Shapiro-Wilk's test and Wilcoxon test were applied to the data collected for statistical analysis. Results There was a statistically significant increase with ALP levels, orthodontic plaque index score, gingival index score, and bleeding on probing index score. A statistically significant reduction was seen with respect to levels of calcium and pH. Conclusion Maxillary canines and lateral incisors were the most affected teeth with WSLs (78.84%). There is a need for more stringent prevention programs and oral hygiene practices prior to initiation of orthodontic treatment and also during orthodontic treatment.

Chlorhexidine (CHX) is considered as the gold standard in chemical plaque control, but the main concern is about its fibroblast cytotoxicity. Curcumin, a lipophilic polyphenol, may offer as a promising antiplaque agent. This study was conducted to compare the effect of curcumin (0.003%, 0.03%, 0.06%, 0.1%, and 0.12%) and CHX (0.03%, 0.06%, 0.1%, 0.12%, and 0.2%) on gingival fibroblast cell viability and wound healing at different time periods (1, 2, 4, 6, 8, and 10 min). Materials and Methods The minimum inhibitory concentration (MIC50) was determined before the evaluation of cytotoxicity and wound healing property. 3-(4,5-Dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide assay and morphological examination by direct invert microscopy were carried out to determine cytotoxicity. Wound healing was evaluated by scratch wound assay. Results and Discussion The MIC50 of CHX and curcumin was at 0.1% and 0.003%, respectively. The mean percentage of fibroblast viability at different concentrations of CHX and curcumin at each time period showed a significant difference. Curcumin exhibited less cytotoxicity as compared to CHX at all concentrations and at varying time periods. There was a significant difference between mean percentage of fibroblast viability at MIC50 of CHX (0.1%) and curcumin (0.003%) at different time periods. The difference between percentage wound healing at antibacterial concentrations of CHX and curcumin at varying time periods was significant. Conclusion The antibacterial concentration of curcumin (0.003%) exhibits less fibroblast cytotoxicity and excellent wound healing property as compared to CHX. Curcumin may offer as a promising chemical plaque control agent which is less cytotoxic, cost-effective, safe, easily available, and with a possibly beneficial effect on wound healing.

Latest diagnostic technique such as matrix-assisted laser desorption/ionization time of flight mass spectrometry (MALDI-TOF) is increasingly being used for accurate identification of bacteria. This study was undertaken to evaluate the MALDI-TOF MS technique to identify bacterial pathogens from dental plaques in subjects with primary, mixed, and permanent dentition. Materials and Methods The study included 150 subjects of different age groups and were divided into three groups - Group A Subjects with primary dentition (n = 50), Group B Subjects with mixed dentition (n = 50), and Group C Subjects with permanent dentition (n = 50). Subgingival dental plaque samples were collected from buccal and lingual surfaces of premolar and molar teeth. Clinical parameters such as gingival index were recorded. Samples were cultured in routine aerobic and anaerobic medium. Bacterial growths were assessed bn Society of Periodontology.A solid career plan is crucial as it can provide a roadmap to the future. The motivating factors for selecting any career are complex, and periodontics is no exception. Periodontics is a dynamic profession that includes sophisticated treatment planning and a wide variety of treatment modalities ranging from conventional to advanced therapies. It is a unique branch of dentistry that enables both saving teeth and also replacing them in an effective way with implants. The purpose of this article is to provide an overview of various career opportunities for a periodontist. Career options in periodontics are manifold and diverse, enabling a periodontist a professionally gratifying and secure lifestyle. Selleck BX-795 Future of the profession of periodontics appears exciting and rewarding but is not likely to happen without great effort and challenges. However, periodontics is not a static field and continues to evolve leaving a periodontist with no dearth in career opportunities.

When comprehension breaks down due to an inconsistency either at the word-level (e.g., due to an unfamiliar word) or at the sentence-level (e.g., due to contradictory information), readers may identify the misunderstanding and take steps to regulate their comprehension. In the current study, we utilized two eye-movement tasks (one newly developed) to examine comprehension monitoring in third through fifth grade students (n = 123), when confronted with word- and sentence-level inconsistencies, by measuring the amount of time they read (gaze duration) and reread the target inconsistent words. We investigated how this skill may be associated with individual differences in age, reading comprehension ability, and vocabulary knowledge. The results showed that generally, all students detected the word-level inconsistencies, indicated by longer gaze durations, and attempted to regulate their comprehension after detecting both word- and sentence-level inconsistencies, as indicated by more time spent rereading. Students with stronger reading comprehension (when controlling for their vocabulary), and stronger vocabulary knowledge (when controlling for their reading comprehension) were more likely to attempt regulating their comprehension. In general, the difference between the control words and the inconsistent words was smaller for third graders and larger for fourth and fifth graders, which we argue indicates greater levels of comprehension monitoring - specifically employing repair strategies. With eye-tracking technology becoming more accessible, these tasks may be useful in assessing children's reading processes to better understand at which level of comprehension monitoring they may be struggling, which in return will allow us to develop more individualized instruction for all readers.
