A qualitative and semiquantitative SEM study of the morphology of the biofilm on root surfaces of human teeth with endodontic-periodontal lesions.

Over the last decades, scanning electron microscopy (SEM) proved to be invaluable for ultrastructural investigation, allowing imaging of the overall appearance and/or specific features of oral biofilms, e.g., microbial colonies and individual cells, glycocalyx, the presence of inorganic products.

Changes in clinical and microbiological parameters of the periodontium during initial stages of orthodontic movement in patients with treated severe periodontitis: A longitudinal site-level analysis.

Applying orthodontic braces makes oral hygiene difficult and increases plaque accumulation, frequently resulting in gingival inflammation. In patients with previous severe periodontitis, this inflammation overlaps with the pre-existing inflammatory challenge and can lead to further progression of periodontal attachment loss. The aim of this study was to assess longitudinal site-level changes as mirrored by clinical and microbiological parameters during the initial remodeling of alveolar bone and the periodontal ligament, produced as an effect of light orthodontic forces in adult patients with severe periodontal disease that underwent standard (non-surgical and conventional surgical) periodontal therapy.

Early Childhood Oral Health Impact Scale (ECOHIS): Literature review and Italian validation.

Objective: The Early Childhood Oral Health Impact Scale (ECOHIS) is a questionnaire to elucidate the relationship between parental perception of the quality of life of their preschool children and their oral health status. Aim of the present work was to validate an Italian ECOHIS version and review the literature.

Methods: After adapting the original ECOHIS questionnaire from English to Italian (I-ECOHIS), I-ECOHIS was administered to parents of children afferent to the Dental Clinic of the University of Campania "Luigi Vanvitelli," regardless of age.

A comprehensive evaluation of an OFDI syndrome from child to teenager.

Orofaciodigital syndrome (OFDS) is a collective term for a rare inherited disorder that displays a wide phenotypic and genetic heterogeneity. The findings of diagnostic are the combination of the characteristic oral, facial and digital anomalies. In this heterogeneous group, the diagnosis of OFDI focuses on the association of the oro-dental, digital and cerebral malformations, polycystic kidney disease and several other manifestations.

Assessment of orthodontic biomaterials' cytotoxicity: an in vitro study on cell culture.

Objective: Orthodontists use various biomaterials such as molar bands, brackets, archwires, transpalatal archwires, facial masks and other auxiliary devices. One of the essential properties of these materials should be the biocompatibility. The aim of this study was to evaluate the biocompatibility of some orthodontic biomaterials like stainless steel archwires, brackets and NiTi (nickel-titanium alloy) coil springs.

Examination of Bolton Index comparing the traditional method with a 2-dimensional digital measurement method.

Unlabelled: Index is one of the most important analyses in orthodontic treatment planning. It shows if there is a correct proportion in size between the maxillary and mandibular teeth. In this study we compared the digital and traditional method.

Study of dental and skeletal disorders in mono- and dizygotic twins.

Unlabelled: The aim of this study was to analyze and to compare the dental and skeletal morphology of mono- and dizygotic twins (MZ and BZ).

Material And Methods: 10 sets of monozygotic (mean age: 18.5 years) and 10 sets of dizygotic (mean age: 19.
