ABSTRACT
Medical emergency when occurs in a dental environment should be handled efficiently and effectively in order to sustain life until medical help arrives. This study aimed to enhance knowledge amongst dental practitioners about the possible risks of a medical emergency to improve patient care. A questionnaire based study was conducted in the dental teaching hospitals of the twin cities, Rawalpindi and Islamabad in 2015. The questionnaire comprised of three sections to assess dentists' perception and dentists' knowledge on the commonly faced medical emergencies along with dentists' confidence in performing Basic Life Support [BLS]. 215 questionnaires were distributed out of which 192 were returned. The study sample included 122 female and 70 male dentists with a minimum clinical experience of one year. The results showed 71.4% received a formal BLS training while 84.4% wanted to receive thetraining. Moreover, the mean medical emergency score obtained was 5.28 out of a maximum of 10. 55.2% of the dental practitioners felt confident in performing Cardio Pulmonary Resuscitation [CPR], out of which, 80.5% had the correct knowledge of performing a CPR according to this study. The most significant finding was almost half of the dentists lack the knowledge and necessary training. Hence, in order to improve quality of patient care annual BLS courses should be made mandatory
ABSTRACT
A key aspect of orthodontic diagnosis and treatment planning is soft tissue evaluation, which includes the assessment of soft tissue-profile esthetics. Inherent facial features as well as extrinsic factors such as hair style, complexion, and makeup have a strong influence on aesthetics, biasing the judgment of profile esthetics. Therefore, investigators have used profile line drawings and profile silhouettes to eliminate the effects of other facial features while studying profile. The aim of the study was to determine the agreement regarding the most preferred facial profile among patients and orthodontists. This study was carried out at the outpatient department at Islamic International Dental Hospital from August 2011 to February 2012. A balanced facial profile with class I cephalometric norms was modified with the help of a computer software Viewbox[trade mark sign] 4.0 Software [DHAL Orthodontic Software, Athens, Greece] to generate 7 profiles with variation in maxilla and mandible. Silhouettes of these 7 profiles were ranked by patients and orthodontists [n=80each]. A scale of 1-7 was used with 1 being least attractive and 7 being most attractive. The normal profile [Profile C] was ranked the most attractive and the profile with retrusive mandible the least attractive. Significant difference was found in the agreement of ranking of the most preferred facial profile by the patients and orthodontist [p-value0.001]. Normal [balanced] facial profile was ranked to be the most preferred facial profile by both patients and orthodontists
ABSTRACT
Orthodontics has undergone a paradigm shift with a focus of treatment on facial aesthetics. Buccal corridor show has always remained a controversial aspect of smile aesthetics. As orthodontists often expand the arches as a mean of gaining space, it is of interest to know how the amount of tooth display affects smile attractiveness. The objectives of this study were to compare the difference in perception of orthodontists and laypersons to altered smile aesthetics, specifically with regards to buccal corridor show. This was a cross sectional study carried out in the OPD of Islamic International Dental Hospital, Islamabad from September 2011 to March 2012. A frontal smiling photograph was obtained from a non-orthodontic female patient with a pleasing smile. Using computer software Adobe Photoshop 7.0 [San Jose, Calif], the smile was digitally altered to create different variations of the normal buccal corridor space. For the main survey the photographs were projected as a power point presentation to orthodontists and laypersons [n =46]. The raters were asked to score the overall appearance of the photographs using visual analogue scale from 1 to 10. There was no significant difference in the perception between orthodontists and laypersons for variations in buccal corridor [p < 0.05]. Both groups preferred smiles with minimal buccal corridors. Laypersons and orthodontists preferred smiles with absent or minimal buccal corridors. There is no gender or age group difference in buccal corridors [BC] attractiveness
ABSTRACT
The most common procedure followed globally for the bony repair of a cleft palate is by grafting the iliac crest in the defect. The objective of this study was to evaluate the success of the alveolar bone grafting procedures carried out at our institute by using the Berglands Index. A total of 12 patients were evaluated by taking periapical radiographs of the grafted site 6 months post surgery. It was found that 77% of the patients had a bone level of more than 3/4. It was also deduced that the success rate of the grafted bone was 100% when the bone was grafted before the eruption of the canine while success rate dropped to 40% in patients in which the procedure was performed after the eruption of the canine

The aim of this study was to examine the applicability of simple equations proposed by Melgaco to predict the mesiodistal widths of the unerupted mandibular permanent canines and premolars in patients visiting Islamic International Dental hospital, Islamabad. This study was conducted during 2007-2008 at orthodontic department of Islamic International Dental Hospital, Islamabad. The sample consisted of 200 dental casts [100 male 100 female], obtained from patients reporting at the department of orthodontic, Islamic International Dental Hospital Islamabad, with the age range between 13 to 21 years. Mesiodistal tooth widths were measured with a digital vernier caliper. Correlation and determination coefficients were found between Sum of mandibular Incisors and first Molars [SMI] and Sum of actual width of mandibular Canine and Premolars [SCPM] of mandibular arch. A paired Student t test was used to compare the predicted and actual sum of the mandibular permanent Canines and Premolars [SCPM] for both genders combined and separately. Correlation coefficient was 0.673 and determination coefficient was 0.452 between SMI and actual SCPM. Significant difference was found between predicted and actual values of SCPM for male [0009] and for both genders combined [0.000]. Female subjects showed no significant difference [0.010].Only the simple equation proposed for female subjects by Melgaco et al is applicable in our sample

Heliosit Orthodontic was developed to ease the bonding procedure of orthodontic attachments by eliminating the need for primer application both on the bracket base and the etched tooth surface. The aim of this study was to determine the shear bond strength of Heliosit Orthodontic and then compare it with the control group of Transbond XT. The study consisted of two groups A and B of 80 human premolar teeth each bonded with mesh based metal brackets. The bonding agent used in group A was Transbond XT and that of group B was Heliosit Orthodontic, Every effort was made to control the cofounding variables including light tip distance, force of application of bracket, storage of teeth before and after bonding and orientation of bracket in the acrylic block this was followed by debonding of the brackets by shearing in a universal testing machine. It was found that the mean shear bond strength of Transbond XT was 25.5 MPa and that of Heliosit orthodontic was 10.54 MPa. The t-test revealed that there was a significant difference between the shear bond strength of the two groups. In conclusion the bond strengths of both the composites tested were greater than the recommended values of Reynolds for the composites to be clinically useful. It is recommended that the bond strength and the viscosity of the Heliosit Orthodontic be increased for it to be clinically as efftctive as Transbond XT
