--- Nutrition is a phenomenon peculiar and active living beings in their ongoing process of exchange with the environment Objective. Histomorphological effect the jaw albino rats subjected to proteindeficient diet with different iron concentrations assessed. Methodology. The sample consisted of 24 male albino rats Holzman; 21 days old, grouped into 4 experimental groups fed “ad libitum“ for 46 days; Group A (control) received 29 mg protein 10g.hierro. / 100 g., group B received 10g protein., 46 mg iron. / 100g; 5g protein C group. Iron 29 mg / 100g); Group D protein 5g., 46 mg iron / 100mg, The anatomical jaw (vertical longitudinal body thickness, vertical branch length) and lower first molar. (coronal and mesiodistal length) cell count analysis and structural elements of the dentin-pulp complex periodontal insertion and the condyle. Result. Existen histomorphological changes in the dentin-pulp, periodontal insertion and condyle translated in decreased cellular elements, earmark layer decreased, acellular obvious area wiel complex; periodontal membrane stage, presence of nodular isogenic groups, and hypertrophic in group C, columnar and nodular isogenic groups alternating with hypertrophic zones in group D condyle. In rats subjected to diet 5g protein, iron /100g.y 26mg 46 mg / 100g) groups C and D. Conclusions. Diets deficient in protein (5g protein, iron 29.46 mg / 100g), and different iron concentration, produces histomorphological effect the jaw rats; reducing dentin layer, pulp odontoblasts and fibroblasts, collagen fibers, reducing the number of fibroblasts, cementoblasts, osteoblasts, osteocytes and osteoclasts; fewer chondroblasts, chondrocytes. Decrease in body weight, length and thickness of the jaw; coronal mesiodistal length and diameter of the first molar of the rats. Keywords: jaw, protein, iron, -pulpar dentin complex
