Research has offered many advances in the dentistry field and variable types of dental composites have been widely validated to be effectively used with many favorable outcomes. Among the differently reported composites, hybrid ones are the most commonly reported and used in clinical settings. However, the characteristics of these composites vary hugely based on the materials and the environmental factors that they might be potentially exposed to. In this literature review study, we have discussed the types and characteristics of the dental composites, elaborating the effect of different environmental factors on the degradation of the different composite materials. Our results indicate that dental composites are hugely affected by environmental factors as temperature, moisture, chemical reactions and impact blunt. Furthermore, enhancing the quality of the materials by using more flexible approaches might enhance their quality in achieving better outcomes. Moreover, research should be directed within this area to improve the functions of the dental composites and improve the quality of life for the corresponding patients. Composites based on nanotechnology seem promising. However, these are not adequately investigated, and further research is encouraged for adequate validation.

Abstract: Loss of natural teeth, whether it is replaced with artificial teeth or not, can affect the quality of life (QoL), especially in relation to oral health. This study was aimed to determine the differences in the QoL of elderly between denture wearers and non denture wearers. This was a literature review study. There were five literatures in this study; three literatures used the GOHAI questionnaire as a research instrument meanwhile the others used the OHIP-14 questionnaire. The results showed that the measuring instrument most widely used was GOHAI. Based on age, the QoL of denture wearers and non denture wearers became worse as they became older. Based on sex, the QoL of the non denture wearers was better in males than in females, albeit, there was no difference between sex among the denture wearers. In conclusion, the QoL of denture wearers was better than of non denture wearers. Moreover, the QoL of denture wearers was relatively good, meanwhile the QoL of non denture wearers was poor.Keywords: quality of life, elders, denture, tooth loss Abstrak: Kehilangan gigi asli yang digantikan dengan gigi tiruan maupun tidak, dapat meme-ngaruhi kualitas hidup, khususnya kualitas hidup terkait kesehatan gigi dan mulut. Penelitian ini bertujuan untuk mengetahui perbedaan kualitas hidup lansia pengguna dan bukan pengguna gigi tiruan. Jenis penelitian ialah studi pustaka. Total pustaka yang diteliti berjumlah lima buah. Terdapat tiga pustaka yang menggunakan kuesioner GOHAI sebagai instrumen penelitian, sedangkan dua lainnya menggunakan kuesioner OHIP-14. Hasil penelitian menunjukkan bahwa alat ukur yang paling banyak digunakan yaitu GOHAI. Berdasarkan usia, semakin bertambahnya usia, kualitas hidup lansia pengguna dan bukan pengguna gigi tiruan semakin buruk. Berdasarkan jenis kelamin, kualitas hidup lansia bukan pengguna gigi tiruan lebih baik pada laki-laki daripada perempuan, sedangkan pada lansia pengguna gigi tiruan, hasilnya seimbang. Simpulan penelitian ini ialah kualitas hidup lansia pengguna gigi tiruan lebih baik daripada bukan pengguna gigi tiruan. Kualitas hidup lansia pengguna gigi tiruan tergolong baik sedangkan kualitas hidup lansia bukan pengguna gigi tiruan tergolong buruk.Kata kunci: kualitas hidup, lansia, gigi tiruan, kehilangan gigi

Rotator cuff (RC) disease is a common musculoskeletal disorder of the shoulder entailing pain, with reduced functionality and quality of life. The main objective of this study was to present a perspective of the current scientific evidence about personalized, predictive, participatory, precision, and preventive approaches in the management of RC diseases. The personalized, predictive, participatory, precision and preventive (P5) medicine model is an interdisciplinary and multidisciplinary approach that will provide researchers and clinicians with a comprehensive patrimony of knowledge in the management of RC diseases. The ability to define genetic predispositions in conjunction with the evaluation of lifestyle and environmental factors may boost the tailoring of diagnosis and therapy in patients suffering from RC diseases.
