Inculcating research curriculum in Operative Dentistry - Endodontics residency programme: Experience and outcomes.

Incorporating research education and training in residency curriculum increases the understanding of evidence-based decision-making among doctors in training. Evidence suggests that the addition of research is linearly associated with improvement in clinical competence, and encourages the residents to shape their career as clinical investigators. The current paper was planned to share the experience of adding research into the core curriculum of Operative Dentistry-Endodontics residency programme at a tertiary care university hospital, and to evaluate the outcome achieved with that change.

Remaining dentine thickness of root canals prepared with K-3 and ProTaper rotary systems.

Objective: To compare the remaining dentine thickness of root canals prepared with K-3 and ProTaper files..

Methods: This in-vitro experimental study was conducted from 1st April-30th September 2015 at the dental clinics of Aga Khan University Hospital, Karachi, and comprised human teeth.

Practice Of Endodontic Re-Treatment In Four Cities Of Pakistan.

Background: Root canal re-treatment is the procedure of choice when the primary root treatment fails but patient is inclined toward salvage of the tooth. The re-treatment is often a challenging procedure owing to lack to the predictability in the outcomes. Since, there is a no single way of planning and executing such procedure, a study was planned to assess the knowledge, attitude and practice regarding endodontic re-treatment among Pakistani dentists.

Comparison of fracture and deformation in the rotary endodontic instruments: Protaper versus K-3 system.

This experimental study was done on extracted human teeth to compare the fracture and deformation of the two rotary endodontic files system namely K-3 and Protapers. It was conducted at the dental clinics of the Aga Khan University Hospital, Karachi, A log of file deformation or fracture during root canal preparation was kept. The location of fracture was noted along with the identity of the canal in which fracture took place.

Mandibular first molar with six root canals: a rare entity.

Recently, there has been an ongoing trend of case reports that highlight the presence of more than four root canals in mandibular first molars. This tendency warns clinicians to be more prudent when dealing with mandibular first molars requiring endodontic treatment. Moreover, radiographic examination should be taken as a clue providing tool rather than as an absolute guide to anatomy and its associated aberrances.

The need of paediatric dentistry specialists in Pakistan.

In the last decade, a rapid increase has been observed in the number of dentists due to establishment of a number of dental colleges in Pakistan. Very few of these institutions have Paediatric Dentistry Department. Similarly, no postgraduate Paediatric Dentistry training program exists in the two major provinces of the country.

ProTaper rotary instrument fracture during root canal preparation: a comparison between rotary and hybrid techniques.

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.

Assessment of convergence angle of full-coverage porcelain fused to metal crowns in clinical practice.

Background: Full-coverage porcelain fused to metal crowns is commonly recommended for restoration of extensively damaged teeth. Ability of the dentist to adequately prepare teeth is fundamental to success and longevity of these restorations.

Aims: This study was designed to compare recommended convergence angle and taper values of tooth preparation with clinically practiced values and to assess the factors such as tooth position, operator experience, vitality, and restorative status on convergence angle of prepared teeth.

Comparison of convergence angle of prepared teeth for full veneer metal ceramic crowns.

Objective: To compare clinically practiced convergence angle values of tooth preparation with recommended values, and also the effect of tooth position and operator experience on convergence angle.

Study Design: Analytical study.

Place And Duration Of Study: The study was carried out at the Dental clinic, The Aga Khan University Hospital, Karachi, from January to June 2007.

Frequency and distribution of endodontically treated teeth.

Objective: To determine the distribution and pattern of carious teeth involvement in permanent teeth requiring endodontic treatment.

Study Design: Cross-sectional study.

Place And Duration Of Study: Dental Section of The Aga Khan University Hospital, Karachi, from September 2004 to March 2005.

Factors associated with Non-Carious Cervical Lesions (NCCLs) in teeth.

Objective: To determine factors associated with Non-Carious Cervical Lesions (NCCLs) and the teeth most commonly involved in such lesions.

Study Design: Cross-sectional study.

Place And Duration Of Study: Department of Operative Dentistry, Section of Dentistry at Aga Khan University Hospital, Karachi, Pakistan, from December 2005 to January 2006.
