Abstract
Introduction: Dentures are common tooth replacement
option and they may pose an increased periodontal risk
to abutment teeth resulting in premature tooth loss.
Aims and Objectives: To determine if a difference
exists between periodontal parameters of abutment
teeth, and non-abutment teeth on the same of the
edentulous area in prospective denture wearers.
Materials and methods: Consecutive partially
edentulous patients demanding for removable partial
denture were selected. Interviewer-administered
questionnaires were used and examination done with
dental instruments - mouth mirrors, dental explorers and
periodontal probes. Selected non-abutment teeth were
adjacent to the abutment teeth on the same arch.
Plaque assessment and periodontal pocket depths were
done on the four surfaces (buccal, lingual, mesial and
distal) of all abutment and non-abutment teeth excluding
third molars. Probing depth estimated to the nearest
minimum was recorded for the selected teeth, and data
collected was analyzed with IBM SPSS 20. Student t
tests and ANOVA were utilized.
Results: Sixty-one participants with mean age of 60.9
± 14.27 years, and age range from 21to71 years were
seen. Thirty-six (59%) were male. Majority (96.8%)
brushed with toothbrush only, 51.5% brushed once a
day and 57.4% had Kennedy class III edentulous
arches. Mean probing depth of abutment (2.40 ± 0.16
mm) and non-abutment teeth (2.24 ± 0.15 mm) varied
significantly (p <0.001). Majority of those who brushed
once daily and those who had Kennedy Class III
edentulous spaces had poor Oral Hygiene (p <0.0001,
p=0.03 respectively). Differences in the probing depth
of abutment (F=0.46), non-abutment teeth (F = 1.11)
and oral hygiene (F = 1.13, p=0.71, p=0.35, p = 0.34
respectively).

Conclusion: Abutment teeth of edentulous spaces had
poorer periodontal status than non-abutment teeth,
suggesting increased risk for periodontal disease for
prospective abutment teeth. Greater attention should
therefore be given to these abutment teeth during oral
hygiene measures in denture wearers. Location of
edentulous space on dental arch have significant
relationship with oral hygiene status.
