The use of lip bumper to overcome lower lip sucking habit Marcella Budhiawan; K. Krisnawati
Padjadjaran Journal of Dentistry Vol 22, No 1 (2010): March 2010
Publisher : Faculty of Dentistry Universitas Padjadjaran

The patient was a 16-year-old girl with a lower lip sucking habit with increased overjet, maxillary and mandibular generalized spacing. Hyperactivity of the mentalis muscle and deepening of the labiomental sulcus because of the abnormal sucking habit was observed. Orthodontic treatment was started with a lip bumper appliance to break the lower sucking habit and continued with fixed orthodontic mechanotherapy. The lip bumper appliance therapy resulted in the elimination of the lower lip sucking habit, musculus mentalis hyperactivity, and labiomental strain, and also an overjet reduction. The use functional appliance in the treatment of malocclusions must be carefully selected according to the requirement of the case. It must be understood that the action of the mentalis muscle was the primary activator of the bumper.

Introduction: Tooth eruption is influenced by various factors, one of them is nutritional factors. This study was aimed to obtain information regarding the relationship between the number of permanent teeth erupted with nutritional status in 6-7-years-old children. Methods: This research was cross-sectional and correlational data analysis. The study was conducted towards as much as 57 children aged 6-7 years old. The sampling method was the purposive sampling technique conducted in Tanjungsari 2 State Elementary School, Sumedang Regency. The nutritional status was calculated based on the Body Mass Index (BMI) according to age from the anthropometric measurements of body weight and height. Assessment of nutritional status was performed using the WHO Anthroplus® v1.0.4 application. Statistical analysis was performed using the Spearman correlation test and Mann-Whitney difference test. Results: The correlation test has obtained the value of ρ = 0.037, which showed a significant relationship between the number of permanent teeth erupted with nutritional status of 6-7-years-old children. The Spearman correlation coefficient has obtained the value of r = 0.277, thus showed the weak strength and positive direction of the correlation. Conclusion: There is a relationship between the nutritional status and the number of permanent teeth erupted in children aged 6-7 years old in the Tanjungsari Sub-district of Sumedang Regency. The higher the nutritional status of a child, the more number of permanent teeth erupted.

This research aimed to identify the effect of inhaling mercury on the hepar cells of white mice and the role of green tea extract as an antioxidant on such hepar cells having exposed to mercury histopathologically. It was an experimental research by using 48 male white mice (Mus musculus) as the sample. The sample was divided into 8 groups i.e.: A, B, C, and D, which were given treatment for 3 and 6 weeks. Each group consisted of 6 mice. A group was a negative control which did not get any treatment. Group B as a positive control group was exposed to mercury. Group C was exposed to mercury and was given green tea extract at dosage 0.52 mg/20 gr of body weight. Group D was exposed by mercury and was given green tea extract at dosage 1.04 mg/ 20 gr of body weight. All white mice in the group B, C, and D were exposed to mercury through inhalation for 4 hours daily. To identified the effect of mercury, the hepar cells in all 4 groups were examined at the 3rd and 6th week by making histopathologic preparation in the Histopathology Laboratory Faculty of Medicine Universitas Andalas. Then, the preparation was examined through Binocular Light Microscope in ordered to see the deficient occurred. The data obtained were analyzed by ANOVA method and independent T-test with confidence level = 95%. It was revealed that the hepar cells that were being exposed to mercury regularly were being degenerates. Then, the amount of green tea extract given reduces the degeneration occurred.

The effect of oral habits in the oral cavity of children and its treatment Meirina Gartika
Padjadjaran Journal of Dentistry Vol 20, No 2 (2008): July 2008
Publisher : Faculty of Dentistry Universitas Padjadjaran

Oral habits include habit which is continuously done and has the potential to cause defects in teeth and perioral tissues. Some of the oral habits are finger/thumb sucking, lip sucking/biting, nail biting, bruxism, abnormal swallowing and mouth breathing. The etiology of oral habits includes the disharmonious relationship between parents and children, dissatisfaction in oral phase, premature weaning, emotional disturbance, anomaly, and diseases. Oral habits will influence the development of occlusion and perioral structures in children in the growing and development process. The treatment of oral habits can be done with or without appliances. The non-appliance treatment consists of psychological approach, medical approach and myofunctional therapy while the appliance treatment will include the use of orthodontic appliances.

Hard tissue augmentation for alveolar defects before implant placement Rochmawati, Mutia; Komara, Ira
Padjadjaran Journal of Dentistry Vol 28, No 1 (2016): March 2016
Publisher : Faculty of Dentistry Universitas Padjadjaran

Background. Often when planning implant therapy, there is a need to augment or replace bone that has been lost. The alveolar defects may occur as a result of tooth loss due to extraction, advanced periodontal diseases or trauma, long term use of removable appliances, dehiscence and fenestration defects, developmental defects/clefts, congenitally missing teeth and odontogenic cysts and tumors. Insufficient bone volume can be brought about by hard tissue augmentation. This techniques have led to increased predictability in reconstruction of alveolar ridge defects and functional implant placement. Purpose. To describe the methods of hard tissue augmentation which can be done with block grafts (autografts and allografts), particulate grafts (cortical and cancellous), xenografts, or synthetic materials. Review. The reconstruction of a normal alveolar housing, in height and width, is imperative to achieve a harmonious balance between biology, function, and aesthetics. Depending on the size and morphology of the defect, horizontal or vertical, various augmentation procedures can be used. Soft tissue management is a critical aspect of hard tissue augmentation procedures. Incisions, reflection, and manipulation should be designed to optimize blood supply and wound closure. The design and management of mucoperiosteal flaps must consider the increased dimensions of the ridge after augmentation as well as esthetics and approximation of the wound margins. The surgical procedure needs to be executed with utmost care to preserve the maximum vascularity to the flap and minimize tissue injury. Conclusion. Alveolar ridge defects can be classified by using Seibert’s classification or HVC System. The treatment of alveolar ridge defect before implant placement can be done with hard tissue augmentation.

Human tongue base cancers are characterized by a high degree of local invasion and metastasis to the regional lymph nodes and included a disease with difficult treatment. A novel method for high-efficiency and region-controlled in vivo gene transfer was developed by combining electro-gene therapy and plasmid (pcDNA). The aims of the study were to examine the efficiency of transfection of p27Kip1 gene by electro-gene therapy and to evaluate p27Kip1 gene therapy in Supri’s clone-3 (SP-C3) xenografts using pcDNA3.1-p27Kip1 wild-type (wt) and pcDNA3.1 empty vector (neo) with electro-gene therapy. To investigate gene transfer method, the enhanced green fluorescence protein (EGFP) gene was transfected into xenografts by electro-gene therapy. The efficiency of p27Kip1 gene transfection at protein level was confirmed by Western blotting. To estimate the reduction in tumour size in Wistar Balb/c mice after electro-gene therapy with p27Kip1 wt gene was examined by tumorigenesis assay. To evaluate the induction of apoptosis was carried out by colourimetric assay. The result, the growth of tumours was markedly suppressed by p27Kip1 wt gene transfection. Up-regulation of p27Kip1 protein was detected in pcDNA3.1-p27Kip1 wt. Apoptosis induction through the activity of caspase -3 and -9 was significantly increased in p27Kip1 wt-transfected tumours. These results suggest that it is possible to transfer p27Kip1 wt into tongue base cancer cell xenografts using electro-gene therapy. p27Kip1 wt had a high-potential to suppress the growth of tumours. Conclusion, electro-gene therapy followed by intratumoral injection of pcDNA3.1-p27Kip1 wt had a high-potential to suppress the growth of a human tongue base cancer cell xenograft.
