Dental composites' dependence on pricey imported components often raises price concerns and restricts accessibility in restorative dentistry. In Pakistan, using locally produced materials presents a viable alternative for more affordable and environmentally friendly dental treatments. This study aimed to develop and evaluate dental composites sourced from locally available materials in Pakistan for cost-effectiveness, performance, and durability.
A study comprising 385 patients, aged 18-65 years, who underwent composite restorations made of novel materials, was carried out at Sardar Begum Dental College, Peshawar, from January 2023 to December 2023. Patient comfort, aesthetic quality, and durability were the three main criteria used to assess clinical performance. The physical characteristics of adhesion strength, wear resistance, and hardness were evaluated in lab settings. Costs for materials, processing, and clinical application were all considered in a thorough cost study. SPSS version 26 (Armonk, NY: IBM Corp.) was used for the statistical analysis, and both descriptive and inferential statistics were used. The novel composites were compared with standard materials using t-tests, and cost differences were assessed. A p-value of less than 0.05 was considered statistically significant.
The novel composites exhibited superior performance with a durability of 12.57 ± 1.83 months (n = 385 patients), compared to 11.05 ± 2.38 months for conventional composites (p < 0.05). They also scored higher in aesthetic quality (8.35 ± 1.48 vs. 7.82 ± 1.59) and patient comfort (4.52 ± 0.79 vs. 4.27 ± 0.83) (p < 0.05). Laboratory tests showed greater hardness (48.79 ± 3.22 Vickers), better wear resistance (0.28 ± 0.05 mm³), and higher adhesion strength (22.96 ± 1.68 MPa) (p < 0.05). Cost analysis revealed significant savings, with total costs per patient of PKR 8,980 for novel composites vs. PKR 33,000 for conventional composites (p < 0.05).
Novel dental composites developed from locally sourced materials demonstrate superior performance and significant cost reductions, highlighting their potential to enhance the accessibility and affordability of dental care in Pakistan.
牙科复合材料对昂贵进口成分的依赖常常引发价格担忧，并限制了修复牙科的可及性。在巴基斯坦，使用本地生产的材料为更经济实惠且环保的牙科治疗提供了一个可行的选择。本研究旨在开发并评估源自巴基斯坦本地可得材料的牙科复合材料的成本效益、性能和耐用性。
2023年1月至2023年12月，在白沙瓦的萨达尔·贝古姆牙科学院对385名年龄在18至65岁之间、接受了由新型材料制成的复合修复的患者进行了一项研究。患者舒适度、美学质量和耐用性是用于评估临床性能的三个主要标准。在实验室环境中评估了粘结强度、耐磨性和硬度等物理特性。在一项全面的成本研究中考虑了材料、加工和临床应用的成本。使用SPSS 26版（纽约州阿蒙克：IBM公司）进行统计分析，同时使用了描述性统计和推断性统计。使用t检验将新型复合材料与标准材料进行比较，并评估成本差异。p值小于0.05被认为具有统计学意义。
新型复合材料表现出卓越的性能，耐用性为12.57±1.83个月（n = 385名患者），而传统复合材料为11.05±2.38个月（p < 0.05）。它们在美学质量（8.35±1.48对7.82±1.59）和患者舒适度（4.52±0.79对4.27±0.83）方面也得分更高（p < 0.05）。实验室测试显示硬度更高（48.79±3.22维氏硬度）、耐磨性更好（0.28±0.05立方毫米）和粘结强度更高（22.96±1.68兆帕）（p < 0.05）。成本分析显示有显著节省，新型复合材料每位患者的总成本为8980巴基斯坦卢比，而传统复合材料为33000巴基斯坦卢比（p < 0.05）。
由本地采购材料开发的新型牙科复合材料表现出卓越的性能并显著降低了成本，凸显了它们在提高巴基斯坦牙科护理的可及性和可负担性方面的潜力。
