Background: Oral hygiene is essential for low caries or gingivitis prevalence in children. This study aimed to determine the oral hygiene profile of children from secondary schools (10–17 years) in Bucharest, Romania, and to explore options for preventing their future oral diseases. Methods: The study was cross-sectional, with a sample of n = 1595 pupils. The sample was stratified by clusters in city areas, grades, and the criterion of the presence/absence of in-school dental service. Dental check-ups were performed by using a commune dental examination kit. The oral hygiene simplified index (OHI; Silness and Löe) was used to assess the children’s oral hygiene status. Five questions were used to determine oral hygiene habits. Results: The mean value of the OHI was 1.04. Some differences in oral hygiene scores were found for different socioeconomic variables, such as parents’ education (p < 0.05): parents with vs. without a university degree—0.95/0.94 (male/female) vs. 1.06. Most of the children used manual toothbrushes (88%). Conclusions: The analysis of objective data (OHI) revealed a good level of oral hygiene, with many socioeconomic disparities.

Periodontal disease is a widespread chronic condition linked to systemic illnesses such as cardiovascular disease, diabetes, and adverse pregnancy outcomes. Despite its global burden, population-specific studies on its risk factors remain limited, particularly in Central and Eastern Europe. The SANA-biome Project is a cross-sectional, community-based study designed to investigate the biological and social determinants of periodontal disease in Romania, a country with disproportionately high oral disease rates and minimal microbiome data. This protocol will integrate metagenomic, proteomic, and metabolomic data of the oral microbiome from saliva and dental calculus samples with detailed sociodemographic and lifestyle data collected through a structured 44-question survey. This study is grounded in two complementary frameworks: the IMPEDE model, which conceptualizes inflammation as both a driver and a consequence of microbial dysbiosis, and Ecosocial Theory, which situates disease within social and structural contexts. Our aims are as follows: (1) to identify lifestyle and behavioral predictors of periodontal disease; (2) to characterize the oral microbiome in individuals with and without periodontal disease; and (3) to evaluate the predictive value of combined microbial and sociodemographic features using statistical and machine learning approaches. Power calculations based on pilot data indicate a target enrollment of 120 participants. This integrative approach will help disentangle the complex interplay between microbiological and structural determinants of periodontal disease and inform culturally relevant prevention strategies. By focusing on an underrepresented population, this work contributes to a more equitable and interdisciplinary model of oral health research and supports the development of future precision public health interventions.

Peri-implant infective diseases seem to be the most common cause for the late dental implant failure. Therefore, peri-implant microbiota has been intensively studied in modern implantology. Many studies showed a presence of extremely varied microflora in cases of peri-implant infective diseases. The main scope of this observational single-blind study was to analyze the presence of some microbial species in a group of patients with clinical signs of peri-implant mucositis compared to two other groups (patients treated with dental implants but without any clinical signs of peri-implant inflammation and patients treated with no dental implants). The identification of microorganisms was followed by an antibiogram in order to find their sensitivity to various antibiotics. The results showed a microbiota not necessarily specific for each situation (peri-implant infective diseases, healthy tissues around dental implants and healthy natural teeth and gums) with species like Candida albicans, Neisseria mucosa, Prevotella, Staphylococcus aureus, Streptococcus and others. Peri-implant infective diseases presented more bacterial species than other conditions.

Background and objectives: Studies report a more precarious oral health status, with a higher prevalence of periodontal disease, in hemodialysis patients. Also, oral inflammation foci, mainly periodontal disease, are related to systemic inflammation and malnutrition which have a negative impact on morbidity and mortality in these patients. The aim of this study is to observe the influence of dental on the general status of these patients. Material and Methods: The study is a series of cases and was conducted in two phases: data collection and treatment phase and monitoring phase. Dental treatment was performed on 13 patients, with ages between 43-69 years of age, diagnosed with moderate or severe periodontal disease. Oral status parameters (plaque and gingival bleeding index, pocket depth, attachment level, DMFT and CPITN index) and general parameters (C-reactive protein, albumin, hemoglobin, calcium phosphate product, calcium and phosphate levels, erythropoietic-stimulating agents) were registered and monitored. Conventional periodontal treatment, dental extractions, endodontic treatments were performed. Results: Oral assessment showed a statistically significant improvement of oral parameters, at both 1 month and 3 months post-treatment. Mean values for albumin, C-reactive protein, hemoglobin, calcium phosphate product and calcium levels had a slight improvement, but the difference was not statistically significant. Conclusion: The oral status, characterized by the measured periodontal parameters, improved visibly and statistically significant after the dental treatment. The parameters of the general status did not change significantly following the intervention.
