Effects of Antibiotic Prophylaxis on the Healing Parameters Following Surgical Crown Lengthening

A Phase 4 interventional study of Surgical crown lengthening and Augmentin in Tooth Diseases and Tooth Wear, sponsored by Biruni University. Not yet recruiting. Open to participants aged 18 Years and older, including healthy volunteers. Per ClinicalTrials.gov, last updated 2023-07-19.

Why
  1. The study's listed conditions name Tooth Wear, a narrower term within Tooth Diseases.
Confidence
High: the new condition is named in the study's own listed conditions. Of 351 hand-checked studies reclassified this way, 68% were exactly right and 84% in the right disease family; the registry's first term was right for 5% (measured 2026-10-21). How we classify →

Study summary

The goal of this clinical trial is to test the effects of prophylactic antibiotics in healthy individuals who are in need of surgical crown lengthening. The main question it aims to answer is if single dose antibiotics prior to surgical crown lengthening has any effects on the healing outcomes.

Participants will be asked to take either

  • 2 g of amoxicillin + clavulanate, or
  • placebo, one hour prior to surgery and without knowing what medicine they took.

Researchers will compare the wound healing and self-reported outcomes of the antibiotics group and placebo group.

In context

Tooth Wear Reclassified

62 studies on the registry are indexed under Tooth Wear; 12 are open to participants now.

This study's planned enrollment of 28 is below the median of 49 across 41 interventional studies indexed under Tooth Wear.

Lead sponsor

Biruni University is the lead sponsor of 180 studies on the registry; 45 are open to participants now.

Compared within Tooth Wear, this study's primary condition as ClinicalTrials.gg classifies it; the registry's first condition term is Tooth Diseases. The counts are of registry records indexed under each term, refreshed daily. How we classify →

Inclusion criteria

  • in need of surgical crown lengthening operation in one/two teeth

Exclusion criteria

Exclusion Criteria:

  • systemic diseases which may affect periodontal tissues and/or healing process such as diabetes mellitus
  • antibiotic or anti-inflammatory drug use in the last 3 months
  • pregnancy/lactation
  • chronic , or NSAD use
  • age \<18 years
  • positive bleeding on probing at the surgical site and/or active periodontal disease
  • \<2 mm keratinized mucosa at the surgical site following surgery (estimated surgical outcome before the operation)
  • Miller 2 or 3 tooth mobility
  • penicillin allergy
  • unwilling to participate
Terms in these criteria, in plain language(2)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Corticosteroids (steroids)

Anti-inflammatory medicines such as prednisone, prednisolone and dexamethasone — not the anabolic steroids used for muscle.

Studies differ in what they allow: check which steroid medicines, routes (tablets, injections, creams, inhalers, eye drops) and doses this study accepts.

Immunosuppression

A weakened immune system. It can come from an illness, such as HIV or some blood cancers, or from medicines that turn the immune system down, for example after an organ transplant or for an autoimmune disease; steroids at higher doses count.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Jul 19, 2023, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
