Knowledge And Awareness Regarding Uses Of Extracted Natural Tooth In Clinical Practice, Momina Anis Motiwala, Shizrah Jamal, Karshma Devi, Rabia Ghafoor

Section of Dental-Oral Maxillofacial Surgery

Restoration of aesthetics is one the major patients’ concern in dentistry which may be disrupted due to tooth-loss secondary to trauma, or as part of orthodontic treatment or periodontal problem. A number of treatment options are available for the replacement of teeth, but they may be expensive, and time-consuming, involving artificial teeth. For immediate tooth replacement, patient’s own intentionally extracted or unintentionally avulsed tooth maybe used. The current narrative review was planned to discuss various techniques for the use of natural tooth pontic, which preserves the original contours, size and colour of the replaced tooth. Before using these teeth in …

Objectives: To compare one year retention rate of bonded amalgam sealants (BAS) with that of conventional resin-based sealant (RBS).
Methods: It was a parallel group, equivalence, randomised controlled trial done during March 2018 to December 2019 at the dental clinics of Dow University of Health Sciences, and the Jinnah Sind Medical University, Karachi, Pakistan on children aged 12-16 years, who were randomly assigned to one of the two treatment groups (BAS vs. RBS). Complete retention of the sealant at one year follow-up was labeled as success. Multi-level mixed effect logistic regression model was employed. Study was registered at www.clinicaltrials.gov # …

Radiographic Evaluation Of The Margins Of Clinically Acceptable Metal-Ceramic Crowns, Sheikh Bilal Badar, Kamil Zafar, Rabia Ghafoor, Farhan Raza Khan

Section of Dental-Oral Maxillofacial Surgery

Objective: To radiographically evaluate the proximal marginal fit of the clinically acceptable metal-ceramic crowns.
Methods: The prospective study was conducted at the dental clinics of Aga Khan University, Karachi, from July to December 2018, and comprised metal-ceramic crowns that were evaluated prior to the cementation. Clinical examinations were conducted by seating the crown on the tooth preparation and visual assessment was done using sharp explorer along the margins. Clinically acceptable crowns were then evaluated on the bite-wing radiograph. Any horizontal or vertical inaccuracy of >0.5mm at the proximal margins was recorded as 'discrepancy'. Data was analysed using SPSS 22.
Results: …

Artificial Intelligence In Dentistry, Orthodontics And Orthognathic Surgery: A Literature Review, Tania Arshad Siddiqui, Rashna Hoshang Sukhia, Dinaz Ghandhi

Section of Dental-Oral Maxillofacial Surgery

Artificial intelligence is the ability of machines to work like humans. The concept initially began with the advent of mathematical models which gave calculated outputs based on inputs fed into the system. This was later modified with the introduction of various algorithms which can either give output based on overall data analysis or by selection of information within previous data. It is steadily becoming a favoured mode of treatment due to its efficiency and ability to manage complex conditions in all specialities. In dentistry, artificial intelligence has also popularised over the past few decades. They have been found useful for …

Are Pulp Sensibility Tests Still Sensible?, Huma Farid, Farhan Raza Khan, Lubna Pasha, Muhammad Saad Shinwari

Section of Dental-Oral Maxillofacial Surgery

Background:

Electric and thermal tests are the most commonly employed methods for the diagnosis of pulp health status. The objectives of our study are to assess the validity, yield and accuracy of cold and electric pulp tests in determining pulp vitality of teeth requiring endodontic treatment.

Methods:

A cross sectional study was carried out at the Dental Clinic of Aga Khan University Hospital on 75 patients requiring endodontic treatment. Before commencement of endodontic treatment, a provisional diagnosis of pulp status was made using an electric pulp tester and cold test. The tooth was then labelled as either vital or necrotic. …

Frequency Of Dentofacial Asymmetries: A Cross-Sectional Study On Orthodontic Patients, Nita Kumari Bhateja, Mubassar Fida, Attiya Shaikh

Section of Dental-Oral Maxillofacial Surgery

Background: Correction of orthodontic asymmetries is crucial to achieve functional occlusion, aesthetics and stability of post orthodontic treatment results. To date valid frequency data of dentofacial asymmetries in Pakistani orthodontic patients do not exist to document orthodontic treatment need. The objectives of this study were to determine frequency of dento-facial asymmetries, severity of dental asymmetries and to determine difference in frequency of dentofacial asymmetries in mixed and permanent dentition.
Methods: The sample of this cross-sectional study comprised of 280 patients (177 females and 103 males) with no history of previous orthodontic treatment having no craniofacial anomalies. Dento-facial asymmetries were assessed …

Protaper Rotary Instrument Fracture During Root Canal Preparation: A Comparison Between Rotary And Hybrid Techniques, Huma Farid, Farhan Raza Khan, Munawar Rahman

Section of Dental-Oral Maxillofacial Surgery

AIMS:

This study aimed to compare the frequency of ProTaper rotary instrument fracture with rotary (conventional) and hybrid (rotary and hand files) canal preparation techniques. Secondary objectives were to determine whether there was an association of ProTaper file fracture with the canal curvature and to compare the mean time required for canal preparation in the two techniques.

METHODS:

An in vitro experiment was conducted on 216 buccal canals of extracted maxillary and mandibular first molars. After creating an access cavity and a glide path for each canal, a periapical radiograph was taken and the canal curvature was measured with Schneider's …
