Objectives:Gingival recession is the term used to characterize the apical shift of the marginal gingiva from its normal position on the crown of the tooth. It is frequently observed in adult subjects. The occurrence and severity of the gingival recession present considerable differences between populations. To prevent gingival recession from occurring, it is essential to detect the underlying etiology. The aim of the present study was to determine the occurrence of gingival recession and to identify the most common factor associated with the cause of gingival recession.Methods:A total of 710 subjects aged between 15 years to 60 years were selected. Data were collected by an interview with the help of a proforma and then the dental examination was carried out. The presence of gingival recession was recorded using Miller's classification of gingival recession. The Silness and Loe Plaque Index, Loe and Silness gingival index, community periodontal index were recorded. The data thus obtained were subjected to statistical analysis using Chi-square test and Student's unpaired t-test.Results:Of 710 subjects examined, 291 (40.98%) subjects exhibited gingival recession. The frequency of gingival recession was found to increase with age. High frequency of gingival recession was seen in males (60.5%) compared to females (39.5%). Gingival recession was commonly seen in mandibular incisors (43.0%). Miller's class I gingival recession was more commonly seen. The most common cause for gingival recession was dental plaque accumulation (44.1%) followed by faulty toothbrushing (42.7%).Conclusion:Approximately half of the subjects examined exhibited gingival recession. The etiology of gingival recession is multifactorial, and its appearance is always the result of more than one factor acting together.

The study revealed that Dexmedetomidine being a new drug with its added advantages makes a better choice for sedation in dentistry. But with limited studies on Dexmedetomidine, the recommendation to use the drug exclusively is still under debate.

Microdontia is a term used to describe teeth which are smaller than normal. Peg-shaped teeth are type of microdontia, a developmental disturbances of teeth mainly due to congenital reasons. Most commonly affecting single teeth, that is maxillary lateral incisors. Incidence of peg shaped tooth in maxillary laterals are usually seen and reported. But in mandibular arch it is very rare. Present case, it affected all the incisors of mandibular arch and also the laterals of maxillary arch which is rarest of condition. This case report presents a non syndromic, peg shaped mandibular incisors in a 11 year old male patient.
