Purpose:
The aim of this study was to identify, compile, and report the technical specifications of current and historical intraoral digital radiographic systems and recommend standardised reporting practices for production companies.
Materials and Methods:
A comprehensive report was prepared on 150 intraoral digital radiographic systems, comprising 105 sensor-based (70%) and 45 phosphor storage plate (PSP)-based systems (30%). Technical specifi cations were obtained from official company sources and scientific articles to ensure a complete collection of available data.
Results:
These systems were produced by 55 companies across 11 countries, with the United States leading (35.3%), followed by France (12%). Among the sensor systems, 76.2% used complementary metal-oxide-semiconductor (CMOS) technology, with notable variations in sizes and resolutions. PSP systems were available in 7 plate sizes and displayed diverse resolutions and scanning times. Twenty-one companies produced both sensor- and PSP-based systems, 33 produced only sensor-based systems, and 1 produced exclusively PSP-based systems.
Conclusion
This report identified 150 digital radiographic systems, revealing wide variability in technicalspecifications and a lack of standardised reporting protocols. The comprehensive summary and recommendations forconsistent documentation provided here can help clinicians make informed decisions and encourage manufacturers and production companies to adopt uniform reporting standards aligned with local regulatory frameworks.

Purpose:
The objective of this study was to evaluate variations in entrance skin dose across different anatomical regions of a head phantom and to present entrance skin dose results obtained from a limited number of measurement points. By identifying key anatomical landmarks, the study aims to rationalize the number of entrance skin dose measurement points using thermoluminescence dosimeters (TLDs).
Materials and Methods:
A tissue-equivalent head and neck phantom was examined with a 1-shot cephalometric X-ray machine under standardized settings. A detailed measurement protocol (140 TLDs for protocol 1) was compared to 3 alternative protocols using fewer measurement points (40 TLDs for protocol 2, 30 TLDs for protocol 3, and 6 TLDs for protocol 4).
Results:
Protocol 1 yielded an average entrance skin dose of 1.042 mSv, with higher doses at the parotid gland and above the left eye corner. Protocols 2 and 3 produced similar mean doses (1.003 mSv and 1.04 mSv, respectively), demonstrating that fewer dosimeters can still generate reliable results. Protocol 4, which targeted radiosensitive sites such as the thyroid and parotid glands, provided a comparable mean entrance skin dose for the beam-facing side (1.76 mSv) relative to the other protocols.
Conclusion
These findings suggest that the selected dosimetry approach is effective in assessing exposure to keytissues such as the skin. The results provide a foundation for a more representative, reproducible, and cost-effective dosimetric method in cephalometric radiography.
