Remote assessment of dental records by using intraoral scan-based digital three-dimensional models in an elderly patient population - an exploratory study.

Aim: To assess the agreement rates of dental records derived from intraoral scan-based digital three-dimensional models (3DM) and 3DM + panoramic radiographs (3DM+PAN-X) compared to clinical findings.

Materials And Methods: Based on the 3DM/3DM+PAN-X of 50 patients undergoing supportive periodontal therapy (SPT), ten remote raters (inexperienced in using IOS or 3DM) assessed for each site of the dental scheme (32 sites) whether a tooth was missing (M), filled (F), restoration- and caries-free (H), replaced by an implant (I) or decayed (D). Remote records were compared to the clinical reference record of each patient at tooth-level.

Long-term stability of infrabony defects treated with enamel matrix derivative alone: A retrospective two-centre cohort study.

Aim: To assess the long-term stability of attachment gain in infrabony defects (IBDs) 10 years after regenerative treatment with an enamel matrix derivative (EMD) alone.

Materials And Methods: Two centres (Frankfurt [F] and Heidelberg [HD]) invited patients for re-examination 120 ± 12 months after regenerative therapy. Re-examination included clinical examination (periodontal probing depths (PPD), vertical clinical attachment level (CAL), plaque index (PlI), gingival index (GI), plaque control record, gingival bleeding index and periodontal risk assessment) and review of patient charts (number of supportive periodontal care [SPC] visits).

Remote assessment of DMFT and number of implants with intraoral digital photography in an elderly patient population - a comparative study.

Objectives: This comparative study aimed to evaluate intraoral digital photography (IODP) as assessment-tool for DMFT and number of implants (IMPL) compared to clinical diagnosis (CLIN) in an elderly population with high restorative status. Secondary research questions were whether an additional evaluation of panoramic radiographs (PAN-X) or raters' clinical experience influence the agreement.

Methods: Fifty patients (70.

Impact of the COVID-19 pandemic on oral health and psychosocial factors.

The objective of this study was to investigate oral health-related quality of life (OHRQoL) in times of the COVID-19 pandemic and to examine a possible association to psychosocial factors like psychological stress and symptoms of depression and anxiety disorders. Secondary research questions were whether people changed oral hygiene regimens during the COVID-19 pandemic and to what extent dental symptoms existed and developed compared to pre-pandemic. For this cross-sectional study a survey has been conceptualized to determine OHRQoL, stress, depression and anxiety and their specific confounders in a German cohort.

The impact of splinting timepoint of mobile mandibular incisors on the outcome of periodontal treatment-preliminary observations from a randomized clinical trial.

Objectives: To compare the outcome of periodontal parameters in mobile mandibular incisors which were splinted before or after full-mouth disinfection (FMD).

Materials And Methods: Thirty-four periodontitis patients with ≥ 1 mobile mandibular incisor (mobility degree II/III, clinical attachment loss (CAL) ≥ 5 mm, relative bone loss ≥ 50%) were randomly allocated to group A or B. Patients received periodontal treatment (PT) including splinting of teeth 33-43 before (A) or after FMD (B).

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

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

Material And Methods: Thirty-four periodontitis patients with ≥1 mobile mandibular incisor (degree II/III) were randomly allocated to the test or control group. All patients received FMD and the test group additional splinting of teeth 33-43.

Refractory neutrophil activation in type 2 diabetics with chronic periodontitis.

Background: Inflammation increases diabetes mellitus type 2 (T2DM) progression and severity. T2DM patients are at high risk of the rapid development of chronic periodontitis (CP). Topical presence, high numbers, and bactericidal effects of immune cells are challenged by augmented antigen-induced inflammation, which promotes both diseases.

Adherence to long-term supportive periodontal therapy in groups with different periodontal risk profiles.

Aim: To examine changes of the periodontal risk assessment (PRA) of patients during long-term supportive periodontal therapy (SPT) and to examine the adherence to recommended visit intervals.

Material And Methods: Retrospective data from 372 SPT patients were evaluated before and after active periodontal therapy (APT) and at least 5 years later. After APT and regularly during SPT, PRA was performed for all included patients (low-risk/moderate-risk/high-risk profile) and they were advised to adhere to 3/6-/or 12-month intervals accordingly.

Oral health-related quality of life in patients under supportive periodontal therapy.

Objective: To assess the oral health-related quality of life (OH-QoL) in patients under supportive periodontal therapy (SPT) and the influence of the individual periodontal risk as well as different degrees of adherence during SPT on OH-QoL.

Materials And Methods: 309 patients with at least 5 years of SPT were re-examined. Periodontal risk profile (according to Lang and Tonetti) was assessed and the adherence to SPT-appointments within the last 30(±6) months was reviewed for each patient (fully adherent: adherence to all appointments ±6 weeks, partially adherent: SPT-interval not extended more than half of the recommended interval, insufficiently adherent: SPT-interval extended more than half of the recommended interval, non-adherent: recommended SPT-interval interruption ≥12 months).

Long-term stability of splinted anterior mandibular teeth during supportive periodontal therapy.

Objective: The aim of the study was to retrospectively assess the survival rate and stability of periodontally compromised and mobile anterior mandibular teeth after splinting in patients under supportive periodontal therapy (SPT).

Materials And Methods: Thirty-nine patients with splinted anterior mandibular teeth and SPT (≥1 visit/year) for 3-15 years were re-examined. Periodontal status, patient and tooth-related factors were assessed retrospectively before (baseline) and 3 years after splinting (n = 39 patients, 162 splinted teeth).

Local inflammatory reactions in patients with diabetes and periodontitis.

The impact of diabetes mellitus on the prevalence, severity and progression of periodontal disease has been known for many years and intense efforts have been made to elucidate the underlying mechanisms. It is widely reported that hyperglycemia causes numerous systemic changes, including altered innate immune-cell function and metabolic changes. The aim of this review was to summarize and discuss the evidence for mechanisms that probably play a role in the altered local inflammatory reactions in the periodontium of patients with diabetes, focusing on local changes in cytokine levels, matrix metalloproteinases, reactive oxygen species, advanced glycation end-products, immune-cell functions, the RANKL/osteoprotegerin axis and toll-like receptors.
