RESUMEN
BACKGROUND: The mainstay of periodontal therapy is mechanical removal of subgingival plaque. There is considerable interest in supplementing it with the use of antibiotics and antiseptics. Many drawbacks are associated with these adjunctive pharmacological regimens such as development of resistance to antibiotics and disruption of microflora of the gastrointestinal tract. Hence, alternate means of killing subgingival bacteria are clearly desirable. One such method is the use of laser. AIM: This study aimed to investigate antibacterial capabilities of gallium-arsenic (Ga-As) laser on photosensitized periodontopathic organisms. The three bacteria selected for the study were Porphyromonas gingivalis, Fusobacterium nucleatum, and Prevotella intermedia. SETTINGS: The subjects for the study were selected from the patients visiting the Department of Periodontics, Karnataka Lingayat Education Society's Institute of Dental Sciences, Belgaum. DESIGN: In vitro study design. MATERIALS AND METHODS: Subgingival plaque samples collected from chronic periodontitis patients were cultured anaerobically for 72 h. Predetermined number of colonies of each bacterium was taken and was then divided into cases and control groups. Both groups were photosensitized using toluidine blue O (TBO) dye and the case groups were irradiated with Ga-As laser. Bacterial colonies were then serially diluted and were incubated for subculture. After incubation period, the number of viable bacterial count was performed. STATISTICAL ANALYSIS: Wilcoxon-signed rank test was carried out to determine significance of reduction on subsequent dilution within the bacterial group. Mann-Whitney U-test was performed to determine the significance of reduction between cases and control of particular bacterial group. RESULTS: The results revealed substantial reduction in the viable bacterial count. F. nucleatum was found to be most sensitive to killing by laser irradiation followed by P. intermedia and then P. gingivalis. Further, the TBO dye per se did not have any significant bactericidal effect. CONCLUSION: Photodynamic Therapy may prove to be a promising method for eradicating periodontopathic bacteria in near future.
RESUMEN
Coronal fractures of the anterior teeth are a common form of dental trauma. If the original tooth fragment is retained following fracture, reattachment of the fractured fragment to the remaining tooth can provide better and long lasting esthetics, improved function, a positive psychological response, and is a faster and less complicated procedure. This paper reports on coronal tooth fracture case that was successfully treated using adhesive reattachment of fractured fragment and post placement.
RESUMEN
Gingival overgrowth is well documented side effect associated with three major classes of drugs viz, anticonvulsants, calcium channel blockers, and immunosuppressants. Despite our greater understanding of pathogenesis of Drug induced Gingival Overgrowth (DIGO), its treatment still remains a challenge for the periodontists and treatment is still largely limited to maintenance of improved level of oral hygiene and surgical removal of overgrown tissue. Dental Surgeons need to discuss this issue with their medical colleagues and to practice care while prescribing the drugs associated with gingival overgrowth. The aim of present article is to report a rare case where even after extraction of all teeth; the enlargement did not subsided for one month.
RESUMEN
AIM: A cross-sectional radiographic orthopantomogram (OPG) survey was done to determine the prevalence of apical periodontitis (AP) in root canal-treated teeth in a selected population, and to evaluate the influence of the coronal restorations (CR) and root canal fillings on the periapical status. MATERIALS AND METHODS: A total of 250 OPGs were evaluated out of which root canal treatment (RCT) had been performed in 438 teeth which was taken as the sample size. STATISTICAL ANALYSIS USED: Chi-square test, odds ratio and p-values were recorded. RESULTS: The results showed that 53.1% of the endodontically treated teeth presented with AP radiographically. Incidence of AP among teeth with acceptable RCT (32.3%) was significantly lower than those suffering from unacceptable RCT (92.7%). Moreover, adequate CR demonstrated a significantly better periapical status (83.2%) compared to teeth with inadequate CR (37.2%). Also, the combination of adequate CR and adequate root filling resulted in significantly reduced incidence of AP (21.6%) compared to the presence of AP (97%) when both parameters scored as inadequate. CONCLUSION: RESULTS hence demonstrated that a well-performed RCT and well-sealing CR are both essential for the overall success of endodontic treatment. Therefore, a considerable improvement in the quality of RCT and CR in general dental practice is required to promote oral/periapical health.
