Introduction:
Gingival biotype is said to have an influence on the results of restorative procedures, regenerative therapy and implant placement. It has also been documented that a definite association exists between gingival recession followed by any surgically operative procedure. Multiple studies in various countries have been done to find prevalence of gingival biotype in the pertinent population but no such study exists involving Pakistani population. This study was planned with the objective to evaluate the frequency of occurrence of thick and thin gingival biotype and width of attached gingiva (WAG) in a subset of the Pakistani population.
Methodology:
Anterior teeth in the upper and lower arches were utilized for all the measurements of gingival type and width. The Gingival biotype was assessed by TRAN method at mid-buccal area of the tooth. To estimate the width of attached gingiva, pocket depth was subtracted from the total width of attached gingiva which is found from gingival margins to mucogingival junction.
Results:
Out of the 400 participants that took part in the study, 56.3% (225) were male and
43.8% (175) were female. 57% of the participants possessed thick gingival biotype while whereas 43% had a thin gingival biotype tissue. The biotype in the maxillary arch for the tested population was predominantly thick among age groups below 40 with the 20 – 30 -year -old category showing the greatest difference between the thick and thin types. Furthermore, the average biotype in the mandibular arch showed similar findings except that at ages 31-40, thinner biotype more frequently prevailed. The highest average width in the maxillary arch was 5mm. Additionally, in the mandibular arch the width of the keratinized gingiva portrayed significant findings as well. With an average of 4 mm as the most frequent found. When gender was compared with the type of gingival tissue and the width of the keratinized gingiva in the maxillary and the mandibular arches, it was found that an insignificant relationship existed between the variables.
Conclusion:
It has been demonstrated that the thick biotype was more prevalent in overall population with maxillary arch having significant findings. However, the thickness of gingivae reduces with increasing age.
