Can buccal infiltration of articaine replace traditional inferior alveolar nerve block for the treatment of mandibular molars in pediatric patients?:…

2021

Background It is unclear if buccal articaine infiltration can be used as an alternative to standard inferior alveolar nerve block (IANB) for treating mandibular molars in pediatric patients. Therefore, this study aimed to pool evidence to compare the efficacy of buccal infiltration of articaine vs IANB with lignocaine for pediatric dental procedures. Material and Methods We searched the PubMed, Embase, ScienceDirect, CENTRAL, and Google Scholar databases for randomized controlled trials (RCTs) comparing the two techniques in pediatric patients and reporting the success of anesthesia and/or pain during treatment. PRISMA guidelines were followed. Results Seven RCTs were included. Pooled analy…

Cranial circulation of the pen-tailed tree shrewPtilocercus lowii and relationships of Scandentia

1994

The major cranial arteries and veins are described for a 30-mm crown-rump length fetus of the pen-tailed tree shrewPtilocercus lowii, and comparisons are made with cranial vessels reported in the tree shrewTupaia and with the vascular pattern reconstructed for primitive eutherians.Ptilocercus shares a number of derived features of the cranial circulation withTupaia, which, therefore, represent synapomorphies of tree shrews (Tupaiidae, Scandentia). Included are (1) the enclosure of the intratympanic portion of the internal carotid artery in a bony canal that is floored proximally and distally by the entotympanic and by the petrosal in between, (2) the enclosure of the intratympanic portion o…

Mucormycosis infection associated with global COVID-19 pandemic - an institutional histopathological study

2023

Coronavirus disease 2019 (COVID-19) in the recent times have instilled signs of immunosuppression globally which has further precipitated increasing range of opportunistic infections. Mucormycosis is a distressing opportunistic fungal infection with a high incidence and is the third commonest acute invasive infection following candidiasis and aspergillosis. The aim of the present observational study is to delineate the enigmatic histopathological profile between mucormycosis cases seen prior to pandemic (PPM) and pandemic associated mucormycosis (PAM). Tissue archives of 105 histopathologically diagnosed cases of mucormycosis were included and analysed for demographical details and histopat…

Juvenile central ossifying fibroma of the mandible: a case report

2010

Central ossifying fibroma is a rare fibro-osseous neoplasm in young children. It is highly aggressive and has a strong tendency to recur. We describe an 11-year-old girl with juvenile central ossifying fibromas of the mandible that caused obstruction of tooth eruption of the lower left second premolar. Oral examination revealed the presence of the primary lower left second molar and a small bony hard swelling over the left side of the mandibular body. After a computed tomographic scan, an incisional biopsy was performed, and the lesion proved to be a juvenile ossifying fibroma. Although this tumor often recurs early, and many authors suggest radical en bloc resection, we performed a more co…

Hypovitaminosis D, oral potentially malignant disorders, and oral squamous cell carcinoma: a systematic review

2021

Oral squamous cell carcinoma (OSCC) and potentially malignant oral disorders (OPMDs) could be associated with low levels of vitamin D. This systematic review aimed to determine the relationship between serum levels of vitamin D with OPMDs and OSCC. This review was conducted according to Cochrane guidelines (PROSPERO CRD42020207382) on literature retrieved from the PubMed, Cochrane, and Web of Science databases. The antecedents extracted were study design, methodology, sample (country, number of patients, age, and sex), oral manifestations (type of lesion, location, prevalence, and follow-up), serum vitamin D levels or use of vitamin D supplements, results, and conclusions. Twelve articles w…
