Post-Traumatic Apexogenesis Of Immature Non-Vital Permanent Incisors, Robia Ghafoor

Section of Dental-Oral Maxillofacial Surgery

Injury to an immature permanent tooth may result in cessation of dentin deposition and root maturation leaving an open root apex and thin dentinal walls that are prone to fracture. Endodontic treatment is often complicated and protracted with an uncertain prognosis frequently resulting in pre-mature tooth loss. There are several advantages of promoting apexogenesis in immature teeth with open apices. It encourages a longer and thicker root to develop thus decreasing the propensity of long term root fracture. This case report highlights the role of Hertwig root sheath and dental papilla in continued root formation of immature permanent tooth, even …

Microaesthetics Of The Smile: Extraction Vs. Non-Extraction, Sanam Tauheed, Attiya Shaikh, Mubassar Fida

Section of Dental-Oral Maxillofacial Surgery

OBJECTIVE: To compare microaesthetics in pre- and post-orthodontic cases, treated with non-extraction and extraction treatment and assessed whether the achieved microaesthetic parameters are comparable to the proposed norms.

STUDY DESIGN: Quasi-experimental study.

PLACE AND DURATION OF STUDY: Orthodontic Clinic, the Aga Khan University Hospital, Karachi, from January 2005 to December 2009.

METHODOLOGY: Orthodontic records of 31 cases treated with non-extraction therapy and 26 cases treated with extraction of upper first premolars were selected. Patients were of Pakistani origin, aged between 12 to 30 years. Microaesthetics was assessed by measuring maxillary central incisor crown width-height ratio, connectors between the maxillary anterior …
