Vital root amputation. A clinical and histological study.

An investigation was designed to study the clinical and histological effects of delaying endodontic therapy for a period of 2 weeks without dressing of the exposed pulp, after vital intentional root amputation had been carried out on periodontally involved teeth. From the results obtained it was possible to conclude that: 1. Endodontics, prior to surgical root amputation, remains the treatment of choice. 2. When preoperative endodontics is not possible, the approach used in this study will provide good results without severe, adverse clinical or histological effects. 3. The altered periodontal condition and tooth form do not interfere with the performance of definitive endodontics 2 weeks after surgery. 4. Definitive preparation of the cut tooth surface at the time of root amputation facilitates maintenance of oral hygiene after removal of the periodontal dressings. 5. The high percentage of involvement of the distobuccal root of the first maxillary molar in periodontal situations requiring correction by root amputation, may be due to the anatomy of this root.

Mineral trioxide aggregate as a pulpotomy agent in primary molars: an in vivo study.

The retention of pulpally involved deciduous tooth in a healthy state until the time of normal exfoliation remains to be one of the challenges for Pedodontists. A scientific noise has been generated about several materials some of which have been popular pulpotomy medicaments. Concerns have been raised about the toxicity and potential carcinogenicity of these materials, and alternatives have been proposed to maintain the partial pulp vitality, however to date no material has been accepted as an ideal pulpotomy agent. Mineral trioxide aggregate (MTA) is a biocompatible material which provides a biological seal. MTA has been proposed as a potential medicament for various pulpal procedures like pulp capping with reversible pulpitis, apexification, repair of root perforations, etc. Hence the present study was done to evaluate the efficacy of MTA as a pulpotomy medicament. A clinical and radiographic evaluation was done on children where MTA was used as pulpotomy medicament in primary molars for a period of 6 months and it was found to be a successful material.

Endodontic management of taurodontic teeth.

Taurodontism is a morpho-anatomical change in the shape of the tooth in which the body of the tooth is enlarged and the roots are reduced in size. Although taurodontism is a dental rarity, this unusual radicular form should merit circumspect considerations in planning and treatment. Endodontic management in taurodont teeth has been described as complex and difficult. The present paper describes the successful completion of endodontic treatment in three taurodontic teeth with appropriate use of instruments and techniques and also emphasizes the need for post endodontic rehabilitation.

Guided tissue regeneration in the management of severe periodontal-endodontic lesions.

Diagnosis of combined periodontal-endodontic lesions can prove difficult and frustrating. They are often characterised by extensive loss of periodontal attachment and alveolar bone, and their successful management depends on careful clinical evaluation, accurate diagnosis, and a structured approach to treatment planning for both the periodontic and endodontic components. Recent advances in regenerative periodontics have led to improved management of periodontal-endodontic lesions. This paper reviews the management of such lesions in light of these recent advances and illustrates this through reports of two patients who had severe periodontal involvement.

Calcium hydroxide and a corticosteroid-antibiotic association as dressings in cases of biopulpectomy. A comparative study in dogs' teeth.

The subject of this paper was to study the behavior of the periapical tissues of dogs' teeth after biopulpectomy and dressing with calcium hydroxide or a corticosteroid-antibiotic association, before root canal filling with zinc oxide eugenol (ZOE) or Sealapex sealers. The teeth were overinstrumented and dressed for 7 days before the root canal filling. The animals were sacrificed 180 days after treatment and the specimens were prepared for morphological analysis. Specimens treated with Sealapex presented a higher number of cases with biological closure than ZOE. When the root canals were filled with ZOE, better results were observed with the use of the Ca(OH)2 dressing.

[Improved model of cryosprayer].

For local congelation of pathologically altered sections of the tissue the design of an earlier devised cryosprayer has been improved. The newly constructed model is convenient in handling, reliable in operation, has low weight and overall dimensions and ensures good visual view of the operation field. The new model of the cryosprayer is recommended for use in the stomatological practice, for treatment precarcinous affections of the buccal mucosa and dental pulp.

Evaluation of the carbon dioxide laser on vital human primary pulp tissue.

PURPOSE: The purpose of this study was to evaluate the response of the human primary pulp to the carbon dioxide laser and formocresol for vital pulp therapy. METHODS: Fifteen healthy children with intact, caries-and-restoration-free, contralateral primary cuspids with at least two-thirds of the roots remaining who were scheduled for orthodontic extraction were randomly assigned to pulpotomy treatment with a carbon dioxide laser or formocresol. The treated teeth were clinically and radiographically evaluated at 28 and 90 days post-treatment prior to extraction. The extracted teeth were evaluated histologically for pulpal response. RESULTS: All teeth were asymptomatic and clinically normal at both observation periods. Internal root resorption was observed in one formocresol and two laser treated teeth. There was a significant inverse correlation between the laser energy applied to the pulp and the degree of inflammation at 28 days (P = .01) but not at 90 days (P = .27). CONCLUSION: Carbon dioxide laser treatment compared favorably to formocresol for pulpotomy in primary teeth.

[Vital or devitalizing extirpation?].

When extirpating the pulp, the canal tissue is amputated chemically or surgically and the space produced filled with non-irritating material. The resulting wound differs depending on the method applied. The difficulties in dressing are discussed, especially considering the so-called "dead space". After criticizing arsenic medication, the obtainable therapeutic success is discussed and the disadvantages and advantages of the two extirpation methods are compared.

A new approach to the basic principles of endodontics.

The basic principles on which successful endodontic therapy depends have been commonly accepted as (1) debridement, (2) sterilization and (3) obturation. Each of these principles is subjected to critical evaluation. Because of the morphological complexity of most root canals complete debridement is not possible. No sampling technique is yet available to ensure total sterility of the prepared root canal nor is it possible to ensure that the root canal system is hermetically sealed by the filling material. Although it has been shown that 43 per cent of biopsies from the periapical area of endodontically involved teeth show evidence of cyst formation, the fact that up to 90 per cent of cases show evidence of healing following endodontic treatment without surgery indicates that radicular cysts can resolve without surgical intervention. In the light of these findings it is suggested that the basic principles should be accepted as (1) adequate debridement, (2) adequate obturation and (3) trephination where indicated.
