Cbct Analysis

The aim of this study was to compare the alveolar bone crest (ABC) level of root canal filled (RCF) teeth without apical periodontitis with corresponding non-filled teeth in the same individual using three-dimensionally cone-beam computed tomography (CBCT) data. Two hundred and thirty-five matching pairs of RCF teeth and corresponding teeth without RCF were selected from a pool of 580 random CBCT-images (voxel size 160–200 µm). Teeth with apical periodontitis, perio-endodontic lesions or surgical endodontic treatment were excluded. The distance between the cemento–enamel-junction (CEJ) and the ABC was assessed centrally mesial, distal, palatal/lingual and buccal at each tooth (∑1880 measuring points) in a standardized manner. Topographic, gender, and age-related relationships were also noted. Data were analyzed using the Kruskal–Wallis-test. The ABC-level between RCF teeth (2.64 ± 1.25 mm) and teeth without RCF (2.61 ± 1.16 mm) did not differ significantly (p > 0.05). No differences concerning localization (maxilla/mandible, tooth type) and gender (p > 0.05) occurred. Overall, ABC-level in the maxilla (2.74 ± 1.48 mm) was significantly lower (p < 0.001) compared to mandibular teeth (2.50 ± 1.41 mm). Patients >41 years had significantly lower ABC-levels than younger patients (p < 0.05). Men showed a reduced bone level compared to women (p < 0.05). In conclusion, RCF teeth are identical to their non-RCF counterparts, at least in terms of crestal bone level, regardless of the location or type of tooth and the gender of the patient. Thus, root canal treatment is an essential pillar for long-term tooth preservation.

This cross-sectional study aimed to determine the degree of visibility of maxillary and mandibular anterior teeth at rest in different age groups and to evaluate the smile line, smile arc, and number of maxillary teeth displayed during smiling among the Saudi population visiting King Abdulaziz University Dental Hospital, Jeddah, Saudi Arabia. A total of 157 participants (77 males and 80 females) were included in this study with an age range of 19 to 69 years. All participants had maxillary and mandibular anterior teeth without restorations. Crown length and visible portions of anterior teeth at rest were measured using a Fowler Electronic Digital Caliper. Three measurements of each variable were recorded by two independent dental interns and calibrating their measurements was performed. Smile line, smile arc, and number of teeth displayed during smiling were examined. The collected data were statistically analyzed using SPSS software. It was found that the average clinical crown lengths in the maxillary lateral incisor, mandibular central incisor, and canine were significantly higher in males than females. At rest position, females displayed more maxillary central and lateral incisors. The displayed length of maxillary teeth at rest is inversely proportional to increasing age; the reverse occurs in mandibular teeth. The common visibility of maxillary teeth during smiling was from the second bicuspid to its counterpart. Average smile line and consonant smile arc were the most common characteristics. It was concluded that both age and gender affect the characteristics of tooth display at rest and in smiling. These effects should be considered during treatment planning and restoration of anterior teeth to obtain a more predictable esthetic outcome.

Abstract Background The present study aimed at investigating the prevalence of Apical periodontitis in a Moroccan Adult subpopulation with a non-surgical root canal treatment and to assess associated risk factors including endodontic treatment quality, periodontal health status, coronal restoration cavity design and quality. Methods A total of 358 endodontically treated teeth were evaluated after more than 1-year period in a Moroccan subpopulation according to predetermined criteria. Studied parameters were assessed clinically and radiographically. The association between coronal restoration quality, cavity design, periodontal status, root canal filling quality, coronal restoration related features, presence or absence of the opposing dentition and the periapical status was determined. Data were analyzed using chi-square test, odds ratio and logistic regression. Results The present study revealed that gingival health, coronal restoration with CL II cavity design, and root canal filling quality influenced periapical status of endodontically treated teeth. Multivariate analysis showed that this association was statistically significant for gingival inflammation (95% CI 1.08–3.91, OR 2.05, p = 0.02), inadequate coronal restoration (95% CI 1.16–4.04, OR 2.16, p = 0.01), inadequate root canal filling length and homogeneity (95% CI 1.24–3.01, OR 1.93, P = 0.004), (95% CI 1.41–4.44, OR 2.50, p = 0.002) respectively. Conclusions The present study revealed that inadequate coronal restorations especially with large proximal margins (CL II cavity design) and gingival inflammation increased the risk of apical periodontitis in endodontically treated teeth. Prevalence of Apical periodontitis in the present study was 72.1%.

Background. This study aimed to assess the prevalence of missed canals in endodontically treated teeth and their association with apical periodontitis in a Saudi Arabian population using CBCT. Materials and Methods. A total of 208 CBCT radiographs were investigated. For each tooth, radiographs of axial, coronal, and sagittal segments were acquired to appraise the external as well as the internal structure of the root canal system and apical area. In root canal-treated teeth, unfilled canals appearing from the cementoenamel junction to the apex were defined as missed untreated canals; and a periapical lesion was considered when disruption of the lamina dura was detected, and the low-density area associated with the radiographic apex was at least twice the width of the periodontal ligament space. The data were presented as frequencies and percentages. The Z-test was used to analyze the differences in proportions with the significance level set at P value <0.05. Results. The overall prevalence of missed canals among endodontically treated teeth was 18%. The prevalence of missed canals was higher in maxillary first molars with 40.6%. The overall prevalence of apical periodontitis among teeth with missed canals was 90%. It was 84.2% in the maxilla and 100% in the mandible. The second mesiobuccal canal in the maxillary first molars and mesiobuccal and distobuccal canals in mandibular teeth were the most missed canals. Conclusion. Apical periodontitis in root canal-treated teeth with missed canals was high (90%), with most identified missed canals in maxillary and mandibular first molars.

Objective: The aim of this study was to examine the quality of root canal fillings and their relationship with apical periodontitis (AP) in a selected Turkish population. Material and Methods: The cases in this study was formed of patients attending routine dental treatment at the Faculty of Dentistry, University of Birun. 1024 patients were examined with panoramic radiographs and 1780 endodontically treated teeth with present periapical radiographs. Endodontic treatment quality was evaluated by obturation length, density, taper quality and iatrogenic errors. Presence of AP was analysed according to Ørstavik’s periapical index (PAI). The chi-square test was used for statistical analyses. Results: Statistically significant relationship was found between both the tooth type and location with obturation quality (p: 0.000; p < 0.05). Obturation quality of maxillary and mandibular molars are significantly less than the other tooth types in the same location. Apical periodontitis were noticed in 740 teeth (41.6%). Inadequate obturation quality was found to be significantly effective on the periapical status of tooth types both in maxilla and mandible (p < 0.05). Conclusion: The frequency of inadequate root canal obturations of endodontically treated teeth of the selected Turkish population was high, especially in molar teeth and women. Even though radiographic obturation quality is not the only success criteria in endodontic treatment, it is still one of the most important criteria regarding the positive correlation of “inadequate” obturations with AP.KEYWORDSPeriapical periodontitis; Radiography; Root canal obturation; Root canal theraphy.

The present study was conducted to examine the developmental patterning of food preferences in a large sample of British schoolchildren and to investigate possible gender differences. Using a cross-sectional survey design, the study was carried out in three primary and three secondary schools in West London, UK. A total of 1291 children aged from 4 to 16 years completed a 115-item food preference questionnaire in class time, supervised by class teachers and assistants. Children indicated whether they had ever tried each item and, if so, how much they liked it. We observed age-related increases in the number of foods tried (P<0·001), liked (P<0·005) and disliked (P<0·05). Controlling for the number of foods tried rendered the increase in dislikes non-significant and reversed the age effect on the number liked. Girls liked fruit (P<0·05) and vegetables (P<0·001) more than boys did; boys liked fatty and sugary foods (P<0·005), meat (P<0·001), processed meat products (P<0·001) and eggs (P<0·05) more than girls did. Some age differences were apparent in liking for categories of food, although the effects were not linear. Across ages and genders, children rated fatty and sugary foods most highly, although ratings for fruit were also high. Children's food preferences overall are not consistent with a healthy diet. Interventions should focus on increasing the familiarity, availability and accessibility of healthy foods and should be mindful of the need to target messages appropriately for boys who have less healthful food preferences than girls at all ages.

An analysis of the literature was the basis for a set of predictions regarding the Preschool Embedded Figures Test performance of a small, cross-sectional sample of 37 3- to 5-year-old children. The test scores were modestly reliable. Predicted age-related differences in scores for boys and girls were observed, including an interaction of age with gender; however, other predictions regarding those scores were not supported. Based on a small sample, it was tentatively concluded that the evidence for continued use of the Preschool Embedded Figures Test as a measure of field independence for young children was weak.
