The stomatologic investigation has revealed multiple caries in the youths of pre-conscription age with constitutionally conditioned malnutrition (CCM). Its specific features are the following: the high affection of incisor and molar teeth, the involvement as a rule of 3 dental surfaces, the high incidence of complicated caries (especially when the bode mass index is 16.69 + /- 0.25 kg/ m2), with the prevalence of acute apical periodontitis of pulpar origin and chronic periodontitis. The "bad" mark of oral cavity hygiene was more often noted in CCM youths, that causes the high incidence of gingivitis severe forms among them. The wide spread and high intensity of dental-and-maxillary anomaly and deformity connected with permanent lower molar early removal as well as the high incidence of desquamative glossitis are registered in the given patient group. The revealed patterns of incidence and intensity of oral and dental diseases in CCM youths show the necessity of more detailed study of their stomatologic status with the use of special clinical-and-laboratory methods in order to develop the optimal rehabilitation programs.
