[Revascularization: a new treatment method in endodontics].

Recently a number of published articles concerning a new treatment method in traumatized young permanent teeth with a wide open apex that have lost vitality, with or without periapical lesions have shown success. This new treatment is entitled "Revascularization" and its aim is to promote root maturation in infected immature teeth with open apices. This procedure stimulates the formation of hard tissue as well as elongation and thickening of the dentinal walls and closure of the root apex. Sometimes the vitality of the teeth is regained. The aim of the present publication is to describe the revascularization technique and to clarify the indications of its use.

[Pre-septal orbital cellulitis from odentogenic origin--combined surgical and endodontic approach: a case report].

Orbital abscesses are common infectious diseases. The etiology of orbital abscesses may vary from common sinusitis in most of the cases, to cocaine sniffing. As a result of the proximity to the brain, orbital abscesses may complicate to life threatening situations. The infectious process spreads to the orbit in several ways: hematogenous, via anatomic spaces in the maxillofacial region, direct invasion. The treatment philosophy combines surgical and Antibiotic therapy to resolve the acute phase of the disease, followed by elimination of the source. The purpose of this paper is to report a case of pre septal orbital cellulitis, that was treated surgically combined with endodontic therapy. To describe the different subtypes of orbital abscesses, differential diagnosis, imaging and treatment options.

Endodontic treatment of developmental anomalies in posterior teeth: treatment of geminated/fused teeth--report of two cases.

AIM: Gemination or fusion is a rare occurrence in the mandibular posterior teeth. Endodontic treatment of these teeth needs special care and attention to the bizarre anatomy. The aim of this article is to describe the problems encountered and the strategy in treating such cases. CASE REPORT: Two cases of complex endodontic treatment of fused/geminated teeth are presented. The first is an 11-year-old girl with an anomalous 'double' first mandibular molar and premolar diagnosed as having necrotic pulp with chronic apical abscess of endodontic origin; the second is a 16-year-old boy with 'double' second and supernumerary mandibular molars, who was diagnosed with irreversible pulpitis. Both cases were treated successfully in multiple appointments. The common features and treatment modalities are discussed. KEY LEARNING POINTS: Failure to diagnose fused/geminated teeth leads to misdiagnosis and a treatment plan that could cause permanent damage and tooth loss. Generally, there is communication between root canal systems of fused/geminated teeth which should be treated as one entity. Use of magnification is an important aid during treatment.

The influence of social and ethnic factors on dental care habits and dental anxiety: a study in Israel.

The purpose of the present study was to assess the influence of social and ethnic factors on dental care habits and dental anxiety in a group of children resident in Jerusalem, Israel. Four hundred and fifty-six children completed a questionnaire that included 21 questions: nine referred to socio-demographic variables, three concerned the children's dental care habits, and the remaining nine concerned dental anxiety. Social level was determined by the father's occupation and their area of residence. Ethnic background was established according to the mother's or grandmother's country of origin. Chi-squared tests revealed no significant differences between social class or ethnic origin and dental care habits or dental anxiety. Analysis of variance, however, revealed a significant difference between the anxiety reported by boys of the two ethnic groups studied. Dental care habits were good in the majority of the children of all backgrounds, and the level of dental anxiety was low in all groups. It was concluded that ethnic origin had an influence on dental anxiety only in boys, whereas ethnic origin and social class had no influence on dental care habits.
