    Abstract: The prevalence of dental caries in Romania remains high. The objective of this study is to analyse the link between dental caries, salivary pH and buffer capacity and the nutritional status in children. This cross-sectional study used a sample of 162 children, between the ages of 6 and 12 years, from Mures County, Romania. The prevalence of caries was measured using the decayed, missing, and filled teeth index for deciduous teeth (dmft index) and for permanent teeth (DMFT index). In addition, height and weight were assessed for each subject, and their body mass index (BMI) was calculated. The buffer capacity and the pH was determined after collecting stimulated saliva. Undernourished children presented a higher caries incidence and a lower salivary pH value compared with the normal weight and overweight children. Further longitudinal studies should be conducted in order to study the relationship between BMI, pH, dental caries and salivary buffer capacity. Future preventive programs should include nutrition control in order to prevent both the apparition of dental caries and of malnutrition.

    Abstract: According to titanium s much higher hardness and strength compared with the bone, if correctly applied, mini-screws will suffer no damage. Reusing orthodontic mini-screws would reduce treatment cost and lead to more use of mini-screws and improvement of orthodontic treatments. In this study, scanning electron microscopy (SEM) was used to assess structural variations of retrieved orthodontic implants and to evaluate the mechanical properties that may adversely affect stability of orthodontic implants. For analisys 10 self-drilling mini-implants retrieved after treatment, made from commercially pure (CP) alpha-titanium from two brands Leone, Italy and ForestaDent, Germany were analised using SEM according to the degree of morphological deformation of the head, transmucosal neck, threaded body, and tip of the implant at up to 10,000 x light magnification. The mini-implants did not present any defects such as bubbles, imperfections or fissures in their internal microstructure. No significant marks resulting from the manufacturing process were observed. Surface irregularities in the threaded body and tip (fig. 5-7) were observed and significant tip deformation was evident in the majority (80%) of retrieved mini-implants.

    In: Journal of Interdisciplinary Medicine, Walter de Gruyter GmbH, Vol. 6, No. 2 ( 2021-06-01), p. 103-107
    Abstract: Background: The differential diagnosis of endodontic and periodontal diseases can sometimes be clinically difficult, but it is vital to establish a correct diagnosis so that predictable treatment can be offered. Aim: The aim of this study was to highlight the prevalence of endo-periodontal lesions in the frontal dental group of the lower jaw depending on the degree of bone resorption as well as endodontic filling resorption in different patients, some of them with orthodontic treatment, using conical beam computed tomography (CBCT). Materials and methods: A number of 31 CBCT imaging volumes and the medical records of these patients were selected for analysis by an experienced examiner. The sites selected for analysis were divided into two subgroups, one where the endodontic treatment was performed with Endomethasone™ (Colthene, Creteil, France) (7 patients), and the other where it was performed with Adseal™ (Meta Biomed, Seoul, South Korea) (6 patients). Results: The mean age of the study population was 24.1 years, and 35.8% presented previous orthodontic treatment in their medical history. There were no statistically significant differences (p = 0.54) between groups regarding the length of the endodontic filling, the Endomethasone group showing a total length of 11.24 millimeters while the Adseal group showed a total length of 10.85 millimeters. Conclusions: The image obtained in clinical situations in which patients present combined endodontic-periodontal lesions is of real help because in many cases, with the help of CBCT, the starting point of a combined lesion can be highlighted, whether it is endodontic or periodontal.

    Abstract: Impression materials are used to record and reproduce the exact morphology of the patient’s oral cavity. The dimensional stability of a material is its ability to maintain the accuracy of recording the details of the oral cavity for a longer period of time, including the time during imprinting and immediately after. The aim of this study was to evaluate the accuracy of three different impression materials commonly used in the dental practice with the aid of an extra-oral three-dimensional (3D) scanner using an in vitro analysis. A typodont tooth model of the maxillary dental arch and mandibular dental arch, containing 16 permanent teeth, was used for evaluation. With the aid of three different impression materials, this model was imprinted fifteen times, resulting in fifteen different plaster models. A capsule extra-oral scanner device was used to digitalize the models and the same device was later used to align, compare, and measure scanned model surfaces. After performing the Kruskal–Wallis test for each measurement category (model), only two out of the fifteen measurements showed statistically significant differences between the material groups: vestibular-oral and mesial-distal width. Post hoc analysis showed that the alginate model (mean range = 29.13) had significantly higher bias scores than the addition silicone model (mean range = 16.75) (z = 2.501, p = 0.037). The difference between the average values of the model bias made from condensation-based silicone and addition-based silicone was initially significant, but after applying the Bonferroni correction for further comparisons, this relationship did not remain significant (z = 2.197, p = 0.084). Addition-based silicone models had the highest accuracy in terms of fidelity, followed by condensation-based silicones, and then by alginate models. Silicone-based impression materials improved over time, being highly used in all areas of dentistry. Alginate impressions had the lowest pattern of accuracy among those studied.

    Abstract: Digital impression devices are used alternatively to conventional impression techniques and materials. The aim of this study was to evaluate the precision of extraoral digitalization of three types of photosensitive resin polymers used for 3D printing with the aid of a digital extraoral optical scanner. The alignment of the scans was performed by a standard best-fit alignment. Trueness and precision were used to evaluate the models. The trueness was evaluated by using bias as a measure and the standard deviation was used to evaluate the precision. After assessing the normality of the distributions, an independent Kruskal–Wallis test was used to compare the trueness and precision across the material groups. The Mann–Whitney test was used as a post-hoc test for significant differences. The result of the analysis showed significant differences (U = 66, z = −2.337, p = 0.019) in trueness of mesiodistal distances. Upon visual inspection of the models, defects were noticed on two out of nine of the models printed with a photosensitive polymer. The defects were presented as cavities caused by air bubbles and were also reflected in the scans. Mean precision did not vary too much between these three photosensitive polymer resins, therefore, the selection of 3D printing materials should be based on the trueness and the required precision of the clinical purpose of the model.

    Abstract: Severe early childhood caries (S-ECC) is one of the most common pathologies affecting primary dentition. The complex etiology is the result of the interaction of microbial factors and also of dietary factors. For this study a group of 40 children diagnosed with S-ECC was compared with a control group of 35 children without caries. The study data was obtained through clinical examination of both children and mothers, and on the basis of a questionnaire completed by the mothers of the subjects. The odontal status of the mothers was evaluated by determining the DMFT index. The results of the study showed that the mothers of the subjects with S-ECC had a significantly higher DMF-T caries index than the ones in the control group and that there is a close link between the birth of the child, newborn feeding method, mother’s habits, cariogenic diet and the occurrence of severe early childhood caries.

    Abstract: Introduction: According to last years' research, periodontopathogens may have a negative impact on treatment options in patients with periodontal lesions. However, not all infected sites suffer periodontal destructions, which can be explained on the assumption that only a limited number of pathogens present in a sufficient amount, are capable of affecting the periodontal tissue. Thermal cycling polymerase chain reaction (PCR) is a new technique used for the identification and quantification of periodontopathogenic bacteria. The aim of our study was to confirm the presence of periodontal pathogens, and to evaluate the amount of microbacterial pathogens in the periodontal pockets of patients undergoing orthodontic treatment for a more predictable result. Material and methods: A total amount of 32 subgingival samples were collected from periodontal pockets ≥6 mm in 8 patients. Clinical examinations, periapical radiographs and periodontal screenings were performed. Only patients undergoing orthodontic treatment with fixed appliances were included in the study. PCR and DNA hybridization-based identification were performed by paper-point sampling using a micro-IDent plus, Hain Lifescience Germany kit. Results and Discussions: Results showed that bacterial load may be connected to disease progression. The prevalence of the periodontopathogenic bacteria Actinobacillus a. was established in 42.8% of cases, P. Gingivalis in 71.42%, P. Intermedia 57.14%, Bacteroides F . was found in 85.71% of cases, Treponema D . in 100% of cases. Extremely high bacterial loads were recorded for Actinobacillus a., Bacteroides F . and Prevotella I .

    Abstract: Introduction: Pain is currently reported as the most common side effect associated with orthodontic treatment. The aim of this study was to evaluate the factors associated with the intensity of pain perception during orthodontic procedures consisting in anesthesia, orthodontic mini-implant placement and removal, as well as during the postoperative period following these procedures. Material and Methods: The study included 50 young adults with a permanent dentition in need of orthodontic treatment. The pain assessment was based on visual analogue scale (VAS), using self-report questions from approved questionnaires. Pain severity was analyzed in relation to: anesthesia, implant placement, implant removal, implant movement, elastic traction and gingiva/bone pain around the implant. The study lot was divided into Group 1 – patients experiencing a pain degree of 1 or 2, and Group 2 – patients experiencing a pain degree of 3 or 4 during implant placement. Results: The maximum pain intensity (PI) was recorded during implant placement, which has been associated with a PI of 2.4 ± 0.8 (95% CI: 2.17–2.63), followed by implant removal (PI = 2.36 ± 0.66, 95% CI: 2.17–2.54), gingiva/bone pain around the implant (PI = 2.32 ± 2.58, 95% CI: 2.15–2.48), and elastic traction (PI = 2.26 ± 0.63, 95% CI: 2.08–2.44). Male gender was present in a significantly higher extent in the group of patients presenting a high intensity pain during implant placement (86.3% in Group 2 vs. 3.5% in Group 1, p 〈 0.0001). The age group most sensitive to pain was 18 to 21 years. Conclusions: In our study, pain perception was significantly higher in males and in the 18–21 years age group. The most painful procedure during surgery was the initial moment of implant placement, followed by the moment of implant removal, gingival/bone pain around the implant, and the elastic tractions placed on the implant during anchorage.

    Abstract: The use of maxillary expanders has the effect of distancing the maxillary bones at the level of the median palatal suture. During maxillary expansion, the main resistance forces occur at the zygomatico-maxillary sutures, and not in the median palatal suture, which is the basic principle on which this method is based. In this observational study, we evaluated possible complications at the skeletal and dentoalveolar level after palatal split using miniscrew-assisted rapid palatal expansion (MARPE) associated or not with corticopuncture (CP) therapy. The study included 27 patients with maxillary transverse deficiency and unilateral or bilateral cross-bite. Skeletal and dentoalveolar changes were evaluated using cone beam computed tomography (CBCT) images acquired before and after expansion. The mid-palatal suture was separated in 88.88% of cases, buccal bone height of the alveolar crest had decreased at first molar both at oral and palatal level by approximately 2.07 mm in 40.7% of cases whilst the remaining 59.3% showed insignificant bone loss, with canines exhibiting buccal tipping of 4.10° in 62.5% of cases. Changes of the occlusal planes were observed in 10 cases (37%). Maxillary canines tended to show symmetric buccal inclinations relative to the maxillary basal bone. Six patients; 22.22% showed hypertrophy/hyperplasia of the palatal mucosa associated with ulcerations, erythema, itching, and discomfort in the area. Swelling at the mid-palatal suture after split was observed in all cases and was caused by the resultant force. No cases of necrosis of the palatal mucosa were observed. Although occlusal modifications occur after palatal split, especially in unilateral cross-bite cases, these changes can be treated with the help of fixed orthodontic appliances.
