RESUMO

OBJECTIVES@#The purpose of this study was to determine the incidence of radix molaris (RM) (entomolaris and paramolaris) in the mandibular first permanent molars of a sample Saudi Arabian subpopulation using cone-beam computed tomography (CBCT).@*MATERIALS AND METHODS@#A total of 884 CBCT images of 427 male and 457 female Saudi citizens (age 16 to 70 years) were collected from the radiology department archives of 4 dental centers. A total of 450 CBCT images of 741 mature mandibular first molars that met the inclusion criteria were reviewed. The images were viewed at high resolution by 3 examiners and were analyzed with Planmeca Romexis software (version 5.2).@*RESULTS@#Thirty-three (4.5%) mandibular first permanent molars had RM, mostly on the distal side. The incidence of radix entomolaris (EM) was 4.3%, while that of radix paramolaris was 0.3%. The RM roots had one canal and occurred more unilaterally. No significant difference in root configuration was found between males and females (p > 0.05). Types I and III EM root canal configurations were most common, while type B was the only RP configuration observed.@*CONCLUSIONS@#The incidence of RM in the mandibular first molars of this Saudi subpopulation was 4.5%. Identification of the supernumerary root can avoid missing the canal associated with the root during root canal treatment.

RESUMO

The main objective of this study was to assess the level of awareness as well as satisfaction regarding dental insurance coverage among employees working in different companies in Riyadh, Kingdom of Saudi Arabia. The survey questionnaires were distributed among 800 employees with health insurance coverage. Chi-square tests were used to analyze significant association between age, gender, Nationality, marital status, level of education, and monthly income with awareness related questions. The association between the socio-demographic variables and the satisfaction criteria were analyzed using Kruskal Wallis and the Mann-Whitney tests. Six hundred and seventy five employees responded to the questionnaire with a response rate of about 84%. Graduates, married and males respondents demonstrated better awareness about their dental insurance. Age and monthly income were also positively related to the level of awareness. Low income groups were least satisfied with the dental insurance policy. Although great majority of the respondents in this study had dental insurance coverage, the level of awareness varied between different socio-demographic subgroups
