Dentin Formation

Dentinogenesis imperfecta is the one of most common hereditary disorder of dentin formation, especially at histodifferentiation stage. It reported have to an incidences of 1 in 8000. Dentinogenesis imperfecta is an autosomal dominant, affecting both the formation and mineralizatin of dentin. CASE: A 20-year-old female patient came to integrasi A RSGMP UNSOED with crown fracture of anterior teeth 11, after eating a solid food. A permanent filling was conducted on 21 with the same cause one year ago. Intraoral examination showed attrition, yellowish and translucent on both maxillary and mandibullary teeths. Radiography showed that obliterated pulp chamber and shrinked root canal. Porcelain fused to metal crown was planned for this case. Conclusion: Dentinogenesis imperfecta is a hereditary disorder of tooth development. It caused the teeth to be discoloured (blue-grey or yellow-brown color), and fragile. Treatment planning for patient with dentinogenesis imperfecta is restorative treatment that can be apply to deciduous or permanent teeth, because exposed dentin will increase the risk of caries and infection.

Tooth Buds

Dental fusion also called ‘synodontia’ is a rare dental developmental anomaly in which the union of two independently developing primary or permanent tooth buds occurs. Tooth fusion is defined as union between the dentin and / or enamel of two or more separate developing teeth. The fusion may be partial or total depending upon the stage of tooth development at the time of union. The etiology of fusion is still unclear. The overall prevalence of the tooth fusion is approximately 0.5%. Fusion may be unilateral or bilateral and most often occurs in primary teeth with more predilections for anterior teeth. Clinically fused anterior teeth frequently have a groove or notch on the incisal edge that goes in buccolingual direction and radiographically, the dentin of fused teeth always appears to be joined in some region with separate pulp chambers and canals. Hence the cases of fusion of permanent teeth in different ages are presented.Bangladesh Journal of Dental Research and Education Vol.5(2) 2015: 70-72

Purpose This study aimed to validate the Willems Belgian Caucasian (Willems BC) age estimation model in a Kenyan sample, to develop and validate a Kenyan-specific (Willems KB) age estimation model and to compare the age prediction performances of both models. Methods Panoramic radiographs of 1038 (523 female, 515 male) Kenyan children without missing permanent teeth and without all permanent teeth fully developed (except third molars) were retrospectively selected. Tooth development of the seven lower-left permanent teeth was staged according to Demirjian et al. The Willems BC model, performed on a Belgian Caucasian sample and a constructed Kenyan-specific model (Willems KB) were validated on the Kenyan sample. Their age prediction performances were quantified and compared using the mean error (ME), mean absolute error (MAE) and root-mean-square error (RMSE). Results The ME with Willems BC method equalled zero. Hence, there was no systematic under- or overestimation of the age. For males and females separately, the ME with Willems BC was significantly different from zero, but negligible in magnitude (–0.04 and 0.04, respectively). Willems KB was found not to outperform Willems BC, since the MAE and RMSE were comparable (0.98 vs 0.97 and 1.31 vs 1.29, respectively). Although Willems BC resulted in a higher percentage of subjects with predicted age within a one-year difference of the true age (63.3% vs 60.4%, p=0.018), this cannot be considered as clinically relevant. Conclusion There is no reason to use a country-specific (Willems KB) model in children from Kenya instead of the original Willems (BC) model.

Introduction: the esthetic factor should be considered for every patient who seeks a comprehensive dental treatment, especially for women. The anterior teeth deformities will diminish the levels of confidence and decrease self-esteem of the patients. The tooth development disturbances, such as enamel hypoplasia, may present an esthetic problem. Enamel hypoplasia is an alteration of organic matrix formation which characterized by the defect or porosity on the enamel surface. It can be restored with a variety of restorative treatment options including indirect porcelain veneers. Case: a 30 years old female patient was referred with chief complaint of anterior teeth discoloration. Clinical examination on the maxillary left central and lateral incisors revealed the defects on nearly half of the labial surface. Case management: the incisal lapping technique were chosen to prepared teeth #21 and #22 for indirect porcelain veneer fabrications. Conclusion:  indirect porcelain veneers established an excellent esthetic result and restored the size, shape and color of anterior teeth with long term stability.

Abstract The role of lower third molars in lower incisor crowding is a debatable topic. Some believe the presence or eruption of lower third molars is associated with the crowding of mandibular incisors, others negate such association. Thirty-two newly debonded orthodontic patients, with ages ranging from 14-19 years, were randomly selected. No retainers were used for the lower dental arch. Removal of tight interproximal contacts of the lower anterior teeth was created and maintained by periodic abrasive stripping every 2-3 months, if needed. The cases were followed up for one year. Orthopantomographs (OPGs) and study casts were taken at debonding (post-treatment) and at the end of the one year follow up (post retention). Statistical analysis of the lower third molar conditions – erupted, unerupted, or missing with or without sufficient space for their eruption – versus re-crowding of lower incisors was evaluated using Fisher's Exact Test. The results of this pilot study revealed there was no significant correlation between the different conditions of the lower third molars versus lower anterior re-crowding in the absence of tight interproximal incisal contacts; however, a larger sample size is needed to verify such findings.

Abstract Rating patients with head trauma and multiple neurological injuries can be challenging. The AMA Guides to the Evaluation of Permanent Impairment (AMA Guides), Fifth Edition, Section 13.2, Criteria for Rating Impairment Due to Central Nervous System Disorders, outlines the process to rate impairment due to head trauma. This article summarizes the case of a 57-year-old male security guard who presents with headache, decreased sensation on the left cheek, loss of sense of smell, and problems with memory, among other symptoms. One year ago the patient was assaulted while on the job: his Glasgow Coma Score was 14; he had left periorbital ecchymosis and a 2.5 cm laceration over the left eyelid; a small right temporoparietal acute subdural hematoma; left inferior and medial orbital wall fractures; and, four hours after admission to the hospital, he experienced a generalized tonic-clonic seizure. This patient's impairment must include the following components: single seizure, orbital fracture, infraorbital neuropathy, anosmia, headache, and memory complaints. The article shows how the ratable impairments are combined using the Combining Impairment Ratings section. Because this patient has not experienced any seizures since the first occurrence, according to the AMA Guides he is not experiencing the “episodic neurological impairments” required for disability. Complex cases such as the one presented here highlight the need to use the criteria and estimates that are located in several sections of the AMA Guides.

Background: The aim of this study is to report the short-term results of catheter-directed foam sclerotherapy (CDFS) in the treatment of axial saphenous vein incompetence. Patients and methods: Data of all patients undergoing CDFS for symptomatic primary incompetence of the great or small saphenous vein were prospectively collected. Treatment results in terms of occlusion rate and patients’ grade of satisfaction were analysed. All successfully treated patients underwent clinical and duplex follow-up examinations one year postoperatively. Results: Between September 2006 and September 2010, 357 limbs (337 patients) were treated with CDFS at our institution. Based on the CEAP classification, 64 were allocated to clinical class C3 , 128 to class C4, 102 to class C5 and 63 to class C6. Of the 188 patients who completed the one year follow up examination, 67 % had a complete and 14 % a near complete obliteration of the treated vessel. An ulcer-healing rate of 54 % was detected. 92 % of the patients were satisfied with the results of treatment. We registered six cases of thrombophlebitis and two cases of venous thromboembolism, all requiring treatment. Conclusions: The short-term results of CDFS in patients with axial vein incompetence are acceptable in terms of occlusion and complications rates.

The main objective of this paper was to estimate and analyse transition-probability matrices for all 16 of Poland’s NUTS-2 level regions (voivodeship level). The analysis is conducted in terms of the transitions among six expenditure classes (per capita and per equivalent unit), focusing on poverty classes. The period of analysis was two years: 2015 and 2016. The basic aim was to identify both those regions in which the probability of staying in poverty was the highest and the general level of mobility among expenditure classes. The study uses a two-year panel sub-sample of unidentified unit data from the Central Statistical Office (CSO), specifically the data concerning household budget surveys. To account for differences in household size and demographic structure, the study used expenditures per capita and expenditures per equivalent unit simultaneously. To estimate the elements of the transition matrices, a classic maximum-likelihood estimator was used. The analysis used Shorrocks’ and Bartholomew’s mobility indices to assess the general mobility level and the Gini index to assess the inequality level. The results show that the one-year probability of staying in the same poverty class varies among regions and is lower for expenditures per equivalent units. The highest probabilities were identified in Podkarpackie (expenditures per capita) and Opolskie (expenditures per equivalent unit), and the lowest probabilities in Kujawsko-Pomorskie (expenditures per capita) and Małopolskie (expenditures per equivalent unit). The highest level of general mobility was noted in Małopolskie, for both categories of expenditures.

The United States is in a bind. On the one hand, we need millions of additional citizens with at least one year of successful post-secondary experience to adapt to the knowledge economy. Both the Gates and Lumina Foundations, and our President, have championed this goal in different ways. On the other hand, we have a post-secondary system that is trapped between rising costs and stagnant effectiveness, seemingly unable to respond effectively to this challenge. This paper analyzes several aspects of this problem, describes changes in the society that create the basis for solutions, and offers several examples from Kaplan University of emerging practice that suggests what good practice might look like in a world where quality-assured mass higher education is the norm.

Background: St. Petersburg is a city of federal importance with a large number of primary patients, identified annually. Objective: analysis of the main indicators characterizing medical care for children with cancer in St. Petersburg and the Leningrad region. Methods: The operative reports for 2013-2017 of the Health Committee of the Government of St. Petersburg and the Health Committee of the Leningrad Region were analyzed. Results. In 2013-2017 in the Russian Federation, 18 090 primary patients were identified, 927 (5.1%) of them in the analyzed subjects: in St. Petersburg - 697 (75,2%), in the Leningrad Region - 230 (24,8%). For 5 years, the number of primary patients increased in St. Petersburg - by 36%, in the Leningrad Region - by 2,5%. The incidence increased in St. Petersburg by 18,1% (from 14,9 in 2013 to 17,6 in 2017 per 100 000 of children aged 0-17). The incidence in the Leningrad Region fell by 4.9% (from 14.4 in 2013 to 13.7 in 2017). Mortality in 2016-2017 in St. Petersburg increased by 50% (from 2 to 3), in the Leningrad Region - by 12,5% (from 2,4 to 2,7). The one-year mortality rate in St. Petersburg increased by 3,9% (from 2,5 to 6,4%). In the Leningrad Region, the one-year mortality rate decreased from 6,5% in 2016 to 0 in 2017. The number of pediatric oncological beds did not change in St. Petersburg (0,9 per 10,000 children aged 0-17 years) and the Leningrad Region (0). In St. Petersburg patients were not identified actively in 2016-2017; in the Leningrad Region their percentage decreased from 8,7 to 0. The number of oncologists increased in St. Petersburg from 0,09 to 0.12 (+33,3%), in the Leningrad Region - from 0 to 0,03. Conclusion: Morbidity in St. Petersburg and the Leningrad region is significantly different, which indicates obvious defects in statistical data. Patients were not identified during routine preventive examinations which indicate a low oncologic alertness of district pediatric physicians. Delivery of medical care for children with cancer and the statistical data accumulation procedures should be improved.
