Dental service utilization trends in rural and semiurban health centers of Isfahan, Iran (2016-2021): A retrospective descriptive study.
Article in Dental research journal, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Background: Iran's oral health reform plan aimed to shift primary dental care toward prevention through the family dentist program, yet longitudinal evidence on real-world service mix is limited. We assessed 6-year trends in dental service utilization in rural and semiurban primary healthcare facilities in Isfahan, Iran. Materials and Methods: This retrospective, longitudinal, observational, descriptive study analyzed aggregated service counts extracted from Iran's integrated health system (SIB) for two healthcare networks in Isfahan from 2016 to 2021. We included Level 2 clinical procedures recorded under the family dentist program and categorized them as preventive (fluoride varnish, fissure sealants, and scaling) or curative/treatment (restorations, extractions, and pulpotomy). Trends were summarized using annual volumes, year-to-year percentage change, and the proportional share of preventive versus curative services. Data were analyzed using descriptive statistics; no inferential statistical tests were applied, and a significance threshold was not defined, given the descriptive nature of the study. Results: A total of 133,075 Level 2 dental services were delivered over the study period. Utilization peaked in 2017 (28,290 services) and remained high in 2019 (28,027), suggesting a period of increased throughput during the implementation and maturation of the oral health reform package in primary health care, followed by a sharp decline in 2020 (11,215; -60.0% vs. 2019) and partial recovery in 2021 (20,691; +84.5% vs. 2020). Preventive share dropped to 7.2% in 2017, increased to 21.0% by 2019, and remained near 19% in 2020-2021. Health Center No. 2 delivered a higher cumulative volume than No. 1 (76,697 vs. 56,378 services). Permanent tooth extractions were the most frequent procedure (66,152), exceeding the total number of restorations (28,160). Conclusion: Despite a stable preventive component in later years and postpandemic recovery, service delivery remained strongly treatment- and extraction-oriented, indicating a limited shift toward prevention within the primary care dental package.
