Determination of rugae pattern in non-treated normal angle class I, II and class III mal-occlusion
Keywords:
rugae pattern, postnatal palatal growth, determinationAbstract
Background: Palatal rugae are specialized patterns in keratinized mucosa of the anterior hard palate behind incisive papilla tis are unchangeable in their site and form, all over an individual’s lifespan. Occlusion means “closure” which refers to the interaction among upper and lower teeth. Mal-occlusion is improper alignment of teeth when the upper and lower jaws are closed. Objectives: The objectives of this study is to assessment of palatal rugae arrangement in our population and the determination of rugae pattern in non-treated Class-II and Class-III mal-occlusions when related to Class-I normal mal-occlusions. Methodology: It’s observational and cross-sectional study conducted at Orthodontics department, Lumhs jamshoro and Hyderabad. The sample size of study was 135, the Pre-treatment record of those patients who are receiving orthodontic treatment were enrolled as study participants their maxillary dental cast was assessed for assessment of rugae, Maxillary dental casts were assessed and maxillary impression were recorded using Alginate (irreversible hydrocolloid), impressions then were poured using dental stone. The Rugae pattern on the study casts were traced with a black graphite pencil to clarify the pattern.
