Assessing the efficiency of drinking water treatment plant and the impact of broken distribution systems on water quality of Wukari-Ibi plant
Authors: Ezekiel Samaila , Joshua Williams , Gin Williams Abel
Published: April 2022

Water treatment is essential in the provision of potable drinking water to communities. However, studies have shown that many local conventional drinking water treatment plants in Nigeria are ineffective in removing contaminants. This study evaluated the efficiency of drinking water from Wukari-Ibi plant by assessing water samples before and after treatment and comparing results to national and international drinking water standards. Forty water samples were collected and selected physical and biological parameters were determined according to standard laboratory procedures. The results indicated that after treatment, turbidity (6.74 NTU) and coliform count (17 cfu/100 mL) were still significantly greater than standard guidelines, which suggest that the treatment plant is unable to reduce the concentration of these contaminants to a safe level for consumption. Furthermore, assessing water at consumer taps indicated that broken distribution system is likely serving as a potential pathway for contamination. The plant removal efficiency of colour, turbidity, Total Dissolved Solids, hardness, and coliform count was computed as 74.7%, 66.57%, 32.58%, 30.11%, and 59.88% respectively. Overall, the removal efficiency was 52.77% which is considered unacceptable for the supply of potable drinking water. The study concludes that cost and poor skilled personnel are the major factors in the inefficient treatment and therefore we suggest a low-cost treatment using activated carbon from locally sourced plants to be incorporated for effective removal of contaminants. There is also a need for government to invest in infrastructure and equipment so as to upgrade the treatment plant.

Authors: Sarianoferni  , Astuti Eha Renwi
Published: April 2022

Diagnostic radiology supports the detection of diseases and disorders in the oral cavity, disease progression, and treatment plan-ning, which is indispensable in the field of dentistry. Improvements in imaging technology have consequently increased the use of radiography. The effective dose is relatively low, but the need for repeated radiographic examinations results in an increase in the total dose received. This repeated increases the reception of radiation doses for both patients and workers. This paper reviews the ability of X-rays to penetrate solid objects for diagnostic purposes and the biological effects they cause on human cells. Dental X-ray radiation has many benefits but also has the potential to interfere with the health of cells and tissues. Its use must be ma-naged properly and carefully. Radiation protection procedures for patients, radiographers, and the surrounding environment should be a major concern.

Published: April 2022

The method of chemically cleaning dentures by immersion in an effervescent denture cleanser solution for a long time can affect the transverse strength. Betel leaf extract can be used as a natural disinfectant because it contains essential oils that are antimi-crobial by denaturing cell proteins. This study was intended to examine the decrease in the transverse strength of heat polymeri-rized acrylic resin plates after immersion in 15% betel leaf extract solution. The posttest only control group design study used a sample of 24 HPAR plates, which were divided into 6 groups. The plates were immersed in distilled water for 72 hours to re-duce the residual monomer, immersed in 15% betel leaf extract solution, the positive control group in Fittydent® and the nega-tive control group in aquadest for 1 and 6 hours. The transverse strength was tested using the Universal Testing Machine and the data were analyzed using the one-way Anova test. The results showed the average transverse strength after immersion for 1 hour in 15% betel leaf extract, Fittydent®, and aquadest, respectively, namely 46.512±10.965 MPa, 72.744±22.395 MPa, and 81.522±28.854 MPa; after soaking for 6 hours, respectively, namely 49.171±14.246 MPa, 73.894±25.844 MPa, and 71.860± 17.553 MPa.

Radiographic examination was performed to evaluate the apical condition of the fractured tooth followed by initial im-pression for diagnostic wax-up, treated endodontically to prevent pulp necrosis. Preparation was carried out on tooth 21 using gingival retraction floss and the patient using provisory for 4 weeks. The final impression of the double impression technique was carried out with polyvinylsiloxane. The bridge is cemented using dual-cure resin cement. It is concluded that this ovate pontic design is very suitable for the treatment of the anterior region to achieve the best esthetic result as the main requirement.

Authors: Sugiaman Lestari Hardianti , Natsir Nurhayaty
Published: April 2022

This article describes about the apexification of open apex with apical plug in immature permanent maxillary incisor teeth. A 12-year-old girl came to the Dental Hospital Hasanuddin University with a complaint of cavities in her upper front teeth. The teeth were filled one year ago, and it fell out about six months later. The right upper tooth had been swollen and sore a few days be-fore. There is a history of colliding at the age of 8 years. Radiographic examination showed a wide root canal on tooth 11 and an open apex with radiolucency in the apical area on teeth 11 and 21. So the diagnosis of these teeth was chronic apical abscess and asymptomatic apical periodontitis, respectively. After performing open access, the root canal was prepared using conventional cir-cumferential techniques, then dressing using calcium hydroxide was given for 2 weeks. Next, the apical plug procedure was per-formed using MTA. The patient showed no complaints of pain after treatment, and the size of the radiolucency image in the pe-riapical area of ​​the tooth was reduced. So, it is concluded that apexification treatment with apical plug is one of the effective treatment methods to overcome the problem of open apex in immature permanent teeth.

Wilckodontics-an interdisciplinary periodontics-orthodontic approach to accelerate orthodontic treatment time: a literature review
Authors: Rahma Mansyur Shinta , Andi Adam Mardiana
Published: April 2022

Objective: Orthodontic treatment is the longest dental procedure performed. To accelerate tooth movement, orthodontists and periodontists have developed a new technique, termed Wilckodontics or periodontal accelerated osteogenic orthodontics. This technique combines selective alveolar corticotomy techniques, particulate bone grafts, and orthodontic force. This review aims to discuss the concepts and technique of Wilckodontics as a combination of interdisciplinary treatment. Methods: An internet-based search was conducted to identify various literatures discussing Wilckodontics using several keywords. Results: Wilcko-dontics can accelerate tooth movement in adult patients and shorten treatment time. Compared with conventional orthodontic treatment, this technique shows advantages in terms of treatment cycle and treatment effect. In addition, the Wilckodontics does not increase the risk of root resorption, periodontium injury, and alveolar bone defects. Conclusion: Wilckodontics re-quires various diagnostic parameters and modification of the procedure. With the right synergy of orthodontist and periodon-tist, successful treatment can be achieved.
Novel fully digital workflow for removable partial denture fabrication
Authors: Jubhari Eri Hendra , Yoviani Sole Priscilia
Published: April 2022

Background: Digital dentistry technology based on computer-aided design and computer-aided manufacturing (CAD/CAM) has been widely applied in the field of prosthodontics, ranging from digital techniques for impression processes, jaw registration, artificial tooth arrangement and base design, along with base and denture fabrication. However, conventional analog workflows are still used and digital workflows have not completely replaced analog workflows. Purpose: Knowing the latest complete digi-tal workflow in the manufacture of removable partial dentures (RPD). Methods: Full-arch digital impressions of the partially edentulous jaw were made with an intraoral scanner or by conventional methods. The denture framework, artificial teeth, and denture base were designed by commercially available CAD software. Each of the denture components including connectors, clasps, and artificial teeth and the denture bases were fabricated separately by the CAM machine, and then assembled using an adhesive material. Conclusion: RPDs were successfully fabricated using a fully digital workflow and no clinical complications were reported.

Authors: Nurmaifah  , Gazali Mohammad , Tajrin Andi
Published: April 2022

Background: Bleeding is a recognized complication, frequently encountered immediately following the removal of a tooth. This bleeding can be easily controlled in most cases, and almost completely stops within eight hours after the extraction. However, sometimes it may continue, resulting in a life‐threatening situation. Cases: Six cases of post-extraction bleeding due to local and systemic factors with different etiologies were presented, followed by a literature review to further discuss the diagnosis and management of bleeding. Conclusions: Bleeding after tooth extraction requires a careful history and evaluation in establish-ing a diagnosis with appropriate management to avoid more serious bleeding complications.
The effect of photocatalyst effect of titanium dioxide anatase on heat polymerized acrylic resin plate towards the growth of Candida albicans colonies
Authors: Widodo Teguh Tri , Ayu M Claudia Sekar
Published: April 2022

Background: In general, removable denture are made from polymethyl methacrylate (PMMA) resin as the base material. This material has a drawback, namely that it is often attached to micro-organisms such as the fungus Candida albicans. Nanoparticle materials such as titanium dioxide (TiO₂) have antimicrobial properties, especially against C.albicans because it has photocata-lytic properties that can inhibit the growth of C.albicans colonies. Objective: To determine the effect of applying titanium di-oxide to heat polymerized acrylic resin (HPAR) plates towards the growth of C.albicans colonies. Methods: A true experimen-tal laboratory study using the HPAR plate as the object of research which was divided into the control group and the 1%, 2%, and 3% titanium dioxide-added groups. Data were analyzed using one-way Anova Welch. Results: There was an effect of add-ing titanium dioxide on the base of HPAR RD towards the growth of C.albicans colonies. Statistical tests showed significant re-sults (p=0.000; <0.05)). In the test between the titanium dioxide 1%, 2%3% and control groups, there were significant diffe-rences. Conclusion: The application of titanium dioxide to the base of HPAR RD reduced the growth of C.albicans colonies.

Published: April 2022

The nominal species name “ Theodoxus dniestroviensis ” was commonly accepted as introduced by Put’ in 1972 for neritid snails occurring in the upper part of the Dniester River basin. Currently an earlier publication [Put’, 1957] has been found in which this name is established in accordance with the ICZN guidelines, so the dating should be amended to Put’, 1957.The type series of Theodoxus dniestroviensis is apparently lost but the samples from the type locality were recently traced in the National Museum of Natural History of the National Academy of Sciences of Ukraine (Kiev). An illustrated comparison of topotypic specimens with other morphotypes of regional river nerites is provided. Given the variation in conchological characteristics observed among the specimens of Th. fluviatilis , we consider Th. dniestroviensis to range within its intraspecific variability. This makes Th. dniestroviensis a junior subjective synonym of Theodoxus fluviatilis (Linnaeus, 1758).
