[Ultrastructural aspects of root planing: scanning electron microscopy (S.E.M.)].

The basis of Periodontal treatment is represented by scaling and root planing. The aim of this study was to compare root morphology after the use of three currets: a new Hu Friedy Gracey 7/8, a semi-new Hu Friedy Gracey 7/8, a worn Hu Friedy Gracey 7/8. The research indicates that manual treatment with the new curette is effective in removing tartar but can cause excoriations on the enamel of the tooth.

[Oral respiration. Diagnosis and physiopathology].

The oral breathing can change the functional connections during the development of the facial bones of the children. All this causes an abnormal growth of the facial bones and of the dental structures. This work developed a new discipline to remove this problem.

[The crevicular fluid in diabetics before and after initial periodontal treatment].

In this study gingival crevicular fluid was used as a parameter to estimate the efficacy of initial treatment in diabetic patients. The patients with diabetes had significantly more gingival inflammation before initial treatment than after. A Periotron with Periopaper was used to measure gingival crevicular fluid.

[Initial preparation for periodontal therapy].

The purpose of the present investigation was to test concept that initial treatment is effectual to maintain gingival health. The principal local aging factor is represented by plaque accumulation and gingival inflammation. The results of this study have proved that initial treatment is effectual only on pockets measuring less than 4 mm to periodontal probing.

[Granulosa cell myoblastoma of the chin: clinical study].

An interesting of granular-cell Myoblastoma occurred on the chirny area of a patient bearer of an inferior dental prosthesis gives the starting point for a revision of all Histopathogenetic theory about the true origin of these rare and discussed neoformations mostly sealed on the oral cavity.
