In the oral cavity, lymphomas can affect the jaws or soft tissues as the primary manifestation. We present a case of mandibular lymphoma with the aim of studying its clinical features, radiographic appearance, and histology.

Dear Editor, Dental aesthetics have become one of the main factors influencing social interactions [1]. More and more patients are seeking dental consultations with the desire to achieve a more attractive smile, as it is perceived as more appealing and welcoming in today’s society [2]. During academic training in dentistry, it is essential for professionals to acquire knowledge and skills in dental aesthetics in order to deliver better results in aesthetic procedures and become more competitive in the job market. However, in some academic institutions, dental aesthetics is not thoroughly covered, and for that reason, professionals must pursue continuous theoretical and practical education to enhance their learning. One effective alternative is continuing education through participation in specialized and advanced diploma programs. These programs offer numerous advantages to dentists, ranging from professional development to improved quality of patient care [3]. Diplomas in dental aesthetics represent a key tool for professional development, particularly in enhancing manual skills [4]. Dental aesthetics go beyond theoretical knowledge of dental anatomy, color, and facial aesthetics; it demands high precision and technical proficiency. Throughout these diploma programs, dentists have the opportunity to stay updated on the latest scientific and technological advances in materials and clinical techniques [3], such as the use of aesthetic materials, veneer placement, and dental restorations. These programs provide a learning environment where professionals can refine their skills through the use of simulators and model-based practice, allowing them to experiment and correct errors without the pressure of working directly on real patients. Constant practice and specialized training help dentists gain greater confidence in their abilities, reduce anxiety associated with complex procedures, and ultimately enable them to offer higher-quality and more aesthetic treatments to their patients. Furthermore, diplomas in dental aesthetics foster a collaborative learning environment where dentists can discuss complex cases and share experiences with colleagues and specialists. This contributes to the development of critical thinking and the ability to effectively manage a wide range of clinical situations. In this way, diploma programs not only improve technical skills but also promote professional growth through collaboration and knowledge exchange. Moreover, dentists who have completed a diploma in dental aesthetics are better equipped to positively impact their patients’ self-esteem and confidence, particularly in social interactions. A proper representation of features such as the color, shape, size, position, and visibility of the teeth can have a significant psychosocial impact on individuals’ lives, enhancing their confidence and quality of life [5]. These reasons highlight the importance of continuing professional education, especially considering the growing demand for aesthetic treatments among patients [6]. In recent years, aesthetic treatments in restorative dentistry have made significant progress. Traditional techniques are increasingly being replaced by digital dentistry due to the many advantages it offers. These include minimally invasive procedures, faster execution, simplicity, predictable outcomes, and better fit compared to traditional methods [7]. Therefore, it is essential for dentists to update their knowledge through aesthetic-focused diploma programs to master these new techniques and ensure optimal clinical results.

Introduction: Oral diseases, such as dental caries, periodontal diseases and their consequences, represent a global public health problem due to their high prevalence. Functional dentition, defined as having at least 21 natural teeth present in the mouth, is a key indicator of oral health and overall well-being. Objective: To evaluate the prevalence of functional dentition (FD) and analyze its association with sociodemographic, clinical and behavioral variables in Mexican adults treated at clinics of a public university. Methods: A cross-sectional study was conducted with 277 consecutive patients. Clinical examinations were performed by dental students under faculty supervision. FD was defined as ≥21 natural teeth and served as the dependent variable. Through clinical examination and questionnaires, data were collected on age, education level, systemic diseases (diabetes, hypertension) and smoking habits. Statistical analysis included Mann-Whitney and Chi-square tests using Stata 14. Results: The mean age was 47.6±15.5 years, and 65.7% were women. The prevalence of FD was 87%. Patients without FD were significantly older (61.2±11.5 vs. 45.6±15.0 years; p<0.0001) and had lower education levels (6.8±4.4 vs. 9.3±4.4 years; p=0.0027). No significant differences were found by sex, systemic diseases or smoking habits (p>0.05). Conclusions: FD was significantly associated with younger age and higher education levels, but not with comorbidities or smoking habits. These findings highlight the need for interventions targeting older adults and populations with low formal education to preserve functional oral health.

Introduction: Dental caries remains one of the most prevalent pathologies worldwide, affecting the health, nutrition, and psychosocial well-being of the pediatric population. In Ecuador, its high incidence is associated with social inequalities and limited preventive strategies. Although the use of fluorides is an effective tool for its control, the lack of knowledge regarding their proper use has contributed to an increase in dental fluorosis, particularly in rural areas. Objective: To identify the knowledge, attitudes, and practices regarding oral health, fluorides, and dental fluorosis among parents of children aged 5 to 12 years in two Ecuadorian communities with distinct sociocultural characteristics. Materials and Methods: An observational, cross-sectional study was conducted in Salasaka and Cayambe, involving 183 parents selected through convenience sampling. A structured questionnaire was applied, addressing sociodemographic variables, knowledge, attitudes, oral hygiene practices, and fluoride use. Data were analyzed using descriptive statistics and non-parametric tests. Results:The highest proportion of participants demonstrated an intermediate level of knowledge and practices concerning oral health, with better outcomes in Salasaka. A significant relationship was identified between knowledge level and locality (p=0.000). However, no significant differences in knowledge about fluorides were found between communities, highlighting a generally low level of information. Conclusions:The study reveals significant deficiencies in fluoride-related knowledge in both communities, despite differences in general oral health knowledge. It is recommended to implement culturally adapted oral health education programs that include information on the safe use of fluorides and the prevention of dental fluorosis.

Combination Syndrome is a condition affecting edentulous patients, significantly impacting their lifestyle. It is now understood that the full spectrum of characteristics initially described by Kelly is not always essential for the identification of syndrome.Our main objective was to determine the prevalence of Combination Syndrome among patients who attended the dental clinics of a Dentistry School of an Ecuadorian university between 2017 and 2019. We also aimed to investigate its association with potential factors such as type of edentulism, age, and sex.This observational, and retrospective study analyzed 651 panoramic radiographs; 404 belonged to women and 247 to men. Radiographic signs of the syndrome, including premaxilla bone resorption, maxillary tuberosity enlargement, and posterior mandibular bone resorption, were evaluated. The study sought to ascertain the prevalence of syndrome, providing statistical data to highlight the importance of care for these patients.Our findings indicate that 8.35% of all patients seen during the study period presented with the syndrome. Among these, a relationship with mandibular Class I edentulism was demonstrated. According to the Tolstunov Classification, Class I modification I was found to be associated with age but not with sex. Regarding age, older adults constitute a high-risk group.We concluded that Combination Syndrome is strongly associated with mandibular Class I edentulism. Age is a key contributing factor, with a notably high prevalence observed in older adult patients.

Introduction: Dentoalveolar trauma, in maxillary incisors, is common and can result in complicated fractures with pulp exposure. Adhesive reinsertion of the coronal fragment and vital pulp therapy (VPT) can be effective conservative strategies to maintain the vitality and integrity of the tooth. Materials and Methods: 13-year-old adolescent with a complicated coronal fracture. After clinical and radiographic examination, using pulp sensitivity tests, confirming the possibility of conservative treatment. A partial pulpotomy was performed applying Biodentin for pulp protection and repair. Tooth preparation included the use of adhesive systems and composite resin. The adhesive connection of the fragment was performed with thermomodified resin, followed by layering to complete the dental anatomy, following polymerization, finishing and polishing protocols. Results: With the protocol carried out, an esthetically satisfactory and functional restoration was obtained without postoperative complications. The conservative technique allowed protection of the remaining tooth structure and restoration of the optical properties, proving to be effective in coronal fractures.Conclusions: The combination of VPT and adhesive reinsertion of the tooth fragment is a viable strategy for treating complicated coronal fractures with pulp exposure. This conservative approach offers stable and durable clinical results, highlighting the importance of selecting appropriate materials and following strict protocols for successful treatment. The aim of the present study is to report the clinical case of a complicated coronal fracture with pulp exposure, approached in a minimally invasive approach and using conservative protocols.    

The relationship between the presence of oral lesions in type II diabetic patients and the use of dental prostheses, with the focus on how these lesions affect quality of life and are compared with non-diabetic patients. Research reveals that diabetic patients who wear dentures face a higher prevalence and severity of oral lesions, such as ulcers and candidiasis, due to factors such as poor glycemic control and xerostomia. These conditions not only aggravate the onset of oral problems, but also have a significant negative impact on your quality of life. Comparative analysis shows that, compared to non-diabetic patients, diabetics have a higher frequency of infections and a greater impact on general health, exacerbating systemic complications and decreasing general well-being. In this sense, the main objective of the present bibliographic review was to determine the relationship between type II diabetes mellitus, the use of dental prostheses and the presence of oral lesions in adult patients. The literature analyzed highlighted the urgent need for specific preventive and corrective strategies for diabetic patients who use dental prostheses, in order to improve their oral health and quality of life. They conclude in the improvement of glycemic control, the rigorous implementation of oral hygiene, and more frequent monitoring for the effective management of oral lesions.
