Arne Bjork conosciuto a livello internazionale per i suoi contributi alla comprensione della crescita cranio-facciale. La sua prima pubblicazione, The Face in Profile, 1947, lo fece conoscere in tutto il mondo. Bjork esercit come clinico in Svezia per 14 anni prima di trasferirsi in Danimarca nel 1951, dove presiedette il Dipartimento di Ortodonzia del Royal Dental College di Copenhagen. Questo libro si occupa dell'introduzione di Bjork e del suo contributo nel campo dell'ortodonzia.

Genetics is the study and understanding of the phenomena of heredity and variation. A large number of genes are associated with many systemic conditions. Periodontitis is inflammatory condition of periodontium. It is considered being a multifactorial disease. It has been proven that genetic factors impair inflammatory and immune responses during periodontal diseases. Focusing on genetic factors, currently variants in at least 65 genes have been suggested as being associated with periodontitis based on genome‐wide association studies and candidate gene case control studies. It is important to understand the significance of genetics in periodontics.

There is little doubt that the prevalence of patients with underlying medical condition seeking orthodontic care has increased over the past two decades. A pilot study performed in 2002 of several orthodontic practices revealed that more than 25% of patients seeking orthodontic therapy had some medical diagnosis that potentially impacted their care. While the general dentistry literature addresses many of these diagnosis and their medical and dental management, there is a paucity of information in the orthodontic literature as to the impact of these conditions on orthodontic care.

A number of systemic disorders increase patient susceptibility to periodontal disease, which moreover evolves more rapidly and more aggressively. The underlying factors are mainly related to alterations in immune, endocrine and connective tissue status. These alterations are associated with different pathologies and syndromes that generate periodontal disease either as a primary manifestation or by aggravating a pre-existing condition attributable to local factors. In the presence of qualitative or quantitative cellular immune alterations, periodontal disease may manifest early on a severe localized or generalized basis. In the presence of humoral immune alterations, periodontal damage may result indirectly as a consequence of alterations in other systems. There are variable degrees of consensus regarding the background systemic disorder, as in the case of Chediak-Higiashi syndrome, where antibiotic treatment proves ineffective; in severe congenital neutropenia or infantile genetic agranulocytosis, where antibiotic prophylaxis is suggested; and in Papillon-Lef vre syndrome, where an established treatment protocol is available.
