This case report compared the effectiveness of resin infiltration technique (Icon, DMG) with microabrasion (Opalustre, Ultradent Products, Inc.) in management of white spot lesions. It demonstrates that although neither microabrasion nor resin infiltration technique can remove white spot lesions completely, resin infiltration technique seems to be more effective than microabrasion. Therefore resin infiltration technique can be chosen preferentially for management of white spot lesions and caution should be taken for case selection.

This study is about the treatment effect of fluoride varnish on white lesion. The changes in microhardness values and lesion sizes were compared and analyzed in relation to application interval, frequency, etc. Resin blocks were fabricated with the crown portion of permanent molars. Samples were classified into group I(1 week), group II(2 weeks) and group III(3 weeks) based on fluoride application intervals, each with 15 samples. Samples were soaked into a decalcifying solution for 15 days, and stored in artificial saliva at $37^{\circ}C$ thermostat. The changes in microhardness values and lesion sizes, before/after decalcification and after fluoride application, were evaluated. The following results were obtained. 1. Microhardness values in group II and III exhibited almost twice the increasing rate than group I. There were significant differences between group I and II, and group I and III (p<0.05), but none between group II and III (p>0.05). 2. Change in lesion sizes showed no significant differences between group I and II, III (p>0.05). In conclusion, fluoride varnish application results in both qualitative and quantitative improvements in white lesions. The satisfactory results can be obtained when varnish is applied at more than 2 weeks interval.

Pachyonychia congenita is a very rare group of an autosomal dominant genodermatosis caused by heterozygous mutations in the keratin genes. The clinical findings affect nail and toenails, soles, and oral mucosa, etc. The main symptoms include nail and toenail dystrophy, hyperkeratosis of hands and feet, follicular hyperkeratosis, oral leukokeratosis. Many therapeutic modalities have been used to treat skin lesion, including surgical and mechanical procedures, chemical agents, medications. Oral lesions but not usually require treatment, if the patient's discomfort occurs, symptomatic therapy is performed. In the patients accompanied by oral and skin lesions, clinician have to observe specific manifestations with dystrophy of the fingernails and toenails, plantar hyperkeratosis, oral leukokeratosis and tissue biopsy is required for diagnosis confirmed.

에이즈 환자에게서 흔히 나타나는 구강 내 병변은 충치, 구강칸디다증, 구강 모상 백반증(oral hairy leukoplakia),재발성 아프타성 구내염(recurrent aphthous stomatitis),재발성 포진성 구내염(recurrent herpetic stomatitis),치주염, 카포시 육종, 비호치킨성 림프종 등이다. 이 중 에이즈 환자에게 비교적 특징적인 병변은 구강 칸디다증, 입안털백색판증, 카포시 육종 등이지만 일반인들에서 흔히 관찰되는 충치라고 하더라도 치주염이나 농양으로 빠르게 진행한다면 에이즈를 의심해 보아야 하며, 반복적인 아프타성 궤양이나 포진성 궤양이 유달리 크고 오래 지속된다면 역시 에이즈의 가능성을 생각해 봐야 한다. 구강 병소는 에이즈 환자에게서 흔히 발견되며 이 질환의 초기 상태를 제시할 수 있다는데 의의가 있다.

동물원에서 사육중인 검독수리(Aquila chrysaetos)가 구토중세를 보이다 약 111여 일간물과 사료를 절폐하였고 전신적 삭쇄, 안구에는 염증성 삼출물로 덮여 실명, 한쪽날개가 처지며 호흡곤란으로 폐사하여 부검의뢰 되었다. 부검 소견상 폐와 기낭에 회백색의 육아종 성 결절이 다수 존재하였다. 기낭은 비후되어 있었고 일부는 균사가 자라 청색을 띄는 병변도 관찰되었다. 병리조직학적으로 병변은 육아종성 괴사였으며, 병소에는 곰팡이의 균사와 소포 가 관찰되여 곰팡이성 폐렴과 기낭염이였다. 병면의 배양 결과 Aspergillus Fumigatus로 동정 되었다. 본 예는 맹금류인 검독수리에서의 Aspergillus감염 중계이다.

White lesions of the oral mucosa are a common clinical finding that often present first to general dentist. Some white lesion may have possibility of malignancy. Leukoplakia is the most common "potentially malignant disorder" of the oral mucosa. Leukoplakia is at present defined as "A white plaque of questionable risk having excluded (other) known disease or disorders that carry no increased risk for cancer.". Therefore, it is important for general dentist to be familiar to clinical differential diagnosis of leukoplakia from the known white lesions such as candidiasis, lichen planus, leukoedema, frictional keratosis, and so on. It is also important to decide whether such lesions require further investigation through the biopsy. As a result of biopsy, the presence of epithelial dysplasia in the leukoplakia is still the strongest predictor of future malignant transformation. In this article, oral white lesions that must be differentiated from potentially malignant disorders or early invasive squamous cell carcinoma will be reviewed together with presenting clinical cases.

The objective of this in vitro study was to monitor the amount of remineralization of decalcified enamel according to the number of fluoride varnish application using quantitative light-induced fluorescence-D and polarizing microscope. Artificial white lesion induced on the sound 72 teeth, $CavityShield^{TM}$ (Group I), $FluroDose^{TM}$ (Group II) and $Flor-Opal^{(R)}$ Varnish (Group III) were applied 1, 2 or 3 times every two weeks. The following results was obtained: 1. In group I, II and III, ${\Delta}L$ were increased. From regression analysis of ${\Delta}L$ by the number of application, the equation was y = 3.878x + 90.612 in group I, y = 3.133x + 37.168 in group II, and y = 3.509x + 82.322 in group III(p < 0.05). 2. In group I, II and III, ${\Delta}D$ were decreased. From regression analysis of ${\Delta}D$ by the number of application, the equation was y = -2.336x + 107.235 in group I, y = -2.158x + 101.620 in group II, and y = -1.940x + 94.806 in group III(p < 0.05). 3. The Pearson correlation value between the ${\Delta}L$ and ${\Delta}D$ was -0.673 in group I, -0.574 in group II, and -0.431 in group III(p < 0.05).

Resin infiltration has been used as a treatment option for the management of early caries lesions recently. However, the etching procedure with hydrochloric acid might be somewhat stressful for the clinicians due to safety problem especially for young children, leading to less utility. This study aims at searching for some alternative surface pretreatment methods of resin infiltration for the early caries lesions in primary anterior teeth by comparing penetration depth of various methods. No significant difference was found in penetration ratio between etched surface with 15% hydrochloric acid and 35% phosphoric acid. However, the penetration ratio was significantly higher in groups pretreated either with dental pumice or abrasive metal strip (p < .05). By the result of this study, etching with phosphoric acid as an alternative of hydrochloric acid was thought clinically acceptable as a pretreatment method for resin infiltration in early caries lesions for primary anterior teeth. It was notable that surface conditioning with dental pumice or metal strip before etching was effective in increasing the penetration. This procedural modification might be much more correspondent with minimally invasive concept and hopefully contribute to increased safety and utility in pediatric dentistry.
