Abstract

Enamel demineralization that occurs adjacent to directly bonded orthodontic attachments is of great concern to orthodontists. One of the suggested procedures to overcome this problem is to use topical fluoride treatment after acid etching. The purpose of this study was to evaluate the failure rate of stainless steel bracket with metal mash base after topical application of(1.1%) neutral sodium fluoride gel after(37%) phosphoric acid etching. Twenty patients with full maxillary and mandibular "0.018" standard edgewise fixed appliances were included. Maxillary right, mandibular left sides were received the topical sodium fluoride gel application after etching with(37%) H3PO4 for(30) seconds. The gel was applied for(4) minutes after etching, then rinse with air and water stream for(5) seconds; while in the contralateral sides the bonding was done conventionally. The bonding adhesive was the No-Mix chemical cure adhesive. The follow-up period was(12-15) months. The results showed that brackets failure rate in fluoridated group did not differ significantly from the non-fluoridated one. Hence the(1.1%) neutral sodium fluoride may have a clinical application in preventing demineralization that occurred around and under orthodontic brackets without any significant increase in failure rate of stainless steel brackets

Abstract

The majority of the detected increment in dental caries is confined to pit and fissure surfaces of teeth. Application of pit and fissure sealants and topical fluorides are widely used procedures in the prevention of decay.The purpose of this study was to evaluate the effectiveness of pit and fissure sealant with and without topical fluoride application in the prevention of dental caries on the occlusal surfaces of teeth in children.93healthy cooperative children of both sexes with an average age (7-9 years) were included in this study, accordingly, 120 permanent first molars that were caries-free and fully erupted divided into two groups: sealant group (sealant applied on 60 permanent first molars) and sealant withfluoride group (sealant plus fluoride gel applied topically every three months intervals for 24 months on 60 permanent first molars). All children were recalled for assessment of fissure sealant and the presence or absent of dental caries at intervals of 6, 12, 18 and 24 months.The statistical analysis shows that there was no significant differences in the presence and absent of dental caries on the occlusal surfaces of the teeth between sealant group and sealant with fluoride group at baseline time and at 6, 12, 18 and 24 months intervals of recall assessment.There was some evidence about the superiority of pit and fissure sealant over topical fluoride application in the prevention of occlusal decay. However, it remained unclear to what extent there is differences between the effectiveness of pit and fissure sealant with and without topical fluoride application. No recommendation for the clinical practice could be given and the benefit of pit and fissure sealant with and without topical fluoride application should be considered locally and individually.

غالبية الزيادة في الكشف عن تسوس الأسنان يقتصر على ختم تجويف وشق الأسنان. وتستخدم على نطاق واسع ختم التجويف والشقوق والفلورايد الموضعي للوقاية من التسوس. كان الغرض من هذه الدراسة تقييم فعالية ختم التجويف والشقوق مع وبدون استعمال الفلورايد الموضعي في الوقاية من التسوس على سطوح الأسنان عند الأطفال.93 طفلا متعاونا وصحيا من كلا الجنسين يبلغ متوسط أعمارهم (6-9 سنوات) ادرجو في هذه الدراسة, وفقا لذلك,(120) من الأضراس الدائمة الأولى خالية من التسوس والتي بزغت بالكامل في الفم قسمت إلى مجموعتين: مجموعة الختم (60 ضرس دائمي أول) ومجموعة الختم مع الفلورايد (استعمال هلام الفلورايد موضعيا كل ثلاثة أشهر لمدة 24 شهر على 60 ضرس دائمي أول). جميع الأطفال استدعوا لتقييم ختم الشق وكذلك وجود أو غياب تسوس الأسنان على فترات 6, 12, 18 و24 شهرا.أظهر التحليل الإحصائي عدم وجود فروق ذات دلالة إحصائية في وجود وغياب التسوس على سطوح الأسنان بين المجموعتين في وقت خط الأساس وبعد 6, 12, 18 و 24 شهرا في فترات الاستدعاء للتقييم. كان هناك بعض الأدلة حول تفوق ختم التجويف و الشق على استعمال الفلورايد الموضعي في الوقاية من تسوس سطوح الأسنان. مع ذلك, فانه لا يزال غير واضح إلى أي مدى هناك اختلافات بين فعالية ختم التجويف والشق مع وبدون استعمال الفلورايد الموضعي.ا يمكن إعطاء أي توصية للممارسة السريرية وينبغي النظر في الاستفادة من ختم التجويف والشق مع وبدون استعمال الفلورايد الموضعي محليا وبشكل فردي. كلمات مفتاحية: ختم التجويف والشق, الوقاية من التسوس, الفلورايد الموضعي, تجربة سريرية.

Abstract

This study aims at investigating the scope of topical acidulated phosphate fluoride (APF) gel effect on initial carious lesions, evaluating the effect of the gel on newly erupted teeth, as well as on the low-, moderate, and high-risk School children.A sample of (340) school children [177 (52.06%) males and 163 (47.94%) females]initially in the fourth grade (aged 9-11 years) were collected from (4) Primary schools in Mosul city center, The children were allocated randomly to one experimental group (received topical APF gel) and one control group (did not receive any fluoride therapy).The dental examinations were done using DMFT index: one before fluoride application and the other after one year. It can be observed from this study that the topical APF gel is effective on initial lesions. Moreover, the efficacy of the gel on the newly erupted teeth, including chose teeth erupted during the study, is found to be greater than on the previously erupted ones. The results also reveal that the high - risk groups are the most benefitted from the fluoride treatment than the moderate- and low-risk groups. The percentages of caries reduction were (96.700%), (74.880%), and (36.071%) for the three groups, respectively.So, the use of such a fluoride therapy as a school-based programme is advised for all children with evidence of dental caries, and is recommended to be planned to match the pattern of eruption of teeth.
