Résumé
This study was conducted to evaluate oral hygiene instructions given to orthodontic patients by general dental practitioners of Sindh. Questionnaire proforma were given to 120 general dental practitioners [GDPs] who are doing independent clinical practice in Hyderabad and Karachi regions. Data were analyzed by using Statistical package for social sciences [SPSS-16.0]. The results of this study showed that 45.8% GDPs prescribed specific orthodontic brush, 27.5% ordinary manual tooth brush and 10% power [electrical] brush for plaque removal. 60% advised brushing in the morning, evening and at night. For inter-dental cleaning 22.5% advised interdental brush and 19.2% dental floss. 52.5% also occasionally prescribed mouth wash as an adjunct for maintaining good oral hygiene. According to the results of this study it could be stated that every GDP in Hyderabad and Karachi was giving oral hygiene instructions to orthodontic patients after placement of orthodontic appliance. Practitioners who have more clinical experience were better in giving oral hygiene instructions, but still they need more information and awareness to enable them to properly instruct the orthodontic patients
Résumé
Ceramic brackets were brought into orthodontics in an attempt to meet the rising requirement for added esthetic appliances. The objectives of this study were to assess and compare the shear bond strength and bond failure location of presently available clarity ceramic and Transcend brackets. This comparative study was conducted at Department of Orthodontics, de'Montmorency College of Dentistry Lahore and PCSIR, Lahore for one year from 10[th] June 2003 to 9[th] June 2004. Sixty brackets of each type were bonded to 120 extracted human 1[st] premolar teeth with the similar bonding system. Each bracket type was tested on a Schimadzu testing machine to find out the shear force levels necessary to debond these brackets. All the teeth were examined under an optical and stereo microscope to evaluate the Adhesive Remnant Index [ARI] at bond failure inter phase. The independent t-test performed for comparing the clarity and transcend 6000 ceramic brackets, indicated that there were no statistically significant difference between two brackets tested [P=0.256]. The Result of ARI scores indicated that there were no significant differences between the two brackets. [P=0.312]. Shear bond strength and ARI scores between the Clarity and Transcend 6000 ceramic brackets are insignificant
