Review and case report of the treatment in a young girl with primary failure of eruption.

Any localized non-eruption of teeth can be attributed to myriad of factors. A failure of a permanent tooth to erupt or cessation of initial eruption with no obvious local/systemic causative factor is said to be primary failure of eruption (PFE). The etio-pathogenesis of PFE is due to the mutation of PTH1R gene. Clinical features such as infra-occluded teeth, posterior open bite, lack of any cause or habit are usually attributed to diagnosing the condition, and a confirmatory diagnosis is done by the gene analysis of PTH1R gene. Treatment of such a condition is tricky as any application of orthodontic traction to teeth affected by PFE will not be successful and may cause ankylosis. This correspondence reviews and demonstrates the treatment of a case of PFE to restore function and esthetics to the best possible outcome.

Physiologic Midtreatment Tooth Movement as a Correction Strategy for Iatrogenic Root Exposure.

In the case report showcased, we describe orthodontic treatment of a female patient with an excessive gingival display on smiling and severe dental crowding, with maxillary canines positioned excessively buccal (ectopic) to and in near transposition to the lateral incisors. The treatment involved extractions and initial use of unmitigated forces leading to excessive gingival thinning and buccal root positioning of the ectopic canines. Eventually, the root position was corrected and periodontal equilibrium was attained. On finishing the treatment, all objectives were achieved with a good esthetic outcome as well as excellent dental and occlusal relationships.

Biomedical waste management practice in dentistry.

Biomedical Waste Management practice in Dentistry is an important issue. Therefore, it is of interest to document awareness on such issues among clinical practitioners, academicians and students. A survey was completed using a questionnaire from 355 dentists consisting of 201 students, 39 academicians and 115 clinicians in India. Analysis of the survey data shows that majority of students, practitioners, and academicians are aware of laws binding with such issues. However, the Biomedical Waste Management practice among them is not satisfactory. Therefore, education on such issues among clinical practitioners, academicians and students is critical in this part of the globe.
