Aims:To assess the reliability of ultrasound imaging coupled with Color Power Doppler for monitoring the healing after nonsurgical endodontic therapy.Materials and Methods:Ten asymptomatic maxillary anterior teeth with approximately similar-sized periapical radiolucent lesions of average dimension 1.3 – 1.9 cm, as observed on an intraoral periapical radiograph, and confirmed by ultrasound was selected for the study. After confirming the diagnosis all the teeth were subjected to nonsurgical endodontic treatment. Postoperative healing was monitored using postoperative subjective feedback, a radiograph, and an ultrasound with a color power doppler, at intervals of six weeks, three months, and six months.Results:Eight among the ten cases studied showed signs of healing, with an ultrasound, as early as six weeks postoperatively, but the radiographs showed a noticeable change only at the end of three months. At the end of the follow-up period of three months and six months, the findings in terms of change in the lesion size were the same with both the radiograph and ultrasound. Ultrasonography was able to predict the healing very consistently at all recall periods from six weeks onward providing vital information such as changes in vascularity and bone formation as compared to radiographs.Conclusions:Ultrasound with Color Power Doppler is an efficient tool for monitoring bone healing as compared to the conventionally employed radiographic method.

Aims:The aim of this study was to assess the outcome of single sitting root canal treatment (RCT) of asymptomatic teeth with periapical cysts.Materials and Methods:Ten maxillary anterior teeth showing periapical lesion on the radiograph was further screened by ultrasound with color power Doppler (CPD) for confirmation of a cyst. The average dimension of the lesions ranged from 1.3 to 1.9 cm. Single sitting RCT was performed on all the selected teeth. Postoperative healing was monitored at regular interval of 3 months, 6 months, and 1 year by using subjective feedback, radiograph, and ultrasound with CPD study.Results:Eight among the ten cases showed either signs of complete healing or healing in progress by the end of 6-12 months.Conclusions:It was observed that single sitting nonsurgical endodontic management of asymptomatic teeth with periapical cyst confirmed by ultrasound was successful in selected cases.

Introduction: Dental caries is a multifactorial disease with the main causative organism being Streptococcus mutans and Lactobacillus spp. “Probiotics” are defined as living microorganisms, principally bacteria, which are safe for human consumption and when ingested in sufficient quantities, have beneficial effects on human health, beyond basic nutrition. These can be used to replace the pathogenic strains of bacteria with the nonpathogenic type in the oral cavity thus can help prevent dental caries. Aims: To evaluate and compare the role of probiotic milk and lozenges on S. mutans and Lactobacillus spp. count on patients who are exposed to probiotics continuously for 7 days. Materials and Methods: Sixty volunteers who were prone to caries were divided into three equal groups. Experimental groups were given probiotics daily for 7 days. In Group A, patients were given milk without any probiotics (control); in Group B, probiotic milk is given; and in Group C, probiotic lozenges are given. Saliva samples were assessed on the 1 st day and after 7 days of intervention. The collected saliva samples were inoculated on the selected culture media and estimation was done by measuring the colony-forming unit. Statistical Analysis Used: Statistical analysis was performed using Student's paired t -test and multiple comparisons by Tukey's honest significant difference test. Results: There was a significant reduction in salivary S. mutans level in both experimental groups after 7 days ( P < 0.05). However, there was no significant difference in Lactobacillus count before and after the intervention. Conclusions: Probiotics have a role in reducing salivary S. mutans count. Probiotics lozenges showed greater efficacy in reducing salivary S. mutans count than probiotic milk.

Aesthetic rehabilitation depends clinical procedures as well as respect for biomemitic principles to obtain the final result. In this case report, two cases are described for the restoration of anterior teeth with porcelain veneers. The porcelain veneers have become a treatment of choice due to the advancements in its bonding procedures as well as its high esthetics. The clinical success of any technique depends on the correct identification of a case for which this treatment is appropriate and the successful execution of the clinical steps involved.
