Morphological study of proximal root grooves and their influence on periodontal attachment loss

Abstract

Background:The etiology of periodontal diseases is multifactorial including both systemic and local causes. Local factors such as grooves on root surfaces contribute a great deal to the causation of periodontal diseases.Materials and Methods:Proximal radicular grooves were studied in 150 extracted maxillary and mandibular anterior teeth. Periodontal attachment loss was measured after staining the root surfaces with 0.1% toluidine blue stain. The relationship of the presence and absence of grooves with periodontal attachment loss was also studied.Results:The prevalence of proximal root grooves was found to be 86.67%. The prevalence of grooves on maxillary teeth was 43.42% and on mandibular teeth was 56.67%. A greater loss of attachment was present on grooved surfaces than on nongrooved surfaces.Conclusion:The proximal radicular grooves present as one of the major etiological factors in periodontal diseases.

Identification of Lower Central Incisors

“…With the objective of understanding the morphology of the grooves present in the proximal surfaces of the roots of the upper and lower anterior teeth and its effect on the loss of periodontal insertion, Kaur et al [10] evaluated 300 proximal surfaces of 150 teeth. The prevalence of proximal root grooves was 86.67%.…”
