Abstract
Objective: To determine the prevalence and association of Ponticulus Posticus with dental and skeletal
malocclusions in our local population.
Study Design: Cross sectional, observational study
Place and Duration of Study: Orthodontics department of a tertiary care hospital based in Islamabad using
st st
records between the duration of 1 March, 2014 – 31 February 2018.
Materials and Methods: The study was conducted using lateral cephalograms of the patients visiting the
Orthodontic department which were analysed against age, gender, skeletal and dental malocclusions of the
patients obtained from the patient records. For the incidence of Ponticulus Posticus a total of 1194 radiographs
were obtained using convenience sampling and analysed using SPSS version 17 and Pearson's Chi-Square test
was applied.
Results: A combined frequency of PP was found to be 18.1% (181/817). A higher frequency in males 22.6%
(77/264) as compared to females 15.8% (104/553) exhibited a significant difference (p < 0.05).
Partial type of Ponticulus Posticus was more frequent (61.3%) as compared to Full (38.7%). Partial variant
expressed a higher frequency in skeletal (49.5%) and dental (48%) class II malocclusion. Whereas, the full
variant of Ponticulus Posticus exhibited a higher frequency in Dental Class II (48.6%) and skeletal Class I (55.7%)
respectively.
Conclusion: Our data suggests that frequency of Ponticulus Posticus in our local population shows male
preponderance in dental class II malocclusion, however, no significance was established in relation to its
association with skeletal or dental malocclusions.
