Introduction: Mini-implant assisted rapid palatal expansion (MARPE) is gradually becoming the treatment of choice to correct the transverse dimension, exceeding the limitations of conventional RME devices. One of the key factors for orthodontic diagnosis and treatment planning apart from a stable occlusion is a balanced and aesthetic facial profile that is influenced by maxillary expansion. Similarly, it also affects the anatomy and physiology of the nasal cavity since nasal airflow is a continuous stimulus for lowering of the palate and for lateral maxillary growth. Hence, there is a need to conduct further research on the effects of MARPE on the facial soft tissues as well as the airway, enabling the orthodontist to reach a more accurate diagnosis as well as aid in the treatment planning process. Aims and Objectives: This retrospective three-dimensional study was planned and designed with the objective of measuring facial soft tissue and airway changes in individuals treated with mini-implant assisted rapid palatal expansion (MARPE) using CBCT. Materials and Methods: This study was carried out on CBCT records of 10 patients in the age group of 18-30 years. These records were then imported into Romexis software and calibrated. The facial soft tissue and airway parameters were measured for each individual at selected landmarks and compared before and after expansion. Result: Statistically significant differences in the soft tissue parameters were observed, which included an increased H-angle, increased soft tissue subnasal to H-line and a decreased soft palate surface area after MARPE.

The aim of the study was to analyze the morphology and expedient the linear dimensions of Sella Turcica among cleft and non-cleft Indian individuals, and then to determine whether differences exist between different study groups. The lateral cephalogram of 300 patients (150 cleft and 150 non-cleft), aged 18 to 30 years who reported for various treatments of malocclusions were studied. The normal morphology of the sella turcica were seen in 85 of the 150 non-cleft individuals which was highest (56.66%) in the non-cleft group, however in the cleft group it was seen in only 16 of the 150 individuals (10.6%). Sella turcica bridge were seen in 10% of the non-cleft subjects, whereas in the cleft group it was seen in 38% of the individuals. A significant difference was seen in the linear measurements of the sella turcica of cleft and no-cleft individuals. The normal morphology of the sella turcica was seen in the majority of the non-cleft individuals. The cleft individuals showed an increased incidence of sella turcica bridging with reduced linear measurements of the sella as compared to the non-cleft individuals.

Aims: The aim of the study was to analyze the morphology and expedient the linear dimensions of Sella Turcica among Indian individuals having Skeletal Class I, Class II and Class III pattern, and then to determine if differences exist with different skeletal patterns. Methods and material The lateral cephalogram of 150 patients (75 males and 75 females), aged 18–30 years who reported for various treatments of malocclusions were studied. Statistical analysis used Analysis were done by ANOVA with Tukey's t-test, SPSS version 17.0 was used. P < 0.05 was considered as significant. Results: The normal morphology of the sella turcica were seen in 85 of the 150 individuals which was highest (56.66%) in the study group, an oblique anterior wall was present in 11.33% of the subjects, an irregular dorsum sella and sella turcica bridge were seen in 10% of the subjects, pyramidal shaped sella were seen in 6.66% and 5.33% of the subjects had double-contoured sella turcica. No significant difference between males or females in terms of diameter, depth or length was evident. A significant difference was observed among different skeletal patterns and the diameter of sella. Conclusions: The normal morphology of the sella turcica was seen in approximately 57% of the individuals. The larger diameter values were seen in the skeletal Class III subjects, while the smaller diameter values were observed in the Class II subjects.

Dental caries and periodontal disease are two of the most common oral diseases caused by bacterial infections. Traditional medicine in India has a long history of using plant extracts for dental care. Spilanthes acmella (S. acmella), also known as the “Toothache Plant,” is a medicinal plant that has been traditionally used for its medicinal properties but has not been extensively studied for its applicability and use in dentistry. This study aims to investigate the antimicrobial action of S. acmella ethanol extract on Streptococcus mutans (S. mutans), and Lactobacillus fermentum (L. fermentum), which causes dental caries, and Porphyromonas gingivalis (P. gingivalis), Capnocytophaga gingivalis (C. gingivalis), which causes periodontal infection. The ethanol extract of S. acmella in various dilutions of 10mg/ml, 20mg/ml, 40mg/ml, 80mg/ml, and 100mg/ml was tested for its antibacterial activity against the bacteria as mentioned above using the agar well diffusion method. Erythromycin 0.125mg/ml was used as a positive control, whereas distilled water was used as a negative control. The Minimum inhibitory concentration (MIC) and Minimum bactericidal concentration (MBC) were determined by the broth dilution method. The results of this study have shown that the ethanol extract of S. acmella demonstrated concentration-dependent inhibition of bacterial growth (13-16mm diameter), with the highest concentration of 100mg/ml showing the strongest effect. The findings of this study support the use of the S. acmella plant extract in the treatment of dental caries and periodontal infection and suggest that it may be a viable alternative to traditional antimicrobial agents.

Background Development of malocclusion can be promptly recognized through an understanding of the optimal position of the bone structures in the orofacial system and their relationship to the cranial base and jaw base. The aim of this study was to assess the relationship between the cranial base, mandible, and hyoid bone in different anteroposterior skeletal malocclusions. Materials and Methods This retrospective study evaluated 120 lateral cephalometric radiographs of individuals aged between 15 and 30 years. The subjects were classified using Burstone's analysis into three groups based on the N perpendicular to point A and N perpendicular to point B. The collected lateral cephalograms of the selected individuals were analyzed using Nemoceph v.12 software (Nemotec, Spain). The nasion-sella-articulare (NSAr), hyoidale angle (C3HyD), sella-articulare-hyoid angle (SArHy), and nasion-sella-hyoid (NSHy) angles were measured and compared among all the three groups. Results In the present study, considering the various angles among the three study groups, a statistically significant difference was observed for the SArHy angle (p < 0.05). However, the saddle angle (NSAr) and hyoidale angle (C3HyD) showed no statistically significant difference between the three study groups. Post hoc Bonferroni test was applied to compare the differences between two groups. A statistically significant difference (p < 0.05) was observed between class I and class II and between class II and class III groups. Conclusion Though the findings of the present study concluded that there is no variation in saddle angle among the three groups, the significant association of SArHy angle among class I, class II, and class III skeletal relationships, suggests an adaptation of the hyoid bone position in various skeletal patterns. We also suggest that the posterior positioning of the hyoid bone is related to skeletal class II malocclusion, whereas a forward positioning of the hyoid bone is related to skeletal class III malocclusion.
