Accuracy of linear measurements performed with two imaging software in cone-beam computed tomography scans of dry human mandibles

ABSTRACT The present study aimed to assess the accuracy of linear measurements performed with two software packages in multislice (MSCT) and cone beam (CBCT) computed tomography (CT) images. The sample consisted of 10 human mandibles marked standardly 8 times with metallic orthodontic wires. The mandibles underwent both MSCT and CBCT scanning and were measured linearly and digitally with two software packages, namely Studio 3.1® (Anne Solutions®, SP, Brazil) (ST) and Implant Viewer 2.817® (Anne Solutions®, SP, Brazil) (IV). The linear measurements were the mandibular height (MH) and width (MW), and the distance from the alveolar ridge to the mandibular canal (AC). To validate the measurements, the mandibles were sectioned in the marked regions and measured with a digital caliper. Statistically significant differences were not observed between the measurements (MH, MW, and AC) taken digitally with the two software packages from images obtained from the two scanning modalities (MSCT and CBCT) and the measurements taken manually with a digital caliper (p>0.05). MSCT and CBCT images measured digitally with ST and IV software packages resulted in reliable outcomes when compared to measurements obtained manually. Both software and imaging modalities are reliably useful for planning surgical procedure in the dental practice.

Nível de conhecimento dos cirurgiões-dentistas sobre a qualidade dos prontuários odontológicos para fins de identificação humana / Level of knowledge of dentists on the quality of dental records for human identification

Objetivo: O objetivo desta pesquisa foi determinar por meio de questionário a 400 cirurgiões-dentistas cadastrados no Conselho Regional de Odontologia de Cuiabá-MT, o nível de conhecimento dos mesmos sobre a importância do prontuário nos processos de identificação humana. Resultados: Observou-se que 48,36% dos respondentes dispensam entre 10 e 20 minutos. Apenas 13,1% dos cirurgiões-dentistas pesquisados não têm o hábito de anotar as condições bucais antes de iniciar o tratamento e 42,62% fazem somente um odontograma. Dos 122 participantes, 11,11% informaram que a documentação não teve utilidade para estabelecer a identidade. Agravando o quadro, 33,6% dos respondentes afirmaram que não mantém os prontuários de pacientes atualizados. Conclusão: Concluiu-se que o cirurgião-dentista de Cuiabá-MT apresenta conhecimento satisfatório sobre elaboração, manutenção e importância do prontuário odontológico antes da morte no processo de identificação para o estabelecimento da identidade do paciente. Porém, nem sempre o preenche adequadamente, reduzindo assim o seu valor clínico, administrativo e legal.

Objective: The aim of this research was to determine the knowledge level of 400 dentists registered in the Regional Dental Council of Cuiabá, through a questionnaire about the importance of records in the process of human identification. Results: We observed that 48.36% of them dispense between 10 and 20 minutes. Only 13.1% of the surveyed dentists did not have the habit of writing down the oral conditions of their patients before starting treatment and 42.62% have only one odontogram filled. From the 122 participants, 11.11% reported that the documentation had no utility to establish the patients identity. To make the situation worse, 33.6% of them said they did not keep the records of patients updated. Conclusion: We conclude that the dentist of Cuiabá has enough knowledge on preparing, maintaining and importance of dental records before the death in the identification process for establishing the patient identity. But, always he did not properly fills the dental records, thus it has been reducing their clinical, administrative and legal value.
