Survival of Prosthodontic Restorations Luted with Resin-Based versus Composite-Based Cements: Retrospective Cohort Study

The purpose of this study was to evaluate clinical performance, survival, and complications of indirect composite inlays, onlays, and overlays on posterior teeth. Digital records of 282 patients treated between 2014 and 2018 were accessed and analyzed retrospectively. The included patients received 469 composite restorations luted with seven different resin-based types of cement, i.e., Filtek Ultimate Flow, Enamel Plus, Relyx Ultimate, Harvard Premium Flow, Relyx Unicem, Filtek Bulk Fill Flowable, and Filtek Ultimate. The restorations had been clinically and radiographically evaluated annually. The mechanical and clinical complications, e.g., debonding, fracture, and secondary caries, were evaluated and recorded. The examined restorations exhibited a high survival rate (84.9%), and failure was found in only 71 cases. Fracture was the most common cause (n = 36), followed by prosthetic work release (n = 19) and secondary caries (n = 16). There was a statistically significant difference between failure and cement material (Sig. < 0.001); the composite-based cements (87.2%) had a high survival rate compared to the resin-based cement (72.7%). Similarly, the cements with high viscosity (90.2%) had significantly higher survival rates than the low-viscosity cements (78.9%). Moreover, onlays showed higher longevity compared to overlays (Sig. = 0.007), and patients aged under 55 years showed less complications (Sig. = 0.036). Indirect composite restoration was a successful solution to tooth structure loss. The material of the cementation is an important part of the success. Higher survival rate was found in our study when the fixation materials with high viscosity were used, thus suggesting using these materials with indirect restorations. Composite-based cements had significantly higher survival rate than resin-based cements.

ABSTRACT ORAL CANCER SURGERY WITH RECONSTRUCTION DEFECTS BY SUBMENTAL FLAP Introduction: Globally, oral cancer accounts for 30% of head and neck cancers and 2.0% of all cancer. The surgery must remove the tumor with safe marginal resection to limit recurrence; however, it causes large defects. The submental flap is gaining popularity as a technique for reconstructing oral defects, with advantages: high survival rate and flexibility. This study aimsto evaluate the efficacy of the submental flap in reconstructive defects after oral cancer surgery at the Department of Oncology Surgery - Oncology Center of Hue Central Hospital from April 2020 to August 2021. Methods: A prospective study was conducted on 8 patients who had defects reconstructed by a submental flap after oral cancer surgery. Results: The average dimension of the submental flap was 28 cm2 (4 x 7 cm). The reconstructed sites included: tongue (3 cases), floor of mouth (4 cases), buccal mucosa (1 case). Patients had oral feeds after 8 days, discharged after 12 days. Complications: Oro - cutaneous fistula (2 cases), partial necrosis (1 case). After one month, the flaps were survival, and the oral cavity function had reduced (swallowing and speech function were quite limited). After six months, 7/8 cases had no locoregional recurrence; the flap was good, and the oral cavity function was normal. One case had local recurrence. Conclusions: Submental flap is a valid option for reconstructing intra - oral soft tissue with a high survival rate. Keywords: Oral cancer, submental flap.

TEST RESULTS OF STARTING COMPOUND FEEDS FOR INDUSTRIAL CULTIVATION OF SALMONIDS (CHUM SALMON)

The analysis of data on the conduct of fish-biological tests for the period 2016-2020 is presented at fish breeding plants of Primorsky and Khabarovsk territories on juveniles of chum salmon experimental granulated and extruded starter feeds, both with the use (compound feed V1M) and without the use of fermentolysate (compound feed V1M-BF). The highest average daily gains, as well as the average final weight of juveniles, were noted when dry fermentolysate was used as part of the starting compound feed. This is consistent with the data available in the literature on the positive effect of the products of partial protein fermentolysis at the initial stages of salmon development. When carrying out biological experiments, there is a high survival rate of fry from 97.5 to 99.9%, a low feed ratio for granulated feed with dry fermentolysate (0,64-0,80) and a protein utilization ratio (0,25-0,35).

Anti-Mullerian Hormone And Puberty Development On Girls And Adolescents Who Underwent Cancer Treatment

Background: High survival rate of children diagnosed with cancer has led to a growing population of women with premature ovarian failure (POF) due to chemotherapy and radiotherapy. The POF process occurs due to the disruption of the Hypothalamic-Pituitary and gonadal axis followed by the delay of puberty development. Evaluation of reproductive function in children with cancer is essential to determine the fertility preservation plan. This study aimed to describe reproductive function in children and adolescents with cancer who received chemotherapy based on Tanner stage evaluation, menstrual cycle, and Anti-Mullerian Hormone (AMH) examination using Electrochemilumiscence Immunoassay (ECLIA) Kit.Result: Twenty-three girls aged 12-18 years old and had menarche who underwent cancer therapy in January-August 2019 in Dr. Sardjito General Hospital were included in the study. Among them, 61% girls had low AMH levels and were defined as Diminished Ovarian Reserve (DOR). There were two subjects with DOR who experienced delayed puberty. Regular menstrual cycle was reported in 65.2% subjects, while 21.7% encountered secondary amenorrhea.Conclusion: Chemotherapy exposure impacted on DOR occurrence in 60.9% childhood and adolescence cancer. Moreover, it also altered menstrual regularity in 34.8% and delayed on puberty development in 8.7% subjects.

The Growth of Seriatopora hystrix (Dana, 1846) Transplant with Differences of Fragments Size and Planting Position

Transplantation of coral reefs requires sufficient fragments but must still ensure the sustainability of coral donors. This research aimed to know the survival rate and growth rate of transplant corals with different fragment sizes and planting positions and to determine the most effective and efficient transplantation methods of the Seriatopora hystrix. The research was conducted from January to April 2016 in Serangan Island waters Denpasar Bali (1-2 m depth). The method used was a field experiment with variations of planting position (vertical, horizontal) and fragment sizes (3, 5, 7 cm). The results showed a high survival rate (98.3%) of the transplanted S. hystrix with planting position and fragment sizes variation. The variation of planting position and fragment sizes were significantly affected the length growth rate of the S. hystrix (p <0.05). The vertical planting position showed better growth compared to the horizontal planting position. The transplantation of coral with initial fragment sizes of 5 and 7 cm showed a higher growth rate than the fragment size of 3 cm. However, statistical analysis revealed no significant difference between initial fragment sizes of 5 and 7 cm. Therefore, this study demonstrated the most effective and efficient for S. hystrix transplantation showed in the vertical position with the initial fragment size of 5 cm.Key words: coral bleaching, initial fragment, tropical, zooxanthellae

Effect of Root Trainer on the Success of Grafting and the Survival Rate of Cashew Tree [Anacardium occidentale L.(Anacardiaceae)] in Field

Grafting is the most widespread vegetative propagation technique in cashew tree (Anacardium occidentale L.). Usually, cashew plant grafting are done on seedlings in plastic bags in nursery. In addition, to the low success rate, grafted plants have a low viability rate in field because main roots were broken during their transfer to the field. This study was carried out to evaluate the grafting success and survival rate of cashew seedlings planted in root trainer with different size (250 cc, 500 cc and 1000 cc). Each type of container was filled with two different growing substrates: coconut fiber and sawdust. Results showed that large size root trainers (1000 cc) have the highest percentage of graft success (96.67%). Rootstocks 45 days old presented the highest percentage of graft success in nursery (94.31%). The longest scions (12 cm) presented the minimum sprouting time (18.21 days). In the field, survival rate 100% of the grafted plants was recorded. In addition to the high survival rate ensured in field, root trainer is eco-friendly reusable and it light nature can prove a profitable technology for raising cashew elite plants regeneration.

The Effects of Different Natural Anesthesia on Survival of Juvenile Sang kuriang Catfish (Clarias gariepinus) on Closed Wet System Transportation

This research aims to understand the effect of the different natural anesthesia on the survival rate of sangkuriang catfish juvenile which was transported using closed wet system fish transportation. We discussed selected natural anesthesia for effectiveness, induction times and recovery times in the application of anesthesia for transportation. The benefits of this research were as a reference to choose the best natural anesthesia for catfish juvenile transportation. This research used the experimental method on Completely Randomized Design (CRD) with 4 treatments (clove oil, nutmeg oil, lemongrass oil, and control) with 3 replications. Measured parameters were survival rate after fish transportation, survival rate after aquaculture for 7 days, induction times, recovery times,and water quality such as temperature, dissolved oxygen (DO), pH, and ammonia. The result was clove oil had high survival rate after fish transportation and cultivated for 7 days which is 98,67% and 87,33%. This treatment had quicker time for induction of catfish juvenile than other treatments which was 12.59 minutes although recovery time (10.34) minute was assumed lower than other treatments.

Diseminasi Teknik Budikdamber Lele untuk Produksi Pangan Skala Rumah Tangga Selama Pandemi Covid-19

CATFISH MINICULTURE OFTEN CALLED AS “BUDIKDAMBER” HAS RAPIDLY GAINED ITS POPULARITY DURING COVID-19 PANDEMIC DUE TO FOLLOWING REASONS: EASY TO ADOPT AND AFFORDABLE. In this regard, we disseminated technical assistance of “budikdamber” to villagers in two villages: Montongsekar and Sugihwaras, which aimed at fostering the food production in households. The dissemination was carried out through three activities: (1) assembly of “budikdamber” unit, (2) assistance and observation, and (3) evaluation. The unit was assembled using 80 L-plastic container, and filled with about 60 L of freshwater. Catfish seeds (12 cm in length) were reared in the unit for 3 weeks. During the period, their growth (body length, in cm) and survival rate. At the end of period, questionnaires were asked to the participants. The results showed that “budikdamber” unit could be made simply, equipped with water outlet, allowing to change water without jeopardizing fish survival. The assistance and observation to the participants demonstrated a pivotal role in disseminating the technical aspects of the catfish miniculture. The aquculture of catfish using “budikdamber” resulted in a satisfying output, represented by high survival rate ranging from 94 - 100% and final fish size (16.82 - 17.90 cm ). For further consideration, we need to publicize the fish culture method using both offline and online approaches, enabling to deliver the benefits of this technique to broader scale. In conclusion, “budikdamber” could impose significant effect on our attempts in ensuring food security during covid-19 pandemic.

The effect of density on the cultivation of the native mangrove oyster Crassostrea tulipa (Lamarck, 1819)

In Brazil, the cultivation of Crassostrea tulipa (= C. gasar) is gaining in importance. However, little is known about the best conditions for farming. Therefore, this study aimed to evaluate the effect of oyster density (50, 100, 200, and 400 mL of seeds/0.15 m2; 100, 200, 300, and 400 ind/0.10 m2 (basket area) and 30, 60, 120, and 180 ind/0.13 m2 (lantern floor area) in nursey, juvenile and adult phase, respectively) on the growth and survival of C. tulipa in farm cultivation. In the nursery phase, the 50 mL density resulted in smaller oyster size, as expressed in height and height/length (H/L) ratio (1.31 ± 0.03 mm), compared to other densities, while the length and width was equal among densities. The animals' individual average weight and H/L ratio were negatively influenced by a density of 100 ind/0.10 m2 or bigger. However, animals grown at the density of 200 ind/0.10 m2 did not differ statistically in length or width from those grown with 100 ind/0.10 m2. A high survival rate (≥98%) was found in the nursery and juvenile phases.
