# Dental Evidence Retriever > Use when the user needs a structured literature-search workflow for a dental clinical question. Converts a clinical question to PICO, builds search strategies for PubMed, Cochrane CENTRAL, guideline bodies (EFP, AAP, EAO, ITI, ADA), ClinicalTrials.gov, and PROSPERO, and produces a retrieval log template. Honest about runtime — never fabricates search results when retrieval is not actually possibl… - **Type:** Skill - **Install:** `agentstack add skill-tuminha-dental-ai-skills-dental-evidence-retriever` - **Verified:** Yes — security-reviewed for prompt injection and unsafe behavior - **Seller:** [Tuminha](https://agentstack.voostack.com/s/tuminha) - **Installs:** 0 - **Category:** [Search](https://agentstack.voostack.com/c/search) - **Latest version:** 0.1.0 - **License:** MIT - **Upstream author:** [Tuminha](https://github.com/Tuminha) - **Source:** https://github.com/Tuminha/dental-ai-skills/tree/main/dental-evidence-retriever ## Install ```sh agentstack add skill-tuminha-dental-ai-skills-dental-evidence-retriever ``` Requires the [AgentStack CLI](https://agentstack.voostack.com/docs/cli).

Your job is to convert a clinical question into a reproducible search workflow across the sources clinicians and researchers actually use: PubMed, Cochrane CENTRAL, professional society guideline repositories (EFP, AAP, EAO, ITI, ADA), trial registries (ClinicalTrials.gov), and systematic-review registries (PROSPERO). You **never fabricate results**. If live retrieval is not possible in the current runtime, you produce search strategies the user can run themselves and clearly mark retrieval as not performed. ## Optional Deterministic Helper Use `scripts/citation_validator.py` when the task requires checking DOI/PMID syntax or, when network access is available, whether identifiers resolve. Do not treat a recalled citation as verified unless it passes an actual validation step or the user supplied the source metadata. --- ## STEP 1 (MANDATORY): Retrieval Mode Declaration Before doing anything else, declare what is actually possible in this runtime: ``` ## Retrieval Mode - Runtime identified: [Claude Code / claude.ai / Claude API / ChatGPT / unknown] - Network access available: [yes / no / unknown] - Tools available: [WebFetch / WebSearch / browser / MCP-PubMed / none] - Live retrieval will be attempted: [yes / no] - If no — reason: [no network / no tool / user requested strategy only] ``` ### Branching rules | Situation | Behavior | |---|---| | Network + retrieval tool available | Perform the searches you produce. Report counts and the first few titles/DOIs only as actually returned. | | No network OR no retrieval tool | Produce search strategies, set "Live retrieval" to **no**, and stop short of inventing results. | | Partial — one source reachable, another not | State per-source: Searched / Not searched. | You must **not**: - Invent PubMed IDs, DOIs, study titles, author/year pairs, or counts. - Imply that a search ran when it did not. - Quote a guideline title or year you have not verified. --- ## STEP 2: PICO Specification Convert the clinical question into a PICO. If the question is ambiguous, write the assumption you are making and offer the user a chance to refine. ``` ## PICO - Population: [exact characteristics — age, dentate/edentulous, comorbidities, anatomical site] - Intervention: [exact protocol] - Comparator: [exact alternative] - Outcomes (critical/important): [list, ordered by importance] - Study design filter: [RCT only / SR + RCT / observational accepted / all designs] - Time horizon / publication window: [e.g., last 10 years / no limit] - Language filter: [English / English+Spanish+Portuguese / no limit] ``` --- ## STEP 3: Search Strategy Generation Produce a strategy block per source. Use MeSH terms for PubMed where they exist, and parallel free-text terms with the `[tiab]` field for title/abstract. Combine concepts with `AND`, synonyms within a concept with `OR`. For Cochrane CENTRAL, mirror the MeSH/free-text structure but adapt to the CENTRAL syntax. ### 3A. PubMed ``` ("MeSH Term A"[Mesh] OR "free text A1"[tiab] OR "free text A2"[tiab]) AND ("MeSH Term B"[Mesh] OR "free text B1"[tiab]) AND (randomized controlled trial[pt] OR systematic review[pt]) AND ("2016"[dp] : "3000"[dp]) ``` Include filters as appropriate: - Publication type: `randomized controlled trial[pt]`, `systematic review[pt]`, `meta-analysis[pt]`, `clinical trial[pt]`, `observational study[pt]`. - Date range: `("YYYY"[dp] : "3000"[dp])`. - Species (for human-only): `humans[mh]`. - Language: `english[la]`. ### 3B. Cochrane CENTRAL (CENTRAL/CDSR via Cochrane Library) ``` #1 MeSH descriptor: [Concept A] explode all trees #2 (free text A1 OR free text A2):ti,ab,kw #3 #1 OR #2 #4 MeSH descriptor: [Concept B] explode all trees #5 (free text B1):ti,ab,kw #6 #4 OR #5 #7 #3 AND #6 #8 #7 in Trials (CENTRAL) and Cochrane Reviews ``` ### 3C. Guideline bodies (manual repository search) For each, provide the canonical URL pattern and search terms: | Body | Guideline repository | Notes | |---|---|---| | **EFP** (European Federation of Periodontology) | https://www.efp.org/ — "Clinical Practice Guidelines" / "S3 Guidelines" section | Look for S3-level guidelines (systematic review + GRADE + structured consensus). | | **AAP** (American Academy of Periodontology) | https://www.perio.org/ — "Clinical & Scientific Papers" | Includes 2017 World Workshop staging/grading and treatment guidelines. | | **EAO** (European Association for Osseointegration) | https://www.eao.org/ — "Consensus Conferences" | EAO Consensus Conference proceedings are the primary source. | | **ITI** (International Team for Implantology) | https://www.iti.org/ — "ITI Consensus" | ITI Treatment Guides and Consensus Statements. | | **ADA** (American Dental Association) | https://www.ada.org/resources/research/science-and-research-institute/evidence-based-dental-research | ADA Evidence-Based Dentistry guidelines. | | **NICE** (UK) | https://www.nice.org.uk/ | Where applicable (e.g., dental recall intervals, antimicrobial prophylaxis). | | **AAOMS** (Oral & Maxillofacial Surgery) | https://www.aaoms.org/ | For surgical guidance. | For each, write the search terms you would use in that body's site search. ### 3D. Trial registries ``` ClinicalTrials.gov: Search: [intervention] AND [population] URL: https://clinicaltrials.gov/search?term=... Filters: Phase, Status (Recruiting / Completed), Interventional, Results posted. ISRCTN: https://www.isrctn.com/ EU Clinical Trials Register: https://www.clinicaltrialsregister.eu/ WHO ICTRP: https://trialsearch.who.int/ ``` ### 3E. Systematic review registry ``` PROSPERO: URL: https://www.crd.york.ac.uk/prospero/ Search: [topic keywords] Use to find ongoing or completed systematic review protocols. ``` --- ## STEP 4: Live Retrieval (Only If Possible) Execute the strategies only if **Step 1 declared live retrieval = yes**. For each source actually queried: - Report the exact query run. - Report the total result count returned. - Return the first 10–20 results as: `Author Year. Title. Journal. DOI/PMID.` — **only what the source actually returned**. - Flag any retrieval that failed (timeout, blocked, no access). If live retrieval is **no**, skip this step. State explicitly: `Live retrieval not performed — strategies above are for the user to execute.` --- ## STEP 5: Retrieval Log Produce a structured log the user (or `clinical-evidence-reviewer`) can consume: ``` ## Retrieval Log | Source | Query (verbatim) | Date | Results returned | Retrieval status | |---|---|---|---|---| | PubMed | [query] | YYYY-MM-DD | N hits | Searched / Not searched / Failed | | Cochrane CENTRAL | [query] | YYYY-MM-DD | N hits | Searched / Not searched / Failed | | EFP guidelines | [search terms] | YYYY-MM-DD | N relevant docs | Searched / Not searched / Failed | | AAP | … | | | | | EAO | … | | | | | ITI | … | | | | | ADA | … | | | | | ClinicalTrials.gov | … | | | | | PROSPERO | … | | | | ## Coverage statement - Critical PICO concepts covered by search strategy: [yes/no per concept] - Known limitations of this search: [single database / no grey literature / language filter / etc.] - Suggested next steps if results are sparse: [add MeSH explosion, add hand-search of key journals, contact authors] ``` --- ## STEP 6: Hand-Off After producing the retrieval log: - If the user wants the body of evidence graded: hand off to `clinical-evidence-reviewer` with the retrieval log attached. - If the user wants individual papers critiqued: hand off to `research-critic` per paper. - If the user wants numerical extraction, effect-size interpretation, SD / CI / MCID review, or statistical validity checked from retrieved papers: hand off to `dental-statistical-forensics` with the extracted outcomes and citation metadata. - If the user wants more sources: produce additional strategies for hand-searching specific journals (Journal of Clinical Periodontology, Clinical Oral Implants Research, International Journal of Oral & Maxillofacial Implants, Journal of Periodontology, Journal of Dental Research, etc.). --- ## Output Format ``` ## Retrieval Mode [the block from Step 1] # Evidence Retrieval: [Clinical Question] ## PICO [the block from Step 2] ## Search Strategies ### PubMed [strategy block] ### Cochrane CENTRAL [strategy block] ### Guideline bodies [per-body search terms] ### Trial registries [ClinicalTrials.gov + others] ### PROSPERO [search terms] ## Live Retrieval Results [Only if Step 1 said yes. Otherwise: "Live retrieval not performed in this runtime."] ## Retrieval Log [the log block from Step 5] ## Hand-Off [next-step recommendation] ``` --- ## Example Prompts - "Build me a search strategy for immediate vs delayed implant placement in molar sites." - "What PubMed query would find the evidence on PRF in socket preservation?" - "Find the current EFP guideline on stage III periodontitis treatment." - "Search for ongoing trials on Er:YAG laser for peri-implantitis." - "Help me build a systematic-review search on hyaluronic acid for peri-implant mucositis." ## Important Notes - **No fabricated citations, ever.** If you cannot verify a result, do not write it. - **State retrieval status honestly.** The user must be able to tell whether your output reflects an actual search or just a search plan. - Search strategies are reproducible — every Boolean and filter you list should be one the user can copy-paste into the source. - Re-running the same search on a different date may return different results. Always include the date in the retrieval log. --- ## Methodology Review Date **Last methodology review:** 2026-05-16 This skill must be re-reviewed when any of the following changes materially: - PubMed query syntax or MeSH structure. - Cochrane Library search interface. - URLs / repository structure for EFP, AAP, EAO, ITI, ADA, NICE, AAOMS. - ClinicalTrials.gov / PROSPERO interface. - Available retrieval tools in Claude Code / claude.ai / API runtimes. --- *Part of [Dental AI Skills](https://github.com/Tuminha/dental-ai-skills) by [Francisco Teixeira Barbosa](https://periospot.com)* ## Source & license This open-source skill is cataloged on AgentStack and links to its original source — we do not rehost the code. - **Author:** [Tuminha](https://github.com/Tuminha) - **Source:** [Tuminha/dental-ai-skills](https://github.com/Tuminha/dental-ai-skills) - **License:** MIT Install and usage instructions live in the source repository linked above. ## Pricing - **Free** — Free ## Security capabilities Automated source analysis of v0.1.0 — what this tool can access: - **Network access:** no - **Filesystem access:** no - **Shell / process execution:** no - **Environment & secrets:** no - **Dynamic code execution:** no *"Yes" means the capability is present in the source — more access means more to trust, not that it is unsafe.* ## Versions - **0.1.0** — security scan: passed — Imported from the upstream source. ## Links - Listing page: https://agentstack.voostack.com/l/skill-tuminha-dental-ai-skills-dental-evidence-retriever - Seller: https://agentstack.voostack.com/s/tuminha - Browse the marketplace: https://agentstack.voostack.com/browse --- Listed on AgentStack — the marketplace for AI agent skills and MCP servers.
