ABSTRACT
Background: Knowledge about themorphological shapes of the coronoid process is useful for themaxillofacial surgeon. The Coronoid process can be easily harvested as a donor bone. It is also helpful in determining buccal vestibule during denture fabrication. Aim of the study: To find out the variation in shape of coronoid process and the intercoronoid distance in dry mandible of Maharashtra region. Material and Methods: One hundred and fifty seven (male 84 and female 73) dry mandible of Maharashtra region were studied for variations of shape in coronoid process of both sides and the intercoronoid distance . Results: Triangular shape coronoid process was found in 204 (64.97%), Hook shape in 66 (21.02%) sides. and rounded in 44 (14.01%) sides of mandible. Mean intercoronoid distance among males was found to be 9.2000 and 9.100 in females. Conclusions: It was found that most common shape of coronoid process found in our study was triangular. Mandible with hook shape coronoid process was almost equal in male and female mandible while triangular shape was slightly more in the male .
ABSTRACT
Aim of the study: Purpose of this study was to find out the most common position shape and direction of mental foramen in dry mandible of Maharashtra region. Background: Study of mental foramen is important for dentists in administering regional anesthesia and performing periapical surgery in the mental region of the mandible. Material and methods: Seventy five adult dry mandibles of unknown sex are studied for position shape and direction of mental foramen. All mandibles are studied for position shape and direction of mental foramen. Results: The most frequent position of mental foramen was in line with the longitudinal axis of the IInd premolar tooth. The shape of mental foramen was round or oval. Conclusions: Knowledge about morphometry of mental foramen is important for various dental procedure involving periapical region.
ABSTRACT
Background & objective: Foramen meningo-orbital is present in greater wing of sphenoid bone close to superior orbital fissure. It provide route for an anastomosis between the orbital branch of the middle meningeal artery and recurrent meningeal branch of ophthalmic artery. Basic textbooks of anatomy stated that it was a rare occurrence but some recent studies indicate a more frequent incidence of this which shows side and gender variation. These discrepancies were verified in our research work. Methods: We studied 150 dried human skulls (100 male and 50 female) of known sex. Only patent foramina were included in the observation. Results: Incidence of foramen as whole was 44.33% (male- 37.5% and female- 58%). In 4%, it was present bilaterally. Average distance between lateral end of superior orbital fissure and foramen was 6.22 mm. Conclusion: Our study indicates that a foramen meningo-orbital is present as often as, mostly unilaterally and multiple foramina may exist and also it shows side and genders variation. Knowledge of it may be of surgical significance to ophthalmologist and neurosurgeons and for radiologist because it masquerading as an intraocular foreign body. Further detail study on this topic in other populations from different areas is required.
