ABSTRACT

Objective:

The aim was to investigate the accuracy of linear measurements of the mandibular ridge recorded using two CBCT systems. Material and

Methods:

Eleven human dry skull were used in which mandibles were chosen to measure width and height in 6 sites. Before scanning, the points were marked using barium sulfate radiopaque contrast media. Mandible imaging was done using two systems Newtom3G and Cranex3D. Alveolar ridge dimensions were recorded by two observers under uniform condition using special software for each system. The measurement errors and inter-examiner reliability were calculated for each modality and compared with each other and analyzed via SPSS software version 18. The level of significance was set at P < 0.05.

Results:

The overall mean was 0.08 mm for Cranex system and 0.5 for Newtom system. The mean of two systems had no statistically significant difference in comparison with each other or with the gold standard. The statistical analysis showed high inter-observer reliability (P < 0.05).

Conclusion:

CBCT is highly accurate and reproducible in linear measurements in the different areas of the maxillofacial region.
RESUMO

Objetivo:

O objetivo deste estudo foi investigar a acurácia de medidas lineares do rebordo mandibular utilizando dois sistemas de TCFC. Material e

Métodos:

Onze crânios secos humanos foram utilizadas e seis regiões das mandíbulas foram escolhidos para mensuração da largura e da altura. Antes da digitalização, os pontos foram marcados com contraste radiopaco de sulfato de bário. Imagens da mandíbula foram realizadas usando dois sistemas Newtom3G e Cranex3D . As dimensões rebordo alveolar foram determinadas por dois observadores em condições uniformes utilizando software específico para cada sistema. Os erros de medição e confiabilidade interexaminadores foram calculados para cada modalidade, utilizando o software SPSS versão 18, e comparados entre si. O nível de significância adotado foi p < 0,05.

Resultados:

A média geral para o sistema Cranexfoi de 0,08 mm e 0,5 para o sistema de Newton. As médias dos dois sistemas não apresentaram diferença estatisticamente significativa em comparação entre si ou com o padrão-ouro. A análise estatística mostrou alta confiabilidade interexaminador (p < 0,05).

Conclusão:

TCFC é altamente precisa e reprodutível em medidas lineares nas diferentes áreas da região maxilofacial.
