RESUMO
Background: Dental imaging plays a crucial role in diagnosis and treatment planning, with cone-beam computed tomography (CBCT) and medical computed tomography (CT) being two common modalities. This study aims to compare the radiation doses associated with CBCT and medical CT imaging in dental applications to assess their relative safety and efficacy. Materials and Methods: We conducted a retrospective study using data from 100 patients who underwent both CBCT and medical CT scans for dental purposes. The radiation doses were measured in terms of dose-length product (DLP) for medical CT and dose-area product (DAP) for CBCT. The effective dose (ED) was calculated using appropriate conversion factors. Patient demographics, scan parameters, and radiation doses were recorded and analyzed. Results: The results indicated that the mean DLP for medical CT scans was 220 mGycm, whereas the mean DAP for CBCT scans was 150 mGycm². The corresponding mean effective doses for medical CT and CBCT were 2.5 mSv and 1.8 mSv, respectively. The radiation dose from CBCT was found to be approximately 28% lower than that from medical CT. Conclusion: This study demonstrates that CBCT imaging for dental applications results in significantly lower radiation doses compared to medical CT. While both modalities provide valuable diagnostic information, the choice of imaging technique should consider the balance between diagnostic quality and radiation exposure, especially for pediatric and high-risk patients. Dental practitioners should be aware of the potential dose reduction benefits associated with CBCT when appropriate for the clinical scenario.
RESUMO
BACKGROUND: A seafarer is a person who navigates waterborne vessels or assists as a crewmember in their operation and maintenance in all tough weather, but little research has been done to identify conditions that may lead to assess seafarer general health as well as oral health. AIM: To assess oral diseases including dental caries and periodontal conditions among seafarer's population arrived in Mundra Port, Kutch, Gujarat, India. MATERIALS AND METHODS: A descriptive cross-sectional survey was conducted to assess oral health condition of seafarer community of Mundra Taluka of Kutch District, Gujarat, India, from July 2014 to September 2014. RESULTS: Total of 385 subjects participated in the survey. Adverse habits show the overall 72.3% prevalence among the study population. Occurrence rate of caries, periodontal disease and prosthetic status were 88%, 75.1% and 6.5%, respectively. The best predictors for Decayed Missing Filled Teeth (DMFT), Community Periodontal Index (CPI) and prosthetic status were oral hygiene practices, adverse habit and educational status. CONCLUSIONS: Findings of the present study suggest that oral health condition of seafarer community was relatively poor, with high caries prevalence and poor periodontal health. This epidemiological survey has provided baseline information to underpin the implementation of oral health programmes.
