Section of Dental-Oral Maxillofacial Surgery

In the current era of expedited orthodontics, among many clinicians, tertiary care hospitals and patients, surgery first orthognathic approach (SFOA) has gained popularity.

In SFOA, the absence of a presurgical phase allows surgery to be performed first, followed by comprehensive orthodontic treatment to achieve the desired occlusion. The basic concepts of surgery early, surgery last, SFOA and Sendai SFOA technique along with its variations are reviewed in the present article. The recent advancement in SFOA in the context of preoperative …

Evaluation Of Micro Leakage Of Root Canals Filled With Different Obturation Techniques: An In Vitro Study, Maham Muneeb Lone, Farhan Raza Khan

Section of Dental-Oral Maxillofacial Surgery

Background: Despite a plethora of studies done comparing different obturation techniques using gutta-percha, there is no consensus as to which obturation technique results in a 'better' sealing of root canal space. Aims of the study are to compare mean apical micro leakage in root canals of extracted teeth obturated with cold laterally compacted gutta-percha and thermoplasticised injectable gutta-percha using calcium hydroxide based sealer.

Methods: It was an in-vitro experimental study carried out using extracted teeth. After access cavity preparation and canal preparation in 70 teeth, they were randomly divided into 2 groups and filled with two different obturation …
