AI Article Synopsis

  • The study aimed to examine how tamoxifen affects tooth loss in women who have survived breast cancer, using a sample of 140 participants and assessing various sociodemographic and dental factors.
  • Results indicated that breast cancer survivors on tamoxifen for over a year experienced significantly increased tooth loss, with a mean of 12.96 missing teeth, and factors like age and dental care usage also contributed to this issue.
  • The conclusion highlighted that prolonged tamoxifen use correlates with greater tooth loss, suggesting a need for enhanced oral health care strategies for breast cancer survivors undergoing this treatment.

Article Abstract

Objectives: Investigate the effect of tamoxifen on the occurrence of tooth loss (TL) in breast cancer (BC) survivors.

Methods: A cross-sectional study was conducted with 140 BC survivors using tamoxifen therapy. Sociodemographic, medical, and dental data were evaluated. TL was determined using the M component of the Decayed, Missing and Filled Teeth (DMFT) index. Logistic regression models were run to determine associations between the independent variables and outcome (TL).

Results: Mean TL was 12.96 (SD 8.88). Only three participants had lost no teeth and 10.7% were completely edentulous. Participants who used tamoxifen for more than 1 year had a higher mean missing teeth (13.99 vs. 10.45; P = 0.030). After the adjustments, the occurrence of more than 12 missing teeth was 2.75-fold higher among women who used tamoxifen for more than 1 year (95% CI: 1.06-7.12). Moreover, age over 65 years, referral for treatment by the public healthcare system, less use of dental services, xerostomia, and a lower occurrence of dental caries remained associated with the loss of more than 12 teeth.

Conclusion: Longer use of tamoxifen was associated with greater tooth loss in breast cancer survivors.

Clinical Relevance: Based on estimates of the increase in cases of breast cancer, the prolonged use of tamoxifen for the treatment of this disease can exert an impact on oral health through the occurrence of tooth loss. These findings can contribute to the planning and implementation of oral health care and prevention strategies for such patients.

Dental maxillary sinus pathology: a CBCT-based case-control study.

Odontology

January 2025

Division of Oral Radiology, Faculdade São Leopoldo Mandic, Rua Dr. José Rocha Junqueira 13 Campinas, São Paulo, 13045-755, Brazil.

This study evaluated the association between dental infection and maxillary sinus pathology, and the influence of age, sex, type of tooth, root proximity to the sinus floor, the condition of the primary maxillary ostium, and the presence of an accessory maxillary ostium in this process. Computed Tomography scans were selected, and upper posterior teeth were evaluated for the presence of apical periodontitis (AP), bone loss with furcation involvement, and endoperiodontal lesion (EPL), subsequently, sinuses were evaluated for mucosal thickening (MT) and opacification of the maxillary sinus (OMS). Logistic regression models were constructed, and Chi-squared and Fisher's tests were applied.

Periodontitis, a common chronic inflammatory condition caused by bacteria, leads to loss of attachment, resorption of alveolar bone, and ultimately tooth loss. Therefore, reducing bacterial load and fostering alveolar bone regeneration are essential components in the treatment of periodontitis. In this study, we prepared smaller-sized Ag-Metal Organic Frameworks (Ag@MOF) and loaded with sodium alginate (Alg) hydrogel for periodontitis treatment.

Objectives:  In the context of military health, removable partial acrylic dentures (RPADs) are crucial for the quality of life and performance of Indonesian National Armed Forces (TNI) soldiers. Given the demanding and unpredictable military environment, RPADs provide a solution for soldiers experiencing tooth loss. This research aims to identify behavioral factors influencing the lifespan of RPADs among TNI soldiers.

Objective:  According to the evidence, the level of glycemic control is of key importance in determining the increased risk of periodontal disease (PD). The aim of the study was to evaluate the role of metabolic control as a key factor leading to the development and severity of periodontitis and compare the periodontal and oral hygiene status with the glycated hemoglobin levels.

Materials And Methods:  The evaluation was undertaken with diabetic patients (59 uncontrolled diabetics and 36 controlled diabetics) from a patient cohort of the Hospitalar Center of Tâmega e Sousa and subjects without diabetes ( = 95).
