Apexification is a process of forming a mineralized apical barrier and had been performed by using calcium hydroxide paste, due to its biological and healing performances in cases of existent trauma. This clinical report aims to report the results of a 16-year follow-up study of an apexification treatment applied to nonvital tooth 22 of a healthy 8-year-old male after a trauma. Clinical inspection of the tooth showed fractures of the incisal edge and mesial angle, absence of coronal mobility, and negative pulp vitality under cold testing. Radiographic analysis of the root revealed incomplete apex formation. The possibility of fracture into the root or luxation injury was rejected, and the diagnosis of pulp necrosis was verified. Apexification by calcium hydroxide and subsequent endodontic treatment were planned. Initial formation of the mineralized apical barrier was observed after 3 months, and the barrier was considered to be completed after 8 months. Clinical, radiographic, and CBCT examinations after 16 years verified the success of the treatment, although the choice of calcium hydroxide for apexification treatment is discussed.

Radiolucent Lesion

<span>Periradicular lesions occur in non-vital teeth as the result of a chronic aggression by the presence of microorganisms into the root canal, which may appear as a radiolucent lesion in the radiographic exam; treatment varies according to surgical or nonsurgical methods. This case report describes the regression of a periradicular lesion using a nonsurgical endodontic treatment in association with intracanal calcium hydroxide-based medicament. After patient examination and radiographic analysis, a 13 mm (in maximum diameter) radiolucent lesion was observed in tooth number 12. The endodontic treatment was done and Calen-CMCP (S.S. White Artigos Dentários Ltda., Rio de Janeiro, RJ, Brazil) was placed into the root canal, which was changed after every two weeks during two months. It was observed a progressive centrifugal regression of the lesion after every renewing of the medicament. In addition, after six-year follow-up the tooth was still free of re-infection and bone tissue was completely regenerated. In conclusion, calcium hydroxide therapy can conservatively stimulate the regression of large periradicular lesions.</span>

Horizontal Root Fracture

Root fractures can involve the dentin, cementum, and pulp and commonly can occur as oblique fractures with varying orientations. The aim of this study was to demonstrate the maintenance of pulp health in a tooth with a fractured root without any endodontic treatment and to discuss the advantage of cone-bean computed tomography (CBCT) compared with traditional radiographs in the diagnosis of oblique root fractures. Intra-oral radiography of tooth 11 revealed a horizontal root fracture at the level of the apical third, while the sagittal CBCT slice reveals a complete fracture line running obliquely from the apical third on the buccal aspect through the cervical third on the palatal aspect.  Four years follow-up, the tooth has kept its pulp vitality, no tooth discoloration or discrepancy in arch position, without endodontic treatment. This result illustrates spontaneous healing of root fracture including preservation of pulp health. In addition, it confirms the importance of exams in 3 dimensions to correctly locate the fracture and assist in the treatment decision.

The aim of this paper was to, on the basis of everyday clinical practice analize the effect of a homeopathic remedy, as a complementary remedy in endodontic therapy of endoperiodontal lesions and chronic apical periodontitis and to radiologically check its effect on the flow and speed of reparation of damaged periodontal tissues. Endodontic therapy was done according to the usual protocol for the therapy of infectious canals with root canal preparation, medication with calcium hydroxide points and hermetic obturation with AH-26 paste. During endodontic treatment patients were taking homeophatic remedy Hepar sulfuris per os three times daily. The remedy stimulates the natural defences mechanism of the organism. Radiological follow up after three months period showed obvious reductiont of radiologic radiolucency in periapical region.

Long Term Follow Up

Patients with rheumatoid arthritis who had undergone total ankle arthroplasty and had a minimum of 2 yr follow-up were studied. Of the original 21 patients 17 were available for review. Twenty-three ankle replacements with an average follow-up of 5.6 yr were studied. On follow-up 2 ankles were rated excellent, 13 were rated good, 4 were rated fair, and 4 were rated poor. Thus, 83% were satisfactory on follow-up. Radiographic analysis revealed migration and settling of the talar component in 14 of 15 cases. Bone cement radiolucencies were found in 14 of 15 cases. Bone cement radiolucencies were found in 14 of 15 tibial components with tilting in 12 of these components. The postoperative position of the implant did not correlate with the development of radiolucencies or migration of the implant.

Determinant Factor

ABSTRACTObjective: The purpose of this study was to evaluate if the apical third enlargement of root canal is the determinant factor for the repair of periapical lesions in endodontic treatment.Methods: Eighty upper and lower incisors, canines and premolars with periapical lesions were randomly divided in 2 groups and were treated by undergraduate students. Canals were instrumented with up to 3 files in group I (n = 40) and up to 4 files in group II (n = 40) 1 mm short of the apex and were filled with a calcium hydroxide dressing. After removing calcium hydroxide 14 days later, both groups were filled using the lateral condensation technique. In the 2-year follow-up, a few patients did not return, and some cases did not present conditions for accurate comparisons. Therefore, only 43 patients (24 in group I and 19 in group II) presented conditions for radiographic comparisons. Data were statistically analyzed using Fisher's exact test.Results: Comparison of the initial and follow-up radiographs showed that 22 out of 24 (91.67%) patients in group I and 17 out of 19 patients (89.47%) in group II showed repair. Statistical analysis revealed no significant differences between the groups (P>.05).Conclusion: The results of this study show that the apical third enlargement did not alter the outcome of endodontic treatment of teeth with periapical lesion performed by undergraduate students.

Regenerative Endodontic Treatment

Regenerative endodontic treatment was performed on a mature maxillary premolar diagnosed as chronic pulpitis. The root canals were chemomechanically prepared and placed intracanal medicaments at the first appointment. Then 2 weeks later, a blood clot was created in the canals, over which mineral trioxide aggregate was placed. At 6-month follow-up, cementum-like tissue seemed to be formed in the root canal along with nearly recovered pulp vitality. At 12-month recall, the radiographic results revealed evidence of root wall thickening. At 30-month recall, no periapical lesion was found. This case report indicates that regenerative endodontic treatment for the mature premolar is feasible. More cases are needed for further validation.

Main Components

Scanning microscopy was used to study the surface of human gallstones and the surface of fractures. The specimens were obtained by operation, washed with water, dried at room temperature and shadowcasted with carbon and aluminum. Most of the specimens belong to patients from a series of X-ray follow-up study, examined during the last twenty years. So it was possible to evaluate approximately the age of these gallstones and to get information on the intensity of growing and solving.Cholesterol, a group of bile pigment substances and different salts of calcium, are the main components of human gallstones. By X-ray diffraction technique, infra-red spectroscopy and by chemical analysis it was demonstrated that all three components can be found in any gallstone. In the presence of water cholesterol crystallizes in pane-like plates of the triclinic crystal system.
