Background: The most common dental disease facing the human race is dental caries. For caries, management of early lesions, prevention of initiation, and interruption of progression are desirable. Remineralization is an effective way of preventive management of caries. Aim: To evaluate remineralization efficacy of two different remineralizing agents. Materials and Methods: Forty enamel samples were taken, and they were divided into four groups (n = 10). Demineralization was carried out with Groups A, B, and C. Remineralization was carried out with Groups A and B for 7 continuous days using casein phosphopeptide-amorphous calcium phosphate with fluoride (CPP-ACPF) and calcium sucrose phosphate (CaSP). Group D was kept as positive control with intact enamel without any surface treatment, whereas Group C was kept as negative control with surface demineralization of enamel. Microhardness testing was done using Vickers microhardness tester after 7-day remineralization cycle. Statistical Analysis: One-way analysis of variance and post hoc Tukey tests were performed. Results: Microhardness of CaSP and CPP-ACPF was comparable. Conclusion: Both remineralizing agents showed surface remineralization.

Background: Supragingival plaque control is elementary to the prevention and management of periodontal diseases. Conversely, significant proportions of all individuals fail to practice a high standard of plaque removal. The adjunctive use of chemicals would therefore appear a way of overcoming deficiencies in mechanical tooth cleaning habits. This prospective, randomized positively controlled clinical trial was aimed to evaluate the short-term clinical effects of a licorice oral rinse in the reduction of plaque and gingival inflammation in individuals with gingivitis. Materials and Methods: A total of 104 individuals, 12–15 years of age diagnosed with chronic generalized gingivitis, were selected and randomly divided into two groups: Group 1: chlorhexidine mouthwash and Group 2: licorice mouthwash. Clinical evaluation was undertaken using the gingival index, the plaque index, and bleeding on probing at baseline, 1^st, 2^nd, and 4^th week. Results: Both chlorhexidine and licorice mouthwash showed a significant reduction in plaque and gingival index scores from baseline to 1^st, 2^nd, and at 4^th week. However, the improvement in plaque and gingival index scores were better in chlorhexidine group than herbal mouthwash. Both mouthwashes were found to be equally effective in reducing bleeding on probing. Conclusion: Unlike chlorhexidine mouthwash, licorice mouthwash was not associated with any discoloration of teeth or unpleasant taste and was effective in reducing plaque accumulation and gingival inflammation. However, chlorhexidine still remains a gold standard in reducing plaque, gingivitis, and bleeding on probing.

Cytokines and selective inflammatory mediators play crucial roles in the maintenance of tissue homeostasis. Growth factors such as fibroblast growth factor, platelet-derived growth factor, insulin-like growth factor, and transforming growth factor-β are thought to play important roles in modulating the proliferation and migration of structural cells in the periodontium. These biomolecules have a range of overlapping functions to help engage and control immune and inflammatory responses.

Background: Palmistry in scientific terms is called as "dermatoglyphics" ("derma" means skin and "glyphic" means carvings). Dermatoglyphics as an independent field of study, even though it has a body of theory, methods, and applications; in many respects, it has been used as an adjunct to other disciplines, serving as a vehicle to resolve broader biomedical problems. Many studies have shown that hereditary factors play contributory role in the development of caries risk and malocclusion. This study was done to check whether dermatoglyphics plays a role in malocclusion and dental caries. Aim: To assess whether dermatoglyphics could help predict genetic susceptibility of children to dental caries and malocclusion. Materials and Methods: A total of 300 children aged 6-12 years were screened for dermatoglyphics, dental caries using decayed, missing, and filled teeth and discrete Fourier transform index and malocclusion using Angle's classification. Statistical Analysis Used: To show significant difference between the expected frequencies and the observed frequencies in one or more categories, a Chi-square test was applied. The observed difference was statistically significant and P = 0.03 (<0.05). Results: There was an increased frequency of loop in right hand digit 3 and 5 (middle and little finger) in caries positive participants. Eighty-one percent of loop pattern was observed in digit 5 (little finger) of right hand in Class II malocclusion. Conclusion: Specific fingerprint patterns may be used as a potential noninvasive anatomical tool for mass screening of dental caries and malocclusion and for guiding future research.

Background: Biopsy is an important tool which aids in the diagnosis of lesions ranging from simple non-neoplastic growths to malignancies. The choice of technique depends on factors such as anatomic site and morphology of the lesion. Oral biopsies can be performed using different techniques, in which scalpel biopsy is the conventional method. Punch biopsies are also quite popular because they are safe and can be rapidly performed. However, the above techniques cannot provide hemostasis which is required on highly vascular tissues. As a result, lasers have been gaining popularity. Nevertheless, laser-tissue interactions may produce some artifactual changes, especially at the margins, such as thermal damage and coagulation which may impair the histopathological diagnosis. Aim: The aim of this study was to compare artifacts produced in scalpel, punch, and laser biopsies and to determine the most effective tool of the three in terms of oral biopsies. Materials and Methods: Thirty hematoxylin and eosin stained sections, ten each of conventional scalpel, punch, and laser biopsies, were retrieved from the archives and analyzed for artifacts under a light microscope. Results: There was no statistically significant difference between the three techniques in terms of orientation, crush, and hemorrhage. Both horizontal and vertical splits were seen in scalpel biopsies (70%) while none were present in the other two techniques. Loss of epithelium was maximum with laser biopsies, and thermal damage was also exclusively seen in this technique. Conclusion: Punch biopsy revealed the least number of artifacts. Laser, compared to scalpel and punch, produces artifacts which may render the margins of the lesions uninterpretable.

Introduction: Malignant neoplasm is a major cause of death in developed countries, and its incidence continues to grow, placing a heavy burden on the community. Diabetes mellitus is a serious and leading health problem. Recent studies demonstrated that glucose intolerance was associated with a higher risk of oral cancer death, beginning in the prediabetic range of glucose intolerance. However, few population-based studies, especially in Asian populations, have addressed these issues or have estimated glucose intolerance status. Aim: We undertook this study with the aim of finding out an association between impaired glucose tolerance (IGT) and oral cancer along with finding out prevalence of other risk factors for oral cancer. Materials and Methods: Forty-five cases and 45 controls were selected for the study. Oral glucose tolerance was performed on subjects who satisfied inclusion criteria and were willing to sign informed consent form. Results: Fifty-three percent of the cases had abnormal glucose tolerance when compared to 31% of the controls. Conclusion: To conclude, hyperglycemia (which includes impaired fasting glucose, IGT and diabetes) increases the risk of oral cancer two-fold, however IGT alone as defined by American Diabetes Association does not appear to play a role.

Background: Studying the prevalence of dental caries in a population located in a specific geographic area and the effect of the psychological factors on the people is considered essential to build a database to assess and compare future results of preventive programs and to assess health and social needs of the communities. Aim of this Research: This study aims to study oral health situation using (decayed, missing, and filled teeth [DMFT], plaque index [PI], and gingivitis index [GI]) indices, and the prevalence of posttraumatic stress disorder (PTSD) among 12-year-old children in Damascus, and the effect of PTSD on oral health. Materials and Methods: The sample included 811 children divided into five geographic areas in Damascus. Special questionnaires were used to measure PTSD level, and the oral health status was measured by clinical examination. Results: Data analysis showed that dental caries prevalence was 86%, DMFT value was 3.36. In detail, the D value was 2.86, M value was 0.48, and F value was 0.02. As for PI value, it was 0.79 and GI value was 0.85. The prevalence of PTSD was 91.5%. The study showed a statistically significant relationship between both DMFT and GI values, and PTSD value; however, there was no statistically significant relationship between PI value and PTSD value. Conclusion: The prevalence of poor oral health among 12-year-old children in Damascus schools was high as was the prevalence of PTSD, where we found in our study a statistically significant relationship between oral health index and PTSD.

There is a presence of interarticular space between the bony components of the temporomandibular joint (TMJ), i.e., between articular eminence and glenoid fossa of the temporal bone at the base of the skull and the condylar process of the mandible. The intervening articular disc, together with its attachments, divide the joint into two separate compartments, i.e., upper (superior) and lower (inferior) compartments located above and below the disc, respectively, which are referred as joint spaces. The clinical significance of joint space is of great value; the presence of normal joint space is needed for free movement of condyle along with articular disc. The widening or obliteration of joint space may indicate the involvement of TMJ or its pathology. The joint space configuration is greatly influenced by the glenoid fossa, condyle, and condylar positions within the fossa in TMJ on the right and left sides. The present review work is undertaken primarily including 37 studies from PubMed and Medline databases to reveal the information relating to the joint space, its measurement in normal subjects and TMJ disorder (TMD) patients, its correlation to other factors, and its role in TMDs. The review work would be of help to gain insight to predict the TMDs with respect to joint space morphometrics.

Endo-perio lesions are common clinical finding in the day-to-day dentistry. The treatment approach with respect to periodontal regeneration still remains point at issue. Endodontic treatment not always leads to complete healing of periapical and periodontal tissue. In literature, surgical periodontal intervention along with the use of bone grafts, guided tissue regeneration has been attempted for regeneration. Recently, use of platelet concentrates such as platelet-rich fibrin (PRF) releasing growth factors is extensively used in dentistry for periodontal regeneration. This case report aims at evaluating the efficacy of PRF as regenerative biomaterial in the treatment of Endo-perio lesion.

Squamous odontogenic tumor-like proliferation (SOT-LP) is a nonneoplastic lesion with a histological pattern similar to that of the SOT. This entity is characterized by SOT proliferations isolated in the cyst wall of an odontogenic cyst. This pattern is rarely seen in radicular cysts. The nature of these proliferations is not clear, and there is a varied opinion on the origin. Although it has a benign behavior, it should be differentiated from other aggressive lesions such as intraosseous carcinoma, ameloblastoma, odontogenic keratocyst, and SOT. Knowledge about this unusual lesion can help in the accurate diagnosis and treatment of the patients. Here, we are discussing a rare case of an SOT-LP emerging in a radicular cyst of the maxilla.

The restoration of endodontically treated pulpless teeth is a challenging dental procedure. Post and core is indicated in cases of extensive coronal tooth destruction where additional retention is required. The post is used to retain a core that can be used to retain definitive prosthesis. The choice between using a cast post and a prefabricated post depends on multiple factors such as canal configuration and remaining tooth structure. It has been said that if a canal requires extensive preparation, a well-adapted cast post and core will be more retentive than a prefabricated post that does not match the canal configuration. The cast post and core is fitted to the prepared root canal space and designed to resist torsional forces. However, one drawback of cast post is its tedious and time-consuming wax pattern technique. In this case report, we have used a time saving modified indirect technique for fabricating cast post and core, without the use of any reinforcement, no wax, no pattern resin but only rubber base impression material along with a novel technique of cementation, which utilizes a modified syringe with needle to facilitate even distribution of luting cement within the canal.

Cutaneous sinus tracts of dental origin have been well-documented in the medical literature. However, these lesions continue to be a diagnostic dilemma. A review of several reported cases reveals that patients have had multiple surgical excisions, radiotherapy, multiple biopsies, and multiple antibiotic regimens, all of which have failed, with a recurrence of the cutaneous sinus tract, as the primary etiology was dental that was never correctly diagnosed or addressed. This case report demonstrates the healing of an extraoral draining sinus by means of conventional nonsurgical root canal treatment.

Context: Comparison between antemortem and postmortem dental records and radiographs produces results with a high degree of reliability and relative simplicity. Kvaal et al. introduced an age estimation method by indirectly measuring secondary dentin deposition on radiographs. Cameriere et al., later, put forth a method based on radiographic estimation of pulp/tooth area ratio (AR) in canines. The purpose of the present study was to assess the reliability of various teeth in Kvaal's and Cameriere's methods of age estimation in a specific populace in Central India. Materials and Methods: One hundred and ten patients aged between 15 and 75 years were selected, and the variables P = complete pulp length/root length (from enamel-cementum junction [ECJ] to root apex), r = complete pulp length/complete tooth length, a = complete pulp length/root width at ECJ level, b = pulp/root width at midpoint level between ECJ level and mid-root level, and c = pulp/root width at mid-root level and pulp/tooth AR were recorded as devised in Kvaal's and Cameriere's methods of age estimation, respectively. Statistical Analysis: Statistical analysis was performed with SPSS (version 10.5) package. Mean comparison of morphological variables was carried out using Student's t-test. Intra- and inter-observer reproducibility of measurements was studied using the concordance correlation coefficient. Results: Comparing between Kvaal's and Cameriere's methods, results of the latter method were found to be more accurate in predicting age. Conclusion: Kvaal's method showed varying results for different teeth, but Cameriere's method was more consistent, accurate and showed less variability.

Orthodontic treatment aims at providing an acceptable functional and esthetic occlusion. Tooth movements are strongly related to interactions of teeth with their supportive periodontal tissues. In recent years, due to the increased number of adult patients seeking orthodontic treatment, orthodontists frequently face patients with periodontal problems. Esthetic considerations, such as uneven gingival margins or functional problems resulting from inflammatory periodontal diseases, should be considered in the orthodontic treatment planning. The purpose of this article is to provide a dental practitioner with basic understanding of the interrelationship between periodontics and orthodontics and also to highlight the orthodontics and periodontics interface in clinical practice for optimized treatment outcomes.

Primary failure of tooth eruption (PFE) is defined as a non-syndromic condition in which non-ankylosed teeth fail to erupt fully or partially due to malfunction of the eruption mechanism. Although the eruption path is clear without any mechanical obstruction like cyst or supernumerary tooth, affected teeth fail to erupt. Patients diagnosed with PFE have revealed mutation in the gene encoding the G protein of parathyroid hormone 1 receptor (PTH1R). The condition is characterized by progressive posterior open bite due to involvement of all the teeth distal to the first affected tooth. These teeth fail to respond to orthodontic forces and attempts to correct open bite orthodontically cause the affected teeth to ankylose, thus worsening the open bite. Diagnosis of PFE is critical as management differs from the infra-occluded teeth due to mechanical obstruction or systemic etiology. This review attempts to discuss etiology, clinical features, diagnosis and management of the teeth affected with primary failure of tooth eruption.
