Objectives: To assess long-term attachment and periodontitis-related tooth loss (PTL) in untreated periodontal disease over 40 years.
Material And Methods: Data originated from the natural history of periodontitis study in Sri Lankan tea labourers first examined in 1970. In 2010, 75 subjects (15.
Aim: To examine the lifelong effect of light smoking on periodontal health.
Methods: The data were derived from a 20-year longitudinal study of a group of Norwegian, middle-class males. The patients were subset according to their smoking history.
Background: The factors associated with initial periodontitis are not well understood and cannot be identified by cross-sectional studies.
Aim: To identify the factors associated with the initiation of chronic periodontitis using ante-dependence modelling.
Material And Methods: A 26-year longitudinal study of the natural history of periodontitis served as the basis for the study.
Aim: No long-term studies have reported on risk factors for tooth loss in subjects without home or professional dental care. The purpose of this report is to identify potential risk factors for tooth loss among male Sri Lankan tea labourers who participated in a 20-year investigation of the natural history of periodontal disease.
Material And Methods: Data for this report were obtained from the 455 subjects who participated in multiple examinations over the 20-year period from 1970 to 1990.
Aim: The purpose of this study was to assess the long-term influence of gingival inflammation on tooth loss.
Material And Methods: The data originated from a 26-year longitudinal study of Norwegian males, who practiced adequate daily oral home care and received "state-of-the-art" dental care. The initial examination in 1969 included 565 individuals aged between 16 and 34 years.
Aim: The purpose of this study was to assess the rate of attachment loss during various stages of adult life in a well-maintained middle-class population.
Material And Methods: The data originated from a 26-year longitudinal study of Norwegian males who had received regular and adequate dental care and practised daily oral home care. The initial examination in 1969 included 565 individuals aged between 16 and 34 years.
Aim: The purpose of this study was to assess the initiation and progression of periodontal disease during adult life.
Materials And Methods: In a 26-year longitudinal investigation of the initiation and progression of chronic periodontitis that started in 1969 and included 565 men of Norwegian middle class, 223 who had participated in some, but not all, intermediate examinations presented at the last survey in 1995. Fifty-four individuals were available for examination in all seven surveys.
Objectives: The purpose of this study was to determine the influence of long-standing gingival inflammation on periodontal attachment loss. On the basis of repeated examinations, the present report describes the influence of gingival inflammation on the initiation of periodontitis from 16 to 59 years of age.
Material And Methods: The data originated from a 26-year longitudinal study of Norwegian males, who practiced daily oral home care and received state-of-the-art dental care.
