In the case reports, two different approaches have been described to treat the developmental disturbances in the maxillary central incisors due to trauma to its predecessor. The treatment plan was chosen according to the type and severity of the malformations, the exact location and the morphology of the involved teeth. In the first case, the disimpaction of the maxillary right central incisor was achieved with the combined of surgical and orthodontic therapy, that was planned in two consecutive stages. In the second case the severe root angulation and the failure of the previous orthodontic traction made impossible the repositioning of the upper right central incisor, which was surgical removed...

Background: The purpose of this study was to report the outcome of the management of both horizontal and vertical defects of alveolar crest using the bone slat technique approach in conjunction with third molar removal prior to implant placement in the aesthetic area. Methods: We present a 20-year-old female patient who lost a maxillary lateral incisor. The objective of treatment was to replace the lateral incisor with an implant-supported crown restoration without interfering with the integrity and topography of the adjacent gingival tissues...

Introduction: Cervicofacial subcutaneous emphysema is defined as the abnormal introduction of air in the subcutaneous tissues of the head and neck. It is mainly caused by trauma, head and neck surgery, general anesthesia, and coughing or habitual performance of Valsalva manoeuvre. The occurrence of subcutaneous emphysema after dental treatment is rare, and diffusion of gas into the mediastinum is much rarer, especially when the procedure is a nonsurgical treatment. Presented here is a case of subcutaneous emphysema that occurred after sodium hypochlorite irrigation during endodontic treatment, and the description of its etiologies and prevention during nonsurgical endodontic treatment...

Aim: To evaluate knowledge and attitude of caregivers/healthcare workers regarding oral health of special need patients, at a comprehensive rehabilitation centre. Material and methods: A validated self-administered structured questionnaire was used in an interview style among 120 caregivers at a comprehensive rehabilitation centre. The first part of questionnaire collected demographic information (age, gender, experience, literacy). The other part of the questionnaire was related to the knowledge and attitude of caregivers regarding importance of oral health including oral hygiene practices, cause of tooth decay, significance of fluoride, common oral problems and need for oral health education...

Aims: Cytokeratin 19 (CK-19) is an epithelium-specific intermediate filament protein that has been investigated in oral lichen planus (OLP) lesions but has not been compared with the expression of CK-19 in the OLP-related oral squamous cell carcinoma (OSCC). The aim of the present study has been to objectively compare the immunohistochemical expression of the CK-19 in OLP lesions and subsequent OSCC lesions that developed over time, to evaluate the change of the staining pattern among OLP and the grades of differentiation in OSCC...

Mandible condyle remodeling is a great challenge on craniofacial growth studies. The great majority of the reports deals with growing period. However, there is a great necessity to clarify the importance of functional stimulation on adult mandible condyle remodeling. By using an adult mouse model, we investigated the influence of mandible forwarding on condyle remodeling and gene expression by bone forming cells. Tomographic and scintigraphic evaluations showed sagittal growth and cell activity enhancement...

Introduction: Craniometaphyseal dysplasia is a rare hereditary bone disease presenting metaphyseal widening of the tubular bones, sclerosis of craniofacial bones and bony overgrowth of the facial and skull bones. Craniometaphyseal dysplasia occurs in an autosomal dominant (AD) and an autosomal recessive (AR) form. Case report: We present a 32-year-old patient arrived at our unit in May 2009. His main discomfort was a major limitation of the mouth opening, in the context of a craniofacial deformity...

Surgery to the mandibular third molar is common, and injuries to the inferior alveolar nerve and the lingual nerve are well-recognized complications of this procedure. The aim of these technical notes is to describe operative measures for reducing neurological complications during mandibular third molar surgery. The following procedure should be used to prevent damage to the inferior alveolar nerve: a well-designed mucoperiosteal flap, to obtain appropriate access to the surgical area; a conservative ostectomy on the distal and distal-lingual side; tooth sectioning, to facilitate its removal by decreasing the retention zones; tooth dislocation in the path of withdrawal imposed by the curvature of the root apex; and careful socket debridement, when the roots of the extracted tooth are in intimate contact with the mandibular canal...

AIM: The aim of the study was to report the use of an elastodontic therapy in a growing patient affected by Dentinogenesis Imperfecta, second class malocclusion, deep bite and lower arch crowding from the deciduous dentition to permanent one. CASE REPORT: At first, the 5-year-old patient was treated with an elastodontic device known as "Nite-Guide". When the patient was 7 years old, during her first permanent molars and incisors eruption and after optimal house-practices, an Occlus-o-Guide Series G was placed at night and on daylight (two hours a day) performing exercises aimed to activate facial muscles and facilitate the deep bite reopening...

REVIEW
Eshrak Sofan, Afrah Sofan, Gaspare Palaia, Gianluca Tenore, Umberto Romeo, Guido Migliau
Adhesive dentistry has undergone great progress in the last decades. In light of minimal-invasive dentistry, this new approach promotes a more conservative cavity design, which relies on the effectiveness of current enamel-dentine adhesives. Adhesive dentistry began in 1955 by Buonocore on the benefits of acid etching. With changing technologies, dental adhesives have evolved from no-etch to total-etch (4th and 5th generation) to self-etch (6th , 7th and 8th generation) systems. Currently, bonding to dental substrates is based on three different strategies: 1) etch-and-rinse, 2) self-etch and 3) resin-modified glass-ionomer approach as possessing the unique properties of self-adherence to the tooth tissue...

Chronic disc displacement may lead to long-term pain. Temporomandibular joint surgery is reserved for those patients whose symptoms remain severe despite conservative treatment. We looked at the of effect of modified meniscopexy on patients with chronic disc displacement without reduction who did not respond to non-surgical pain management treatment. In this retrospective study a total of 59 joints was treated and all patients except one underwent splint assisted bilateral meniscopexy: this patient had splint assisted unilateral meniscopexy...

OBJECTIVE: The association between obesity and periodontitis has been extensively investigated in adults but not in young people. The aim of this study was to examine the association between overweight-obesity and periodontal disease in pediatric subjects. METHODS: Controlled cross-sectional study involving 100 school children of both gender (50 M and 50 F) between 7 and 12 years of age (mean age 9,19±1,57). Two groups were formed based on Body Mass Index value: test group with BMI ≥ 25 Kg/m2 and control group with BMI ≤ 24 Kg/m2 ...
