AIM: To investigate whether long-term obesity, long-term central obesity and weight gain are associated with alveolar bone loss. MATERIALS AND METHODS: A sub-population (n = 1318) of the Northern Finland Birth Cohort 1966 was categorized based on body mass index (BMI: normal weight, overweight and obesity) and waist circumference (WC: no central obesity, central obesity) at ages 31 and 46. These categories were combined to define whether the participants stayed in the same categories or passed on to a higher category (weight gain)...

AIM: The aim of this systematic review was to evaluate the efficacy of patient-performed or administered adjunctive measures to non-surgical peri-implantitis therapy in terms of probing depth (PD) and/or bleeding on probing (BoP) reductions. MATERIALS AND METHODS: Randomized and controlled clinical trials with at least 6 months of follow-up were searched in three databases. Secondary outcomes included implant loss, disease resolution, recurrence of peri-implantitis, need of re-treatment, changes in marginal bone levels, patient-reported outcomes and adverse effects...

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...

AIM: To evaluate the microbial colonization in different dentition phases on individuals from 0 to 18 years of age belonging to families with a history of periodontitis compared to descendants of periodontally healthy parents. MATERIALS AND METHODS: The offspring of subjects with periodontitis ('Perio' group) and the offspring of periodontally healthy subjects ('Healthy' group), matched for gender and age, were included in this cross-sectional study and divided according to the dentition phase: pre-dentate, primary, mixed and permanent...

AIM: This randomized controlled trial aimed to investigate the efficacy of soft-tissue augmentation (STA) with a subepithelial connective tissue graft (SCTG) or an acellular dermal matrix (ADM) on reducing tissue alterations at an immediate implant site. MATERIALS AND METHODS: This trial had three groups: (i) immediate implant with SCTG (ICT group); (ii) immediate implant with ADM (IAD group); (iii) immediate implant without STA (control group). Forty-six patients were randomly assigned to each group...

AIM: To investigate whether there is an association between subgingival microbial diversity and reduced respiratory function. MATERIALS AND METHODS: A group of dentate 58-72-year-old men in Northern Ireland had a comprehensive periodontal examination including subgingival plaque sampling. DNA was extracted from plaque samples and the V1-V3 regions of the 16S rRNA gene were analysed by high-throughput sequencing and a microbial diversity index (MDI) was derived. Spirometry measurements were made using a wedge bellows spirometer...

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)...

AIM: To evaluate the association between lifestyle behaviours and clinical periodontal outcomes following Steps 1/2 of periodontal therapy. METHODS: A total of 120 subjects with untreated Stage II/III periodontitis participated in this study. At baseline, questionnaires were administered to assess the following lifestyle behaviours: adherence to Mediterranean diet (MD), physical activity (PA) and stress levels, sleep quality, smoking and alcohol use. Participants received Steps 1/2 of periodontal therapy and were re-evaluated after 3 months...

AIM: To investigate whether silibinin impacts diabetic periodontitis (DP) via mitochondrial regulation. MATERIALS AND METHODS: In vivo, rats were divided into the control, diabetes, DP, and DP combined with silibinin groups. Diabetes and periodontitis were induced by streptozocin and silk ligation, respectively. Bone turnover was evaluated by microcomputed tomography, histology, and immunohistochemistry. In vitro, human periodontal ligament cells (hPDLCs) were exposed to hydroxy peroxide (H2 O2 ) with or without silibinin...

AIM: This study investigated the existence of a bidirectional temporal relationship between periodontal condition and glycemic status. MATERIALS AND METHODS: This longitudinal study included 2,198 participants with mean age 43.4±7.7 years, who underwent dental examinations in Yokohama, Japan at two-time points, 2003-2004 and 2008-2009, at an interval of five years. Periodontal condition was assessed by the mean value of probing pocket depth (PPD) and clinical attachment level (CAL)...

AIM: To compare the salivary proteomic profile of periodontitis-affected (PA) parents and their offspring to periodontally healthy (PH) dyads in the pursuit of possible biomarkers for early diagnosis of this disease. MATERIALS AND METHODS: Unstimulated saliva samples collected from 17 pairs of PA or PH individuals and their children were submitted to mass spectrometric analyses followed by proteomic analyses. Primary PA fibroblasts were triggered towards having an inflammatory response, and an immunoenzymatic assay of its supernatant was performed to validate the obtained data...

AIMS: To analyze the histologic structure and histomorphometric characteristics of human hard palatal mucosa in order to determine the donor site of choice for connective tissue grafts from a histological point of view. MATERIAL AND METHODS: Palatal mucosa samples from six cadaver heads were harvested at four sites: incisal, premolar, molar and tuberosity. Histological and immunohistochemical techniques were performed, as was histomorphometric analysis. RESULTS: In the current study we found that the density and size of cells was higher in the superficial papillary layer, whereas the thickness of the collagen bundles increased in the reticular...

AIM: To reveal the heterogeneity of ex vivo-cultured human mesenchymal stromal cells derived from either masticatory or lining oral mucosa. MATERIALS AND METHODS: Cells were retrieved from the lamina propria of the hard palate and alveolar mucosa of three individuals. The analysis of transcriptomic-level differences was accomplished using single-cell RNA sequencing. RESULTS: Cluster analysis clearly distinguished between cells from the masticatory and lining oral mucosa, and revealed 11 distinct cell sub-populations, annotated as fibroblasts, smooth muscle cells or mesenchymal stem cells...

AIM: to evaluate associations between oral hygiene and gingival abrasion (GA) in a rural population from southern Brazil. MATERIALS AND METHODS: A population-based sample representative of individuals from a rural community in southern Brazil was included. Individuals aged 15 years or older and who had 5 teeth or more present were selected for this analysis. GA extent was defined as the total number of abrasions per individual. An adjusted multilevel negative binomial regression analysis was used to investigate the associations between site-, tooth-, and individual-level variables and GA...
