The ultimate goal of tissue engineering is to reproduce functional alveolar∖Periodontal complex. This study aimed to asses micro- and nano-formulated crystalline calcium sulfate as possible treatment of intrabony defect utilizing an autologous Platelet rich fibrin scaffold.
and Methods An experimental prospective split mouth design using eight healthy mongrel dog's was conducted. After two months of extracting the first premolar, bilateral intrabony defects were created mesial to the mandibular second premolar. One side was grafted by nanocrystalline calcium sulfate, while, the opposite side was grafted with microcrystalline calcium sulfate graft. Dogs were randomly euthanized after one month (group I) and 3 months (group II). The primary outcomes were the histological changes of new bone formation in hematoxylin and eosin and Masson trichrome stains, while histomorphometric and radiographic analysis were the secondary outcome followed by statistical analysis (P value was set at .05).
There was a significant increase in the percentage of bone formation in relation to defect height in nanocrystalline compared to microcrystalline form after one month and three months in both histological (p-values of <0.0001) and radiographic results (p-values of <0.0001).
Nanocrystalline calcium sulfate presented a significant enhanced periodontal regeneration compared to the microcrystalline form.

To assess the correlation between the diameter of the mandibular lingual vascular canal (MLVC) as determined on CBCT examination to blood flow and arterial diameter as determined by ultrasound Doppler analysis (USG) in dentate and edentulous patients.
20 subjects were equally distributed into two groups based on the status of their dentition. Group 1 included dentate subjects (DE) and Group 2 included edentulous subjects (ED).The subjects from both the groups underwent CBCT scan for the assesement of the diameter of the MLVC.Similarly, USG was done to assess the diameter of the sublingual artery anastomosis and blood flow in the anterior mandible. Data was analysed using Karl Pearson's Correlation coefficient test and Student's unpaired 't' test.
Irrespective of the status of the dentition and age, a positive correlation was noted between the diameter of foramen on CBCT examination and the diameter of anastomosing artery as studied by the USG (r=0.290).Similarly, a positive correlation was observed between the diameter of foramen on CBCT and the volume of blood entering the mandible (r=0.447).A positive correlation (r=0.138) was observed between the diameter of the anastomosing artery and the volume of blood entering the mandible.
The anterior mandible has a rich vascular supply independent of age and status of the dentition.The dimensions and location of MVLC could be assessed on a CBCT prior to implant placement so that the operating surgeon has an idea about the vascularity of the region. Further studies with higher sample size should be undertaken to confirm these findings.

Oral squamous cell carcinoma (OSCC) still lacks the valid prognosticator for survival. Tumor associated tissue eosinophilia (TATE) have been widely investigated in the literature but still there is no consensus viewpoint on its role as prognostic marker. With this view in mind, a systematic review and meta-analysis of studies that evaluated the overall risk of elevated TATE and survival in OSCC was conducted
A systematic literature search conducted to identify studies that have evaluated TATE in OSCC. Overall survival (OS), Disease Free Survival (DFS) Hazard ratio (HR) with 95% confidence interval) was extracted. HR was extrapolated if direct HR was not given in publication. Studies were pooled and combined hazard ratios (HRs) of High TATE for OS and DFS were calculated.
6 out of 874 articles were found eligible for systematic review and meta-analysis. High TATE was predictor of OS (
HR 0.45 (95% CI, 030-0.65,
<0.0001)) and DFS (
HR 2.33 (95% CI, 0.74-7.37)) in OSCC patients.
High TATE positively predicts OS and DFS in OSCC and thus can be regarded as an important survival prognosticator. Standardization of counting and reporting methodology for TATE count is recommended on future cohort studies.

To assess the effectiveness of mobile phone applications in improving oral hygiene care and oral health outcomes in patients undergoing fixed orthodontic treatment.
PUBMED/MEDLINE, CINAHL, EMBASE, COCHRANE, PROQUEST, Google Scholar, and Web of Science were systematically searched for original studies published between January 2000 and March 2020. The eligibility criteria being (i) observational study [cross-sectional, case-control, cohort study, or RCTs] that reported mobile phone application as an intervention or exposure for oral hygiene care. Standard Protocol Items Recommendations for Interventional Trials (SPIRIT) statement was used for quality assessment of interventional studies. The comprehensive search strategy yielded 154 studies after the removal of duplicates. Based on eligibility criteria only 5 studies were included in the data extraction phase.
This review finds that smartphone applications have a significant short term effect in the improvement of oral hygiene when measured using plaque index and gingival index scores. The mean plaque index and gingival index reduced significantly in three out of five studies. The intervention groups [62%] had a lower level of plaque at a 12-week interval as compared to the control group [72%]. Short term follow-ups showed greater improvement in oral hygiene following smartphone application administration.
Within the available evidence, a recommendation can be made for the use of mobile applications in the orthodontic process [oral hygiene] care.
Further research for the development of patient-centered applications for patient safety, clinical decision making, and increasing their effectiveness in the treatment of orthodontic patients are required.

Literature search shows scarcity of information regarding the use of Dental Operating Microscope (DOM) in children. There are various factors that limit the use of this novel technology by Pediatric Dentists in their practice. PYR-41 The aim of this study is to assess the knowledge, attitude and practice of pediatric dentist regarding DOM use in children.
The present study was a descriptive web based questionnaire study conducted among 363 Pediatric Dentists (PDs) of India. A close-ended questionnaire was prepared to test the KAP regarding microscope use among PDs. Results obtained were analyzed using descriptive analysis in SPSS software and correlation was studied using chi-square test where statistical significance was observed at p<0.05.
A response rate of 82.1% was observed. Majority (88.9%) of the pediatric dentists were aware of Dental operating Microscope (DOM) usage in their field, however, only 61.4% were aware of its magnification levels. 76.5% participants responded 12
clock position to be the ideal position. Majority (94.0%) agreed that DOM is helpful in locating canals in deciduous teeth. 70.5% think that DOM can increase apprehension of children. 85.2% believed that DOM can aid in behavior management of children through its live visual output. However, 84.2% of the pediatric dentists hadn't used DOM in their practice.
The knowledge, attitude and practice regarding dental operating microscope among pediatric dentists in India is limited. In the foreseeable future, the use of magnification is likely to become the standard of practice in dentistry.

A complete bilateral maxillectomy defect presents a considerably reconstructive challenge for the prosthodontist because of the absence of normal hard and soft tissues for the support of prosthesis. The surgical obturator was retained via spring which develops the seal between the acrylic plate and the dorsum of the tongue during deglutition, thus helping the patient to take a soft diet orally during the healing period. The definitive conventional closed bulb hollow obturator fabricated using the "lost wax bolus" technique, is a reliable and feasible treatment option to restore the total maxillectomy defect, thus improving and enhancing the quality of patient's life and livelihood.Dandy-Walker (DW) complex is a rare central nervous system malformation, commonly associated with complex non-neurological conditions, defined by four variants with characteristic anatomic features, still inadequately known for its etiological aspects. "Mega Cisterna Magna" (MCM) is a type of DW complex which is represented by an enlarged posterior cranial fossa. Though reduction cranioplasty has been reported in enlarged posterior cranial fossa malformations, however we report a peculiar case of MCM with massive posterior cranial bone erosion, presenting completely asymptomatic at an age of 8 years, without any associated co-morbidities till date, nor with any evident occipital mass at birth. Survival of the child till this age is an exception in itself, but this can probably be explained by the presence of the giant defect of the posterior cranial bone, which must have acted like a vent and prevented the elevation of the ICP. Hence no symptoms were observed till date. Ventriculo-peritoneal (VP) shunting was done to drain the accumulated fluid, followed by massive cranioplasty, which was challenging and was performed with autologous cranial and fibular bone grafts, along with alloplastic titanium mesh, and thus achieving marked aesthetic improvement with satisfactory bone healing at a 3-year follow-up.The panoramic radiographs for localisation of impacted canines are now mostly available in the digital form. It is difficult to apply the localisation techniques in the digital format especially when it is viewed and diagnosed using smart phones. So in this paper we are describing about an app we created based on the android platform. Using this app three localisation methods can be applied by using multiple tools.
