The oral and
maxillofacial trauma
Dr. HAMED H. AL-BARGI
Consultant in Oral and Maxillofacial Surgery, Dental OMFS Division, King
Fahad Armed Forces Hospital, Jeddah,
Saudi Arabia
The oral and maxillofacial trauma presents a unique
population in that both their injuries and the mechanisms of repair may have a
direct adverse effect on their ability to receive adequate nutrition.
Consequently, many can develop anemia, vitamin deficiencies and weight loss due
to fat and muscles wasting. Healthy, well developed and well nourished patient
generally have sufficient body stores to withstand surgical stress and
starvation for 7 to 10 days. The normal response to a traumatic injury is an
inflammatory reaction that usually peaks by the third day and abates by the
seventh to tenth day after injury. The metabolic response mobilizes amino acids
from lean tissue to support wound healing, immunologic response, and protein
synthesis. This hyper metabolism can lead to multiorgan failure if not
corrected or if complicated by further injury such as sepsis. The goal of early
intervention is to maintain host defenses and preserve lean body mass. An
accurate history of the traumatic incident is important in helping to arrive at
a final diagnosis. The type, intensity, duration, and direction of force can be
important clues in elucidating suspected areas of fracture in the oral and
maxillofacial region. The mechanisms of injury in the oral and maxillofacial
region are dominated by motor vehicular accident followed by altercation gun
shot wound and others.

Implant retained
auricular prostheses
Dr. WALID SADIG
Chairman, Department of Prosthetic Dental Sciences, College of Dentistry,
King Saud
University, Riyadh, Saudi Arabia
Prosthetic
replacement of missing ear can provide excellent cosmetic results.
Unfortunately, the absence of anatomic irregularities often results in
unfavorable adhesive retention of an auricular prosthesis. Alternatively, endosseous
implants specifically designed to be placed in the temporal bone permit
positive retention, easy orientation, prolonged longevity and improved hearing
conductivity. The stages of reconstruction demand an interdisciplinary team
approach. This presentation described a detailed step by step surgical and
prosthetic procedure of fabricating an implant retained auricular prostheses
for Saudi patients who lost their ears in a motor vehicle trauma.

Periodontal plastic
surgery: An update
Prof.
NADIR BABAY
Professor in Periodontics, Department of Preventive Dental Sciences, College
of Dentistry, King Saud University , Riyadh, Saudi Arabia
The main goal of periodontal therapy is to improve
periodontal health and thereby to maintain a patient's functional dentition
throughout his/her life. However, aesthetic represents an inseparable part of
today's oral therapy and several procedures have been proposed to preserve or
enhance patient aesthetics. Mucogingival surgery evolved into periodontal
plastic surgery first suggested by Miller in 1988
with various techniques designed to produce root coverage in areas of marginal
tissue recession, to augment deficient ridges, lengthen crowns in cases of
excessive gingival display, prepare the periodontium for restorative dentistry,
and reconstruct and preserve the gingiva
papilla in dental implant therapy, . Periodontal plastic surgery not only
enables the dentist to reconstruct but also to regenerate lost tissues. This
new term encompasses a much broader definition which more accurately reflects
the current evolution in surgical techniques which enhances the function and
esthetics of the periodontal tissues enabling the patient to improve the
appearance of the smile. The available plastic surgery procedures and their
clinical applications will be reviewed in this presentation with an emphasis
placed on factors to consider for proper case selection and ideal treatment
planning.

Single tooth replacement with implant vs.
conventional strategy
Dr. ABDULLAH S. AL KERAIDIS
Consultant in Prosthodontics and Implant, Director,
Riyadh Dental
Center , Riyadh
Medical Complex, Riyadh, Saudi Arabia
A fixed partial denture (FPD) is an important prosthetic
option in prosthodontic treatment in case of a single missing tooth. The conventional fixed prosthesis must
fulfill biological, mechanical, and esthetic requirements to be considered
successful. The high success rate of osseointegrated implant cause the
practitioner to think of using single implant to support a missing crown which
also reduce or eliminate the severe loss of enamel of the neighbouring natural
teeth. For many years, osseointegrated implant research has basically been
focused on the osseous inter-face and its functional capacity. Recently,
attention has been given to the tissues that surrounded the implant, providing
a biological seal. So, implant that
support single tooth must also fulfill a biological, mechanical and esthetic
requirements to be considered successful. A twenty minutes presentation with
clinical cases will elaborate the implant criteria to help the practitioner the
best way to choose between the two prosthetic options based on clinical
literature evidence.

SEM evaluation of canal
wall dentin following use of Hero Shaper and Race rotary Ni-Ti systems
Prof. RAJAB E. SAIF
Professor, Conservative Dental Science Department, Faculty
of Dentistry, King Abdulaziz UniversityJeddah, Saudi Arabia
This study was undertaken to evaluate using scanning electron
microscopy (SEM) root canal walls following preparation in vitro using two different rotary Ni-Ti instruments.
Statistically significant (P<0.01)
was found between the apical third, middle third, and coronal thirds for both
groups. No difference was observable between instrumentation groups. These data
revealed that both instruments produced a clean and debris-free canal in the
coronal and middle thirds but were unable to produce dentin surface-free from
smear and debris in the apical third.
