    (Wolters Kluwer Medknow Publications, 2023) Sharma, Vipul Kumar; Singh, Deepak; Srivastava, Roopal; Chaturvedi, T.P.; Khairnar, Mahesh; Singh, Akhilesh Kumar
    Objective: The aim of the present study is to evaluate the relationship of gingival biotype in different malocclusions. Methods: A total of 157 periodontally healthy subjects (88 males and 69 females) were enrolled in this cross?sectional study. The study participants were divided into three groups of skeletal class I, class II, and class III. The probe transparency method was used to determine the quality and gingival tissue into thick and thin biotype. Results: There was significant difference in gingival biotype among different skeletal malocclusion with high prevalence of thin gingival biotype in class I subjects and more prevalence of thick biotype in class II and class III individuals (P?value: 0.022). Pairwise comparison of gingival biotype in class I versus class II showed significant difference (P?value: 0.032); however in class I versus class III and class II versus class III, the test result was nonsignificant. The overall frequency of thin gingival biotype was significantly less in female subjects with respect to males (P?value: 0.025). Conclusion: A significant relationship is present between skeletal malocclusion and quality of gingival biotype. The prevalence of thick gingival biotype is found more in females as compared to male individuals. The thin gingival biotype is more commonly seen in skeletal class I than class II and class III. � 2023 National Journal of Maxillofacial Surgery.

    White spot lesions in clear aligner therapy as compared with multi-bracket system: A Systematic Review
    (IP Innovative Publication Pvt. Ltd., 2023) Singh, Deepak; Sharma, Vipul K.; Srivastava, Roopal; Priyadarshani, Pooja; Chaturvedi, T.P.
    Aim and O bjective: To evaluate incidence of white spot lesions in clear aligner treatment compared with fixed appliance therapy. Materials and Methods: Electronic databases (PubMed, Cochrane Collaboration Oral Health group database of clinical trials, Web of Science, Science Direct, Scopus) and manual search of gray literature were conducted up to September 2021. Both randomized and non-randomized controlled studies were considered for review purposes. Study selection, data extraction, quality assessment (RoB 2.0 and ROBINS-I) was performed according to the Cochrane Handbook for Systematic Reviews of Intervention. Due to the presence of high heterogeneity only qualitative analysis has been done. Results: Out of 479 retrieved literature, 3 studies fulfilled the eligibility criteria and were included in the analysis. Studies were evaluated at low to high risk of bias. On qualitative analysis, a total of 160 new white spot lesions were developed in the clear aligner group and 362 new lesions were found in the fixed orthodontic group (P <0.001). In addition, the surface area of white spot lesion in the clear aligner group was more than the fixed appliance group but the deepest lesion was still found in the fixed appliance group. Conclusion: Incidence and severity of white spot lesion was found more in the fixed appliance group as compared to the clear aligner group. However, more low risk of bias studies with proper methodological quality is required to reinforce the conclusive evidence. � 2023 Author(s).
