INTERPROXIMAL CONTACT AREA AND WIDTH: RELATIONSHIP TO PERIODONTAL
PARAMETERS

Normah Y, Raja Azman A, Mohd Zulkarnain S
Objective: This study focuses on investigating the influence of the interproximal contact
area and width on periodontal parameters. Materials and methods: A total of 30
periodontitis subjects were involved in the study, and 661 teeth were selected for
analysis. Periodontal parameters such as plaque score, gingiva score, clinical probing
depth and radiographic bone level were recorded for each tooth. Upper and lower
impressions were taken for construction of study models which were used for the
measurement of interproximal contact area and width. simple linear regression (SLR) and
multiple linear regressions (MLR) analysis were used to evaluate the relationship between
periodontal parameters and interproximal dimension. Results: The SLR analyses
consistently showed that the interproximal contact area and width were both significantly
related with plaque score, gingiva score and bone level, and MLR analyses confirmed that
both the interproximal contact area and width were significant predictors for each plaque
score, gingiva score and bone level model. Conclusion: Within the limitation of the study,
we can conclude that the interproximal contact area and width have a significant
relationship with the presence of dental biofilm, gingival bleeding and bone level in the
subjects susceptible to periodontal disease.
