Abstract:
Objective:To study the relationship between gingival thickness(GT)and the underlying alveolar bone thickness(BT)in maxillary anterior region and the distance from cemento-enamel junction(CEJ)to alveolar crest.Methods:30 young volunteers with healthy gingiva were included.GT was measured at 2mm below the CEJ,buccal BT were measured at 3 locations:2,4 and 6 mm below the alveolar crest respectively,the distance from CEJ to alveolar crest were measured by CBCT and clinical direct measure respectively. Results:The correlation coefficient (r)values between GT and BT at 2,4 and 6 mm below alveolar crest were 0.493,0.383 and 0.342 (P <0.001 )respectively,the r value between GT and the distance from CEJ to alveolar crest was -0.21 3(P <0.01 ).No statistically significant difference was observed between CBCT and clinical measurements(t =-0.521 ,P =0.603).Conclusion:There is positive correlation between GT and BT at 2,4 and 6 mm below alveolar crest and negative relation between GT and the distance from CEJ to alveolar crest.
