Immediate complete denture (ICD) is a mucosa-supported prosthesis manufactured before the removal of natural teeth and installed soon after their extraction. This paper aims to describe a clinical case of oral rehabilitation with upper ICD and lower removable partial denture (RPD). A 57-year-old female patient sought treatment with dissatisfaction with her aesthetics and mobility of the upper teeth. After anamnesis, intra and extra-oral examinations, radiographic examination and analysis of study models mounted on a semi-adjustable articulator, periodontal pockets were found in the upper teeth and extensive bone loss. So, upper tooth extraction, superior ICD and lower RPD were indicated as treatment. For ICD preparation, anatomical and functional moldings were made, made up of orientation and intermaxillary relationship plans for the assembly of the semi-djustable articulator models. The remaining upper teeth were removed from the model for assembly of the artificial teeth and the ICD was polymerized and polished. The lower RPD was made following the standard steps. After dentures manufacturing, the surgery for upper tooth extraction was performed and prostheses installed immediately after surgery. The results demonstrated that the performed treatment provided aesthetic, phonetic, and functional restoration to the patient avoiding her to undergo a period of edentulism. It was concluded that ICD is a good indication for prosthetic rehabilitation of patients with advanced periodontitis, whose planning is the exodontia of all the teeth of an arch.

Authors: Cunha Taís Morais Alves , Mendes Carlos Maurício Cardeal
Published: August 2021

Introduction: The maxillomandibular lateral growth imbalance with mandibular retrusion related to the maxilla indicates the skeletal Class II pattern. This craniofacial morphological abnormality is often attributed to nasorespiratory obstruction due to pharyngeal and palatine tonsils hypertrophy. The adenotonsillectomy is indicated to young patients with respiratory obstruction. However, there is no information in the scientific literature concerning the impact of tonsils surgically removal on craniofacial growth and development. Objective: To identify the association between adenotonsillectomy and skeletal Class II. Material and Methods: An unpaired case-control study was performed. Adult subjects who agreed to participate filled a questionnaire and after identification of the skeletal pattern through radiographic cephalometric analysis were allocated into two groups: CASE GROUP composed of 23 subjects with skeletal Class II malocclusion and CONTROL GROUP composed of 27 subjects without skeletal Class II malocclusion. With specific software the images were evaluated and measured to compare craniofacial measurements between the experimental groups and this data was interpreted to verify the association between skeletal Class II and the occurrence of adenotonsillectomy in early childhood. Results: the adenotonsillectomy demonstrated protective potential for skeletal Class II development due to a strong epidemiological association between adenotonsillectomy and skeletal Class II anteroposterior discrepancy (ORC = 0.33), without gender interference (ORA = 0.91). Conclusions: Among the long-term benefits of performing adenotonsillectomy in early childhood, it may be considered the prevention of craniofacial growth alterations such as Class II maxillomandibular discrepancy.

This study aims to determine the source of electrical energy in potatoes and lime. The method used is based on the principle that the salt content in potatoes is a solution, where salt is the solute and water is the solvent, so the ions can move freely. The movement of the ions in the potato can conduct electricity. For the contained acid lime affects the hardness of the composite, which affects the matrix and filler bonds. oxalic acid, which is in lime juice, is a type of electrolyte solution. In a voltaic cell, the electrolyte solution can function to deliver ions from the anode to the cathode so that it can produce electrical energy. Electrical energy is energy that is very important in life. Electrical energy is a basic human need so that potatoes and lime can be used as an alternative source of electrical energy.

The article is devoted to the issue of grammatical ambiguity of fractions in the modern Ukrainian language. It deals with particle ambiguity, paradigm and factors of grammaticality of fractions in the modern Ukrainian language. The pragmatic, syntagmatic and semantic-structural factors that determine the attribution of the analyzed words with a fraction in the modern Ukrainian language have been analyzed. The criteria used to distinguish grammatical functional homonyms are characterized. The main attention is paid to the grammatical criterion, as it allows to calculate the ratio of the distribution between the components of the combination of words or word combinations in a linear sequence. It has been revealed that adverbs are one of the most effective ways of formation of other parts of speech. Scientific novelty lies in the fact that grammatical ambiguity is a prerequisite for understanding the phonetic lobe as a structural-semantic unit of language.

In the maturing Malaysian market environment, co-branding is becoming a more common type of growth strategy. Despite being a scheme that could drive companies dedicated to it, some problems emerged tainting the scheme's original goals. Via searches in online databases such as ScienceDirect, Scopus, SpringerLink, and ProQuest ABI/ INFORM Collection, this paper identified related studies published between 1994 and 2019. This search strategy yielded 22 literatures that meet the conclusion requirements. Four patterns of co-branding issues in the hospitality industry which are management, marketing, product and service, and customer were found using content analysis.

Published: August 2021

E-hailing is an online transportation administration recognised as the travellers’ top pick in the transportation industry, including collaboration among clients and service providers. As clients now are more informed and can decide to choose any service provider they prefer, the e-hailing companies are obligated to fulfil and offer better support to their numerous clients, particularly for e-hailing administration. Keeping up consumer loyalty is vital for e-hailing’s specialist organisation to support upper hands. This research aims to investigate the role of safety and security, price, convenience and accessibility and whether they affect e-hailing service satisfaction. This research adopted a quantitative research methodology using a survey approach. Data was collected from 276 e-hailing services customers from higher learning institutions using an online survey. Data were analysed using the Statistical Package of Social Sciences (SPSS), and a few analysis were carried out, such as descriptive analysis, correlations and regression analysis. The results have shown that all factors have somehow affected e-hailing service satisfaction. This result will provide understanding to ridesharing service providers and can be used to improve their services by looking at the most and least influencing customer satisfaction. In the future, researchers could include diverse variables to study the customer satisfaction of e-hailing services in Malaysia.

The purpose of this research is to evaluate the precision of the Inverse Distance Weighted (IDW) to estimate and map the coastal water pH for the sustainability of Pulau Tuba, Langkawi, Kedah. 30 sampling points have been set up during two sampling activities in November 2018. The pH meter has been calibrated and lowered to 1 meter below the water surface to measure the reading of pH. The development of the spatial model was developed using the spatial analyst tool available in ArcGIS Software. Several types of statistical analyses were carried to compare the observed and predicted value of pHs such as correlation analysis, regression analysis, and error analysis. Accuracy assessment was carried later after the transformation of a spatial model into a surface map. The research found that the IDW method successfully interpolated the pH readings. The research found that there is a strong positive correlation between the observed and predicted values. For error analysis, Mean Absolute Error (MAE) and Root Mean Square Error (RMSE) were recorded at 0.033 and 0.044, respectively. After the transformation of the spatial model to the surface map, the accuracy of the map is recorded at 81.25%. The map produced can be used by residents and local government for social and economic development and protection of biodiversity at the coastal water of Pulau Tuba, Langkawi, Kedah.
