Abstract
Background: Wound healing is a physiological process that undergoes series of phases which is well connected.
The sequence of the wound healing process is critical and influenced by varied factors that act locally and
systemically. The systemic factors that influence the health can affect healing through local factors. Oral cavity is
different in many aspects including its scarless healing which happens at a faster rate. SARS CoV2 may influence
viability of salivary glands, taste, smell sensations, integrity of oral mucosa, the balance on the microbiota. Recent
literature strives need for clarification on post covid effect in oral cavity.
Aim: An Observational Study to Identify influence of SARS Cov2 on Physiological process of Wound Healing after
Dental Extraction.
Materials And Methods
Study population: Patients recovering from covid-19 undergoing Tooth extraction. Healthy patients undergoing
tooth extraction unaffected by covid-19. 35 cases with history. 35 cases without history of covid were involved.
After extraction patients were assessed clinically using Laundry et al criteria. VAS scale used to assess pain
intensity.
Results:Covid positive patients on day 3 when assessed with Landry et al healing index for post extraction wound
healing, scored 2(33) and 3(2). Bleeding on palpation was noticed on day 3. VAS scored around 1 and 2 for both the
patients with, without history. Covid negative patients on day 3 when assessed for post extraction wound healing
scored 3(35), bleeding on palpation was not evident on day 3. Covid positive patients on day 7 when assessed for
post extraction wound healing, scored 3(16), 4(18), 1(1). Covid negative patients on day 7 when assessed for post
extraction wound healing scored good and excellent.
Conclusions: We hypothesize there could be a prolonged early phase of wound healing in dental extraction wounds
in patients with history of covid, which could be another feature of long covid syndrome in oral cavity.
