The evolution of the concepts of growth followed the path and evolution of life concepts. In order to better understand and to explain some aspects of intrauterine growth, and differentiation, modern physiology sought to decipher the most intimate aspects of the placentar filter, the way in which all the influences of the external environment represented by the mother’s body are sent. Aim of the study: the aim was to avoid problems of differential diagnosis with other diseases of the orofacial system. For the purpose of conducting the research, we categorized the etiological factors of the dysfunction in the primary (they are mainly of a systemic nature, their role is hard to be highlighted), secondary (the usual clinical examination, with emphasis on the impact of vicious habits on occlusal caractristics) and thirdly (tests for the examination of psychoemotional and behavioral characteristics as well as the assessment of stress level were performed). Materials and methods:The study was conducted on a sample of 320 subjects who presented themselves at the Pediatric Dentistry Clinic in Galati for various dental treatments without accusing any obvious dysfunctional symptomatology, 120 patients presenting frequent vicious habits. Of these, 56 male (46.66%) and 64 female (53.33%). Results and disussions:Vicious habits are frequent in the critical periods of development of the dento-maxillary apparatus, exerting on it a bad influence. The sucking habits can have their fingers, the lips, the back of the hand, various objects or even tongue.Visual habits break the muscle balance and disturb the growth of the bones giving a new direction of their growth, in the sense of traction and pressure, producing changes in the position of the teeth, arches and jaw bones. Orthodontic treatment works on the basis of the biological principle of dento-maxillary apparatus integration in the general unity of the body, the balance of which develops and maintains according to the hereditary dowry and the influences of the environmental conditions; it is strictly individual; measures and treatment methods vary from one patient to another depending on the individual characteristics and the stage of child development. Conclusions: The various clinical forms of dento – maxillary abnormalities characteristic of each age stage are due to the association of different vicious habits and the intensity or duration of these functional disorders.
Key words: dental abnormalities, heredity, vicious habits, orthodontic treatment.
