Aim of study was to compare the clinical visual and radiographic diagnostic technique with histological analysis of early proximal carious lesions. Materials and method. Study group included 96 proximal surfaces (48 teeth obtained from dental extractions for orthodontic or periodontal reasons). The proximal surfaces were examined by visual clinical examen and radiographic examen. A histological assessment was performed as gold standard. The sensivity and specificity values were calculated for clinical and radiographic examen. The values were analysed using McNemar test, with significance threshold p < 0.05. Results. Significant statistical differences were obtained when comparing both the sensitivity and specificity of the radiological detection method compared to the clinical method (p=0.0001

This article explores the impact of Sjögren's syndrome on saliva and its correlation with dental caries. Sjögren's syndrome is an autoimmune disease that affects saliva production and composition, increasing the risk of dental caries. The study found significant differences in dental and salivary health between patients with Sjögren's syndrome and a control group. It emphasizes the importance of oral hygiene and following dentist recommendations for caries prevention and treatment for individuals with Sjögren's syndrome. The document is a comprehensive list of references and citations related to Sjögren's syndrome and oral health, providing a thorough overview of current research on the topic.

This article from the Romanian Journal of Oral Rehabilitation discusses the clinical performance of resin composite restorations in posterior teeth. It reviews factors that influence the longevity of these restorations, such as patient-related factors, dental group, cavity size, and cervical margin extension. The article concludes that resin composites are the material of choice for minimal interventions in posterior teeth, and they demonstrate similar clinical performance to amalgam restorations in medium-sized cavities. The success of these restorations depends on various factors, including the restored tooth, materials and techniques used, patient risks, and clinical decisions. The text discusses the factors that contribute to the failure of posterior resin composite restorations in dental patients. Patient-related risk factors include high cariogenic risk, occlusal stress, periodontal status, smoking, dietary habits, and parafunctional habits. The type of resin composite used, adhesive systems, restorative technique, and isolation technique also play a role in the success of the restorations. The main reasons for failure are fractures within the restoration and secondary marginal caries. The text emphasizes the importance of using minimal interventions such as marginal sealing or refurbishment to extend the lifespan of the restorations. The overall success rate of posterior composite restorations is reported to be between 43.4% and 98.7%. It is suggested that resin composites may be inferior to amalgam in terms of cost-effectiveness. However, various research groups have reported satisfactory results with resin [Extracted from the article]

This article examines the effects of pretreating dentin with a 2% chlorhexidine solution and subjecting it to cariogenic attack on the marginal adaptation of glass ionomer cement (GIC) to dentin walls. The study found that pretreatment with chlorhexidine did not significantly affect the marginal adaptation of GIC to dentin, but cariogenic attack did have a negative impact on the interface between the material and dentin. The study emphasizes the need for further validation through in vitro and in vivo studies and provides insights for the use of GIC. [Extracted from the article]

Progress in understanding the etiopathogenesis of periodontal disease has led to a reconsideration of the importance of the role of different risk factors in disease processes. Risk factors act in a very personal way. The same set of risk factors that cause increased susceptibility to periodontitis in a person may have no effect on another person. Changing or eliminating a risk factor (eg smoking cessation) can alter the risk of disease or increase treatment success, whether or not known pathogenic mechanism. Numerous consistent evidence suggests the possible contribution of diabetes, smoking, and stress to periodontal destruction. The exact assessment of the risk factors for any condition depends on the degree of scientific or technical reproducibility and the validity of the diagnostic test used. Recently, attention has been paid to the risk assessment of periodontitis, mainly because the earlier paradigm regarding the etiology and progression of the disease implies an ubiquitous condition – gingivitis, which would lead to periodontitis. Conclusions. The concept of risk is a complex notion in permanent dynamic (risk factors / risk predictors). Dentists should be encouraged to communicate with general practitioners about the health of their patients, and general practitioners should be alerted to the possible risks of severe / aggressive forms of periodontal disease.

Surface roughness is the major contributor for extrinsic discoloration of resin composite restorations. This property is closely related to the organic matrix, inorganic filler composition of the composite, and finishing and polishing procedures. Rough surface greater than 0.2 µm provides higher chances of biofilm accumulation, leading to staining and/or discoloration of the restoration’s body or margins. The purpose of the study was to compare the finishing and polishing technique of some composite resins with their sealing using a glaze material type, in terms of surface roughness. Materials and methods: 45 composite specimens were manufactured( ormocer- ADMIRA, nanohybrid – TETRIC EVOCERAM, nanocomposite – FILTEK ULTIMATE), and divided into 3 groups(n=15, control, polished and finished, and glaze material). Roughness(Ra) was messured before and after immersing in artificial saliva. For all composite resins the sourface roughness decreased after 90 days.

This article discusses a study conducted on 50 patients from the Faculty of Dental Medicine in Romania to examine the effects of smoking on dental health. The patients were divided into five groups based on their smoking habits, ranging from non-smokers to heavy smokers. The study found that smoking more than 10 cigarettes per day or using electronic cigarettes significantly affected salivary flow rate, pH value, buffer capacity, and micro-crystallization index. Additionally, smokers of more than 20 cigarettes per day or electronic cigarette users had an increased number of decayed, missing, or filled teeth. The study emphasizes the negative impact of smoking on oral health and the development of dental caries. [Extracted from the article]

The study aimed to determine prevalence of incipient occlusal caries related to different cariogenic risk categories as well as the distribution of incipient occlusal caries accordingly to ICDAS classification and results of laserfluorescence examen. Material and methods. The study group included patients classified in low cariogenic risk (18 patients, 320 occlusal surfaces), medium cariogenic risk (65 patients, 320 occlusal surfaces) and high cariogenic risk (32 patients, 527 occlusal surfaces). 1960 occlusal surfaces were assessed using clinical examen (ICDAS system) and laserfluorescence method (DIAGNODENT, Kavo). Results. For the category of low cariogenic risk patients, most incipient occlusal caries are classified as code ICDAS 02 (11.56%) and 13.43% are recorded in the range of values 10-20 (enamel caries) accordingly to laserfluorescence examen. The patients with medium cariogenic risk present similar rates of incipient occlusal caries with codes ICDAS 02 (13,74%) and 03 (13,56%), as well as 20,20% occlusal surfaces recorded with values 10-20 in laserfluorescence method. The patients with high cariogenic risk present similar rates of incipient occlusal caries with codes ICDAS 02 (15,55%) and 03 (13,66%), as well as 18,78% occlusal surfaces recorded with values 10-20 (enamel caries) and 14,23% (dentinal caries) with values over 30, in laserfluorescence method. Conclusions. The rates of incipient occlusal caries, accordingly to ICDAS system and laserfluorescence examen, are also influenced by cariogenic risk category.

Introduction. The aim of study was to correlate dental-pulp reactions to dental caries with diverse localization, evolution and depth. Materials and method. The study was realized on a group of 87 patients with age ranging between 15-35 years. 222 posterior teeth with carious lesions were examined both on clinical and radiographs (ortopantomographs). Type of pulp-dentinal defensive reactions visible on radiographs were as follows: neodentinogenesis with advanced deposition of tertiary dentin, dentinal hypermineralisation, difuse pulp calcification. Parameters taken in study were as follows: sex, age group, dental group, radiographic indices (depth, location). Data were recorded in tables and expressed in Microsoft Excel graphs. Results and discussions. Clinical and radiographic data showed correlation between deep chronic caries localized on occlusal surfaces of mandibular molars and dentinal hypermineralisation reactions; deep chronic caries localized on maxillary molars were associated with massive retraction of pulp room through neodentinogenesis. Lack of pulp-dentinal complex reactions was observed especially for patients with age 15-25 and dental caries with acute evolution. Conclusions. Age, localization and evolution of dental caries can be correlated with presence of specific forms of pulp-dentinal reactions.

Introduction The COVID-19 pandemic situation forced governments to impose various measures to reduce the spread of the virus. The most used method is to wear facial masks, which can be found under several commercial forms. Wearing facial masks has caused a lot of controversy and rumors. Among them, many patients and practitioners have complained of a dry mouth after wearing different types of facial masks for a variable period of time. The aim of this study was to analyze the quantitative (un-/stimulated salivary flow rate) and qualitative (pH and buffer capacity) changes in saliva in mask wearers. Methodology Forty subjects were selected for this study. All of them wore alternatively no mask, a surgical mask for 2 hours, and FFP2 mask for 2 hours (groups 1, 2, and 3). Saliva samples were collected from all the subjects in the groups and analyzed to determine the values of un-/stimulated salivary flow rate, the pH, and buffer capacity using GC Saliva-Check Buffer (GC Corporation, Japan). Descriptive and analytical statistics were performed using ANOVA and Bonferroni post-hoc test. Results For unstimulated saliva samples, between groups 1 and 3, statistically significant differences were recorded, with a significance level of 0,02
