Purpose: To evaluate the changes in mutans streptococci counts in saliva after short term probiotic intervention and its delayed effects on salivary mutans streptococci count. Methods: 40 children in the age group of 12-15 years with medium to high caries activity were randomly divided into Group I Control (plain milk group) and Group II Experimental (probiotic supplemented milk group). Duration of the study was 9 weeks; which was evenly divided into three phases: baseline, intervention and post-treatment period; each phase consisting of three weeks. After baseline period of 3 weeks, children in group I were given plain milk and in group II milk containing probiotic Lactobacillus rhamnosus hct 70 for 3 weeks; followed by a 3 weeks follow up period. After every phase saliva samples were collected to estimate salivary mutans streptococci counts. Results: The difference in the post follow up mutans streptococci count of group I and group II, was highly significant with p value < 0.001. In the control group, the difference in the mean salivary baseline, post treatment and post follow up mutans streptococci counts was not statistically significant (p = 0.001). In the experimental probiotic group, the difference in mean salivary baseline, post treatment and post follow up mutans streptococci counts was statistically highly significant ( p = 0.000, p ≠0.001). Conclusions: Statistically significant reduction in salivary mutans streptococci counts immediately after consumption of probiotic Lactobacillus rhamnosus hct 70 containing milk suggest a beneficial effect of probiotic Lactobacillus rhamnosus hct 70 in the prevention of dental caries.

To check the reliability of panoramic radiographs in assessing mesiodistal angulations while considering the true long axes of teeth in relation to a horizontal reference archwire. A clear anatomical typodont with removable teeth was used with 0.8-mm chromium steel balls glued over the incisal/occlusal and apical/furcal portions of teeth to serve as reference markers for representing true long axes of teeth on radiographs and photographs. A photograph of each tooth was taken with a particular technique to serve as a medium through which to measure true mesiodistal angulations of teeth. Only overall maxillary teeth angulations significantly correlated to true mesiodistal angulations. Radiographic relationship of the long axes of adjacent teeth (convergence or divergence) in the mandibular as well as the maxillary arch did not show any significant correlation to true degree of convergence or divergence and displayed a tendency to accentuate the maxillary canine to premolar divergence and mandibular lateral incisor to canine convergence. Panoramic radiographs provide a poor representation of the mesiodistal angulations of teeth and require cautious use with clinical judgment and adjunctive procedures to ascertain root angulations.

Periodontitis is a chronic inflammatory disorder characterized a complex interaction between periodontopathic bacteria and the host inflammatory response resulting in release of pro-inflammatory cytokines leading to the destruction of periodontal tissues and alveolar bone. One of the important host factors involved in periodontal diseases is matrix metalloproteinases (MMPs), which is responsible for collagen and extracellular matrix (ECM) degradation of the periodontal tissues. MMPs comprise a family of around 25 members broadly categorized into six groups, which are involved in various physiological and pathological conditions. The activities of MMP are generally balanced by endogenous inhibitors such as tissue inhibitors of metalloproteinase (TIMP), and any imbalance between MMP and TIMP levels plays an important role in the disease progression. Assessment of MMP in tissues, GCF, and saliva may serve as an important biomarker in diagnosis of periodontal diseases and also for prognostic follow-up. Targeted therapy aimed at reducing effects of MMP may serve as a useful adjunct for treatment of periodontitis. This review provides an overview of MMP and its role in various physiological and pathological conditions with emphasis on its association with periodontal diseases. A note on its inhibitors and therapeutic importance is also provided. © 2014 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd 206 September 2014.

Glandular odontogenic cysts (GOCs) are rare intrabony solitary or multiloculated cysts of odontogenic origin. The importance of GOCs lies in the fact that they exhibit a propensity for recurrence similar to keratocystic odontogenic tumors and that they may be confused microscopically with central mucoepidermoid carcinoma. Thus, the oral and maxillofacial radiologists play an important role in definitive diagnosis of GOC based on distinctive cases; though they are rare. In large part, this is due to the GOC's complex and frequently non-specific histopathology. This report describes a case of GOC occurrence in the posterior mandibular ramus region in a 17-year-old female, which is a rare combination of site, age, and gender for occurrence. © 2014 by Korean Academy of Oral and Maxillofacial Radiology.

Dentomaxillofacial Radiology | Year: 2011

X-rays were discovered in 1895 and since then much has been written about Wilhelm Roentgen and the events surrounding the discovery. However, there have been only scattered references in the literature about the early workers who dedicated their life, and death, to X-rays. Radiology has come of age since then. Large exposure times have been reduced to milliseconds and there has been a change from analogue to digital. The advent of new and rapidly developing modalities and the ubiquitous presence of cone beam CT (CBCT) highlight the need to remember the early victims of X-rays, especially with the lack of universal guidelines for taking a CBCT scan. The aim of this article is to alert the oral radiologist to exposing patients irrespective of need, and to pay respect to the victims on the 116th anniversary of the discovery of X-rays. © 2011 The British Institute of Radiology.

Objective: A study was carried out to investigate the rationale that use of a thyroid collar (TC) in cephalometric radiography hampers the diagnostic and descriptive quality of lateral cephalogram. Methods: A randomized observer blinded study was designed. The study consisted of two groups. The first group data were retrieved from the oral radiology archival system having lateral cephalogram without a TC. The second group was selected from the oral radiology department of patients where lateral cephalogram was taken using a TC. Lateral cephalogram was taken on direct digital system, the Kodak 9000 unit (Eastman Kodak, Rochester, NY). 2 observers blinded about the aim of the study were appointed to identify 15 sets of landmarks on the lateral cephalogram. Interobserver variance was also analysed for the study. Results: 50 lateral cephalograms in each group were studied. Out of 15 sets of landmarks, 12 were identified consistent with the TC group. Three landmarks, namely the hyoid bone, second cervical vertebra and third cervical vertebra could not be identified on the TC group. There was no significant difference in the interobserver markings on lateral cephalogram. Conclusions: TCs do mask a few landmarks on the lateral cephalogram. These landmarks are mainly used for analysis of skeletal maturity index (SMI). Lead TCs are probably the most convenient and easily available means to protect the thyroid from unwanted radiation while taking lateral cephalogram. It is therefore encouraged to use a TC during routine cephalometric radiography where SMI information is not needed. © 2011 The British Institute of Radiology.

Women in Indian culture have a paradoxical status: on the one hand, goddesses are worshipped for power and prosperity; on the other hand, working women face challenges due to age-old beliefs and sociocultural norms. With 60% of the students enrolled in undergraduate dental education currently being women, there is a need to study the challenges these women are facing and how they tackle them. The aim of this survey study was to assess the barriers women dentists face in career advancement and how successfully they balance the personal, professional, and social aspects of their lives. Questionnaires, consisting of four qualitative and 24 quantitative items, were distributed to 500 women dentists: postgraduate residents and faculty members in dental colleges of Mumbai and Navi Mumbai, as well as private dental practitioners. Of the 500 women, 210 returned the survey, for an overall response rate of 42%. The results showed that 95% of the respondents believed they successfully balance the various spheres of their lives, but the most common challenges they faced continued to be traditional gender bias, dual professional and home responsibilities, and preconceived ideas about women.

Introduction: The mental foramen shares its significance in various fields of dentistry. Being a strategically eminent landmark, an understanding of the variation of its position is important Aim: To radiographically evaluate frequently occurring position of mental foramen and its distance with reference to the lower premolars and the lower border of mandible on standardized panoramic radiographs. Methods: The inferior alveolar canal, upto the mental foramen, was traced over 300 orthopantomographs (OPGs) which were selected by using specific criteria. The mandibular plane and the long axis of the premolars were used as references to measure perpendicular distance of foramen. Results: The most common position was found to be between the two premolars (63% cases), which scaled approximately 15.46mm above the lower border of the mandible, with an average proximity to the 2nd premolar (5.51mm) than the 1st premolar (8.21mm). This was followed by position behind the second premolar, which scored 20.67%. Both the foramina were noted in the same vertical plane of reference, and they showed bilateral occurrence of the most common position of the mental foramen, with respect to 45.67% cases. Conclusion: The most common location was reported to be between the two premolars, with a definite bilateral symmetry on both left and right sides. No gender preferences were observed. An average distance of 15mm from the lower border of the mandible was calculated.

The clinical use of information technology in the dental profession has increased substantially in the past 10 to 20 years. In most developing countries an insufficiency of medical and dental specialists has increased the mortality of patients suffering from various diseases. Employing technology, especially artificial intelligence technology, in medical and dental application could reduce cost, time, human expertise and medical error. This approach has the potential to revolutionise the dental public health scenario in developing countries. Clinical decision support systems (CDSS) are computer programs that are designed to provide expert support for health professionals. The applications in dental sciences vary from dental emergencies to differential diagnosis of orofacial pain, radiographic interpretations, analysis of facial growth in orthodontia to prosthetic dentistry. However, despite the recognised need for CDSS, the implementation of these systems has been limited and slow. This can be attributed to lack of formal evaluation of the systems, challenges in developing standard representations, cost and practitioner scepticism about the value and feasibility of CDSS. Increasing public awareness of safety and quality has accelerated the adoption of generic knowledge based CDSS. Information technology applications for dental practice continue to develop rapidly and will hopefully contribute to reduce the morbidity and mortality of oral and maxillofacial diseases and in turn impact patient care. ©2010 FDI/World Dental Press.
