Professional prophylaxis and its effect on the periodontium of full-banded orthodontic patients.

The effect of professional prophylaxis on the periodontium was studied in 14 adolescent orthodontic patients while under active treatment using a split-mouth experimental design. A full-banded appliance was used on all of the patients. The following variables were examined: plaque registration, gingival index, gingival migration, and width of the attached gingiva. Professional rubber-cup prophylaxis was performed on the test side of all patients together with reinforced oral hygiene instruction on a monthly basis. Measurements for the plaque registration, gingival index, gingival migration, and the width of the attached gingiva were recorded at the initial visit (baseline records), the 6-month evaluation, and the 10-month evaluation. Monthly registrations were completed for the plaque deposits and gingival inflammation at each of the 11 visits. All measurements were taken at the midfacial surface of the selected teeth. Four conclusions can be drawn from the findings of this study: the presence of an orthodontic appliance did not result in an increase of plaque accumulation or gingival inflammation for the full-banded orthodontic patient; monthly oral hygiene instruction was effective in significantly reducing the amount of visible plaque and gingival inflammation; monthly rubber-cup prophylaxis had a significant effect in reducing the gingival enlargement routinely associated with a fixed orthodontic appliance; and the width of attached gingiva showed no significant change throughout the course of the study.

Effects of orthodontic attachments on the gingival health of permanent second molars.

The aim of this study was to evaluate the effect of cemented bands and enamel bonded attachments on the gingival health of second molars. In 23 patients the right upper and lower second molars were banded, while the left upper and lower second molars were bonded. The plaque index, the gingival index, and pocket depths were greater and statistically significant on the right side, indicative of increased inflammatory activity where bands were cemented. Once the appliances were removed, both areas returned to pretreatment levels.

Leiomyomatous hamartoma presenting as a congenital epulis.

An otherwise-healthy 11-month-old white girl presented with a polyp-like lesion on the anteromedial part of the maxillary alveolar ridge. It looked like a congenital epulis, but histological examination showed fascicles of smooth muscle cells dispersed in collagenous stroma with a few peripheral nerve bundles that were intermingled with smooth muscle fibres. The muscle cells stained strongly for desmin and alpha-smooth-muscle actin. However, S-100 was found only in peripheral nerve bundles. It was therefore a leiomyomatous hamartoma.

Reactive hyperplasia of the oral cavity in Kerman province, Iran: a review of 172 cases.

The purpose of this study was to present the clinical features of reactive hyperplasia among Iranian people. A series of 172 consecutive confirmed cases were studied using the database available at the Department of Oral Medicine, Kerman School of Dentistry. Reactive hyperplasia was classified into five groups: traumatic fibroma, peripheral fibroma with calcification, pyogenic granuloma, peripheral giant cell granuloma, and hyperplasia caused by dentures. Age, sex, site, clinical and radiographic findings, and outcome of treatment were recorded. Ages ranged from 5 to 79 years (mean 36). More women were affected than men (M/F 1:1.5). Pyogenic granuloma (M/F 1:2.2, chi(2)=6.4, p=0.011) and hyperplasia caused by dentures (M/F 1:3.7, chi(2)=10.9, p=0.001) were significantly more common among women. Peripheral giant cell granuloma was more common among men (M/F 1.4:1). Of the 172 cases, 111 (64%) involved the gingiva. Pyogenic granuloma more often affected the maxillary gingiva, while traumatic fibroma, peripheral fibroma with calcification, and peripheral giant cell granuloma, were more common in the mandibular gingiva. Twenty peripheral giant cell granulomas and 23 pyogenic granulomas had ulcers on the surface. A tendency to bleed was common among patients with pyogenic granuloma (n=31) and peripheral fibroma with calcification (n=12). We have confirmed that the clinical features of reactive hyperplasia among Iranians are, for the most part, similar to those reported by other investigators.

Clinical investigation of amelanotic malignant melanoma in the oral region.

PURPOSE: Amelanotic oral malignant melanoma (AOMM) is a rare tumor that is difficult to diagnose. We studied the clinical and pathologic features of nine cases of this tumor to define diagnostic criteria and estimate prognoses for 2 different types of AOMM. PATIENTS AND METHODS: Nine patients with 2 different types of primary AOMM were examined between 1970 and 2002. The histopathology of surgical specimens was studied, uncertain diagnoses were supported by immunohistochemical reactions, and electron microscopy and prognoses were reviewed retrospectively. RESULTS: AOMM without radial growth phase may be particularly difficult to diagnose correctly without immunohistochemical assistance. Tumors consisted of a mixture of polygonal and spindle cells in different ratios in tumors with and without radial growth phase. The life span ranged from 3 months to 6 years 3 months, and all 9 patients died of the tumor. In 7 of the 9 cases, distant metastases were found. CONCLUSIONS: AOMM without radial growth phase may be misdiagnosed as epulis or squamous cell carcinoma. Questionable lesions, particularly maxillary and palatal lesions, must be biopsied for histopathologic and possibly immunohistochemical examinations followed by rapid treatment. The prognosis of AOMM was poor.

External cervical root resorption involving multiple maxillary teeth in a patient with hereditary hemorrhagic telangiectasia.

Hereditary hemorrhagic telangiectasia (HHT) is an inherited syndrome characterized by mucocutaneous telangiectases that commonly involve the tongue, lips, fingers, and conjunctiva. While root resorption has been reported in association with central hemangiomas of bone, the association of HHT with external cervical root resorption has not been described to date. We report a case of a 57-year-old female with HTT who presented with advanced cervical root resorption involving multiple maxillary anterior teeth. Histologic examination of the gingival tissue adjacent to the area of root resorption demonstrated multiple thin-walled vascular elements as well as larger vascular channels surrounded by a thickened muscular layer. We hypothesize that the external root resorption seen in this case is the result of the HHT-related vascular process in the adjacent gingival tissue.

Clinical assessment of injuries in orthodontic movement of impacted teeth. II. Surgical recommendations.

Adverse effects on periodontal tissues have been associated with surgical techniques used to expose impacted teeth that are to undergo orthodontic tooth movement. The purpose of this study was to compare the effects on the periodontium of two of the more commonly used surgical techniques for labially impacted canines--(1) exposure of the entire labial aspect of the anatomic crown with total excision of all keratinized tissue (the window approach) and (2) a technique which exposes only 4 to 5 mm of the most superficial portion of the labial aspect of the cusp tip while maintaining 2 to 3 mm of keratinized tissue. Twelve patients were selected who had undergone comprehensive orthodontic therapy for a unilateral labial impaction of an upper canine, and who had the impacted canine surgically exposed with a window approach. This group's periodontal status after orthodontic therapy was compared to that of another group of twelve patients who had also undergone comprehensive orthodontic therapy for a unilaterally impacted labial upper canine but in whom the surgical exposure of the impacted tooth had been performed in a manner which preserved 2 to 3 mm of keratinized tissue on the labial aspect. The results indicated that the twelve subjects in whom the window approach had been used had statistically more gingival recession, gingival inflammation, and loss of attachment on the labial and labioproximal surfaces of the impacted teeth than the other group that had 2 to 3 mm keratinized tissue maintained after surgical exposure (p less than 0.05).

A retrospective study of 236 patients with teeth restored by carbon fiber-reinforced epoxy resin posts.

STATEMENT OF PROBLEM: The Composipost dowel is made of stretched, aligned carbon fibres embedded in an epoxy-resin matrix. It is widely used in Europe and Canada for the restoration of endodontically treated teeth and was introduced in the United States 2 years ago as the C-Post dowel. PURPOSE: This retrospective study evaluated treatment outcome of the Composipost system after 2 to 3 years. MATERIAL AND METHODS: A total of 236 patients treated during a 1-year period by seven Swedish dental practitioners were included. Of those, 146 patients consented and data were collected from the dental records of the remaining patients. Thus, the material comprised 236 teeth restored with carbon fiber-reinforced epoxy resin post, 130 maxillary and 106 mandibular teeth, with a mean restoration time of 32 months (range 27 to 41). Periodontal conditions, radiographic signs, and prosthodontic results were recorded. RESULTS: Five teeth (2%) had been extracted for reasons unrelated to the Composipost system. Periodontal conditions such as plaque accumulation, gingival health, bleeding on probing, and pocket depth around the teeth with Composipost dowels were similar to the control teeth. No dislodgment or root or post fractures were observed clinically or on radiographs. Radiographic examination of bone height measured from the apex to the bone margin mesially and distally showed differences on the mesial side but not on the distal surface (p < 0.05) between the Composipost-treated teeth and the controls. CONCLUSIONS: Promising results after 2 to 3 years of clinical service indicate that this system can be a viable alternative to conventional post-and-core systems.

The fixed mandibular implant: a 6-year review.

In a review of 102 consecutive cases of the fixed mandibular implant there were no failures; all appeared clinically to be osseointegrated and functioning well. There were an unexpected number of gingival infections and instances of inflammatory gingival hyperplasia, but these have been reversible and manageable. A change in sleeve nut design has improved gingival health. The Fixed Mandibular Implant (Hall Reconstructive Systems, Carpinteria, CA) offers immediate denture stability and function, and provides the opportunity for a fixed, fixed removable, or overdenture prosthetic reconstruction.

Periodontal implications of bonded versus removable retainers.

Removable retainers have been used by clinicians since the early years of orthodontic practice. During the last decades, an increasing number of cases are retained with bonded lingual retainers. The current study was performed to evaluate whether significant differences in gingival conditions exist between patients who wear removable or fixed retainers. Differences in build-up of plaque and calculus were also investigated. Maxillary and mandibular measurements were taken at baseline (just before debonding) and 1, 3, and 6 months later, from canine to canine on 36 patients. Among these patients, 22 had fixed retainers, and 14 wore removable retainers. The gingival condition was scored according to three parameters: Modified Gingival Index, bleeding on probing, and gingival crevicular fluid flow. After staining with Diaplac, the Plaque Index was registered. The amount of calculus was measured with a calibrated periodontal probe. Gingival inflammation decreased from baseline throughout the entire period of retention. A comparable limited gingival inflammation was found in the presence of both types of retainers. Slightly more plaque and calculus were present on the lingual surfaces in the fixed retainer group. This did not result in more pronounced gingival inflammation than in the removable retainer group, within the evaluated period.

Posttreatment assessment of surgically exposed and orthodontically aligned impacted maxillary canines.

The records of 96 consecutively treated patients, with a total of 110 exposed maxillary canines, were reviewed after orthodontic alignment of the exposed teeth. In view of the high degree of clinical and patient satisfaction with the results, a random sample of 25 patients, with a total of 30 exposed canines, were critically assessed. The assessment involved scoring for clinical impression, mobility, gingival condition and pocketing, oral hygiene, vitality, and radiographic appearances. The results indicate that the technique of surgical exposure and orthodontic alignment of ectopic maxillary canines provides a satisfactory method of treatment.

Mucogingival considerations in orthodontic treatment.

Alterations in the mucogingival complex will occur during orthodontic tooth movement, but these are independent of the apico-coronal width (height) of the gingiva. The integrity of the periodontium can be maintained during orthodontic therapy also in areas that have only a minimal zone of gingiva. In terms of changes in the position of the soft tissue margin and in gingival dimensions, the important factors to consider are the direction of the tooth movement and the bucco-lingual thickness of the gingiva. Lingual tooth movement will result in an increased bucco-lingual thickness of the tissue at the facial aspect of the tooth which results in coronal migration of the soft tissue margin (decreased clinical crown height). Facial tooth movement, on the other hand, will result in a reduced bucco-lingual tissue thickness and thereby a reduced height of the free gingival portion and an increased clinical crown height. The risk for development of recession type defects in conjunction with orthodontic tooth movement is present only if the tooth has been moved out of the alveolar bone housing, ie, when an alveolar bone dehiscence has been created.
