Evaluation of Mandibular Condylar Morphology By Orthopantomogram In Bangladeshi Population

Abstract

Background: Orthopantomograph (OPG) is one of the most common radiograph use by dental surgeon for evaluate information about teeth, Maxilla, Mandible and other bony structure. It is also available, low price and low doses of radiation. Mandibular condyle is most important landmarks of mandible, which is changes due to ageing process, developmental abnormalities, distinct diseases, trauma, endocrine shock, radio therapy etc. Panoramic radiographs remain the best screening modality for temporomandibular joint abnormalities today. Objectives: The aims at objective of observing and documentation of shapes of condyle on an orthopantomogram, which were very important for treatment of patient in different branch of dentistry specially in oral and maxillofacial surgery.
 Materials and Methods: This study composed radiographic evaluation of 500 condylar heads after imaging 250 digitalized OPGs taken for analysis. Then evaluate the mandibular condylar shape in 2D dimensional view (OPG).
 Results: In our study, an attempt to common prevalent radiographic shapes of the condylar head on the OPG. 200 pairs of condylar heads were evaluated. Out of them 60% were oval in shape, followed by bird beak (29%), diamond (9%) and least being crooked finger (2%). Oval-oval was commonly occurring mix (67%), whereas crooked/ crooked finger was a rarity.
 Conclusion: Due to low radiation exposer and availability, OPG is common chose of dentist for primary evaluate the tooth, mandible and facial skeleton. Shapes of the mandibular condyle also evaluate by OPG which showing ovaloval being most accepted in both genders.

A Panoramic Study of the Morphology of Mandibular Condyle in a Sample of Population from Basrah City

“…There was no significant difference between age groups in the present study (Table II), this finding goes in line with the results reported by several previous studies (Sahithi et al;Nagaraj et al;Ashwinirani et al, 2018;Anisuzzaman et al).…”

“…As a part of the TMJ, Mandibular condyles may undergo changes in morphology throughout the life in response to functional loading. Changes in morphology of mandibular condyle may be caused by various causes as: infections, trauma , tumors, condylar hyperplasia and ankyloses (Anisuzzaman et al, 2019).…”

Bentuk dan posisi kondilus sebagai marker pada Temporomandibular Disorder (TMD) melalui radiografi panoramik

“…5 Ada juga yang mengklasifikasikan kondilus rahang bawah manusia menjadi lima tipe : pipih (flattened), pointed, bersudut (angled), bulat (round), dan crooked finger. 6,7 Variasi bentuk kepala kondilus normal terjadi akibat faktor usia, jenis kelamin, tipe wajah, daya oklusal, dan tipe maloklusi. Kondilus mandibular mengalami perkembangan sejak awal kehidupan dan mengalami modifikasi sepanjang kehidupan sebagai bentuk adaptasi dengan daya fungsional.…”

Using Panoramic Radiograph for Identification of Mandibular Structures: A Study on Bangladeshi Population

“…[4][5][6][7] In the Bangladeshi population, mandibular condyle and anatomical variation of mental foramen in OPG was identified in different studies. [8][9] But, visibility of all the structures of mandible and their relation with age or gender was not examined before. The aim of our study to evaluate the visibility of six anatomical structures of mandible mandibular foramen, mandibular canal, mental foramen, anterior loop of mental nerve, incisive canal, lingual foramen and to determine the relationship between age or gender with visibility of these structures.…”
