Non-syndromic generalised hypotaurodontism in a case of Stage III Grade C periodontitis.

Taurodontism is a rare dental morphological anomaly characterised by an unusual increase in the vertical height of the pulpal chamber along with an apical displacement of the pulpal floor. The tooth lack constriction at the cementoenamel junction is mimicking a bull tooth. Taurodontism is usually observed as an isolated tooth aberration. However, it can also be associated with specific syndromes such as Down's syndrome, amelogenesis imperfecta, Klinefelter syndrome, Tricho-Dento-Osseous syndrome, Mohr syndrome, Prader-Labhart-Willi syndrome, Ellis van Creveld syndrome and Lowe syndrome. Periodontitis is characterised by microbially associated, host-mediated inflammation that results in loss of periodontal attachment. This case report describes a rare case of non-syndromic generalised taurodontism in a male patient with Stage III Grade C periodontitis. The patient was promptly given periodontal care by root planing and Kirkland flap surgery.

Comparative Analysis of Electric Field Strength, Magnetic Field Strength and Power Density around the Cell Phone Towers of Varying Characteristics with a Proposed Classification Facilitating Research on Human Population.

The continuous exposure of electromagnetic field (EMF) radiation from cell phone towers may possibly have an influence on public health. Each cell phone tower is unique in terms of number of antennas and its associated attributes; thus, the radiation exposure varies from one tower to another. Hence, a standardized method for quantifying the exposure is beneficial while studying the effects of radiation on the human population residing around the cell phone towers. A mere collection of data or human samples without understanding the cell phone tower differences may show study results such as an increase or decrease in biological parameters. Those changes may not be due to the effects of EMF radiation from cell phone towers but could be due to any other cause. Therefore, a comparative study was designed with the aim of quantifying and comparing the electric field strength (EF), magnetic field strength (MF) and power density (PD) on four sides of cell phone towers with varying numbers of antennas at 50 m and 100 m. Further, an attempt was made to develop a PD-based classification for facilitating research involving human biological samples. Through convenience sampling, sixteen cell phone towers were selected. With the use of coordinates, the geographic mapping of selected towers was performed to measure the distance between the towers. Based on the number of antennas, the cell phone towers were categorized into four groups which are described as group I with 1-5 antennas, group II comprising of 6-10 antennas, group III consisting of 11-15 antennas and group IV comprised of towers clustered with more than 15 antennas. The study parameters, namely the EF, MF and PD, were recorded on all four sides of the cell phone towers at 50 m and 100 m. One-way ANOVA was performed to compare the study parameters among study groups and different sides using the Statistical Package for the Social Sciences (SPSS) version 25.0. The mean MF in Group IV was 2221.288 ± 884.885 µA/m and 1616.913 ± 745.039 µA/m at 50 m and 100 m respectively. The mean PD in Group IV at 50 m was 0.129 ± 0.094 µW/cm2 and 0.072 ± 0.061 µW/cm2 at 100 m. There was a statistically significant (p < 0.05) increase in the MF and PD at 50 m compared to 100 m among cell phone tower clusters with more than 15 antennas (Group IV). On the other hand, a non-significant increase in EF was observed at 50 m compared to 100 m in Group II and IV. The EF, MF and PD on all four sides around cell phone towers are not consistent with distance at 50 m and 100 m due to variation in the number of antennas. Accordingly, a PD-based classification was developed as low, medium and high for conducting research involving any biological sample based on quantile. The low PD corresponds to 0.001-0.029, medium to 0.03-0.099 and high to 0.1-0.355 (µW/cm2). The PD-based classification is a preferred method over the sole criteria of distance for conducting human research as it measures the true effects of EMF radiation from the cell phone towers.

Sharp tooth induced sublingual hematoma in a patient with elevated international normalized ratio.

Sublingual hematoma secondary to anticoagulation is a rare fatal condition. Hemorrhagic complications of warfarin are well-known. This particular case is unique because the patient was on warfarin for the past 2 years but did not develop the sublingual hematoma. However, a trauma by an attrited sharp cusp triggered the episode of the sublingual hematoma in this patient. Being a medical emergency, patient was promptly hospitalized in cardiac care unit and managed by medical team. The patient was transfused with 2 units of fresh frozen plasma and warfarin was temporarily stopped for 4 days. Alternate day regimen of warfarin was started after 4 days, and international normalized ratio dropped to 3. In dental management, enameloplasty of the mandibular first molar tooth was done to prevent trauma and ulcer development in the floor of the mouth. The hematoma resolved, and no new hematoma formation was observed for a period of 6 months.

Double frenum weds fusion: a rare wedlock?

Morphological variation of normal oral structures such as double frenum and fusion together in a patient is rare. Sometimes such scenarios may mislead the diagnosis, affecting treatment planning and prognosis. Hence a thorough evaluation of patients with such morphological defects is necessary. This case report describes a case of double frenum and fusion, and the multiple challenges the clinician faces.
