- Epidemiological Study on Oral Cancer in the Dominican Population (2018-2024)(2025) María L. Socías Pappaterra; Austria I. Mendoza Serret; Helen J. Rivera Estaba; Adolfo Arthur. IADR - International Association for Dental ResearchObjectives: To identify epidemiological data on Oral Cancer (OC) in a population from Dominican Republic from 2018 to 2024. Methods: This cross sectional, retrospective and descriptive study was based on a database from the Dominican Institute of Dermatology and Skin Surgery “Dr. Huberto Bogaert”. Approval was obtained from the Iberoamerican University Ethical Committee. Twenty cases were selected according to gender, age group, anatomical location, clinical presumptive diagnosis, histological type, and degree of differentiation. Results: 20 cases representing OC were selected. Eleven (55.0%) were female and 9 (45.0%) male. Sixteen patients (80.0%) were older than 60 years, the rest were between 41 and 60 years, and 0 to 40 years. The most frequent anatomical site was the lower lip, observed in 7/20 cases (28.0%), of these 2 were females (8.0%) and 5 males (20.0%). The second most common site was the lateral border of the tongue in 6 patients (24.0%), 5 females (20.0%) and 1 male (4.0%). Squamous cell carcinoma (SCC) was diagnosed in 18 patients. Histological grading showed 10 cases as well-differentiated SCC (38.5%), 4 females (15.4%) and 6 males (23.1%); 6 cases represented moderately differentiated SCC (23.1%), 5 female (19.2%) and 1 male (3.9%) respectively; and 2 female cases revealed superficially invasive SCC (7.7%). Conclusions: The frequency of OC was found to be higher in females and predominantly on the lower lip. This study underscores the importance of exploring risk factors, genetic and environmental, that may contribute to the incidence of OC in the studied population and highlights the need for implementing preventive programs based on early detection.
Conferencia (póster) - Efficacy of Curcuma Longa (Zingiberaceae) Against Parvimonas Micra. in Vitro Study(2025) Ana María Carpio; Fabio Camacho-Alonso; Massimo Corigliano. IADR - International Association for Dental ResearchObjectives: To determine the antibacterial efficacy of Curcuma extracts at different concentrations with an in vitro periodontal strain: Parvimonas micra. Methods: An exploratory, analytical, and longitudinal experimental study was designed. Different types of extracts (ethanolic, methanolic and aqueous) were prepared from Curcuma from India and Curcuma grown in the Dominican Republic. Curcuma solutions were prepared at different concentrations (100, 50, 25, 12.50, 6.25, 3.125, 1.562, 0.780, 0.390, 0.195 mg/ml) from each one. To evaluate the antibacterial efficacy of Curcuma, modified disk diffusion method was performed. The effectiveness of Curcuma extracts was determined by measuring the efficacy of halo in mm. Results: It was observed that Curcuma extracts had efficacy against Parvimonas micra at a minimum concentration of 50 mg/ml in the (ethanolic and methanolic) and at 100 mg/ml in the (aqueous), with an average efficacy halo of 7mm. Conclusions: Extracts from Curcuma from India and Dominican Republic have antibacterial efficacy against Parvimonas micra at a minimum concentration of 50mg/ml. The efficacy average of both Dominican and Indian Curcuma were equal (p value=1,00>0,05) showing efficacy within the three extracts. This understudied periodontopathogen has been recently associated as a keynote in the dysbiotic pathway of periodontal disease and colon cancer and further studies are recommended.
