The aim of our study was to evaluate the advantages and disadvantages of three-dimensional (3D) plating system in the treatment of mid-face fractures.Thirty mid-face fractures in 18 patients at various anatomic locations were treated by open reduction and internal fixation using 3D plates. All patients were followed at regular intervals of 4th, 8th and 12th weeks respectively. Patients were assessed postoperatively for postoperative complication and occlusal stability. The incidence of neurosensory deficit, infection, masticatory difficulty, nonunion and malunion was also assessed.A significant reduction in fracture (72.2%) and occlusal stability (72.2%) was seen. The overall complication rate was (16.6%) which included two patients who developed postoperative paresthesia of lip, three patients had infection and two cases of masticatory difficulty which later subsided by higher antibiotics and 4 weeks of MMF. No evidence of nonunion and malunion was noted.Single 3D titanium plates with 1.7 mm diameter holes and 1.7 mm screws were reliable and an effective treatment modality for mid-face fracture.Because of unique biogeometrical design owing to lesser amount of hardware material (fixation device) resulting into increased stability, the fixation in mid-face fractures is better in comparison to conventional 1.5 mm miniplate fixation.

Ameloblastoma remains an enigmatic group of oral tumors, inspite of being so frequently encountered and widely discussed. Out of the total ameloblastomas reported, 81% cases have been in the mandible, of which 70% are in the molar-ramus area. We report two cases of ameloblastoma with misguiding radiographic and clinical pictures, which made us ponder that common oral lesions are sometimes, the most tough and confusing to diagnose.

Candida is the shortened name used to describe a class of fungi that includes more than 150 species of yeast. In healthy individuals, Candida exists harmlessly in mucus membranes such as your ears, eyes, gastrointestinal tract, mouth, nose, reproductive organs, sinuses, skin, stool and vagina, etc. It is known as your "beneficial flora" and has a useful purpose in the body. When an imbalance in the normal flora occurs, it causes an overgrowth of Candida albicans. The term is Candidiasis or Thrush. This is a fungal infection (Mycosis) of any of the Candida species, of which Candida albicans is the most common. When this happens, it can create a widespread havoc to our overall health and well-being of our body.

Many oral squamous cell carcinomas (OSCCs) arise within regions that previously had premalignant lesion. Early diagnosis and prompt treatment of premalignant lesions offers the best hope of improving the prognosis in patients with OSCC. Exfoliative cytology is a simple and non-invasive diagnostic technique that could be used for early detection of oral premalignant and malignant lesions. This study was undertaken to evaluate the quantitative changes in nuclear area (NA), cytoplasmic area (CA) and nuclear-to-cytoplasmic ratio (NA/CA) in cytological buccal smears of oral leukoplakia with dysplasia (OLD) and OSCC patients while comparing with normal healthy mucosa.A quantitative study was conducted over 90 subjects including 30 cases each of OLD, OSCC and clinically normal oral mucosa. The smears obtained were stained with Papanicolaou (PAP) stain and cytomorphological assessment of the keratinocytes was carried out. The statistical tools included arithmetic mean, standard deviation, Chi-square test, analysis of variance, Tukey multiple comparison. P < 0.001 was considered as significant.The mean NA of keratinocytes in the normal mucosa was 65.47 4.77 m(2) while for OLD it was 107.97 5.44 m(2) and 139.02 8.10 m(2) for that of OSCC. The differences show a statistically significant increment in NA (P < 0.001). There was significant reduction (P < 0.001) in the CA of keratinocytes from OSCC when compared with those from smears of OLD and normal mucosa with the values of 1535.80 79.38 m(2), 1078.51 56.65 m(2) and 769.70 38.77 m(2) respectively. The NA/CA ratio in the smears from normal oral mucosa, OLD and OSCC showed a mean value of 0.043 0.004, 0.100 0.008, 0.181 0.015 respectively with a significant difference among the groups (P < 0.001).Evaluation of nuclear and CA of keratinocytes by cytomorphometry can serve as a useful adjunct in the diagnosis and prognosis of a dysplastic lesion which may lead to OSCC.

Candidiasis, a common opportunistic fungal infection of the oral cavity, may be a cause of discomfort in dental patients. There are few local factors that make the oral tissues susceptible to Candida infection. These factors include acid saliva, xerostomia, night use of prosthetic dentures, tobacco, carbohydrate rich diets and patients that receive radiotherapy and chemotherapy in maxillofacial structures. Maintenance of oral hygiene and early diagnosis of this condition is very important. © 2014 Indian Journal of Public Health Research and Development. All rights reserved.

Background: Lichen planus (LP) is a chronic mucocutaneous disease of uncertain etiology. Recent reports suggest that LP is an extrahepatic manifestation of Hepatitis C infection. Objective: To determine the association of Hepatitis C virus (HCV) infection with oral LP and to study the tests of liver function in patients with oral LP. Study Design: A cross-sectional case-control study was carried out on 25 patients with oral LP and an equal number of controls. The study was conducted in the outpatient department of a dental college for a period of six months between January and June 2008. The sera of the patients and controls were tested for HCV ribonucleic acid (RNA) using reverse transcription primed-polymerase chain reaction and liver function tests (bilirubin, transaminases, and alkaline phosphatase). Results: Of the 25 patients with LP, three (12%) had HCV infection. None of the controls had HCV RNA positivity (P = 0.2347). Oral LP patients had higher serum bilirubin and transaminases when compared with controls (P < 0.05). However, there was no significant difference in alkaline phosphatase. HCV-positive and -negative patients did not differ significantly in liver function tests. Conclusions: An increased prevalence of HCV infection was seen in oral LP patients. Our findings support a possible etiological association between these two diseases.

India has an assortment of tribal population living in isolated pockets, and the Santhals are numerically predominant in Jharkhand. This study was aimed at assessing the oral health status and treatment needs of Santhals residing in Dhanbad, Jharkhand.A cross-sectional survey of 921 Santhals of Topchanchi Block was conducted. A modified World Health Organization (WHO) Oral Health Assessment Form (1997) was utilized and examined according to the WHO methodology (1997). The recorded data was statistically analyzed using the Statistical Package for the Social Sciences version 15.Based on the occupation, it was seen that 620 (67.3%) participants practiced agriculture and 206 (22.4%) worked as laborers. The mean decayed missing filled tooth (score was 3.56 1.93 in 2-5-year-old participants. In the higher age groups of 35-44 and 65-74 years, the scores were 5.21 2.34 and 7.42 4.29, respectively. Participants with bleeding gums were predominantly seen in the age group of 35-44 years (0.91 0.08). Approximately 138 (54.1%) participants had a loss of attachment of 4-5 mm in the 35-44 year age group. In the 13-15-year-old age group, 0.14 0.05 teeth needed two surfaces fillings. A total of 118 (12.8%) participants needed one-unit prosthesis in the upper jaw.This study showed that a majority of Santhal tribals used twigs to routinely clean their teeth. Poor oral hygiene and periodontal status was seen among the tribes.

This study was carried out to compare the different techniques of placement of polyethylene fibre (Ribbond) on reinforcement of endodontically treated teeth with MOD cavities in vitro. Forty extracted human premolars were randomly assigned to four groups (n=10). Teeth in Groups I-IV received root canal treatment and a MOD cavity preparation, with gingival cavosurface margin 1.5mm in coronal to cementoenamel junction. Group I served as no fibre group, Group II as occlusal fibre group, Group III as base fibre group and Group IV as dual-fibre group (occlusal and base both). Subsequent to restoring with composite resin and thermocycling, a vertical compressive force was applied at a cross-head speed of 0.5mmmin(-1) using universal testing machine until fracture. Data were analysed using one-way analysis of variance and Tukeys posthoc tests. Fracture resistance was significantly highest in dual-fibre group (P<0.001) as compared with other groups. The highest favourable fracture rate was observed in the base fibre group (70%). This study concluded that the use of polyethylene fibre inserted over or under the restoration significantly increased the fracture strength of the root canal-treated teeth and maximum fracture resistance was observed when cavity was restored using dual-fibre technique.

To evaluate the antimicrobial activity of different concentrations of Matricaria chamomilla and Chlorhexidine gel against Candida albicans and Enterococcus faecalis.The agar diffusion test was used to evaluate the antimicrobial activity of 15%, 25% Matricaria chamomilla in aq. base and 2% chlorhexidine gel against C. albicans (ATCC 24433) and E. faecalis (ATCC 24212) strains. Vancomycin was used as the positive control for E. faecalis and fluconazole for C. albicans . The agar plates were incubated at 37C for 48 h after which the zone of inhibition were measured separately for each material. Data thus obtained were statistically analyzed using the Wilcoxon rank-order test.2% chlorhexidine showed maximum inhibitory zone for C. albicans (33.26 mm) and E. faecalis (24.54 mm). 25% Matricaria showed zones of 24.16 mm and 20.62 mm for C. albicans and E. faecalis, respectively. 15% Matricaria did not show any antimicrobial activity (0 mm).The results of the current in vitro study suggest that 25% Matricaria can be used as an antimicrobial agent, but it is less effective than 2% chlorhexidine gluconate gel against C. albicans and E. faecalis. Matricaria at a lesser concentration of 15% aq. base is ineffective against both the microorganisms.

As civilization has progressed, there has been continued refinement of materials available for dental practice. The applications of resins have been extended to increased practical uses in numerous areas of prosthetic and restorative dentistry. Certain significant alterations in the technique of manipulation and nature of the dental product have influenced the range of application in dentistry. The present study was done to measure and compare the fracture strength of heat polymerized poly-methyl-methacrylate (PMMA) resin reinforced with fibers of glass, polyaramid, and nylon.The present study was conducted in vitro on 40 PMMA denture base resin specimens. Specimens were divided into four subgroups with ten specimens each and tested for transverse strength using universal testing machine.In group I, the transverse strength mean value was 67.82 MPa. In group II, the transverse strength mean value was 59.47 MPa. In group III, the transverse strength mean value was 66.87 MPa, while in group IV, the transverse strength mean value was 66.47 MPa.Incorporation of 4% weight glass fibers in loose form significantly increased the transverse strength of denture base PMMA, while 4% of polyaramid fiber in random distribution significantly increased the transverse strength of denture base PMMA.
