Background:
For any esthetic treatment planning, the shape and form of gingiva should be a prime factor of concern. The correct identification of gingival phenotype (GP) ensures a firm foundation for future health and prognosis of the treatment indicated. Hence, the aim of the present study was to evaluate the correlation between the GP in the anterior esthetic zone with different types of maloclussion and severity of crowding.
Materials and Methods:
A total of 110 periodontally healthy controls were equally divided into two groups depending on the type of malocclusion. They were further divided according to the levels of dental crowding as mild, moderate, and severe. GP was measured on the anterior esthetic teeth using transgingival probing, and width of the attached gingiva (WAG) was measured using histochemical staining method.
Results:
In severe crowding group, the GP in 12 and 22 region was found to be thick (
P
= 0.035) while, in 32 and 42 region was thin (
P
= 0.042). The WAG shows a significant difference between WAG with 23 in severe crowding group with
P
= 0.042, whereas there was no significant relationship found between the GP with Angle's classification.
Conclusion:
Within the limitations of the study, it can be concluded that the teeth in the maxillary and mandibular anterior esthetic region showed the thin phenotype. When the severity of crowding increases, the GP and WAG vary depending on the position of the tooth. There is no association between the Angle's classification and the mean GP of the maxillary and mandibular anterior region teeth.
Background
The present study aims to evaluate and compare the efficacy of locally delivered 1% melatonin gel as an adjunct to non‐surgical periodontal therapy (NSPT) in treatment of intrabony defect in Stage III periodontitis, clinically, and radiographically using cone‐beam computed tomography (CBCT).
Methods
This split‐mouth clinical trial randomly allotted 44 bilateral intrabony defect (in 22 patients) into two groups where Group I was treated with NSPT with locally delivered placebo gel while Group II was treated with NSPT with 1% melatonin gel. The intrabony defect fill measured from cemento‐enamel junction (CEJ)‐base of the defect (BD), and the difference in the measurement values of CEJ‒BD from baseline to 6 months denoting the bone fill and bone volume evaluated at 6 months using CBCT were the primary outcome measures. Secondary outcome measures were change in probing depth (PD), clinical attachment level (CAL), plaque index, and modified sulcus bleeding index recorded at baseline, 3 months, and 6 months.
Results
Both the study groups showed improvements in assessed parameters, however, a significant gain in intrabony defect fill was observed in Group II (1.46 ± 0.58) as compared with Group I (0.50 ± 0.38) and change in bone volume for Group I was 21.4645 ± 8.8980 mm3 and for Group II was 51.8418 ± 30.2329 mm3 with P < 0.0001.The mean reduction in PD and gain in CAL was 3.90 ± 0.78 and 2.94 ± 0.80 in Group II and in Group I it was 3.23 ± 0.90 and 1.96 ± 0.80 (P < 0.0001).
Conclusion
The use of 1% melatonin gel as an adjunct to NSPT is more beneficial in achieving better clinical and radiographic outcome at 6 months which indicates that adjunct use of melatonin gel to NSPT as a local drug delivery is preferred when compared with NSPT and placebo gel alone.
