Visible Light Cure (VLC) is a blue light used in dentistry as an activator for restorative material and fixed orthodontic bonding. The wavelength of VLC is between 400-500 nm and considered non-ionizing radiation that can produce free radicals. According to previous research, the light at wavelength < 500 nm could inhibit cells mitosis, cause cells damage, and reduce cells growth and inflammation. The purpose of this study was to investigate the effect of VLC exposure on gingival epithelial thickness, total neutrophil and macrophage count of gingival connective tissue of Sprague dawley rats. The subjects of this study consisted of 20 Sprague dawley rats, in 2-3 months of age and divided into 4 groups. Each group was 5 rats. The rats in each group were sacrificed before (0 day, as group A) and after 1st (group B), 3rd (group C), 5th (group D) day of VLC exposure, respectively. The exposure of VLC was done in labial aspect of cervical anterior teeth of mandible. The distance of exposure was as thick as 2 layers of celluloid strip and the histological specimens were stained by Hematoxylin Eosin. Each specimen was measured for its gingival epithelial thickness by using a micrometer and the number of neutrophil and macrophage were counted. The data of gingival epithelial thickness from 4 groups were analyzed by Kruskal Wallis. The number of neutrophil and macrophage were analyzed by u sing one way ANOVA. The results of this study showed that there were significant differences among groups on the thickness of gingival epithelial, the number of neutrophil and macrophage in the gingival connective tissue of Sprague dawley rats. The result of this study indicated that VLC exposure might decrease the thickness of gingival epithelial but increase the number of neutrophil and macrophage of gingival connective tissue of Sprague dawley rats.

The aim of orthodontic treatment is to obtain healthy, stable, and aesthetically sufficient occlusion. To achieve these objectives, malposititon teeth should be moved mesio-distally, labio-lingually, or proposed retroclination-proclination to an ideal position. Lower Incisor proclination is labially teeth movement to obtain normally dental arch, good of relation with upper teeth, and aesthetic. Orthodontic treatment effect of lower incisors proclination on gingival recession is still controversial. This paper is aimed to discuss the effects of lower incisors proclination on gingival recession. Condition of periodontal tissues is influenced by number of factors, namely individual variations in tissue morphology and their responses, applied pressure type, poor oral hygiene, age, minimal attached gingival, tooth malposition, fenestration, poor oral hygiene, alveolar bone defects, as well as mechanical trauma such as orthodontic treatment. Gingival recession has close relationship with anatomy structure, such alveolar bone thickness and height, gingival thickness and texture, as well as tooth position. Study on 11-15 years old subjects, grouped into 3, and treated with fixed appliance, removable appliance, and activator showed different depth increases in gingival sulcus during the treatment. The worst inflammation symptoms occurred in patients treated with fixed appliances. Boyd studies on periodontal status of adults, youths, and juveniles using fixed appliance showed no significant gingival recession. Condition of thin and delicate texture gingival as well as thin alveolar plate bone support is more sensitive to gingival recession than thick and fibrous gingival, supported by thick alveolar bone. When teeth which supported by very thin alveolar plate is moved labially (proclined) from jaw, gingival recession would occur. Thin supporting bone can cause release of attached gingival, resulting in recession. Tooth with adequate/normal attached gingival can undergo local recession during orthodontic treatment. It relates with excessive orthodontic force application, which impedes recovery or remodel of the alveolar bone. Based on reported results by various authors, it can be concluded that lower incisors proclination does not always cause gingival recession. It depends on several predisposition factors, including anatomy of very thin cortical alveolar bone plate, narrow attached gingival/keratin, inadequate/thin gingival structure, labially positioned lower Incisors, excessive orthodontic forces for proclination movement, far distance of proclination movement, poor oral hygiene, and age. These factors must be considered in developing treatment planning in order to avoid unnecessary risks and achieve optimal and satisfying treatment objectives.

We agree that all faculty of dentistry in Indonesia needs to contribute to dental health development. By this, hopefully we can contribute to promote oral health, prolong tooth life, and improve quality of life in our country as well as in our Asia region. To reach this goal faster, we need to exchange information and enhance scientific collaboration. The Indonesian Journal of Dental Research (The Indonesian J Dent Res) will be an effective form of communication among dentists and researchers and also a very considerable part in scientific and technological development towards the goal.Meanwhile, Indonesia is a very unique country. Although the prevalence of oral and dental diseases is considered high, but Indonesia is rich with culture, natural resources, and local or indigenous perspective which can be an advantage in term of technological perspective in dentistry. The richness of the country is needed to be investigated and explored in order to improve oral and dental health. The communication and collaboration among dentists and researchers are needed to accelerate the process towards the improvement of oral and dental health.I do hope that this journal will be an effective communication channel for better oral and dental health in Indonesia. Congratulation for the publication of the first issue of the journal. We hope to learn more from the continuous scientific communication through The Indonesian Journal of Dental Research.M.

Reconstruction of large bone defects caused by trauma, excision of tumors, and congenital malformations can be very difficult to perform. Bone engineering offers an option to improve bone reconstruction procedures. This interdisciplinary field applies the principles of biology and engineering to the development of functional substitutes for damaged bone. Our research aimed to find the ideal scaffold for bone regeneration, focusing on Calcium and Phosphate combination. In this study, Plaster of Paris (POP) was combined with CHA and implanted in femoral condyles of rats. According to the experimental result, it can be concluded that there was no significant difference in response to the implantation of POP and POP-CHA in Sprague Dawley rat femur condyle (p<0.05). It can be stated that both POP-CHA and POP shows similar trait in bone healing.

A clinical trial was carried out to investigate the effect of Anchovy of Stolephorus baganensis on mutans streptococci inhibiting the growth of the salivary mutans streptococci for a period of one week consumption.Before enrolled in the study, respondents filled out and signed the informed consent. Twenty respondents participated as the subjects on the clinical trial, conducting two times of treatment as follows: twenty astreatment groups before and after consuming anchovy of Stolephorus baganensis and the twenty subjects as control groups before and after consuming non-anchovy of Stolephorus baganensis. Saliva samples werecollected before and after consuming anchovy of Stolephorus baganensis and with a non-anchovy of Stolephorus baganensis. A serial dilution was made, followed by inoculating on TYS20B medium). Data which were obtained from colony forming units of salivary mutans streptococci grew on the TYS20B medium before and after consuming anchovy of Stolephorus baganensis were analyzed in a descriptive and “t” test.Results showed that there was no significance in the average amount of Streptococcus mutans colonies between before and after consuming non-anchovy of Stolephorus baganensis. However, a significant difference wasfound respectively as results before and after consuming anchovy of Stolephorus baganensis. We concluded that Anchovy of Stolephorus baganensis has antimicrobial activity against local strains of Streptococcus mutans isolated from human harboring species. Therefore in a long term of consuming Anchovy fish of Stolephorus baganensis, caries can be prevented.

Copper-containing zeolite has been developed as an antibacterial material. It is obtained by reacting zeolite and salt solution with varied concentration of copper. Natural zeolite is abundant in Wonosari, Yogyakarta. The aim of this research was to investigate the concentration effect of copper (II) chloride solutions towards copper ions sorption on natural zeolite from Wonosari. Copper (II) chloride dihydrate powders, CuCl2. 2H2O, (Merck, Germany) and natural zeolite (Wonosari, Indonesia) were used. Zeolite powder (100 mesh) was washed and dried (200oC/2 hours). Copper (II) chloride solution with different concentrations (0.05 M, 0.10 M, 0.15 M, 0.20 M, and 0.25 M) were prepared. Zeolite and CuCl2 solutions (50 g/250 ml) were reacted at 60oC for 1 hour (n=5). The solutions were filtered, washed, and dried (100oC/24 hours). Copper ions amount were measured by XRF (Canberra Inc., USA). The data were analyzed by one way Anova. Mean values (% weight) of copper ions amount were 0.441 Â± 0.029 % (0.05 M group), 0.588 Â± 0.027 % (0.10 M group), 0.657 Â± 0.014 % (0.15 M group), 0.676 Â± 0.037 % (0.20 M group), and 0.737 Â± 0.039 % (0.25 M group). The Anova showed that CuCl2 concentration influenced copper ions amount significantly (p<0.01). The differences among the groups were significant, except between 0.15 M and 0.20 M groups (p>0.05). Copper (II) chloride concentration influenced the copper ions sorption on natural zeolite from Wonosari. The 0.25M CuCl2 solution gave the highest copper ions amount.

Most cases report that the abnormality of bone defect is engendered by tooth extraction. The powder of demineralized bone matrix (DBM) is required to fill alveolus bone for reconstructing material or preventingtissues defect after tooth extraction. The aim of this study was to determine the density of gingival collagen fiber on wound healing after the augmentation of DBM following the extraction of incisivus tooth. In this study, 36 male rabbits aged 2.5-3 months weighing 900-1,100 grams were randomly divided into two groups: control and treated rabbits. The incisivus teeth of mandibles of treated rabbits were extracted and augmented with the allograft DBM powder. The gingival was sutured with non-absorbable sutures. The same procedures were employed to the control group, except that these rabbits were augmented with DBM powder. Subsequently, the rabbits were sacrificed on days 1, 3, 5, 7, 10, and 14 after surgery, and each observation was represented by three rabbits in the sample. The gingival (ca. 0.5-1cm) was cut and fixed immediately in 10% paraformaldehide. The staining was done using van Geison. In the treated rabbits, the density of gingival collagen fiber significantly increases in all observation days except on first day, indicating that the allograft powder of DBM successfully accelerates the wound healing process.

The purpose of this study was to evaluate whether the partnership between 26 primary schools with the Faculty of Dentistry, Universitas Gadjah Mada, during the past 12 years improved oral health status of the schoolchildren. A sample survey was carried out, involving 106 fifth and sixth graders from 9 schools which have been participating in the partnership and 90 schoolchildren from non-participating schools. They were examined by trained dental students. Oral health status was represented by OHI-S and DMF-t measurement. Knowledge and attitude of oral health were measured using structured questionnaires. The study indicated that the means of OHI-S and DMF-t among schoolchildren participating in the partnership were 0.11 and 0.01 lower respectively compared to those of their counterparts, although the differences were not significant statistically. The knowledge and attitude among schoolchildren in the partnership were 2.49, 4.18, and 3.86 higher, all were highly significant (p < 0.001). Path analyses showed that the partnership reduced OHI-S and DMF-t with an overall path coefficients – 0.086 and -0.076 respectively. Although knowledge was associated with DMF-t and attitude with OHI-S, there were other unmeasured variables which were more strongly associated with oral health status of the schoolchildren.

While measurement of mouth opening is an important clinica examination in diagnosis and management of oral disease, data on non-Western populations are limited. This study was therefore conducted to determine the range of mouth opening in normal Malaysian male and female adults. A total of 34 dental students of Universiti Sains Malaysia (USM) were chosen randomly and their maximum mouth opening was measured after being asked to open their mouth sufficiently to accommodate three fingers. Measurement was performed from the edge of the upper incisor to the lower incisor using a caliper divider. The difference of median values between male (47.6 mm) and female (40.8 mm) were significant respectively (p<0.05). Thus the width of mouth opening in Malaysian student population is gender dependent although further study with a larger sample size and with other ethnic groups should be carried out, focusing on age.

Introduction: Vertical facial morphology characterized by steepness on mandibular plane (MP-SN) is an important variable in determining orthodontic diagnosis and treatment plan. Subjects with steepest mandibular plane angle tend to have larger teeth and narrower dental arch. The purpose of this study was to determine the relationship between dental arch and vertical facial morphology on Deutero-Malays population. Materials and Methods: Lateral cephalograms were obtained from 50 subjects. Inclusion criteria of subjects were including: 1) at least two original generation of Deutero-Malays; 2) never or not under orthodontic and orthognathic treatment; 3) having Class I Angle first molar relationship; 4) having full dentition except third molars; 5) showing regular or mild degree of irregularity according to Mal-alignment Index (Mal I); 6) no cups or interproximal caries; 7) overjet 2-4 mm; and 8) overbite 1/3 incisally lower incisor teeth. Vertical facial morphology was measured by determining steepness of mandibular plane (MP-SN) on lateral cephalogram using DBSWIN program. The measurement of dental arch perimeter length and width was conducted. Collected data was tabulated and analysed using correlation test. Result: The results of this study showed no significant correlation between steepness of mandibular plane and dental arch perimeter length and width on upper and lower arch. Conclusion: In conclusion, there was no relationship between vertical facial morphology and dental arch perimeter length as well as dental arch width on upper and lower arch.
