Mouth is the first area for the food to be in contact with oral
epithelia and it could cause a chain of events initiated thermal
injuries (because of eating or consumption of hot food)
leading to ulceration epithelial hyperplasia or dysplasia and
end by carcinoma. The elaboration of the food makes it risque
to evaluate the role of various dietary components about oral
carcinogenesis. Broiling or frying foods and the utilization of
microwave increase oral cancer chance. The way is too long
in this field and it needs more studies to focus on oral cancer
especially oral squamous cell carcinoma (OSCC). In this
review we attempt to clarify the impact of some diet items on
oral carcinoma.

Poor image quality in self processed films is not an
uncommon problem despite following the manufacturer\'s
instructions, this matter has its influence on the ultimate
diagnosis when the radiographic examination is the backbone
in this diagnosis. The present study was carried out to
investigate this problem and to provide a guideline measure to
overcome it. One hundred fifty films were processed using
three different manipulations: message, shaking and a
combination of both, the resultant film quality was measured
and comparison was made the results showed that
combination of message and shaking procedure yield
significantly better results regarding image quality in
comparison to the other two procedures.

Introduction: In oral surgery practice the student needs to
implement wide scope of acquired theoretical knowledge.
This knowledge includes theoretical understanding of
intertwined biomechanics of teeth and jaw bone structures. In
addition, student should have suitable relevant medical
knowledge with direct and indirect influence of different
medical conditions on oral surgical procedures. Through
addressing students concerns and performances within two
related previous studies within this research project it might
be possible to utilize single patient information sheet for both
diagnostic and surgical dental education. Aim of the study: To
improve dental students\' cognitive skills through unified
diagnostic and technical training approach. Materials and
Methods: One hundred and nineteen 5th year dental students
from College of Dentistry, Almustansiriyah University,
agreed to participate in the study. The students were asked to
state their preference toward each question in oral medicine
and oral surgery information sheets. Descriptive and analytic
statistics were performed using SPSS Ver.23. Results:
students prefer oral medicine items in different levels. The
highest level of difference is shown in history of present
illness (HPI) item. This has been statistically confirmed.
Detailed types of question have shown to be the main reason
for preference compared to other reasons. The second reason
for preference was easiness of questions. This has been
statistically confirmed (p<0.05). Conclusion: Based on this
study within the context of the research project, a standard
patient information sheet items is suggested for a single
department under the name of oral diagnostic and surgical
department for undergraduate dental education.

X-ray has been employing in Iraq widely, but there are no
valuable measurements for radiation dosages. In purpose for
evaluation of radiation hazard emitted from using x-ray
instrument in the medical diagnostic.
This study use performed for five X-ray centers in Salah-din /
Iraq we are using film badge method the measurement
efficiency of these techniques was 70%. Empirical relation to
estimate the radiation dose from X-ray with relative error not
exceeds 30%.
The result of measurements radiation dose from diagnostic is
different from instrument to anther because the different of
the exposure value which used and is not conformed the value
of recommended. By using the exit dose from the body to
limit entrance dose values for any thickness without used to
increase the radiation dose.

Foramen magnum that is positioned under the sagittal suture
and surrounded by the lateral, squamous, and basilar parts of
the occipital bone is one of the most important structures in
the
(1)
(3)
base of the skull. Genetic, socioeconomic, and
environmental factors have a significant impact on sexual
dimorphism in FM dimensions which is population-specific.
The present retrospective study was carried out in Sulaimani
teaching hospital, Sulaimani, Iraq. The study sample
consisted of 100 adult patients including 50 females and 50
males aged 20-70 years. All of the patients had CT scanned
for their necks and heads over the period June 2017 to March
2019. In order to examine the foramen magnum, its sagittal
diameter, transverse diameter, area, index, and circumference
were measured. Student’s t-test and histogram were used to
analyze the data, and Receiver Operating Characteristic
(ROC) curve and Binary Logistic Regression model were
employed to obtain a model for sex determination. We found
that women had a lower average value than men in our study.
According to the independent t-test results; the genders were
significantly different in terms of all measured parameters
(p<0.05). As demonstrated by the ROC curve, the
predictability of the dimensions in sexing the crania for
sagittal diameter, transverse diameter, and area of foramen
was respectively 76.0%, 66.0%, and 74.0%. The current study
indicated a high percentage of sex predictability regarding the
dimensions, areas, and circumference, which is because of the
highly significant difference between the genders.

The orthodontic appliance may interfere with the removal of
plaque, and interfere with the gingival health. Inflammation
of the gingiva may start in patients wearing orthodontic
appliance who do not maintain proper oral hygiene. As the
parts of the orthodontic appliance associated with food
deposits
and
bacterial
accumulation.
This plaque
accumulation around the orthodontic appliance may lead to
periodontal tissue inflammation and caries in teeth. The aim
of this study was to determine the effect of fixed orthodontic
appliance on the health of periodontium. The indices like
plaque scale (PLS) gingival scale (GS) ,bleeding scale (BS).

To evaluate the occurrence of the most common tongue
developmental anomalies in patients attending the teaching
hospital of the University Of Baghdad\ College Of
Dentistry and determine their distribution between males and
females (2018-2019).Examination of 700 patients was done
clinically by the use of probe and dental mirror. The patients
age that was included was from (30-39) years old. The
developmental anomalies were more in females (66%) than
males and were widely distributed at age of 39years (20%),
while the lowest percentage was recorded at the age of 30
(2.6%). The most widely distributed anomalies of the tongue
was the fissure tongue 40%. The anomalies that were found to
be most prevalent were fissure tongue and followed by
geographic tongue and some of them were associated with
each other and they found to be increasing with age. They
were more in females than in males.
