The study was performed to investigate the thickness of lamina dura of the human
teeth in periodontal disease, which obtained from the intraoral roentgenograms of the 122
cases taken by bisecting technic.
All films were divided into the different ages, the different sexes, and the different
location of the different teeth.
The obtained results were as follows :
1. Compared with the normal teeth, the thickness of lamina dura in periodontal disease
is increased in all of different ages, sexes and teeth.
A Average thickness of the whole cases.
Male Mx. teeth Mn. teeth
21-30 yrs. grp. 0.432mm 0.428§®
31-40 yrs. grp. 0.392mm 0.385§®
41-60 yrs. gro. 0.411mm 0.422§®
Female Mx. teeth Mn. teeth
21-30 yrs. grp. 0.459mm 0.452§®
31-40 yrs. grp. 0.405mm 0.433§®
41-60 yrs. gro. 0.385mm 0.401§®
2. Generally, the alveolar crest portion is the thickest among the root surfaces, and
midroot, apex followed, and the average thickness of the posterior teeth is thicker than
that of anterior teeth.
3. The mean value of the whole maxillary teeth is almost same as that of mandibular
teeth.
4. On the whole cases, the differences of male and female is about 0.01§®, which is
not a significant differences.
