Aim:Evaluation and comparison of serum C-reactive protein (CRP) levels in subjects with chronic and aggressive periodontitis.Materials and Methods:Based on the periodontal status, 45 subjects were selected and divided into three groups. Group I – subjects with clinically healthy periodontium, Group II – generalized aggressive periodontitis (GAP), and Group III – chronic periodontitis (CP). Blood samples were collected from subjects for measurement of CRP. Periodontal parameters include plaque index (PI), gingival index, bleeding index (BI), probing pocket depth (PPD), and clinical attachment loss (CAL) were assessed. CRP levels were assessed by means of a commercially available high sensitivity-CRP enzyme immunoassay kit.Results:CRP levels were increased in Group III (6.0671 ± 3.15639 mg/L) and Group II subjects (4.5453 ± 2.88116 mg/L) compared to the Group I (1.0180 ± 0.94069 mg/L). CRP levels showed a positive correlation with all clinical parameters in Group I subjects. BI (r = 0.073), PI (r = 0.120) showed a positive correlation with CRP level in Group II and a positive correlation was also seen for PI (r = 0.492), PPD (r = 0.340), CAL (r = 0.160), and CRP level in Group III subjects.Conclusion:The mean CRP levels were found to be greater in CP compared to GAP subjects, but there was no statistically significant difference.

Objective: To study the correlation between mandibular growth variables using linear measurements of ramus, body of the mandible and total mandibular length with skeletal maturity indicators such as hand wrist radiographs and cervical vertebral maturation. Materials and Methods: A total of 315 patient-records (lateral cephalograms and hand-wrist radiographs) in the age group of 10-13 years were involved. The cephalometric measurements, representative of the mandibular growth, Condylion-Gonion (Co-Go), Condylion-Gnathion (Co-Gn), Gonion-Gnathion (Go-Gn), and posterior-most point of the mandibular condyle-pogonion (Fg-Pg) were traced (McNamara method). The correlation of mandibular growth variables with hand wrist parameters and cervical vertebrae maturation were assessed separately in male and female. Pearson’s correlation was used for analysis (Statistical Package for Social Sciences version 17). Results: Only 80 subjects were included in final analysis. A highly significant correlation was found among hand wrist parameters, and mandibular growth variables ( P < 0.001) in both genders. Among males, there was a highly significant correlation between cervical vertebral maturation and mandibular growth variables ( P < 0.001), whereas Co-Go has a significant correlation with C2Conc, C3Conc, and C4Conc ( P < 0.05). In females, Co-Gn, Co-Go, Go-Gn, and Fg-Pg were significantly correlated with C3Conc and C4Conc ( P < 0.001). Conclusion: Both the cervical vertebral maturation and mandibular growth variables can be accessed on the lateral ephalogram itself for the evaluation of the skeletal maturity, as effective as a hand wrist radiograph in males and females.
