Interrelationship Between Orthodontics and Implantology in Anterior Aesthetic Rehabilitation: A Case Report

The rehabilitation of complex cases in the anterior region of the maxilla may require knowledge of several dental specialties. when dental involvement also causes bone and gingival involvement, management usually requires adjustment of gingival zenitis and bone graft to compensate for bone loss. Objective: to discuss a case of previous orthodontic treatment for implant-prosthetic rehabilitation in the anterior region. Case report: This case report describes a 40-year-old patient who came with the intention of extracting the tooth and installing a bridge. The implant-prosthetic treatment was performed after previous orthodontic treatment to adapt the gingiva and space. Conclusion: The interrelationship of specialists in oral rehabilitation improved the aesthetic and functional result of this complex case. Orthodontic mechanics and periodontics adapted the space and improved the periodontal condition before the implant was installed, resulting in a very satisfactory aesthetic, improving the patient’s selfesteem

10-year trend of tooth loss and associated factors in a Japanese population-based longitudinal study

ObjectivesWe examined the trend in the number of missing teeth in a Japanese community over a 10-year period and the potential associated explanatory factors.DesignProspective cohort study.SettingA population-based study conducted in 2007, 2012 and 2017 in Japan (Hisayama Study).ParticipantsResidents of a Japanese community aged 40–79 years undergoing dental examination in 2007 (n=2665), 2012 (n=2325) and 2017 (n=2285).Outcome measuresThe number of missing teeth, periodontal condition, dental caries experience, dental plaque index and oral health behaviours were evaluated each year. The longitudinal analysis of variation in these factors were assessed using mixed models.ResultsThe age-adjusted and sex-adjusted mean number of missing teeth decreased with time (6.80 in 2007, 6.01 in 2012 and 4.99 in 2017). The mean clinical attachment level (CAL), prevalence of periodontitis and dental plaque index decreased over the study period, while dental caries experience slightly increased. The level of oral health behaviour increased over time. Poisson mixed models showed that changes in mean CAL and dental caries experience were positively associated with the change in the number of missing teeth over time. Linear mixed models showed that changes in dental plaque index and no regular dental visit were positively associated with changes in mean CAL.ConclusionsThese findings suggest that a decreasing trend regarding the number of missing teeth in Japan might be associated with improvements in the periodontal condition due to changes in oral hygiene level and oral health behaviour.

Evaluation of periodontal condition in individuals with down syndrome: a case-control study

Ogival palate, macroglossia, anodontia, cleft tongue, delayed tooth eruption, low prevalence of caries and high prevalence of periodontal disease are the main oral manifestations of Down syndrome. The aim of the present observational study was to evaluate the periodontal condition in individuals with Down syndrome. The study included 30 individuals who were selected according to the age group to be studied, between 17 and 25 years old, in a local institution for the care of Down syndrome (DG) patients and 30 individuals who made up the control group and who did not have Down syndrome (CG), periodontal parameters were observed in both groups that were adjusted for habits. The results showed for the Plaque Index 41.2% of the individuals in the DS group while in the CG group in 45.5% without statistical difference. For the Gingival Index, it was observed that 39.7% in the DS group and in the CG group 44.2% without statistical difference between the groups (p <0.05). Family and institutional participation collaborates in the daily control of dental biofilm. In the present study, individuals in the DG group presented periodontal clinical parameters compatible with periodontal health and when compared to healthy individuals, they did not present clinical differences.

Dental effects of enzyme replacement therapy in case of childhood-type hypophosphatasia

Background Hypophosphatasia (HPP), a skeletal disease characterized by hypomineralization of bone and teeth, is caused by an ALPL gene mutation that leads to low activity of the tissue non-specific alkaline phosphatase enzyme. Although enzyme replacement therapy (ERT) was recently introduced for affected patients, no known studies have been reported regarding its dental effects related to permanent teeth and jaw bones. In the present study, we examined the dental effects of ERT in a case of childhood-type hypophosphatasia, including panoramic radiography findings used to estimate the dental age of permanent teeth and mandibular bone density. Furthermore, the effects of that therapy on the periodontal condition of the patient were evaluated by comparing periodontal pocket depth before and after initiation. Case presentation An 11-year-1-month-old boy was referred to our clinic for consultation regarding oral management. Two primary incisors had spontaneously exfoliated at 1 year 8 months old and he had been diagnosed with childhood-type HPP at the age of 2 years 2 months. Obvious symptoms were localized in the dental region at the time of diagnosis, though later extended to other parts of the body such as bone pain. ERT was started at 11 years 7 months of age, after which bone pain disappeared, and motor functions and activities of daily living improved. We estimated dental age based on tooth development stage. The age gap between chronological and dental ages was expanded before treatment, and then showed a constant decrease after ERT initiation and finally disappeared. The index for mandibular bone density (mandibular cortical width / length from mesial buccal cusp to apex of first molar) was increased after ERT initiation. Furthermore, the periodontal condition for all teeth except those exfoliated was stable after starting therapy. Conclusions ERT resulted in improved tooth and mandibular bone mineralization, with notably good effects on teeth under formation. Acceleration of mineralization of roots associated with erupting teeth leads to stabilization of the periodontal condition. We concluded that ERT contributed to the improved dental condition seen in this patient.

The Impact of Obesity on Periodontal Health Status in Adolescent Iraqi Students

Objetive: The aim of this study was to estimate the effect and association of obesity on the periodontal health status of middle school students. Materials and Methods: This study included 180 secondary school students aged 12- 15 years from Baghdad City in the survey. BMIfor-age (body mass index for age) was utilized to detect overweight and obesity. Furthermore, periodontal screening records (PSR) index was performed to evaluate the oral hygiene and periodontal condition of the subjects. Chisquare tests and two-way ANOVA were used for statistical analyses. Results: A highly significant association of BMI-for-age with periodontal health (codes 0, 1, 2, and 3) was observed. The association of gender and periodontal health was highly significant in code 3, significant in codes 0 and 1, and it was not significant in code 2. Additionally, the ANOVA test revealed that the effects of gender and BMI-for-age on periodontal health were significant. In contrast, the effect of the interaction between gender and BMI-for-age on periodontal health was not it was not significant. Conclusions: In adolescents, bad oral hygiene was correlated with extra body fat indicators. Therefore, oral health preventive schedules should take into consideration the relationship between periodontal condition and overweight/obesity in teenagers.
