Introduction: Immature permanent teeth that evolve to pulp necrosis represent a challenge for endodontic treatment. Regenerative endodontics and pulp revascularization techniques appear as a dynamic and potentially ideal field for clinical therapy in teeth with incomplete root development. Objective: To review the literature on pulpal revascularization techniques in the treatment of teeth with absence of pulp vitality with immature root apex. Methods: The descriptors “pulp revascularization”, “pulp necrosis”, “immature permanent tooth”, “revascularization”, “revitalization”, “dental pulp” and “regeneration” were used to obtain articles in English that presented content available in full and published in the last 15 years. Works of case reports and/or series of cases were excluded. Conclusion: Reviewed articles presented a heterogeneity of results regarding the effectiveness of the pulp revascularization technique, since the established criteria for determining success varied among the authors. The material most commonly used in the technique used consists of the Mineral Trioxide Aggregate (MTA) in paste consistency applied on blood clot with induced formation inside the canal. A shortage of laboratory and clinical studies on pulp revascularization techniques and materials that support its indication has been observed, which represents a potential gap in the literature and requires caution in the indication of this technique.

Alveolysis is a bone-gingival pathology characterized by the exposure of the dental root in the oral cavity, due the reabsorption of the alveolar bone, commonly related to dental trauma and/or dental caries. It is a condition of low occurrence, and usually affects male children between 4 and 5-years-old. The aim of this case report was to present a clinical case of alveolysis in a deciduous anterior tooth in a 6-year-old child with a history of dental trauma in the anterior region of the maxilla. The lesion was diagnosed after routine clinical examination. The intraoral examination revealed the radicular apex of the tooth 61, surrounded by slightly edema and erythematous tissue, and ulceration of the labial mucosa related to the exposed apex. The tooth involved had no caries, only slight fracture at the incisal angle. The patient presented an unsatisfactory oral condition, characterized by the presence of visible dental biofilm and severe early childhood caries. The radiographic exam revealed root resorption on tooth 61 and the presence of the maxillary permanent central incisors in conditions of normality. The diagnosis was of alveolysis with apical fenestration. The treatment of choice was the dental extraction of the involved tooth. There was no intercurrence during the treatment and the postoperative was satisfactory, considering the normal eruption of the successor tooth and the restoration of the child's ideal oral health conditions. Thus, it can be concluded that alveolysis is a condition of easy diagnosis, simplified treatment and good prognosis. [ABSTRACT FROM AUTHOR]

Endodontic treatment of immature teeth with necrotic pulp and incomplete root formation has been recently treated with pulp revascularization. It is a promising alternative treatment to promote apical closure and root development. To date, a variety of revascularization protocols have been described, however little is known about the success of combining mechanical instrumentation and intracanal medication such as calcium hydroxide or triantibiotic paste. Thus, the aim of this study is to present a review of literature of pulp revascularization protocols and its clinical implications for treatment of teeth with pulp necrosis and incomplete apex. The causes that usually interrupt the root formation are dental traumatisms and caries, which can lead to pulp necrosis. Therefore, the immature permanent teeth and pulp necrosis were usually treated by apexification or the confection of an apical MTA plug, in order to accomplish the formation of an apical barrier. However, by this method, the roots canal walls remain thin and fragile. It may be concluded that the pulp revascularization treatment is an alternative approach for immature permanent teeth with pulp necrosis. However, there is not a standardized protocol that is considered ideal in these cases. [ABSTRACT FROM AUTHOR]

The gingiva is a part of the masticatory mucosa that covers the alveolar process and surrounds the cervical portion of teeth, being composed of free or marginal gingiva and attached gingiva, both constituted by keratinized mucosa. Gingival recession is one of the most common mucogingival defects and is characterized by apical positioning of the margin in relation to the cementoenamel junction and root exposure. The symptoms related to their presence may be manifested by root hypersensitivity (especially triggered by thermal or contact stimuli) and also by gingival sensitivity to toothbrushing and mastication, especially when the marginal tissue is composed of alveolar mucosa (BORGUETTI et al., 2002). Its etiology is considered multifactorial, and the anatomic aspect is fundamental. The early diagnosis is important for both prevention and treatment (GORMAN & O'LEARY, 1967).Periodontal plastic surgeries should be considered in cases of progressive recession. Thus, several surgical techniques have been developed to correct these defects (CASATI et al., 2001). This paper presents the semilunar flap technique with coronal positioning and its advantages for treatment of these buccal and proximal gingival defects.It was concluded that the success of treatment is based on its etiology and proper surgical planning, and the results achieved were satisfactory according to the criteria for evaluation of mucogingival surgeries.
