Histological evaluation of oral maintenance programs upon gingival condition in orthodontic patients.

The aim of the study was to conduct a histological evaluation of gingival condition in patients under orthodontic treatment with fixed appliances, according to different oral hygiene maintenance programs. We performed a randomized prospective study on 36 patients with fixed orthodontic appliances (17-25 years of age) divided in three study groups. The investigations were represented by measurements of plaque index and sulcular bleeding index, followed by pathological examination of specimens from gingival tissue.

Considerations on morphological abnormalities of permanent teeth in children with cleft lip and palate.

Oral clefts are commonly associated with dental anomalies of number, size, shape, structure, position and eruption affecting both dentitions. Dental malformations may affect the development, growth and functions of the dento-maxillary apparatus (chewing, aesthetics, speech). The purpose of this paper was to assess the dental morphological variations in a group of patients with cleft lip and/or palate (CLP), as compared with a group of healthy subjects.
