effects of behavioural interventions on plaque and bleeding scores in patients with gingivitis or periodontitis were considered. Pooled data analysis was conducted by estimating standardized mean difference between groups. RESULTS Of 288 articles screened, 14 were included as follows: 4 studies evaluated the effect of motivational interviewing (MI) associated with OH instructions, 7 the impact of oral health educational programmes based on cognitive behavioural therapies, and 3 the use of self-inspections/videotapes. Studies were heterogeneous and reported contrasting results. Meta-analyses for psychological interventions showed no significant group difference for both plaque and bleeding scores. No effect was observed in studies applying self-inspection/videotapes. CONCLUSIONS Within the limitations of the current evidence, OH may be reinforced in patients with periodontal diseases by psychological interventions based on cognitive constructs and MI principles provided by oral health professionals. However, no conclusion can be drawn on their specific clinical efficacy as measured by reduction of plaque and bleeding scores over time.

Abstract
AIM To compare the adjunctive effects of lasers or antimicrobial photodynamic therapy (aPDT) to non-surgical mechanical instrumentation alone in untreated periodontitis patients. MATERIALS AND METHODS Two focused questions were addressed using the Population, Intervention, Comparison and Outcome criteria as follows: in patients with untreated periodontitis, (a) does laser application provide adjunctive effects on probing pocket depth (PPD) changes compared with non-surgical instrumentation alone? and (b) does application of aPDT provide adjunctive effects on PPD changes compared with non-surgical instrumentation alone? Both randomized controlled clinical trials (RCTs) and controlled clinical trials (CCTs) were included. Results of the meta-analysis are expressed as weighted mean differences (WMD) and reported according to the PRISMA guidelines. RESULTS Out of 1,202 records, 10 articles for adjunctive laser and 8 for adjunctive aPDT were included. With respect to PPD changes, 1 meta-analysis including 2 articles (total n = 42; split-mouth design) failed to identify a statistically significant difference (WMD = 0.35 mm; 95%CI: -0.04/0.73; p = .08) in favour of adjunctive aPDT (wavelength range 650-700 nm). In terms of adjunctive laser application, a high variability of clinical outcomes at 6 months was noted. Two articles included patient-reported outcomes and 10 reported on the presence/absence of harms/adverse effects. CONCLUSIONS Available evidence on adjunctive therapy with lasers and aPDT is limited by (a) the low number of controlled studies and (b) the heterogeneity of study designs. Patient-reported benefits remain to be demonstrated.

Abstract
PURPOSE To assess the effect of age on the mean percentage of bleeding on probing (BOP) during supportive periodontal therapy (SPT) in patients enrolled in SPT for at least 5 years.
Materials and Methods: This study was performed as a retrospective analysis of data collected from SPT patients initially diagnosed with gingivitis or mild to severe periodontitis. Two groups of patients were selected: in group A, younger adults (age ≤ 35 years) were included while group B consisted of older SPT patients (age ≥ 65 years). BOP in the two groups was compared according to both disease severity and % compliance with SPT visits.
Results: BOP in all patients (n = 236) was 19.2% (± 12.4). Group A (n = 110) presented mean BOP levels of 19.7% (± 11.8), while lower BOP levels of 18.7% (± 13.0) were found in group B (n = 126; p = 0.5272). Older patients demonstrating high % compliance had lower mean BOP levels (14.2% ± 9.5) than younger patients (18.0% ± 11.7; p = 0.0841). Similarly, BOP was lower in older patients with moderate (group B: 18.4% ± 12.1, group A: 19.3% ± 14.6, p = 0.0541) or severe periodontitis (group B: 22.4% ± 11.4, group A: 23.2% ± 14.0; p = 0.3440). In patients with moderate or severe periodontitis and higher % compliance with SPT, the mean BOP was statistically significantly lower in older patients than in younger patients (moderate: 14.4% ± 11.9 vs 19.4% ± 15.1, p < 0.0001; severe: 13.2% ± 11.1 vs 18.3% ± 17.5, p = 0.0170).
Conclusion: Older patients enrolled in SPT may present lower levels of BOP. This finding should be considered when determining SPT intervals with elderly patients.

Abstract
BACKGROUND Implant-supported restorations with cantilever extension may display high rates of biological and technical complications. PURPOSE To report the outcomes of single-unit crowns with cantilever extension (SCCs). MATERIALS AND METHODS Patients with SCCs were reevaluated after ≥10 years of loading. Radiographic marginal bone levels (mBLs) at baseline (ie, delivery of SCCs) and follow-up were calculated and compared between implant surfaces adjacent to and distant from the cantilever extension. Implant survival and success rates were calculated. RESULTS Twenty-one patients with 25 SCs supported by 25 implants were reevaluated after a mean of 13.6 ± 3.8 years (range: 10-19 years). No implants were lost. The mean overall mBLs changed from 0.99 mm ± 0.95 at baseline to 0.95 mm ± 0.99 at follow-up (p = 0.853). The mean pocket probing depths changed from 3.39 mm ± 0.62 at baseline to 3.34 mm ± 0.54 at follow-up (p = 0.635). Loss of retention occurred 3× in 2 patients (14.3%). At follow-up, peri-implant health was diagnosed in 10 (48%) and peri-implant mucositis in 11 (52%) patients, respectively. CONCLUSIONS Within the limitations of the present study, the use of implant-supported SCs with cantilever extension in posterior areas represents a reliable long-term treatment option with a 100% implant survival rate and minimal marginal bone level changes.

Abstract
PURPOSE To compare clinical outcomes and oral fluid biomarkers in gingivitis subjects using an electric toothbrush/irrigator combination (test) or a manual toothbrush alone (control) over 8 weeks. MATERIALS AND METHODS Subjects were randomly assigned to two groups of n = 30. In both groups, toothbrushing was performed twice daily at home and no additional interdental cleaning aids were allowed. Plaque Index (PLI), Gingival Index (GI), whole saliva (WS), and gingival crevicular fluid (GCF) samples were collected at weeks 2, 4, and 8. RESULTS Subjects' mean age was 23 years and 52% were female. Overall baseline means were 1.31 for PLI, 1.07 for GI, and 34.9 for number of bleeding sites. At every follow-up visit, both groups differed statistically significantly (p < 0.001) from baseline for all clinical parameters. The test group demonstrated statistically significantly (p < 0.001) greater reductions in GI vs the control group by 18% at week 2, 17% at week 4 and 24% at week 8. The test group also demonstrated statistically significantly (p < 0.002) greater reductions in the number of bleeding sites vs the control group by 33% at week 2, 34% at week 4 and 43% at week 8. Between-group comparisons for both WS and GCF revealed numerical trends for decreased levels of interleukin (IL)-1β in GCF after 4 and 8 weeks, but these were not statistically significant. CONCLUSION In subjects using the electric toothbrush/irrigator combination, increased clinical improvements may be found accompanied by similarly improved trends for oral fluid biomarkers such as IL-1β.

Abstract
Dental calculus has a secondary effect on the pathogenesis of periodontal diseases by harboring bacterial biofilm on its rough surfaces. Consequently, professional removal of both calculus and biofilm is a crucial part of the therapy and prevention of gingivitis and periodontitis. Today, crystal growth inhibitors such as zinc ions in the form of zinc chloride or zinc citrate, and pyrophosphates alone or in combination with copolymer are added to toothpastes to prevent the mineralization of the dental biofilm. In addition, triclosan is used as an antimicrobial agent in combination with copolymer as an additive in toothpastes to reduce the amount of plaque and thus the substrate for calculus formation. In clinical trials, chemical additives have demonstrated an inhibiting impact on calculus formation. However, it must be clarified that in addition to home-based oral hygiene, the formation of dental calculus depends on other factors such as access to professional dental care, diet, age, ethnicity, time since last professional tooth cleaning, systemic diseases or medications. However, since chemical additives in toothpastes do not reach the deeper sites of periodontal pockets, they are recommended for the inhibition of supragingival calculus formation, thus assisting the primary prevention of gingivitis as well as the secondary prevention of periodontal disease.

Abstract
The main aim of the present study was to gain a better understanding of the management of dental anxiety reported by dental practitioners in western Switzerland. In 2013, an 18-item electronic questionnaire was sent to dental practitioners in the Swiss Romandy. A total of 140 (18.6%) questionnaires were included in the analysis. About four out of five practitioners (79.4%) involved with dental emergency service had at least one occurrence with dental phobic patients. The majority of the respondents stated that both dental anxiety and dental phobia increases stress in the dental practice with frequencies of 90.0% and 88.5%, respectively. Among the 119 respondents using anxiety reduction methods (85.0%), an overall of 51 (42.9%) reported using pharmacological methods while 89.9% (n = 107) used psychological methods. Female dentists were using psychological anxiety reduction methods three times more frequently than male dentists reaching borderline statistical significance (OR = 3.0, p = 0.0591). Out of 140 respondents, only 28 (20.1%) received education and training in dental anxiety reduction methods. The majority of these (66.4%; n = 83) stated that their education was inadequate and 55.8% (n = 77) requested further education and training. It can be concluded that more education and training of dental anxiety reduction methods are needed.

Abstract
For two decades, in periodontology, the effects of periodontal disease on pregnancy, low birth weight or premature birth have been investigated. Even hypertensive diseases during pregnancy have an influence on pregnancy possibly leading to the death of the untreated mother. Due to the stable increase in birth rates,in addition to women’s employment and careers, this topic has become more relevant in dentistry than ever before. Rates of prematurity and reduced birth weight are both increasing worldwide and are the main cause of neonatal morbidity and mortality. The need for action regarding the prevention, education and health care of pregnant women is given worldwide. This article first gives an overview of the topic and further discusses the necessary interdisciplinary gynecological and dental therapy. In the daily practice, dentists will be able to make a small but not insignificant contribution to improving the situation of affected women and their children.

Abstract
AIM To relate the time between recall visits and residual periodontal probing depths (PPDs) to periodontal stability in patients enrolled in supportive periodontal therapy (SPT). MATERIALS AND METHODS Retrospective data on residual PPDs from 11,842 SPT visits were evaluated in SPT patients at the Medi School of Dental Hygiene (MSDH), Bern, Switzerland, 1985-2011. A residual PPD-based algorithm was developed to compute SPT intervals with no expected change of residual PPD. RESULTS A total of 883 patients aged 43.9 (±13.0) years and 55.4% (n = 489) being females were identified. Linear mixed model analysis yielded highest statistically significant impact on PPD change with time between SPT visits, presence of residual PPD ≥4 mm, and bleeding on probing (p < 0.0001). Patients returning for SPT five times consecutively earlier than computed presented mean % PPDs ≥4 mm of 5.8% (±3.9) compared with patients returning later (19.2%, ±7.6) (p < 0.0001). Additionally, patients attending >50% of their SPT visits earlier versus later demonstrated increased periodontal stability after 5 years (p = 0.0002) and a reduced frequency of tooth loss (0.60, ±0.93 versus 1.45, ±2.07) after 20 years (p < 0.0001). CONCLUSIONS To reach and maintain periodontal stability during SPT, individual quantitative data from comprehensive residual PPD profiles may contribute to the improved planning of SPT intervals.

Abstract
OBJECTIVES To assess long-term attachment and periodontitis-related tooth loss (PTL) in untreated periodontal disease over 40 years. MATERIAL AND METHODS Data originated from the natural history of periodontitis study in Sri Lankan tea labourers first examined in 1970. In 2010, 75 subjects (15.6%) of the original cohort were re-examined. RESULTS PTL over 40 years varied between 0 and 28 teeth (mean 13.1). Four subjects presented with no PTL, while 12 were edentulous. Logistic regression revealed attachment loss as a statistically significant covariate for PTL (p < .004). Markov chain analysis showed that smoking and calculus were associated with disease initiation and that calculus, plaque, and gingivitis were associated with loss of attachment and progression to advanced disease. Mean attachment loss <1.81 mm at the age of 30 yielded highest sensitivity and specificity (0.71) to allocate subjects into a cohort with a dentition of at least 20 teeth at 60 years of age. CONCLUSIONS These results highlight the importance of treating early periodontitis along with smoking cessation, in those under 30 years of age. They further show that calculus removal, plaque control, and the control of gingivitis are essential in preventing disease progression, further loss of attachment and ultimately tooth loss.

Abstract
AIMS The aim of this study was to evaluate dental students' self-perceived communication skills for patient motivation over the course of their training. MATERIALS AND METHODS Pre-clinical and clinical dental students at the University of Bern School of Dental Medicine were surveyed annually from 2008 to 2011 utilising a written questionnaire. Self-reported data were pooled from all classes per time-point in the curriculum. RESULTS A total of 157 students were surveyed from five classes with an overall response rate of 94.8%. A total of 393 questionnaires were available for analysis. The self-perceived skill-sets for general patient care and patient communication were rated at the end of the first clinical year with mean Visual Analog Scale values of 75.0 ± 1.6 and 75.1 ± 1.5, respectively. During the second clinical year, the self-perceived skills increased in both patient care (82.5 ± 1.2, P = 0.0004) and patient communication (81.4 ± 1.4, P = 0.0034). The students rated their competence higher when providing oral hygiene instructions as opposed to motivating patients to quit tobacco use, modify their diet or employ stress-reduction strategies (P < 0.005). At the end of the pre-clinical year, 74.5% of the students expressed interest in receiving more extensive communication training (P < 0.004). CONCLUSIONS Though dental students in this study demonstrated a steady increase in their level of comfort motivating patients to utilise oral hygiene instructions, they also expressed the desire for more motivational training early in their curriculum. Therefore, these results may indicate the need to enhance communications training in patient motivation on all behavioural aspects early in the dental curriculum.

Abstract
Aim: Periodontal therapy is highly dependent on a patient's long-term adherence with regard to oral hygiene, diet, and regular check-ups at the dentist. Motivational Interviewing (MI) is a client-centered, directive method for encouraging a patients' behavioral health change. The aim of this systematic review was to reveal the effects of MI as an adjunct to periodontal therapy. Methods: Three databases (PubMed, Cochrane Library, and Web of Science) were reviewed for randomized controlled clinical trials. Articles were included when using MI as an adjunct to periodontal therapy and presenting clinical periodontal and oral hygiene related parameters. Two authors independently coded the relevant articles. Results: The search yielded 496 articles. After analysis and exclusion, a total of five papers could be included. The quality of the articles ranged between 72–88%. The two independent raters showed a high inter-rater reliability (Cohens-Kappa = 0.89). In two studies MI showed a significant positive effect on bleeding on probing and plaque values. One study showed improvement of self-efficacy in interdental cleaning. Two studies showed no influence of MI on periodontal parameters of the patients. Conclusion: The use of MI as an adjunct to periodontal therapy might have a positive influence on clinical periodontal parameters (plaque values, gingival, and periodontal inflammation) and psychological factors related to oral hygiene (self-efficacy). Due to the low body of evidence further studies are needed. Future studies should include fidelity measures of the applied MI, a high number of counselors, several MI sessions, and long-term study follow-up to show potential effects.

Abstract
PURPOSE To evaluate the awareness of cigarette smoking as a risk factor for chronic periodontitis in patients either undergoing active periodontal treatment (APT) or enrolled in supportive periodontal therapy (SPT). MATERIALS AND METHODS Comprehensive tobacco use history was collected with a questionnaire in 50 patients before and after APT (test) and in 50 patients (control) enrolled in SPT at the School of Dental Medicine, University of Bern. Carbon monoxide (CO) exhalation levels were measured in both APT and SPT patients. RESULTS In the test group, 94% (n = 47) completed the study. Before APT, 48% of these (n = 24) knew about the association between smoking and periodontal disease, while 42% (n = 21) assumed a possible association and 10% (n = 5) did not. Following APT, 53% (n = 25) knew about the association, while 34% (n = 17) still assumed a possible association and 10% (n = 5) did not. In the control group, 60% (n = 30) of SPT patients knew about the association of smoking with periodontal disease, while 30% (n = 15) assumed an association and 10% (n = 5) were not aware of any association. In both APT and SPT patients, neither between-group nor baseline to follow-up differences were detected (p > 0.05). CONCLUSIONS Brief interventions for tobacco cessation during APT or SPT failed to increase periodontal patients' awareness of smoking as a risk factor for chronic periodontitis. In order to both increase awareness and motivation to quit tobacco use, more counseling than conventional brief interventions may be needed. Key words: chronic periodontitis, exhaled carbon monoxide, patient education, risk factor, smoking, smoking cessation.

Abstract
INTRODUCTION The aim of the present study was to evaluate both survival and failure rates of endodontically treated teeth restored with or without fiber post-retained restorations after a mean observation period of at least 5 years. METHODS A total of 144 single-rooted and multirooted teeth in 100 subjects were endodontically treated following a predetermined aseptic protocol and restored with either a fiber post and a composite core or a composite filling without intraradicular retention. A fiber post was cemented when the teeth presented with only 1 wall and/or less than one third of the remaining height of the clinical crown. After a comprehensive treatment plan, the teeth were restored with either a direct composite restoration or a single-unit crown. Endodontically treated teeth supporting fixed and removable dental prostheses and telescopic crowns were excluded from the analysis. Success was defined as tooth survival without any treatment of biological and/or technical complications. RESULTS The overall tooth survival rate was 89.6% after a mean observation time of 8.8 ± 2.3 years. The survival rate of teeth with a fiber post amounted to 94.3%, and for teeth without a post, it was 76.3% (P < .001). The main reason for tooth loss was root fracture (9.7%). No loss of post retention was observed. Successfully treated teeth without any biological and/or technical complications and requiring no additional treatment during the entire observation period amounted to 79.9%. CONCLUSIONS Endodontically treated teeth restored with fiber posts and either a direct composite restoration or a single-unit crown yielded higher survival and success rates compared with teeth restored without fiber posts. Vertical fractures of roots not containing a post represented a frequently encountered and serious problem.

Abstract
OBJECTIVES To characterize the physical characteristics of a new low abrasive erythritol powder (EPAP) and to evaluate its influence on the clinical and microbiologic parameters over a period of 6 months in patients undergoing supportive periodontal therapy (SPT). METHOD AND MATERIALS Prior to the clinical application, the particle size and abrasion level of EPAP were compared to glycine air-polishing powder (GPAP) ex vivo. Subsequently, 40 chronic periodontitis patients previously enrolled in SPT were randomly assigned into two groups for the treatment with subgingival EPAP or repeated scaling and root planing (SRP). At baseline (BL), bleeding on probing positive (BOP+) sites with probing pocket depth (PPD) of ≥ 4 mm but no detectable calculus were defined as study sites. During SPT, these sites were either treated by EPAP or SRP at BL, 3, and 6 months (3M, 6M). When indicated, additional SRP was provided. Plaque Index, BOP, PPD, clinical attachment level (CAL), and subgingival plaque were evaluated at BL and 6M. RESULTS EPAP yielded lower abrasiveness and smaller particle sizes when compared to GPAP. In 38 patients completing the study, EPAP and SRP resulted in significant reductions of BOP% (EPAP, 40.45%; SRP, 42.53%), PPD (EPAP, -0.67; SRP, -0.68), and increase of CAL (EPAP, 0.48; SRP, 0.61) while at 6M no statistically significant between-group differences were observed (P > .05). Microbiologic evaluation revealed minor shifts in the composition of the subgingival biofilm without influence on periodontopathogenic bacteria. CONCLUSION The subgingival use of EPAP by means of an air-polishing device may be considered safe and may lead to comparable clinical and microbiologic outcomes to those obtained with SRP. CLINICAL RELEVANCE The subgingival use of EPAP appears to represent a promising modality for the removal of subgingival biofilm during SPT.

Abstract
AIM To systematically assess the efficacy of oral health behaviour change counselling for tobacco use cessation (TUC) and the promotion of healthy lifestyles. MATERIALS AND METHODS Systematic Reviews, Randomized (RCTs), and Controlled Clinical Trials (CCTs) were identified through an electronic search of four databases complemented by manual search. Identification, screening, eligibility and inclusion of studies were performed independently by two reviewers. Quality assessment of the included publications was performed according to the AMSTAR tool for the assessment of the methodological quality of systematic reviews. RESULTS A total of seven systematic reviews were included. With the exception of inadequate oral hygiene, the following unhealthy lifestyles related with periodontal diseases were investigated: tobacco use, unhealthy diets, harmful use of alcohol, physical inactivity, and stress. Brief interventions for TUC were shown to be effective when applied in the dental practice setting while evidence for dietary counselling and the promotion of other healthy lifestyles was limited or non-existent. CONCLUSIONS While aiming to improve periodontal treatment outcomes and the maintenance of periodontal health current evidence suggests that tobacco use brief interventions conducted in the dental practice setting were effective thus underlining the rational for behavioural support.

Abstract
OBJECTIVES The aim of this study was to compare early wound healing, tooth staining and patient acceptance with two different post-surgical maintenance protocols. MATERIALS AND METHODS Forty patients scheduled for flap surgery to treat periodontal pockets or accommodate dental implants were randomly assigned to receive the following two different post-surgical maintenance protocols: (a) 2 weeks rinsing with a 0.05 % chlorhexidine digluconate (CHX)/herbal extract combination (test) or (b) a 0.1 % CHX solution (control). Early wound healing was evaluated clinically and immunologically. Tooth staining and patient acceptance were assessed by means of visual analogue scale (VAS). RESULTS Both groups presented with comparable wound healing profiles. No statistically significant differences were observed between the two protocols regarding early wound healing and plaque index (p > 0.05). However, in the control group, statistically significantly more patients felt discomfort due to tooth staining (p = 0.0467). Compared with patients from the test group, patients in the control group reported statistically significant more irritation of taste at week 1 (p = 0.0359) and at week 2 (p = 0.0042). CONCLUSIONS The present findings indicate that the two CHX protocols resulted in comparable healing and inhibition of plaque formation. Tooth staining and subjective discomfort related to irritation of taste were more frequent in the control group. CLINICAL RELEVANCE A post-operative protocol including 0.05 % CHX/herbal extract may have the potential to improve patient compliance during post-operative maintenance.

Abstract
Swedish snus (smokeless moist tobacco) is becoming increasingly popular in Switzerland. Consumption and import of snus are permitted in Switzerland, however, sales were prohibited in 2004 by the European Court. Snus is an addictive nicotine containing product, which additionally contains carcinogenic nitrosamines. Both consumers and oral health professionals are lacking important information on the health consequences. The present paper therefore reviews the impact of snus consumption on oral health. For all snus consumers and particularly for adolescents, more detailed information should be provided by oral health professionals. Specifically with heavy snus users, more frequent follow-up is recommended to detect potential precancerous lesions or neoplasias in early stages.

Abstract
PURPOSE This retrospective study assessed the 10-year outcomes of titanium implants with a sandblasted and acid-etched (SLA) surface in a large cohort of partially edentulous patients. MATERIALS AND METHODS Records of patients treated with SLA implants between May 1997 and January 2001 were screened. Eligible patients were contacted and invited to undergo a clinical and radiologic examination. Each implant was classified according to strict success criteria. RESULTS Three hundred three patients with 511 SLA implants were available for the examination. The mean age of the patients at implant surgery was 48 years. Over the 10-year period, no implant fracture was noted, whereas six implants (1.2%) were lost. Two implants (0.4%) showed signs of suppuration at the 10-year examination, whereas seven implants had a history of peri-implantitis (1.4%) during the 10-year period, but presented with healthy peri-implant soft tissues at examination. The remaining 496 implants fulfilled the success criteria. The mean Plaque Index was 0.65 (±0.64), the mean Sulcus Bleeding Index 1.32 (±0.57), the mean Probing Depth 3.27 mm (±1.06), and the mean distance from the implant shoulder to the mucosal margin value -0.42 mm (±1.27). The radiologic mean distance from the implant shoulder to the first bone-to-implant contact was 3.32 mm (±0.73). CONCLUSION The present retrospective analysis resulted in a 10-year implant survival rate of 98.8% and a success rate of 97.0%. In addition, the prevalence of peri-implantitis in this large cohort of orally healthy patients was low with 1.8% during the 10-year period.

Abstract
OBJECTIVES The aim of this prospective, randomized, controlled clinical study was to compare the clinical outcomes of the subgingival treatment with erythritol powder by means of an air-polishing (EPAP) device and of scaling and root planing (SRP) during supportive periodontal therapy (SPT). METHOD AND MATERIALS 40 patients enrolled in SPT were randomly assigned to two groups of equal size. Sites had to show signs of inflammation (bleeding on probing [BOP]-positive) and a probing pocket depth (PPD) of ≥ 4 mm, however, without presence of detectable subgingival calculus. During SPT, these sites were treated with EPAP or SRP, respectively. Full mouth and site-specific plaque indices, BOP, PPD, and clinical attachment level (CAL) were recorded at baseline (BL) and at 3 months, whereas the percentage of study sites positive for BOP (BOP+) was considered as primary outcome variable. Additionally, patient comfort using a visual analog scale (VAS) and the time needed to treat per site was evaluated. RESULTS At 3 months, mean BOP level measured 45.1% at test sites and 50.6% at control sites, respectively, without a statistically significant difference between the groups (P > .05). PPD and CAL slightly improved for both groups with comparable mean values at 3 months. Evaluation of patient tolerance showed statistically significantly better values among patients receiving the test treatment (mean VAS [0-10], 1.51) compared to SRP (mean VAS [0-10], 3.66; P = .0012). The treatment of test sites was set to 5 seconds per site. The treatment of control sites, on the other hand, lasted 85 seconds on average. CONCLUSION The new erythritol powder applied with an air-polishing device can be considered a promising modality for repeated instrumentation of residual pockets during SPT. CLINICAL RELEVANCE With regard to clinical outcomes during SPT, similar results can be expected irrespective of the two treatment approaches of hand instrumentation or subgingival application of erythritol powder with an air-polishing device in sites where only biofilm removal is required.

Abstract
PURPOSE To determine whether smokers report having less adequate oral hygiene habits than nonsmokers. MATERIALS AND METHODS Using a 24-item questionnaire addressing both smoking and oral hygiene habits, patients from three periodontal practices in Spain were evaluated. In order to assess the periodontal status of all patients, immediately following the survey, the patients were examined clinically and categorised according to the American Dental Association (ADA) classification for periodontal diseases. RESULTS 762 patients with ADA type I gingivitis (4.1%), type II early periodontitis (31.2%), type III moderate periodontitis (39.2%) and type IV advanced periodontitis (25.5%) were surveyed. A total of 289 smokers (38.0%) and 402 (52.8%) nonsmokers participated in the study: 77 (10.1%) participants were identified as heavy smokers (>20 cigarettes/day), along with 122 (16.0%) moderate smokers (10-20 cigarettes/day) and 90 (11.8%) light smokers (<20 cigarettes/day). A greater proportion of nonsmokers brushed their teeth two (37.8%) or more (22.9%) times a day compared with moderate smokers (twice: 32.0%, more: 15.6%) and heavy smokers (twice: 32.5%, more: 15.6%), respectively (p < 0.05). Heavy smokers used dental floss statistically significantly less frequently (10.4%) than nonsmokers (21.6%) (p < 0.05). No statistically significant differences were found between smokers and nonsmokers regarding the use of mouthwashes (p > 0.05). CONCLUSIONS This study revealed comparable oral hygiene habits in nonsmokers and light smokers. However, heavy smokers were found to have worse oral hygiene habits than nonsmokers.

Abstract
AIM To systematically assess the efficacy of patient-administered mechanical and/or chemical plaque control protocols in the management of peri-implant mucositis (PM). MATERIAL AND METHODS Randomized (RCTs) and Controlled Clinical Trials (CCTs) were identified through an electronic search of three databases complemented by manual search. Identification, screening, eligibility and inclusion of studies was performed independently by two reviewers. Studies without professional intervention or with only mechanical debridement professionally administered were included. Quality assessment was performed by means of the Cochrane Collaboration's tool for assessing risk of bias. RESULTS Eleven RCTs with a follow-up from 3 to 24 months were included. Definition of PM was lacking or heterogeneously reported. Complete resolution of PM was not achieved in any study. One study reported 38% of patients with complete resolution of PM. Surrogate end-point outcomes of PM therapy were often reported. The choice of control interventions showed great variability. The efficacy of powered toothbrushes, a triclosan-containing toothpaste and adjunctive antiseptics remains to be established. High quality of methods and reporting was found in four studies. CONCLUSIONS Professionally- and patient-administered mechanical plaque control alone should be considered the standard of care in the management of PM. Therapy of PM is a prerequisite for the prevention of peri-implantitis.

Abstract
OBJECTIVES To evaluate possible differences in periodontal inflammatory, microbiological and clinical parameters between women with preterm premature rupture of membranes (PPROM) and controls with uncomplicated pregnancies. MATERIALS AND METHODS Fifty-six women (32 test (PPROM) and 24 controls (uncomplicated pregnancies)) were examined at three time-points (T1: gestational weeks 20-35, T2: within 48 h after parturition, T3: 4-6 weeks after parturition). The examinations included assessment of the Periodontal Screening Index, collection of gingival crevicular fluid (GCF) and subgingival as well as vaginal bacterial sampling. RESULTS Periodontal inflammation was found to be higher in the test compared with the control group (p < 0.05) and decreased over time in both groups (p < 0.05). Microbiological outcomes showed no intergroup differences (p > 0.05) in prevalence of bacteria, but a decrease in subgingival periodontopathogens from T1 to T2 in the test group (p < 0.05) was observed. Interleukin (IL)-1β levels in GCF at T2 were not different between groups (p > 0.05). In women with PPROM, GCF levels of IL-8 (p < 0.05) and C-reactive protein (p < 0.05) were lower and IL-10 levels higher (p < 0.05) compared with controls. CONCLUSIONS Periodontal inflammation is elevated during pregnancy and seems to be more pronounced in women with PPROM. CLINICAL RELEVANCE The findings of the present study revealed an association between periodontal inflammation and PPROM, thus emphasizing the importance of optimizing self-performed oral hygiene in pregnant women.

Abstract
OBJECTIVES Dental phobia is a psychological disease and a possible contraindication for implant therapy. The study aimed to show that implant therapy in dental-phobic patients (DP, test group) after adequate psychological and dental pretreatment (PDPT) is successfully possible and results in a similar implant prognosis as in nonfearful patients (NF, control group). METHOD AND MATERIALS 15 DP with PDPT and 15 NF were treated with dental implants and were re-evaluated 2 to 4 years after denture-mounting regarding: alteration of dental anxiety (Hierarchical Anxiety Questionnaire [HAQ], Visual Analog Scale [VAS]), patient satisfaction and compliance, implant success, and peri-implant health. Statistical tests of non-inferiority DP versus NF were performed with Hodges-Lehmann estimators and respective one-sided 97.5% confidence intervals of Moses, and pairwise testings with Mann-Whitney test. RESULTS The DP test group rated its anxiety significantly lower at follow- up than at baseline (PHAQ < .001). However, at follow-up, anxiety was still higher in DP than in NF (PHAQ = .046; PVAS < .001). Implant success at follow-up was 100%. Oral health was equally good in DP and NF patients. At follow-up, all patients were satisfied with implant therapy, but compliance was better for NF (100%) than for DP (73% dental checkup; 67% dental hygienist). CONCLUSION Implant therapy can be successfully performed in DP patients with PDPT as phobia is not negatively influenced by the invasive implant therapy. However, motivation for professional maintenance programs remains challenging.
