PENATALAKSANAAN GIANT SIALOLITH PADA KELENJAR SUBMANDIBULA (LAPORAN KASUS)

We describe a case report of giant sialolit of Wharton's duct in a 46 years old man. This is an unusual presentation of a salivary calculus and to our knowledge such a huge salivary stone. The clinical symptoms and signs were somewhat typical and included acute suppurative cellulitis in the floor. This kind of stone is very interesting because of its large size in this case, of a surgical intervention by extraoral extirpation of the presented sialolith

Polyetheretherketone (PEEK) for making bone implants in maxillofacial reconstruction surgery

Polyetheretherketone (P.EEK) has been used as a bone implant because it has the nature of a biocompatible, strong, non-corrosive, stable and not affected by high temperatures. PEEK is potential for use as an implant material. Applications in maxillofacial reconstruction surgery is very beneficial in terms of time and cost. Modelmaking mandible obtained from data on patients affected by tumor ameloblstoma. The data have been taken by a CT-scan in the form of DICOM (Digital Imaging and Communication in Medicine) is amended by Catya into STL files (stereolithography). STL file is then printed with 3D-printers and Computer Numerical Control (CNC) machines.Printouts based models have been created for the reconstruction implants in maxillofacial surgery

Morphological variability in unrepaired bilateral clefts with and without cleft palate evaluated with geometric morphometrics

In subjects with orofacial clefts, there is an unresolved controversy on the effect of congenital maxillary growth deficiency vs. the effect of surgical intervention on the outcome of treatment. Intrinsic growth impairment in subjects with orofacial clefts can be studied by comparing facial morphology of subjects with untreated cleft and unaffected individuals of the same ethnic background. Bilateral cleft lip and palate is the most severe and least prevalent form of the orofacial cleft. The aim of this study was to compare facial morphology in subjects with unrepaired complete bilateral clefts and unaffected controls using geometric morphometrics. Lateral cephalograms of 39 Indonesian subjects with unrepaired bilateral complete cleft lip and alveolus (mean age: 24 years), or unrepaired bilateral complete cleft lip, alveolus, and palate (mean age: 20.6 years) and 50 age and ethnically matched controls without a cleft (25 males, 25 females, mean age: 21.2 years) were digitized and traced and shape variability was explored using principal component analysis, while differences between groups and genders were evaluated with canonical variate analysis. Individuals with clefts had a more pronounced premaxilla than controls. Principal component analysis showed that facial variation in subjects with clefts occurred in the anteroposterior direction, whereas in controls it was mostly in the vertical direction. Regression analysis with group, sex, and age as covariates and principal components from 1 to 6 as dependent variables demonstrated a very limited effect of the covariates on the facial shape variability (only 11.6% of the variability was explained by the model). Differences between cleft and non-cleft subjects in the direction of facial variability suggest that individuals with bilateral clefts can have an intrinsic growth impairment affecting facial morphology later in life.</p

Evaluation of Heavy Metals Content, Mutagenicity, and Sterility of Indonesian Coral Goniopora sp. as Bone Graft Candidate

It has been reported that Goniopora sp. coral originating from sea water can induce osteogenesis and regeneration of bone. However, biocompatibility and safety aspects of this material have not been reported yet. We have evaluated the mutagenicity of the raw material and the sterility of processed material of Indonesian coral Goniopora sp. as a potential candidate for osteogenic bone graft. In addition, heavy metals were also identified and determined. A mutagenicity test was conducted using the Ames test, while a sterility test was carried out based on the direct inoculation method. The heavy metals tested "“ including arsenic, lead, cadmium, chrome, cobalt, silver, and mercury "“ were analyzed by neutron activation analysis or atomic absorption spectrophotometry. The results showed that the Indonesian coral did not display mutagenic properties and proved sterile after irradiation. Arsenic, lead, cadmium, mercury, chrome, cobalt, and silver were identified at a concentration level of ≤ 2.65, ≤3.60, 25.23, 1.72, 34.67, 0.51, and 44.01 ppm, respectively. Taking into account arsenic, lead, cadmium and mercury contents and their provisional tolerable daily intake (PTDI) values, the maximum daily safe exposure level of Indonesian coral Goniopora sp. was predicted to be 1 g/person. It was concluded that the coral can be developed as a potential osteogenic bone graft

Long-term follow-up of mandibular dental arch changes in patients with complete non-syndromic unilateral cleft lip, alveolus, and palate.

Background Treatment of cleft lip and palate (CLP) requires a comprehensive interdisciplinary approach and long-term follow-up. Only a few studies are available that reported on changes after treatment, which showed that in particular the transverse dimension, in patients with CLP is prone to changes after treatment. However, those studies did not pay attention to concomitant changes in the mandibular arch that occur after treatment. Objectives To evaluate mandibular transverse dental arch dimensions and interarch transverse changes in patients with complete non-syndromic unilateral cleft lip, alveolus, and palate (CUCLAP) up to five years after treatment. Material and Methods Retrospective longitudinal study in 75 consecutive patients with CUCLAP directly after comprehensive treatment (T0), two (T2), and 5 years after treatment (T5). Great Ormond Street, London and Oslo (GOSLON) scores were available for all patients. Three-dimensional scans of all dental casts were made. Inter premolar and intermolar distances between the mandibular contralateral teeth were measured. The modified Huddart Bodenham (MHB index) was applied to assess the transverse interarch relationship. Paired t-tests and ANOVA were used to analyze transverse and interarch transverse changes. Linear regression analysis was done to define contributing factors. Results Paired t-tests showed a significant decrease of the mandibular inter first and second premolar distances (p < 0.05) and an increase of the inter second molar distance, whilst the MHB Index deteriorated at all time points for all segments and for the total arch score (p < 0.05). Linear regression showed no significant contributing factors on the decrease of the transverse distances. However, inter arch transverse relationship was significantly affected by age at the end of treatment, missing maxillary lateral incisor space closure, and the GOSLON Yardstick score at the end of treatment (p < 0.05), especially during the first two years after treatment. Conclusions Changes occurred in the mandibular arch expressed as changes in the transverse dimensions and interarch relationship measured by the MHB Index. A younger age at the end of treatment, space closure for a missing maxillary lateral incisor and a higher GOSLON score at the end of treatment negatively influence the interarch transverse deterioration especially in the first two years after treatment. For the transverse dimensional changes in the mandibular arch such influencing factors could not be determined
