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

Abstract

The study aims to evaluate the morphological variation of mandibular condyle This analysis was composed of 450 digital orthopantomograms taken for routine investigation to assess the morphology of 900 condylar heads. Condylar morphology was classified into four types (oval, bird beak, diamond and crooked finger). Most common occurring shape were evaluated, symmetry of condylar shape and most common combinations of the condylar shapes present in population were assessed. Out of 900 mandibular condyle, type 1(oval) of condyle was the most commonly appearing shape (56 %), followed by type 3 (diamond), type 2(bird beak) and finally type 4 (crooked finger). Symmetry was seen in 74.2 % of the total sample with the oval-oval was the most commonly occurring. Routine use of orthopantomography can assist dentist in assessment of condylar morphology alterations. Oval shape was the most common in all age groups in males and females. More studies on Iraqi population evaluating mandibular condyle are needed to provide standardized values for mandibular anatomical parts.

Morphometric anlaysis of mandibular coronoid, condyle and sigmoid shape using panoromic view for personal identification in south Indian population

“…In this study, the articular and functional parts of the mandible (condyle) coronoid and intervening sigmoid notch were evaluated in panoramic radiographs. [ 6 ]…”

“…Changes can be brought about by pathologies such as ankyloses, condylar hyperplasia, infections, tumors, and fractures. [ 6 ] Even after growth cessation, the mandibular and temporal parts of the TMJ are both thought to maintain their capacity for remodeling. [ 15 ] Bone can change its shape by regulating bone formation and resorption, often responding to forces.…”

“…were used to evaluate the shape of the mandibular condyle, coronoid, and intervening sigmoid notch. [ 6 ] The shapes were interpreted as a triangular, round, beak, or flat coronoid process [ Figure 1A ], round, angled, convex, or flat condylar process [ Figure 1B ], and sloping, wide, or round sigmoid notch [ Figure 1C ].…”

“…Genetic determinants, hormonal variation in condyle, and coronoid itself can lead to different “shapes” of the sigmoid notch. [ 6 ]…”

Assessment of radiographic morphology of mandibular condyles: a radiographic study

“…Morphological variations depend upon developmental variation along with condylar remodelling to accommodate malocclusion, trauma and other pathological and developmental abnormalities [5]. Variability in the shapes and sizes of condyles helps to diagnose the TMJ disorders associated with malocclusions such as crossbite, deep bite, and open bite [6].…”
