Background: Palatal surgeries are associated with many complications. Accessory foramina may be a cause of concern. The aim of the present study was to assess the occurrence and to evaluate the anatomical features of accessory palatine foramina and their bony canals using cone beam computed tomography (CBCT). Materials and methods: The incidence, location, and types of foramina on the palate were evaluated in 170 CBCT scans. Readings from coronal, sagittal, and axial planes were recorded using Planmeca Romexis Viewer 5.4.1.R. computer program. Data were tabulated and evaluated. Results: Other than nasopalatine, greater and lesser palatine foramina, 278 foramina were observed in the palatal surface of the upper jaw in different locations. New accessory palatine foramina were found posteriorly in 14.71% of the studied scans with wide anatomical variations. Unusual foraminal canals were seen crossing the floor of the maxillary sinus laterally. The incidence of the anterior accessory palatine foramina was 73.53%. Bilateral accessory palatine foramina were found in 43.53% of cases. Conclusions: Accessory palatine foramina and their bony canals are frequently seen in CBCT with wide anatomical variations. New unusual connecting canals are found passing from palatine foramina to the lateral wall of the maxillary sinus through the sinus floor. These findings should be considered when planning for anesthesia and surgery in the palate.
Objective: This study was conducted to evaluate the biocompatibility of two bioactive materials, Cention N (CN) and ACTIVA bioactive, then compare the result with that of Mineral Trioxide Aggregate (MTA) as a retrograde filling materials.Methods: Sixty Albino male rats were used in the study, four polyethylene tubes were subcutaneously implanted into the rats, an empty one was used as a control group, and the other three tubes were filled with ACTIVA, Cention N and MTA-HP. Rats were then divided into three groups (n = 20 rats) following the sacrification time into three intervals: one, two and three weeks, then, the tissue specimens were analyzed histopathologically. The collected data were subjected to statistical analysis.Results: ANOVA test showed that the lowest inflammatory reaction was recorded for ACTIVA while a high degree of chronic inflammation was recorded for MTA group, with highly significant differences, P< 0.001. ACTIVA bioactive material exhibited observable decline of inflammation and fibrosis in a comparison to the control.
Conclusions:The two bioactive materials showed a higher biocompatibility comparable to MTA. ACTIVA showed the highest degree of biocompatibility related to the decreased intensity of inflammation, with well-formed fibrous connective tissue conversion and improved healing patterns.
Background: One of the challenges that face effective dental and oral surgical treatment is reducing transmission of infectious diseases. This study assessed the challenges and the changes in management of patients in private dental clinics in Egypt in view of rapid spread of SARS-COVID-19.Methods: Six private dental clinics in Egypt were enrolled in this study. Changes in the management protocols were recorded and evaluated. Data were collected about the changes in clinic policies and in infection control practices. The modifications in patient management and the number and types of treatment approaches either surgical or non-surgical for dental and oral conditions were recorded and evaluated.Results: The most commonly followed guidelines were wearing gloves followed by wearing masks and using disposable products. Remote consultations and shortage of personal protective equipment were recorded by all clinics. Management approaches included conservative endodontic management for periapical lesions and fistulae. Aerosols and minor surgical interventions could not be avoided in many cases.
Conclusion:Conservative approaches were effective and could be considered during pandemic spread. Dental personnel should be more aware and more prepared for any pandemic spread. Management modifications and strict precautions should be followed.
