  A morphological survey of root grooves and their influence on periodontal attachment loss

Prashant A. Bhusari a, Rajan Chopra b'*

Periodontal health reflects a balance between harmful and protective elements in the gin­gival marginal area. The total plaque mass, specific periodontopathogens, the tooth morphology and local environmental factors may challenge this balance. The periodontal ligament attachment loss shifts this balance adversely towards the periodontal disease. Objectives: The aim of this retrospective study was to determine the significance of proximal root grooves as a risk factor in the periodontal attachment loss; the effect of their dimensions and loca­tions has been evaluated.Materials and methods: One hundred (100) extracted formalin stored single rooted permanent ante­rior teeth were studied by staining with 0.1% toludine blue to visualize attached periodontal liga­ment remnants. On each tooth, the loss of attachment was measured from the cemento-enamel junction to the most coronal level of the stained periodontal ligament remnants. Results: The prevalence of proximal root grooves, was found to be 81% and a statistically signif­icant greater loss of attachment was present on grooved than on non-grooved surfaces (p < 0.01). Conclusions: Generally, there was direct relationship between groove location, its dimensions and maximum loss of attachment. The results suggest that proximal root grooves should be considered in periodontal diagnosis, prognosis and treatment planning.
