The Act No. 23 of 2003 on Children Protection obligates the state and government to ensure children protection, maintenance, and welfare. A child who obtains criminal sentence has been protected by the government based on the Act No. 12 of 1995 on Children Immurement. The Act pays attention to their interests in order to not eliminate the child's future. The children criminal sanction is given as a process of building children awareness to understand the better future. A form of the government protection to children is legislation on children welfare, juvenile justice, human rights, children immurement, and children protection. The children and adolescents committing the criminal acts are very serious issues to immediately overcome by the concerned parties i.e. the parents, police, and teachers that have many direct contact with children and adolescents. The police are expected to take action against any perpetrators of crimes, including those committed by children and adolescents. Meanwhile, the parents and the teachers are expected to give serious guidance in order that they are able to be the pride of, not the ‘dregs of society’.
Spaces of Innovation and Women Rural Entrepreneurship in Italy
Authors:   Marcello De Rosa, Luca Bartoli, McElwee Gerard
Published: September 2021

This paper deals with “gendering innovation”, with the purpose of exploring the entrepreneurial spaces of innovation among Italian farms managed by women. More precisely, the hypothesis is that entrepre-neurial orientation has to be considered the engine of innovation adoption in different rural contexts, by creating new spaces for innovation. The research is grounded on primary sources using a questionnaire administered to a sample of women farmers in all regions of Italy, with the purpose of investigating complex dimensions behind the decision of innovation uptake, with a special focus on the relevance of entrepreneurial orientation. Empirical analysis lets different “worlds of female innovation” to emerge, which are grounded on both conventional and alternative agrifood networks. Taking on the perspective of entrepreneurial spaces of innovation implies to design a diversified set of policy action with the purpose of affecting these entrepreneurial spaces. This is particularly urgent in the perspective of gender main-streaming of rural development policies of the European Union.
Factors Affecting the Adoption of Technology in Dairy Farms in the Konya Region of Turkey.
Authors: Yener Ögür Aysun
Published: September 2021

This study aimed to determine the factors affecting the technology adaptation of dairy farms. For this purpose, according to the stratified random sampling method, 125 dairy farms were determined as the sample size. In the analysis of the factors affecting the technology adaptation of dairy farms, a “tech-nology usage index” was created according to the current technology usage situations of the producers. Factors affecting the technology adaptation of dairy farms were determined by multiple linear regression analysis. According to the multiple linear regression analysis results, education, experience/age ratio, workforce, credit usage status, participation in extension activities and income were found to be statisti-cally significant at the 5% level. The yield was found to be significant at the 10% significance level. En-terprises using low and high technology follow technologies from other farmers in the village, television and dealers in the district. Lead farmers should be used in agricultural extension activities and mass media should be used.
Prokrastination und die Gunst der Stunde
Authors: Kauß Anja
Published: September 2021

In »Prokrastination und die Gunst der Stunde« nimmt Anja Kauß eine kulturhistorische Ortsbestimmung des Prokrastinationsbegriffs vor. Entgegen gegenwärtiger Auffassungen von Prokrastination als dysfunktionales Aufschieben unangenehmer Aufgaben hebt sie dabei abwägende, strategische und bewegungspolitische Aspekte prokrastinierter Entscheidungen hervor. Dieser Doppelcharakter der Prokrastination kommt in der antiken mythologischen Figur des Kairos auf den Begriff. Es galt in diesem Bild den vorbeieilenden Gott im richtigen Augenblick an seiner Haartolle zu packen, das Aufschieben der Handlung entsprach also rationalem Interesse. Die Rationalität der vermeintlich irrationalen, dysfunktionalen Prokrastination arbeitet Kauß zuletzt mit Freud heraus, der den Widerstand gegen eine Handlung als Kulturtechnik und Ausdruck unbewusster Konflikte charakterisiert.

Published: September 2021

Der Artikel verknüpft die Zeitlichkeit der Prokrastination mit ästhetischen Aktivitäten und Strategien des Aufschiebens. Prokrastination weist eine starke Verbindung zu Melancholie und Krise auf und beeinflusst wie diese die Beziehung von Objekten und Bedeutungen. Dazu wird von der Beobachtung ausgegangen, dass Ästhetiken der Prokrastination vermehrt im Theater seit 1990 auftreten, und untersucht, wie in den Produktionen von drei KünstlerInnen zu unterschiedlichen Zeitpunkten seitdem damit umgegangen wird. Dabei wird nachgezeichnet, wie Marthaler und Quesne ein neues Theater in der Verschiebung von Zeit und Bedeutung erfinden, während dieser Prozess bei Langsdorf blockiert wird.
Transkulturelle Entwicklung des Prokrastinationskonzepts
Authors: Otermin-Cristeta Solange
Published: September 2021

Das Konzept Prokrastination beinhaltet positive und negative Seiten, die in verschiedenen Epochen und Kulturen anders bewertet werden, von dem antiken Rom bis heute, von Westen bis Osten. Wir werden diese Aspekte betrachten und versuchen sie zu verstehen, möglichst unabhängig von moralischen Vorurteilen. Die Entwicklung dieser moralischen Dogmen ist auch wichtig für uns, um zu begreifen, was für eine soziale Funktion die Prokrastination in verschiedenen Gesellschaften hat. Die Hauptlaster der katholischen Kirche, die Arbeitskultur der Reformation oder das zeitgenössische Japan verwerfen Faulheit und loben Leistungsfähigkeit. Verschiedene Autoren in der Psychologie versuchen, das Prokrastinationskonzept wissenschaftlich zu definieren. Zum gegenwärtigen Zeitpunkt gibt es noch keine offizielle Diagnose und kaum einen wissenschaftlichen Konsens. Wir wissen aber, dass laut internationalen Befragungen rund 20 Prozent der Bevölkerung jeweils in verschiedenen Ländern sich als Prokrastinierende sehen (Beck et al., 2000) und dies als problematisch und emotional belastend empfinden. Anhand der genannten Gründe ist es wichtig, einen tieferen und breiteren Blick auf das Thema Prokrastination zu werfen. Dieser Artikel versucht, Prokrastination in verschiedenen kulturellen und sozialen Kontexten zu beschreiben sowie unterschiedliche psychologische Schulen und Autoren zusammenzubringen.
Die Mitte der Nation
Authors: Mayer Patrick
Published: September 2021

In den Ermittlungen zur Mordserie des NSU ist eine eklatante Blindheit der Sicherheitsbehörden in der Wahrnehmung von Rassismus sichtbar geworden. Es stellt sich daher die Frage, ob die Kategoriensysteme zur Erfassung rassistischer Gewalt ausreichend sind. Der sogenannten »Extremismustheorie« kommt dabei ein zentraler Stellenwert zu. Ausgehend von einer Sozialpsychologie des Nationalgefühls kann gezeigt werden, dass die Kategorie der »Mitte«, wie sie von diesen Ansätzen formuliert wird, leicht mit der nationalen Eigengruppe identifiziert werden kann und eine solche Identifikation von VertreterInnen der »Extremismustheorie« auch nahegelegt wird. Die Erkennung politisch motivierter Gewalt wird dabei an die Wahrnehmung eines Angriffs auf die nationale Eigengruppe geknüpft, die bei rassistischer Gewalt ausbleibt. Dies könnte einer der Gründe für das Nichterkennen des rassistischen Motivs der NSU-Morde sein.
Die Unmöglichkeit zu Trauern
Authors: Schleimer Simon Moses
Published: September 2021

Kinder und Jugendliche wurden in der internationalen Migrationsforschung lange Zeit eher vernachlässigt. Der Ansatz der transnationalen Migration hat ihre Perspektive als Akteure verstärkt in den Diskurs einbezogen. Dieser Beitrag diskutiert die Herausforderungen transnationaler Migration anhand von narrativen Interviews mit Kindern, Jugendlichen und jungen Erwachsenen, die mit ihren Familien aus Deutschland in die Region Kurdistan im Irak remigriert sind. Das Datenmaterial wurde nach der Methode des Szenischen Verstehens nach Lorenzer (2006 [1985]) ausgewertet. Auf der Grundlage eines Fallbeispiels wird gezeigt, dass transnationale Migrationsbewegungen Krisen auslösen können, deren Bewältigung notwendig ist, um von transnationalen Lebenspraktiken profitieren zu können.

Die Psychologie des Gedächtnisses zeigt, dass Menschen ihre subjektive Vergegenwärtigung und soziale Darstellung der eigenen Vergangenheit einer steten Revision unterwerfen. Von besonderer Brisanz ist das dort, wo Menschen im Nachhinein mit dem Vorwurf der Täterschaft konfrontiert werden. Anhand einer Einzelfallanalyse führt der Beitrag aus, welche Strategien der kommunikativen Verantwortung den Beschuldigten in solchen Fällen zur Verfügung stehen. Davon ausgehend wird der grundsätzliche Zusammenhang von Selbstverhältnis und Selbstdarstellung im Kontext moralischer Emotionen beleuchtet.

Study of the vessels of the upper extremities and the rhythm of heart activity in patients with vibration disease in the post-СOVID period
Authors: Kuprina Nadezhda I. , Ulanovskaya Ekaterina V. , Shilov Viktor V. , Serdyukova Dina N.
Published: September 2021

Currently, there are many consequences of the new coronavirus infection. We shall study the actual long-term consequences of this disease for population health in the coming years. It is necessary to consider concomitant chronic diseases in patients who are particularly dangerous in the post-COVID period. Vibration disease is one of the leading occupational pathologies in the Russian Federation. Symptoms of vibration disease are vegetative-vascular disorders, cold, cyanosis, paresthesia, violation of regional blood circulation of the extremities. As is known from numerous sources, the defeat of the cardiovascular system (CVS) against the background of COVID-19 infection occurs through angiotensin-converting enzyme (ACE-2) receptors, which presents in large numbers in the endothelium of veins and arteries. The study aims to research hemodynamics features in patients with vibration disease after a new coronavirus infection. In the clinic of occupational pathology, the researchers examined 28 patients with a previously established diagnosis of VD after a coronavirus infection. We did a Holter ECG, ultra-sound examination of the arteries and veins of the upper extremities. Arrhythmias in the form of supraventricular extrasystoles, paroxysms of atrial fibrillation, positional sinus tachycardia occur in patients with VB after a new coronavirus infection on an ECG and daily monitoring of the ECG by Holter. As is known, cardiac arrhythmias are essential in the development of acute and chronic vascular pathology, characterized by a decrease in arterial blood filling and changes. Ultrasound of the vessels of the upper extremities revealed moderate expansion of the radial and ulnar veins, insufficiency of the valve apparatus during functional tests, increased venous outflow. There was also an increase in the indicators of peripheral vascular resistance, which indicates violations of the tonic properties of the vessels of the upper extremities and violations of vasodilation. Scientists identified violations of the tonic properties of blood vessels in patients with vibration disease in the post-COVID period on ultrasound, arrhythmias in the form of supraventricular extrasys-toles, paroxysms of atrial fibrillation, positional sinus tachycardia on daily ECG monitoring.

UBASH3A expression associates with survival in triple negative breast cancer.
Authors: Mamoor Shahan
Published: September 2021

We mined published microarray data (1) to understand the most significant gene expression differences in the tumors of triple negative breast cancer patients based on survival following treatment: dead or alive. We observed significant transcriptome-wide differential expression of ubiquitin-associated and SH3 domain-containing A, encoded by UBASH3A when comparing the primary tumors of triple negative breast cancer patients dead or alive. Importantly, UBASH3A expression was significantly correlated with overall survival in basal subtype breast cancer, a molecular subtype sharing significant overlap with triple negative breast cancer. UBASH3A may be of relevance as a biomarker or as a molecule of interest in understanding the etiology or progression of triple negative breast cancer.
Design and Implementation of Electromyography (EMG) based Real-Time Pattern Recognition model for Prosthetic hand Control
Authors: Jayaweera Pasan Yashoda
Published: September 2021

Surface electromyogram (EMG) signals are a key component in myoelectric control systems utilized in modern prosthetic devices. Despite extensive study into EMG gesture detection techniques for hand and arm gestures, most prosthetic devices rely on direct control approaches that are often confined to single movements. The purpose of this paper is to investigate various feature extraction techniques and to compare various machine learning algorithms, window sizes to identify the most suitable algorithm, window size for real-time gesture recognition. For this purpose, a publicly available pre-labeled 2-channel EMG dataset was used as EMG signals. Feature sets for each window size were extracted using various feature extraction techniques and fed into support vector machines, k-nearest neighbors, ensemble learning, and feed-forward artificial neural network (ANN) classifiers. The feed-forward neural networks classifier was determined to be the best classifier based on its accuracies, sizes, and prediction delays for each window size. The maximum accuracy of the feed-forward ANN classifier was ≈87% with a 300-millisecond window size. the use of the majority voting technique was considered in terms of the number of votes and the window sizes.

Lower levels of directed exploration and reflective thinking are associated with greater anxiety and depression
Authors: Smith Ryan , Taylor Samuel , Wilson Robert C , Chuning Annie E. , Persich Michelle , Wang Siyu , Killgore William
Published: September 2021

Anxiety and depression are often associated with strong beliefs that entering specific situations will lead to aversive outcomes – even when these situations are objectively safe and avoiding them reduces well-being. A possible mechanism underlying this maladaptive avoidance behavior is a failure to reflect on: 1) appropriate levels of uncertainty about the situation, and 2) how this uncertainty could be reduced by seeking further information (i.e., exploration). To test this hypothesis, we asked a community sample of 417 individuals to complete measures of reflective cognition, exploration, and symptoms of anxiety and depression. Consistent with our hypotheses, we found significant associations between each of these measures in expected directions (i.e., positive relationships between reflective cognition and strategic information-seeking behavior or “directed exploration”, and negative relationships between these measures and anxiety/depression symptoms). Further analyses suggested that the relationship between directed exploration and depression/anxiety was due to an ambiguity aversion promoting exploration in conditions where information-seeking was not beneficial (as opposed to under-exploration when more information would aid future choices). In contrast, reflectiveness was associated with greater exploration in appropriate settings and separately accounted for differences in reaction times, decision noise, and choice accuracy in expected directions. These results shed light on the mechanisms underlying information-seeking behavior and how they may contribute to symptoms of emotional disorders. They also highlight the possibility that reflectiveness and exploration could represent novel treatment targets for those who show low levels of these tendencies – consistent with the need to develop individualized precision medicine approaches within computational psychiatry.
Maass, Pavon & Suitner HARMONIC ANALYSIS OF SOCIAL COGNITION
Authors: Maass Anne
Published: September 2021

In this paper, we argue that some fundamental concepts and tools of signal processing may beeffectively applied to represent and interpret social cognition processes. From this viewpoint,individuals or, more generally, social stimuli are thought of as a weighted sum of harmonics withdifferent frequencies: Low frequencies represent general categories such as gender, ethnic group,nationality, etc., whereas high frequencies account for personal characteristics. Individuals arethen seen by observers as the output of a filter that emphasizes a certain range of high or lowfrequencies. The selection of the filter depends on the social distance between the observingindividual or group and the person being observed as well as on motivation, cognitive resourcesand cultural background. Enhancing low- or high-frequency harmonics is not on equal footing, thelatter requiring supplementary energy. This mirrors a well-known property of signal processingfilters. More generally, in the light of this correspondence, we show that several established resultsof social cognition admit a natural interpretation and integration in the signal processinglanguage. While the potential of this connection between an area of social psychology and one ofinformation engineering appears considerable (compression, information retrieval, filtering,feedback, feedforward, sampling, aliasing, etc.), in this paper we shall limit ourselves to layingdown what we consider the pillars of this bridge on which future research may be founded.
Hearing "birch" hampers saying "duck" – An ERP study on phonological interference in immediate and delayed word production
Authors: Mädebach Andreas , Widmann Andreas , Posch Melina , Schröger Erich , Jescheniak Jörg D.
Published: September 2021

When speakers name a picture (e.g., “duck”), a distractor word phonologically related to an alternative name (e.g., “birch” related to “bird”) slows down naming responses compared to an unrelated distractor word. This interference effect obtained with the picture-word interference (PWI) task is assumed to reflect the phonological co-activation of close semantic competitors and is critical for evaluating contemporary models of word production. In the present study, we determined the event-related brain potential (ERP) signature of this effect in an immediate and a delayed version of the PWI task. ERPs revealed a differential processing of related and unrelated distractors: an early (305 – 436 ms) and a late (537 – 713 ms) negativity for related as compared with unrelated distractors. In the behavioral data, the interference effect was only found in immediate naming, while its ERP signature was also present in delayed naming. The time window of the earlier ERP effect suggests that the behavioral interference effect indeed emerges at a phonological processing level, while the functional significance of the later ERP effect is as yet not clear. The finding of a robust ERP correlate of phonological co-activation might facilitate future research on lexical processing in word production.

Pro Bono in South Africa
Authors: Pooe Thabang , Brown Alice , Klaaren Jonathan
Published: September 2021

This chapter explores issues related to the state of pro bono legal services and access to justice in South Africa. As is made clear in this book, what is referred to as “pro bono” comes from the Latin pro bono publico, meaning “for the public good.” It describes legal work undertaken by legal practitioners without remuneration or at significantly below-market rates as a public service for individuals or organizations who cannot afford to pay. In the South African context, the concept of pro bono must be understood alongside specific constitutional provisions as well as against the structure of the legal profession. In our view, increasing access to justice for the poor, marginalized, and indigent individuals and communities should be seen by members of the South African legal community as an essential component to fulfilling not only their civic duty but also their constitutional obligations. Our understanding of pro bono includes aspirations of access to justice with the legal profession playing a part in its realization. This can only be made real for all people living in South Africa if they have access to legal representation, and much of the private legal profession understands and acknowledges that it has anobligation in this regard. Pro bono practice is therefore a necessary institution for addressing access to justice. It is not, however, sufficient. Pro bono practice must be augmented by the work of paralegals and extended to the particular South African vision of community service, which itself does aspire to implement and achieve access to justice.

Aim: To evaluate the debridement efficacy of different irrigation systems in simulated canal irregularities. Study Design and Setting: About sixty maxillary central incisors were selected and after chemomechanical preparation were split longitudinally into two halves. Each groove and depression were filled with dentine debris mixed with 2.5 % NaOCl to simulate a situation where dentine debris accumulates in the un-instrumented extensions of the root canal. Materials and Methods: The specimens were randomly divided into 4 experimental groups as follows: Group I - Conventional Needle Irrigation, Group II - Apical Negative Pressure Irrigation (EndoVac), Group III - Passive Ultrasonic Irrigation and Group IV - Combination Irrigation (EV+PUI). 9 ml of 2.5 % NaOCl, 9 ml of 17 % EDTA and 9 ml of saline was used for the final irrigation protocol. Images were taken before and after irrigation using PRIMA DNT surgical microscope with digital camera. Statistical Analysis: The intergroup and individual comparison of percentage reduction of debris in groove and depressions were carried out by using Kruskal-Wallis and Mann-Whitney U tests respectively. The intergroup comparison for different scoring criteria was compared using Pearson’s chi-square tests. Differences were considered statistically significant at P value < 0.05. Results: The combination group, EV group and PUI group showed better removal of debris in Groove and Depressions than Conventional needle irrigation group. The Combination group had significant reduction of debris at 2 mm level when compared to all the other groups. Conclusion: The effectiveness of this combination irrigant delivery system for smear layer removal and antibacterial efficacy have to be evaluated further in future clinical studies

Background: Auricular Acupuncture/acupressure is a Chinese methodology used to cure disease. The principle based on auricular acupuncture/acupressure is the yin and yang energy through which the organ in our body gains stability. If the yin and yang energy is not stable disease occurs. The role of auricular acupuncture/acupressure for smoking cessation has much less review of literature to prove its effectiveness. Aim: To assess the effectiveness of auricular acupuncture/acupressure as one of the intervention for smoking cessation. Study Design: A systematic review of controlled trials and pilot study was performed. Electronic and hand search retrieved 583 records, 288 were screened. The intervention and outcomes were assessed in the study included for systematic review. Results: Five studies were included in our systematic reviews which were randomized control trials and pilot studies. There were studies performed in different countries. Among the five trials, two were found statistically significant, but further studies should be done to prove the effectiveness of auricular acupressure for smoking cessation. We were not able to conduct Meta-analysis due to clinical heterogeneity among the study design and difference occurred in reporting of data. Conclusion: There is a lack of evidence to show the effectiveness of auricular acupuncture/acupressure for Smoking cessation, so further pilot studies and control trials should be done to evaluate the effectiveness of auricular acupuncture /acupressure.

Background of the study: Dental implants are one of the most sought-after choice of treatment for restoration and rehabilitation of missing teeth. However, the accuracy of the removable or fixed superstructures over the dental implants is influenced for a major proportion by the impression techniques and materials. This paper discusses the comparison of the accuracy of different impression materials and techniques used in the second stage of the dental implant treatment in vivo. Objective: The objective of the paper is to study the comparison of the accuracy of different impression materials and techniques used in the second stage of the dental implant’s treatment in vivo. Search methodology: Electronically key searched in scientific literature databases. Selection criteria: Based on the set inclusion and exclusion criteria such as studies conducted in partial edentulous arches, in the age group of 30 to 55 years. Data collection and analysis: A total of 248 literatures were found to be relevant to the framed topic and were scrutinised based on the dejected criteria and 18 kinds of literature obtained were taken into consideration. Main Result: Among the different impression materials taken into the comparative study, it was observed that polyvinyl siloxane exhibited a dimensional accuracy slightly greater than polyether. However, light body putty exhibited greater accuracy than medium body putty. Various impression techniques were compared to evaluate the dimensional accuracy of the impression. It was observed that the open tray technique and splinted impression technique produced a more dimensionally stable impression than the other techniques. Authors Conclusion: this study to assess the accuracy of various impression material and methods has concluded that while impression techniques influence the accuracy of the impression, the impression materials namely the Polyvinyl siloxane and polyether exhibit no significant difference with a slight preference to the polyvinyl siloxane. Hence the choice of impression material is at the discretion of the dentist performing the treatment and also this area requires further studies to establish conclusive evidence.

Published: September 2021

The temporomandibular joint (TMJ) is the joint of the mandibular condyle with the glenoid fossa of the temporal bone and is the only joint in the head that is responsible for opening and closing movements of the jaw. Cliking is the most frequent symptom indicating temporomandibular joint dysfunction. Several radiographic techniques are used to establish the diagnosis in the examination of the temporomandibular joint. This research was carried out using closed mouth TMJ radiography. The purpose of this study was to determine the height and width of the mandibular condyle and the form of eminence with and without clicking using TMJ radiographs. This research is a descriptive analytic study. The results showed that the average height of the mandibular condyle with clicking was 18,796 mm and without clicking was 22,812 mm. The average width of the mandibular condyle with cliking is 11673mm and without cliking is 11,181mm. The average form of articular eminence with clicking is 36.754 ° and without cliking is 41.081 °. The conclusion of the study was that using the Independent t test there were significant differences in the height of the mandibular condyle and the shape of the articular eminence but there was no significant difference in the width of the mandibular condyle with and without clicking using TMJ radiographs.

Background: The purpose of using tooth cleaning aids like chewing stick, toothbrush with locally made powder or fluoride containing toothpaste, is to attain good oral hygiene compatible with good oral health. Aim: To determine the oral hygiene status of public primary school children in a rural community in South-east Nigeria. Methodology: A cross sectional descriptive study of primary school children was done in a public primary school in Nkanu -West local Government Area of Enugu State. Ethical clearance for this study was sought and obtained, all participants who gave their assent were recruited. Socio-demographic data was obtained using interviewer -administered questionnaire. Oral hygiene status was determined using simplified oral hygiene index (OHI-S). After data collection, oral hygiene education and tooth brushing demonstrations were done. Data were analysed using Statistical Package for Social Sciences (SPSS) Version 20. P values < 0.05 were accepted as being statistically significant. Results: 57(46.3%) males, 66(53.7%) females were seen and examined, giving a male to female ratio of about 1:1.2. The age range of the participants was 8 to 14 years with a mean age of 10.2 ± 1.4 years. The mean OHI-S score was 1.5 ± 0.4. 80 (65.0%) had fair oral hygiene, 41(33.3%) had good oral hygiene while 2(1.7%) had poor oral hygiene status. Majority of the school children brush their teeth once daily, using the horizontal scrub technique. Conclusion: In this study, most of the school children had fair oral hygiene status. Good oral hygiene status was seen more among 9-10 year old children, while fair oral hygiene status was seen more among 10-11 year children. The association between oral hygiene status with age or gender was not statistically significant.

Aim: To find sites in human temporal bone for placing longer implant Materials & Methods: Dry human skull were procured from the anatomy department. External acoustic meatus(EAM) was taken as reference point from that point five arcs of radius15mm, 20mm,25mm,30mm,35 mm were drawn over the temporal bone. The temporal bone removed from the skull and the bone is removed from the outer most point towards the EAM. The thickness of the bone at 1oClock and 4o Clock position and 8oClock and 11o Clock position over the left and right side of the temporal measured using digital Vernier calliper. The temporal bone is thicker at the 3oClock on the left and 9oClock on the right side. The thickness at the new position also measured. Result: The mean bone thickness at 15mm, 20mm, 25mm ranges from 3.92 to 12.08mm. The mean bone Thickness at the 3oclock and 9 o clock position at the distance of 20mm from EAM ranges from 8.21 to 8.50mm.The Statistical significance within the group were analysed using paired t test and found to be statistical significant at P value less than. 05. Conclusion: The external surface of temporal bone at the 3oClock on the left and 9oClock on the right side denser and thicker. The bone availability is also more favours for placing longer implant.

Background: Despite improvements and advances in materials and methods, root canal treatment is not always satisfactory. After completing the obturation procedures, retreatment might be mandatory in cases of reinfection or inappropriately cleaned root canal. Retreatment strategy involves elimination of the obturating material, and then the whole mechanical and filling procedures are repeated again. Thus, root canal sealers removal shouldn’t represent an obstacle. Objective: The current study aimed is to investigate and observe the cleanliness of root canal walls that were previously obturated with two types of calcium silicate bioceramic sealers compared to a resin sealer. Materials and Methods: 21 single-rooted premolars were utilized. After complete removal of the obturating materials using Protaper retreatment universal system, the roots were cut by the use of a hammer and a chisel, then the middle third of the retreated canals were observed under a scanning electron microscope at magnification 1000x, the amount of clear, opened dentinal tubules was compared. Results: Among the three investigated sealers, ADSEAL showed the largest number of clear dentinal tubules while, a fewer open dentinal tubule were observed with Well Root and Ceraseal. Conclusions: None of the investigated sealers could be totally removed from root canal walls. However, the quantity of remnants of root filling material with well root and ceraseal were significantly more, compared to ADSEAL.

Gingival fibromatosis is a clinical condition that is characterized by gingival overgrowth. It is often caused due to medication, hereditary reasons and other local factors. When the etiology is unknown, they are referred as Idiopathic gingival enlargement (IGE). IGE is a rare and is often occurs as a manifestation of an underlying syndrome or as a separate entity. They clinically appear as gingival overgrowth with firm consistency with both deciduous and permanent dentition equally affected and worsens during adolescence. IGE is a slowly growing benign growth affecting all anatomic parts of the gingiva leading to esthetic and functional problems with difficulty in speech, mastication and deglutition. This leads to plaque accumulation which complicates the previous gingival enlargements. There are many cases reporting the idiopathic gingival enlargement in the literature, but here we report a rare case of non-syndromic association of IGE, chronic periodontitis and plasma cell gingivitis in an older patient.

Uremic frost is a rare dermatological manifestation of severe azotemia. It is rarely seen today because of early dialytic intervention. It occurs when high concentration of urea and other nitrogenous waste products accumulate in the sweat and then crystallizes as deposit on the skin after evaporation in a process called uridrosis or urinous sweat. Its a sign of impending renal failure and portends bad prognosis. Involvement of urea transporters may have a role in its development. Damage to the cutaneous microvasculature, eccrine sweat and sebaceous glands may be responsible for the high level of urea accumulation on skin. The test to analyze that the crystalline material is urea or nitrogenous waste products, the scrapings of the sample can be dilutad in normal saline and then tested for elevated urea nitrogen level. No specific therapy except correcting the underlying etiology
