Root resorptions present a significant problem in endodontic therapy of the affected teeth and in dentistry in general. The objective of this study was to analyze, based on epidemiological and statistical research, the frequency of clinical incidence of pathological root resorptions in everyday practice related to localization, type of tooth, age and sex of patients. Radiographie documentation of patients treated from 1997 till 2002 at the Department of Conservative Dentistry and Endodontics, Faculty of Stomatology in Belgrade, was used as baseline for this study. Retroalveolar radiographs of teeth with visible signs of resorptions were singled out from 15654 patients' clinical records used for this study. The external resorptions were shown as radiolucent areas localized on various outer root surfaces, followed by significant or less significant resorption of lamina dura and alveolar bone. Out of all teeth analyzed in this study, 594 (3.79%) showed some kind of resorption. The ...

Introduction Our study aims to identify: the incidence of external root resorption (ERR) in current practice, the etiologic factors that could leading to ERR, the possible associations with other local and general factors, and also criteria indices upon that, teeth recovery with ERR is possible. Material and methods The study was performed in a lot with 264 patients, 153 women and 111 men, which were presented in 2010 at dental office in temporary or permanent teeth with incomplete root formed. Also, we selected all patients who required achieving at least one intraoral radiograph for complementary teeth diagnosis Results In our entire study group, mostly aged between 40-60 years, ERR percentage level was in males at 13% of cases and at 16% in women. The most affected teeth by ERR were molars (59%) and premolars (29%) and the most common etiological factors were by endodontic way (81%). In 10% of cases ERR involved more than one tooth or it was combined with internal root resorption...

The purpose of this study was to evaluate, radiographically, whether there is similarity in the apical root resorption found in endodontically treated teeth and untreated teeth when they are submitted to orthodontic treatment. From 2,500 treatment records examined, 16 patients were selected who had a maxillary central incisor treated endodontically before initiation of the orthodontic movement, and a vital homologous tooth (for control). Measurements were made by comparing the periapical radiographs taken before and after the orthodontic treatment. There was no statistically significant difference (p Ͼ 0.05) in apical root resorption found in the endodontically treated teeth compared to the group of vital teeth. (J Endod 2007;33:119 -122)

Objetive: This study aimed to evaluate the prevalence of internal and external resorption in periapical digital radiographs in permanent anterior teeth of patients attended in a private clinic of radiology in the city of Recife, Pernambuco, Brazil, in a period of three years. Study Design: A retrospective and observation study design was realized with the aim of observing an presence of events. A total of 4630 radiographs were analyzed from the archives of the clinic. Thus, it was observed the presence of internal and external root resorption and their location in in digital and digitalized periapical radiographs.Results: It was observed more external than internal resorption (99,65%) and the teeth most affected by dental resorptions were the upper incisors (11,8%). The apical and cervical thirds were also involved with the same frequency in internal resorption while the apical third was the most involved in external resorption. Conclusion: Digital radiograph has a important and es...

Introduction: External resorptions often occur as a lesion of inflammatory origin. The origin of the process begins on the side of the root cementum and goes towards the pulp of the tooth. The changes consist of the pathological loss of root cement, dentin, and bone surrounding the tooth. The dynamics of the process are enhanced by inflammatory or necrotic pulp changes. Aims: This study aimed to present contemporary views on the resorption of external tooth roots and the possibility of their treatment. Material and methods: The technique of observation and clinical and radiological diagnostics were used by the case-by-case method Result: Endodontic treatment was undertaken, consisting of chemo-mechanical preparation of the canal system and simultaneous obturation of the gutta percha canals with the AH + sealant and the BL thermal system. Conclusions: The applied treatment inhibited the progression of the resorption and led to the healing of periapical periodontitis.

BACKGROUND External apical root resorption (EARR) is one of the detrimental outcomes of an orthodontic treatment. The study was aimed to compare the mean EARR between endodontically treated and its contralateral vital tooth in adult orthodontic subjects. METHODS A total of 30 subjects were included in the study. EARR was evaluated on pretreatment and post-treatment orthopantomograms using Rogan Delft View Pro-X software. Equal number of endodontically treated and their contralateral vital teeth were evaluated. Linge and Linge method was used to evaluate the pretreatment and post-treatment root lengths. For comparison of EARR between genders, treatment type and vital versus endodontically treated teeth, Mann-Whitney U Test was applied. Spearman correlation was applied to determine the correlation of EARR with age of the patient, duration of treatment and pretreatment root length. A probability value of ≤0.05 was kept as statistically significant. RESULTS Vital teeth showed more root ...

The aim of this study was to determine the prevalence of apical root resorption in maxillary incisors during the initial stages of active orthodontic treatment and to test the hypothesis that root resorption increases with the progress of the treatment. The study sample consisted of 80 teeth of 20 patients (14 female, 6 male) with a mean age of 14.9±2.8 years. Root resorption was determined with standardized digitized periapical radiographs. All the periapical radiographs were obtained at the beginning of orthodontic treatment (T0) and 3 months (T1), 6 months (T2) and 9 months (T3) after the beginning of the treatment by a paralleling device. They were digitalized as 600 dpi with a flatbed scanner and analyzed by software for image analysis at 400x magnification utilizing a personal computer. All of the 4 maxillary incisors had an increasing amount of resorption during the 9-month period. The amount of root resorption between the time intervals was statistically significant (P<.0...

Background: Primary teeth are excellent model to figure out the differences in morphological and histological features of tooth resorption. They may be exfoliated due to physiological resorption of their roots or the coexistent physiological and pathological resorption that are usually observed in the replacement period of dentition. Aim: The aim of this study was to evaluate the qualitative differences in the appearance of the roots of primary teeth undergoing physiological or coexistent physiological and pathological root resorption. Material and Methods: Twenty primary teeth were examined, Ten exfoliated teeth with physiological resorption represented Group I and ten extracted teeth with coexistent physiological and pathological resorption represented Group II. Results: At light microscopic examination, group I showed deep round wave like resorption fossae filled with many odontoclasts, and the pulp showed inflammatory cell infiltration along with areas of dystrophic calcification. The odontoblasts were disorganized or disappear completely. Repair by cementum like tissue deposition was found internally. SEM examination revealed variable sized numerous resorption lacunae with smooth edges that had a circular or polygonal shape. Group II showed irregular resorbed root surface and various size odontoclasts besides thick granulation tissue. The pulp was degenerated, necrotic and contained calcification globules. The odontoblastic layer couldn't be identified. Cementum repair was evident externally but at the internal resorption surface. By SEM, the resorption fossae were smaller and irregular in shape with thinner edges. Conclusion: There were various morphological differences between physiological and coexistent physiological and pathological resorption of human primary teeth

criteria for root canai treatment of primary molars undergoing resorption. Endod Dent Traumatol 1995; 11: 136-141. © Munksgaard, 1995. Abstract -The endodontic anatomy of primary molars is difficult to predict because of thè balance of resorption and hard tissue deposition. In particular, thè resorption causes perforating lacunae across thè wall of thè root, even at thè furcation level, and modifies shape, dimension and position of endodontic apex. The phenomenon can be so deep as to compromise endodontic therapy. The first aim of thè study was to verify if reliable criteria can be found for treatability in primary molars undergoing resorption, i.e. if it is possible to predict if perforating lacunae are present or not. The second aim of thè study was to verify if other informations needed for endodontic treatment, as shape, dimension and location of thè apex, and curvature of thè root canai can be predicted. For thè study, 80 extracted primary molars, 75 of which pulpally involved by caries, were selected. The treatability was evaluated in term of root length, root shape, dimension and shape of endododntic apex, age of thè patient and Xray index of resorption. The association between variables was performed by multiple correspondence analysis. The results suggested that root length was thè most reliable criterion of thè integrity of thè root. The borderline of treatability was at thè length of 4 mm. The position of endodontic apex related to anatomical apex, and thè linguai related to thè buccal root length were analyzed by linear regression analysis. The canai length was often similar to thè root length (i.e. thè endo and anatomical apices were very dose) in lower and upper molars. However, in lower molars, if two or more canals were present in thè same root, a discrepancy was observed between buccal and linguai root length. This finding was Constant in first lower molars. In addition regression analysis provided a linear function between thè lengths of thè buccal and linguai side of thè same root in lower molars. Its coefficieiu b was 0.73.
Porcine parvovirus (PPV) 1 is a major causative pathogen of reproductive failure and PPV2–6 were recently identified as newly emerging viruses with unknown pathogeneses. In this study, we examined 926 samples from domestic pig farms for the presence of PPV1–6 coinfection. The prevalence of PPV1–6 was significantly greater in the lung tissue samples than in the aborted pig fetus samples. PPV3–6 were detected for the first time in Korean domestic pigs, and concurrent infections were more common than single infections in the pig population with numerous infectious pathogens such as PPV. Furthermore, the Korean PPV1 strain (PPV1-82) was identical to the virulent PPV-27a strain in this study. These results describe, for the first time, the prevalence of PPV1–6 in South Korean domestic pigs

What does it mean to be a healthcare chaplain? The recent introduction of the chaplaincy guidelines has taken chaplains into the heart of the healthcare system and ensured that the National Health Service in Scotland has to think about and perhaps re-think the role of chaplaincy and its place within the system of healthcare delivery within Scotland. This presents a challenge not only to the National Health Service but also to chaplaincy. Chaplains will be called to account for who they are and what they do in a way that they have not previously had to. The question of the professional identity of the chaplain is thus crucial. This paper reflects critically on the identity of chaplaincy as a healthcare discipline and offers some reflective comments on the pros and cons of what it might mean for chaplains to develop an identity as "healthcare professionals."
