Oral-facial-digital syndrome, Type I: a case report.

Oral-facial-digital syndrome is a group of congenital anomalies, which affects the face, oral structures and digits. There are nine subtypes. OFDS type I, is x-linked dominant trait mostly affecting females. Reports of OFDS type 1 in Asians are extremely rare. This paper shows a case of OFDS type 1, in a southern Chinese girl, who in addition to most of the classic features, had fusion of the mandibular canine and lateral incisor teeth.

Clinical evaluation of a patient with single maxillary central incisor.

Hypodontia in permanent dentition is the most common developmental anomaly and frequently found in the second premolar and maxillary lateral incisor In the primary dentition, however, hypodontia appears to be less frequent, with the exception of cases such as ectodermal dysplasia and cleft lip and palate. We report a child with one primary maxillary central incisor at midline. The presence of a single permanent maxillary central incisor was also confirmed by radiological examination. Other intraoral abnormalities were detected including absence of upper labial frenulum and abnormal palatal structure, but no other facial or brain anomalies. Although the condition is exceedingly rare, a thorough examination for more serious anomalies should be conducted since it is suggested to be the mildest feature of holoprosencephaly.

Analysis of the consistency of objective measures of sexual arousal in women.

Eight adult women volunteers viewed the same erotic film in two different sessions. Their resulting genital responses were recorded simultaneously by three different measures: vaginal pressure pulse, vaginal blood volume, and labial temperature change. During the erotic stimulation, the vaginal pressure pulse and labial responses always increased, and the vaginal blood volume response increased on all but two occasions. Although there was considerable intersubject variability in each genital measure, all three measures were found to have some intrasubject consistency over sessions with respect to either their response amplitudes or patterns, with labial temperature being the most consistent on both parameters. The relationship between the response patterns of the three measures during the film was also relatively consistent across sessions, as was the correspondence between subjective ratings of arousal and both vaginal pressure pulse and labial responses but not vaginal blood volume response. To overcome the problem of considerable intrasubject variability of response amplitudes, it was suggested that the inclusion in the data analysis of several parameters of response patterns, which were relatively stable over sessions, might facilitate the evaluation of a treatment.

A contiguous mucosal graft.

The contiguous mucosal graft is designed primarily for use in vestibular deepening but may serve as an adjunctive technique in the management of other mucogingival defects. A large amount of donor material can be obtained by this procedure which is relatively simple to perform and generally unattended by surgical complications of hermorrhage and excessive pain. Its benefits are esthetic as well as functional since the replaced tissue reproduces the original both in appearance and histological details.

Gingival recession in the lower incisor region of 15-year-old subjects.

A sample of 1,003 children, aged 15 years, were examined for prevalence of gingival recession. It was found that 17% had pseudo gingival recession and 1% had true recession. The highest degree of association with local etiological factors was that between recession and the width of keratinized gingiva; frenal pull was the second most highly associated factor followed by tooth arch relationship and the least association existed between plaque and gingival recession. There was no association between calculus and recession.

The frenectomy combined with a laterally positioned pedicle graft. Functional and esthetic considerations.

In many cases it is necessary to perform a frenectomy to prevent reopening of a midline diastema following closure by orthodontic therapy. Often the loss of the interdental papilla between the maxillary incisors during the classic frenectomy creates an unacceptable esthetic result. A surgical technique combining a frenectomy with a laterally positioned pedicle graft is presented. The interdental papilla is left surgically undisturbed if it is of physiologic size. If it is enlarged, gingivoplasty is performed to reduce it to an appropriate size. Closure across the midline by laterally positioning gingiva and healing by primary intention results in attached gingiva across the midline. This attached gingiva may have a bracing effect and thus aid in preventing orthodontic relapse (reopening of the diastema). Twenty-seven cases were treated. No relapse was found in 24 cases and in 3 cases only minimal relapse was noted (less than 1 mm). The esthetic result is superior to that obtained with the classic frenectomy technique.

A study of the association of fraenal attachment, lip coverage, and vestibular depth with plaque and gingivitis.

The effects of fraenal attachment, upper lip coverage, and mandibular vestibular depth on plaque and bleeding indices in the maxillary and mandibular anterior segments were studied in a group of 1015 school children aged 11.5 to 12.5 years. The position of the mandibular labial fraenum was relatively unimportant to plaque and mandibular gingivitis, but anterior fraenal attachment in the maxilla appeared to affect the retention of plaque and the degree of gingivitis. Maxillary and mandibular plaque and bleeding scores increased with decreasing upper lip coverage at rest. In the mandibular anterior segment, plaque and bleeding indices decreased with increasing vestibular depth. Further analysis demonstrated that fraenal attachment and vestibular depth and fraenal attachment and lip coverage were significantly associated. However, two-way analysis of variance indicated that the influence of fraenal attachment, vestibular depth, and lip coverage on plaque and gingivitis was independent. The influences of these soft tissue variables on plaque accumulation and gingivitis were of small clinical significance and not in themselves a justification for mucogingival surgery.

Angioedema as a complication in periodontal surgery: report of a case.

Angioedema is a diffuse swelling of the subcutaneous or submucosal tissues that occurs in both hereditary and non-hereditary forms. It can be a temporarily disfiguring condition, but not usually a serious one unless the airway is compromised. In the majority of cases, no underlying cause can be identified. In this report, a case of "idiopathic" angioedema that occurred while performing a periodontal surgical procedure is presented. This case is interesting because the patient was on long-term use of an angiotensin-converting enzyme [ACE] inhibitor for hypertension, and recent evidence has shown that ACE inhibitors suppress the breakdown of circulating bradykinins. With high plasma levels of bradykinins, a local anesthetic, periodontal surgical procedures, or even emotional stress may trigger an attack of angioedema. Practitioners should be aware of the pharmacologic side effects of ACE inhibitors and be prepared to handle an emergency if a patient's airway becomes compromised.

Creeping attachment associated with the connective tissue with partial-thickness double pedicle graft.

The occurrence of creeping attachment has been documented with epithelialized autogenous masticatory mucosa grafts (free gingival grafts) and suggested in other root coverage techniques. The purpose of this study was to examine whether or not creeping attachment occurred after a connective tissue with partial-thickness double pedicle graft had been performed. This study examined 22 defects, in 19 patients, treated where less than complete root coverage was obtained at 4 weeks postoperative. Creeping attachment occurred in 21 of the 22 defects (95.5%), in 18 of the 19 patients (94.7%). Complete root coverage occurred in 17 of the 22 defects (77.3%), in 15 of 19 patients (78.9%). The mean creeping attachment obtained was 0.8 mm. Additionally, it was the goal of this study to see if any factor could be associated with creeping attachment. This study did not find any factors that could be associated with the amount of creeping attachment seen. Creeping attachment seems to occur commonly, but complete root coverage is not predictable.

Neurogenic vasodilatation of canine isolated small labial arteries.

Mechanisms underlying vasodilatation to nerve stimulation by electrical pulses and nicotine were analyzed in isolated canine small labial arteries. Transmural electrical stimulation (5 and 20 Hz) produced a contraction followed by a relaxation in labial arterial strips denuded of the endothelium, partially contracted with prostaglandin F2alpha. The contraction was abolished by prazosin or combined treatment with alpha, beta-methylene ATP. In the treated strips, neurogenic relaxation was abolished by NG-nitro-L-arginine (L-NA), a nitric oxide (NO) synthase inhibitor, and restored by L-arginine. The D-enantiomers were without effect. Nicotine (10(-4) M) also relaxed the arteries, in which the contractile response was abolished by prazosin and alpha, beta-methylene ATP. The relaxant response was attenuated but not abolished by L-NA; the inhibition was reversed by L-arginine. The remaining relaxation by nicotine was abolished by calcitonin gene-related peptide (CGRP)-[8 to 37], a CGRP1 receptor antagonist. Relaxations elicited by a lower concentration of nicotine (2 x 10(-5) M) sufficient to produce similar magnitudes of response to those induced by 5-Hz electrical nerve stimulation were also inhibited partially by L-NA. Histochemical study with the NADPH-diaphorase method demonstrated positively stained nerve fibers and bundles in the arterial wall, suggesting the presence of neuronal NO synthase. It is concluded that the relaxation induced by electrical nerve stimulation of small labial arteries is mediated exclusively by NO synthesized from L-arginine in nerve terminals, whereas nicotine in the concentrations used evokes relaxations by a mediation of nerve-derived NO and also CGRP, possibly from sensory nerves. The reason why nicotine but not electrical pulses stimulates sensory nerves and elicits vasorelaxation remains unsolved.

[The choice of the sequence of operations on the periodontal tissues].

Operations on periodontal tissues and accessory operations, such as frenulo- or vestibuloplasty, have always been difficult for beginning practitioners. Analysis of 8-year practical work of a periodontologist--296 operations (57 accessory operations and 239 operations on periodontal tissues) disclosed the regularities in such interventions, related to patient's age and sex and the percent ratio of each operation, determined the rational order of operations, and demonstrated the prophylactic efficacy of accessory operations (frenuloplasty or vestibuloplasty).
