Calculus consists of mineralised dental biofilm on the surfaces of teeth and dental prosthesis, the location of which can be detected by using a periodontal or an electronic probe. Detection of subgingival calculus is critical for successful treatment outcome in the management of periodontal patients. The aim of this study was to detect subgingival calculus using manual and electronic probe and to compare the reliability and the accuracy of both methods. The study was carried out in vitro on thirty-two extracted teeth with calculus mounted in frasaco model. A total of 192 sites on six surfaces of the teeth bucally and lingually were recorded for the presence of subgingival calculus. Manual probing of calculus depended on tactile sensation and experience; where as electronic probing gave sound and light signal. The results showed that at the depth of 1-3 mm, manual probing could detect 62.7% of calculus and electronic probing could detect more at 77.1%. At the deeper sites of 4-6mm, the ability for detection using electronic probing reduced to 14.1% with failure for detection at ≥ 7mm depth. However manual probing recorded more at 25% for 4-6 mm calculus and 4.7% at ≥7mm. Manual and electronic probing has different sensitivity in detecting subgingival calculus with electronic probing being more sensitive at shallow sites and failed to detect calculus at deeper sites. It also has difficulty to differentiate between calculus and other roughness on tooth surfaces. These findings highlighted the accuracy and reliability of manual detection for deeper calculus. Redesigning calibration and length of electronic probe can improve its usage. Further study on clinical application to assess the impact of both probing may benefit clinical teaching of subgingival calculus detection and the outcome of periodontal patient’s management.

In the management of periodontitis patients, periodontal risk assessment (PRA) tool is currently being applied during periodontal review (PR). However, an assessment of risk profiles during examination and diagnosis (E&D) may and would effectively assess and diagnose patients’ periodontal conditions, provide personalised treatment planning, and render an enhanced patient care through periodontal management by risk assessment (PEMBRA). From a retrospective study on selected records of 81 patients treated for chronic periodontitis, the PRA profiles of the patients were evaluated during E&D and two to three months after completion of nonsurgical periodontal therapy (NSPT) during PR. The results were analysed using SPSS version 24 for descriptive statistics. On E&D, the patients presented with 25.9% localised and 74.1% generalised chronic periodontitis. Of these, 2.5% of low-risk patients on E&D increased to 21% during PR signifying an improvement after the treatment. However, the medium-risk patients have a slight increase from 32% to 35%, and patients with a high risk of 62% were reduced to 43%. The improvement of the risk profiles for both low and high-risk groups was mostly contributed by the reduction in the plaque score, percentages of bleeding on probing (BOP), and probing pocket depth (PPD) ≥ 5 mm. This evidence-based evaluation of PRA tool during E&D and PR is important for PEMBRA as it encouraged the clinicians to adopt periodontal management through basic periodontal examination, detailed periodontal charting, radiographic interpretation, tooth per tooth prognosis, diagnosis, and targeted NSPT.

The use of corrective force against the wife is still rife in all cultures and even socially acceptable in some culture. Domestic violence is still common in our society. We report a case of 20 years old woman who admitted into OCC of DMCH through emergency department owing to be assaulted by her husband. This case is exceptional one because the injuries inflicted upon her were over the middle of the forehead and clean cut in nature, though non fatal. Awareness and education is needed to stop this social stigma DOI: http://dx.doi.org/10.3329/bjms.v11i3.11736 Bangladesh Journal of Medical Science Vol. 11 No. 03 July’12
