Abstract

Diabetes mellitus is a non-communicable disease that requires a long treatment so that patients have to take medication or visit the hospital more often, interest in repeat visits is a behavior that appears in response to objects that indicate a customer's desire to make a repeat purchase. The aim of the study was to find out whether the factors that determine interest in returning to diabetes mellitus patients at Pirngadi Hospital in Medan City in 2023. The research method uses a correlative descriptive design with a cross-sectional approach. The results showed that most of the respondents were male, namely 23 (51.1%), the education level of respondents who were high and medium had the same proportion, namely 18 (40%), the employment status of respondents was 30 (66.7%) working. Quality of service as many as 33 (73.3%) and as many as 28 (62.2%) families get high support. The results of the statistical chi-square test found that there was no significant relationship between gender and intention to revisit (p=0.155), there was no relationship between education and intention to revisit (p=0.371), there was no relationship between work and intention to revisit (p=0.828), there is a relationship between quality of service and interest in repeat visits (p=0.000). There is no relationship between family support and interest in repeat visits (p=0.000). This research is expected to be an evaluation material in improving health services related to the determinants of interest in repeat visits of patients with diabetes mellitus.

Abstract

Dental caries remains a significant global public health issue, particularly among school-aged children. A lack of knowledge regarding oral health maintenance is considered a primary contributing factor to the high prevalence and severity of caries in this demographic. This study aimed to analyze the influence of oral health maintenance knowledge on the severity of dental caries in Grade 6 students at SDN No. 060833. An analytical observational study with a cross-sectional design was conducted. A total of 39 students were selected using simple random sampling. Data on knowledge were collected using a validated questionnaire, while caries severity was assessed through direct oral examination and categorized as pit fissure caries, superficial caries, medium caries, or profound caries. Data analysis employed univariate and bivariate methods using the Chi-Square test. The majority of students (64.1%) had poor knowledge of oral health maintenance. The most common caries severity was superficial caries (35.9%), followed by medium caries (30.8%). Bivariate analysis revealed a statistically significant relationship between knowledge level and caries severity (p-value = 0.000). Students with poor knowledge were more likely to experience medium and profound caries. There is a significant influence of the level of knowledge about oral health maintenance on the severity of dental caries in Grade 6 students. Efforts to improve oral health knowledge through targeted education programs in schools are essential to prevent and reduce the severity of dental caries.

Abstract

Computer-Aided Design/Computer-Aided Manufacturing (CAD/CAM)-based 3D printing technology is widely used in the manufacture of denture bases due to its precision and efficiency. However, the quality of the printed results is greatly influenced by printing parameters, especially the exposure time per layer that plays a role in the polymerization process of photopolymer resin. This study aims to analyze the effect of exposure time per layer on the dimensional accuracy and flexural strength of denture bases fabricated using Open System 3D Printing technology. This laboratory experimental study used a post-test only control group design. Denture bases were printed using an open system with exposure time variations of 4.5, 5, and 5.5 seconds, and compared with Close System 3D Printing and heat-polymerized acrylic resin (RAPP). Dimensional accuracy was measured in length, width, and height parameters, while flexural strength was tested using the three-point bending test method. Statistical analysis was performed using Welch's ANOVA test and Tukey's extended test (α = 0.05). The results showed that exposure time per layer had a significant effect on dimensional accuracy and flexural strength (p = 0.000). In the open system, the highest length accuracy value was obtained at an exposure time of 5.5 seconds (64.99 ± 0.07 mm), followed by 4.5 seconds (64.98 ± 0.09 mm) and 5 seconds (64.94 ± 0.05 mm). The highest flexural strength value in the open system was obtained at an exposure time of 4.5 seconds (68.90 ± 1.27 MPa), followed by 5.5 seconds (67.29 ± 1.49 MPa) and 5 seconds (66.08 ± 2.32 MPa). The closed system group showed the highest flexural strength value (90.61 ± 2.72 MPa), while RAPP was 73.76 ± 3.60 MPa. It was concluded that the exposure time setting per layer plays an important role in optimizing the dimensional accuracy and mechanical properties of 3D printed denture bases

Abstract

Advances in additive manufacturing have enabled the fabrication of denture bases using three-dimensional (3D) printing technology; however, the mechanical properties of the resulting materials, particularly impact strength, are highly influenced by post-processing parameters such as curing time. This experimental laboratory study aimed to evaluate the effect of different curing time variations on the impact strength of 3D-printed denture base resin and to compare its performance with that of heat-polymerized acrylic resin (HPAR). A post-test only control group design was employed, in which specimens were divided into four groups consisting of 3D-printed resin with curing times of 4.5, 5.0, and 5.5 seconds, and a control group fabricated from HPAR. The results demonstrated that the 3D-printed resin cured for 5.0 seconds exhibited the highest mean impact strength (1.56 ± 0.14 kJ/m²), followed by the 4.5-second group (1.47 ± 0.09 kJ/m²), while the lowest value was observed in the 5.5-second curing group (1.28 ± 0.23 kJ/m²). In contrast, the HPAR group showed substantially higher impact strength than all 3D-printed resin groups, with a mean value of 2.99 ± 0.97 kJ/m². These findings indicate that curing time optimization significantly affects the impact strength of 3D-printed denture base resin; nevertheless, heat-polymerized acrylic resin remains superior in terms of mechanical toughness for denture base applications
