“…The condyle located in the posterior area operates as the main center of regional adaptive growth. The regulation of its development is defined by genetic and epigenetic factors that modify the expression of transcription and growth factors 25 . The mandibular condyle is a secondary cartilage that it is not surrounded by a cartilaginous matrix, and is therefore not isolated from the influences of local factors.…”

“…The mandibular condyle is a secondary cartilage that it is not surrounded by a cartilaginous matrix, and is therefore not isolated from the influences of local factors. However, the condyle responds to functional and mechanical loads; its frequent stimulation triggers a series of events that increase the number of replicating mesenchymal cells 25 .…”

Previous studies by us demonstrated that the consumption of thermally oxidized oil diet adversely affects body growth, lipid metabolism, bone mass and femur biomechanical competence. Aim: The aim of this study was to evaluate the effects of a diet containing fried sunflower oil on the mandible of growing rats. Materials and Method: Male Wistar rats (21±1 day old) (n=21) were assigned at weaning to one of three diets for 8 weeks: a control diet (C), a diet containing sunflower oil (SFO) or a diet containing sunflower oil that had been repeatedly heated (SFOx); both SFO and SFOx were mixed with commercial rat chow at 13% (w/w). The consistency and viscosity of the 3 diets were similar. Zoometrics and food intake were recorded weekly. At wk=8, mandibular growth was assessed by measurements of anatomical points of cleaned bones, and mandible biomechanical competence was assessed to estimate the structural properties of the bone. Statistical analysis was performed by SPSS v. 20.0. Results: Rats fed SFOx diet attained the lowest final body weight (P=0.0074), mandibular weight (P=0.0001) and mandibular \length (P=0.0002). Load bearing capacity (Wf;N), load of yielding (Wy;N) and stiffness (Wy/dy;N/mm) of the mandible were negatively affected by both sunflower oil diets (fresh and fried) (P=0.001; P=0.002; P=0.003, respectively) though SFOx induced the most significant reduction in Wy/dy (C:44.4(5.4) > SFO:36.1(2.1) > SFOx: 26.3(3.7) N/ mm; P=0.003). The deleterious effect of SFOx on mandibular growth was more accentuated on the posterior part of the bone (C:11.4(0.3)=SFO:11.2(0.2)>SFOx: 10.7(0.2) mm; p=0.0005); the anterior/ posterior ratio (C:1.25(0.02)=SFO:1.27(0.02)<SFOx:1.32(0.03); p=0.0001) indicated that SFOx induced mandibular deformation. Conclusion: Consumption of SFOx diet during growth could affect mandibular morphometric properties and biomechanical competence, in terms of bone stiffness.
