AbstractTHE PURPOSE OF STUDY was to compare probing dept resolution achieved by gingvectomy andperiodontal flap techniques in the treatment of nifedipine-induced gingival enlargement. Tenpatients who were receiving nifedipine for at least 6 months participated in the study. Fivepatients were randomly to the ginvivectomy group and five patients to the periodontal flapgroup. Only anterior segment of the oral cavity (canine to canine) were surgical treated. Clinicalmeasurements, including probing depths, plaque index, and gingival sulcus index, were taken atbaseline, 6 weeks, 6 months, and 1 year. Result showed that probing depths were similar in sixweeks in both groups after treatment, while significant differences were found for theperiodontal flap group when compared to the gingivectomy group at 6 months (2.58 ± 0.38mmversus 4.9 ± 0.8mm, respectively) and one year (3.3 ± 0.65mm versus 6.40mm ± 1.02mm,respectively). Within its limitations, this study suggests that pocket reduction achieved by theperiodontal flap may be sustained of longer periods of the time than by the gingivectomytechniques in the treatment of nifedipine-include gingival enlargement.
Gingival Enlargement
Gingival Overgrowth = Gingival Hyperplasia or Hypertrophic
And/orInflammation Fibrotic component
Gingival enlargement results from inflammatory changes induced byDeposition of plaque and CalculousSystemic administration of certain drugs
including Phenytoin, Nifedipine, and Cyclosporine A
Inflammatory enlargement Chronic Acute
Drug-induced enlargement Enlargements associated with systemic diseases
Conditioned enlargement Pregnancy Puberty Vitamin C deficiency

Purpose The purpose of this study was to compare
probing depth resolution archived by gingivectomy and periodontal flap techniques as surgical treatment modalities for gingival enlargement associated with Nifedipine.

The prevalence of hypertension was 12 % in a rural community and 25 % in a semi-urban community ( Aged 35 to 64 years )
Among these with hypertension 28 % were Diabetes
The most commonly prescribed drugs
Thiazide diuretic Beta-blockers Angiotension-converting enzyme inhibitors Calcium Channel Blockers ( Nifedipine )
The most commonly prescribed drugs

Nifedipine is a dihydropyridine which belong to the class of pharmacological agents known as calcium antagonistCalcium Channel Blockers are drugs developed for the treatment:
Angina pectoris, unstable angina, chronic stable angina, ventricular arrhythmias, hypertension, Coronary artery spasms and Cardiac arrythmia
Calcium Channel blockers commonly used inCambodia
- Norvase (A) USA - Stamlo (A) - Adalate (N) Fr. - Loxen (Na) Fr.- Nifelat (N) - Topdip (A)- Amdocal plus (A) - Adipin (A)- Amlopres (A) - Nipine (A)- Amzel (A) - Amlopin (A)- Amark (A) - Medicolat (N)- Amlocor (A) - Nifedipine denk (N)
Materials and MethodsPatient Eight individual patients ( 6 men, 4 women) Aged 37 to 71 years All of them had a history of hypertension and
cardiovascular disorders Nifedipine 20-40 mg per day ( 6 to 38 ) months Gingival enlargement covering at least one third
of clinical crown and no evident of clinical attachment loss
Only anterior teeth has been selected ( Canine to canine ) in this study
Clinical Parameters Probing depth (PD) Clinical attachment level (CAL) Plaque index Gingival sulcus index
Surgical Treatment Gingivectomy techniqueA scalloped external bevel incision was made at
CEJ level Kirkland knife and Orban knife Following removal of the enlarged gingival
tissue, gingivoplasty was performed using a #8 round diamond bur at high speed in order to restore physiological gingival form.
Scaling and root planing was performed by hand currets and hemostasis achieved by pressure
Periodontal flap techniqueBuccal and lingual Periodontal flap were
performed from mesial line angle of the first bicuspid to the mesial line angle of the contra-lateral bicuspid
An inverse bevel incision was performed with a # 15 blade at the CEJ level
The inner surfaces of the buccal and lingual flaps were thinned with the same blade
The flaps were raised by Periosteal elevator and the collar of tissue was removed by currets and scaling and root planning performed
4-0 Vicryl suture were employed
Gingivectomy
Flap operation
Gingivectomy
Patients in both group were received periodontal dressing following surgical procedure and oral hygiene were instructed.
0.2 chlorexidine solution ( 1 minute rinses every 8 hours for 7 days )
Amoxicillin ( 500 mg every 8 hours for 7 days )Acetaminophen 500mg and Ibuprfen 400 mg( every 8 hours as needed )Post operative examinations consisting probing depth, plaque index and gingival index were performed at 6 weeks and 6 months

Discussion Gingival hyperplasia is an important side affect for
people who takes Calcium antagonists ( Nifedipline ) over than three month
After treatment, good oral hygiene in preventing severe hyperplasia was supported by our finding
Gingival enlargement is more severe in area where local irritants such as plaque, defective restoration
Some hyperplastic tissue can interfere with dental occlusion and mastication
There was no significant different of probing depth in six weeks between gingivectomy and flap operation technique
Conclusion
Long term use of Nifedipine induce Gingival Enlargment
Good oral hygiene and regular maintenance can control severe gingival hyperplasia
Pocket reduction achieved by the periodontal flap may be sustained of longer period of the time than by gingivectomy techniques in the treatment of Nifedipine - induce gingival enlargement
