Access and isolation problem solving in endodontics: anterior teeth.

Through a pictorial presentation of case studies, this paper examines the versatility of alternative methods of retention as a means of improving the overall access to the endodontically-involved tooth. Successful endodontics is the result of precise biomechanical instrumentation involving procedural manipulations that depend on a complete and unobstructed approach to the working field. This pictorial essay is aimed principally at clinicians who would ordinarily reject rubber dam isolation in those cases where the clinical pretreatment conditions are anything but ideal.

Adhesive restoration of an endodontically treated incisor.

Glass-ionomer cement and composite resin can be used in combination for restoration of an endodontic access preparation. Adhesive restorations using these materials avoid the problems of marginal leakage and tooth discoloration, characteristic of silver amalgam restorations, and preclude the need for complete-coronal restoration. A detailed clinical procedure for placement of a stratified glass-ionomer cement and composite resin restoration for an endodontically treated permanent incisor is described.

Molar endodontics.

Molar endodontics is an extensive and complex subject. The treatment of molar teeth has deservedly taken a position of elevated importance in recent years. No longer are the molar teeth a target for extraction forceps, but are more often nowadays a target for crowns. Patients and dentists alike are striving to keep the marvellous molars and, with this in mind, the pillars of the future crowns and bridges must be preserved. Endodontic treatment of molar teeth is basically no different from treating the simple, single, straight canal. The principles of complete debridement, obturation and restoration are the same. The stumbling blocks confront us in the way of anatomical variations, difficulty with isolation and access and, probably the simplest and most crucial factor, time. Given the devotion of enough time, patience, and practice, the desired result will be achievable.

Clinical diagnosis and treatment of endodontic and periodontal lesions.

Because of the intimate relationship of the root canal system and the periodontium, developing endodontic and periodontal lesions may mimic each other in clinical and radiographic appearance. The etiology, diagnosis, treatment, and prognosis of endodontic and periodontal lesions will be discussed.

Endodontic therapy in a postirradiated child: review of the literature and report of a case.

Exodontia of extremely carious teeth leads to a significant risk of osteoradionecrosis in patients who have undergone radiotherapy. In these patients, endodontic treatment could be an alternative. Successful root canal therapy in a girl who had been irradiated for head and neck neoplasms is reported. The results indicated that use of calcium hydroxide to obturate the root canals is a viable method of postirradiation endodontics in primary teeth.

Rehabilitation of the endodontically treated tooth: exploding the myths, defining the future.

Recent advances in the science and technology of porcelain and the biomaterials associated with adhesive dentistry, are effecting a shift towards a more conservative approach to the restoration of endodontically treated posterior teeth. These new materials and techniques enable the practitioner to approach old problems from a different perspective and thereby achieve unique and innovative solutions. The historical, often anecdotal approach to the restoration of endodontically treated teeth, is being replaced by a scientifically determined rationale that takes into account the biology and biometrics of pulpless teeth.

Nonsurgical re-treatment of endodontic failures.

Endodontic treatment has a very high percentage of success. When failures did occur, many were re-treated with surgery, although nonsurgical re-treatment often was an option. Recently, improvements in instruments for use in endodontic surgery have increased the ability to perform such re-treatments. Even so, this author believes that nonsurgical re-treatment is preferable to surgical intervention whenever possible because of the greater comfort to the patient and the increased indication of failure for amalgam reverse fillings. Advice for recall appointments and evaluations and the correct procedures for re-treating common failures without surgery are presented. These include failures caused by short or incomplete canal fillings, overextended canal fillings, untreated major canals, and chronically draining teeth.

Advances in endodontic surgery: Part 1.

It is generally accepted that non-surgical endodontic therapy eliminates periapical inflammation or infection and allows teeth to be restored that previously might have been extracted. However, failure does occur in a small percentage of cases. When confronted with such cases the clinician should be prepared to initiate alternative procedures, including surgery, to enhance the rate of success. This, the first of two articles, describes refinements in endodontic surgical techniques and introduces the research that has been used to develop new materials and devices.

[The role of the traditional radiological methods in conservative therapy and endodontics].

The traditional radiographic examinations used in restorative dentistry and endodontics are: intraoral radiograph performed in the beta-wing or the paralleling technique, the partial extraoral radiograph (rotational narrow beam), the panoramic radiography and the periapical radiographs with the bisecting technique which is particularly suitable for visualization of the apex. Radiology is a valuable diagnostic means to evaluate the extension of primary caries, to identify secondary and interproximal initial decays and if required let the therapist measure the biological width. Several factors influence the radiographic interpretation of caries: cervical burnout, mach band effect, internal and external resorption, restorative materials for fillings and sub-bases, abrasions and/or erosions. Radiology allows the diagnosis of developmental and acquired abnormalities of the teeth which can have an influence on the treatment itself. Examples are: variations in the shape of the crown and root, dens in dente, enamel hypoplasia, dentinogenesis imperfecta. Radiograms are of major importance in the evaluation of restorative dentistry results: precision of the margins, congruous contact points, fractures. Moreover, it provides the endodontic procedures with useful diagnostic data and permits the measurements during the treatment, supplying the immediate and long term checks too.

A peripheral giant cell granuloma mimicking a combined endodontic-periodontic lesion.

This case report delineates an instance whereby a peripheral giant cell granuloma mimicked certain features of an endodontic-periodontic lesion. When the area did not resolve following endodontic therapy, and in fact actually increased in size in a relatively short time, the decision to biopsy the area was made. After histologic examination, a definitive diagnosis of peripheral giant cell granuloma was possible. The patient is being monitored postoperatively to ensure no recurrence of the lesion. The relevance of this case report is that it exemplifies the fact that the lesion may be encountered by periodontists, and that the lesion may clinically resemble a mucocele or peripheral ossifying fibroma.

Treatment outcome of surgical and non-surgical management of endodontic failures.

The principal modalities available to manage endodontic treatment failures are orthograde retreatment and apical surgery. Both modalities have specific advantages, clinical implications, and risks, and their selection involves a complex decision-making process. A review of the literature pertaining to the treatment outcome of each modality was undertaken to establish an objective reference for practitioners involved in the management of endodontic treatment failures. Based on a weighted average calculation of the results reported in the reviewed studies, the orthograde retreatment of teeth associated with apical periodontitis results in a success rate of 66 per cent, an uncertain healing rate of 11 per cent, and a failure rate of 23 per cent. Apical surgery results in a success rate of 59 per cent, an uncertain healing rate of 22 per cent, and a failure rate of 19 per cent. These figures are discussed with reference to the characteristics of the reviewed studies. It appears that many of the reviewed studies have lesser relevance today, due to the current technical improvements in both treatment and modalities.

Conventional endodontics and the operating microscope.

Patients are increasingly wishing to undergo conventional endodontic treatment rather than to risk the loss of a tooth. Endodontic treatment in teeth that have been previously restored with extensive intracoronal or extracoronal restorations are often difficult to treat. The orientation of the root canals to the crown of the tooth may be lost, and this may often be compounded by the deposition of reparative dentin in the pulp chamber. The operating microscope allows better visualization of the working field, ensuring that the anatomy of the tooth is more readily inspected. This greatly enhances the clinician's ability to locate extra root canals and therefore increase the likelihood of a successful outcome. It should not be forgotten that the operating microscope also has a place in other fields of dentistry, especially restorative dentistry, and is an asset to both the specialist and the generalist.

Hemostasis in endodontic microsurgery.

There are numerous ways to achieve hemostasis. With the abundance of hemostatic agents available and with the introduction of new products, one has to make an objective decision. A good agent achieves hemostasis within a short period of time, is easy to manipulate, is biocompatible, does not impair or retard healing, must be relatively inexpensive, is reliable, and works best for the particular surgical procedure. With these purposes in mind, the following sequence is recommended to achieve hemostasis during endodontic microsurgery. I. Presurgical: Give 2 to 3 Carpules of 1:50,000 epinephrine local anesthetic with multiple infiltration sites throughout the entire surgical field. II. Surgical: A. Remove all granulation tissue. B. Place an epinephrine pellet into the bony crypt followed by dry sterile cotton pellets. Apply pressure for 2 minutes. Remove all the cotton pellets except the first epinephrine pellet. Continue with the surgical procedure and remove the epinephrine pellet before final irrigation and closure. C. Alternatively, calcium sulfate can be mixed into a thick putty and packed against the bone cavity. Because it is a biodegradable material, calcium sulfate can be left in situ. In fact, in large bone defects and through-and-through lesions, additional calcium sulfate can be placed to fill the entire bone cavity as a barrier material. Healing is more predictable with little chance of scar tissue formation. Calcium sulfate resorbs in 2 to 4 weeks. D. Small bleeding sites in the bone can be brushed with ferric sulfate solution. III. Postsurgical: Tissue compression before and after suturing cuts down on postsurgical bleeding and swelling. Hemostasis is imperative in endodontic microsurgery for better visualization, a good environment for placement of retrograde filling material, and a more efficient surgical procedure with less blood loss.

Barrier membrane techniques in endodontic microsurgery.

The ultimate goal in endodontic microsurgery is the predictable regeneration of periapical tissues. One of the main concerns in treating an endodontically treated tooth which has a through-and-through osseous defect is that incomplete bone healing may be inevitable. This article reviews the use of different barrier membranes for bone regeneration. In addition, the indications, techniques, and prognosis of calcium sulfate in guided bone regeneration are presented.

Anaerobic flora in endodontic infections.

Microbiological and clinical data from 56 patients with endodontic infections were evaluated. Samples were collected using autoclaved paper points. Specimens were processed for isolation of aerobic and anaerobic bacteria. Antimicrobial sensitivity and resistance profiles of the recovered isolates was also performed. Forty nine positive cultures (87.5%) were obtained from the 56 consecutive necrotic root canal systems which were sampled. A total of 69 aerobic bacteria and 21 anaerobic bacteria were recovered. Aerobic bacteria were isolated from 35 patients (72%), anaerobic bacteria from 3 (6%) and mixed aerobic and anaerobic bacteria from 11 patients (22%). The most common aerobic isolate was Klebsiella pneumoniae. The predominant anaerobic isolate was Bacteroides species. One isolate was recovered from 25 patients (51%) whereas in the remaining 24 patients (49%) more than 1 isolate were recovered. These data illustrate the polymicrobial nature of endodontic infections in half the patients studied and the role of anaerobic bacteria in a quarter of them.

Endodontic considerations in the geriatric patient.

Endodontic needs of today's and tomorrow's growing older adult population present increasing challenges for dental care providers. Biologic and anatomic differences in the dental tissues between older and younger patients must be understood and considered in treatment planning and performance for appropriate endodontic procedures. These differences generally do not contraindicate treatment, which, when performed correctly, will be successful in the elderly patient.

Cortical bone resorption secondary to endodontic-implant pathology. A case report.

A single implant was inserted to replace the mandibular right lateral incisor in a 50-year-old Caucasian woman. After one month, an endodontic lesion formed on the adjacent canine, which went on to engulf the fixture. Even though endodontic therapy was instituted expeditiously on the canine, the implant exfoliated spontaneously the following month. There was a large radiolucency afterwards, suggesting resorption of both the labial and lingual cortical plates. A follow-up radiograph four months later revealed a residual detect along with delayed wound repair.
