This case report describes the Revascularization of a Permanent Immature Mandibular Premolar with Pulp Necrosis and apical periodontitis. Access opening was done & the canal was disinfected with copious irrigation using 2.5% NaOCl and triple antibiotic paste (Ciprofloxacin, Metronidazole, and Minocycline) as intracanal medicament. After the disinfection protocol is complete, it is followed by revascularization procedure. The apex was mechanically irritated to initiate bleeding into the canal to produce a blood clot to the level just below the level of cementoenamel junction. Mineral trioxide aggregate was placed over the blood clot followed by bonded resin restoration above it. After one year follow up; the patient was asymptomatic, no sinus tract was evident. Apical periodontitis was resolved, and there was radiographic evidence of continuing thickness of dentinal walls. © 2014,Journal of Clinical and Diagnostic Research All Rights Reserved. Source

Objective: To describe the status of dental caries in a sample of Iranian adolescents aged 14 to 18 years in Qazvin, and to identify caries-related factors affecting this group. Study design: Qazvin was divided into three zones according to socio-economic status. The sampling procedure used was a stratified cluster sampling technique; incorporating 3 stratified zones, for each of which a cluster of school children were recruited from randomly selected high schools. The adolescents agreed to participate in the study and to complete a questionnaire. Dental caries status was assessed in terms of decayed teeth (DT), filled teeth (FT) and decayed, missing and filled teeth (DMFT). A multivariate regression analysis was used to determine statistically significant associations between DMFT and other variables. Results: The study sample comprised 380 adolescents, 188 (49.5%) being male. The mean age of the adolescents was 15.42 (SD= 1.1) years, and the mean DMFT was 2.61 (SD=1.89). Boys had significantly higher DMFT scores than girls (P<0.05). The multivariate regression analyses revealed a significant relation between high DMFT scores and such variables as increasing age, male gender, lower levels of parental education, higher family income, lower frequency of tooth brushing and dental flossing, having a history of no visits to the dentist, and bad perception of own oral health. Conclusions: The present study reveals that Iranian adolescents have a poor oral hygiene, as very few subjects brush and floss their teeth on a regular basis. Although the incidence of caries was found to be moderate, it was influenced by demographic factors such as age and gender in addition to socio-behavioral variables such as fami-ly income, the level of education attained by parents, the frequency of dental brushing and flossing, and both the frequency and type of visit to a dentist. © Medicina Oral S.

Langerhans cells (LCs) were first described by Paul Langerhans, in 1868, as dendritically shaped cells, which were located in the squamous epithelia of epidermis. Later on, these cells were identified in all stratified squamous epithelium of mammals. Dendritic cells (DCs) play an important role in local defense mechanisms in the epithelium. LCs are situated usually in the suprabasal layer of stratified squamous epithelia of oral mucosa and epidermis of skin. They constitute 3% of the cell population in epidermis. LCs are thought to act as antigen presenting cells (APCs) during initiation of immune responses. With the help of APCs, the lymphocytes are able to recognize and respond to specific microbes. In this paper we have reviewed the origin, distribution, demonstration and mechanism of action of LCs and their role in different pathological conditions. Source

To determine the effectiveness of aloe vera gel in the treatment of oral lichen planus when compared with triamcinolone acetonide. A randomized, double-blind, clinical trial was designed. The study sample constituted 40 patients (23 males and 17 females) who were randomly divided into two equal groups. Group A patients received aloe vera gel, while group B patients received triamcinolone acetonide. Forty patients were included in the study. Most of the sample presented with erosive (n = 18) and atrophic (n = 14) variants of oral lichen planus. When clinical signs and symptoms were observed after 8 weeks of therapy, it was determined that aloe vera gel was more effective than triamcinolone acetonide in the treatment of oral lichen planus. Aloe vera gel can be considered a safe alternative treatment for oral lichen planus. Source

To determine the influence of smoking on the blood and salivary superoxide dismutase levels among smokers, and to demonstrate the significance in alterations in the levels of superoxide dismutase in association with patient age, periodontal disease status, and duration and smoking frequency. Sixty healthy male patients (aged 20-60 years) constituted the target population. Blood and saliva samples were collected, and the periodontal index was measured using a Community Periodontal Index probe. Blood and salivary superoxide dismutase levels were calculated with the reagents prepared, and values were measured in a UV spectrophotometer. There was a significant decrease in mean superoxide dismutase levels with an increase in age and smoking duration and frequency (0.23-0.05 U/mL). There was a range of 0.31-0.06 U/mL variation in the mean superoxide dismutase levels as the periodontal disease condition deteriorated. There was a significant reduction in the superoxide dismutase levels in the blood and saliva of smokers with increased duration and frequency of smoking, and as the periodontal disease condition worsened. Thus, this study emphasizes the importance of saliva as an easy, non-invasive procedure in the diagnosis of patients who are more prone to precancerous lesions and conditions, and its importance in patient education and motivation programs for smoking cessation. © 2011 Blackwell Publishing Asia Pty Ltd.
