Study finds major gaps in electronic dental record systems
A 2020 assessment of dental clinics in Tehran found that many clinical data fields and software functions were missing.

The cross-sectional study examined what information electronic dental record systems contained and what functions they offered. The researchers compared the systems with data elements and features proposed by dental, health-information, and software-certification organizations, using descriptive statistics to summarize the results.
The systems consistently included some administrative and basic medical information, but many clinical items were missing. The researchers reported that the systems functioned mainly as administrative and information-recording tools rather than as comprehensive clinical systems, although this assessment did not establish how the gaps affected patients or dental treatment.
What the study looked at
The researchers examined the content and features of electronic dental record systems used in dental clinics in Tehran, Iran. The abstract reports that 22 clinics were assessed in 2020. The methods describe direct observation by one trained health-information technology researcher, including visits to 60 clinics and observation of clinics with an electronic dental record system; the relationship between the 60 visits and the 22 clinics reported in the abstract is not fully clear. The researchers created checklists from standards or models associated with the American Society for Testing and Materials, the American Dental Association, the University of Pittsburgh, Health Level Seven, the Healthcare Information and Management Systems Society, and the Certification Commission for Healthcare Information Technology. Six faculty members reviewed the checklist content, and the final items used yes-or-no assessments.
What researchers observed
Across the systems, 219 data elements were identified. Twenty-three were supported in every system, and the medical-care category was the only category in which all listed elements were fully included. Fifty-five data elements were absent from every system, including all elements in the categories of contact with hazardous substances, diagnostic tests, extraoral examination, and risk assessment.
Of 74 software features assessed, 11 were present in every system and 22 were absent from every system. The absent features included all features related to drug administration and support for treatment plans, guidelines, and protocols. The researchers also reported no clinical decision-support features in the systems they assessed. These are descriptions of the evaluated systems, not evidence that the systems caused harm or that adding features would improve patient outcomes.
Who this is relevant to
The findings apply most directly to the electronic dental record systems assessed in dental clinics in Tehran and may be informative for settings with similar software and resources. They should not be assumed to describe all dental record systems in Iran or other countries. Because the study did not examine patients or health outcomes, it does not establish how these findings apply to individual patients, dentists' clinical decisions, or the safety or effectiveness of dental care.
Why it matters
Electronic dental records can contain both administrative information and clinical information used in dental care. This study indicates that the systems examined in these Tehran clinics had substantial gaps in standardized clinical data and software functions. The findings may help describe health-information infrastructure in similar settings, but they do not show whether the missing items led to errors, poorer care, or worse health outcomes, and they do not establish that proposed system upgrades would improve care.
Limitations & evidence assessment
The study was cross-sectional and descriptive, so it provides a snapshot of systems in 2020 and cannot show changes over time or cause-and-effect relationships. It assessed clinics in one city and included a limited number of systems, so the findings may not represent dental clinics elsewhere. The study evaluated whether predefined data elements and features were present, but it did not report patient outcomes, clinical performance, usability, data accuracy, or the effects of missing features on treatment. The methods mention visits to 60 clinics, while the abstract reports 22 clinics assessed, and the available information does not fully explain this difference. The checklist was based on selected standards and expert review, so other relevant data elements or functions may not have been included.
Why this evidence level: This was a descriptive, cross-sectional assessment of electronic dental record systems in clinics, not a clinical study of patients or health outcomes. It involved a limited number of clinics in one city and did not test whether system features improve care.

This systematic review examined randomized human trials of concurrent chemotherapy and radiation for locally advanced head and neck, cervical, esophageal, and non-small-cell lung cancers. Across the included trials, combined treatment was reported to provide better overall survival than radiation alone, but it also caused more severe short-term side effects. The review did not provide enough information in its abstract to show how many trials or patients were included.
Researchers pooled results from seven human studies comparing multiple-staged with single-stage removal and reconstruction of congenital melanocytic nevi, sometimes called congenital moles. Staged surgery was associated with fewer major wound complications and recurrences, as well as slightly shorter and narrower scars, but the studies did not find a clear difference in cosmetic or overall patient satisfaction.
A cluster-randomized human study in 210 adults with recently detected stage 1 hypertension in Uzbekistan compared salt-sensitivity testing followed by assigned medication choices with conventional management. After 12 weeks, more participants in the testing-guided group reached the study's blood pressure target, although the study was small, short, and conducted in only three primary care centers.
