Materials and methods: Thirty 2mm x 2mm x 25mm specimens of Tetric N-Flow (TNF), Filtek Bulk Fill Flowable Restorative (FBF) and Beautifil Flow Plus F00 (BFP) flowable resins were made up; they were distributed into three groups according to brand (n=10) and stored in distilled water for 24 hours at 37ºC. The 3-point bending test according to ISO 4049 was performed on a universal testing machine at a speed of 0.5 mm/min until fracture. The results were evaluated with Anova and Tukey tests. P&lt;0.05. Results: Statistically significant differences were found between the groups with a value of p=0.011. According to the statistical analysis, the groups that showed statistically significant differences were the BFP and TNF groups (p=0.015) and the BFP and FBF groups (p=0.035), while no statistically significant difference was found in the TNF and FBF groups. Conclusion: The high-filled flowable resin presents better flexural strength compared to the conventional flowable and bulk fill flowable resins, while the conventional and bulk fill flowable resins have no statistically significant difference.</p> Edith Liliana Sulca Gonzales, Ana Isabel López-Flores Copyright (c) Tue, 26 Sep 2023 00:00:00 -0500 Stafne’s bone cavity in a venezuelan population. Prevalence study <p>Objective: To determine the prevalence of the Stafne´s bone cavity in a Venezuelan population and to characterize it radiographically. Method: Descriptive and cross-sectional study. Of 500 panoramic radiographs, those that had radiolucent images in the mandible, circumscribed and not associated with any dental organ, as well as those that could correspond to the mandibular fossa, were selected. Results were collated and discrepancies resolved by consensus. The selected ones were characterized radiographically. The variables were compared using the student's t test for equality of means, applying the Levene test, values of p &lt;0.05 were considered statistically significant. Results: Of the 500 radiographs evaluated, 22 presented images corresponding to deep mandibular fossa or Stafne bone cavities, which represented 4.4%. Of which 5 presented bilaterally (22.7%) and 17 (77, 3%) unilocularly. Among the radiographic characteristics studied, images located in the posterior area (81.81%), without sclerosis (54.54%), continuous to the basal mandibular area, round shape (59.09%) and partial radiolucency (72%) were presented with a higher prevalence). They were more common in male patients with 63.63%. Conclusions: Our results show a higher prevalence of Stafne's bone cavity in a Venezuelan population than that reported in other studies in other populations.</p> Sabrina Visicchio Cusati, Carlos Manresa Bruguera, Valeria Gallego Mengod, Mariana Villarroel-Dorrego Copyright (c) Tue, 26 Sep 2023 00:00:00 -0500 Patterns of hypercementosis and their relationship with possible local etiological factors in radiographs of individuals from a mexican population <p>Objective: Hypercementosis (HPC) is an asymptomatic pathology that, according to the existing literature, has a low prevalence, there is a lack of information and research on it, within these studies, few are made by ethnic groups. To determine the prevalence and radiographic patterns of this condition, as well as the analysis of the relationship of the pathology with some of what are considered possible local triggering factors (FDL) in Mexican individuals. Methodology: 1193 orthopantomographies (OPG) were analyzed, randomly selected from patients of both sexes, with a chronological age range between 18 and 90 years, identifying the prevalence of HPC, as well as its relationship between age groups, its morphological patterns (focal, diffuse and sleeve-shaped), its distribution by anatomical region and dental organs (ODs) and the association of its presence with possible local triggering factors. Results: 348 DO with HPC were found in a total of 194 patients (16.30%), with no relevant differences between genders (P&gt; 0.05). There was a significant increase with respect to the presence of HPC in relation to the increase in the age of the patients (P= 0.001), finding it present in 10% of the age group &lt;40 years, in 20.30% in the group of 40 to 60 years and &gt; 60 in 30.20%. It was found more frequently in a diffuse form (75.28%), followed by the focal pattern (19.54%) and finding the sleeve-shaped morphology less common (5.17%). The mandible presented the greatest number of ODs with the presence of HPC, 136 (39.08%), with the left side being the most affected with 86 OD. The dental group with the greatest involvement was that of molars and premolars. Conclusions: The prevalence of hypercementosis was 16.30% in the Mexican individuals evaluated. Its presence increases as the age of the patients advances. Its main location is the mandibular region with a predilection for premolars and molars. Even though the idiopathic origin is the most frequent, it was observed that dental impaction is a possible local triggering factor.</p> María Alejandra Bernal Ruiz, Gustavo Adolfo Fiori Chíncaro Copyright (c) Wed, 27 Sep 2023 00:00:00 -0500 Temporomandibular manifestation in patients with Ehlers-Danlos syndrome: a systematic reviewEspañol <p>Introduction: Ehlers-Danlos Syndrome (EDS) consists of a group of diseases that imply a disorder among individual connective tissue due to an altered collagen production. Fibrocartilaginous structures, support ligaments, disc and retrodiscal from the temporomandibular joint are composed primarily of collagen. Objective: Identify TMJ manifestations in patients with different types of EDS. Materials and Methods: a systematic review of the literature was performed on PubMed, Scopus and Web of Science databases. Observational studies and case series reports published either in Spanish or not Spanish were included up until January 2023. Results: 12 articles met the inclusion criteria. The prevalence of temporomandibular disorders varies from 26.6% to 100%, being EDSh the most reported subtype, whereas disc displacement with or without reduction and joint hypermobility were the most reported joint disorders. Conclusion: Temporomandibular pathologies are common in patients with EDS, especially in those with the EDSh subtype.</p> Español Español, Felipe Soto , Sebastián Martinez, Españ E Copyright (c) Wed, 27 Sep 2023 00:00:00 -0500 Early orthodontic/orthopedic treatment in patients with class II sagittal anomalies. A review. <p>Introduction: Class II sagittal anomalies have a prevalence of between 18-32% of the population. To resolve this type of malocclusion, various therapies have been proposed, some of which involve functional orthodontic or orthopedic appliances. However, it is still a matter of discussion whether the treatments should be started at an early age in patients, or if there are adverse effects that could harm structures of the stomatognathic system. Objective: To analyze the results obtained from early treatment in patients with Class II sagittal malocclusion through a literature review. Materials and methods: An advanced search with terms and connectors was carried out in the Medline via Pubmed and Science Direct databases. Inclusion and exclusion criteria were applied for the definitive selection. Results: Through this search, a total of 5909 articles were collected, of which 23 were considered to meet the criteria established in this review work. Conclusions: There are orthodontic/orthopedic devices aimed at solving the characteristics of class II sagittal malocclusions, but before planning early treatment it is essential to provide an accurate diagnosis to evaluate the specific type of appliance that is required.</p> Christian Yanez-Zurita, Blanca Naranjo Freire, Arístides Martillo Chiriguaya Copyright (c) Wed, 27 Sep 2023 00:00:00 -0500 Effects of orthopedic treatment on temporomandibular joint in class III patients with anterior crossbite: a literature review. <p>Objective: The study aimed to evaluate the effects of orthopedic treatment on the temporomandibular joint (TMJ) in class III patients with anterior crossbite. Materials and Method: Four databases were reviewed until December 2022 (Scopus, PubMed, Embase, and Science Direct). Two independent reviewers selected studies reporting TMJ changes and the presence of TMJ dysfunction in Class III patients with anterior crossbite who received orthopedic treatment. The methodological quality of the studies was analyzed using the PRISMA checklist. Results: Twelve articles were selected for the study after a detailed search according to the selection criteria. Post-treatment studies demonstrated a low prevalence of TMJ pain after using the Delaire face mask, chin rest, modified Jasper Jumper, and fixed reverse Twin block. After treatment with reverse Twin block, an increase in condylar volume and joint spaces (p&lt;0.001) was observed, followed by a significant decrease in posterosuperior joint spaces (p&lt;0.001). Conclusions: Not enough evidence has been found to determine the presence of TMD or TMJ changes after using orthopedic devices for anterior crossbite correction.</p> Karen Moscoso Sivirichi, Roxana Gissella Gutiérrez Tapia Copyright (c) Wed, 27 Sep 2023 00:00:00 -0500 Skeletal maturation of the hand and wrist and ossification of the mid palate suture in adolescents: a literature review. <p>Introduction: The evaluation of skeletal age is an important factor in orthodontic planning to anticipate changes in growth, with the analysis of hand and wrist radiographs showing the degree of bone and facial growth potential. The objective was to evaluate the relationship between skeletal maturation of the hand and wrist and ossification of the midpalatal suture (MPS) in adolescents. Materials and methods: A search was carried out in four databases such as Pubmed, Scopus, Science Direct and Embase were reviewed until December 13, 2022. The included studies were descriptive and comparative articles on the skeletal maturation of the hand and wrist and ossification of the midpalatal suture of patients aged 7 to 18 years. Two researchers carefully selected the articles evaluated and analyzed the different key topics related to the topic. Results: Four articles were included in this study; According to the studies, it was found that the greater the degree of bone maturation there is an increase in the approximation of the SMP, especially in late stages, with high and positive correlations; Furthermore, there were greater evaluation results with the Fishman analysis method as opposed to the Hagg and Taranger and Björk methods. The critical limit stages in SMI7-9, a greater approach to the closure of SMP compatible with stage D-E was found. The completion of maturation in women occurs up to 2 years earlier than in men. Conclusions: Diagnostic evaluation methods using carpal analysis can be used for predictive evaluations of the maturation stage of SMP; However, the results were not absolute in all cases so they cannot be generalized.</p> Ruth Elizabeth Ramirez-Diaz, Gustavo Adolfo Watanabe Kanno Copyright (c) Wed, 27 Sep 2023 00:00:00 -0500 Characteristics of white spot lesions associated with orthodontic treatment: a review <p>Introduction: The purpose of this literature review is to provide scientific evidence on the characteristics of white spot lesions (WSL) during orthodontic treatment, their incidence, prevalence, risk factors related to their development, progression, and regression, as well as explain the most used diagnostic methods. Materials and methods: An exhaustive search was carried out in the databases of Pubmed, Scopus, Science Direct and Embase up to the date of November 30, 2022. Cross-sectional studies that evaluated white spot lesions before and after orthodontic treatments were included. Two researchers carefully selected the articles evaluated and analyzed different key topics on the subject. Results: It was found that the prevalence and incidence of white spots during orthodontic treatment varies widely depending on the diagnostic method used, the type of orthodontic technique used and the time of orthodontic treatment. The incidence of white spot lesions is highest in patients treated with conventional braces, followed by those who used self-ligating braces, and was lowest in patients who used aligners. The most affected teeth are the upper lateral incisors and upper maxillary canines at the level of the gingival third. Conclusions: The incidence of white spots is associated with orthodontic treatment, being closely related to the treatment technique used and the treatment time. There is a regression of the LMB during the first year after removal of the appliance.</p> Michella Vicenza Consoli Senno, Julissa Janet Robles Ruíz Copyright (c) Wed, 27 Sep 2023 00:00:00 -0500 Associated factors and types of eye injuries occurring in dentistry practice: systematic review <p>Introduction: The dentist and auxiliary personnel are in constant risk of occupational diseases such as: allergies, infections, skin or eye injuries; that could affect patients. A problem of social interest are the ocular injuries that occur to dental personnel. The literature reveals the prevalence of eye injuries in dental practice that are associated with solid particles, fluid splashes. Our objective was, through a systematic review, to review the types of ocular injuries and their associated factors that occurred in dental practice. Material and Methods: The relevant studies were searched in the databases: PubMed, Scopus, Ebsco, among others. The search included cross-sectional studies that evaluated the evidence on ocular injuries occurring in dental practice, excluding literature reviews, letters to the reader, and editorials. Results: Eight studies were included to develop the systematic review; determining that the associated factors of ocular injuries occurred in dental practice are: a) occasional use of ocular protection b) age c) sex d) years of practice and the types of ocular injuries are the entry of liquids and foreign bodies. Conclusions: Deficiency in compliance with eye or facial protection protocols in dental practice, cause eye injuries; Type of fluid entry, foreign bodies, splash of biological fluids or conjunctivitis. These eye injuries are generated from associated factors such as the occasional use of eye protection, age, sex, and others.</p> Jordi Abanto Sheron, Martín Andrés Chávez Méndez Copyright (c) Wed, 27 Sep 2023 00:00:00 -0500 Changes in the position and inclination of the upper incisor and upper lip postorthodontic treatment: case reports <p>Objective: To determine the changes in the position and inclination of the upper incisor and upper lip after orthodontic treatment in a series of 3 clinical cases. Materials and Methods: The three reported clinical cases correspond to adult patients who were treated with fixed orthodontics and premolar extractions. Measurements of upper incisor position (UIP), upper incisor inclination (UII), upper lip position (ULP), and upper lip inclination (ULI) were performed on pre-treatment and post-treatment cephalometric radiographs for assessment of changes. Results: In the first case a variation of -1 mm was found for both the UIP and the ULP, as well as a variation of the UII and the ULI, although in different magnitude. Case 2 presented a 2 mm variation in the UII with minimal changes in the upper lip (Δ ULP = 0 mm and Δ ULI =-0.5 mm) and in case 3 a 2 mm variation was obtained for both IIS and ILS. Conclusions: The results obtained in this case reports show us a wide variability, so it is impossible to accurately predict changes in soft tissues as a response to tooth movement. Clinical significance: Predicting tooth movement changes in soft tissues is critical during the initial planning phase of orthodontic treatment.</p> Alicia Chacón Moreno, Nelly Huasco Huarcaya Copyright (c) Wed, 27 Sep 2023 00:00:00 -0500
