Prevalence and gender differences of buccally displaced canines of 12 years school children and 18-23 years adults in Shah-Alam, Malaysia

Background: The buccally displaced canines (BDC) are more commonly encountered conditions in orthodontic clinics. It is a positional variation result of several factors such as retained deciduous canines, crowding, and lateral incisors anomalous. Aims: To determine the prevalence and gender differences of one-two-three-four buccally displaced canines in the area of Shah-Alam, Malaysia. Methods: A cross-sectional study of 399 subjects; was consist of two age groups; 208 subjects of school children aged 12 years and 191 subjects of adults aged 18-23 years were examined clinically to determine the prevalence of BDC. Statistical analysis: The data were statistically analyzed using SPSS version 16; a Chi-square test was performed to assess the gender differences. Results: No gender differences were found in the school-children group while in the adults group a significant gender difference was found regarding one and four canine displacements (P < 0.05). The prevalence of one-two-three canine displacement was higher significantly between the two groups (P < 0.05). However, the frequency of one canine displacement was higher significantly in adult females and girls (P < 0.05). The frequency of three canines displacement was approximately equal in both genders. Conclusion: The frequency of one canine displacement was higher significantly in females. However, the frequency of four canines displacement was higher significantly in males. These features may help in providing additional clinical signs in diagnosis and interception of such clinical situation.

Diabetes mellitus and periodontal diseases: A two way relationship

Diabetes mellitus and periodontits are both highly prevalent chronic inflammatory diseases. Both diseases share the same risk factors and are a significant global health care burden adversely affecting the quality of life. Evidence from various studies have demonstrated that diabetes is a major risk factor for periodontal disease and is associated with increased incidence, prevalence and severity of periodontal disease. Hyperglycemia associated with diabetes mellitus results in an increased host immunoinflammatory response which adversely affects the periodontal health. Conversely, periodontits is associated with poor metabolic control in patients with diabetes and increased development of diabetic complications suggesting a bidirectional relationship between the two diseases. Periodontal infection via bacteremia exerts a wide systemic effect by contributing to chronic systemic inflammatory burden worsening diabetic state by increasing insulin resistance. Moreover, studies have demonstrated an improvement in glycemic control following periodontal therapy in prediabetic and diabetic patients with periodontitis.

Emancipators in oral sub mucous fibrosis: An update

Oral submucous fibrosis is a chronic insidious oral mucosal condition causing trismus and reduced mouth opening and it is affecting predominantly Indian and other Asians. The treatment of trismus requires combination of pharmacological agents, surgical therapy and physiotherapy, the latter is essential for preventing relapse due to postoperative inactivity and scarring as well as for improvement of mouth opening. Computerized literature search was performed from 1993 till 2021 to select eligible articles from the following databases: PUBMED [MEDLINE], SCOPUS, SCIENCE DIRECT, and COCHRANE DATABASE using specific keywords. The search was limited to articles published as full text in English, which were screened by two reviewers for eligibility.This article describes in depth about various appliances, devices used in oral submucous fibrosis. The devices can be used along with pharmacological and surgical treatment modalities or can be used alone. Mouth exercise is also well-established method to improve mouth opening and also to prevent postsurgical relapse. This article is one of the rare article that describes all the appliances together either directly used or indirectly used for the case of microstomia due to oral sub mucous fibrosis.

Squamous Cell Carcinoma of lower lip: A Review and Case Report

Background: The prevalence of Squamous cell carcinoma (SCC) accounts for about 25% of all the oral cancers. The surgical treatment plan comprises of excision of tumour, dissection of lymph node and tissue reconstruction for restoring functions. Case presentation: A 58-year-old patient reported with a painful mass on lower lip. It was an ulceroproliferative lesion on the right side of the lip and measures 15x9 cm in size. The excisional biopsy when taken showed moderately differentiated squamous cell carcinoma. Conclusion: Excision of tumour, lymph node dissection and reconstruction are the ideal treatment modality that is followed for SCC of lip. Selection of reconstruction method is dependent on several factors and V-Y advancement flap which is commonly employed presents a leading edge in the treatment of carcinomas of lower lip.

Effect of omega 3 fatty acids plus low dose aspirin as a host modulating agent in the treatment of periodontitis patients- A Systematic Review

Background and Objectives: Host Modulatory Therapy is a treatment modality for periodontal diseases. It aims at reducing the periodontal destruction and enhances the regenerative capacity of periodontal tissues. Various host modulating agents are used as an adjunct to scaling and root planing. Omega 3 Fatty acids and non-steroidal anti-inflammatory drugs like Aspirin modify the activity of inflammatory mediators and exert anti-inflammatory effect. The objective of the systematic review was to evaluate the effect of Omega 3 Fatty acids plus low dose Aspirin as adjunct to mechanical debridement in reduction of pocket depth in patients with periodontitis. Methods: In this systematic review, Randomized controlled trials in subjects with periodontitis in age group of 25-70 years were considered. Follow up period ranged from 6 weeks to 6 months. A systematic review of literature was performed using Pubmed, PMC, Google scholar, EBSCO host databases. Studies concerning the use of Omega 3 Fatty acids plus low dose Aspirin as host modulating agent in periodontitis treatment were selected. A total 2650 of studies were selected through search strategy and 5 articles which attained the inclusion criteria have been included in present systematic review. Results: Oral supplementation of omega 3 fatty acids in combination of low dose Aspirin as adjunct to mechanical debridement reduces the pocket depth during the 6 weeks to 6 months follow up period. Limitations: There are limited studies which are available. Also there is lack of data evaluating the long term follow up of the intervention. Conclusion: Use of omega 3 fatty acids and low dose aspirin in periodontitis patients improves periodontal status but further long-term studies need to be conducted.

A Comparative Analysis of Cytotoxicity of Three Different Root Canal Sealers

Aim: This study aims to evaluate Well-Root ST in comparison with CeraSeal and AH Plus regarding cytotoxicity using (MTT) assay on human epithelial type 2 (HEp-2) cells. Materials and Methods: Teflon mold was used to fabricate disc samples of each root canal sealer. Samples were divided into 3 groups: group (A) (Well-Root ST), group (B) (Ceraseal) and group (C) (AH Plus) in two evaluation periods (24h and 72h). All samples of root canal sealers were mixed according to the manufacturer’s instructions and the discs were allowed to set in a at 37°C for 24 hours before extraction. Extract collected at each time point was diluted to various concentrations of 12.5%, 25%, 50% and 100% with DMEM to create a total of four different concentrations of each extract. DMEM incubated for 24 hours served as the control. (HEp-2) cell line was seeded in 96 well micro-titer plates and cultures were then subjected to 100 μL of the (12.5%, 25%, 50% and 100%) extracts medium while cell cultures with supplemented DMEM were used as controls. The plates were left in the incubator for 24 or 72 h before the cytotoxicity evaluation was carried out by (MTT) assay. Viability percentage was calculated and cytotoxicity was evaluated by rating according to cell viability relative to control group, non-cytotoxic (more than 90%), slightly cytotoxic (from 60 to 90%), moderately cytotoxic (from 30 to 59%) and severely cytotoxic (less than 30%) cell viability. Statistics: Data were collected, tabulated and statistically analyzed using one way ANOVA test and Bonferroni's post-hoc test. Results: According to evaluation time, Well-Root ST showed the highest viability values in all concentration percentages at both intervals (24 and 72 hours) while AH plus showed the least viability values. According to concentration percentage, The viability increased with decreasing the concentration in all tested groups. Conclusion: The evaluated root canal sealers showed varying degrees of cytotoxicity. However, Well-Root ST was associated with significantly highest cell viability percentages. 1- AH plus significantly showed less cell viability in comparison to calcium silicate-based root canal sealers.

The role of CT and MRI scans in maxillary sinus augmentation surgery

Diagnostic imaging has a primary role in presurgical planning. Computerized tomography has become a standard for assessing the feasibility of implant surgery. Three- dimensional diagnostic assessments have a decisive value in presurgical treatment planning, especially in situations in which the alveolar process has pronounced resorption, and therefore insufficient bone volume for placing endosseous implants. These situations, which once limited the placement of implants in the posterior maxilla, can now be overcome via maxillary sinus augmentation procedures. In these cases, diagnostic imaging, in particular using CT scans, plays a vital role in providing reliable and necessary information. MR imaging reveals to be ideal imaging in diagnosing maxillary sinus augmentation.
