Aim: To evaluate site-related changes in periodontal pocket depth (PPD) after non-surgical periodontal therapy and to identify predictors for PPD changes in a retrospective patient data analysis., Materials and Methods: PPD, clinical attachment level, bleeding on probing, tooth mobility (TM), furcation involvement (FI), abutment status, adherence to supportive periodontal care (SPC) and SPC follow-ups were obtained from fully documented patient data before periodontal therapy (baseline, T0), after active periodontal therapy (APT, T1) and during SPC (T2). PPD changes were classified into deteriorated or unchanged/improved at the site level. Multi-level logistic regression analysis was performed to identify factors influencing PPD changes during SPC., Results: This retrospective study included 51 females and 65 males (mean T0 age: 54.8 ± 10.1 years, 25 smokers, 12 diabetics) suffering from Stage III/IV periodontitis. Evaluation outcome: T0/16,044 sampling sites/2674 teeth; T1/15,636/2606; T2/14,754/2459. During 9.0 ± 2.3 years SPC, PPD decreased (-1.33 ± 0.70 mm) by 21.8% of the sites, remained unchanged by 41.4% and increased (1.40 ± 0.78 mm) by 36.8%. Distopalatal FI (p < .001, odds ratio [OR]: 0.252, 95% confidence interval [CI] for OR: 0.118-0.540), residual pockets (p < .001, OR: 0.503, 95% CI: 0.429-0.590) and TM Degrees I-III (Degree I: p = .002, OR: 0.765, 95% CI: 0.646-0.905; Degree II: p = .006, OR: 0.658, 95% CI: 0.489-0.886; Degree III: p = .023, OR: 0.398, 95% CI: 0.180-0.879) correlated significantly with increasing PPD., Conclusions: Over 75% of PPD remained unchanged or increased during SPC. Distopalatal FI, TM Degrees I-III and residual pockets after APT lead to worsening of periodontal pockets., (© 2024 The Authors.

Objective: This retrospective study aimed to evaluate tooth loss and the evolution of periodontal inflammatory parameters within a strict nonsurgically treated patient cohort with < 2 supportive periodontal care visits per year, defined as minimal periodontal basic care, of 2.5 to 10.7 years., Method and Materials: Data for nonsurgically treated patients were checked for: complete periodontal examination data at baseline (T0), after active periodontal therapy (T1), and after ≥ 2.5 years of supportive periodontal care (T2); smoking, diabetes mellitus, age (at least 18 years), plaque and gingival indices, bleeding on probing, percentage of residual pockets, supportive periodontal care adherence, and number of supportive periodontal care visits were assessed as risk factors for tooth loss., Results: In total, 132 patients were included (76 female, mean age 56.7 ± 10.3 years), mean T1-T2: 4.5 ± 1.6 years. 26.5% of all patients lost 118 teeth (0.5 teeth/patient, 0.12 teeth/patient/year). Plaque and bleeding parameters were: mean plaque control record, 59.77 ± 28.07%; mean Papilla Bleeding Index, 47.46 ± 34.12%; mean bleeding on probing, 33.46 ± 21.52%. Supportive periodontal care duration (P = .013) and T2 bleeding on probing (P = .048) were identified as patient-related risk factors for tooth loss., Conclusion: Minimal periodontal basic care was characterized by elevated bleeding on probing, Papilla Bleeding Index, and plaque control record scores. This possibly highlights a lack of consequent applied surgical intervention (if needed) transitioning into regular supportive periodontal care, including insufficient patient behavioral changes regarding domestic oral hygiene procedures and possibly nonaddressed proinflammatory dietary habits as a negative effect. An apparently low tooth loss rate could be observed. The duration of supportive periodontal care was identified as a risk factor for tooth loss.

Objectives: Plaque control by improved domestic oral hygiene is essential in periodontal treatment. However, changing treatment providers may interfere with building a dentist-patient relationship and in turn affect treatment success. The aim of this randomized, controlled, prospective short-term study was to determine the influence of either one or four different pre-graduate practitioners on patients' oral hygiene parameters during active periodontal therapy., Material and Methods: A total of 55 patients with periodontitis were allocated to two groups. Within the group "continuous treatment" (CT, n = 27), each patient was treated by one individual practitioner over the treatment period. For patients of the group "discontinuous treatment" (DT, n = 28), treatment in each session was performed by a different practitioner. Periodontal parameters (BOP, PBI, and PCR) were assessed at two timepoints: T1 (baseline) and T2 (end of active therapy)., Results: With CT, the PBI improved in 93% of the patients, compared to 71% with DT (p = 0.048). T1-T2 intragroup analysis showed a statistically significant improvement of all observed clinical parameters with no differences in ∆PBI, ∆BOP, and ∆PCR. Spearman's correlation analysis revealed a weak correlation between PCR and BOP of CT only., Conclusions: In the present study, improvement of all parameters was comparable between the groups. PBI, as a parameter displaying patient's domestic plaque control compliance, improved in more patients from CT than DT. This is possibly indicating an advantage of continuous treatment by one single practitioner., Clinical Relevance: Treatment by either a single practitioner or by multiple, constantly changing practitioners might influence patients' compliance to modify their behaviour when medically necessary., (© 2022.

Introduction: Aim of this study was to investigate the motives for studying dental medicine of pupils and students accepted for first semester., Methods: Motives of pupils from secondary schools (grades 10-12) around Tübingen and accepted students at the Dental School Tübingen were evaluated using a five-level Likert scale. Information about age, gender, family, apprenticeship and university enrolment was also included in the assessment., Results: A total of 402 out of 409 participants filled out the questionnaires. Of these, 390 (280 females and 110 males) could be evaluated; the mean age was 17.4 years. Sixty-one planned an apprenticeship and 64 already completed it; 93 were readily accepted at university. All participants highly rated the motives "help patients" and "good career prospects." As next, women chose "diversified activity" and men "scientific interest." Participants who planned an apprenticeship rated "help patients" significantly higher than the other participants, whilst the motive "high responsibility of the dental profession" amongst interviewees with completed apprenticeship was highly significant in comparison with the rest., Conclusion: Empathy for patients and high responsibility of the dental profession are more important than prestige or social standing. An apprenticeship seems to greatly influence the career choice by giving more weight to "high responsibility of the dental profession." In future, such results can help universities design selection tests to target specific groups. The high proportion of female dentists and the attitude towards work and family of the generations Y and Z may bring change to the traditional practice model in Germany., (© 2021 The Authors.

Purpose: The objective of this study, conducted in Germany, Finland and Turkey, was to identify whether motivations to study dentistry varied by country, gender or year of study., Methods: The multicentre pilot study was conducted in English language in 2014. Participants (n = 469 dental students) were either in the first or last year of study. The response rate was 91%., Results: The sample comprised 63% females and 37% males, reflecting the common gender distribution in dental education. A total of 236 first year students (50.3%) and 233 final year students (49.7%) took part in the study. The participants were aged 21-25 years and of 15 different nationalities, mostly from Turkey, Germany and Finland. Considering who motivated them most to become a dentist, the most common answer was "self-motivated" (49.5%). 23.4% of the students stated having been motivated by a "family member or friend, who is a dentist," while 24.3% said they had been motivated by a "family member or friend, who is not a dentist." -Very few students (2.8%) recorded having been motivated by a "high school or college counsellor." Motivations for choosing dentistry as a career included "ability to help people," "self-employment," "income potential," "working with hands" and "status and prestige," all of which were rated as highly important. "Time management" and "career variety" were rated as moderately important. Significant statistical differences were observed by country and gender. For the German students, a dental relative was significantly more often relevant than for the Finnish and Turkish students, who were more often influenced by family members or friends not working in the dental field. "Time management" seemed to be significantly more important to female than to male students., Conclusion: In line with a feminisation of the workforce in dentistry, a well-structured working environment and well-thought-out time management may play an increased role in future work force planning (Gender dentistry: International vergleichende Studie zu Karrierewahl und Spezialisierungswünschen von Zahnmedizinstudenten.
