The present report describes two pulpotomies performed in a child patient, in the first permanent lower molars with open apex, without the presence of periapical lesions. Pulpotomy consists of removing the coronary pulp and maintaining the vital root pulp, with the insertion of a biocompatible capping material. This procedure is indicated for patients with young permanent teeth, as it is a minimally invasive treatment, allowing continued root formation, and allowing greater longevity of the element. Bioceramic repair cements have been the material of choice in conservative pulpal treatments, due to their excellent biological and physical-chemical properties, providing extremely strong results.

Background: Regenerative endodontic procedures (REPs) have emerged as a promising treatment option for young permanent teeth with pulp necrosis, offering the potential for tissue repair and preservation. Materials and Methods: A retrospective analysis was conducted on a cohort of 30 patients aged 8 to 16 years with pulp necrosis in young permanent teeth. The patients underwent REPs, including disinfection, triple antibiotic paste application, and a coronal barrier. Clinical and radiographic data were collected at baseline and follow-up appointments at 6, 12, and 24 months. Radiographs were analyzed for root lengthening, apical closure, and resolution of periapical lesions. Results: The mean increase in root length after 24 months was 3.42 mm (SD ± 1.12 mm), and 90% of cases demonstrated complete apical closure. The overall success rate, defined as the absence of clinical symptoms and radiographic evidence of pathology, was 80%. Conclusion: REPs show promising outcomes in young permanent teeth with pulp necrosis, promoting root development, and apical closure. [ABSTRACT FROM AUTHOR]

Management of immature non-vital teeth poses challenge for the clinician owing to the thin root canal walls and open apices which may show apical divergence. Apexification is the technique of inducing the apical closure with a root end filling material for non-vital immature young permanent teeth. Traditionally, Calcium hydroxide was the material of choice for apexification of immature permanent teeth but introduction of MTA has shown remarkable promise as an alternative to calcium hydroxide. This report presents a case of apexification of anterior two young permanent teeth with open apices using MTA and Gutta percha followed by esthetic build up using cast metal posts and full coverage restorations.

Introduction. Direct pulp capping in young permanent teeth consists of the application of a biocompatible material to the pulp exposed for mechanical or traumatic reasons, to preserve its vitality and complete its apicogenesis. Objective. To carry out a bibliographic review of the most commonly used materials for its realization and their effect on the pulp tissue. Conclusion. The restorative potential of the dentin-pulp complex and the success rate of the veneering treatment is influenced by the correct selection of the ideal material, capable of stimulating the formation of restorative dentin, maintaining pulp vitality, bactericidal or bacteriostatic, adhere to restorative material, sterile, radiopaque and providing a good seal.

Objectives To determine the pulp vitality after traumatic injury, dentists often use pulp sensitivity tests, which can be ambiguous in young permanent teeth with incomplete root formation. Transmitted-light plethysmography (TLP) is a non-invasive objective method that uses a 525-nm LED to detect blood volume change in the pulp. The present study aimed (1) to investigate pulpal blood flow with TLP and optical characteristics in healthy permanent maxillary incisors in different root formation stages, and (2) to assess the influences of body growth of the children and tooth color on the TLP amplitude. Design Seventy-eight fully erupted maxillary central incisors were divided into four groups, according to the root formation stages. Group 1: root with wide-open apex, Group 2: root completed in length with open apex, Group 3: root with half-closed apex, Group 4: root with complete formation. The TLP amplitude, optical density, electric pulp testing, and cervical tooth color measurements of each group were compared using a one-way analysis of variance followed by the Bonferroni method. The correlation between the weights/heights of children and TLP amplitudes was analyzed using Pearson coefficient. Results The TLP amplitude was significantly higher in Group 3 than in the other groups. The amplitude was correlated with the weights/heights of children, but not with the tooth color. Optical density and electric sensitivity increased with tooth maturation. Conclusion The amplitude of TLP and optical density may be affected by growth and development in children and indicate changes in the vascular dynamics of the pulp and hard tissue maturation during root formation stages.

Objective · To observe the effects of custom made fiber posts on the fracture resistance of young permanent teeth treated with calcium hydroxide for different time. Methods · Forty-five extracted human young permanent teeth (premolar) were selected and randomly assigned to 9 groups. One group was the control group and the rest 8 groups were treated with conventional root canal preparation. Of these 8 groups, 4 groups (FI, FIII, FIV, FIX) were restored by custom made fiber posts after being treated with calcium hydroxide for 1, 3, 6, and 9 months respectively, and other 4 groups (CI, CIII, CIV, CIX) were not restored by custom made fiber posts. All samples underwent fracture strength tests and their fracture modes were analyzed for the possibility of second repair. Results · The fracture load was decreased with the treatment time after being treated with calcium hydroxide for 1 month (P<0.01). The fracture loads in groups restored by custom made fiber posts were increased after being treated with calcium hydroxide for 6 and 9 months (P<0.05, P<0.01). After being treated with calcium hydroxide for 1 month, groups restored by custom made fiber posts were likely to have fracture modes that facilitate the second repair as compared with groups not restored by custom made fiber posts (P<0.05). Conclusion · The restoration by custom made fiber posts can increase the fracture resistance of young permanent teeth treated with calcium hydroxide for medium and long term ( ≥ 1 month).

The completion of root development and closure of the apex occurs up to 3 years after the eruption of the tooth. The treatment of pulpal injury during this period provides a significant challenge for the clinician. The importance of careful case assessment and accurate pulpal diagnosis in the treatment of immature teeth with pulpal injury cannot be overemphasized. The treatment of choice for necrotic teeth is apexification, which is induction of apical closure to produce more favorable conditions for conventional root canal filling. The most commonly advocated medicament is calcium hydroxide, although recently considerable interest has been expressed in the use of mineral trioxide aggregate (MTA). We report a case series wherein calcium hydroxide and MTA were used successfully for one step apexification in teeth with open apex. [ABSTRACT FROM AUTHOR]

Objective: The aim of this study was to compare the clinical efficacy of new caries detecting dye Caries Check Blue (CCB) with Caries Check (CC) and Caries Detector (CD) using a laser fluorescence device (DIAGNOdent).Method: Primary and permanent teeth with dentin caries were stained with polypropylene glycol (MW=300) based new caries detecting dyes CCB, CC, or propylene glycol (MW=76) based CD. In the CCB and CC groups, stained dentin was completely removed. In the CD groups, pink-stained dentin was retained according to the manufacturers' instructions. Cavities before and after caries removal were measured with the DIAGNOdent. Data were analyzed using ANOVA and Fisher's PLSD multiple comparison test at alpha=0.05. Regression analyses were performed between DIAGNOdent readings and scores obtained from the clinical parameters.Results: The DIAGNOdent readings after caries removal were: primary-CCB (13.2+/-10.4), primary-CC (14.3+/-16.7), primary-CD (9.0+/-5.2), permanent-CCB (22.7+/-13.4), permanent-CC (10.6+/-6.8) and permanent-CD (9.7+/-9.0). Significant differences were identified between the permanent-CCB and all other groups. Correlation coefficients between DIAGNOdent readings and clinical parameters were low.Conclusions: When dentin stained with Caries Check Blue or Caries Check was completely removed, the DIAGNOdent readings were higher than those recorded when palely-stained pink dentin was retained with the Caries Detector, with significant difference observed for the permanent-CCB group. Caries Check Blue may be used clinically to avoid excessive removal of caries-affected or sound dentin in permanent teeth but not in primary teeth. [ABSTRACT FROM AUTHOR]

Abstract: Objective: This study evaluated the clinical efficacy of a new caries detecting dye using a laser fluorescence device (DIAGNOdent). Method: Primary and permanent teeth with dentin caries were stained with Caries Check (CC), containing 1% acid red in polypropylene glycol (MW=300) or Caries Detector (CD), containing 1% acid red in propylene glycol (MW=76). Primary-CC, primary-CD, permanent-CC and permanent-CD groups were prepared. In the CC groups, stained dentin was completely removed. In the CD groups, pink-stained dentin was retained according to the manufacturers’ instructions. Cavities before and after caries removal were measured with the DIAGNOdent. Data were analyzed using ANOVA and Fisher''s PLSD multiple comparison test at α =0.05. Regression analyses were performed between DIAGNOdent readings and scores obtained from the clinical parameters. Results: For all groups, there were no significant differences in the DIAGNOdent readings before treatment. The DIAGNOdent readings after caries removal were: primary-CC (16.0±17.6), primary-CD (9.6±5.2), permanent-CC (11.0±7.0) and permanent-CD (7.1±3.8). Significant differences were identified between the permanent-CC and primary-CD, and permanent-CC and permanent-CD subgroups but not for the primary subgroups. Correlation coefficients between DIAGNOdent readings and clinical parameters were low. Conclusions: When dentin stained with Caries Check was completely removed, the DIAGNOdent readings were higher than those recorded when palely-stained pink dentin was retained with the Caries Detector, with significant difference observed for the permanent teeth. Caries Check may be used clinically to avoid excessive removal of caries-affected or sound dentin in permanent teeth but not in primary teeth. [Copyright &y& Elsevier]

Fluorosis staining is commonly considered an esthetic problem because of the psychological impact of unesthetic maxillary anterior teeth. Numerous treatment approaches have been proposed, ranging from bleaching to enamel reduction to restorative techniques. Bleaching of hypomineralized enamel lesions, using 5% sodium hypochlorite, has been useful clinically. The technique described, in this case, appears to have advantages over other methods for improving the appearance of fluorotic lesions. It is simple, low cost, noninvasive, so the enamel keeps its structure, relatively rapid, and safe; it requires no special materials, and it can be used with safety on young permanent teeth.
