Restoring teeth that are endodontically treated through existing crowns. Part I: Survey of pulpal status on access.

OBJECTIVE: The purpose of this study was to identify the pulpal findings encountered by practitioners when accessing complete-coverage crowns that require nonsurgical root canal treatment and the relevance of coronal leakage to the success of the RTC. METHOD AND MATERIALS: The survey package consisted of a cover letter stating the instructions, rationale, and purpose for the questionnaire, a questionnaire with 8 short-answer questions, and a stamped, self-addressed envelope. A randomized sample of active dentists (300 general practitioners, 300 prosthodontists, and 300 endodontists) was selected. Collected data were analyzed with the chi-square test. RESULTS: A 60% response rate was obtained. Statistically significant differences were found among the practitioner groups, depending on the question. General practitioners and endodontists obtain access through crowns and maintain these crowns as final restoration significantly more often than do prosthodontists. Practitioners responded that teeth with complete crowns require nonsurgical root canal treatment after 5 to 10 years. CONCLUSION: Respondents believe that leakage must be addressed when endodontic access cavities in artificial crowns are restored after nonsurgical root canal treatment. General practitioners perform nonsurgical root canal treatment more frequently than do prosthodontists. Practitioners indicated that when teeth with complete crowns require nonsurgical root canal treatment, treatment is most often performed 5 to 10 years after placement of the crown.

Treatment of teeth with open apices using mineral trioxide aggregate.

Injuries to the dentition may ultimately result in the interruption of root development. If the pulp remains vital following trauma, this state should be maintained and root-end closure should be induced by apexogenesis. When the pulp is necrotic, the placement of an apical barrier can be utilized as an alternative to establish an environment that facilitates the closure of the apical opening. This article demonstrates the use of mineral trioxide aggregate as an apical barrier material for root-end closure in the permanent teeth of three patients.

Pulp-dentin biology in restorative dentistry. Part 2: initial reactions to preparation of teeth for restorative procedures.

Pulpal complications involving inflammation, degradation, and necrosis are the result of a series of traumatic injuries. The restorative dentist must minimize the trauma to dentin and pulp inflicted during clinical procedures, including that inflicted during tooth preparation. Part 11 of this series discusses the structural and physiologic changes in the pulp-dentin complex that result from crown and cavity preparation and the clinical implication of these changes.

Pulpal inflammatory responses following non-carious class V restorations.

The effects of inflammatory activity following surgical intervention can injure pulp tissues; in severe cases it can lead to pulpal complications. With this article, the authors report on the effects of cavity preparation and restoration events and how they can interact together to reduce or increase the severity of pulpal inflammatory activity in 202 restored Class V cavities. Although some inflammatory activity was observed in the absence of bacteria, the severity of pulpal inflammatory activity was increased when cavity restorations became infected. Zinc oxide eugenol and resin-modified glass ionomer cement prevented bacterial microleakage in cavity restorations, with no severe inflammatory activity observed with these materials. Bacteria were observed in cavities restored with enamel bonding resin and adhesive bonded composites and were associated with severe grades of inflammatory activity. The cavity remaining dentin thickness influenced the grade of inflammatory activity. In the absence of infection, the grade of inflammatory activity decreased after 20 weeks post-operatively. In the presence of infection, the grade of pulpal inflammation remained stable until a minimum of 30 weeks had elapsed.

[Effects of periodontal disease and its treatment on the condition of the pulp].

Since there is a close relationship between the periodontium and the pulp, formed by the apical foramen, dentinal tubules, lateral and accessory canals, it is evident that both compartments influence one other. In this article, the influence of periodontal disease and its treatment on the dental pulp is described. The review shows that periodontal disease and its treatment, very seldom compromise the vital functions of the pulp, but can cause local pulpal response. A more common reaction is dentinal hypersensitivity. Although there's no clear treatment for dentinal hypersensitivity, this article presents a few guidelines for treatment.

[Clinical study on amoxicillin in otorhinolaryngological field (author's transl)].

Clinical effect of amoxicillin was evaluated in 29 cases of the acute infections of ear, nose and throat: 8 cases of acute purulent otitis media, one case of acute otitis externa, one case of furuncle of the ear, 2 cases of acute sinusitis, 12 cases of acute lacunar tonsillitis, 2 cases of pharyngolaryngitis, one case of acute cervical lymphadenitis, one case of phlegmon of the face and one case of acute gingivitis. The following results were obtained from the clinical and laboratory studies. 1) The therapeutic results were excellent in 18 cases, good in 5 cases, fair in 3 cases and poor in 3 cases. The effect was observed in 79.3% of the patients treated. 2) The causative bacteria were: 3 strains of beta-Streptococcus hemolyticus, 4 strains of Hemophilus, 4 strains of Staphylococcus aureus, one strain of Diplococcus pneumoniae, one strain of Gram-positive Diplococcus and Gram-negative Bacillus. Clinically good results were obtained in patients infected with beta-Streptococcus hemolyticus, Hemophilus and Diplococcus pneumoniae. 3) No side effect was observed with amoxicillin, except slight diarrhea in one case. This side effect disappeared by cessation of the administration. 4) No unfavourable influence was noticed on peripheral blood, liver function nor renal function by administration of amoxicillin. 5) From the results of this series, amoxicillin seems to be useful in the treatment of acute infections of the ear, nose and throat.

Pulp-dentin biology in restorative dentistry. Part 3: Pulpal inflammation and its sequelae.

Physiologic and histopathologic experimental studies over the last 30 to 40 years have demonstrated that the healing of the dental pulp is comparable to that of connective tissue elsewhere, despite its location in the low-compliance pulp chamber. The greatest difficulty from a clinical point of view is to assess cellular changes and vitality of the pulp. If it is vital, the potential for repair is present, especially in young individuals.

[Dental pain].

"The extreme variability of toothache is such that a good rule for any examiner is to consider all pains about the mouth and face to be of dental origin until provide otherwise" (Welden E. Bell). Dental caries is a disease of the calcified tissues of the teeth, characterised by demineralization of the inorganic portion and destruction of the organic substance of the tooth. The acids which affects the primary decalcifications is derived from the fermentation of starches and sugar logged in the retaining centers of the teeth. Dental caries can be classified in relation with the depth of the lesions: caries of the enamel, caries of the dentin, pulp diseases which are the result of dental caries in which bacterial invasion of the dentin and pulp tissue occurs, diseases of the periapical tissues which leads to periapical cyst, or to periapical abcess.

Pulp-dentin biology in restorative dentistry. Part 4: Dental caries--characteristics of lesions and pulpal reactions.

The infectious disease dental caries results in lesions that may affect enamel, dentin, pulp, and cementum. If a caries lesion has progressed to the stage at which it requires restorative intervention, it is important that the clinician understand the tissue changes in the dentin that are likely to have taken place during lesion development. Until the present, no major distinction between the restorative treatment of active (rapidly progressing) and arrested (slowly progressing) lesions has been made, despite the fact that the two conditions exhibit major differences in tissue changes in the pulp-dentin complex. Intratubular changes and tertiary dentin formation will affect the outcome of the restorative treatment. In unaffected dentin and in rapidly progressing lesions, permeable tubules persist, and when the preparation of carious teeth results in the opening of unaffected dentin, greater care must be taken in all phases of the restorative procedures than if the dentin is impermeable. An active, deep lesion can be changed to an arrested lesion by a two-step excavation approach. Optimal assessment of the prevailing clinical conditions can only be made on the basis of thorough knowledge of the biology of the pulp-dentin organ.

Intraradicular space: what happens within roots of infected teeth?

The pulpo-dentine complex is normally protected from exogenous substances in the oral cavity by the overlying enamel or cementum. Dental caries, dental trauma, enamel/dentine cracks, and restorative procedures commonly breach the integrity of enamel or cementum and may allow infection of the pulpo-dentine complex to occur, possibly leading to pulp and periapical inflammatory disease. Infection of the intraradicular space is a complex and dynamic process involving interactions between host and microbial factors. An understanding of these factors has led to the development of endodontic techniques that offer predictable success.

Biocompatibility of a resin-modified glass-ionomer cement applied as pulp capping in human teeth.

PURPOSE: to evaluate the human pulp response following pulp capping with calcium hydroxide (CH, Group 1), and the resin-modified glass-ionomer Vitrebond (VIT, Group 2). MATERIALS AND METHODS: Intact teeth with no cavity preparation were used as control Group (ICG, Group 3). Buccal Class V cavities were prepared in 34 sound human premolars. After exposing the pulps, the pulp capping materials were applied and the cavities were filled using Clearfil Liner Bond 2 bonding agent and Z100 resin-based composite. The teeth were extracted after 5, 30, and from 120 to 300 days, fixed in 10% buffered formalin solution, and prepared according to routine histological techniques. 6-microm sections were stained with hematoxylin and eosin, Masson's trichrome, or Brown & Brenn technique for bacterial observation. RESULTS: At 5 days, CH caused a large zone of coagulation necrosis. The mononuclear inflammatory reaction underneath the necrotic zone was slight to moderate. VIT caused a moderate to intense inflammatory pulp response with a large necrotic zone. A number of congested venules associated with plasma extravasation and neutrophilic infiltration was observed. Over time, only CH allowed pulp repair and complete dentin bridging around the pulp exposure site. VIT components displaced into the pulp tissue triggered a persistent inflammatory reaction which appeared to be associated with a lack of dentin bridge formation. After 30 days a few histological sections showed a number of bacteria on the lateral dentin walls. In these samples the pulp response was similar to those samples with no microleakage. VIT was more irritating to pulp tissue than CH, which allowed pulp repair associated with dentin bridge formation. These results suggested that VIT is not an appropriate dental material to be used in direct pulp capping for mechanically exposed human pulps.

Human pulpal response to direct pulp capping with an adhesive system.

PURPOSE: To evaluate clinically and microscopically the human pulp response when directly capped with an adhesive system or calcium hydroxide over short (9-12 days) and long (53-204 days) experimental periods. MATERIALS AND METHODS: Fifty-one sound human premolars scheduled for orthodontic extraction, had their pulp horns gently exposed with a diamond point. Debris in the pulp wound was washed out with a sterile saline solution. The pulps were then capped with either an adhesive system (Scotchbond Multi-Purpose Plus) or calcium hydroxide. All teeth were subsequently restored with resin-based composite (Z-100) according to the manufacturer's instructions. After the experimental periods, the teeth were extracted and processed for light microscopic examination. RESULTS: Short-term: the pulp tissue capped with SBMP-P exhibited dilated and congested blood vessels associated with a moderate inflammatory response and blanching of pulp cell nuclei. Long-term: no evidence of healing and bridge formation was observed. A persistent mild inflammatory pulp response was present. Micro-abscesses were detected in three cases associated with bacterial infiltration. Calcium hydroxide stimulated early pulp repair and dentin bridging which extended into the longest period.

Pulp response to direct capping with an adhesive system.

PURPOSE: To evaluate the pulp response following direct pulp capping with an adhesive system (Prime & Bond 2.0 - PB 2.0) and a zinc-oxide eugenol cement (ZOE) on pulp exposures in rat molar teeth. MATERIALS AND METHODS: Forty-eight Class I cavities were prepared on the occlusal surface of molar teeth of rats (Rattus Norvegicus, Holtzman). Pulp exposures performed on the cavity floor were capped either with the adhesive system P&B 2.0 or ZOE. After 7, 15, 30, and 60 days, the specimens were processed through H & E and Brown & Brenn staining techniques. RESULTS: Both pulp capping materials allowed pulp repair, characterized by reorganization of a new odontoblast cell layer underlying the dentin bridge formation. However, P&B 2.0 promoted a large zone of cell-rich fibrodentin matrix deposition between the pulp capping material and the dentin bridge, which was deposited far from the pulp exposure site. On the other hand, pulps capped with ZOE showed dentin bridging immediately subjacent to the pulp capping material. In those samples in which microleakage occurred between dental material and cavity walls there was a persistent inflammatory reaction and lack of complete pulp repair.

Luxation injuries and external root resorption--etiology, treatment, and prognosis.

When a tooth sustains a luxation injury, attachment damage of varying degrees will occur. In addition, necrosis of the pulp might result, thereby making the pulp space susceptible to infection. These circumstances can lead to root resorption. Treatment for root resorption includes preventing it by avoiding causes of root surface injury, minimizing initial inflammation, and reversing resorption.
