Unilateral Comminuted And Complicated Fracture Of The Mandible Due To Dog Attack, W.C. Ngeow, C. B. Lian Jul 1996

Unilateral Comminuted And Complicated Fracture Of The Mandible Due To Dog Attack, W.C. Ngeow, C. B. Lian

Wei Cheong Ngeow

Fractures of the mandible and their management are discussed in detail in textbooks and articles dealing with facial trauma. This paper presents the management and treatment of a case of a unilateral comminuted and complicated fracture of the mandible due to dog attack on a geriatric patient. The attack also severed the patient's right arm. Due to the severity of the trauma, an emergency surgery was performed on the mandible and arm.


The Effect Of Guidor™ And Hop-1 On Hard Tissue Healing : Following Periradicular Surgery In Cats, Hugh Maguire Jun 1996

The Effect Of Guidor™ And Hop-1 On Hard Tissue Healing : Following Periradicular Surgery In Cats, Hugh Maguire

Loma Linda University Electronic Theses, Dissertations & Projects

The purpose of this study was to evaluate the effects of the resorbable membrane Guidor™ and the osteogenic protein hOP-1 on hard tissue healing following periradicular surgery in cats.

Surgical endodontic therapy was performed on the maxillary canine teeth of twelve cats. After orthograde root canal therapy, flap reflection, osteotomy, resection of the root end, root end cavity preparation and the placement of a root end filling, eight of the surgical sites were treated with Guidor™ and eight with hOP-1. The remaining eight sites received no further treatment and served as controls.

The animals were sacrificed at twelve weeks following …

An unusual case of a second maxillary molar with a dilacerated root visible clinically is described. Apicectomy followed by retrograde amalgam filling was performed whereby gingival coverage and gingival seal was achieved.


The Ball Mill As A Means Of Investigating The Mechanical Failure Of Dental Materials, Noor Hayaty Abu Kasim Abu Kasim N.H. Dec 1995

The Ball Mill As A Means Of Investigating The Mechanical Failure Of Dental Materials, Noor Hayaty Abu Kasim Abu Kasim N.H.

Noor Hayaty Abu Kasim Abu Kasim N.H.

Objective: The main purpose of this paper is to present a new method of predicting clinical performance using mechanical loading in a ball mill. Methods: A series of four experiments (two involving a hybrid composite and one each on orthodontic brackets and bands) is described in which the ball mill was used to subject specimens to mechanical fatigue. Results: A reproducibility study using composite beam specimens showed no significant difference between the Mean Survival Time (MST) in all the three experimental runs (P = 0.42). When subjected to thermal cycling, the MST of the cycled group was 155.0 min compared …
