Background: The prevalence of malocclusion in Indonesia is about 80% of the population and is a fairly common dental and oral health problem so that treatment of malocclusion from an early age is very important and needed. One of malocclusion treatment for preventing malocclusion is the use of removable orthodontic devices in the form of inclined bite plane. Con-clusion: Inclined bite plane can be made on the orthodontic plate of maxilla and mandible. In the maxilla inclined bite plane can function as a functional appliance in treatment of Class II malocclusion division 1, as a retention device after treatment using twin blocks and in the mandible serves to correct anterior crossbite.

The aim of this study was to know issue of the relationship between mandibular asymmetry and body posture. The literatures of mandibular asymmetry and body posture published in the last 10 years (2012-2022) which were collected from the electronic databases PubMed and Google Scholar. The data obtained was anaylized using observational, prospective, retrospective, case reports, systematic reviews and meta-analyses, showed that there is a relationship between themandibular and C2-3 with the rela-tion of the suprahyoid, hyoid bone, infrahyoid and sternocleidomastoid muscles connecting to spine. So, the changes in mandi-bular position will also change the body posture, and body posture will also affect the position of the mandibular with spinal de-formities which results in distortion of the vertebral column and asymmetrical face, shoulders, and waist. It was concluded that all studies cited in this literature review reported thatmandibular asymmetry and body posture have a reciprocal relationship.

This study aimed to assess the association of salivary pH, dental caries, and body mass index (BMI) in middle school students in Eastern Makassar. Material and Methods: This study included 60 middle school students from two schools in eastern Makassar. Data were collected by filling out a questionnaire, weight and height measurement, dental examination and saliva collection. Body mass index was calculated by dividing weight and height in kg/m 2 , saliva was collected by draining method, and salivary pH was measured with Saliva-Check Buffer (GC Japan). Decay Missing Filled-Teeth (DMF-T) indexes are used to assess dental caries. Statistical analysis was performed by chi-square and ANOVA with a significance of 0.05.Filled-Teeth (DMF-T) indexes are used to assess dental caries. Results: This study showed that overweight and obesity are more prevalent in female students than male students. Salivary pH in underweight students and overweight and obese students were lower compared to normal BMI students, while DMFT score in underweight, overweight and obese students was higher than the normal BMI students. Conclusion: It can be concluded that body mass index (BMI) have a significant association with salivary pH and DMFT score.

Background: Malocclusion describes anomaly conditions in orthodontics, namely occlusion abnormal conditions. The preva-lence of malocclusion in Indonesia is still high around 80%. The management of malocclusion cases needs to pay attention ear-lier compared to being alert in adulthood. The treatment that can be performed is to use an activator functional appliance to pre-vent class II malocclusion. Objective: To review how the activator functional appliance was used in the treatment of Class II malocclusion. Methods: Scientific evidence is drawn from various literature to support this paper. Conclusion: Skeletal and dental changes can be achieved with the treatment of functional devices, activators. Activators can influence mandibular growth by increasing the rate of endochondral ossification in the condyles resulting in increased mandibular length in the treatment of Class II malocclusion. The success of the functional plane depends on the patient's developmental period, skeletal disorders, and patient cooperation.
