Despite of many studies conducted on toothbrushes and toothpaste to find out the culprit for abrasion, there is no clear cut evidence to pin point the real cause for abrasion.An in vitro assessment of the role of different types of toothbrushes (soft/ medium/hard) in abrasion process when used in conjunction with and without a dentifrice.Forty five freshly extracted, sound, human incisor teeth were collected for this study. Enamel specimens of approximately 9 mm(2) were prepared by gross trimming of extracted teeth using a lathe machine (Baldor 340 Dental lathe; Ohio, USA). They were mounted on separate acrylic bases. The specimens were divided into three groups, each group containing 15 mounted specimens. Group 1 specimens were brushed with soft toothbrush; Group 2 brushed with medium toothbrush and Group 3 with hard toothbrush. Initially, all the mounted specimens in each group were brushed using dentifrice and then the same procedure was repeated with water as control. Profilometric readings were recorded pre and post to tooth brushing and the differences in readings served as proxy measure to assess surface abrasion. These values were then compared to each other. Kruskal Wallis and Mann-Whitney U test were performed.The results showed that brushing, with water alone, caused less abrasion than when toothpaste was added (p< 0.008). When brushed with water, the harder toothbrush caused more abrasion (higher Ra-value), but when toothpaste was added, the softer toothbrush caused more abrasion (p< 0.001).Besides supporting the fact that toothpaste is needed to create a significant abrasion, this study also showed that a softer toothbrush can cause more abrasion than harder ones. The flexibility of bristles is only secondary to abrasion process and abrasivity of dentifrice has an important role in abrasion process.

Conventional cephalometry is an inexpensive and well-established method for evaluating patients with dentofacial deformities. However, patients with major deformities and in particular asymmetric cases are difficult to evaluate by conventional cephalometry. Reliable and accurate evaluation in the orbital and midfacial region in craniofacial syndrome patients is difficult due to inherent geometric magnification, distortion and the superpositioning of the craniofacial structures on cephalograms. Both two- and three-dimensional computed tomography (CT) have been proposed to alleviate some of these difficulties.The aim of our study is to compare the reliability of anatomic cephalometric points obtained from the two modalities: Conventional posteroanterior cephalograms and 3D CT of patients with facial asymmetry, by comparison of intra- and interobserver variation of points recorded from frontal X-ray to those recorded from 3D CT.The sample included nine patients (5 males and 4 females) with an age range of 14 to 21 years and a mean age of 17.11 years, whose treatment plan called for correction of facial asymmetry. All CT scans were measured twice by two investigators with 2 weeks separation for determination of intraobserver and interobserver variability. Similarly, all measurement points on the frontal cephalograms were traced twice with 2 weeks separation. The tracings were superimposed and the average distance between replicate points readings were used as a measure of intra- and interobserver reliability. Intra-and interobserver variations are calculated for each method and the data were imported directly into the statistical program, SPSS 10.0.1 for windows.Intraobserver variations of points defined on 3D CT were small compared with frontal cephalograms. The intraobserver variations ranged from 0 (A1, B1) to 0.6 mm with the variations less than 0.5 mm for most of the points. Interobserver variations of points between first and second tracings defined on PA Ceph and 3D CT were less than 1.5 mm for all the points. A direct comparison of frontal cephalometry and 3D CT using intraobserver variation for the first observer showed that 3D CT was more reliable than frontal cephalometry for 11 points. Direct comparison of frontal cephalometry and 3D CT for the second observer showed a similar tendency with 14 points significantly more reliable for 3D CT. Comparison of frontal cephalometry and 3D CT using interobserver variation for the tracings showed that 3D CT was more reliable than frontal cephalometry.The study has shown that 3D CT is consistently more accurate and reliable than conventional frontal cephalometry. Unfortunately, the cost of a computerized tomography examination is considerable; this means that, at this stage, its use by surgeons and orthodontists is a last resort.

Objectives: This study aimed to identify the current knowledge, attitude, and perception (KAP) of the future prescribers about antimicrobial (AM) education so that the identified lacunae in the training curriculum can be effectively addressed. Materials and Methods: A questionnaire-based survey was carried out in the 2nd year students of medical and the dental undergraduate (UG) courses at a tertiary care teaching center in Jaipur. Each respondent completed the given questionnaire independently in the allocated time. A scoring system was used to rate the KAP of the respondents as poor, average, or good. Results: Statistically significant differences were found in the KAP of the medical and dental future prescribers (P = 0.0086, 0.0002, and <0.0001 for the KAP, respectively). Conclusion: The attitude of the UG students towards AM education is good, but the deficiencies in the knowledge and perception need to be improved further. Suitable interventions to address these lacunae must be planned. © 2015 Indian Journal of Pharmacology Published by Wolters Kluwer.

Root canal treatment in teeth with incomplete root formation is a challenge. A case of maturogenesis in an immature infected tooth along with probable factors needed for success is discussed. Although clinical and radiographic evidence points to healing and root development, the long-term prognosis and the behavior of tissue occupying the canal space needs further investigation before the procedure can be adopted into routine clinical practice.

Severely resorbed ridges present a great challenge to prosthodontic rehabilitation. Available reconstructive options include autologous/alloplastic augmentation with questionable results, or regeneration of new bone under gradual and controlled tension using distraction osteogenesis. This study focused on use of distraction osteogenesis for the treatment of vertically deficient alveolar ridges to assess its feasibility and outcome.Alveolar distraction osteogenesis (ADO) was studied at 10 different intra-oral, partial or complete edentulous sites. After a latency period of 5 days, distraction was carried out for 6-7 days at the rate of 0.5 mm every 12 hours (1 mm/day). Distractor was removed after a consolidation period of 12 weeks.The mean height gained at the 10 intra-oral sites was 4.8 mm with standard deviation of 0.056. The mean follow-up period was 2 years. Complications of therapy included hardware failure, wound gape and extra-oral scar. The overall complication rate was 10%.Distraction osteogenesis is a promising option to aid uneventful prosthodontic rehabilitation of severe vertically resorbed alveolar ridges.

Lasers have made tremendous progress in the field of dentistry and have turned out to be crucial in oral surgery as collateral approach for soft tissue surgery. This rapid progress can be attributed to the fact that lasers allow efficient execution of soft tissue procedures with excellent hemostasis and field visibility. When matched to scalpel, electrocautery or high frequency devices, lasers offer maximum postoperative patient comfort.Four patients agreed to undergo surgical removal of benign lesions of the oral cavity. 810 nm diode lasers were used in continuous wave mode for excisional biopsy. The specimens were sent for histopathological examination and patients were assessed on intraoperative and postoperative complications.Diode laser surgery was rapid, bloodless and well accepted by patients and led to complete resolution of the lesions. The excised specimen proved adequate for histopathological examination. Hemostasis was achieved immediately after the procedure with minimal postoperative problems, discomfort and scarring.We conclude that diode lasers are rapidly becoming the standard of care in contemporary dental practice and can be employed in procedures requiring excisional biopsy of oral soft tissue lesions with minimal problems in histopathological diagnosis.

The use of orthodontic treatment in adult patients is becoming more common and these patients have more specific objectives and concerns related to facial and dental aesthetics, specially regarding duration of treatment. Dentists are on the lookout for techniques for increased efficiency in orthodontic treatment. Alveolar Corticotomy-assisted orthodontic treatment is a recent orthodontic technique that is recently gaining wide acceptance and is recorded as effective means of accelerating orthodontic treatment. A 17-year-old female patient was undergoing orthodontic treatment for the past one year but during her space closure, a visual examination confirmed a buccal thickening that was encountered in the buccal plate between premolars and canine. Periodontal intervention involved elective alveolar decortication in the form of dots performed around the teeth that were to be moved. This was carried out to induce a state of increased tissue turnover and a transient osteopenia, which further helps in faster rate of orthodontic tooth movement. Its main advantages are reduction of treatment time and post-orthodontic stability.

There is a growing concern about ever-burgeoning list of irrational fixed dose combinations (FDCs) which have flooded pharmaceutical market recently in India. Till date no structured study has evaluated the level of understanding among the dental clinicians and residents about these concepts. The present study is designed to fulfil that lacuna.To evaluate the knowledge, attitude and practice, regarding the use of FDCs by the dental residents and dental clinicians in a tertiary care teaching dental hospital.The present study was carried out among postgraduate students and dental clinicians working at Rajasthan Dental College, a tertiary care teaching dental hospital, in Jaipur, India. Sixty residents and 77 dental clinicians from the departments of Orthodontics, Prosthodontics, Oral Medicine, Periodontology, Conservative Dentistry & Endodontics, Oral & Maxillofacial Surgery, Pedodontics who gave their informed consent were enrolled. A prevalidated questionnaire regarding knowledge, attitude and prescribing practice of fixed dose combinations was filled up. Data was analysed with suitable statistical tests.Out of the 60 residents and 77 dental clinicians recruited for the study, none of them were aware about all of the advantages and disadvantages of FDCs. On an average, only 47% of residents and 61% dental clinicians were aware of FDC included in WHO Essential Medicines List (EML). Only 47% residents and 58% dental clinicians could recall a single banned FDC in India. Common sources of information about FDCs were Monthly Index of Medical Specialities (MIMS), medical representatives and internet. The most commonly prescribed irrational FDC was diclofenac + paracetamol combination, 42% residents and 41% dental clinicians and residents believed that regular Continuous Medical Education (CMEs) stressing upon rational use of medicine could reduce the magnitude of this problem.It is the need of the hour to reduce the magnitude of this problem by sensitizing dental residents and prescribers regarding the efficacy, safety, suitability, rationality and cost benefit of FDCs available for patient use.

To compare the effect of honey, chlorhexidine mouthwash and combination of xylitol chewing gum and chlorhexidine mouthwash on the dental plaque level.Ninety healthy dental students, both male and female, aged between 21 to 25 years participated in the study. The subjects were randomly divided into three groups, i.e. the honey group, the chlorhexidine gluconate mouthwash group and the combination of xylitol chewing gum and chlorhexidine (CHX) mouthwash group. The data was collected at the baseline, 15(th) day and 30(th) day; the plaque was disclosed using disclosing solution and their scores were recorded at six sites per tooth using the Quigley and Hein plaque index modified by Turesky-Gilmore-Glickman. Statistical analysis was carried out later to compare the effect of all the three groups. P 0.05 was considered as statistically significant.Our result showed that all the three groups were effective in reducing the plaque but post-hoc LSD (Least Significant Difference) showed that honey group and chlorhexidine + xylitol group were more effective than chlorhexidine group alone. The results demonstrated a significant reduction of plaque indices in honey group and chlorhexidine + xylitol group over a period of 15 and 30 days as compared to chlorhexidine.
