ABSTRACT
Objective: The objective of this study is to assess the prevalence of gingival recession (GR) and associated etiological factors among school children. Methodology: The study sample consisted of 2095 children from the Nellore region divided into three groups of age ranges from primary dentition (<7 years), mixed dentition (7–12 years), and permanent dentition (>12 years) respectively, attending the department of pediatric and preventive dentistry and the school dental health programs organized by the department. The clinical examination involved measuring GR using William's periodontal probe and evaluating associated etiological factors. Data were statistically analyzed using the Chi-square test. Results: The GR among the study population was 7.9% (n = 165). Among them, males were 46% and females were 54% (P > 0.05). The GR was more in children in the 7–12 years age group (75%), followed by <7 years (21%) and >12 years (4%) age groups. The associated factors include malocclusion (69%), deleterious habits (5%), and anomalies (26%). Anomalies showed an association with GR (P < 0.05) compared to malocclusion and deleteriousness habits (P > 0.05). Conclusion: The prevalence of GR is 7.9%, and GR is more prevalent in males and the 7–12 years age group. GR is associated with transient malocclusion, deleterious habits, and anomalies.
ABSTRACT
The tooth development involves a complex series of genetic interactions involving growth factors, transcription factors, signal receptors and diffusible morphogens that interact within independent signalling pathways. This report describes a case of occlusal dysmorphology and a root variance of maxillary right first molar which almost mimicked that of a rotated mandibular 1st molar. The cuspal variation of mesiodistal was same as that of 36. This kind of variation may be due to Genetic or Environmental factors or interplay of both. So there is a need for research to be done in this aspect in larger group.
