Abstract:

Early treatment can have numerous benefits for patients presenting with anterior crossbite in mixed dentition. As this malocclusion seldom corrects by itself, early orthodontic intervention can improve function, esthetics and self-esteem. Various treatment options such as removable and fixed appliances have been suggested by different authors in the past literature. In this case series report, 4 patients aged from 8 to 10 y/o diagnosed with unilateral or bilateral anterior crossbite were treated with lower inclined bite plate combined with or without orthodontic bracket bonding based on the amount of teeth involved. With careful observation, each case was corrected within a short period and followed up for at least 12 months. The procedure has shown to be effective and simple if the symptoms are diagnosed and intervention occurs in the early age of mixed dentition.

Abstract:

This study analyzed the presence of antral septa in the maxillary sinus. A septum is a barrier of cortical bone and may split the sinus into two or even more than two cavities. Between 13% and 35% of the sinuses have these septa. Different methods to detect the presence of maxillary septum before dental surgery can be used. To know the prevalence of a septum before an external sinus floor elevation could be necessary to avoid surgical complications. CT-scan images collected from 120 maxillary sinuses of 60 patients from two dental clinics, which were processed by Fan beam CT scan, GEMS ZeusRP/Simplant and GE/Dental Scan by Radiology department of Cathay General Hospital were included in this study. The locations and distribution of spikes and septum’s were identified from the images and recorded. According to the most frequent areas, 3 categories were classified: Second premolar (P2), first molar (M1) and second molar (M2) according to the related tooth position. The difference between sides, sites and incidence were compared. Out of 60 patients, 17 showed no septum identified in both sinuses and 8 showed on one sinus. The rest can be detected on both sides. The incidence of a spike in the maxillary sinus in patients is 43/60. From 120 sinuses, 68 sinuses with 85 spikes or septum’s were identified. The incidence of a spike in the maxillary sinus on sinus is 85/120. Three areas were categorized as second premolar (P2), first molar (M1) and second molar (M2) according to the correlated tooth position. Spikes were 33 in second premolar (P2) position, 22 in first molar (M1) and 30 in second molar (M2) position; 48 on the right side and 37 on the left. The incidence of a spike in the maxillary sinus in patients is high (71.67%) and on sinus (70.83%). The incidence of sinus with spike is higher on right (39 vs. 29). The incidence of spikes detected slightly higher on right sinuses (48 vs. 37). Spikes were detected higher in second premolar (P2) and second molar (M2) than first molar (M1).

Abstract:

Azo is dye synthesis used in batik industries. It can be toxic to the tissue when exposed via inhalation, swallowing or contact directly. Expression of cytokeratin will change on hyperplastic and cancer of the oral mucosa. Expression of cytokeratin 8, 18, 19 was strong in the epithelial cells that undergo excessive hyperproliferation and oral mucosal changes into leukoplakia and squamous stratification carcinoma. The purpose of this study was to analyze the expression of cytokeratin 19 in the epithelial cells of the buccal mucosa exposed azo. The study involved 30 male subjects divided into 2 groups, 15 subjects were exposed azo and 15 were control. Criteria for exposed azo subject were worked at batik coloring parts for at least 5 years, while control was being not exposed to azo dyes. The method of collecting buccal mucosal epithelial cells was exfoliative cytology using cytobrush. Expression of cytokeratin 19 were analyzed using monoclonal antibody cytokeratin 19 (Novus Biologicals, USA) and immunohistochemical staining (ABC Staining Kit, ImmunoCruz, Santa Cruz Biotechnology, USA). Data were analyzed using independent t-test. The results showed a negative expression on the control while positive expression in the exposed group. T-test analysis showed significant differences in the positive expression of the exposed group compared to controls. In conclusion, azo dye could increase expression of cytokeratin 19 on buccal mucosa epithelial cells.

Abstract:

Flap advancement is a critical part of surgical procedures, such as guided bone regeneration, guided tissue regeneration and root coverage. By coronally positioning the flap, healing by primary intention can be achieved. Primary closure will protect the wound, prevent bacterial contamination and ensure a predictable outcome. Failure to attain tension-free closure will result in wound dehiscence, early membrane exposure and post-operative complications. This oral presentation focuses on periosteal tension releasing techniques addressed in recent articles about periosteal incising methods, including anatomical landmarks, surgical site assessments and summarizing the pros and cons of these techniques based on histology. Finally, several cases about flap advancement will be presented.

Abstract:

A periapical lesion is formed within an area of existing apical periodontitis, the foci of infection being the degenerating pulpal tissues within the root canal system. This pulpal degeneration is caused by the microbes that enter the pulp chamber from oral cavity. These periapical lesion regresses as soon as the microbial etiology present within the root canal is removed by nonsurgical root canal therapy. Mere surgical removal of the periapical lesion, without proper root canal disinfection and three dimensional obturation is not sufficient for its complete healing. Non-surgical endodontic treatment using triple antibiotic paste (TAP) as intra-canal medicament to disinfect the root canal system followed by mineral trioxide aggregate (MTA) for three dimensional obturation offers a high success rate in the healing of large periapical lesions. These clinical cases highlight the healing of large periapical lesions with conservative non-surgical endodontic treatment, followed-up over a period of 1-2 years.

Abstract:

Diagnosis and treatment planning in the cases of trauma is one of the emergencies that practitioners should be able to manage according to latest methods and guidelines. Trauma injuries almost happen in childhood and on the anterior teeth. An appropriate management has a great impact in patient’s quality of life. Trauma injuries can be harmful for teeth and their supportive structures. Examples of these injuries are crown fractures with or without pulp exposure with incidence of 0.9% to 13% and horizontal root fracture with incidence of 3% that effectively manage these conditions and probably has a great impact on long term prognosis of teeth. Variety of treatment options can be considered according to injury type, tooth developmental stage and patient’s age. In this presentation, diagnosis and treatment planning of crown fractures and horizontal root fracture will be discussed. Finally the treatment sequences, results and two years follow up of a case with complicated crown and horizontal root fracture and orthodontic force eruption will be reported.

Shraddha Rathi is currently working as Assistant Professor at Department of Prosthodontics, Aligarh Muslim University. Her thrust areas are Geriatric Dentistry and Nanotechnology. Her sole aim of presenting this paper is to relate nanotechnology with nutrition amongst compromised population. She wishes to spread this message that with the correction of micro deficiencies one can improve the health of elderly magnificently.

Abstract:

During the aging process, physical frailty may develop. A more sedentary lifestyle consequently results in lower energy expenditure and poor dietary intakes are important contributors to the development of a suboptimal nutritional state or multiple micronutrient deficiencies. Nutritional needs of the older individuals are determined by health status; caloric requirements; the ability to digest food and personal food preferences. Such condition can be improved by food fortification, nutritional snacks, nutritional supplements, flexible portion sizes, flexible timing of meals and snacks. The tantalizing potential of nanotechnology is to fabricate and combine nanoscale approaches and building blocks to make useful tools and, ultimately, interventions for medical science, including nutritional science, at the scale of ∼1–100 nm. Specific applications of nanotechnology to date in food and nutrition include: Detection of food pathogens and spoilage microorganisms; enhancing nutrition quality of foods; and novel vehicles for nutrient delivery. By reducing the size of a particle at the nanoscale (10⁻⁹), the total surface area in a product is greatly increased. The greater the surface area, greater will be its biochemical reactivity. This results in much greater efficacy. This means that a nutrient in an aqueous formulation becomes readily available for utilization at the cellular and subcellular level with previously unobtainable levels of efficacy. Because of the increased bio-availability along with enhanced efficacy and reduced dosage, majority of essential nutrients and other beneficial chemicals can be combined and given as one or two dosages only. This will also improve the compliance by elderly individuals and thus in-turn improve their overall health & well-being.

Abstract:

The aim of the study was to evaluate the soft and hard tissue healing with and without bone grafts after removal of impacted mandibular third molars. Objectives included evaluation of bone formation on radiographs, as well as measuring the probing depth and dentinal hypersensitivity at the surgical site; pre and post removal impacted mandibular third molar. 60 sites in 30 patients with horizontally impacted mandibular third molars were selected for the study.  In a split-mouth design study, in all 60 sites, surgical removal of mandibular impacted third molars was done. Randomly selected 30 sites received alloplastic bone graft material. Remaining 30 sites acted as controls. Parameters measured included pocket depth distal to the mandibular second molar. Radiographs (OPG) were obtained and hypersensitivity was measured at 10 days, 3 months and 6 months after the surgery. Mean pocket depth distal to mandibular second molar decreased significantly in experimental site compared to the control site. Dentinal hypersensitivity was not seen in the experimental sites. Around 53 % (n=16) of the patients complained of sensitivity around the surgical area at the end of three months. Bone density around the experimental site was found to be denser based on the Bone J analysis. Removal of horizontally impacted mandibular third molar can create a bony defect, which results in soft tissue collapse. Literature supports the use of bone grafts after surgical removal of impacted third molars. Advantages include denser bone, optimum soft tissue closure, and decreased pocket depth distal to mandibular second molar and reduced sensitivity around the operated area. Placement of bone grafts after removal of horizontally impacted mandibular third molars resulted in better soft and hard tissue healing.

Abstract:

New research suggests that treating periodontal disease and infection can affect a patient's glycemic control. It's vital to take a thorough medical history on a diabetic patient before dental treatment, and "know when to modify treatment and when you can do the same treatment that you'd do on a healthy patient." Coronary artery disease (CAD) is one of the major causes of morbidity and mortality worldwide, including low and middle income countries. In recent years, the prevalence of CAD increased rapidly in most of the developing countries, including Bangladesh. The world Health Organization projected that by the year 2020, CAD will be the leading cause of death in developing countries. Diabetes mellitus (DM) is a chronic condition that has become pandemic with increasing prevalence worldwide. Patients with DM often suffer from several oral and dental diseases, such as periodontal diseases, dental caries and tooth loss in addition to the existing complications of the disease. However, many of these traditional risk factors do not explain the pathophysiological etiology of CAD. Recent evidence points out at the possible role of several infectious agents, such as dental infections in the pathogenesis of CAD. The association between CAD, DM and oral health parameters has been explored in many studies in developed countries; however, data from developing countries are limited. We therefore conducted this study to assess the relationship between dental disease with CAD and DM in patients admitted at a tertiary hospital in Bangladesh. The primary goal of health care providers is to motivate patients towards better oral care. The literature relating oral disease with increased risk of systemic diseases provides additional motivation for achieving and maintaining good oral health. Physicians should also consider the oral condition of their patients and refer them to dentists as needed. However, we caution health care providers against creating a panic regarding the consequences of infected teeth. The overall evidence regarding the periodontal-systemic associations is not strong enough, and the associations may or may not be causal. More importantly, one must not recommend extracting infected teeth, based on the periodontal-systemic disease associations, if the teeth do not otherwise warrant extraction because loss of teeth and edentulousness have also been associated with increased risk of systemic diseases. Unnecessary extraction of teeth could do more harm than good. On the other hand, the members of the team responsible for systemic diseases treatment should pay attention to dental care and guidance to dental treatment, especially in the case of adult patients with diabetes, heart diseases, stroke, kidney diseases and pregnant mothers. Periodontal disease can be seen as a complication of other systemic diseases and the importance of its treatment is comparable to the treatment of other complications. Finally, co-operation and consultation between all the members of the medical & dental team responsible for the treatment of patients with systemic diseases is highly recommended.
