Academic session 2026-2027  · 100 topics

This page lists 100 periodontology thesis topics for Master of Dental Surgery postgraduate students for the 2026-2027 academic session. The topics are structured around practical dissertation questions that can be adapted to the clinical workload, imaging facilities, laboratory support, materials and records available in a dental teaching institution.

The periodontology thesis topics below cover periodontal disease, systemic associations, gingival phenotype, radiographic bone loss, biomarkers, oral hygiene, behavioural factors, peri-implant diseases, microbiology and contemporary periodontal practice. They include cross-sectional, observational, comparative, imaging-based, record-based and in-vitro approaches so that students can select a research question that matches their departmental resources while retaining a clearly measurable primary outcome.

Choosing a Periodontology thesis topic

How should I choose a feasible Periodontology thesis topic?

Start with the cases, records, imaging facilities, laboratory methods and materials that are consistently available in your department. A feasible periodontal thesis should have a clearly defined primary outcome and should not depend on expensive equipment or rare patients unless access is already assured. Before finalizing the protocol, review recent departmental case numbers, identify the variables that can be measured reliably, and decide whether the proposed comparison groups are realistically available. A focused question with adequate numbers is usually stronger than a technically ambitious project that cannot recruit or complete its planned measurements.

Which study designs are practical for an MDS thesis in Periodontology?

Cross-sectional, comparative cross-sectional, retrospective record-based, imaging-based and in-vitro designs are often practical for an MDS dissertation because they can be completed within a defined academic period. The best design depends on the research question and available resources. Clinical prevalence or association questions generally suit cross-sectional methods, existing case records can support retrospective studies, and material or technique comparisons may suit controlled in-vitro work. The protocol should specify the sampling method, primary variable, measurement technique and statistical comparison in advance rather than selecting a design solely because it appears easy to conduct.

What should be checked before finalizing a Periodontology dissertation protocol?

Confirm that the department can provide enough eligible observations during the proposed study period and that every major variable can be measured using a standardized method. For imaging or record-based work, review a small sample of existing records to assess completeness and consistency. For in-vitro projects, verify availability of specimens, materials, equipment and the testing method before calculating the sample size. The final protocol should clearly separate the primary objective from secondary objectives, define inclusion and exclusion criteria, identify potential confounders where relevant, and use outcomes that directly answer the stated research question.

Thesis and protocol questions

How is a thesis topic different from a thesis protocol?

The topic is the title — the question a study sets out to answer, together with the population and the design. The protocol is the full document built around it: background, review of literature, aims and objectives, inclusion and exclusion criteria, sample size calculation, methodology, statistical plan, ethics considerations, consent documents and references. A topic is agreed with a guide first; the protocol is written afterwards and submitted to the institutional ethics committee.

When does a postgraduate thesis have to be submitted?

For most Indian postgraduate programmes the protocol is submitted within the first six months of joining, and the completed thesis is submitted at least six months before the final examination. Exact deadlines are set by the university, so the departmental circular for the current session takes precedence over any general timeline.

How is sample size decided for a postgraduate thesis?

Sample size follows from the primary objective, not the other way round. A prevalence study is powered from an expected proportion and an acceptable margin of error; a comparative study is powered from the expected difference between groups, the standard deviation, alpha and desired power. The figure should then be checked against the institution's actual case load for the study period, because a statistically ideal sample that cannot be recruited in the time available is not a workable plan.

Does a thesis topic need ethics committee approval?

Yes. Every postgraduate thesis involving human participants, human data or human samples requires clearance from the institutional ethics committee before data collection begins. Approval is granted on the protocol rather than on the title, and the submission usually includes the protocol, the participant information sheet and the consent form in English and in the local language.

What makes a topic realistic for a three-year postgraduate programme?

A workable topic can be completed at a single centre, with equipment and investigations that are already available in routine practice, within roughly eighteen months of data collection. Topics that depend on external funding, specialised assays, multicentre coordination or long follow-up tend to stall. Choosing a condition the department already sees in volume matters more than choosing a novel one.

Can a thesis be published as a research paper afterwards?

Yes, and it is generally expected. A thesis is usually condensed into a paper of around three to four thousand words, restructured into the standard introduction, methods, results and discussion format, with the review of literature shortened considerably. Journals differ in their requirements, and the ethics approval number from the original thesis is normally cited in the methods section.
