The aim of this study was to determine the frequency of endodontic treatment in an adult Ukrainian population in relation to the age and its distribution depending on the type of the teeth. Materials and methods: A total of 435 digital panoramic radiographs of adults (aged 18 to 72 years) were examined. A tooth was qualified as root filled (endodontically treated), if radiopaque root-filling material was determined in the pulp chamber and/or in the root canals. Pearson’s chi-squared test (χ2) and Spearman’s rank correlation were applied for data analysis. Results: It was revealed that 82.5% of patients had previously received endodontic treatment of the teeth. The overall percentage of root filled teeth in adult dentition is 12.08%. The analysis of the rate of endodontically treated teeth in different age groups identified an increasing of treated teeth with age – from 5.2% in the youngest cohort (18-19 years old) to 24.9% in the oldest cohorts. It was revealed that 822 teeth (14.2%) on maxilla and 569 (9.9%) on the mandible were endodontically treated. Most often root filled teeth were first mandibular molars (39.3%), first maxillary molars (26.7%) and second maxillary premolars (20.4%). Much lower rate of endodontic treatment were considered in lower mandibular incisors and canines (0.7%, 0.9% and 1.5% respectively). Conclusions: A total of 82.5% examined adults had one or more endodontically treated teeth in this study. The obtained results prove the necessity of prevention of caries with special emphasis on the first maxillary and mandibular molars, and maxillary second premolars, which have significantly higher frequency of root canal treatment in comparison to other teeth groups.

The success of endodontic treatment depends on many factors. The most important of them are the knowledge and manual skills of the dentist.Materials and methods. We analyzed the condition of teeth after endodontic treatment in 300 patients aged 20 to 70 years. Were studied 300 images of CBCT, the number of treated teeth and the number of cases of unsuccessful endodontic treatment was analyzed.Results. According to CBCT data, high-quality obturation of the root canal system was observed in 1335 (75%) endodontically treated teeth. The reasons for successful endodontic treatment are under-sealing of the root canal (16%), removal of material beyond the apex (5.6%), and missed root canals (3.4%).Conclusion. Clinical dental patient examination revealed that maxillary and mandibular molars most often undergo endodontic treatment.

Microbiological Status

Summary Introduction The main objective of endodontic treatment is to eliminate infection from root canal and prevent reinfection by three-dimensional hermetic obturation of the canal system. Endodontic failure can occur due to inability of complete control and elimination of infection from the root canal. The aim of this study is to investigate, by PCR technique, microbiological status of previously endodontically unsuccessfully treated teeth immediately after the removal of obturation material. Material and Methods The analysis included 30 teeth indicated for endodontic retreatment. After removing previous root canal filling material, the bacteriological sample was taken by sterile instrument (# 15) and paper points. Standard PCR technique was used to analyze the incidence of E.faecalis, P.micros, P.intermedia, P. endodontalis and A.actinomycetemcomitans. Results Positive bacteriological findings were registered in 80% of cases, while bacteria were not identified in 20% of all samples (all taken from the root canals without significant changes in periapical tissue). From 24 canals with identified bacteria, 17 had affected apical periodontium. The most dominant microbe in root canals with positive bacteriological finding was E.faecalis (83.3% of the canals) and P.intermedia (75%). In case of teeth with chronic periapical changes, the most common was E. faecalis (94%) and P.intermedia (82.3%). Conclusion The presence of periapical lesions significantly affects microbiological status of endodontically treated teeth. The presence of bacteria was confirmed in most teeth with periapical lesions, while the most frequently identified bacteria were E. faecalis, P.intermedia and P.micros.

Endodontic Retreatment

Introduction: In endodontically treated teeth, dentinal defects such as microcracks can progress to a vertical root fracture and lead to tooth loss. Objective: The present study aimed to evaluate, by micro-computed tomography analysis, the formation of dentinal microcracks during filling removal in endodontic retreatment of root canals filled with gutta-percha and Total Fill BC bioceramic sealer. Methods: Twenty mesial roots of mandibular molars were instrumented and obturated with gutta-percha and Total Fill BC sealer and then the filling material was removed with rotary Protaper Retreatment files. The specimens were scanned before instrumentation, after filling and after retreatment. The transversal images obtained after filling were compared with the images obtained after removal of the filling material. A descriptive statistical analysis was performed. Results: Among the 24.444 cross-sections analyzed, 5.67% presented some type of dentinal defect, with 0.51% in the initial images, 2.58% in the post-filling images and 2.58% in the post-retreatment images. All the dentinal defects identified in the images obtained after the retreatment were already present in the corresponding images after the filling. New dentinal microcracks were not observed after removal of the filling material. Conclusion: Retreatment of mesial roots of mandibular molars filled with a silicate-based root canal filling material do not influence the formation of dentinal microcracks.

AbstractPurpose:To investigate the relationship between age and Advanced Life Support (ALS) utilization.Population:All patients from 1 January 1987 to 31 December 1988 transported by ALS ambulances within Lebanon County, a rural/urban county of 112,000.Methods:All runs resulting in patient treatment by ALS personnel were tallied at five-year age intervals and sub-grouped by trauma- and non-trauma-related calls. Utilization rates for each age group were obtained by dividing the calls by the population of each group. Correlation with age was tested by Spearman's rank correlation. Treatment rates for age groups were calculated for the six most frequent medical etiologies. To illustrate the effect of age distributions, age rates were applied to projected state and national population distributions.Results:There was a significant correlation with age for all transports (p < .01; r=.93) and for those not related to trauma (p<.01; r=.98). Correlation was not detected for trauma-related responses (p>.10; r=.19). Non-trauma-related case incidence varied among age groups, ranging from 1.1/1,000 for age five through nine years to 89/1,000 for age 80–84 years. Congestive heart failure, cardiac ischemia, syncope, myocardial infarction, and cardiac arrest evidenced increased incidence with age. Seizure did not. Older populations had a higher projected utilization of ALS services than did the younger age groups.Conclusion:Non-trauma ALS utilization is highly dependent on the age of the patient. Due to projected aging of the population and increased utilization of ALS by the elderly, projected utilization will increase at a rate faster than will the population. Age:rate data can be combined with population projections to estimate future need.

ABSTRACT Objectives: The objective of this study is to evaluate the frequency and distribution of early tooth loss and endodontic treatment needs of permanent first molars in a Turkish pediatric population. Materials and Methods: A total of 7,895 panoramic radiographs taken for routine dental examination at the Department of Oral Maxillofacial Radiology between 2008 and 2012 years were investigated. Two independent specialists evaluated early tooth loss and endodontic treatment needs of permanent first molars using panoramic radiography and patient anamnesis forms. The teeth were classified according to the following data: (a) Missing teeth, (b) teeth requiring extraction, (c) endodontically treated teeth (ETT), (d) teeth requiring endodontic therapy. The data also classified according to four factors: Age group (6-12 and 13-16), gender (boy and girl), jaw (mandible and maxilla) and side (right and left). A Chi-square test was used for statistical analyses. Results: A total of 19,488 and 12,092 teeth were evaluated in the child group and adolescent group respectively. All data were higher in adolescents than children (p < 0.001). For gender factor, only ETT was higher in girls than it was in boys (p < 0.001). For the jaw factor, all data were higher (p < 0.001) in mandible than in the maxilla. For the side factor, no statistical difference existed between right and left. Conclusions: Early tooth loss and endodontic treatment needs of permanent first molars showed variability according to age groups and jaws. When the results were compared according to the side and gender factors, no statistical difference was found (p > 0.05) except with the data of ETT in gender groups.

ABSTRACT Objective: This study was designed to investigate radiographically the effects of age and external irritating stimuli on the morphology and thickness of the pulp chamber ceiling and floor in mandibular molars. Materials and Methods: A total of 234 panoramic radiographs were recruited and 494 mandibular molars were examined in this study. The sample was divided into six age groups: Group 1, <20 years; Group 2, 20-29 years; Group 3, 30-39 years; Group 4, 40-49 years; Group 5, 50-59 years and Group 6, >60 years. Each group was subdivided into two subgroups with regard to the tooth condition (intact or non-intact teeth). Four distances, two angles and two ratios were measured, in order to estimate the dimensions of the pulp chamber and the thickness of the pulp chamber ceiling and floor. Results: The thickness of the pulp chamber ceiling and floor increased significantly from Group 1 to 6. The pulp chamber floor angle presented progressive sharpness from Group 1 to 6 whereas the pulp chamber ceiling angle presented progressive bluntness from Group 1 to 5 and sharpness from Group 5 to 6. Significant differences were identified in the thickness of the pulp chamber ceiling, the thickness of the pulp chamber floor and the ceiling-floor distance between intact and non-intact teeth. Conclusion: Based on those results, there are differences in the location of secondary dentin formation between the two pulp chamber walls. Age is related to diminished pulp chamber size. The increase rate of the pulp chamber ceiling thickness is similar to that of the pulp chamber floor thickness. Furthermore, external irritating stimuli have an effect on the pulp chamber dimensional changes.

Introduction: The study of endodontic epidemiology may help in prediction of future needs for dental treatment in a dentate population. The prevalence of endodontically treated teeth in the Malaysian population has never been investigated and their estimates have been based on studies from other countries. This study evaluated the prevalence of endodontically treated teeth in an adult Malaysian population attending a dental school clinic in northern Malaysia. Methods: The sample of this cross-sectional study examined the orthopantograms of 1663 patients in age group 18 to 75 years old, visiting the clinics of AIMST dental institute. A total of 33462 teeth were examined by four calibrated professionals. Any radiographic evidence of presence of radio-opaque material in pulp space was considered as endodontic treatment for the particular tooth. Third molars, supernumerary teeth and faulty radiographs were excluded from the study. Data was recorded with respect to gender, age and ethnicity of the patient and also the type of tooth. It was statistically analysed using Odds ratio, logistic regression and chi-square test. Results: There was a greater prevalence of endodontic treatment in females than males and 31 to 40 years age group. Malay population had higher number of cases of overall endodontically treated teeth, while Indian population showed highest percentage of cases within any ethnic group. Maxillary molars and mandibular molars were most frequently treated teeth, whereas canines showed the lowest prevalence. Findings were more significantly higher for maxillary teeth than mandibular teeth and for left side than right side. Conclusion: The prevalence of endodontically treated teeth in the Malaysian adult population was higher than that observed in epidemiological studies from other countries. This might is considered due to the higher incidence of caries and awareness emerging among the sub-population for preserving natural teeth. The results also concluded the necessity of more educational programs in Endodontics.

ABSTRACT Introduction A thorough knowledge of the anatomic morphology of the root canal system is necessary for the long-term success of the root canal therapy. The occurrence of C-shaped root canal configuration is one such variation. Achievement of favorable prognosis after commencing root canal therapy in such teeth is one of the challenges imposed on the endodontist. Hence, we evaluated the healing occurring after endodontic therapy in patients with C-shaped root canals in mandibular molars. Materials and methods The present study was conducted in the Department of Conservative Dentistry of the institution and included assessment of all the patients who underwent root canal treatment of the mandibular first and second molars. Endodontic therapy was performed in all the cases by experienced endodontist. Final postoperative radiographs were taken. Recording of the data of the personal and clinical details of a total of 250 patients was done. All the clinical and radiographic details of the patients, such as tooth location in the jaw, presence or absence of C-shaped canals, status of the pulp tissue, presence or absence of the fractures, and other details of the patients were recorded. Radiographic and clinical examination of the tooth of the patients was done during the baseline visit and further during the follow-up visits. The presence of C-shaped root canals was confirmed using the radiographs. Periapical index (PI) scoring system was used. Categories defined for enlisting the healing after the root canal treatment with the assessment of the PI score. All the results were analyzed by Statistical Package for the Social Sciences software. Results Vital pulp tissue was encountered in majority of the cases. C-shaped root canal configuration was observed in 40% of the cases included in the present study. After completion of the endodontic therapy, complete crown placement was done in only 22% of the cases. In cases of vital teeth with C-shaped root canals configuration, most of the teeth showed complete healing. Significant results were obtained while comparing the complete coverage crown parameter in relation to the healing process in teeth with C-shaped root canals. Conclusion In the present study, no significant effect of the C-shaped root canal configuration was found on the healing rate of the endodontic therapy in mandibular molars. Clinical significance Meticulous endodontic therapy with special techniques should be done while preparing teeth with C-shaped root canals.

Mandibular molars demonstrate considerable variations with respect to number of roots and root canals. The possibility of additional root canals should be considered even in teeth with a low frequency of abnormal root canal anatomy. This paper discusses the endodontic management of the rare anatomical complexity middle mesial canals in mandibular first molar and also serves to remind the clinicians that such anatomical variations should be taken into account during the endodontic treatment of the mandibular molars.

Timely und quality restauration of endodontically treated teeth is one of the major conditions for success of endodontic therapy. The aim of this study was to determine the efficiency of individual post cemented in endodontically treated teeth using radiographie parameters. 142 endodontically treated teeth restored with individual posts and permanent prosthetic restaurations were included in the clinical and radiographie research. The results of radiographie analysis reveled correctly made and cemented posts in 64% of the cases, inadequately placed posts in 14,4% and inadequate obturation between the tip of the post and radiographie apex, in 19,9% of the case. As a conclusion, correct course of endodontic treatment, clinicians knowing of anatomomorphological characteristics of root canals, correct gutta-percha removal and clinicians adaptibility to a specific case, are essential for the correct restauration of endodonticaly treated teeth with individual posts.
