A case report of sequestra formation in the oral cavity most probably as a sequelae of periodontal abscess in a diabetic patient is presented. The sequestra probably formed as a complication of uncontrolled diabetes mellitus rather than erythroleukemia. The lesion was located at the bifurcation area of the lower left second molar. Removal of the sequestra, scaling and a course of antibiotics managed to control the lesion.
An important relationship should exist between the periodontist and restorative dentist. Periodontics and restorative dentistry should not be divisible and all forms of restorations, from a simple filling to a complex precision-retained bridge, should be performed with the health and biology of the periodontium in mind. A very crucial concept which should be borne in the mind of every restorative dentist is the concept of biologic width.
This study evaluated the effect of a Probiotic mouthrinse containing nisin, a bacteriocin extracted from Lactococcus lactis on dental plaque and gingivitis in young adult population. A group of 32 subjects were randomly assigned into two groups of 16 each. The first group started using the control mouthrinse (placebo) for 2 weeks followed by a washout period of 4 weeks. This group then used the test mouthrinse (Probiotic) for a further duration of 2 weeks. The second group followed a similar protocol as the first except that this group started with the test mouthrinse (Probiotic). Plaque Index (PI) and Gingival Index (GI) were recorded at baseline and after 2 weeks for each group. All subjects were given full mouth prophylaxis after each measurements. The results of this study showed that rinsing with Probiotic mouthrinse resulted in a statistically significant reduction of plaque accumulation and gingivitis compared to rinsing with placebo. The results indicated that Probiotic mouthrinse containing nisin had the potential of inhibiting plaque accumulation and was effective in reducing gingivitis.
Severe gingival recession caused by dehiscence usually present a challenging task to the clinician as any mucogingival surgery without bony regeneration will not 'prevent the condition from recurring. The procedures of guided tissue regeneration ( GTR ) which allow regeneration of the lost periodontium may offer some solution to the condition. This paper reports on the use of a non-resorbable GTR membrane to treat an isolated lower incisor gingival recession associated with dehiscence.
Gingival overgrowth is frequently observed in patients taking certain drugs such as calcium channel blockers, anticonvulsants and immunosuppressant. This can have a significant effect on the quality of life as well as increasing the oral bacterial load by generating plaque retention sites. Amlodipine, a third generation calcium channel blockers has been shown to promote gingival overgrowth although in very limited cases reported. The management of gingival overgrowth seems to be directed at controlling gingival inflammation through a good oral hygiene regimen. However in severe cases, surgical excision is the most preferred method of treatment, followed by rigorous oral hygiene procedures. This case report describes the management of gingival overgrowth in a hypertensive patient taking amlodipine. Combination of surgical gingivectomy and CO2 laser treatment was used to remove the gingival overgrowth. CO2 laser surgery produced good hemostasis and less pain during the procedure and post operatively. This case report has also shown that periodontal treatment alone without a change in associated drug can yield satisfactory clinical response.
The aim of this study was to determine the effectiveness of demineralized freeze-dried bone xenograft (DFDBBX) in minimizing post-surgical recession in moderate to advanced adult periodontitis in patients. Nine patients with a total of eighteen intrabony defects were matched for the tooth type, location of defects and periodontal pocket depth (5 to 7mm). Following an initial nonsurgical treatment, recession at defects indicated for surgery was measured pre-operatively. Surgical treatment was carried out by split mouth design, where the test sites were assigned DFDBBX and the control sites were subjected to debridement without the use of DFDBBX. Recessions were measured at 3 months, 6 months and 9 months post-operatively. The results showed no statistically significant difference in mean recession at 3, 6 and 9 months post-operatively compared to baseline for both test and control groups. Thus, DFDBBX was ineffective in minimizing recession on patients with moderate to severe periodontitis, as compared to surgical debridement alone.
This study evaluated the effectiveness of demineralized freeze-dried bone xenograft in reducing post-surgical pocket depth in moderate to advanced adult periodontitis in patients. Nine patients with a total of eighteen intrabony defects were selected for this study. The bony defects were matched for tooth type, location and pocket depth. Following an initial non-surgical treatment, only pockets of 5 to 7 mm deep were indicated for surgery. Periodontal pockets were measured pre-operatively and at 3, 6 and 9 months post-surgically. The study protocol included a split mouth design, where surgical treatment was carried out at both test and control sites. The test sites were assigned demineralized freeze-dried bone xenograft and the control sites were subjected to debridement alone without the use of demineralized freeze-dried bone xenograft. The results from this study showed a statistically significant difference in the mean pocket depth at 6 and 9 months post-operatively for both test and control groups, but there was no statistically significant difference at 3 months. In conclusion, demineralized freeze-dried bone xenograft was ineffective in reducing periodontal pocket depth in patients with moderate to severe periodontitis, as compared to surgical debridement alone.
