Consistency across panels of ratings of appropriateness of dental care treatment procedures.

OBJECTIVE: To report on a study investigating the consistency across different consensus panels of ratings of appropriateness for dental procedures. RESEARCH DESIGN: The study conducted four consensus panels to determine, under various conditions, the appropriateness of five options for patients: no treatment; filling; crown; root canal with a filling or crown; extraction. The patients were categorised according to age; regular versus irregular use of dental care; degree of caries; degree of pain; degree of periodontal disease. PARTICIPANTS: The panellists were dentists enrolled in a continuing education programme on assessing the quality of dental care. The panellists were all individuals employed by various dental plans to evaluate the quality of care plans operating in California. RESULTS: The results indicate that the method does distinguish the dimensions of appropriateness used by the panellists in making their decisions, and that it is possible to substantially increase consensus among a diverse group of dentists and across separate panels on some procedures. However, it also showed that the process is sensitive to varying panels and that different variables had different outcomes in the ratings from the various panels. CONCLUSION: The consensus panel method holds some promise for determining the appropriateness of dental care. However the results of this study question whether it results in consistent ratings across different panels.

[Pulpal-periapical response to canal medication with Ca(OH)2].

This study consisted of biopsies of teeth and root tips removed after Ca(OH)2 therapy. The teeth were clinically intact or exposed to caries, trauma, and/or iatrogenesis. Following the therapy most of the canal walls were clean, but the canals contained varying amounts of pulp tissues, debris and Ca(OH)2 particles. In one case microrganisms were present in the apical part of the canal, but not beyond the foramen. The Ca(OH)2 therapy was efficient for its purpose.

Endodontic-orthodontic relationships: a review of integrated treatment planning challenges.

Literature review There is a paucity of information on the concise relationship between endodontics and orthodontics during treatment planning decisions. This relationship ranges from effects on the pulp from orthodontic treatment and the potential for resorption during tooth movement, to the clinical management of teeth requiring integrated endodontic and orthodontic treatment. This paper reviews the literature based on the definition of endodontics and the scope of endodontic practice as they relate to common orthodontic-endodontic treatment planning challenges. Literature data bases were accessed with a focus on orthodontic tooth movement and its impact on the viability of the dental pulp; its impact on root resorption in teeth with vital pulps and teeth with previous root canal treatment; the ability to move orthodontically teeth that were endodontically treated versus nonendodontically treated; the role of previous tooth trauma; the ability to move teeth orthodontically that have been subjected to endodontic surgery; the role of orthodontic treatment in the provision for and prognosis of endodontic treatment; and, the integrated role of orthodontics and endodontics in treatment planning tooth retention. Orthodontic tooth movement can cause degenerative and/or inflammatory responses in the dental pulp of teeth with completed apical formation. The impact of the tooth movement on the pulp is focused primarily on the neurovascular system, in which the release of specific neurotransmitters (neuropeptides) can influence both blood flow and cellular metabolism. The responses induced in these pulps may impact on the initiation and perpetuation of apical root remodelling or resorption during tooth movement. The incidence and severity of these changes may be influenced by previous or ongoing insults to the dental pulp, such as trauma or caries. Pulps in teeth with incomplete apical foramen, whilst not immune to adverse sequelae during tooth movement, have a reduced risk for these responses. Teeth with previous root canal treatment exhibit less propensity for apical root resorption during orthodontic tooth movement. Minimal resorptive/remodelling changes occur apically in teeth that are being moved orthodontically and that are well cleaned, shaped, and three-dimensionally obturated. This outcome would depend on the absence of coronal leakage or other avenues for bacterial ingress. A traumatized tooth can be moved orthodontically with minimal risk of resorption, provided the pulp has not been severely compromised (infected or necrotic). If there is evidence of pulpal demise, appropriate endodontic management is necessary prior to orthodontic treatment. If a previously traumatized tooth exhibits resorption, there is a greater chance that orthodontic tooth movement will enhance the resorptive process. If a tooth has been severely traumatized (intrusive luxation/avulsion) there may be a greater incidence of resorption with tooth movement. This can occur with or without previous endodontic treatment. Very little is known about the ability to move successfully teeth that have undergone periradicular surgical procedures. Likewise, little is known about the potential risks or sequelae involved in moving teeth that have had previous surgical intervention. Especially absent is the long-term prognosis of this type of treatment. During orthodontic tooth movement, the provision of endodontic treatment may be influenced by a number of factors, including but not limited to radiographic interpretation, accuracy of pulp testing, patient signs and symptoms, tooth isolation, access to the root canal, working length determination, and apical position of the canal obturation. Adjunctive orthodontic root extrusion and root separation are essential clinical procedures that will enhance the integrated treatment planning process of tooth retention in endodontic-orthodontic related cases.

Orthodontic extrusion: its use in restorative dentistry.

The technique described in this study demonstrates that the use of orthodontic extrusion can provide an alternative to extraction and extensive periodontal surgery. Selection of patients is an important aspect when considering this type of treatment. The crown-root ratio, as well as the root anatomy, if inadequate, may render this type of treatment inappropriate. The concept of a biologic width is discussed, and its application to forced eruption is described.

Dental caries.

Dental caries, otherwise known as tooth decay, is one of the most prevalent chronic diseases of people worldwide; individuals are susceptible to this disease throughout their lifetime. Dental caries forms through a complex interaction over time between acid-producing bacteria and fermentable carbohydrate, and many host factors including teeth and saliva. The disease develops in both the crowns and roots of teeth, and it can arise in early childhood as an aggressive tooth decay that affects the primary teeth of infants and toddlers. Risk for caries includes physical, biological, environmental, behavioural, and lifestyle-related factors such as high numbers of cariogenic bacteria, inadequate salivary flow, insufficient fluoride exposure, poor oral hygiene, inappropriate methods of feeding infants, and poverty. The approach to primary prevention should be based on common risk factors. Secondary prevention and treatment should focus on management of the caries process over time for individual patients, with a minimally invasive, tissue-preserving approach.

Reasons for and incidence of tooth mortality in a Swedish population.

Longitudinal studies on tooth mortality are rare but the reasons for tooth mortality have been studied by several authors. The aims of this investigation were to study the reasons for and incidence of tooth mortality in an earlier described Swedish population of 200 patients on two occasions with an interval of 5-7 years, and to see if the reasons for extractions were correlated to posts, crowns or endodontic status, respectively. 197 (4.0%) of the 4889 teeth registered at the first examination were lost during the interval. 65 (33%) of the lost teeth were endodontically treated. 44 (68%) of these were registered as having one or more root with a root-filling ending more than 2 mm from the apex and 29 (45%) were judged to have an improper seal. In 93 of the 197 lost teeth it was possible to find the reason for extraction from the patient chart. Based on distribution of selected variables, these 93 teeth seemed to be representative of the whole group of 197. It was concluded that tooth losses were evenly distributed in the different age-groups and that above all molars but also premolars were lost more often than teeth in the frontal region. Furthermore, endodontically treated teeth were lost more often than other teeth and the quality of the root-filling affected the risk for losses while crowned teeth did not run a higher risk of being lost than teeth without crowns. Finally, it was found that caries, including pulpitis and apical periodontitis, was the main reason for tooth extractions.

Antibodies in normal and diseased pulps reactive with microorganisms isolated from deep caries.

Immunoglobulin molecules in the supernatant fluids (SF) from pulpal explant cultures have been observed to react with microorganisms implicated in infections of root canals. In this study, the reactivity of immunoglobulin molecules in the SF from normal and irreversible pulpitis pulps to six strains of predominant microorganisms isolated from the immediate layer of carious lesions above the pulps used for explant cultures was investigated using an enzyme-linked immunosorbent assay. Two ATCC strains of Eubacterium were also included in this assay. Specific antibodies to Lactobacillus casei subsp. casei, Lactobacillus casei subsp. rhamnosus, Lactobacillus acidophilus (I), (II), Streptococcus mutans, Bacteroides intermedius, Eubacterium brachy, and Eubacterium alactolyticum in the SF from the normal and irreversible pulpitis tissues were observed with a large variation of antibody levels in both groups. Immunodiffusion assays of the SF revealed that IgG was the major class of immunoglobulin in the normal as well as the irreversible groups. The presence of natural antibodies in the normal pulps suggested a possible protective role of antibodies during the invasive process of caries.

Citric acid demineralization of cementum and dentin: the effect of the storage medium.

The purpose of this study was to see if the root surface topography of teeth, stored in saline and subsequently treated with citric acid, differred from the root surface topography of teeth that were treated immediately upon extraction, 12 freshly extracted adult human permanent teeth, with proximal surfaces free of caries and periodontal disease, were treated in succession. The crowns were removed at the level of periodontal attachment, the teeth sectioned buccal-lingually and a treatment area deligniated on each proximal section. The treatment area of 6 teeth was root planed to expose dentin (D) and scaled to remove adherent tissue and leave a cementum surfaces (C) on the other 6 teeth. A coronal-apical groove down the middle of the treatment area divided it into approximately equal parts or experimental regions. One proximal section of each tooth was placed in physiologic saline (S) and treated after 6 weeks of storage while the other proximal section was freshly treated (F). Treatment consisted of applying a 30% citric acid (CA) solution (pH = 1.60) for 5 min. Cotton pellets soaked in the citric acid solution were placed (P) on one half of the experimental area and heavily burnished (B) on the other half. Treatment areas were subsequently prepared for scanning electron microscopy analysis. Assessment was made of (i) the % of surface area tufted, (ii) fibril tufting depth (0.3) and (iii) fibril tufting density (1.3). Similarities were found in the data for both storage methods (F and S) across each application technique (P or B) and each tooth surface (D or C) with respect to the (i) % area tufted and (ii) frequency distribution of tufting depth scores. As for the application techniques, the data for burnishing was greater than placed across each storage method (F or S) and each tooth surface (D or C) for the same two parameters. The results of the study indicated that 6-week physiologic saline storage does not affect root surface demineralization by citric acid, as assessed by SEM.

Prevalence and technical standard of endodontic treatment in a Swedish population. A longitudinal study.

The aims of this thesis were to study longitudinally the tooth mortality, prevalence and technical standard of endodontic treatment as well as the endodontic treatment need in a Swedish population. Furthermore, the prevalences of teeth with crowns and posts were studied as well as the prevalence of apical periodontitis in such teeth, to see if these treatments affected the apical status. Finally, the reasons for and incidence of tooth mortality were investigated to see if the reasons for extractions were correlated to endodontic status, crown or post therapy, respectively. The interobserver variation between the two observers taking part in the investigation was also studied and found to be acceptable. The material consisted of full mouth radiographic surveys from 200 patients examined twice with an interval of 5-7 years. It was found that tooth losses were evenly distributed in the different age-groups and that molars were lost more often than teeth in the frontal region. Furthermore, endodontically treated teeth were lost more often than other teeth and the quality of the root filling affected the risk of tooth losses. Teeth with screw posts were lost more frequently than other teeth, while crowned teeth did not run a higher risk of being lost than teeth without crowns. Caries, including pulpitis and apical periodontitis, was the main reason for tooth extractions. There was a great need for endodontic treatment in the population examined, and the technical standard of the root fillings was poor. A slight improvement in quality of endodontic treatment was evident at the second examination. However, the technical standard was still poor. It is concluded that it is important that dentists in general practice should be better trained in performing endodontic treatment, and that research efforts should be made to find better and simpler methods for endodontic treatment.

[Treatment of gingival recessions of teeth with ceramic full crown by autogenous connective tissue graft].

PURPOSE: The aim of this clinical study was to evaluate gingival recession of teeth with ceramic full crown treated with subepithelial connective tissue grafts. METHODS: In 20 systemically healthy, whose ages ranging from 31 to 58 years, 32 teeth with ceramic full crown developed gingival recession. Selection of gingival recession defects was based upon the following criteria: A minimum of 2 mm of root surface exposure in coronal-apical height. Miller class I and II recession. Interproximal and labial probing depth </=4 mm. No active caries or restorations on the tooth surfaces. Gingival recession were treated with subepithelial connective tissue grafts technique. RESULTS: The results indicated that subepithelial connective tissue grafts increased the height of gingival recession (GR) and gingival thickness (GT), the mean percentage of root coverage (RC) was 85.1%. CONCLUSION: These results suggest that subepithelial connective tissue grafts were able to successfully treat gingival recession defects. Moreover, the results has significant clinical benefit for aesthetics and treatment outcomes.

Unusual case of bilateral talon cusp associated with dens invaginatus.

CASE REPORT: This paper presents a rare case of bilateral talon cusp in permanent maxillary central incisors, one on the labial and another on the lingual surface of each tooth. The condition was associated with dens invaginatus in a maxillary permanent lateral incisor, but no developmental syndrome was identified. The left central incisor required no treatment because the aesthetic appearance was satisfactory and neither occlusal interferences nor caries were present. After careful investigation of the right lateral incisor, a sealant was applied. Root canal treatment was indicated for the right central incisor that had a wide open apex with thin, weak, divergent walls, and an apical radiolucency.
