One factor that make bonding agent adhere to dentine surface maximally is the humidity condition around the dentine surface. The best bond strength between bonding agent with dentine surface is depending on the moist surface. It mean that the dentine surface should neither too dry or wet. The objective of this research is to know the tensile bond strength of hydroxyethyl methacrylate (HEMA) bonding agent to bovine dentine surface at various humidity. The bovine dentine was grounded to give flat surface, which was then etched with 37% phosphoric acid for 15 seconds. Dentine was washed with 20 ml water and dried with blot dry technique. The dentine, except the control group, was placed in a desiccator for one hour at difference humidity. Dentin was removed from desiccator, then covered with bonding agent and put into tensile tool plunger. Self-cured acrylic resin was applied on this bonding agent layer, which was placed on opposite-plunger. After 24 hours, tensile bond strength was measured with Autograph instrument. Data was statistically analyzed with One-Way ANOVA at 95% confidence level, continued with LSD test. Results of this study showed that 60%–90% humidity gave produce the lower of tensile bond strength of bonding agent to dentine surface (p ≤ 0.05). In conclusion, the treatment in 60% humidity gave the greatest tensile bond strength.

Hybrid ionomer cement or resin modified glass ionomer cement is a developed form of conventional glass ionomer cement. This hybrid ionomer cement can be eroded if in direct contact with acid solution which will affect surface hardness. The aim of this study is to learn surface hardness of hybrid ionomer cement after immersion in methyl salicylate 0.06% (pH 3.6) and povidon iodine 1% (pH 2.9) solution. Sample of hybrid ionomer cement with 5 mm diameter and 3 mm thickness was immersed in sterile aquadest solution (control), methyl salicylate pH 3.6, povidon iodine pH 2.9 for 1 minute, 7 and 14 minutes. Surface hardness was measured with Micro Vickers Hardness Tester. The obtained data was analyzed statistically with ANOVA followed by LSD test. The result of hybrid ionomer cement after immersion in sterile aquadest, methyl salicylate 0.06% pH 3.6 and povidon iodine 1% pH 2.9 for one minute, showed no significant difference; while immersion for 7 and 14 minutes showed a significant difference. The conclusion states that hybrid ionomer cement after 14 minutes immersion in povidon iodine 1% pH 2.9 has the lowest surface hardness.

Sinusitis is a frequent complication of allergic rhinitis. Theoretically, sinusitis could be found in human since infancy. The prevalence of diagnosed sinusitis is 20% of ambulatory patients in daily practice. Unfortunately, a lot of sinusitis cases must be treated by surgical operation. Other cases are treated conservatively with decongestants, corticosteroids, antibiotics and diathermy. However, dental treatment approach for sinusitis management is rarely discussed. Headache, especially migraine is also a common problem in children. Sinusitis and migraine, are closely related; sinusitis sufferers often accompanied by migraine and vice versa. This phenomenon resulting in misdiagnosis of the main etiology of sinusitis and migraine; if this case happens in young children, the diagnosis should be more complicated. Dental procedures which may directly reduce the periodontal inflammation were done to children diagnosed as sinusitis by otolaryngologist and pediatrician. In a short period of time, the sinusitis and headache symptoms subsided. The objective of this case reports is to propose the possible explanation of the neurogenic switching mechanism cut off, that resulting in the instant relief of sinusitis and headache symptoms. Regarding the immediate relief of the symptoms, the role of autonomic nervous system should also be considered. Since parasympathetic innervations of nasal, sinus mucosa and maxillary periodontal tissues originated from the sphenopalatine ganglion; the conclusion is that the periodontal inflammation may sensitize the sphenopalatine ganglion which may trigger sinusitis and headache in children.

Child abuse is defined as those acts or omissions of care that deprive a child from the opportunity to fully develop his or her unique potentials as a person either physically, socially or emotionally. The overall incidence of child abuse is not really clear. Statistical data do not show the actual rate because of the unreported cases. Dentists are in a strategic position to recognize and report the children being abused because they often see the child and parents interacting during multiple visits and over a long period of time. The orofacial region is commonly traumatized during episodes of child abuse. The characteristics and diagnostic finding of child abuse, and the protocol of reporting such cases, should be familiar to the dentist so that appropriate notification, treatment and prevention of further injury can be instituted. Dentists with experience or expertise in child abuse and neglect will strengthen their ability to prevent and detect child abuse and neglect and enhance the ability to care for and protect children. This paper discusses the oral and dental aspects of child abuse and the dentist role in evaluating this situation including prevention of child abuse.

The bone defect due to tooth extraction contributes the most cases reported in the aspects of oral surgery. The defect can be preventively managed by adding powder bone matrix intended for augmentation which eventually induces the formation of new bones. This hard tissue wound healing is preceded by the presence of collagen fibers. The aim of this study was to determine the density of collagen fiber in the alveolus mandibular bone of rabbit which was augmented using powder demineralized bone matrix (DBM) post incisivus extraction. Twenty four male rabbits aged 2.5–3 months weighed 900–1,100 grams were randomly divided into two groups. The treated rabbits were augmented with DBM after the incisivus extraction on mandible. The mucosa was then sutured. On the other hand, the controlled rabbits received similar treatments with those of the treated rabbits except there was no augmentation of DBM. Decapitation of treated and controlled rabbits was made on day 5, 7, 10, and 14 days post surgery, each with three rabbits. Mandibles were cut, decalcified, and imbedded in paraffin block. The staining was done using Mallory. Significant differences in the density of collagen were noted on day 10 and 14 post surgery, indicating that powder demineralized bone matrix successfully induced the stimulation of collagen.

Globalization including General Agreement on Trade in Services (GATS) and Asia Fair Trade Agreement (AFTA) are a new free trade system. In globalization era, there will be an intense and free competition in looking for jobs throughout the world. This new system will affect the health services system in which health services tend to follow an industrial model. Meaning that dentistry or dental health services tend to be part of a business system, and this system has caused controversy among the community and the profession itself. The results of the discussion revealed that professional and business of dentistry is compatible and complementary. The tendency of increasing number of legal form of practice (group and a professional corporation) and the worldwide advertisement of these practices supported the premise that delivering dental practice tends to follow the industrial model. Dentists should not only more focus on achieving financial success in running the business of practice but profession should have the most concern for the people who seek their services. Delivering quality of dental care depends on the high skill of the dentist and on the satisfactory income for the survival of the practice in the long run, and this make the practice will be viewed by the public and profession as being appropriate and of high quality. Facing the globalization, besides possessing high clinical skill, dentists must have a firm understanding of management concepts and apply them in their practice. In conclusion: The profession and the business of dentistry are compatible and complementary. The delivery of the dental services tends to follow the industrial model, which is a current reality. Dentist should concern more on the delivering high quality of dental services, not only focus on the business of the practice, although the satisfactory income is important for the survival growth of the practice in the long run. It is suggested for dentists to follow as much business training or dental practice management training as the dentist can. It is also suggested to give the undergraduate students the basic concepts of dental practice management by putting this in the curriculum.

The high success rate of immediate implant placement both in the anterior and posterior regions were reported by many authors, therefore applying this techniques can be considered as a safe surgical procedure and minimizing the dental office visit for patient satisfaction. This paper reports the outcome of immediate placement of implants following extraction of anterior maxillary teeth. Combination technique of immediate and submerge implant placements including bone grafting procedure were used. Four implants with TiUnite surface type were placed immediately in two patients with the short-term result indicated that this technique may serve as a simple and safe procedure for immediate implant placement. It was concluded that immediate implant placement technique combined with TiUnite implant surface was successful in treating region directly after tooth extraction therefore this technique can be use as an alternative surgical method for dental implant rehabilitation.

The habit of nocturnal bottle or breast-feeding has been reported to be a potential cause for early childhood caries (ECC) in very young children. The aim of this study was to determine the prevalence of ECC in children 2-5 years of age attending out patient clinic HUSM, in relation to the nursing habits. In this cross-sectional study, 90 children were randomly selected to examine their caries status using torch and disposable mirror. Data on mothers’ educational level, nursing habits and oral hygiene practices, were gather by using structured questionnaire. It has been found that 16.7% of subjects were caries free while 83.3% of them had caries with mean dmf score 6 (SD 5.3). With regard to nursing habits, 29% of subjects had breast-feeding alone, 16% had bottle-feeding alone and 55% had both breast and bottle-feeding. Ninety-three percent of children had been nursed beyond 14 months and 47% had been fed with liquids other than breast milk, infant formula or water. Twenty-seven percent of children were allowed to sleep with nursing bottle in mouth and 52% were allowed to sleep with breast nipple in the mouth which shows significantly associated with ECC (p = 0.03). Tooth brushing habit was reported for 91% of children using toothpaste. Mean age of the children (in months) when the mothers started brushing the teeth was 19.1 (SD 10.8) and has significant association with ECC (p < 0.05). This study demonstrates that the habit of allowing infants to sleep with breast nipple in their mouth and the late start of tooth brushing are associated with prevalence of ECC. Educational programs for pregnant women and mothers of young children should be emphasized to enhance the knowledge and awareness of mothers in preventing ECC.

Oral lichen planus (OLP) is a chronic inflammatory disease of the oral mucous membrane which is characterized by unpredictable exacerbation and remission. The pathognomonic of oral features of OLP are hyperkeratotic striation surrounded white patches of mucosal erythema are called Wickham’s Striae. Chronic inflammation or epithelial damage of the mucous membrane often followed by candidosis as secondary infection. Candida species are commensal microorganism, its population in oral cavity reach 70% of the oral microorganism. It is harmless, but it could become opportunistic pathogen when the condition of oral environment support, i.e. decrease of oral immune response or the oral microorganism ecosystem change. This purpose of the paper was to report the case of a female patient (49 years old) who came to the clinic of Oral Medicine Faculty of Dentistry Airlangga University Surabaya with clinical and mycological evidence of thrush (Oral acute pseudomembrane candidosis). The patient not only suffered thrush, but also chronic cervicitis vaginalis. So the patient also consumed the antibiotic which was given by gynecologist. The used of the antibiotic for chronic servicitis vaginalis was the contrary treatment of oral thrush, after treated with nystatin oral suspention, clinical examination showed clearly hyperkeratotic lesion (Wickham’s striae), and hystopathological test result showed that it was OLP. The chronic oral inflammation and epithelial damage (OLP) or antibiotic consumption could inhibited the candidosis treatment. The case report suggested that the first treatment should be given antimicotic if the mycological test of candidosis showed positive result.
