Dental researchers, healthcare quality teams, and practice leaders need more than complaint counts to understand why patients lose trust. The 2026 PLoS One study by Lorraine Snyman, Thomas Corne Postma, and Werdie Van Staden shows how qualitative analysis of dental complaints can reveal the meanings behind dissatisfaction, safety concerns, and relationship breakdowns. This article summarizes the study's four themes and explains how AI-enabled qualitative research can help teams analyze complaint narratives more consistently. The goal is not to replace researcher judgment, but to reduce manual synthesis time while preserving patient language, context, and ethical interpretation.
Key Takeaways
According to Patient complaints in dentistry: A qualitative meta-synthesis, published on November 12, 2026, qualitative evidence from 19 studies grouped dental complaints into four connected domains: impeded access, unsatisfactory communication and attitudes, deficient clinical treatment, and unethical or unprofessional conduct.
The study concludes that dental complaints can signal breakdowns in trust, patient agency, relational security, and professional obligations, making qualitative analysis valuable for healthcare improvement beyond counting complaint types.
- The researchers identified 857 records in searches conducted through September 2024 and updated on August 26, 2026; 19 studies ultimately met the inclusion criteria.
- According to the 2026 PLoS One study, deficient clinical treatment appeared in all 19 included studies, representing 100% of the qualitative evidence base.
- According to the same study, unethical and unprofessional conduct appeared in 17 of 19 studies, or 89% of the included evidence, while all four themes appeared together in 11 studies.
- The researchers used reflexive thematic analysis after screening findings from studies across online reviews, regulatory complaints, litigation claims, and other dental care settings.
- The study cautions that the synthesis is interpretive rather than population-level, because qualitative meta-synthesis explains shared meanings rather than estimating complaint prevalence.
How Qualitative Analysis of Dental Complaints Works
The 2026 PLoS One study analyzed qualitative findings from previously published research rather than treating complaint counts as a complete account of patient experience. The authors searched MEDLINE, PsycINFO, PubMed, Scopus, Web of Science, and CINAHL, then used the Sandelowski and Barroso six-step approach to qualitative meta-synthesis.
The study treated the included literature as a higher-order case and each included article as an embedded subcase. The researchers coded qualitative findings from study results sections, including patient quotations and author-interpreted themes, while excluding descriptive statistics and quantitative complaint categories from inductive coding.
The authors combined semantic coding, which captured what patients explicitly described, with latent coding, which interpreted underlying relational and ethical meanings. For example, scheduling difficulties, long waits, and limited responsiveness were synthesized into the broader concern of impeded access to care.
One patient quoted in the 2026 PLoS One study described the access problem directly: "...give you a number to call...and you never get through... I tried to make an appointment, phone kept ringing out." A second patient summarized a communication failure as follows: "I have to ask a lot to get to know what I have to do."
The study's method shows why qualitative research matters for complaint management: the same surface issue, such as a delayed appointment or treatment problem, may represent a deeper concern about respect, autonomy, safety, or trust.

What the Four Dental Complaint Themes Mean for Healthcare Teams
How does impeded access to care appear in dental complaints?
Impeded access to care appears through complaints about availability, appointment scheduling, waiting times, inaccessible premises, and treatment cost, according to the 2026 PLoS One synthesis.
The study interprets these complaints as possible signals that patients feel their time, needs, or ability to obtain care are not being valued. Healthcare teams can therefore code administrative complaints alongside financial and geographic barriers rather than treating them as unrelated service issues.
Why does communication matter in qualitative dental research?
Communication matters because patients in the 2026 PLoS One synthesis connected dissatisfaction with limited explanations, technical language, poor listening, weak empathy, and disrespectful interactions.
The study suggests that communication failures can reduce patient agency and trust even when a complaint also involves a clinical outcome. Researchers should preserve patient wording and interactional context when analyzing these narratives.
What did the study find about deficient clinical treatment?
Deficient clinical treatment was the most widespread theme, appearing in all 19 studies included in the 2026 PLoS One meta-synthesis.
Patients described poor treatment quality, pain, repeated visits, inadequate aftercare, safety concerns, and treatment outcomes that did not meet expectations. The authors emphasize that clinical problems often intersect with communication, consent, and continuity-of-care concerns.
How did patients describe unethical or unprofessional conduct?
Patients described unethical or unprofessional conduct through concerns about informed consent, undisclosed risks, dishonesty, discrimination, poor accountability, unsafe practice, fraud, and negligence, according to the 2026 PLoS One study.
The theme appeared in 17 of 19 included studies. The authors interpret these complaints as threats to professional integrity and the fiduciary patient-practitioner relationship.
How Evidano Helps With AI-Enabled Dental Complaint Analysis
Problem: Complaint narratives are difficult to synthesize at scale
Evidano is an AI-powered qualitative data analysis platform that helps researchers analyze interviews, open-ended surveys, documents, and patient narratives.
Researchers can upload complaint documents and use thematic, content, frequency, and cross-segment analyses to identify recurring concerns such as access, communication, clinical treatment, and professional conduct. Teams can review the evidence behind themes instead of relying only on automated summaries.
Problem: Themes can hide differences between complaint sources
Solution: Compare complaint sources and patient segments with cross-segment analysis. The 2026 PLoS One study found that online complaints, regulatory complaints, and litigation or malpractice claims did not always emphasize the same domains.
Evidano can help teams compare themes across source type, clinic, patient group, treatment context, or time period. Researchers can use these comparisons to distinguish broad patterns from context-specific concerns.
Problem: Researchers need to interrogate evidence behind a theme
Solution: Use AI chat over uploaded documents and analyses to ask focused questions about supporting excerpts, contrasting cases, and theme boundaries. This can help researchers move from an initial code such as scheduling failure to a more interpretive question about responsiveness, trust, or patient agency.
Researchers should validate AI-generated codes and interpretations against the original patient narratives, especially when complaints involve safety, consent, discrimination, or professional misconduct.
Problem: Healthcare data requires careful handling
Solution: Use transcription with PII redaction and Evidano's data-security controls when complaint research includes audio or identifiable patient information. Evidano states that uploaded data is encrypted and is never used to train third-party models.
Healthcare teams should still follow applicable ethics approvals, consent requirements, retention policies, and institutional data-governance rules. Qualitative analysis is research-focused and does not provide clinical diagnosis or legal determinations.
