Abstract:
Radiography plays an important role in dentistry especially in localization of the inferior alveolar
canal (IAC) where the mandibular nerve bundle passes. it may be damaged during treatment and
implants procedure. the importance of the canal measurement arises from many factors where it
may be positioned at different locations in the mandible.
The researcher studied, localized and assessed the IAC in order to avoid injury
during the maxillofacial surgery or during dental implant procedures in both
sides of the mandible and in both genders and compared the variables in the
Sudanese population with those reported in other nations (Asians) the study
was done in the period from November2010 to April 2011.
The study consisted 202 OPGs which were collected and analyzed using
computer, five measures were selected and studied for right and left side of
the jaw for male and female. The distances were measured in millimeters:
D1=distance between superior border of MC and 2nd molar,D2= distance
between superior border of MC and 2nd premolar,D3= distance from superior
border of MC to alveolar bone,D4= height of MC,D5=distance between MC
to mandible border. The collected data then correlated with age and gender so
as to find the variable with highest correlation coefficient.
The results showed that the D1,D 2, D3,D4,D5 were correlated linearly with
the age in both gender, and no significant difference were detected
when
comparing both sides of the mandibles in both gender . Significant differences
between males and females measurements were detected and also in the
Sudanese and other Asian populations.
