Dental diseases pose a significant health burden globally. Because of the increasing prevalence of dental caries and periodontal diseases, severe dental impairment has been reported in the developed and developing countries. Dental x-ray systems are useful in detecting and recording areas of decay that are undetectable by oral examination, especially minor areas of decay present between teeth. These devices are also used to detect periodontal diseases, as they help identify bone loss or any changes in bone structure or root canals due to infection. According to 2015 CDC statistics, 91% of the U.S. population aged 20–64 years reported dental caries. In addition, rising prevalence of periodontitis is also accelerating the demand for dental x-ray systems. According to NCBI 2017 data, around 20%– 50% of the global population is affected with periodontal diseases both in the developing and developed regions. Periodontal diseases are considered as a public health concern with rise in its prevalence among adolescents as well as adults.

Computer hardware spending contracted 2015-2017, with peso depreciation the main negative factor in 2015, but it was increasingly the cannibalisation of PC use cases by smartphones that was responsible for weak performance. Audio-visual spending growth resumed in 2017, supported by flat-panel TV set upgrades and replacements, as well as the positive trend for smartphone complimentary audio devices. After a slowdown in the smartphone boom in 2015 and 2016 as a result of challenging economic conditions the trend rebounded strongly in 2017 through upgrades and an extension of ownership to new users.

There was a sharp decline in device spending in 2016 as a result of depreciation and recession, which affected all three segments of the market, before a stabilisation in 2017 as economic conditions improved. The hardware trend was exhibiting a negative US dollar trend prior to 2016, and only recorded modest growth in 2017 with more supportive economic conditions because of shifting usage patterns. Handset spending outperformed again in 2017 as the smartphone boom resumed, based on a flow of first-time buyers and pent-up replacement demand from existing owners.
