ABSTRACT
OBJECTIVE: The objective of the study is to determine the oral health knowledge, attitude, and practices among the health-care workers (HCWs). MATERIALS AND METHODS: The present questionnaire-based survey among 473 HCW comprising of doctors, nurses, pharmacists, technicians, and interns was carried out to know the oral health knowledge, attitude, and practices among different HCW. Responses were recorded and data were assessed through descriptive statistics and by applying analysis of variance, Chi-square, and z-tests. RESULTS: Maximum of doctors (98.7%), nurses (80.4%), interns (73.3%), pharmacists (70.8%), and technicians (67.1%) responded correctly that oral health is related to systemic health followed by treating a decayed tooth is equally important as treating other body ailments. Doctors revealed higher mean knowledge scores in comparison with other HCW. A significant difference is noted with regard to frequency of dental visit (P = 0.000), reason behind dental visit (P = 0.001), and barrier for not visiting the dentist (P = 0.013) among males and females. Similarly, a significant difference is noted with regard to frequency of dental visit (P = 0.001), dentist familiarizing about the treatment (P = 0.001), and his concern about the patients (P = 0.001) among between different HCW. CONCLUSION: From the results of the present study, a variation in oral health knowledge was observed among different HCW. All the participants showed a positive attitude toward professional dental care.
ABSTRACT
AIM: The aim of the present study was to compare the canal transportation and centering ability of three rotary nickel-titanium (NiTi) systems (Twisted Files [TF], HyFlex controlled memory [CM], and Wave One [WO]) in curved root canals using computed tomography (CT). MATERIALS AND METHODS: Sixty freshly extracted single-rooted teeth having curved root canals with at least 25-35 degrees of curvature were selected. The teeth were randomly divided into three experimental groups of twenty each. After preparation with TF, HyFlex CM, and WO, all teeth were scanned using CT to determine the root canal shape. Pre- and post-instrumentation images were obtained at three levels, 3 mm apical, 9 mm middle, and 15 mm coronal above the apical foramen were compared using CT software. Amount of transportation and centering ability were assessed. The three groups were statistically compared with analysis of variance and post hoc Tukey's honestly significant difference test. RESULTS: Least apical transportation and higher centering ability were seen in HyFlex CM file system in all the three sections followed by TF. WO file system showed maximum transportation. CONCLUSIONS: The canal preparation with HyFlex CM file system showed lesser transportation and better centering ability than TF, WO file system.
