Objective: this study was carried out to evaluate the relationship between smoking and periodontal status in a selected Malaysian population. The sample for this cross-sectional study involved 39 subjects who were smokers. Each subject was required to answer the guided questionnaire followed by clinical examination. The questionnaires had 11 questions and were set in English and Bahasa Melayu. Basically, the questionnaire consisted of 3 sections: socio-demographic data, smoking status and subject's knowledge on periodontal health. The clinical parameters used in this study were: Community Periodontal Index, Visible Plaque score, Gingival Bleeding Index and Calculus Surface Index. Results showed that out of 39 subjects, 28 subjects (71.8%) were current smokers, followed by 6 subjects (15.4%) and 5 subjects (12.8%) who were former and who never smoked respectively. From the 216 sextants examined, 42 sextants (19.4%) were healthy gingival, 127 sextants (58.8%) suffered from gingivitis and 47 (21.8%) sextants suffered from periodontitis. There were positive relationships between smoking and periodontal status.
The objectives of this study were to measure the Furcation Entrance Dimensions of first and second permanent molars in Malaysian samples and to compare the Furcation Entrance Dimensions with the blade widths of periodontal Gracey’s curette used for root surface instrumentation. A total of 199 extracted permanent teeth were measured, which comprised of 51 mandibular first molars, 51 mandibular second molars, 45 maxillary first molars and 52 maxillary second molars. Furcation Entrance Dimension was measured using calibrated test gauges. Results showed 51.91% of Furcation Entrance Dimension was
Objective: This retrospective study aims to evaluate the possible effects of antihypertensive drugs on alveolar bone loss in patients with chronic periodontitis. Methods: 50 patients on antihypertensive drugs selected as the experimental group and 50 patients with chronic periodontitis with no known systemic illnesses as control group were randomly selected as the study samples. Orthopantomographs were obtained, calibration and assessment of alveolar bone loss was performed by using the computer software program available in the faculty, through radiographic linear measurement procedure. Premolars, first and second molars of both maxilla and mandible were measured from the most apical point to the cementoenamel junction for mesial and distal aspects in the form of millimetres and percentile of the root length. Data was statistically analyzed using independent t-test and Analysis of Covariance in SPSS Version 23 with significance at P-value, p
A study was undertaken to estimate the histological changes of gingival enlargement induced by
Cyclosporin A (CsA) and Nifedipine, separately and in combination. Twelve adult rabbits were divided equally into four main groups. The first group received 10 mg/kg/day Nifedipine, the second received 10 mg/kg/day CsA, and the third received a combination of 10 mg/kg /day Nifedipine and CsA by gastric feeding. The fourth was regarded as a control group. Animals were given the drugs from day 1 of the experiment until day 70. They were then sacrificed for histological purposes. Results showed increase in the thickness of the epithelium with keratosis and acanthosis, and also increased vascularity. Collagen fibres and fibroblasts at different rates in the three histological groups were observed. Significant alveolar bone resorption with increased marrow spaces filled with fatty tissue were found in the CsA group. Non-significant changes in the alveolar bone of the Nifedipine group while subsequent bone resorption and bone deposition were seen in the combination group. These changes could be due to the effect of both drugs. Significant changes in the gingiva and the alveolar bone were shown in the three experimental groups compared with the control group.
