This paper represents a part of research plan of “Advanced Endodontic Technology Development.” In order to aid endodontic treatment a 3-D computer model of root canals has been created which shows the geometrical characteristics. The extent of work needed for root canal treatment is obtained from this 3-D model. The objective of this paper is to convert the geometrical characteristics into automatic treatment procedure planning. This computer-aided process planning for endodontic treatment determines tool selection and process method. It also calculates tool path and optimum tool movement distance. The output of this planning system is a numerical controlled program. Because of paper size limitation, only tool selection and path control during coronal canal treatment preparation for posterior teeth are discussed in the paper. The computer-aided treatment procedure planning system provides transformation from a 3-D canal model to a machine-controlled program that will yield a treated root canal ready for filling. It serves as a bridge between design (3-D canal model) and manufacturing (canal treatment). Unlike conventional methods for root canal treatment, the computer-aided treatment process planning system emphasizes a non-destructive internal tooth geometry examination and less invasive access preparation.

Abstract Purpose This retrospective study evaluated the clinical and radiographic status of nonsurgical endodontic treatment (ET) of anterior and posterior teeth in HIV-seropositive patients. Methods ET was analyzed in 26 anterior and 34 posterior teeth from 54 consecutive HIV patients (gender ratio 3 Male : 1 Female, mean age 40.2 years, mean CD4 240, CD4<500 in 88%, 12 with AIDS) over a six year period with a minimum of six months follow-up. ET was evaluated as successful, questionable, or failure based upon clinical factors (palpation, mobility, sinus tract, percussion, function, infection/swelling, occlusion, symptoms) and radiographic factors (periodontal ligament space, rarefaction, lamina dura, root resorption, obturation) during post-treatment examinations with a mean follow up of 26 months. Results Clinical evaluation at follow up found ET outcome was successful in 88%, questionable in 10% (tenderness with percussion, mobility, widened ligament), and a failure in 2% (developed lesion after ET). Periapical lesions were present in 37% of cases (mean lesion size 6.2 mm). Following ET, mean lesion size (1.8 mm) had decreased by 71%. Obturation was evaluated as optimal or acceptable in 68%. Radiographic evaluation was considered successful in 80%, no change in 15%, and a failure in 5%. Conclusions Despite obturation deficiencies and the immunocompromised state of the patients, endodontic therapy has a relatively high degree of success in the majority of HIV/AIDS patients. HIV infection and AIDS should not be considered as a contraindication to endodontic therapy in this patient population. Citation Suchina JA, Levine D, Flaitz CM, Nichols CM, Hicks MJ.

Introduction: Studies on the prevalence of apical periodontitis and endodontic treatment in Portugal are scarce and outdated. However, studies in other countries have shown that the prevalence of apical periodontitis is high, especially in endodontic treated teeth. Objective: To estimate the prevalence of root-filled teeth and apical periodontitis in an adult Portuguese population. Materials and methods: Panoramic radiographs of a random sample of 222 subjects over 18 years old, who had more than seven teeth, and went to the Faculty of Dentistry, University of Porto, for the first time in 2010, were examined. The number of teeth that were root-filled and the periapical status of all teeth were assessed. Results: Apical periodontitis (PAI ≥ 3) was found in 1.7% of all teeth in the population study. Out of 5.552 teeth, 215 (3.9%) had filled roots. The prevalence of apical periodontitis was greater for root-filled teeth, posterior teeth, and men. The prevalence of apical periodontitis is also increased with age. Conclusion: The prevalence of apical periodontitis in Portugal is similar to its prevalence in other European countries and is higher for root-filled teeth than for non-treated teeth. The prevalence of root-filled teeth is different for Portugal than for other countries, which may be due to the differences in healthcare services provided in various countries.

Endodontic treatment is accompanied by the loss of a significant amount of tooth crowns, which leads to a significant decrease in their strength characteristics. The restoration of endodontically treated teeth, as a rule, is carried out by the direct method, however, a unified approach regarding direct or indirect restoration has not yet been determined. The aim – retrospective analysis of the clinical condition of direct restorations of endodontically treated teeth. Materials and methods. 284 patients aged 25 to 60 years were examined; they studied the state of 888 previously performed direct restorations of the anterior and posterior teeth after endodontic treatment in a period of 2 to 10 years. Restorations were evaluated according to the adapted clinical criteria “integrity of the restoration”, “marginal fit of the material”, “marginal staining”, “anatomical shape”, “colour correspondence for the restoration”, “roughness of the surface of the material”, as well as the criterion “condition of the contact point” for located on the contact surfaces of the teeth of the restorations. Results. Of the 888 examined direct restorations, 760 restorations (85.6±1.18 %) were located in the posterior teeth, with 562 restorations in the molars (63.3±1.62 % of the total) and 198 in the premolars (22 , 3±1.40 %), and 128 restorations (14.4±1.18 %) were detected in the anterior teeth, while in the incisors - 80 restorations (9.0±0.96 %), in the fangs – 48 (3.5±0.76 %). 720 restorations (81.1±1.31 %) were made from photocomposite materials, 97 restorations (10.9±1.05 %) from chemical curing composites, 71 (8.0±0.91 %) from glass-ionomer cements . The most common violations were colour mismatch – in 511 restorations (57.5±1.66 %), marginal staining - in 470 restorations (52.9±1.68 %), surface roughness - in 357 restorations (40.2±1.0, 65 %). More often than others, in the reconstructions of their photocomposites and glass ionomers there was a colour mismatch, and surface roughness for chemical composites. Conclusions. For direct tooth restoration after endodontic treatment in 81.1±1.31 % of cases, photocomposite materials are used, less often chemical curing composites and glass ionomers. Of the violations of such restorations, the most frequent are colour mismatch, surface roughness and edge staining.

The aim of the present report was to describe a case of direct composite resin restoration in tooth 46, with emphasis on the importance of polishing. A 21-year-old female patient dissatisfied with the aesthetic amalgam restoration of her tooth 46 came to the our institution for correction of the situation. The procedure performed consisted of registration of occlusal contacts, selection of resin color, removal of amalgam restoration, coronal reconstruction with composite resin, occlusal adjustment, finishing and polishing, with the use of atomic force microscopy of the resin before and after polishing. A correct clinical protocol for the posterior composite resins is fundamental for the optimization of aesthetic results, for clinical performance and for consequent restorative longevity. The atomic force microscopy images of the resin used before and after polishing emphasize the necessity and clinical importance of this operative step.Descriptors: Dental Materials; Dental Restoration, Permanent; Dental Polishing; Microscopy.ReferencesFrese C, Staehle HJ, Wolff D.

ABSTRACT Aims and objectives The objective of the study is to assess the outcome of lengthy root canal sessions (more than 2 hours) on temporomandibular joint (TMJ) and its associated structures. Materials and methods Totally, 250 patients who had undergone root canal treatment that lasted for more than 2 hours were examined for the status of TMJ and masticatory muscles. The second part of the examination was performed after 1 week to check for any pain and tenderness. Data were analyzed using Statistical Package for the Social Sciences (SPSS). Results Results showed that patients of older age suffered from more pain postoperatively. Similarly, women experienced more pain than males. Those patients who were treated for their posterior teeth complained of more pain than those treated for anterior teeth. Conclusion Prolonged root canal sessions result in longer and wider opening of mouth for longer period of time, thus causing harm to TMJ and associated masticatory structures and may give rise to sign and symptoms of temporomandibular disorder (TMD). Clinical significance It is prudent to break treatment sessions into shorter appointments and let patients relax during the treatment to prevent any extra stress on the TMJ and associated masticatory apparatus.
