Introduction: The relationship of the condyle and the mandibular fossa differs in shape with type of malocclusion and skeletal pattern. A review of literature shows till date there are no studies on Temporomandibular Joint (TMJ) condyle-fossa relation to the type of malocclusion based on growth pattern. Computed Tomography (CT) provides optimal imaging of the osseous components of the TMJ. Aim: The purpose of this study was to investigate the condyle-fossa relationship and the dimensional and positional symmetries between the right and left condyles in subjects with normal occlusion and malocclusion in different growth patterns utilizing the CT scans of the TMJ. Materials and Methods: Sixty subjects with age group of 18-30 years were selected for the study. The sample was divided into three groups based on overbite and growth pattern. The groups included 20 subjects with normal occlusion and average growth pattern, 20 patients with horizontal growth pattern and deep bite, 20 patients with vertical growth pattern and deep bite. The depth of the mandibular fossa, the condyle-fossa relationship, and the concentric position of the condyles were evaluated by the images obtained from the sagittal slices. ANOVA was performed to assess the significance. If it was found significant, post-hoc Tukey’s test was performed to see which two groups were statistically significant. Results: No statistically significant difference was found in the anterior joint space and the superior joint space in horizontal and vertical growers with deep bite. Statistically significant (p <0.05) posterior positioning of the condyles was observed (nonconcentric positioning) in vertical growers with deep bite. Conclusion: There is a significant change in the position of the condyle in vertical growers compared to average and horizontal growers. Left condyle is more anteriorly placed than the right condyle in all the three groups. There is no significant change in the vertical depth of the mandibular fossa in all the three groups. © 2017, Journal of Clinical and Diagnostic Research. All rights reserved.

BACKGROUND: The aim of this study was to determine the incidence of different Kennedy's classes of partial edentulism during 18 months period.MATERIALS AND METHODS: Patients were clinically examined for various Kennedy's classes of partial edentulism in the outpatient department (OPD), prosthodontics, GPRDCH, Kurnool (Andhra Pradesh).RESULTS: Of the total 1,420 OPD patients, Kennedy's class III was the most frequent classification encountered (62%) and followed by Kennedy's class I (18%), class II (11%), and class IV (9%) in decreasing order.CONCLUSION: The patients with various Kennedy's classes of partial edentulism can be offered various treatment modalities like removable cast partial dentures, fixed partial dentures, over dentures and implant supported dentures. This study can be crucial for screening the population for incidence of tooth loss as a factor of gender and age. Clinical significance: Tooth loss appears to have an important role in the loss of esthetics and mastication. Study of incidence of various classes of partial edentulism provides clinically useful information for dental training and continuing education.

Aim: The aim of this study was to establish the validity of a new method for evaluating skeletal maturation by assessing the 3rd and 4th cervical vertebrae seen in the cephalometric radiograph. Materials and methods: This study consisted of a sample of 50 patients in the age group of 8 to 14 years of age. Chronologically, they were divided into six groups, based on the age consisting of a minimum of six to a maximum of 10 subjects. All the patients included in the study were females. The selected subjects were clinically examined and then age and date of birth of the patient in years and months was noted. Then lateral cephalograms and hand-wrist radiographs of the patient were taken on the same day with good clarity and contrast. Results: The results suggested that cervical vertebral bone age on cephalometric radiographs calculated with this method is as reliable at estimating bone age as is the Tanner-Whitehouse 3 (TW3) method on hand-wrist radiographs. By determining the cervical vertebral bone age, skeletal maturity can be evaluated in a detailed and objective manner with cephalometric radiographs. Conclusion: The ability to accurately appraise skeletal maturity from cervical vertebral maturation, without the need for additional radiographs, has the potential to improve orthodontic diagnostic and therapeutic decisions. The technique's simplicity and ease of use should encourage this method as a first level diagnostic tool to assess skeletal maturation. Clinical significance: This study revealed that the timing and sequence of ossification of the bones in hand and wrist and cervical vertebrae were able to relate the skeletal development of the various skeletal maturity indicators to a child's development. This method provided a mean with which one can determine the skeletal maturity of a person and thereby determine whether the possibility of potential growth existed.

Background: Predentin, the unmineralized organic matrix is important in maintaining the integrity of dentin. It is usually thick where active dentinogenesis occurs. A wide variation in its thickness is reported. Hence, we determined the variation in predentin thickness at various sites of different age groups. Materials and Methods: 60 freshly extracted teeth (maxillary and mandibular first premolars) were divided into three groups with 20 teeth in each as, Group 1 - teeth with incomplete root formation (age <16 years), Group 2 - teeth with complete root formation (aged between 16 and 30 years), Group 3 - teeth of patients aged above 30 years. The teeth were fixed, decalcified and sections of 6 μ thickness were obtained, and stained with hematoxylin and eosin. The distance between the odontoblastic cell layers of the pulp to the border line of the dentin was considered for the measurement of the predentin thickness. A total of nine sites were considered for each specimen. Results: The present study revealed varied mean predentin thickness at all nine sites in all three age groups. Maximum and minimum thickness was observed at the apex and pulp floor respectively in all three groups. There was a statistical significant difference in predentin thickness between groups 1 and 3 and 2 and 3. Conclusion: The predentin thickness in the first group gradually increased toward the growing end near the apex, while it was relatively constant in the second group and increased overall thickness at all the sites in the third group. A notable finding was a linear increase with age in width of the predentin and the thickness vary as a function of odontoblastic activity during different stages of tooth development.

Context: Microbial contamination, which occurs during dental procedures, has been a potential threat to dental professionals and individuals. There has been a growing concern over the role of bioaerosols in spread of various airborne infections and also to reduce the risk of bioaerosol contamination. Aims: This study was to analyze the number of colony forming units (CFUs) in bioaerosols generated during ultrasonic scaling procedure as well as to evaluate the efficacy of chlorhexidine 0.12% (CHX) preprocedural mouth rinse and high volume evacuator (HVE) in minimizing the bioaerosol contamination. Methods: About 45 individuals were divided into three Groups A, B and C. These groups underwent ultrasonic scaling before and after the use of CHX (0.12%), HVE and combination of CHX (0.12%) and HVE. Bioaerosols were collected on blood agar plates which were incubated at 37°C for 48 h, and the CFUs were counted with manual colony counting device. A comparison was also done between A versus B, B versus C and A versus C groups. Statistical Analysis Used: Student's t-test. Results: We found a significant reduction in the CFUs when CHX (0.12%) preprocedural rinse (P < 0), or HVE (P < 0.001) or combination of both CHX (0.12%) and HVE were employed (P < 0.001). Maximum reduction in CFUs was observed when CHX (0.12%) and HVE were used in combination as compared to their individual use. A moderate significance was seen between A versus C groups but not with B versus C groups and A versus B groups. Conclusion: From our study, we conclude that individual methods such as CHX (0.12%) and HVE were useful to reduce the dental bioaerosols; however, combination of both CHX (0.12%) and HVE is more efficient to reduce dental bioaerosols than individual method. © 2016 Journal of Oral and Maxillofacial Pathology-Published by Wolters Kluwer-Medknow.

This study evaluated the fluoride release and uptake of five common dental restoratives mainly glass ionomer formulations, including a conventional glass ionomer, a relatively new caries stabilization glass ionomer and resin-modified glass ionomer (Fuji II, Fuji VII and Fuji II LC); one compomer (F2000); and one fluoride releasing composite resin (tetric ceram).A total of 12 cylindrical specimens for each of the five materials were prepared following manufacturers instructions for manipulation and immersed independently in 25 ml of artificial saliva and stored as five groups Group I-V. Each group was further divided into three sub Groups A, B, C. The saliva was changed every day in all the specimens. No treatment was carried out for the specimens in subgroup A. The specimens were immersed in 2% sodium fluoride for 1 min before changing saliva in sub group B and the specimens were treated by brushing with a fluoridated dentifrice for 2 min before changing saliva in sub Group C. The fluoride release was evaluated on the 1(st), 7(th) and 28(th) day using a fluoride ion specific electrode.The results demonstrated that the conventional glass ionomer and the recently introduced caries stabilizing glass ionomer showed similar patterns and quantity of fluoride release, which was significantly higher than the resin-modified glass ionomer, the compomer and the composite resin. The resin-modified glass ionomer showed higher fluoride release than the compomer and the composite resin. All the formulations of glass ionomers showed fluoride uptake from the neutral sodium fluoride and the fluoridated dentifrice, by releasing increased amounts of fluoride after treatment, in comparison with the untreated group. However, the compomer and the composite resin showed no fluoride uptake.The fluoride released by the glass ionomer cements (GICs) was found to be highest during the first 24 h and decreased significantly over the 1(st) week with lower levels obtained on the 7(th) and 28(th) day, thus demonstrating the phenomenon of initial burst. The composite resin and compomer used in this study did not show this phenomenon of the initial burst. The resin-modified GICs released more fluoride than the compomer, and the composite resin.

The purpose of this study is to achieve an effective method to remove root canal filling material from the root canal system. The study, thus, aims to evaluate the efficacy of the cleaning ability of two different rotary Ni-Ti systems; ProTaper Retreatment files and RaCe System compared to hand instrumentation with Hedstrom files for the removal of gutta-percha during retreatment.Thirty mandibular premolars with one single straight canal were decoronated and instrumented with ProTaper files and filled with thermoplastic gutta-percha. After 30 days, the samples were divided into three groups and gutta-percha was removed with the test instruments. The postoperative radiographs were evaluated with known criteria by dividing the root into cervical third, middle third, and apical third. The results were tabulated and Statistical Package for Social Sciences Software (IBM Corporation) was used for analysis.The mean deviation of the results were first calculated and then t-test and analysis of variance test (two-tailed P value) were evaluated for establishing significant differences. The rotary instruments were effective in removing the gutta-percha from the canals. Therefore, significant difference was observed between the efficacies of the two rotary systems used. The rotary instruments showed effective gutta-percha removal in the cervical and middle one third. (P > 0.05). However, apical debridement was effective with Hedstrom files.The study concluded the use of both rotary and hand instrumentation for effective removal of gutta-percha for retreatment.

Background: Alkaline phosphatase (ALP) is a hydrolase intracellular enzyme participating in the metabolic processes of cells. Rise in salivary ALP (S-ALP) levels reflects inflammation and destruction of healthy tissues suggesting it as a clinical biomarker. S-ALP is used in analyzing the severity of the disease occurrence in smokers and nonsmokers who are diabetic and nondiabetic. S-ALP levels are analyzed using autoanalyzer in 40 patients who visited our department. Aims and Objectives: To determine the levels of S-ALP in diagnosing potentially malignant conditions and debilitating diseases in early stages of inflammation and altered cellular metabolism. Materials and Methods: The study groups include: (1) Group A - 10 smokers who are diabetic. (2) Group B - 10 smokers who are nondiabetic. (3) Group C - 10 nonsmokers who are diabetic. (4) Group D - 10 nonsmokers and nondiabetic as control. Unstimulated saliva samples are collected and run in auto-analyzer with ALP enzyme reagent to analyze ALP levels. Comparison is made between all the four groups. Results: Results were statistically significant with increased activity of ALP levels in saliva from Group A when compared to Group D. The results are Group A > Group B > Group C > Group D. The results also revealed significant raise in levels of ALP levels in saliva from smokers when compared to diabetes. Thus explaining adverse effects of smoking. Conclusion: S-ALP can be considered to be the biomarker for evaluating adverse effects of smoking, diabetes and other debilitating diseases in early stages. © 2016 Journal of Oral and Maxillofacial Pathology-Published by Wolters Kluwer-Medknow.

Mucormycosis are a group of invasive infections caused by filamentous fungi of the Mucoraceae family. Mucormycosis is essentially limited to immunocompromised patients with poorly controlled diabetes mellitus, hematologic malignancy, organ transplant, chemotherapy, chronic renal insufficiency, malnutrition, deferoxamine therapy and severe burns. The fungi invade arteries leading to thrombosis that subsequently causes necrosis of hard and soft tissues. Here, we present a case report of a 50-year-old diabetic patient with rhinomaxillary form of mucormycosis.
