摘要:

Abstract. Traumatization of oral hard and soft tissues connected with mechanical oral hygiene procedures has been reported in the dental literature. Definitions, classifications and localization of such lesions are listed, andin vivoandin vitroexperiments within the field are reviewed. Existing literature suggests that hard tissue lesions are mainly due to abrasives in dentifrices, whereas gingival lesions may be caused by toothbrushing per se. Factual knowledge about the prevalence, severity and critical significance, as well as relevant and reliable experiments, is scarce and further research on these topics seems to be indicated.

摘要:

AbstractOne hundred infrabony pockets with one‐ and two‐wall bony defects were treated for reattachment. Mucoperiosteal flaps were raised, the tooth surfaces were scaled and planed, and the defects curetted. Flaps were sutured tightly and the sites protected with a surgical dressing. Antibiotic coverage was used in each case. Pre‐ and postoperative measurements were taken by the same clinician from the cemento‐enamel junction to the base of the pocket.In 56 defects cancellous bone from the same patient was placed in the defect, and in 44 defects the treatment consisted only of open curettage without bone grafts. The results showed a trend towards more favourable clinical results using bone grafts; especially in the two‐wall bon

摘要:

AbstractThe experiments were performed in five dogs fed a soft diet which allowed dental plaque accumulation. Experimental periodontal breakdown was introduced on Day 0. After 180 days trauma from occlusion was produced in4P and P4, i.e. the mandibular fourth premolars, in the manner described by Svanberg&Lindhe (1973). On Day 280 the periodontal pockets around4P and P4were eliminated. A notch was prepared in the root at the level of the bottom of the surgically eradicated pocket. In addition, the occlusal trauma in the4P region was deleted. From Day 280 to Day 370 the teeth of the animals were brushed twice a day. The animals were then sacrificed, radiographs of the premolar regions were taken, and tissue sections comprising3P4P1M (and P3P4M1) were produced and subjected to microscopic analysis. The results indicate that jiggling type occlusal trauma and tooth hypermobility are not factors which detrimentally affect healing following periodontal surgery.

摘要:

AbstractThe possible effects of ultrasonic scaling of all maxillary teeth for a total of 5 min on the inner ears of 20 healthy young adults, 22‐36 years of age, were investigated by means of pure tone audiometry. Audiograms were obtained just before and immediately after scaling. Temporary shifts in hearing threshold (TTS) of 10‐20 dB, mostly at 7‐8 kHz, persisting for up to 30 min, were recorded in eight of the individuals. Three patients reported high‐pitched tinnitus lasting for 20‐30 min after ultrasonic scaling. When audiograms were obtained 3‐5 weeks later in the same 20 individuals before and immediately after they had kept their mouths open for 5 min, but with no scaling performed, TTS was recorded in three of the individuals. TTS after opening only was less pronounced than TTS after ultrasonic scaling, both with regard to severity a

摘要:

AbstractThree young patients with gingival injuries that were self‐inflicted by a fingernail habit are presented. In each case the habit, which was provoked by a pre‐existing locus of irritation, was stopped as soon as the locus (or trigger) was identified and treated. A distinction is drawn between these types of cases, (gingivitis artefacta minor), and those of gingivitis artefacta major where the habit is more deeply entrenched and the implications more seri
