                    <jats:title>Background:</jats:title>
                    <jats:p>Non-Inflammatory Destructive Periodontal 
Disease (NIDPD), is a severe destructive periodontal disease, that is 
characterized by the attachment loss and alveolar bone loss, without signs of 
the gingival inflammation, and the periodontal pocket development.</jats:p>
                </jats:sec>
                <jats:sec>
                    <jats:title>Objective:</jats:title>
                    <jats:p>Despite 
the fact that various cases of NIDPD have been reported; their etiology and 
disease evolution is still indefinite, and therefore, are open for discussion.</jats:p>
                </jats:sec>
                <jats:sec>
                    <jats:title>Method:</jats:title>
                    <jats:p>An NIDPD case was studied in order to demonstrate features of the 
disease, and discuss the possible etiology and treatment.</jats:p>
                </jats:sec>
                <jats:sec>
                    <jats:title>Results:</jats:title>
                    <jats:p>In 
this clinical case, the etiology of NIDPD seems to be an association of 
endogenous opportunist bacteria with anatomical aspects, occlusion pattern, 
emotional stress and mouth breathing condition.</jats:p>
                </jats:sec>
                <jats:sec>
                    <jats:title>Conclusion:</jats:title>
                    <jats:p>In spite of 
all cases described in the literature are comparable and may have similar 
etiology as related in this clinical case, additional research is needed to 
identify and clarify the role of the etiologic factors which determine the 
disease.</jats:p>
